Car Safety Features Essay

As cars and other motor vehicles get faster, they become more and more dangerous to use. While this is the case, there are many different methods that manufacturers have used to help prevent harm to their consumers. These methods include: air bags, seatbelts, antilock breaking systems and many more. These three features are by far the most commonly known safety features for cars, and pretty much any new car that is manufactured will have all three of these safety features, not only because of the interest in keeping drivers safe but also the recently huge appeal to safety features and ratings for cars. Seat Belts Seat belts are by far the most common safety feature among cars. Everyone knows what they are, been taught to always buckle up, they reduce the risk of death by around 50%, and is illegal to not be wearing one while travelling in a car. But exactly do seatbelts do? Seat belts protect drivers and passengers by strapping them into their seat. This prevents violent jerks caused by either collisions or sudden stops. The basic idea of seatbelts is that they stop you from flying out of the windshield of your car. Why would this happen? It happens because of something called inertia. Inertia matter’s tendency to keep moving if it’s moving or keep staying still if it’s staying still, until it becomes under the influence of a force. Kind of like if you wake up in the morning felling tired, you want to go back to sleep until you force yourself to wake up. This is how inertia works. If you were traveling in a car at 60 kilometres per hour, inertia would mean that the car, and everything inside it, would want to keep moving at 60 kilometres per hour. If the car decelerates very quickly, perhaps due to a crash, everything inside the car will still be moving at 60 kilometres per hour, but the car will be slowing down very quickly. If you were not wearing a seatbelt, you would travel forwards at 60 kilometres per hour and crash through your windshield. Since windshields are made of thick glass, crashing into it would very easily kill you at a speed like this. If you were wearing a seatbelt in a situation like this, the seatbelt acts as a force to stop you from moving forwards, greatly reducing the impact of the inertia. The most commonly known kind of seatbelt is known as the three-point seatbelt, which can be seen on the right. The three-point seatbelt is almost always used in cars and buses. The three-point seatbelt works by having a strip of fabric not only across your hip, but also across your whole torso. The seatbelt has three points, two of them being built into the car, and the third point being where the seatbelt locks in, hence the name three-point seatbelt. Air Bags Another very common form of passenger protection is the air bag. Air bags are basically just what they’re called. They are bags and get filled with air during a crash, preventing the driver/passenger from hitting their head onto the dashboard. Much like seat belts, they strive to decrease the impact of inertia to prevent injury, by stopping the passenger’s head from moving forward. Air bags have three components that work in unison to function correctly: the crash sensor, the inflator, and the air bag itself. The crash sensor is a device that detects the force that is equal to or greater than driving into a brick wall at 16 to 24 kilometres per hour. If this force is met, the crash sensor sends a command to the inflator. The inflator then creates a reaction between sodium azide (NaN3) and potassium nitrate (KNO3) to create nitrogen gas (NO3). The inflator forces this gas into the airbag, cause the bag to inflate. The bag is made of a thin nylon fabric, which is folded into a compartment in both the steering wheel and the the dashboard, and most of the time the seat or door. Anti-lock Braking System (ABS) Many accidents are cause by brakes being applies too much, locking up the wheels and cause the car to skid. ABS tries to prevent the wheel from locking up and making the car lose control. There are 4 components to ABS systems: speed sensors, the pump, valves and the controller. The speed sensors provide information to the controller of what speed the car is travelling at, they are usually located at the wheels. There is a valve in each of the brakes controlled by the ABS. There are three different positions that the valves can be in: the valve being open, blocking the break line and releasing pressure form the brakes. Since valves release the pressure from the brakes, there needs to be something that puts the pressure back in. That’s there the pump come in. When a valve reduces the pressure in the brakes, the pumps are there to put the pressure back in the brake system. And finally, there is the controller. The controller is a computer placed somewhere in the car. The controller just controls how the speed sensors, the pumps and the valve operate. ABS works by detecting hen brakes are applied to hard, and begins to turn the brakes on and off by taking away and re-applying the pressure on them. This stops the wheels on the cars from locking up, and most of the time stops the car from skidding.

Stefan’s Diaries: The Craving Chapter 27

There was nothing to indicate the passage of hours inside the windowless vault – not the barest suggestion of sunlight ever made its way under its doors. Days melted into weeks, maybe months. It felt as if an eternity had passed, and yet another stretched out endlessly before us. Lexi and I had stopped talking. Not out of anger or hopelessness, but just because we couldn't anymore. We didn't have enough strength to force ourselves to scream when we heard someone approach, much less get up and fight the stone that kept us buried. There was no more strength to fight the darkness, no strength to stand up. If I'd still required my heart to survive, I'm not sure I'd have had the strength to keep blood pumping through my veins. We lay silently next to each other. If anyone ever found us, a hundred years from then, we would look pathetic, like a sister and brother in some horrible fairy tale trapped in a witch's basement. Each passing second drained me of my Power. My eyes no longer parsed the darkness. The silence was absolute as sounds from the outside world faded into oblivion. All that I had left was my sense of touch – the feel of Lexi's waxy hand, the rough wood of the battered coffin next to me, the cool metal band of my useless ring. I felt almost human again, in the worst possible way. And as my Power retreated painfully, so with it went my immortality. I had never noticed its continual presence until it began to disappear, leaving meat and bone, brain and fluids, and taking away all that was supernatural about me with it. Except for my hunger. My vampire side reacted to starvation. My teeth ached and burned with need so badly that I would have shed tears if I'd had any. Blood weaseled its way into my every thought. I dreamed of how it had beaded up, jewel-like, on Callie's finger when she'd cut herself. How smoky my childhood crush, Clementine Haverford, had tasted going down. How, as my father lay dying on the floor of his study, his blood had spread out around him like greedy, searching fingers, staining everything in sight a dark, delicious red. In the end, everything comes back to blood. Vampires are nothing but hunger personified, designed expressly for the purpose of stealing blood from our victims. Our eyes compel them to trust us, our fangs rip open their veins, and our mouths drain them of their very life source. Blood†¦ Blood†¦ Blood†¦ Blood†¦ The word whispered to me over and over, like a song caught in one's head, filling every crevice of my brain and coating each memory with its tantalizing scent. And then a very familiar voice began to talk to me. â€Å"Hello, Stefan.† â€Å"Katherine?† I croaked, barely able to get the words out. I managed to turn my head just enough to see her sprawled voluptuously on a set of silk pillow cushions. She looked exactly as she had the night of the massacre, before they took her away and killed her. Beautiful and partially undressed, her pouty lips giving me a knowing smile. â€Å"Are you†¦ alive?† â€Å"Shhhh,† she said, leaning over to stroke my cheek. â€Å"You don't look well.† I closed my eyes as her intoxicating scent of lemon and ginger swept over me, so familiar and so real that I swooned. She must have fed recently because the heat from her skin burned in the cold tomb. â€Å"I wish I could help you,† she whispered, her lips close to mine. â€Å"Your. Fault,† I managed to breathe. â€Å"Oh, Stefan,† she scolded. â€Å"You may not have been as willing as your brother, but you didn't precisely object to my†¦ ministrations.† As if to emphasize her words, she leaned over and pressed her soft lips to my cheek. Again†¦ and again†¦ dragging them down my parched neck. Very, very delicately, she teased me, letting the tips of her fangs just puncture my skin. I moaned. My head spun. â€Å"But. You. Burned,† I rasped. â€Å"I saw the church.† â€Å"Do you wish me dead?† she asked, fire in her eyes. â€Å"Do you want me to burn, to collapse to the ground in a pile of ashes, simply because you can't have me all to yourself?† â€Å"No!† I protested, trying to push her off my neck. â€Å"Because you made me a monster†¦Ã¢â‚¬  Her laugh was light and melodic, like the wind chimes Mother had hung on the front porch of Veritas. â€Å"Monster? Really, Stefan, one day you will remember what you knew to be true back in New Orleans – that what I have given you is a gift, not a curse.† â€Å"You're as mad†¦ as†¦ Klaus†¦.† She sat back, alarm etching lines around her amber eyes. Her lower lip wobbled. â€Å"How do you know about K – ? â€Å" The crypt doors exploded into a thousand shards of stone and wood, as though shot through with a cannon. I covered my face, the light burning my eyes like acid. When I opened them again, Katherine was gone, and a blurry figure garbed in black wavered in the jagged doorway, haloed by the punishing light. â€Å"Klaus?† Lexi whispered in a terrified voice, clutching my hand. â€Å"Sorry to disappoint,† came a wry voice. â€Å"Damon!† I struggled to sit up. â€Å"Stefan, don't you think it's time you stopped just waiting around for your big brother to come and rescue you?† Without ceremony he reached in, grabbed my wrist, and flung me out of the crypt. I flew into the opposite wall and fell down into a heap on the marble floor. Damon was gentler with Lexi, though not by much. Another weightless corpse, she flopped against me, legs askew. Dust and shrapnel floated around us like fog. I blinked at the nondescript walls, trying to get my bearings. â€Å"Here,† Damon said, holding out a silver flask. â€Å"You're going to need it to escape.† I put my lips against the mouth of the vessel. Blood. Sweet, sweet, blood†¦ A voice in the back of my mind shouted that it was human blood, but I silenced it with a splash of heady liquid. I drank deeply, desperately, groaning when Damon grabbed the flask away from me. â€Å"Save some for the lady,† he said. Lexi drank greedily as well. Blood dripped down her chin and around her lips as she sucked hard and silently. Her skin, which had been drawn, pale and wrinkled as an old woman's, filled out and became pink and puffy. â€Å"Thanks, sailor,† she breathed. â€Å"I needed that.† Like a lamp filling a cellar with heat and light, I felt my own Power radiate through my limbs, returning my senses to what they were, imbuing my body with strength that I hadn't experienced since before I started eating only animals. As my vision cleared, I gasped. Behind Damon, a black-haired woman stood with one hand to her temple, the other gripped into a fist at her side. Her eyes were closed and her body shook with the slightest of tremors. It looked like she was in deep pain, being held in place while unknown tortures were applied to her mind and body. Margaret. And she wasn't alone. There was a prone figure in front of her, writhing in pain, and I realized with a jolt that Margaret wasn't being tortured – she was the one inflicting pain in another. In Lucius. In the super-vampire, so Powerful, yet still only a foot soldier of Klaus, the demon directly descended from hell. Lucius had murdered an entire family, captured me with ease, and caught Lexi like a troublesome mouse. The monster had his head in his hands and was screaming, terrible screams that seemed to send reverberations through the very chapel. â€Å"Is that Margaret?† I asked, dumbfounded. Damon pulled me up, propelled me toward the door. â€Å"We can't leave her!† â€Å"She'll be fine!† â€Å"But – â€Å" â€Å"Questions later. Running now.† And so, with one last look at the woman who had brought Hell itself to its knees, I ran away from the site of my imprisonment and out into moonlight.

Discuss the training requirements for Higher Level Teaching Assistants Essay

Higher level teaching assistants (HLTAs) have an increased level of responsibility. They usually undertake more complex tasks and tend to work more independently than other classroom-based staff. Under the direction of a teacher, they often plan, prepare and deliver learning activities to individual pupils, groups and (in the short term) whole classes. They also assess, record and report on pupils’ progress. They act as a special assistant for a specific subject (f.e. literacy, ICT, sign language), group (young children, teenagers, special needs, gifted and talented) or department and help develop support materials. In order to do this effectively, the HLTA must understand the aims, content, teaching strategies and intended outcomes. They likewise need to have a solid knowledge of the curriculum to make sure they teach to a high standard as well as a diverse portfolio of learning strategies and styles to enable each pupil to fulfil their potential.

CA eng 1st - Essay Example I believed that my father, being an illiterate man, was able to achieve enough respect in his life and I would be able to achieve the same by joining him eventually. I did not believe that education had anything to do with being successful and reputed. One day, when I was 16 years old, my father surprised me and told me that it was about time I came along and participated in a meeting with a supplier. He explained to me that this meeting was extremely important and it would be like a dream come true if the contract was signed. The contract was to export lights to another country and expand the business globally. I was extremely excited! I could see the enthusiasm in y father’s eye and he was hopeful that the deal would fall through. The meeting was with a man who had come from a foreign nation. He was unable to speak the national language and the issue started when he realized that my father was illiterate and he could not converse in English appropriately. The man seemed disappointed and he judged my father instantly as soon as he realized he wasn’t educated. Throughout the meeting I felt my father was constantly struggling to convince him to make the deal but he failed. The man had made up his mind. He did not want to do business with an illiterate businessman. I saw the grief and disappointment in my father’s eyes. His dreams had been shattered. He looked at me feeling helpless and asked us to leave. Seeing the helpless, disappointed look in his eyes made me decide instantly that I would not let my father down and I would fulfill his dream by being literate and moving his business forward. He would not be disappointed anymore and I would achieve in my life what this contemporary world requires out of business men. This was the moment of truth where I understood that in order to fulfill your dreams education plays a vital role. I stand here in front of you a proud man as

A Concise History of the Middle East Essay Example | Topics and Well Written Essays - 750 words - 1

A Concise History of the Middle East - Essay Example Oppression of Jews in Eastern Europe during the late 1800’s resulted in a mass emigration of Jewish refugees to Palestine some of whom formed Zionist movement, which was aimed at making Palestine an independent Jewish nation (Ellis, 1972) In 1917, Britain issued Balfour declaration which was seen as an attempt to support Jewish. The declaration however stated that Britain’s support for the creation of Jewish national home in Palestine without violating civil and religious rights of the non-Jewish communities. By the year 1923 Britain had received two mandates a provisional mandate over Palestine and another east of river Jordan Arabs apposed the idea of Jewish national home which lead to a Palestine, Arab nation movement in early 1930s over 100,000 Jewish refugees came to Palestine from nazi Germany and Poland) which made the Arabs organize a general uprising that paralyzed Palestine in the late 1930s. In 1939 British began to limit Jewish immigration and land purchases and it was to be done under Arabs approval only (Mendelsohn, 1989) During World War II, most Palestinian Arabs and Jews stopped their resistance to the British rule and joined the allied forces. After World War II Zionist wanted British to allow immigration of the holocaust survivors they therefore used force to stop Great Britain from limiting Jewish immigration into Palestine. The United Nations special commission on Palestine recommended that Palestine be divided into Arab state and Jewish state also Jerusalem to be put under international control. The UN general assembly adopted this plan on November 29 1947, which could lead to the birth of Israel. Arabs rejected the move and fighting broke immediately. Â  

Discuss the impact of raising minimum wages on minimum wage earners Essay

Discuss the impact of raising minimum wages on minimum wage earners and economy as a whole - Essay Example Increment of minimum wage has been a hotly debated issue not only by economists but also by the non-economist public (Neumark & Adams 6). On this issue, the non-economists have been largely pitted against the economists with the non-economists believing that raising minimum wage benefits employees and prevents employee exploitation by employers. On the other hand, economists are of the opinion that raising minimum wages actually hurt the very employees it is purported to help (Card & Krueger 20). This paper explores the effects of raising minimum wages for both the economy and minimum wage earners. Impacts of Raising Minimum Wages The first reason raising of minimum wages hurts the same people it is intended to help is that increasing these wages and creating laws that set them does not guarantee the public any more jobs. On the contrary, once minimum wages are increased, low-skilled workers are faced with the danger of being thrown out of the job market (Neumark & Adams 26). The rea son for this scenario is that employers will raise the skill requirements and the levels of competencies and experience and align them with the newly increased wages. In other words, employers are not willing to pay more for an employee if he or she does not increase or add value to a product in a manner commensurate with the wage increase (Card & Krueger 20). In the opinion of economists such as David Bradford of Princeton, raising minimum wages is tantamount to asking an employee to look for a job that would guarantee the said minimum wage (Neumark & Adams 15). Otherwise, such an employee may not find any job, depending on his level of skill. According to time-series data from decades of studies, it has been proved that raising minimum wages has the effect of reducing employment (American Enterprise Institute 3). This assertion is true if the rate of job losses in the current economy is anything to go by. According to current job estimates, a 10% increase in minimum wages could tr anslate into a decrease of between 1% and 2% in employment (American Enterprise Institute 4). Especially affected in this regard are young and unskilled workers, especially those from vulnerable and less academically and economically-endowed segments of the population. Besides increasing unemployment and job loss, minimum wage increment, especially the relevant laws, change workers’ systems of compensation. For instance, benefits such as free room and board, subsidized child care, on-the-job training, low-cost insurance, which are essential to low-waged and low-skilled worker compensations, are always negatively affected in cases of minimum wage increments. Employers have the tendency of controlling these benefits after minimum wage increments (American Enterprise Institute 4). In worse scenarios, when laws set minimum wages, some employers change full-time low-paying jobs into part-time high-paying jobs. Regrettably, there is rarely accompanying benefits such as reduced work ing hours. On-the-job training is the other aspect of low-wage employees that suffer reduction due to minimum wage increments (American Enterprise Institute 4). Hence, low-skilled workers lose their chance of improving their skills and opportunities to rise in rank. One benefit of reduced minimum wage, as opposed to increased minimum wage is that many employers prefer hiring unskilled workers and then

The description you have given is quite informative and I must agree that the systematic learning experience will definitely ensure the students that attend the class are well versed with the technique. Similar to what Billings and Halstead (2012), state in their text that learning objectives and checklist provide direction for students while practicing and learning the clinical skill, I found this to also apply to your learning experience design. It is true that may people do not consider self-administration of insulin to be a sensitive matter that needs care and hygienic conditions. You have mentioned that the skill will be learned over several sessions. Do you think that patients will be patient enough to attend all those sessions? Your post made me recall a sad situation I had in my childhood when a fellow student leg had to be amputated due to a wound infection that was not well dressed. He had stepped on a nail on his way from a camping site and after going to the nearby health Centre, the nurse who attended to him did not carry out the right procedure and soon after my friends leg was in a worse situation. It is therefore important for nurses to prioritize such a small topic such as would assessment with great interest.

Java Technology Essay Example | Topics and Well Written Essays - 750 words

Java Technology - Essay Example Sun systems first released the language to the public in 1995, with a promise of portability to run anywhere without many modifications. From this instance, Java quickly developed and was incorporated into many web browsers. The main goal of the developers was a language that was high performing, dynamic, threaded, robust, secure, and neutral in architecture, simple, familiar and object oriented. Various existing types of Java today have been developed with time since the language was developed. They include; JDK (1.0 and 1.1), J2SE (1.2, 1.3, 1.4 and 5.0), Java SE (6, 7 and 8). Due to the diversity in functionality and the sense of portability that has allowed the language to be put into practice in most Operating Systems developers, the language is now incorporated into almost all systems. Due to the presence of the Java virtual machine, the language is currently the most applicable for development of most web-based software as it allows independence in platform usage (portability). Being a high-level language, Java is used to make applications that can store data, transmit information, play games, develop android applications and do a myriad of other things. The major concept of Java is "Object oriented Programming." It is, therefore, necessary to learn the concepts of OOP in order to learn Java more easily. Above the OOP concepts, learning C or C++ would make one learn Java easily, considering that the language was developed from these languages. The de facto standard for Java implementation today is Oracle Corporation, which is the current owner of Sun Microsystems. This implementation has been widely accepted across various platforms such as Windows, Linux, Mac and Solaris. The implementation, which is mainly based on the Java SE platform. contains a "Java Runtime Environment" for end users and a "Java Development Kit for developers." There was an initial problem with the compiler that made programs developed in this language to run slower than

The Housing Market in the UK - Research Paper Example In other words, I am analyzing how the dependent variable is affected by the independent variable. My investigation is in B9. In my study, a dependent variable is a number of the bedroom while the independent variable is the price.   The data that I use in this report are first-hand data that I collected in the field. I visited over 100 houses of different types located in different places in the UK. My study covered different places in the UK. These include west London, hull city, North London and Westham Though I didn’t find the prices of some houses, I was able to find them on the agents websites. The agents post the photographs and information about the houses on their websites for the potential buyers from different places to see them. I also visited the agent’s offices to find out some information which was not available on the internet. I obtain questionnaires to obtain information from all the respondents that I met.   New homes have become more popular in the present age than ever. Developers have made efforts to create new homes that boast fabulous designs, energy saving and with excellent building qualities. Thousands of houses are now on sale by these new homeowners in the UK. A study has hence been carried out to obtain the general view of the housing market focusing on the housing prices, type and size of the house for sale.   The collected data is analyzed using different SPSS. The statistical aspects that the analysis looks into include mean, median, skewness, price kurtosis, variance and standard deviation of the collected information.     

Olympics Lottery Essay Example for Free

Olympics Lottery Essay The issue in which concerns the Active England programme is that the sale of national lottery tickets is gradually declining.  Research by Professor Ian Walker an Economist at the University of Warwick shows that lottery ticket sales are not influenced in anyway by the fact that the lottery supports good causes or the nature of those good causes. The dream of winning large sums of money is the only real driver of ticket sales. However, Professor Walkers research shows otherwise: The figure below shows the history of sales before, during (right in the middle of the graph) and after that controversy for the five main games. He says You dont need to be a trained statistician to see that the effects of rollovers in the lotto games and that there is a slight decline in sales for lotto over the period. So no support here that bad causes matter for sales. See graphs below:  Walker. I, 2004. Good Causes fail to Sell National Lottery Tickets [Online].

Accessed on 09.11.04  Measures taken by Sport England  Through this sudden decline in National Lottery sales, the above organisation have had to come up with strategic backup plans for alternate methods of funding and other ways of promoting their campaign and to make sure that they suddenly dont run out of money after promising bright and prosperous things to the nation. Sport England is possibly one of the National Lotterys largest good causes funding receiver and with the sales down by 2% from previous years, Sport England has to be careful with how they spend their money.  It is perhaps more difficult for voluntary and public sector clubs to receive funding through the thorough and detailed application process than before the cutbacks. The club must have a charter mark of high standard, a comprehensive code of conduct and practice for all parties involved and they must be able to prove that the money really will be able to change peoples lives. Whereas a number of years ago, it was rumoured that almost any club could receive funding if they wanted, and the nation saw money go to waste, which can no longer happen. With Sport England under fire by the media brought along a newly appointed chief executive, this created upset. Many peoples jobs were seen as not making enough contribution the cause and were subsequently axed.  Below is a shower of ideas in which Active England can consider to be successful in the future: Conclusion Throughout the portfolio, the key issues in which sport must adapt to have been identified.  With the National Lottery ticket sales slowly increasing again, funding for sports programmes should become readily available if suitably justified.

The Importance Of Effective Maintenance

The Importance Of Effective Maintenance Since the maintenance has significant impacts in industry, it has received a deep attention from the expert and practical maintenance. According to study, maintenance costs can represent from 15% to 40% of the costs of goods produced [x2]. Maintenance of process equipment is one of the inescapable tasks associated with the operation of industrial plants and until relatively recently, it was implemented either on a routine basis or after the failure of equipment. Attitudes are changing and now many organisations are adopting methods for identifying incipient faults, so that maintenance can be scheduled before there has been a failure, which would lead to loss of production and spoilage of raw material. Plants and different machine centres are assembled from a wide variety of mechanical and electrical equipment, which due to their very nature are subject to wear, corrosion, erosion and other forms of degradation [1]. It is widely accepted that intelligent, sensor based manufacturing is vital to achieve a high availability level of the sophisticated manufacturing systems in conjunction with high quality levels of manufactured components. Advanced sensor design, coupled with signal processing technologies, permits improved information about the process condition enabling process optimisation and control. It is not adequate to have information relating solely to the tool condition. Additional capabilities such as in process quality control and machine tool diagnostics are a requirement of the future, i.e. a shift from monitoring the tool condition to monitoring the process condition and the resulting part quality. [2] The use of mechanical vibration and acoustic emission signals for fault diagnosis in rotating machinery has grown significantly due to advances in the progress of digital signal processing algorithms and implementation techniques. The conventional diagnosis technology using acoustic an d vibration signals already exists in the form of techniques applying the time and frequency domain of signals, and analysing the difference of signals in the spectrum. Unfortunately, in some applications the performance is limited, such as when the signals caused by a damaged element are buried in background noise. [x3] In recent years, the possibility of obtaining more detailed information regarding the operation of process equipment by applying signal analysis techniques to conventional process measurements has, hitherto, been largely overlooked. This is because the principal purpose of the majority of process measurement systems is to provide a smooth signal for process control purposes. Therefore most process measurement systems are designed to produce a steady output signal, which is achieved by restricting the frequency response of the measurement system and thereby suppressing the noise component. [1] Signal transients are generally characterised by a short duration in time as compared to the observation interval. Research has shown that very important measurement information is often associated with the transients [1,2]. For example the vibration signals generated on a gearbox, the transients usually correspond to the local fault of the gear teeth, such as deformation, breakage and fracture. Thus analysing the transients of gearbox vibrations is useful for representing the characteristics of the gearbox health. However, it is not an easy task because the vibration measurements often carry heavy noise in the working environment, which could bury the essential vibration information of gears. Therefore, it is important and necessary to detect the transients with the machine health information in the very low signal-to-noise ratio conditions [3,4]. 1.2. Previous Work: This section contains information about the previous work that has been carried out with regards to condition monitoring and signal processing techniques. It also provides an outline of the different modern signal processing techniques used by researchers to identify faults with various machine components. 1.2.1 Machine tool A machine management system was developed at Cardiff University as a part of the MIRAM project (Machine Management for Increasing Reliability, Availability and Maintainability) that provides rapid fault diagnosis and allows the implementation of a predictive maintenance strategy [4]. This was used to extract data from the machine components by the sensors attached to it. The data processing methods implemented in the system allowed the characterization of normal and faulty behaviour of the machine component under investigation. An analysis has demonstrated the application of vibration monitoring using signal processing techniques such as Skewness, Standard deviation, RMS (Root Mean Square) and Kurtosis on the spindle system of machine tools. The results obtained from a signal after implementing kurtosis as a signal processing technique show a relatively high kurtosis value compared to other signals, which indicates a fault, associated with the spindle system. This analysis also describes the variations in the transients obtained from the coolant system of the machine tool. [5] Water treatment plant The research work conducted by a PhD student on the WRAP (Water Resources and Action Programme) test rig set-up at Cardiff University focuses on analysing the flow, pressure and pump speed request characteristics with respect to blockages induced on different valves. This analysis also studies the performance of the plant in relation to any leakages occurring in the system. Another analysis, which studies the performance of the same water filtration plant considers inducing 25 %, 50%, 75 % and 100 % blockages on the valves pre and post the pump. A fault dictionary created using a mathematical model approach was used to differentiate between the pre and post pump blockages and their degree of severities. [6] Use of modern signal processing techniques A review of modern signal processing techniques applicable to the analysis of signals whose frequency content is non-stationary has been studied in (R. Burnett, J.F. Watson*, S. Elder) [7]. Techniques like FFT (Fast Fourier Transform), STFT (Short-Time Fourier Transform) and Spectrogram have been discussed and compared using both test and actual data. Results are presented which identify the technique most appropriate for the task of fault detection in machine components under transient conditions [7]. A continuous wavelet transform (CWT) technique used for fault signal diagnosis in an internal combustion engine and its coolant system by using vibration signals has been studied by Wu Chen (2005) [8]. The advantages of using this technique for the characterization of transitory features of non-stationary signals have also been identified. Another journal contains a detailed study of the raw data obtained from physical machine parameters. It reviews the implementation of various modern signal processing and analysis techniques in time and frequency domain. Analysing signals in time domain for an initial analysis does not necessarily provide meaningful information due to background noise but transforming the signals into frequency domain provides detailed information. Further analysis shows how the vibration harmonics are linked to the identification of different types of machine faults. The harmonics within the signal categorising a component as faulty can be compared with the amplitude of those corresponding to components in a healthy condition to identify machines condition. [9] Aims of the project: The aims of the project are enumerated below: Study the characteristics and relevance of different modern signal processing techniques for the task of early fault detection in industrial machine components. Apply these modern signal processing techniques using Matlab to an archive of machine tool and water treatment plant signals obtained from the data acquisition system (DAS) and from a knowledge transfer program (KTP). Analyse these Matlab processed signals and identify the characteristics of the signal indicating a normal or faulty behaviour of the component under analysis. Chapter 2: Applications / Systems under study Wadkin V4-6 FMC: The Wadkin vertical machining centre was designed as a flexible manufacturing cell to perform operations on small to medium sized components. It comprises a fixed base, a single column, three axes of movements, an automatic tool changer, eight pallet loading stations and pallet transporter. Figure 2 shows a schematic of the machine tool centre. The Y-axis of the machine is formed by 4 hardened and ground steel slide-ways, which are fixed to the cast iron base of the machine. A table, which slides on low-friction strips can be moved to the left or right to form the X axis, by a motor. The Z-axis of the machine is formed by a cast iron column, which is bolted to the rear and upper surface of the base. This axis is moved and controlled in the same way as the X and Y axes. The head of the machine comprises the tool spindle, which is driven via a pair of pulleys, a belt and an electric motor. A tacho-generator attached to the motor is used to control the spindle speed. An encoder driven by a belt around the spindle is used to control the spindle position and orientation. Inside the spindle is a draw-bar with a spring (a stack of Belleville washers), which holds a tool in the spindle. A tool can be ejected from the spindle by activating a hydraulic cylinder above the spindle. This machining centre also consists of a tool transfer system and a 150 tool store is located to the right of the machine cell. The tool comprises 5 disks, attached to a vertical shaft, from which 30 tools can be hung. This shaft can be indexed to present a tool on each of the disk to the tool and horizontally between the spindle and the disks. On this mechanism is a pair of grippers, which holds a tool when being transport between the tool store and the spindle. [11] 2.1.1 Wadkin V4-6 Coolant system: Coolant systems are used in various application to pump liquids to cool and lubricate work pieces and cutting tools. The main objectives of the coolant system used for this application were to:- Prevent tool, work piece and machine components over heating. Increase tool life by reducing cutting forces. Improve surface finish Help clear swarf from the cutting area The cutter coolant system as shown in the schematic diagram Figure 1, comprises of two reservoirs each having a capacity of 39 litres located at either side of the machine base. The motor driven pump is controlled by means of a switch on the pendant control panel and can be switched off if coolant is not required for particular operations. The coolant pump motor on this machine cannot be switched on or off by means of programmed commands. Coolant is pumped via solenoid operated valves and a manually operated flow control/shut-off valve to the coolant outlets at the spindle nose. With the coolant pump motor running, coolant is turned on or off by SOV12 (flood coolant) and SOV51 (inducer coolant) which are energised or de-energised by programmed demands. Coolant flow is manually regulated by means of the flow control/shut-off tap located on the machine guard. Used cutter coolant drains back to the reservoirs where wire-mesh strainers prevent the ingress of large particles of swarf. A replaceable wire gauze filter is fitted to the pump inlet. The electrical system required to operate the pump motor and the two solenoids operated flow control valves comprises of three relays activated by command from the controller. These connect the flow control valve solenoids to the 110V AC supply and the pump motor to the 415V AC three phase supply. 2.1.2 Coolant systems component specifications: Table 1: Wadkin V4/6 Coolant systems component specifications Label as on diagram Component Description 1 Reservoir 2 tanks each of 39 litres capacity. Grating prevents ingress of large swarf 2 Filter Wire gauze filter attached to pump inlet 3 Pump / Motor Graham Precision pump, CPP 76. 3 phase AC motor, 2900 rpm, 1.1kw. Pump single stage peripheral impeller type. Maximum flow rate 11.6 lit/min. 4 Pressure relief valve Mechanical operated set at 4.8*10^5 N/m^2 5 Manual shut-off tap Manual tap 6 Flow control valves Solenoid operated Reason for analysing coolant pump signals: A large amount of data obtained from the Wadkin machine tool has already been grouped and processed into various charts and histograms for the ease of the analysis in previous research. The aim was to facilitate the research into machine tool condition monitoring system. Among the 160 recorded failures between a certain period of time, 84% fall within 18 pre-classified machine locations. Among these recorded failures coolant system being one of the 18 locations, ranks no. 3 in the failure frequency by machine location histogram [10]. Therefore applying modern signal processing techniques to these particular signals was considered to be a good approach to identify any faults within the component. Device(s) for acquiring signals: The raw data extracted from the coolant system were the pressure and flow signals. These signals were acquired by using flow and pressure transducers connected to the system and a data acquisition system was used to store these signals in a database for further analysis. The Kobold flow meters and switches types VKM have a spring-loaded float, which slides within a cylindrical measuring tube and has an integral orifice. This type of flow meter is a low cost flow meter and switch, which fully compensates for viscosity and to large extent for density even with very low flows. Wadkin V4/6 Spindle system: He hardened steel spindle is supported in the head casting by two pairs of pre-loaded angular contact bearings. The spindle is driven by a D.C. electric motor via fixed pulleys and a wide poly-vee belt, and has a speed range of 40-5000 rev / min. Figure 3 shows the schematic diagram of the spindle drive system. The analyses and modelling of this is very similar to the feed drive mechanism, however it does not include any linear movement and is subjected to a distributing torque proportional to cutting force components. [12] The spindle, which is fastened into the head of the machine tool, is shown in figure 9.1. It has two bearings at both the top and bottom of the shaft, together with seals to retain the grease either side of each set of bearings. On the top of the spindle is a pulley, which is driven via poly-vee belt ad a pulley attached to the spindle motor, which is shown in figure 9.2. To measure the speed of the spindle and its orientation at low speeds, an incremental encoder is positioned towards the side of the spindle. This is driven from a pulley fixed to the spindle, toothed belt and a pulley attached to the encoder as shown in figure 9.3. In figure 9.4 and exploded view of the drawbar, which is fitted into the spindle, is shown. It uses a stack of Billeville washers, which are used to draw a tool into the spindles taper. Reason for analysing spindle vibration signals: The bearings in the spindle system can fail fue to overload, misalignment, insufficient lubrication and assembly defects. Condition monitoring of these bearing is therefore very critical to the machining process. Spindle systems component specification: Device(s) for acquiring signals: The vibrations from main spindle bearings were measured by using two accelerometers mounted on the head of the machine tool as shown in figure 4. Two ENDEVCO model 5216-100 series piezoelectric accelerometers were used, which are designed specifically for vibration measurement in rugged environments of industrial machinery. These type of accelerometers have very wide dynamic range and an extremely low noise floor. [12] Data Acquisition System (DAS): A flexible and generically applicable data acquisition system has been developed at Cardiff University for the machine tool condition monitoring. This system can be viewed as a data logger associated to one or more sensors. Its flexibility allows the addition of any data logging software, hardware or sensor(s) to be linked for the analysis of different machine components when required. The DAS is controlled by a relational database management system (DBMS). The DMBS provides a user interface to specify the details of the condition monitoring tests to be performed [13]. 2.2 Water treatment plant (WRAP rig): 2.2.1 Background: The WRAP (Water and Resources Action Program) rig is a test rig set-up at Cardiff University used for research purposes. It is housed in a small container for it to be transported easily to plants or sites for demonstration purposes. The rig is designed to allow a direct performance comparison between two different types of filtration media. This rig was specifically used to demonstrate the performance of Recycled Glass Media (RGM) compared to the conventional filtration media such as sand. In previous research this rig has been used to process wash down water from a dairy production line while its sister rigs were used for different applications such as the removal of bio fouling and other wastes. The figure below shows the WRAP rig along with the individual constituents that make up the rig. Functionality of the rig: This explanation of the rig is based on the detailed piping and instrumentation diagram of the rig shown in figure x. The rig consists of four 6-staged impeller centrifugal pumps P1, P2, P3 and P4 as indicated in the diagram with P1 being disconnected as there was no external open reservoir in operation. Pumps P2 and P3 transfer unprocessed liquor to filters F1 and F2 from tank T1. This relationship / process can be altered using valves V8, V9 and V10 for operational flexibility if required. The two pneumatically actuated diaphragm valves V5A and V5B, which are controlled by the programmable logic controller (PLC) enables the flow to be selected from either the unprocessed effluent stream entering F1 or F2. The PID (Proportional Integral Derivative) loop also maintains the flow rate into each filter at a pre-programmed set point. The flow transmitters FT1 and FT2 were controlled to provide a 0-10V output to the invertors, which controlled pumps P2 and P3. This was achieved via the PID loop algorithm in the PLC. The analysis of this report only studies a small part of the WRAP rig, which is shown in figure x below. Two Cylon UC32.24 PLCs networked using a proprietary serial protocol controlled the system. These in turn were networked to a communications module, which contained a GSM modem and features two RS232 ports for connection to external devices. Chemwatch, Cylons proprietary SCADA system was used for three original operation of the rig. The system was configured to display two process mimic screens that showed real time values of the various sensor readings. A number of alarm and control screens were also present allowing a privileged operator to alter alarm thresholds, control parameters and manually override system components such as pumps.

Impact Of Zakat In Society Theology Religion Essay

Impact Of Zakat In Society Theology Religion Essay The socket has been introduced in pre-colonial Malaysia .Before the British colonial Malaysia, the village in the country, as in other parts of the world developed through land settlement or colonization. One of the popular methods was the collective Pondok system, which was particularly common in the Muda Region of Kedah. By this system, a group of settlers would gather around and a person who is well -versed in Islamic Knowledge or who had already established himself as a religious teacher .After the they found a suitable place , they will build their Pondok (huts) around a Madras; a religious center for worship as well as teaching. In the case where the group has been established, they would invite a religious teacher from elsewhere to set up a Madras among them .This religious teacher was also the Imam of the community, in the sense that he led five prayers daily in the mosque or madsarah. The group of peasant will be going out to open land around the clusters of their Pondok, leaving their children to the teacher for religious education at day time. For those wives who are unable to work with their spouse in the land also will obtained religious instruction from the teacher. The peasants will receive religious at least one or twice a week and longer on Friday because it was a day of rest. They will spend more time in the mosque than the field. As an appreciation for the service provided by the teacher, the peasants usually will collectively clear a piece of land and cultivate if for the teacher. Slowly, as the land become more productive and the production level of each peasant family exceeds the nisab of 480 Gantang  [1]  for each harvesting; the peasant family would pay skate at their 10 % of the gross yield of the paddy. According to Afifudin, those early days all the skate form a specific group in the Pondok system would go to the teacher. If a group of 50 sacked paying peasants would contribute a minimum of 2400 Gantang each year .As time goes by, the wealth of the teacher can be accumulated. The teacher can use the socket for the expansion of Madras. During the colonial period in Malaysia especially Kelantan, Zakat was administered by imam, who is the local religious leader managed the Zakat collection and supervised by the division of inherited party. In order to finance the intensified activities, the state required imams to surrender part of the Zakat they collected at the village level. However, this method is only partially successful due to the British regime replaced Grahmans, the Islamic administration .The Grahman took charge of civil administration, he divested the imams of their civil function .which were transfer to the headman (ketua kampong). According to secret institution in Malaysia .During British Colonial Period, The segregation between religions, custom and temporal matters took place during this period. All Islamic and Malay customs related matters were administered by a special body known as Majlis Agama Islam Negeri (MAIN). Other than that, the rest came under the purview of the British civil and criminal law system (Matters associated with socket were administered by MAIN. Accordingly, in Zakat Satu Tinjauan, Kelantan was the first state to establish the body which later became a model to other Malay States. Under this model, the Imam (spiritual leader) has been empowered to govern skate related matters and a portion of Zakat collection would be delivered to the state government as a financial resource for Islamic affairs. That was how the administration of soaked developed until today which remain under the supervision of State Islamic Councils. After the independence of Malaysia, New Economic Policy has been introduced. The Zakat fund is use for investment purpose .In the early 1970s ,the minister of National and Rural Development, Encik Ghaffae Baba, who was also the chairman of Mara ,urged all the state Religious Councils to invested substantial portion of their money (mostly derived from the collection of Zakat) in Amanah Saham Mara .The objective is to eliminate the income gap between the ethnic group in Malaysia, especially the Muslim and Chinese. DEFINATION AND CONCEPT In the Islamic world, Muslims are required to give compulsory charity with determined purpose and established rules. This compulsory charity is known as Zakat. Zakat is one of the five fundamental pillars of Islam; it stands as the third pillar of Islam, just after Salat, the daily ritual prayer. Allah has mentioned Zakat about twenty times in the Holy Quran combined with Salat.   Basically, Zakat, or Zakat al-Mal, means obligatory alms or alms upon wealth. Alms is a gift of money, clothes or food, it is equivalent to charity and is a type of donation. Moreover, Zakat is literally means to be clear, to grow, to increase. It comes from the root letter za, kaf, ya which consists of few meanings, which are to be clean, to pay the obligatory charity, to be pure innocent, to be better in purity and to praise oneself, to justify. All of these have been included in the Quran and explain all of these things. In addition, Zakat can be defined as the transferring ownership of an amount of material wealth specified by the Lawgiver to a poor Muslim who is neither Hashimi nor their client, without material benefit returning to the giver in any way, for the sake of Allah Most High. [Tumurtashi, Tanwir al-Absar] Hashimi in here means those from the family of the Prophet (Allah bless him and give him peace). Besides, the term Zakat and sadaqah are often used interchangeably in the Quran and Sunnah, where sadaqah also means charity. However, Zakat refers to obligatory charity and sadaqah refers to voluntary charity. Zakat can be categorized into two types; there are Zakat-ul-Maal (Zakat on the wealth) and Zakat-ul-Fitr (Zakat on the individual). It is recommended to every Muslim to pay sadaqah after paid the two types of Zakat. Other than that, Allah has prescribed Zakat as a duty to Allah, upon every wealthy individual. Every Muslim also has nisab, which is a designated minimal amount of wealth for the full cycle of a lunar year must, as a matter of worship, satisfy the duty of Zakat-Charity. This charity is to cleanse or purify the individuals wealth. Unlike charity, Zakat can only give to Muslim; it is not valid to give Zakat to a non-Muslim. THE OBJECTIVE OF ZAKAT The primary objective of Zakat is to elevate the spirit of human being above the material acquisition. Consequently, Islam does not view the Zakat payer as a mere of sore of funds, but as a person who always needs purification and cleansing, both spiritually and materially .The prophet (p) summaries this purpose in the ayat ,sadaqa from heir wealth by which you might purify and cleanse them. Zakat, when paid out of submission to the command of Allah, is a mean of purifying the soul of a Muslim from greed and miserliness. The vices of selfishness and greed must be controlled in order for human beings to elevate their spirits, to succeed in their social relations in his life, and gain admittance to paradise .Allah Almighty says, Truly man is niggardly! (17:100) and But people are prone to selfish greed.)Zakat is a purifier that trains Muslims to give and spend selflessly .It liberates their souls from the love of wealth and slavery to materials gains and acquisitions. On top of that, Zakat is a mean of training Muslims on virtues of generosity as much as it is a means of purification from greed .Being paid in repetitive pattern year after year, regular Zakat as well as Zakat al-fitr train Muslims to give and spend for charitable purpose. The Quran describes believers as the righteous who have the virtue of spending for good reasons. The very second sura of the Quran begins, Alif .Lam .Mim.That is the Book with no doubt .In it is guidance for the god-fearing: those who believe in Unseen and establish the prayer and give of what we have provided for them.This exhortation is reiterated many times in the Quran ,such as Those who give away their wealth by night and by day ,secretly and openly ,: Those who give in times of both ease and hardship and The steadfast ,the truthful ,the obedient ,the givers ,and those who seek forgiveness before dawn. Also, once a person is trained to spend on public interests and to give to his brethren out of his own wealth, he is most likely to be freed from any urge to transgress on other peoples wealth and possessions. Besides that, Zakat trains people to acquire divine characteristic. If man purified of miserliness and greed and becomes accustomed to the habit of giving and spending, his soul is elevated above low human trait of covetousness, Truly man is niggardly! (17:100) and aspire to the height of Divine perfection, since one of the characteristic of Allah is absolute and unlimited mercy, powers, theoretical and practical .Allah obliges Zakat in order to perfect human souls in graciousness to other people ,as the prophet says, Train yourselves to attributes of Allah. This encouragement to spend through Zakat and voluntary charity resulted with time, you in the emergence of charitable trusts all over Muslim world, trusts devoted not only to helping the poor and needy but to all causes for human beings as well as animals. In addition, Zakat is to shows expression of thankfulness to Allah .Gratitude and thankfulness are among the best characteristics of human beings. Zakat is an expression of thankfulness to Allah for the bounties .He gives on us .Allah, says al-Ghazali, and has gives on human spiritual and materials bounties. Prayers and other acts of physical worship express gratitude for the blessing of creation, while Zakat and other acts of donator worship express gratitude for the material blessings of Allah .The concept that Zakat is thanks Allah for His bounties is s widespread and deeply rooted in the consciousness of Muslims that it is common to say that one must give Zakat in thanks for the grace of sight, hearing, health, knowledge, etc. Also, Zakat stimulates personality growth in those who pay it .Through helping others overcome their financial difficulties, Zakat payers are enriched by feelings of self-worth and fulfillment. Zakat also helps offer the payers self to others and grow through helping them and gives the payer a noble sense of victory over his base desires and material drives-over his owns shaytan. Last but not least, Zakat is to purify wealth. This is because Zakat is a right to the poor, not paying it means keeping something that belongs to others intermingled worth ones wealth and this brings Allahs wrath on the whole wealth. The Prophet (p) says, If you pay Zakat on your wealth, you have taken away its evil. IMPACT OF ZAKAT IN SOCIETY Undeniable, the concept of Zakat is the cornerstone in Islamic finance and economic system. Zakat is a compulsory charity that every Muslim must pay and to help the poor people. This has causes Zakat play an important role in the society, especially the Muslims society. Below are several impacts brought by Zakat system? The Zakat system helps to make sure the societys wealth circulation is in a fair and clean condition. Due to the wealth people must pay Zakat to the poor, the wealth will not become too rich whereas the poor will not become poorer. Definitely, there are some restrictions in order to choose the Zakat recipients, the restrictions can make sure those who receive the Zakat is with a reasonable and acceptable reason. In this case, Zakat has becomes the duty of wealth people, just like a compulsory charity must done by wealth people. But, the percentage of Zakat paid is depends on the wealth of an individual, it is not a system that forces people to pay a certain amount, but is require Muslims to pay their minimum amount according to their wealth which is affordable. Zakat also allows an individual to purify and grow his wealth. Man is naturally greedy and always want more and more to fulfil their unlimited utility. Zakat, with the obligatory charity, require Muslims to do charity. This process might make the people to think of others and come out from the race of personal interests. It has help to cleanse the selfishness of an individual where someone may extend his financial in order to help more poor people and those in need. The Holy Quran also has mentioned that And whose is saved from his own avarice such are they who are successful. With more and more individual with this personality can maintain the peacefulness of the society and becomes the role model for the next generation. Besides, Zakat system has helped to reduce the poverty problem in many countries. The main reason for poverty in any society is the concentration of wealth is limited to a very few people in a particular country. The introduction of Zakat system is actually for the purpose of this root cause of poverty. If everyone will need to pay Zakat, no poor or the unfortunate would have to involve in the begging. As the wealth is distributes to the poor, the poor will have the ability to continue struggling for their lives. In addition, Islam has prohibited the poor or needy from stretching hand before others. In the economic perspective, Zakat has also help to increase the production volume. When the Zakat has distributed to the poor and people in need, they would spend the money to satisfy their personal needs or basic needs, which then results in the increase of production volume. A rich individual however, will not need to spend too much money in order to fulfil their needs in life. Even the one wants to spend much, it will not more than a group of poorer spending money for basic needs. Moreover, the increase in production volume will led to the rise of several economic activities. In order to support the increased production, the economy would generate more jobs and more working opportunities which causes the unemployment level tends to reduce with the growth of economy in overall. The rise of job opportunities will then generates more demand of goods and services and more space for additional investment. And, finally, the growth cycle will lead to a balanced economic growth. Other than that, the Zakat system also will increase the overall savings of people, although with the concept of discouraging of over storage of money for an individual. Consequently, the income level of a society also has increased. All of these economic activities will led to the decrease in probability of economic recession. As the Zakat system is used to balance the wealth between the rich and poor, the chance of recession can be reduced. The impact brought by Zakat towards economic has improved the living standard of society, the inequality and poverty problem reduced and helped to decrease the crime rate and any other social evil that would harm the society. This is how the Zakat system makes a difference towards the society. TYPES OF ZAKAT Zakat is divided into several types: Zakat of Income Zakat of Savings Zakat of Business Zakat of KWSP/LTAT Zakat of Share Zakat of Livestock Zakat of Gold and Silver Zakat of Crops Zakat of Income Extra payment received by an individual from their employer or individual itself in the form of physical energy or physically or professional employment for specific day, month and yearly also been required to pay Zakat. Employment income includes: The annual salary Other allowances Unpaid wages Other remuneration such as bonuses, etc. Method of Calculation First Method Using gross income (without deduction) 2.5% on gross income per year. Example: Total gross income per year: RM 25,000.00 Amount of Zakat (2.5%): RM 625.00 Monthly Payment: RM 625.00 /12 = RM 52.08 Second Method Using the net income (Income year less allowable expenses per year) x 2.5% Expenses allowed deduction (per year): -:- Self: RM 8,000.00 Wife: RM 5,000.00 Children: RM 1,000.00 KWSP: 11% from gross income workers Parents Contribution: RM (amount given) per month x 12 months Contributions to organizations that pay the Zakat (for example: Lembaga Tabung Haji, Takaful) Zakat of Savings Contribution of workers and employers to KWSP People Provident Fund , Soldiers Provident Fund (LTAT) are also required to pay Zakat as the concept is similar to savings but the different is savings of KWSP and LTAT could not be withdraws anytime where never they like and it is subject the rules. Fixed Deposit Fixed deposit of RM 100,000 was kept for a year without the excluded (assumed nisab charity at that RM 9430.00) Then charity is required to produce are: RM 100,000 x 2.5% = RM 2.500 Regular Deposit Method of Calculation (Duration haul is January 5, 1999 until February 7, 2000) (Assuming nisab of charity at that RM 3,323.50) So Zakat are: (Balances with lower interest bank refused WITH) X 2.5% (RM 9,115.00 RM 115.00) x 2.5% = RM 225.00 Zakat of Business Zakat been given out by Sole Prop irate, Partnership, Cooperative Society, Societies and Organization which had reached one year and the time limit. Method of Calculations [(Current Assets Current Liability) + Coordination x Percentage of Muslims Share x ZAKAT ABILITY (2.5 %)]. Zakat of KWSP Contributions of employees and employers into the Employees Provident Fund (EPF), Lembaga Tabung Angkatan Army (LTAT),or the like imposed zakat as conceptually the same as saving money, but with the difference amount of savings, LTAT and so on shall not be issued at anytime because and subject to regulations that is fixed. Method of calculation First Method 2.5% of the contribution that issued once money issued. Second Method 2.5% of contribution every employee is based on the annual statement Zakat of Shares Zakat which is given out for investment which has reached its time limit and minimum value. Methed of Calculation 2.5 % the value of lowest share share which is own for one year minus for shared borrowed. If the lowest value is not determined, use the value beginning early in the year or in the year or whichever is the lowest. For shareholders which must be owned by investors. Muslims in the long term to gain control a company or firm so his payment for Zakat will be based on the calculations that it will not affect the importance of other Muslims to get hold of the company. If any of the owners shares has not reached one year, but the whole property being changed for a number of time for one year from shares to cash and vice versa, so use the lowest value with the mixture of money and shares, shares with basic to count Zakat multiply 2.5 %. Zakat of Livestock Livestock Zakat is property Zakat that required to be taken out in perfect the conditions. Domestic animal that obliged to pay Zakat is among them such as goat, cattle, camel, sheep, and buffalo. Prophet S.A.W said From Muaz Ibnu Jabal, had said, RasulullahS.A.W was sending me to Yaman and ask me to collect zakat from each of 30 cows, 1 lamb musinnah (1 female cattle aged up to 3 years ) and every 30 cows, tabi or tabiah ( 1 male or female cattle aged up to 2 years). The livestock that we would like to give a Zakat must be perfect and no defects such as missing the foot or hand and so on. COWS/BUFFALOES Quantities Zakat Amount / Sex 30-39 tail 1 tail, age 1 year / male 40-59 tail 1 tail, age 2 year / female 60-69 tail 2 tail, age 1 year / male 70-79 tail 1 tail, age 1 year / male and 2 tail, age 2 year / male 80-89 tail 2 tail, age 2 year / female 90-99 tail 3 tail, age 1 year / male 100-109 tail 1 tail, age 2 year / female and 2 tail, age 1 year / male 110-119 tail 2 tail, age 2 year / female and 1 tail, age 1 year / male 120 tail above tail, age 2 year / female and 3 tail, age 1 year / male GOATS Quantities Zakat Amount / Sex 40-120 tail 1 tail, age 2 year / male or female 121-200 tail 2 tail, age 2 year / male or female 201-399 tail 3 tail, age 2 year / male or female Subsequent additions : Every of 100 tail plus plus 1 tail, age 2 year / male or female SHEEP Quantities Zakat Amount / Sex 40-120 tail 1 tail, age 1 year/ male @ female 121-200 tail 2 tail , age 1 year / male @ female 201-399 tail 3 tail, age 1 year/ male @ female Subsequent additions : every 100 tail Increased by 1 tail, age 1 year / male @ female. Zakat of Silver and Gold Gold and silver is a mineral that is required to charity. This is because these metals are very useful as it uses an exchange value of all things. As for other jewelry than gold and silver like diamond, pearl, silk, copper, are not obligatory Zakat on it. Nisab Zakat gold used = 200gram Gold Zakat Nisab unused = 85gram Zakat of Crops Zakat for basic food after it has reached the stage of satisfaction for the state which is 363 gantang / 1300 kg like paddy, wheat, cereals and so on. Method of Calculation First Method Cereals and fruits which used by people energy, animals and machines will use a lot of expenditure and so that the Zakat is 10 % or 1/10 Second Method Cereals and fruits depend on rain water, so Zakat is 5 % or 1/20 Third Method Cereals and fruits depends both as above method, so Zakat is 7.5 % ZAKAT PAYMENT When Does Zakat Become Obligation Only the wealth of Muslims is imposing to Zakat, it is not required from non-Muslim. First, this is because Zakat is one of the Pillar of Islam; it cant expect any disbeliever to pay it. Second, Islam is one of religion which is prohibiting any action that enforce others accept Islam as ones religion. In additional, if people just adapt them to Islam they should not be asked any past due of Zakat (the period of disbelief). According to the Shariah, Zakat is an obligatory for any Muslim who is: Mature Only major subject to the Zakat, qualify as a Zakat payer. Due to the lack of legal capacity, minor are not under a fard obligation to perform acts of ibadah. They are exempt from paying Zakat by using reason they deficiency of legal capacity. Sane As a Zakat payer, he should be sane. Before a child reaches mature, he considers as insane. He is exempt from the payment of Zakat during that period and liability of Zakat is start calculate when he get back his sanity. For another example, although the person was sane at the time of maturity but after that he becomes insanity. This person also exempts Zakat for the period his insanity. The liability of Zakat is calculated from the date of recovery of sanity. On the other hand, if the person only insanity of a part of the year, then his liability for Zakat of that year is calculated, no exempt. Free Owns the minimum (nizab) As a Zakat payer, he must meet all these four conditions. If one condition is not met, he doesnt have an obligation for the payment of Zakat. Besides, even a child, an orphan, or a mentally retarded person is exempt from Zakat payment but they are required to pay on their behalf. Last, if a person died without pay the Zakat was due, Zakat will take from the estate of a deceased person. ZAKAT DISTRIBUTION Categories Where Zakat Can Be Spent Zakat is only paid to an individual who is really needed and deserve. In the Quran, Allah (swt) says that: Zakat is for the poor and the needy and those who are in charge thereof, those whose hearts are to be reconciled; and to free those bondages, and to help those burned by debt, and for expenditure in the way of Allah, and for the wayfarer. This is an obligation from Allah. Allah is All- Knowing, All- Wise. (9:60) According to this, Zakat only can pay under eight categories. There are: The poor and the needy The main objective of Zakat is to reduce or mitigate poverty and destitution in social. The way to achieve it is taken from the rich and rendered to the poor. Actually, people who are poor and need is different. People whose are categories as poor when they are in need but due to modesty and self-respect, they are not begging from others. People who are in need and they are submitted in begging from others are classified as people who are needy. A person has become poor and needy mostly is because they are shortage in their income, they cannot fulfil the essential needs, and they are totally poverty. Besides, poor and need also includes those are physical disability, old age, or accidental circumstances. According to Al-Qaradawi, full- time students can be in needy situation when they are continuing their education. Workers in Zakat administration A person who collects and distributes Zakat is the third category of Zakat recipients. Based on Al- Qaradawi, Zakat collection and administration is the function of an organized body paid employees. Workers can receive Zakat as a compensation for their works regardless they are poor or not. Besides, this compensation must compete with the market value of their labour. Those whose hearts are being reconciled Five types of people involved in this category, there are: An individual who is close to become Muslim or whose clans may become Muslim. An individual who may do evil or harm to Muslim. Giving a Zakat to those people will prohibit them to do it. An individual who has just become Muslim, Zakat will help them to be engaged with Islam An individual who has a positive influence on Muslim. A Muslim who is expected to defend their Muslim land against attract from other. This happens especially when they are living on the boarder of a Muslim country. Muslim whose influence is needed in the process of collecting Zakat in order to convince individuals whose will not pay their Zakat. This action can avoid having fought between government and whose reject in Zakat payment. According to some jurists, such as Hanafis and Malikis, this category is not exist since the death of the Prophet but Al-Qaradawi and Mawdudi disagree with it, they state that Zakat recipients in this category have not stopped, but the payment only can make by the Islamic state, not by individual Zakat payers. Emancipation of slaves Contracted salves can use Zakat to pay his master in order to gain his freedom. Allah orders Muslims must show respect and give to give slaves who wish his contract is freeing. Besides, Allah also orders master to help his own slaves become freedom if they demand it. Allah says, If any slaves you own desire to make a contract to free themselves, write it for them if you know of good in them some of the wealth Allah has given you. Those burned in debt. According to the Hanafi School, a person is included in this category when he does not have enough wealth to serve his debt. The debts arise from consumer expenditure; it includes medical bills, building a house for personal residence, and marriage. Besides, victims those hit by natural disasters or accident and force them must borrow from other in order to continue their basic life also includes in this category. Zakat also consider as a high quality insurance against the financial effect from natural disasters or accidents. Before applying the Zakat, four conditions must be met, they are: The debtor must be in need of financial facilitating. A person who can cover his debt with his own wealth can not apply from Zakat. Besides, people who do not have sufficient wealth but they still can serve his debt with the income is eligible for Zakat. This condition shows Zakat is not only for a debtor who is totally destitute. Zakat may pay with difference depend on the level amount of debt against the available wealth of the debtor. The debt must come from Islamically lawful activity, for example borrowing in order to support the family. Loans are used for activities those are prohibited by Islam cannot be paid by Zakat. These activities include consumptions of alcoholic beverages and over-spending on lawful items. The main reason Zakat cannot be used to pay in these activities is to stop other to do this sin activities. The debt must be due immediately. Different scholar has a different idea of this condition. Some scholars approve that if the debt is due after one year, the debtor cannot get Zakat to pay it. Some disapprove of this; they argue that Zakat can give help to debtors regardless of the due date of the loans. One can be confirming is obligations owed to God are excluded in this category. The debt should by reason of other human beings. For example, obligation to Allah is excluded in this category. Obligation to Allah can be due Zakat and compensation for breaking a certain condition in Shariah. Expenditure in the way of Allah. After concluding the views of the Hanafi, Maliki, Shafii, and Hanbali, three points are agreed with them. There are: Jihad considers a part of this category. The fighter who fighting for the sake of Allah is lawful to receive Zakat. However the equipment and arms to fight is not agreed with some scholar. Public works such as building school, mosques, highways and roads, and irrigation canals is not qualified to receive Zakat. Four schools say that this public works have other funds to pay it such as fay and kharaj. Wayfarer Majority jurists believe that someone who just desire and just start travelling isnt classified in this category. This is because term Ibn as-sabil is meant someone on the road and a person who starts and desire travelling is still staying at home. Besides, a person considers as travellers will cut off his financial means at home. That means no income for him when he is travelling. A person who is desire for travel hasnt cut off his financial means yet. The wayfarer is one of a category can receive Zakat because of several reasons which are encouraged by the Quran: Travelling for purpose work and opportunity. Travelling can seek more knowledge and ponder on the signs of Allah in the world and on His animal and human communities. Travel can for the purpose of jihad in the Way of Allah Travel because of to attend the pilgrimage to the Sacred House of Allah. Categories Who Can Not Receive Zakat According to Yusuf al-Qardawi (1999), there are several categories of people who is cannot receive Zakat. These categories are: The rich people Zakat has purposed to reduce poverty and destitution in social. In order to achieve it, Zakat will be taken from the rich and rendered to the poor. If Zakat is given to the rich, th

Comparing Four Electronic Tuners Essay -- Compare Contrast Comparison

Comparing Four Electronic Tuners One in every 10,000 Unites States citizens are born with what doctors refer to as perfect pitch and those born with this ability are able to accurately identify any note they hear. In other words, a person with pitch perfect has built-in tonal memory that allows them to correctly label pitches. Unfortunately, most musicians lack this ability, and they work very hard to develop what is known as relative pitch. Relative pitch refers to a musician’s ability to identify pitches in relation to one or two memorized pitches. Therefore a person with relative pitch might memorize what an â€Å"A† sounds like and use that pitch as a marker to identify additional pitches heard. Unlike perfect pitch, relative pitch is not instantaneous, and it can become compromised if the musician does not continue to practice the skill. Fortunately, technology is making it far easier for musicians to strive for the perfection expected of live music today, and where once musicians had to rel y entirely on their own senses to identify and play pitches in tune, devices known as tuners are helping to correct and develop the occasionally unreliable senses of humans. A tuner is simply electronic device that can except an audio input and translate it into some type of visual aid for the musician. The most common displays consist of either a strobe or some sort of LED/LCD display that indicates the pitch played and whether or not the pitch is accurate. The accuracy of the pitch is measured in cents. For instance if a ‘C’ is played into the tuner, twenty cents sharp would mean that on a scale of 0 – 100, the pitch being played is 20/100 or 1/5 higher than what is considered to be an accurate ‘C’. This also implies that the... ...ge where as the Seiko and Korg have no such guarantees. When evaluated on sensitivity, the Peterson is the clear winner of the four. Finally, it is difficult to objectively rate the value of each tuner. Certain features are more important and useful to some individuals while not to others. Therefore what may seem like a reasonable price to one person may seem unreasonable to another. However, it seems that the Sabine is the best product for the price it is being sold at ($29.99). Despite the fact that it is the only tuner that has a sub 8-octave range, it features a built-in metronome which when bought separately would most likely cost $35.00 (price of a metronome with comparable features). Therefore the recommended personal tuner is the Sabine tuner/metronome. For supplemental photos, tables, and graphs, please see the accompanying PowerPoint slideshow.

Psycho, The Movie Essay -- essays research papers

Psycho (1960) Perhaps no other film changed so drastically Hollywood's perception of the horror film as did PSYCHO. More surprising is the fact that this still unnerving horror classic was directed by Alfred Hitchcock, a filmmaker who never relied upon shock values until this film. Here Hitchcock indulged in nudity, bloodbaths, necrophilia, transvestism, schizophrenia, and a host of other taboos and got away with it, simply because he was Hitchcock. The great director clouded his intent and motives by reportedly stating that the entire film was nothing more than one huge joke. No one laughed. Instead they cringed in their seats, waiting for the next assault on their senses. The violence and bloodletting of PSYCHO may look tame to those who have grown up on Jason and Freddy Krueger, but no one had ever seen anything like it in 1960. Inspired by the life of the demented, cannibalistic Wisconsin killer Ed Gein (whose heinous acts would also inspire THE TEXAS CHAINSAW MASSACRE, 1974 and DERANGED, 1974), PSYCHO is probably Hitchcock's most gruesome and dark film. Its importance to its genre cannot be overestimated. PSYCHO's enduring influence comes not only from the Norman Bates character (who has since been reincarnated in a staggering variety of forms), but also from the psychological themes Hitchcock develops. Enhancing the sustained fright of this film are an excellent cast, from which the director coaxes extraordinary performances, and Bernard Herrmann's chilling score. Especially effective is the composer's so-called "murder music," high-pitched screeching sounds that flash across the viewer's consciousness as quickly as the killer's deadly knife. Bernard Herrmann achieved this effect by having a group of violinists frantically saw the same notes over and over again. Hitchcock really shocked Paramount when he demanded that he be allowed to film the sleazy, sensational novel that Robert Bloch based on the Gein killings. Bloch's subject matter and characters were a great departure from the sophisticated homicide and refined characters usually found in Hitchcock's films, but the filmmaker kept after the studio's front office until the executives relented. He was told, however, that he would have to shoot the film on an extremely limited budget—no more than $800,000. Surprisingly, Hitchcock accepted the budget restrictions and went a... ...ces, nor was it a great performance or their enjoyment of the novel. They were aroused by pure film. That's why I take pride in the fact that PSYCHO, more than any of my other pictures, is a film that belongs to filmmakers." This was no news to Hitchcock's fans. In a 1947 press conference the great director laid out his philosophy of the mystery-horror genre: "I am to provide the public with beneficial shocks. Civilization has become so protective that we're no longer able to get our goose bumps instinctively. The only way to remove the numbness and revive our moral equilibrium is to use artificial means to bring about the shock. The best way to achieve that, it seems to me, is through a movie." PSYCHO provided shocks heard around the world and became an instant smash, breaking all box-office records in its initial release. Hitchcock had a horselaugh on the Paramount executives who wanted no part of PSYCHO from the beginning. The film became one of Paramount's largest grossing pictures and it made Hitchcock not only a master of the modern horror film but also fabulously wealthy. He had outwitted everyone—the industry, the audience, and the critics.

Free Antigone Essays: The Human Condition :: Antigone essays

Exposing the Human Condition in Antigone  Ã‚   Heroism entails several things; a selfless act, courage, or the accomplishments of bold and daring expeditions. A hero can also mean courage in the face of death. Others may view this type of hero as stupid, or a martyr. Every hero has faults and these faults along with heroic deeds make the man or woman; a hero, heroine. "Antigone" would be considered a hero in the sense of being a martyr. Because of her love for her family Antigone wanted to give her brother a proper burial, and even though he did evil deeds, she respected him. She believed that all of the dead were in a state of equality. When faced with the decision to obey the King or obey her heart, she says on page 23, in lines 86-90: â€Å"I will bury him myself./If I die for doing that, good:/I will stay with him, brother;/and my crime will be devotion.† This decision, to bury her brother, was very heroic in that even though she knew death was at stake, she knew where her loyalties lied. On page 39, lines 560-575, Antigone stands up to her uncle and tells him to his face that he has disobeyed the Gods decrees. In line 562, 563, and 564 she says: â€Å"I did not intend to pay, before the gods,/for breaking these laws/because of my fear of one man and his principles.† Antigone accuses Kreon of overstepping the laws of the gods, by relying on his own thinking. As is brought out later, Kreon never listened to other peoples advice until it was too late. In the above passage Antigone heroically faces up to the most powerful man, the King, knowing he could kill her in an instance, but still she tells him he is wrong. Being strongly tied to a family, where you would risk death is one thing, but as in any family a person usually takes their anger and frustrations out on individual family members, as in this passage on page 24, lines 100-103: â€Å"Then weakness will be your plea./I am different. I love my brother/and I’m going to bury him, now.† Antigone, non-heroically, accuses Ismene of not loving her brother, but of course Ismene loved her brother, Ismene was just afraid of the king. Antigone, in the heat of the moment, took Ismene’s frightened state as a sign of the lack of love on Ismene’s part.

Freefall and Projectile Motion

Freefall and Projectile Motion Introduction and Objectives This lab experiment was done to determine the characteristics of free fall and projectile motion in Physics. The motion in which a body is thrown or projected is called Projectile motion while free fall is any motion of a body where gravity is the only force acting upon it, at least initially. In this experiment, a photogate, a chopper, and a Universal Lab Interface were used to determine the free fall motion of the chopper as it was released. A ball, carbon paper, and an L-shape projector were also used to determine the range of projectile motion of a ball being released from a horizontal yet slightly vertical slope. At the end of the experiment, one will know how velocity and time affect the acceleration of a free falling object and its projectile motion. Thoery Aristotle stated in his theory of motion that the fall of a heavy object toward the center of the earth is a natural motion because the object is just returning to its natural place. He also stated that heavy objects fall faster than lighter ones because increase in the rate of motion is proportional to the weight of the object. Galileo’s theory states that the when a ball was rolled down an inclined plane at fixed angle? ; the ratio of the distance covered to the square of the corresponding time was always the same, but that when the angle of inclination is changed, the constant also changes but remains the same for the same angle. The constant d/t2 is also the constant for falling object (refers to the acceleration due to gravity). The experimental range used in the experiment is 45 cm, and the expression of the range of the projectile was found in terms of Vg and h. The horizontal distance traveled by the projectile for the total time of flight is given simply by R=vxt where t is the total time of flight and vx is the constant horizontal velocity. The time of flight was found using the equation for vertical motion, which is y=yi + viyt-1/2gt^2. After each experiment, the Logger Pro software determined the curve of the time vs velocity graph to determine which had a better Linear fit, either the Quadratic or the Linear curve. http://physicse-book8. blogspot. com/) Results and Discussion A.

It was shown that under the influence of gravity, an object falls on its own with its velocity accelerating at a constant pace. It is said that when the only force acting on an object is the Earth’s gravitational force,it is in free fall. There cannot be any other force acting upon it, especially air resistance, which should either be absent or ignored by its minute size. The force of gravity on an object is nearly constant when the object in free fall is near the earth’s surface. Because of this, the object accelerates downward at a constant rate. This acceleration is usually represented with the symbol g. In this experiment, a precise timer was connected to the computer and a Photogate was used to measure the acceleration due to gravity. â€Å"The Photogate has a beam of infrared light that travels from one side to the other. It can detect whenever this beam is blocked. † A Picket Fence or a chopper, a piece of clear plastic with equally spread out black sections on it, was dropped. As the Picket Fence passes through the Photogate, the computer will measure the time from the leading edge of one bar blocking the beam until the leading edge of the next bar blocks the beam. † This timing continues as all eight bars pass through the Photogate. From these measured times, the program will calculate the velocities and accelerations for this motion and graphs will be plotted. http://www. waukeshasouth. com/physics1/photo. html http://www. oppapers. com/essays/Picket-Fence-Free-Fall/567967
