Marfan Syndrome Essay Example

Marfan Syndrome Essay Example Marfan Syndrome Essay Marfan Syndrome Essay Marfan Syndrome Have you ever wondered about the diseases that you can get from your parents? One of these major diseases that can change someone’s life is called the Marfan Syndrome. Marfan Syndrome is a disorder of connective tissue that is inherited from the parents. The bones and circulatory system are usually the parts of the body that are longer and the ones that are changed because of the disease. There are many things that can cause a disease. Marfan syndrome is caused by a mutation in the fibrillin-1 gene. The gene produces a protein that is essential for formatting the elastic fibers found in connective tissue. About 75 percent of people with Marfan syndrome inherit the mutation from one affected parent. A parent who has Marfan syndrome has a 50 percent chance of passing the disease on to his or her child. Two unaffected parents have a 1 in 10,000 chance of having a child with Marfan syndrome. About 25 percent of Marfan syndrome cases result from a new mutation in the gene. Marfan syndrome affects different people in different ways. Some people have only mild symptoms such as their body and bones being longer. On the other hand, other people are more severely affected because it affects their vital organ(s) or organ system(s). The body systems most often affected by Marfan syndrome are the Skeleton, Eyes, Heart and blood vessels, Nervous system, Skin, and the Lungs. However, in most cases, the more someone ages, the more the Marfan syndrome symptoms will progress. So because of this the person will not relieve that they have the disease. The life of someone with Marfan Syndrome is very different than someone with no disease. One of the most important things is to avoid putting extra stress on the heart. That means avoiding any sport where theres a lot of running, physical contact, muscle straining, or the chance of getting hit in the chest. Some examples would be things like basketball, football, baseball, gymnastics, weightlifting, and track. The people with Marfan syndrome can only play safe activates (activates that are given by the doctor). The Safe activities are usually competitive bike riding, swimming, or dancing. Another thing people who have Marfan syndrome should never do is smoke or use tobacco products. Other than the examples of things that they cannot do, people with Marfan syndrome are just like everyone else, only maybe a little taller. Some diseases can be passed from one person to another but Marfan Syndrome isn’t one of those diseases. In most cases, the gene for Marfan syndrome runs in families, getting passed down to children from parents who have the disease. In these cases, a kid may have grandparents, aunts, uncles, or cousins who also have the disease. Every kid born to a parent who has Marfan syndrome has a 50% chance of having it, too. Sometimes, though, neither parent has the disease. In these cases, a normal gene accidentally changed when a baby was first developing. This baby will be the first person in his or her family to have the disease, and as a grown-up will have a 50% chance of passing the changed gene on to each of his or her children. If someone had a disease it would make their lives different than someone with no disease. Teens with Marfan syndrome who are nearsighted will probably have to wear glasses or contact lenses. If the lens of the eye becomes severely damaged, surgery may be necessary to fix eye problems. Some Teens develop scoliosis, abnormal curve in the spine, and then they have to wear a special back brace. Sometimes severe cases of scoliosis and chest wall problems may require surgery. If the person has heart problems associated with Marfan syndrome would need to have heart surgery or always take antibiotics to prevent an infection in the walls of the heart, which would be caused by the bacteria entering the bloodstream. You would need to take them before going outside, regularly waking up in the morning or even going to sleep at night. If you were to have Marfan Syndrome, it would affect your organ systems and make you look/be different than other people that don’t have a disease. Examples of organ systems that are affected by Marfan Syndrome would be the Skeletal system, the muscular system, your heart and you blood vessels. It would affect your bone by making you very tall, slender, and loose jointed. You’re Arms, legs, fingers, and toes may be disproportionately long in relation to the rest of the body because Marfan syndrome affects the long bones of the skeleton. A person with Marfan syndrome usually has a long, narrow face, and the roof of the mouth may be arched, causing the teeth to be crowded. It weakens and stretches your muscles and begins to place weight on the vertebrae in the lower spine. It would also start to wear away the bone surrounding the spinal cord. It would also make your heart weaker and more vulnerable to damage and kill the person with the disease. It would then affect your blood vessels by making the large artery that carries blood from the heart to the rest of the body, weak and it will stretch. Then because of this it will increase the risk that the artery will erupt and if it does it will cause serious heart problems or sudden death. Our Lives are very short and when you have a disease it makes your life even shorter. People with Marfan Syndrome have to face this catastrophe everyday of their lives. Wondering when they will die because of their disease. If I had a genetic disease, I would be very sad and not happy because I would wonder when I would die. The people who don’t have this disease should ask their selves, â€Å"What would I do if I had a genetic disease†? You should always ask you’re self because you never know what can happen to someone in one lifetime. â€Å"

IRAC Analysis on The Ranks Essay Example | Topics and Well Written Essays - 500 words

IRAC Analysis on The Ranks - Essay Example The overbreadth doctrine also allows people whose own speech or conduct is not prohibited to challenge limitations on free speech (such as those in picketing) on behalf of others who may refrain from doing so out of the fear of prosecution. The violation of the First Amendment right to freedom of speech is strong grounds for Jeff and Nicole Rank to protest against their arrest for wearing anti-Bush T-shirts. The written message on T-shirts constitutes written, symbolic communication which will be included in the protected category. Moreover, there has also been a violation of their fourteenth amendment right because the State has curtailed their privilege to attend the rally with the right to free expression of their opinion through the message on their T-shirts. There are only a few instances where the first amendment right to freedom of speech can be curtailed. The federal Government could argue that the incidential suppression of the First Amendment freedom of Jeff and Nicole is no greater than what is necessary to further the Government’s interest, i.e, in this case to prevent any disturbance erupting among the supporters of President Bush. However, they are unlikely to have any success with this argument, because Jeff and Nicole had worn the T-shirts for ten minutes at the rally without any indication of unrest among the crowd. This manual also provides strong grounds in Jeff and Nicole’s favor because it clearly states that â€Å"any physical contact with demonstrators† is to be avoided. According to the manual, action is to be taken to minimize demonstrator effect only when it is likely to cause some disruption, which was not so in this case. The Federal Government may try to argue that it was trying to prevent disruptive activity, but there was no sign of a potential disruption caused by Jeff and Nicole to the extent that it could be deemed necessary to restrain them, especially physically by

Discounted cash flow Essay Example | Topics and Well Written Essays - 750 words

Discounted cash flow - Essay Example One of the valuation tools that analysts use to determine the stock valuation is discounted cash flow. They try to determine current value estimating future cash flows. Cash Flow is taken into account while making all estimations. Cash Flow (Free) gives far clear picture about the company for it takes into account the change in working capital as well as all investments made during the period. It can be expressed as under. Cash Flow = Net Profit+ Depreciation/Amortization-Expenditures-changes in working cap. Analysts take into account cash flows because it is difficult to manipulate while earnings can be manipulated and adjusted. (Free Cash†¦) When estimated cash flows are discounted to the present value as per the cost of capital for the number of years of operation, it gives a clear picture for the benefits accrued from the investments made in the company. Mathematically, it can be expressed as Present Value = CF1/(1+K)+ CF2 / (1+K)2 +CF3/ (1+K)3 +.......[TCF / (K  - R)] / ( 1+K)n-1 CFi = Cash flow in the year 1, 2, 3†¦ K = discount rate TCF = Cash flow in the terminal year R= growth rate assumption beyond terminal year n = the number of years including the terminal year In short, above model gives the present value of the company based on the cash flow estimates of the future. DCF analysis implies that the company is worth all the cash that can be made available to the investors in the future. Future cash flows are discounted to the present value so that comparison becomes possible on investments made and benefits accrued. All future benefits of the investments made accrue at different time intervals, for example, at the end of year 1, 2, 3, and so on. Methodology and formula is same for all the analysts yet end results will differ for the following reasons. 1. The Discount Rate taken into calculation will be different for different analyst. The discount rate is usually the cost of capital. Each company is made of debt and equity in its capital st ructure. The cost of debt can be known easily as per the going rate in the market but estimating the cost of equity is a bit complicated task where each analyst applies his or her judgment. The equity is shareholder’s money and not without the cost. It has also certain indirect cost implications. The share holders of the company expect to obtain a certain return on their equity investments. Equity is a risk capital and depending upon the general economic conditions of the market, share holder wants certain minimum return over and above risk free return available to them in the market. If the company does not meet shareholder’s expectation, they will simple exit from the company. That will cause the fall in the market price of the shares. In other words, the company must give some minimum return to the shareholders to maintain the price of shares in the market. This is, in a way, the cost of equity for the company. Every analyst will have own perception on this cost of equity. Thus, each analyst will have some different discounting factor in their mind. This will also vary as per the economic conditions of the country and risk factors associated with the company. 2. Cash Flow Forecast is another critical parameter where two analysts estimate always differ. It is always easy to forecast the cash flow for a few years down the line but it is not possible to have these estimates without error beyond few years. Each analyst’s perception about future market conditions and overall economic scenarios come into play. Some analyst may have a cautious approach in estimation of future cash flows while other may be a bit liberal or optimist in the projections. It is obvious that this will have a bearing on the valuation of the stock and cause variance on valuation of the stock. (Free Cash†¦) 3. The Growth Rate beyond the terminal year is a long visionary assumption. Farther we go, more difficult it becomes to arrive at the agreement on values. When company reaches to the maturity cycle after a few years of operation, it

Dq-4-Sheila - Essay Example example, the case study provided in this research involves studying the effects of the 2010 murder in Northern Illinois University among parents, students as well as the Faculty members. Normally this is the second step in implementing any type of research design. The objectives are usually formulated to serve a purpose of a guiding formula for undertaking a research; they are usually formulated in a realistic and manageable to ensure that the research meets all the intended objectives for instance (Alter, 2013): The case study provided, could be guided by an objective of studying and identifying the psychological effects of the 2010 murder among students and other concerned stakeholders. There are different types of data. However, it is usually crucial for any researcher to identify and determine the appropriate data that his intended research will require. Additionally, the researcher should identify and state the sources of data, taking in consideration the nature of his/her study for example if the research is a case study, the researcher could opt for qualitative or quantitative data recorded in books as well as other primary sources of data that could be collected through interviews (Alter, 2013). This information is usually properly stated at the beginning of the research for readers to have an insight regarding the intended research dimensions presented. There are different techniques applied in collecting research data; however, the criteria for selecting any research technique is usually based on the type of data needed, taking into consideration the research design as well as the objectives for instance, a theoretical research would majorly depend on qualitative data, which can be collected through focus group interviews or even observation (Bryman & Cramer, 2011). This is the fifth step of implementing a research design; identification of a study scope is crucial for purposes of determining the sample size as well as the geographical coverage of a

Mosque Is A Worship Place For Muslims English Language Essay

Mosque Is A Worship Place For Muslims English Language Essay Mosque is a worship place for Muslims. Its function not just performs salat purposely but it can be as well as a center for information, education, and dispute settlement. As we know, mosque basically dealing with sounds which in delivering religious matters such as Friday sermon and lectures which most important speech activities in mosque. Through these activities, the congregation will be hearing messages of reminder of their religious and social duties. A study was carry out about acoustics and speech intelligibility quality of Kampung Laut Mosque, Kota Bharu (Ngasri Dimon, 2007), they determine the acoustic quality of the mosque such as reverberation time (RT60), speech level distribution in the main hall and speech intelligibility quality which involving different type of situation. In this study, they undergoes several acoustic quality analysis which are RT60 analysis, ray tracing analysis, sound pressure level (SPL) analysis and speech intelligibility prediction based on Speech Transmission Index (STI) and Rapid Speech Transmission Index (RASTI) lead to indicate that mosque posses good quality and good speech intelligibility when kuliah or khutbah is performed.[1] Acoustic is a very important nowadays, it does not restrict to the study of musical only. Acoustics is such a wide course which related to physical acoustics, psychoacoustics, electro acoustic, noise control, shock and vibration, underwater acoustics, physiological acoustic and etc. In Malaysia, there is standard that organized by Department of Occupational Safety and Health on the noise control. Noise is unwanted sound that harmful and will effects to our hearing sense. Consequences from that, it will lead to accident. The normal range of hearing for a healthy young person is from approximately 20 Hz (Hertz) to 20,000 Hz (20 kHz). 1.2 Problem Statement Acoustic quality in mosque is very important. Mosque is a building where worshipper perform for their pray. So, it must be conducive in term of sound which audibility. The worshipper cant get the message or unpleasant to do their religious activity sometimes and it need to be improve. Several studies have been made about the acoustic quality which most of them come from out of our country. In Malaysia, acoustic engineering does not wide like other engineering. So, to implement this kind of quality does not taking serious. Most of our mosque here, the buildings more focus on the decent architectural design. Besides that, in the main hall prayer also come with astonishing look which somehow adaptation from other great design in the world. This is good regarding to modernization of architectural design but acoustical quality also should be considered too. According to CAHRISMA project that researched by Zerhan Karabiber about ancient buildings, it states conservation and restoration of the architectural heritage were restricted with material means until now. However, it is obvious that, preserving an architectural heritage also should includes with acoustical heritage, especially the spaces that has acoustical importance.[2] Al-Wathiqu Billah Tuanku Mizan Zainal Abidin Mosque,  UiTM  Shah Alam is newly mosque upgrading from their old building which formerly known as Pusat Islam UiTM. This mosque fully finished their renovation on 2010 which come out with new architectural design in their main hall prayer. Tuanku Mizan Mosque is not same like other mosque, it just only has one beautiful minaret and upper space of the building is flat which does not have dome. Upon to its uniqueness, a study should be made to evaluate whether this mosque has good acoustical quality. In addition, throughout this study also, we can improvise and learns in spite of implement the acoustic learning course offered in Faculty of Mechanical Engineering, UiTM. The result of this study can be aid to design a new mosque in the future. 1.3 Objective The main objective is to study the acoustic quality in Al-Wathiqu Billah Tuanku Mizan Zainal Abidin Mosque,  UiTM  Shah in order to gain understanding about the good criteria needed in designing acoustic in mosque To determine the reverberation time, RT60 during semi-fully and fully occupied. To study the signal-to-noise ratio in the mosque during semi-fully and fully occupied. 1.4 Scope of Project The scope of the project is to investigate the good criteria needed in designing acoustic in mosque. There are several criteria need to carry out in this project such as study of reverberation time (RT60), Speech intelligibility, Noise Control and etc. As a result, sound contour mapping will be determined for RT60 at certain places in main hall prayer in the mosque. Besides that, throughout the studies also we could understand circumstances that effect to acoustic in the mosque and the way to counter it. 1.5 Significant Project This study was carrying out to gain the understanding about acoustic quality in the mosque. Thus, it will promote the value of acoustic in a building which does not focusing on the mosque only. In addition, it will help to improve the deficiency of acoustic quality and performing some guidance on designing mosque in future. Chapter 2 Literature review 2.1 Mosque 2.1.1 Definition Mosque is defined as the place of worship for Muslim. One of the most repeated building types in Muslim countries. In Malaysia, lot of mosque resembles mosque found in Java. The mosque serves as a place where  Muslims  can come together for  salat  (prayer) as well as a center for information, education, and etc. File:Quba.jpg Figure 2.1 : First mosque in the world, Quba Mosque First mosque (Figure 2.1) in the world built in Quba, Medina in Saudi Arabia. It was built during prophet Muhammad S.A.W on his way for emigration from Mecca to Medina, Saudi Arabia. The present mosque of Quba is a rebuild building. When Abdel-Wahed El-Wakil, Egyptian architect  was commissioned on 1980s, he conceived larger mosque and preserve the older design but the client eventually decided to pull down the old mosque and completely replace with new building. This mosque is a significant building to Muslim people nowadays due to its history.[3] 2.1.2 Architectural / Room Acoustic Room acoustic or architectural acoustic is the science of noise control within the building. This acoustical design quite important in making a hall that has acoustical purpose such as lecture hall, auditorium and etc. This study is to provide for maximum intelligibility of the speech while also in maintaining a natural voice. The first implementation of the architectural acoustic is in the opera houses then concert halls. Every single building has its own acoustic requirement depending to the purpose of the building. Sà ¼leymaniye Mosque(Figure 2.2), was built by Architect Sinan in 1557 is a great architectural acoustic building. The uniqueness of this building has the mosques main dome was found to have 256 symmetrically placed cubes measuring 15 centimeters around the front and 45 centimeters in length, which contribute to very good acoustic quality in this mosque. Some coresspondance said no need microphone there and the speech intelligibility very good. Unfortunately, after a few restorations relating to its heritage, the mosque already lost their uniqueness. Local people claimed that they cannot hear the sermon clearly as usual after that. http://img1.eramuslim.com/fckfiles/image/dunia/suleymaniye-mosque.jpg Figure 2.2 : Sà ¼leymaniye Mosque in Istanbul, Turkey 2.1.3 History of Al-Wathiqu Billah Tuanku Mizan Zainal Abidin Mosque,   UiTM  Shah Alam Al-Wathiqu Billah Tuanku Mizan Zainal Abidin Mosque,  UiTM  Shah Alam is located at top of hill nearby with Kolej Seroja and Faculty of Applied Science, about 1.5 km from Faculty of Mechanical Engineering. This Mosque has their own history which is known as Islamic Education Centre (IEP) at beginning of their established on  1st April 1983. In order with modernization, this centre was revised its name by Y.Bhg.  Dato  Seri  Prof Dr.  Ibrahim Abu Shah, Vice Chancellor UiTM on 1st January 2004 become Centre  for Islamic Thought and Understanding (CITU). CITU was supervised by a director and assist with two vice director that responsible to Islamic academic and non-academic in the UiTM Shah Alam campus. The establishment of CITU in UiTM is a combination of Islamic Education Centre (IEP) with the Religious Advisory Centre (non-academic) in which all Islamic activities governed by the University under one roof with the Islamic Centre at the university. After a few years, CITU has undergone renovation which incriminates a few parts that need to be maintaining in its building such as a new minaret and its main hall prayer. In 2010, UiTM move one step ahead in elevate Islam as main religion in our country and desire emerge as World Class University by introducing Al-Wathiqu Billah Tuanku Mizan Zainal Abidin Mosque,  UiTM  Shah Alam.[4] 2.1.4 Mosque Features The area and volume of this mosque is calculated based on Architectural drawing that been provided by Unit Rekabentuk Projek, Bahagian Fasiliti UiTM, a department that responsible to plan or proposing the features of this mosque. C:UsersfirdausyusufPicturesBukit Raja-20121130-00173.jpg Figure 2.3: Site plan on architecture drawing of UiTM mosque The mosque has an estimated volume is 62,720 m and it can accommodate 7000 person at a time. The floor area of the mosque about 3136 m and for the main prayer hall floor area estimated of 1600 m. It is 56 x 56m, with height of 20m. Each area calculations of main prayer hall is as shown in Table 1. TABLE 2.1 Summarise area of Al-Wathiqu Billah Tuanku Mizan Zainal Abidin Mosque,  UiTM  Shah Alam Surface Type Surface Area (S), m Carpet Floor 1,600 Plaster Ceiling 2,240 Plaster Front wall 1,120 Plaster Side wall 800 Plaster Back wall 960 Glass Side door 36 Glass Back door 36 2.2 Sound 2.2.1 Sound Mechanical Wave Sound is defined as pressure variation in term of mechanical wave that travels through a medium from one location to another. This phenomenon occurs when the wave is set off; it sets the nearest layer of particles of air into motion and corresponding energy to it in example vibration disturbance. This transport of mechanical energy through a medium by particle interaction is what makes a sound wave a mechanical wave. A vibrational disturbance is interpreted as (audible) sound if its frequency lies in the interval from 20 Hz to 20 000 Hz. Depending on the properties of the medium, sound propagates at different speeds. Medium Speed of sound (m/s) Air 340 Water 1500 Steel 5000 Sound wave behaviour is same with light and other wave behaviours. The sound wave may exhibits reflection, interference (two waves superimpose to execute resultant wave), refraction and diffraction.[5] 2.3 Early Decay Time (EDT) In describing the decay of a reverberant tail of sound energy in room, Sabines equation states the relationship between low absorption to its internal volume. Sabine in his study was discovered that sound like many other quantities which have a half-life. These produce an exponential curve that against increasing time graph (Figure 1). This pattern of graph much like the decay of radioactive material or carbon-14 that been use by archaeologist in the dating process. In other example to describe the decay time is the decay of light in a light -emitting diode (LED) and the voltage across a capacitor. The behaviour of this kind of energy, Sabine through its equation estimates the time required for energy to reflect until becomes inaudible (-60 dB) after the sound source been interrupted the RT60. http://www.synaudcon.com/site/wp-content/uploads/2010/02/EDT_as_a_Performance_Benchmark-fig1-e1266328072561.png Figure 2.4 : reverberant energy decays exponentially EDT is roughly defined as the sensation of RT. It is better indicator of subjective feeling of reverberation time, and is critical defining the acoustical quality of a music hall. By comparing the initial rate of reverberant sound decay and reverberation time likely appears initial rate more important than the total reverberation time. Decay time likely important too since it more rapid initial decay is interpreted by the human ear as meaning that the reverberation time is short. EDT should not be higher than  ± 10% for good acoustics. For liturgical purposes, EDT should be between 2.7 and 3.85 (Templeton, 1993). Things to avoid in design include the following: Echoes. An echo is a strong reflected sound that is arriving at the listener after the direct sound sufficiently delayed that it can be heard as a separate entity rather than as a continuation of the original sound. When echoes are heard, the most likely culprit is the rear wall of the room. Flutter echoes. Flutter echoes are a series of echoes that occur in rapid succession; they usually result from reflections between two parallel surfaces that are highly reflective. Sound focusing. Focusing of sound can be caused by reflection from large concave surfaces. Certain sounds will be heard too loudly near the focus of a curved surface. Sound shadows. Under balconies at the rear of an auditorium or church there may be insufficient early sound, since most of the reflections from the side walls and ceiling do not reach this area even though they are in a direct line of sight to the performer and therefore receive the direct sound. [6] 2.4 Speech Intelligibility Speech intelligibility is the measure of the effectiveness of speech which its expressed of percentage of a message that correctly delivered and understood. In term of understanding, speech intelligibility does not same with speech quality because speech quality refers to message that want to delivers that may be understood by the listener. A message that lacks quality may still be intelligible. C:UsersfirdausyusufDesktopFYPmeasurement speech.jpg Table 2.2 : Speech Inteligibilty Test Method Table above shows speech intelligibility test method which standardizes by International Electrotechnical Commission (IEC) and International Standards Organization (ISO) standards that already incorporate objective methods for evaluating speech intelligibility. 2.5 Reverberation Time that required for a sound in a room to dies out which specifically decays by 60 dB in a room after the sound from its source has stopped is known as reverberation time (RT). RT is the basic parameter that should be calculated in the study of acoustic. Reverberation time specifying the efficiency of sound decays in a room for fulfilling the acoustical requirement depending upon the activities conducted in certain time. JBL Professional Sound System Design Manual reverberation time was simply described about the length of time required for a very loud sound to die away to inaudibility. It was later defined in more specific terms as the actual time required for sound to decay 60 decibels.[5] RT60 was found by Wallace Clement Sabine, a professor at Harvard University in the early 1900s who was the first person that quantifies this quality subject. W.C. Sabine has come out equation below due to his study on acoustic of the Fogg lecture hall: RT = Where, V = volume in cubic meters, S = total surface area of the room in square meters, = average absorption coefficient in the room According to past study in the mosque, RTis 7.48 s in the middle frequencies. This much longer than the optimum level even for liturgical purposes. Liturgical purpose refers to orchestra, chorus or organ which the optimum range level for reverberation time is about 3.0 to 3.5 s for spaces larger than 1000 m(Egan, 1994). Long sound decay at low frequencies can reduce the intelligibility of speech. For good intelligibility, RT values at low octave band should remain flat down to 100 Hz. At low frequency, an increase in RT values of around 10%-20% would still yield a natural sound. 2.6 Signal-to-Noise Ratio Noise is a sound which known as unwanted signal or damaging sound that may damage your hearing. It also can cause to other health effects such as stress, increased heart rate level, increased blood pressure and hypersensitivity to no noise. It can also interfere with communication at work, which could lead to accidents. For healthy young person, the normal range hearing is from approximately 20 Hz (Hertz) to 20,000 Hz (20 kHz). Our ears are more sensitive to the middle frequencies, which range from 500 Hz to 4000 Hz the speech frequencies. Signal-to-noise ratio defined as a measure of desired signal level to unwanted signal (noise). It is also known as the ratio of signal power to the noise power in a space. This describes the level of noise that exerts from output device such as fan and refrigerant, in relation to signal level. http://www.socialresearchmethods.net/kb/Assets/images/expclas1.gif Figure 2.5 : Two signal which referring to wanted signal which does not disturb and unwanted signal (alternate amplitude). Due to ratio between noise and signal, it often expressed in logarithmic decibel scale. Signal-to-noise ratio (dB) = 10 Where; = Pressure for signal (dB) = Pressure (signal + noise) in dB Chapter 3 Methodology Research methodology is one of the important parts in this study. A systematic methodology was created which to ensure that the research will be running smooth and successfully. In order to carry out the research, this methodology comes out with 5 stages which stated in the flowchart below. This flowchart is important to describing the way or designing the method that being use. Flowchart of the proposal methodology 3.1 Preliminary Preparation 3.1.1 Introduction to acoustic and understanding on the basic concept of the study. In this stage more on understanding of the basic concept about the study. This includes by doing some observation on past study and the sources that will provide the information that related to this study such as from library, book, internet, journals and etc. There are some keyword been highlighted regarding to the research includes acoustic, speech intelligibility, architectural acoustic, sound propagation, and reverberation time (RT60). This fundamental knowledge is quite important to understand about study that will carry out to perform a good research. The keyword had been discussed in the literature review. 3.1.2 Collecting information details about the study Collecting data is quite tough job need to handle. As mentioned in the objective, object that will carry out for the experiment is UiTM Shah Alam Mosque. For your information, this mosque was built past 20 years ago and basically there is no research done on this mosque. So the information about the mosque is quite limited. A lot of stages needed in determining the details about the mosque: Observing the features inside the object about the experiment will carry out, UiTM Shah Alam Mosque includes: Glass doors (11 Units) Pillars in wooden covered (6 Units) Speaker (6 Units) Collect some detail about the history in making the mosque from Arkib UiTM Shah Alam Dealing with Unit Fasiliti, UiTM Shah Alam regarding to get the dimension and drawing about the object. Contacting the architect that handle the latest renovation to get some point and view about the material that been used in the object that will carry out for the experiment. 3.2 Experimental Study 3.2.1 Reverberation time (RT60) For experimental study stage, sound level meter plays its role in obtaining the sound pressure level in decibel (dB). Referring back to the objective, the study is to determining the reverberation time (RT60) which the time required for sound level from present level down to 60dB. The sound level meter will be placed in certain position in main hall prayer area. From this we can see the variation of the sound propagation inside the hall. This variation of the sound propagation will be translated into sound contour mapping by using Matlab software which inserting the time required from the experiment. 3.2.2 Signal-to-noise ratio This parameter will be determined by using sound spectrum analyzer. This spectrum analyzer is worked to differentiate the signal and noise in a space. The result from this observation, we can obtain the noise level in the condition as stated in the objective of the study. http://upload.wikimedia.org/wikipedia/commons/thumb/7/72/FSL.jpg/220px-FSL.jpg Figure 3.1 : Spectrum analyzer 3.3 Simulation using software Stage 3 which need to carry out the simulation by using software in computer lab provided in Faculty of Mechanical Engineering, UiTM Shah Alam. Regarding to Dr. Valliyappan David Natarajan, it is a new software that bought by the faculty conjunction to expanding demand in acoustics field. The software abilities can generate the architectural design instead of stimulates the sound propagation and speech intelligibility in the hall. 3.4 Data Analysis After computing both result by using experiment and simulation, it continue with the organizing all the result for the simulation and experiment. This analysis referred to do comparison for both conditions which is reverberation time and signal-to-noise ratio related to semi fully occupied and fully occupied people (peak hour) inside the hall. This analysis will come out in the plotted graph. In addition, the result of the analysis will be discussed. In spite of that, the result of experimental pattern will be compared with simulation that executed by the software. The comparison will be discussed in the short essay. 3.5 Report writing After going through in preparing the proposal, experiment and simulation, finally translate the entire chapter into report writing. The report writing consists of 6 chapters which the report must be below 100 pages.

Reality and Illusion in Shakespeares Hamlet - Appearance vs. Truth :: Shakespeare Hamlet Essays

Hamlet: Appearance vs. Reality One of the most famous and popular authors and script writers is William Shakespeare. Shakespeare has always been able to create interesting characters and one of the reasons they are so interesting might be that they are complex people with their inner selves differing from their outer selves. Are the characters in Hamlet the same on the inside as they appear to be on the outside? The characters in William Shakespeare's Hamlet can be studied in a manner relating to appearance versus reality. Some of these characters are Claudius, Rosencrantz and Guildenstern, and Hamlet. One character who enables us to examine the theme of appearance versus reality is Claudius, the new King of Denmark. In Act One, Scene Two Claudius acts as though he really cares for his brother and grieves over the elder Hamlet's death. This is shown in his first speech addressed to his court, "and that it us befitted/To bear our hearts in grief, and our whole kingdom/To be contracted in one brow of woe" (Shakespeare I22-4). It is shown further on in the same speech when he says, "our late dear brother's death" (Shakespeare I219). However, this is not how Claudius truly feels about his brothers death, for Claudius is the one who murders elder Hamlet. We see the proof of this in Claudius' soliloquy when he appears to be praying; "O, my offence is rank, it smells to heaven./It hath the primal eldest curse upon't/A brother's murder" (Shakespeare III336-38). Another love which Claudius fakes is the love he has towards his nephew and stepson, Hamlet. In his first speech to his court Claudius tells Hamlet not to leave for school but to remain in Denmark; "It is most retrograde to our desire/And we do beseech you, bend you to remain/Here in the cheer and comfort of our eye" (Shakespeare I2114-117). However, later in the play Claudius develops a plan to send Hamlet away from Denmark with the aid of Rosencrantz and Guildenstern; "And he [Hamlet] to England shall along with you [R & G]" (Shakespeare III34). Claudius also refers to himself as "Thy loving father, Hamlet" (Shakespeare IV350) but when Hamlet is out of the room a few moments later Claudius has a complete change of face in which he reveals his plan to have Hamlet executed; "Our sovereign process, which imports at full/By letters congruing to that effect/The present death of Hamlet" (Shakespeare IV363-65). Even the love Claudius showed for Gertrude can be questioned in its validity. Claudius, near the beginning of the play, appears to be happy about
