Oedipus Rex, Hamlet, Willy Loman Comparison Essay

â€Å"Still, the Truth Remains† An immense desire for personal satisfaction, and extraordinary reputation can often result in a sickly, perverse distortion of reality. In Sophocles’ Oedipus Rex, a man well known for his intellect and wisdom, finds himself blind to the truth of his life, and his parentage. William Shakespeare’s Hamlet also contains a character that is in search of the truth, which ultimately leads to his own demise, as well as the demise of many around him. Arthur Miller’s play, The Death of a Salesman, tells of a tragic character so wrapped up in his delusional world, that reality and illusion fuse, causing an internal explosion that leads to his downfall. Each play enacts the struggle of a man attempting to come to grips†¦show more content†¦Oedipus’ foolish decisions ultimately lead to his downfall in the play. Oedipus chooses to kill Laios. He chooses to marry Iocaste. He chooses to forcefully, and publicly, assume the mission of discovering the identity of L aios’ murderer saying ironically, â€Å"I say I take the son’s part, just as though I were his son, to press the fight for him and see it won,† (633). He proceeds on this mission and chooses to ignore the warnings of Creon, Iocaste, Teiresias, the messenger, the shepherd, and anyone who attempts to stand between him and the truth; and, he chooses to blind himself. In the end, Oedipus’ most foolish choice prevails throughout the play; the choice of illusion over reality ultimately costs him his life. Similar to the quest for truth in Oedipus’ case, so does Hamlet lead to his own decease. In the first act of William Shakespeare’s Hamlet, after Hamlet is aware of the tormented ghost of his father walking on the ramparts, he goes to witness it for himself. This immediately exemplifies the theory that Hamlet, like Oedipus, is in search of the truth, until he realizes it is too much to bear. Subsequent to seeing the apparition, he is convinced to avenge his father’s murderer. The ghost tells him, â€Å"Revenge his foul and most unnatural murder,† (29). As Hamlet lays the trap for the new King Claudius, he is procrastinating in order to solve his self-doubt. Even after the ghost tells Hamlet how his father was murdered, Hamlet has the players act

BE CERTAIN THAT YOU HAVE SOME EVIDENCE (paraphrase or quote) AND PAGE NUMBER Gang of Robbers (Chapter 3) In the novel, Mark Twain uses satire to mock different aspects of his world. Before Huck and Jim even make it to the Mississippi, In St. Petersburg, Huck encounters many different aspects and situations made to make fun of, and laugh at American society. Through Jim, Twain mocks slavery, and the way that people treated African Americans. Miss Watson is an example, where she is revered as a good, strong Christian woman, with many strong moral convictions, but owns slaves, and thinks nothing of selling them away from family. (Twain 13) Twain uses satire here to show how hypocritical it was, that someone referred to as a â€Å"Good Christian woman† can buy and trade people as if they were property. Another one of his targets of satire in this episode is the idea of romanticism. Twain uses Tom Sawyer as a window to the romantic view on life that was running rampant in the South at the time.

Patient-Centered Care Free Essays

Evidence Based Practice: Patient-centered Care1 Evidence Based Practice: Patient-centered Care Evidence Based Practice: Patient-centered Care2 Patient-centered Care In the definition of patient-centered care it states that we should recognize the patient as the source of control in providing compassionate and coordinated care based on respect for patient’s preferences, values, and needs(NAP, 2003). In this quantitative teaching strategy by Pamela Ironside, PhD, RN, FAAN she aims to do that, along with physical comfort and some emotional support for the family. In a culture as diverse as the United States it is of great importance that individuals in the health care field learn to communicate and understand each patient. We will write a custom essay sample on Patient-Centered Care or any similar topic only for you Order Now We must remember when implementing a communication strategy, that there are many elements that affect the experience: cultural variations, personal dignity, and interpersonal relationships. Gathering knowledge of patient’s beliefs, and values, along with community preferences can be an effective strategy to overcoming diversity and improving communication. It is important to understand not only that people are different but also how to embrace these differences in order to supply individuals with appropriate healthcare. This is a teaching strategy about a couple who thought they were doing the best for their first born child but in return was possibly going to lose them forever. There were decisions that they were going to have to make, whether to continue with the treatment or stop it. This was not a usual couple though, they were Buddhists and the staff had no idea what the rituals for death and dying were, along with looking different the couple had dread locks, tattoos, and Evidence Based Practice: Patient-centered Care3 multiple piercings but they also were a mother and father who may be losing their baby. As the nurse introduces herself, which is every time we enter the patient’s room, she is determined to find some sort of connection with the mother. Who turned out to be a very distraught mother who was unable to make any important decisions. The nurse realizes the mother is unable to make clear decisions and talks to her supervisor to set up a care conference so they could talk about this baby’s quality of life. There comes the time when you have to say â€Å"goodbye† to a loved one. Could you do it? Or would you want the doctor to do anything and everything possible to save your loved ones life? Each person has his or her own set of values, norms, and beliefs. Individuals share these with others from their own culture; however with the vast number of separate cultures today it is important to understand not only that people are different but also how to embrace these differences in order to supply individuals with appropriate healthcare. There are many ways in which differences and cultures can affect health care services. Different cultures have different beliefs about health, wellness, and healing. This couple wanted to keep their newborn away from all the â€Å"bugs† in the hospital, but that is possibly where his/her life ended. Showing support and respect for different health beliefs creates a better interpersonal relationship between patient and nurse along with the physician. Health care providers should seek and obtain knowledge of their patient’s diverse cultures. In today’s world of diversity, knowledge is a valuable resource.

Analysis of Sustainable Development of Oil and Gas Industries

Question: Describe and Critically analysis of sustainable development of oil and gas industries? Answer: Introduction In last 30 years, consumption of oil and gas has been increase on such amount that this world is highly relying on these fuels, i.e. the world is highly dependent on petroleum (Kloff and Wicks, 2009). According to the International Energy Information Administration (2014), the global oil intake increased to 62,900 thousand barrels per day in ninth decade to 89,800 in second decades of this millennium. Similar to oil intake, gas is on focused as clean and substitute of energy; and, the cost of gas is rising on yearly basis. The rapid consumption of oil and gas affected the increasing construction and distorted these resources from every aspect i.e. offshore and onshore, land and seabed, even dessert in untouched. We should admire the latest technology mainly in offshore area development. This is not limited to Gulf or American countries but reached to African countries and Brazil where petroleum discovered at later stage. In order to get more energy they are extending their work much deeper and wider into the sea as well as on ground also. A FPSO rig now 4000 meter of depth for sucking oil and serving the needed countries. (AGI, 2014) As an environmentalist, I am trying to investigate impact of oil and gas exploration, production and distribution on water pollution. Effect on Water due to Oil and Gas exploration A study done in 2009 by WHO and a team under E. dorathy, regarding the environmental condition of different location in around West Africa showing that the pH level of water has significantly risen from 7.33 to 8.47 pH units which out of the range of WHO recommendation, turbidity value ranges 1.46 to 2.83 just touching the upper line, the presence of iron found from 0.44 to 1.18 mg/L. The concentration of high iron is due to chemical reaction of huge and metamorphosed rocks which mixed with iron that ultimately. Cadmium ion range is analysed and found out of range of WHO acceptable values. This cadmium is dangerous for any living organism in the sea including mankind who consuming it. Lead is also present these are ranged between 0.08 to 0.483 mg/L. This can cause damage of brain, kidney and RBC. In recent new came to know that well and bigger reservoir also contaminated due to oil exploration, nut industry still denying such kind of problem, this matter is still under investigation through API. Some US states recived thousands of complain about short term slowing of water flow and pollution from stray gas or other substances. As we know that fracking (The drilling process to pump-out oil and gas) has increased in recent years and this requires very huge quantity of water, chemicals and sand into the ground to break apart the rock and pump-out the oil and gas. some part of this water along with thousand gallons of normal water came out to the surface, and it contain high level of chemicals, salt and heavy metals low level radiation. Effect on Water due to Oil and Gas refineries As we know that discharge from oils and refineries are creating lot of contamination to water. Leaking the effluents contaminates water on surface as well as underground water, this is mainly due to leakage in tanks and pipeline. A recent problem also in news that lot of water pollution happening due to storm and flood coming around the refineries. The last but not least oil and grease present in the sample is around 6.0 to 44mg/L, This increased oil and grease activity slowly polluting sea water. Which have serious implication for marine organism? All the above data shows that sea water in West Africa are highly affected. This affects the socio economical and seawater resources. To specify the existing regulation we have to discuss the role of different organisation in safety and environment protection for oil and gas. The main organisation involved in API, EUROPARL, APPEA etc. came into action. Since oil and gas leakage caused by offshore rigs Base on water used data in API 2012, in 2014 alone used about 3600 million m3 of water in USA only. The water coming with crude oil is known as produce water. According to survey in 2014, we are getting about 42 billion m3 of produced water from all around the world, and in this 55.2% of produced water is reinjected into the ground. Similarly for rigs, about 91% of water is simply discharged into the sea. Water pollution due to Oil and Gas distribution. The oil and gas still polluting the water when distribution happens. Frequent leaks are reported in different countries, but leakage for whole world is still unknown. According to environmental protection agency there are about 500000 confirm leakage notes down from different underground storage tank in 2012, these underground storage tanks are generally kept for storing the oil and gas product. This leakage from underground storage tanks leakage mixed with water resources beneath the ground. The total volume of leakage is still not known. Impact on drinkable water Oil and gas generation and combustion gives a significant impact on climate change such as greenhouse gas emission. But more important is that it also poisoning the drinkable water with wide variety of contaminants that is dangerous to human health. Women are particularly at risk for adverse effect of health which is due to this contaminated water. we have three choice, one is take alternate source of water, second is purify the contaminated water and third one is drink this water, all are costly affair either monetary of health. This also affects neighbour countries up to the land and this could effect in next countries also, international regulatory bodies are necessary to implement the safety of petroleum industries activities. In such condition IMO not able to implement such powerful tool that are more, stringent than those standard issued by other statutory bodies. As of now SOLAS and MARPOL are the stricter tool related to oil and gas and of the safety of Oil and gas and their environment protection. But they are applicable to petroleum and marine branch platforms generally; there have exemption of abiding these tool to logistics, however there is more likely of water pollution and contributed environment dissolution. Use of Biomass Biomass is latest renewable energy resources which include all plant and animals; in plant biomass energy is produced through photosynthesis which is a chemical reaction in the presence of sunlight. thi can be done in several energy crops. Energy cros are plant which is grown only for use as fuel or converting into biofuels such as ethano, biodiesel and biogas. In this process so many variety of bio-waste can be used such as agricultural waste, municipal solid waste, organic waste and industrial waste. The resources use is biomass is also having much amount of energy as in oil and gas. i.e. the energy content of wood is as much as 15 mega joules /kg of wood This can be sued as basic function from industrial waste of food waste items. Almost all biomass is in solid state and it can be burned in the same way as oil and gas, and it can be sued for heating the building, cooking, even it can produce electricity by running the turbine. It can be used in furnace by mixing with coal or other oil and gas product. In villages of India they are using this material as a biomass from beginning of human society. We can use biomass as a liquid fuel, in this liquid fuels we basically produce ethanol and biodiesel. The main process used in production of ethanol is fermentation process, this isnothing but bacterial biological in which glucose is converted into alcohol by action of bacteria and yiest. similarly we can produce biodiesel, but this normally produced from vegetable oils, greases and animal fats. In the process of making a biodiesel generally we are using catalyst and alcohol. the main catalyst used for biodiesel is potassium hydroxide. Most of the biodiesel are from soyabean oil. SOm of the techniques like production from algae are still in experimental stage.Biodiesel is mixed with petroleum diesel in the ratio about 20%. This can be directly sued as diesel in transport without changing the engine. However his technologies are still under development and need lot of research on it to fully replace the use of oil and gas for this bio product. we have stated later that huge amount of monetary resources are necessary for research and development, and I think this is the best area where we can research for replacing the oil and gas industries. This is the only way where we can lead to save environmental impact and increasing the quality work of regulatory bodies This is an necessary process for confirm and effective step towards improving ecosystem in one regulation. Suggested regulatory Ideas The is an issue of burning flare in all over globe, if we are aiming to prevent the damage of environment we have to use the regulations practically. The current oil and gas industries should be in such a way that, any restricted operation can be controlled by regulatory bodies on behalf of oil and gas industries by using latest equipment and technologies.The recommended suggestion is that API should have concern for petroleum business. This is the outcome of dissertation. This is because of better performance of API, stricter norms and powerful control in deep sea area, by cooperating with other bodies like IMO and ISA, the can gain control more easily than any other could in the future. This is the outline for recommended procedure for better tomorrow Collaboration between the APA and the IMO If these companies wants to remain competitive edge, they have to operation in always newer technological environment which if safer and doing less damage to environment. these are few which is already above stated, but inspite of above things these oil and gas industries can do the following things: By using the latest technology not only in oil and gas but also in other renewable energy source i.e. solar system and other hydroelectric project. By substituting the oil industries equipment to achieve minimized flaring of gases by adopting new processes. Besides the applying the stricter norms, the regulation bodies require some finance management in order the do research and development in oil and gas industrys all aspect. By venturing into the new market of developing countries or under developed countries, so that they will also get benefitted and create long term business opportunities for business to business approach.

Female In Genesis Essays - Book Of Genesis, Bereshit, Adam And Eve

Female In Genesis The Intimidating Female in Genesis In the narrative in the book of Genesis, there are two main objectives. The first is a general goal to create a complex world designed for ideal human existence according to divinely legislated principles. The second is God's desire to establish a great nation within this world. According to the narrative, God aims to achieve these goals by constructing frameworks for his goals and then enlisting carious humans to help see them to fruition. However, as amply demonstrated in Genesis, the human variable is volatile and frequently confronts God with instances of insubordination. As a Collective human element, women in Genesis often appear as obstacles to these broad-overriding goals through nonfulfillment of their particular roles in the divine scheme. From the Garden of Eden right through to the story of Joseph, women, as wives, mothers, and daughters, are typically unreliable, inadequate, deceitful or, simply by virtue of their womanhood, an outright liability, and they frequently threaten to undermine God's will as it is expressed in the opening book of the Bible. God's first instruction to a human being occurs during the initial telling of the creation story in Genesis. Adam and Eve have the mutual responsibility to be fruitful and multiply, fill the earth and subdue it(1:28). However, it is really the second narrative, detailing the creation of man and woman that establishes God's structure of the world. In this structure, Eden is created for the first man, Adam, who has one basic function, to work and guard Eden (2:15), and only one prohibition, to abstain from the fruit of the Tree of Knowledge (2:16). Starting right from Genesis, in this additional description of the Eden story, tension already arises between Eve, the first biblical woman (ironically, created specifically to complete the Eden habitat for Adam), and the divine process. Duped by the serpent, she not only succumbs and eats the forbidden fruit, but also encourages Adam to join her, thereby causing their expulsion. Thus, God is forces to confront human intractability from the very beginning of his quest, and the first instance comes from a woman, the very creature created to solidify Edenic perfection. God had intended Eden to be a self-contained universe, a paradise for Adam where he would live comfortably without toil or hardship. By disobeying, and then including Adam in her crime, Eve indirectly causes his punishment: a life that requires him to labor for his sustenance. Eve was created to be her husband's helpmate (2:20); instead she turns out to be a catalyst for his demise and the cause of humankind's expulsion from the Edenic Utopia. In the creation story, the satisfaction of both God and human are at stake. God aims to realize his will in the world, and the happiness and the content of humanity hinge on God's ability to realize his plan. Eve is created to complete Eden. But, instead of conforming to God's plan, she is a stumbling block to the construction of the divinely conceived universe. The idea that God is striving to create an ideal world recurs in Genesis. And in many instances, as in the case of Eve, it is a woman who impedes the fulfillment of God's vision. However, disobedient actions are not always the mode of obstruction. Sara and Rachel threaten God's plan with their infertility. Although the text does not explicitly blame the matriarchs for their inability to conceive, they are involuntarily liable for not propagating. In every instance, it is the matriarchs, rather than their husbands or God, who are passively the physical barriers to conception. God, the narrative explains, opens wombs when he so chooses. But closed wombs are never stated to be the result of God's initiative. And, even if conception is perceived as God's intervention, it is significant that infertility in the text is always a result of women's, rather than men's, faulty anatomical equipment, making infertility an inescapable female problem. Propagation is a central these in Genesis. In the Noah story, which is God's attempt to reconstruct the world after the first few generations of humankind have proven incorrigible, God commands Noah to be fruitful and multiply (9:1) immediately after Noah emerges from the ark. Clearly, the production of offspring is

defining a Patriot essays

defining a Patriot essays Ever since the towers came down, and the flags went up, there has been a widening split over the best way to fight this war on terror. New legislation created to deal with these threats was initially met with full support, as immediate action was needed to effectively respond to the attacks. In the past couple of years however, these laws have been more carefully scrutinized, and met with increasing opposition. The central issue to these concerns is the possible violations of civil liberties that these laws may allow. But the larger issue goes beyond the laws themselves, asking the question, Do the ends justify the means? In fighting this war on terror we have been forced to change the way we view and approach the world, and while most Americans agree that freedom is worth fighting for, we all have different ideas on how to protect it. One such piece of legislation, the Patriot Act, has become the poster child for people frustrated with the way the Bush administration has handled our security after 9-11. While there are questionable sections to the act that deserve our attention and analysis, the cries are more against the misrepresentation and disenfranchisement many are feeling. In fact, when it comes to protecting our country and promoting freedom throughout the world, we may be closer in policy than we think. The testimony of John Ashcroft to the committee on the Judiciary goes a long way in explaining why these rifts exist. Not only by what is said, but by the way he says it. Throughout this entire campaign the Bush administration has relied on fear to force people to accept its mandates. Mr. Ashcroft opens his remarks by reading off the names of 6 people killed on September 11th, and then goes into quoting the fanatical fatwas made against the United States by terrorists. This is used to put fear into our hearts, so that when he gets to the proposed amendments to the Patriot Act, we would find them...

Position paper Essay Example | Topics and Well Written Essays - 750 words - 3

Position paper - Essay Example During the ancient times buildings was a reflection of nature and the culture of the people. Aesthetic value of a house was considered important in architecture. However, modernity has changed everything. Tall buildings and malls are built in a plain. There is no uniqueness in the buildings that makes them appealing. Buildings no longer resonate with nature thus making it difficult for people to connect with the buildings. Formerly, a person could look at a building and immediately know the culture of the people or the resources available in the land in which it was constructed. The current housing designs are intended to meet the housing needs of the population. Aesthetic beauty of the buildings is not the main concern of the architects. Habitability of a house is what matters in the construction of a house. The buildings have, therefore, lost touch with the community in which they are built. The housing designs in America are just similar to the designs in Asia and other parts of the world. This means that buildings no longer have the cultural and natural appeal that existed before. Identity has been lost in the modern age architecture. Regional distinction of houses is no longer possible due to the similarity of houses. The break from the past in the modern age in the field of architecture is misplaced. The argument that advancement in technology and science should affect the design of buildings is wrong. The culture of the people may have changed but that does not justify a total migration from traditional designs to modern designs. A good number of people still value things that resonate with nature. People want things that they can easily connect with. This is why hotels and parks that have the natural look attract a high number of people. It is wrong to presume that modernity killed aesthetic significance that was attached to buildings. The

Explain the Law of Demand Research Paper Example | Topics and Well Written Essays - 500 words

Explain the Law of Demand - Research Paper Example The above demand curve shows that when the price of a product increases, the demand decreases whereas the demand increases when the price decreases. For example, Butler (2009) has mentioned that the Australian government recently decided to cut the tariffs on imported cars by 5-10% (Butler, 2009). The above decision will definitely reduce the car prices in Australia and subsequently the demand for car may increase in Australian market. Australians automobile industry is controlled mainly by Toyota, Ford, Holden and Mitsubishi. The new decision to cut down the taxes will help the above companies to sell more cars in Australian market by reducing the prices. The cut down of the tariffs and the prices of the vehicles will boost more economic activities across Australia as the above four companies will increase the supply of vehicles to Australia in order to exploit the favorable market condition. When supply increases, the price may come further down and more customers will participate in purchasing. Most of the people are familiar with the demand law. People will never go after expensive goods if substitute products of similar quality with less prices are available in the market. On the other hand, in the absence of substitute products, only the rich people will buy the expensive goods and others will stay away from the market. It is difficult for the companies to survive in a market relying only on the buying abilities of the rich people. A product can succeed in the market, if it is able to catch the demand not only from the rich people, but even from poor people since poor people constitute the majority of the population in most of the countries. It is not necessary that the demand for goods depend only on the price of the good. When a country acquires heavy economic growth, the goods previously less demanded may become more demanded in that country. For example, India is currently

Aircraft Crash Analysis & Design Essay Example | Topics and Well Written Essays - 500 words

Aircraft Crash Analysis & Design - Essay Example All of the 297 passengers and 12 crew members evacuated the aircraft before the fire reached the escape doors. All of the passengers and crew members survived with only 12 were seriously injured. People called it a miracle and the role played by the highly trained crew members in an emergency situation was appreciated. The passenger cabin had eight emergency exit doors. Six of the doors are used in Type A emergency and the other two doors are used in Type l emergency. All of the doors were similar in operation. They had a design to be opened either from interior or the exterior. According to the operating manual of Airbus cabin crew the instruction states that opening the doors from interior in normal operations, the door control handle must be completely up. All of the doors were equipped with door assist system which had an emergency operation cylinder and a damper. Damper helps in limiting the travel of the door in normal operations especially when the conditions are windy. But in an emergency situation the damper acts as an actuator in order to open the door automatically. The damper is operated by compressed nitrogen gas which is stored in specially designed cylinders which have pressure gauge. Slide arm lever controls the release of nitrogen by and actuating device. When the arm lever is at armed state as normally it is during landing as a result the door assist opens the door automatically. Each emergency door also has a prismatic lens. The plane had 8 evacuation escape devices to help in fast occupant way out in state of an emergency. It had 2 single lane slides at emergency doors R3 and L3 and six double lane rafts at emergency doors R1, R2, R4, L1 and L2. The deployment and inflation of the rafts were automatically started when the emergency doors are opened. Normally the deployment and inflation time of rafts is 16 seconds but on Airbus A340 it is 8 seconds. There is no sign that the international

Navel Model to Image Separation in Scanning Tinny Letter

Navel Model to Image Separation in Scanning Tinny Letter Somayeh Komeylian Department of Tel-Communication Engineering, Islamic Azad University South Tehran Branch, Tehran, Iran Armin Mehrabian Department of Medical, Mashhad Medical Science University, Mashhad, Iran Saeed Komeylian Factory of graduated students, Department of Tel-Communication Engineering, Sharif University of Technology, Tehran, Iran In this paper, a navel model has been introduced to image separation in scanning tinny letter. The proposed model is based on Almeida et al. (2006) model. First, the basic image separation method has been explained, and then the proposed pre-processing methods have been presented. In addition, separation method presents based on two sampled wavelet and contour transform which has adaptive structure. The result showed that proposed model has a good quality with a little runtime. On the other hand, this model which use directional filter bank has better effect in separation with approximately two level of decomposition. Finally, the two mainly proposed algorithms (NSWT and Improved NSCT) shows that, we achieve to really good results which our separated images have absolutely good quality by using preprocessing and these methods simultaneously. Keywords: Image separation; contour let; non-subsample wavelet. When we scan or photograph a paper document, especially if the paper is thin or transparent, the image from the backside often appears on the image from the front page. This is a routine problem which is usually occurs, when the electronic version of an old document or a book is needed. Extracting sources from mixture images is a problem of blind source separation. Independent Component Analysis (ICA) is one of the good solutions for this problem, which is done with linear and nonlinear ICA in [3] and [4], respectively. The results show that the nonlinear solution is better, because images are mixed through a nonlinear procedure. In [3] authors use a nonlinear method, which is named MISEP that is based on multilayer perception used in neural network. In the most of ICA methods the result are achieved from adaptive or iterative algorithms, which are time-consuming procedures. Another work was based on the nonlinear de-noising source separation (DSS) method [6]. This method is supposed when two images have independent sources and have different frequency components in the same locations. These conditions are the same as those exist when a source is contaminated by noise. Therefore, nonlinear de-noising might be used for source separation. The separation method used here is similar to that implemented in [6]. However, we believe that human visual perception uses different edge directions in the mixed subjects to separate them. Therefore, we improved the method in [6] which based on exact high frequency separation. As well known, wavelet analysis offers limited directional information in representing image edges when separable one-dimensional transforms are used for images. Minh N. Do and Martin Vetterli developed a true two dimensional representation, called contour let [7], which can capture the intrinsic geometrical structure that is key in visual information. Compare to the recent image representations this construction results in a flexible multi-resolution, l ocal and directional image expansion using contour segments. Moreover, sub sampling process in the wavelet transform change the geometric information of image details like edges. So, non-subsample wavelets are introduced for decomposing the image frequency components with better saving its geometric information. For comparing the results with [6], here we use the images that Mr. B. Luis. Almeidamade in his laboratory. He dealt with a difficult version of image mixture problem, corresponding to the use of onionskin paper, which causes a strong nonlinear mixture. The source and mixture images are shown in figures 1 and 2. More information about images is available in [1] and [2]. This paper is organized as follows: Section 2 explains the basic image separation method which is used in this paper. Section 3 introduces the proposed pre-processing methods. Section 4 presents separation method based on non-sub sampled wavelet and non-sub sampled contour let transform which has adaptive str ucture. Section 5 explains the experimental result. Section 6 has some discussions about the results. Section 7 gives the concluding remarks. The nonlinear image separation procedure based on de noising source separation [1] is based on wavelet transform, and uses very basic information about the sources and the mixture procedure. This information is based on two observations: First; the high frequency components (details) of common images are sparse. As a consequence, the wavelet coefficients from two different source images will seldom both have significant values in the same image location. Fig. 1 :Five source image pairs [1]. Second: Each source is more strongly represented in the image acquired from that side of the paper in which that source is printed than in the image acquired from the opposite side. The schematic representation of the separation method is shown in Figure 3. In this figure, the mixed images are first pre-processed by the following relation: where elements of Q matrix is the auto covariance of mixture matrix. This equation applies a linear transformation to the mixed sources. The nonlinear process is based on wavelet analysis which iteratively decomposes the approximation coefficients Aj(the low frequency component) at level j to four components (the approximation at level j+1, and the details in three orientations; horizontal, vertical, diagonal). Fig. 2: Five mixture image pairs after scanning [1]. components (the approximation at level j + 1, and the detail sin three orientations; horizontal, vertical, diagonal). After performing wavelet decomposition on mixed images for a certain number of levels, a competition is performed between the corresponding high frequency components from the two mixture images in each side of paper, according to following equation: are the wavelet coefficients of a given type (for example vertical coefficients at the first decomposition level) of the decomposition of the i th mixture image, x3à ¢Ã‹â€ Ã¢â‚¬â„¢i are the corresponding coefficients from the other mixture image, and a is a parameter that controls the strength of the competition. Fig.3: Schematic representation of wavelet-based separation method[1] This competition was applied to all horizontal, vertical and diagonal wavelet coefficients at all decomposition levels. The competition computes mask mi through a soft winner take all function [1], and then applies this mask to the wavelet high frequency coefficients of the mixture images, so that the coefficients are intensified in the image in which they originally were stronger and weakened in the image in which they were weaker. The separated images then will be synthesized using the wavelet coefficients compute competition in high frequency. In [1], one-dimensional discrete wavelet basis are separately used in horizontal and vertical directions. In the first step we assume the mixing procedure is a linear process and try to estimate the mixing matrix and implement the inverse matrix for separation. Although, we know the linear assumption is not completely right, however, it can be used as a pre-processing step to separate the mixed images. Since the source images are not available, the mixing matrix should be estimated through a statistical approach. The following approach is written for this purpose. If we show the source signals as S, mixture signals X and the mixing matrix as A, then we have: X= AS (4) In equation (5) we assume that the variables are zero-mean. This means we deal with the mean subtracted source and mixture images. From Eq (5) the autocorrelation matrix of mixed images is: From Equation (6) and (7) we could write: (8) (9) Since b>a, then only the plus sign is correct and from equation 6 we have : X1 + X2 = (a2 + b2) (S1 + S2)(11) A. First Pre-processing Method We assume that total energy of pictures before mixing and after that are equal. We use equation 11 and have some manipulation from these simple equations for a and b. a2 + b2 = 1 (12) (13) (14) B. Second Pre-processing Method We assume that when a packet of light emitting from scanner laser, b is the amount of light which went through the paper and a is the amount of light which reflect from first side of paper. In this method, we assume that, the amount of light which go through the paper and the amount of light which reflect back, together are constant. We have: a + b = 1(15) (16) But in this case, when we extract images, the contrast of images is high. For this effect we use modified form of this equation as below: a+b = 1.4(17) (18) C. Third Pre-processing Method We know from equation 5 that: (19) This equation has four undefined parameter and from equation 8 we have three equations. Assume that for normal deviation of mixture images and primary image we have: (20) This is the other equation to solve four undefined parameters. By solving(19),we can determine a and b. : (21) Where s1 and s2 are separated sources through a linear process. Fig.4: Result of implementing the proposed pre-processing method Since, we estimated the mixing matrix through non-exact assumptions it should be examined to show how it can separate the mixed images. Therefore we applied these three pre-processing method.We see that these three equation which derive from previous assumption has approximately the same extraction Figure (4-a) shows the mixed and processed images. From Fig4 b) we can see the proposed linear process 3 could approximately separate the mixed images. Although, s1 and s2 are not completely separated, we use the linear process as pre-processing step and those may be used for final separation through the nonlinear process that will be explained in the next section. The results of applying our pre-processing method to one pair of mixed images are shown in Fig. 4. The results show that the proposed method has partly separated the mixed images. The most important goal of this separation method is to obtain a sparse edge and contours of images that are placedin high frequency component of images. Wavelets for decomposition is not good [9] because when we use wavelets, in each level of decomposition, a down sampler shrink the size of the remainder and competition in high frequency is not exact and when we reconstruct image from that, blocking effect appear. Because assume the size of image is odd. In down sampling we have not an exact decomposition and in reconstruction, images dont have a good quality and appear some block. In first method we use NSWT which approve those blocking effect. This method has very short runtime and is acceptable for approximately all application. The other method is based on NSCT. This method is composed of pyramid decomposition and directional filter bank. Pyramid decomposition is shown in figure5 and directional filter bank is shown in figure 6. When we use these two decomposition at the same time we have a composed method which is shown in figure 7. Fig.5: Pyramid Decomposition Fig.6: Directional filter bank Directional filter bank have a good property that can describe diagonal line in pictures and if we use it for separation we have a better result. For each decomposed frequency based part, we use our well-known mask which is described before. We present an adaptive form of NSCT which is announced below. Fig.7: Combining two methods We first decompose in first level and apply separation mask. Then we reconstruct images and use correlation factor among them. If it is too low for example 0.01, extraction is good. If it is higher than some threshold we decompose image in further level and use separation mask. In this method, it is not necessary that we define decomposition level at first. NSCT has other good performance which is shift invariant. This property has no blocking effect. In this section we present experimental result from our method which are NSWT and improved NSCT. These two methods have an approximately complete separation result. First method has low runtime but in order to compare it with NSCT, the last one has a better separation result because we use directional filter bank and it could better separate high frequency in two images in every direction which we want. In NWST we use 6 and 7 level decomposition and since it has fast algorithm to decompose picture in wavelet form. In improved NSCT we use an adaptive form which it has little runtime and can separate in each direction we want. In figure 8 we show the experimental result for NSWT and in figure 9 we show the other one for NSCT. Fig.8: The result with NSWT Fig.9: The result with improved NSCT We see from the results that, our separation methods have better results in compare with the proposed methods in references. In our case, we derive very simple equations that can separate two mixture images linearly, which leads to a from the results that, our separation methods have better results in compare with the proposed methods in references. In our case, we derive very simple equations that can separate two mixture images linearly, which leads to a time-efficient algorithm. The two mainly proposed algorithms (NSWT and Improved NSCT) shows that by using preprocessing and these methods simultaneously, we achieve to really good results and our separated images, have absolutely good quality. In this paper we present a new preprocessing method which has a simple function and high precision in separating mixture images with linear form. Also we use two other separation rule that approximately separate images completely. NSWT has a good quality with a little runtime. On the other hand, NSWT which use directional filter bank has better effect in separation with approximately two level of decomposition. References [1] Mariana S.C. Almeida and Luis B.

Birth Defects Essay -- essays research papers

Birth Defects No one is immune to birth defects, yet not everyone is equally susceptible. Birth defects are not merely a medical problem. They have profound effects on the social and psychological well being of their family and friends. In the normal course of fetal development, cells migrate to their appropriate destination so that organs and limbs form where they should. Usually, the genes perform flawlessly, but mistakes can and do occur. Some of the most common birth defects results from the interaction between one or two abnormal genes out of 100,000 that make up who we are. This is caused by the genes parents pass on or effected by drugs and alcohol upon the fetus of a new born child. Down's syndrome, the most common genetic disease formerly known as mongolism, "occurs one in every six hundred births throughout the world" ( Storm 102). It is caused by chromosomal error, where there is an extra chromosome 21. Instead of have two chromosomes as does a normal individual, there are three. These children's features include up slanted eyelids, depressed foreheads, hearing loss, dental problems, poor speech development, heart disease and intestinal problems where surgery is required. Parents feel very helpless and guilty in many of these and similar situations, feeling as if they are abnormal. However most can learn to walk, talk, dress themselves and eat. Special work programs are available that can help the child reach their education level. Also these work programs help takes off the many stresses facing parents. They no longer have to go it alone. Tay Sachs disease is another selective genetic disorder that destroyed nerve cells. This causes mental retardation, loss of muscle control and death. Children who inherit an abnormal gene from both parents will inherit the decease. The carrier parents have one normal gene and one defective gene. Carriers of Tay-Sachs disease have no symptoms. " If two carriers have children, each child has twenty-five percent chance of inheriting the defective gene (both parents)" (Strom 174). These children are unable to produce an enzyme that breaks down fats in the brain and nerve cells. The cells become clogged with fat and prevent the cells from functioning normally. Within three to four years their bodies dies. Sandra vividly remembers how happy she was to have a baby brother and what a beautiful, h... ... be wrong. " Since two hundred and fifty thousand babies with birth defects of varying severity are born in the United States each year" ( Gravelle 6), it would be hard not to meet some of these people. In the past few decades, many strides have been taken to help understand the causes of such diseases with hope of treatments and cures. Also works of finding ways to help the parents cope with their emotional devastation have been taken as many accomplishments have been made. Parents are now finding ways to move past their anger and frustration and enjoy a loving relationship with their child. With a wider knowledge of information available and treatment to drug addits families can pull though. Caring for a child is a tough emotional and physical battle but should always be looked as a gift, these children have much to offer. Work Cited Darling, Jon. Children Who Are Different.
