Crystal meth addiction case study Essay Example

Crystal meth addiction case study Essay By the clip you are in simple you already have some cognition on drugs.They affect us in assorted ways, sometimes even personally.For Luke it became a personal issue. At foremost he began populating in the house of a crystal Methedrine nut to research the drug and see first-hand how it affected others. Originally he had no purpose of taking the drug, but after some clip he fell into enticement. Since the house he was populating in was full of crystal Methedrines and crystal Methedrine nuts it’s non surprising that this stoping up go oning. At first he would merely utilize it occasionally/recreationally. He felt that he could carry through more while utilizing it and that non-user were eldritch for non utilizing it. Harmonizing to him it was cheap, it helped him lose weight, and it was truly fun. â€Å"I felt originative, confident and productive.† ( Luke Williams ) We will write a custom essay sample on Crystal meth addiction case study specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on Crystal meth addiction case study specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on Crystal meth addiction case study specifically for you FOR ONLY $16.38 $13.9/page Hire Writer But after sometime this recreational drug became something he could non populate without. Luke so became an nut and began to see psychotic episodes and aggression. Because of crystal Methedrine he felt that everyone was out to acquire him and wanted to kill him. This is when he realized that he needed to halt. He went to a infirmary, but they offered him reasonably much no aid and were really unsympathetic. The topographic point where he used to populate kicked him out and happening a topographic point to remain became a hard undertaking. He lived with other crystal Methedrine nuts but they began to toss out on him, go forthing him with no pick, but to return place. His parents were really sort and took him in and helped him with his dependence. Learning to get by with the after effects of crystal Methedrine was difficult, but with the aid of his parents he is now populating a normal healthy life style. Although he no longer has that many friends he feels better, because now he doesn ’t have bad influences around him. He realizes how dense he was for taking crystal Methedrine and encourages others to neer seek it ( Williams ) . But where did this drug that destroys so many places and lives come from? This drug is a semisynthetic stimulation that has been around for a long clip. Crystal Methedrine was originally made by the authorities during World War II to assist soldiers remain awake. But after recognizing the after affects it had on the soldiers the authorities decided to censor it. Most of the crystal Methedrine in the United States comes from Mexican ace labs. Although people still do it here in the U.S. it’s normally inside their places. It’s really unsafe to do because of the chemicals involved which are really explosive. Crystal Methedrine comes in clear chunky crystals resembling ice and is most normally smoked. You can place Crystal Meth nuts by certain characteristics/behaviors that they exhibit. One of the first things that you will get down to notice is that they do non care about their personal visual aspect or hygiene. They continually pick at their hair and tegument which doing themselves awful looking sores. And they get hickeies that are difficult to acquire rid of. They are besides more likely to steal to pay for their dependence. Angry effusions and temper swings are really common in crystal Methedrine nuts. Other affects it has on the organic structure is raising the organic structure temperature to an unnatural degree, so high that the user could go through out or even dices. They lose appetite and weight dramatically. Dilated students, rapid oculus motion, anxiety, confusion, insomnia, insecure sex, violent effusions, and jerking are some of the after effects of crystal Methedrine. Users can go paranoid and hear and see things that aren’t really at that place ( hallucina tions ) . ( Ratini ) But why do people take this drug? What makes it so habit-forming? The powerful haste people get from utilizing crystal Methedrine makes a batch of people get aquiline right from the start. When it s used, a chemical called Dopastat ( chemical in the encephalon that inundations parts of it that regulate feelings of pleasance ) . Users besides feel confident and energetic. A user can go addicted rapidly and shortly finds he will make anything to hold the haste once more. As he continues to utilize the drug, he builds up a tolerance. That means he needs higher doses to acquire the same high. The higher the dose of crystal Methedrine, the higher the hazards. How make you acquire clean from such a powerful drug? How do you emancipate yourself from its Fe appreciation? Since most people who try crystal Methedrines are instantly addicted to it, it’s really hard to acquire clean from it. Actually it’s one of the hardest drug dependences to crush. Peoples who are addicted to crystal Methedrines normally can non crush the dependence on their ain and require professional aid. They either need a professional counsellor or drug intervention plan. For the first few hebdomads their organic structures will travel into backdown and they will merely be able to eat and kip because their head and organic structure are excessively tired to make anything else. They will experience anti-social and may hold violent effusions. During the whole backdown your organic structure is shouting for Methedrine. This is the hardest portion of acquiring clean. Then they go through a honeymoon stage where they feel ace confident. Most people have a backsli ding during this minute because of how complete confident they are. Then comes more depression and ennui after this. Finally they move into the accommodation stage where they begin to set to society and life in general. Staying clean is a day-to-day pick so it’s an on-going recovery. But how does this drug impact your religious life? Can you still have a close relationship with God while making Crystal Meth? No, you can’t†¦ Of class the Bible neer straight negotiations about drugs but that’s because they were non around during those yearss. But it does speak about dependences. All of the apostolic exhortations to stay sober-minded and watchful are designed to remind us that we must be argus-eyed against the traps of the Devil who seeks to entrap us through misrepresentation. ( 1 Peter 5:8 ) ( 1 Corinthians 15:34 ; 1 Thessalonians 5:4-8 ; 2 Timothy 4:5 ; 1 Peter 1:13 ; 4:7 ; 5:8 ) All of these texts talk about being sober and how can you make that if you’re so high you don’t even cognize your name? Sobriety is besides of import for supplication ( 1 Peter 4:7 ) . As Christians, our organic structures are non our ain, we have been bought with a monetary value which is the blood of Christ ( 1 Peter 1:17-19 ) ( 1 Corinthians 6:19-20 ) . Having bought us with His ain life if we pollute or harm our organic structures we desecrate the House of God ( 1 Corinthians 3:16-17 ) . So I guess all this answers the inquiry if you can or can’t be high and still see yourself a devoted Christian. In the beginning I mentioned that Luke began to utilize the drug because he was naive of its effects on the human organic structure and what crystal meth really was. After reading all of this information I feel like he would believe twice earlier seeking the drug. Peoples don’t normally think about the effects drugs have on your organic structure and neer halt to see the after effects. But if it is all written out for you and personal testimonies are added so it’s a batch easier to halt and be informed about the drug. This type of information would hold saved Luke from a batch of hurting, adversity, and danger. And all though he wasn’t a Christian, the texts from the Bible can be really helpful to Christian young person who are experimenting with different things. Many people are nescient and believe that merely seeking a drug one time will non impact them subsequently on and that they are merely traveling to make it one time recreationally. Unfortunately this is non the instance 99 % of the clip. Because crystal Methedrine is so strong people get addicted to it the first clip they try it and it is truly difficult to halt the dependence that is why Luke had such a difficult clip. To forestall things like this from go oning we need to talk out against drug maltreatment and inform people on what Crystal Methedrine and drugs in general do to your organic structure. We need to allow them cognize that they take control of your life and leave you worse than you of all time were before. And combating drug dependence is a womb-to-tomb thing because your organic structure will ever hunger the drug. Crystal meth ruins 100s of lives, households, relationships, and places each twelvemonth that is why we must talk out against it now. Luke didn’t have people in his life to inform him, but think about the people you know that are messing around with drugs ; have you taken the clip to inform them? Don’t allow them travel through all the thing s Luke went through. Plants Cited Petit, Aymeric. J Addict Res.

Context Clues and Literacy ESL Reading Lesson

Context Clues and Literacy ESL Reading Lesson One of the main challenges of any English reading skills class is that students tend to look up, or even insist on looking up, each word they do not understand. While this desire to understand everything is certainly laudable, it can be damaging in the long run. This is because students will begin to tire of reading if they are constantly interrupting the process to find another word in the dictionary. Of course, the use of e-readers might make this a little less bothersome. However, students need to realize that reading in English should be like reading in their own language. The use of contextual clues can be one of the best ways to improve students reading skills. Realizing that a text can be understood in a general sense by using contextual clues can go a long way towards helping students cope with increasingly difficult texts. At the same time, the use of contextual clues can also provide a means by which students can rapidly increase their existing vocabulary base. This lesson provides a number of pointers helping students identify and use context to their advantage. A worksheet is also included which helps students recognize and develop the skill of contextual understanding. Context Clues Reading Lesson Aim: Increased awareness and usage of contextual reading clues Activity: Awareness raising concerning the use of contextual clues, followed by worksheet practicing contextual reading Level: Intermediate - upper intermediate Outline Write this example sentence on the board: Tom decided that he desperately needed the glockum if he were to solve the problemAsk students what they do if they are reading an English text and do not understand a specific word.Ask students what they do if they are reading a text in their native language and do not understand a specific word.Ask students what glockum means.Once students have established that they dont know what a glockum is, ask them to guess at what it might be.Ask students what part of speech a glockum is (i.e. verb, noun, preposition etc.)Have students explain how they arrived at their guesses, which clues did they use?Explain the concept of reading in chunks i.e. looking at the text surrounding the unknown word for clues.Show them an article from an advanced level magazine (Wired, National Geographic, The Economist etc.)Ask students to identify the probable vocabulary areas that may be used in the example article.Explain the importance of activating vocabulary by fir st quickly glancing at the text to be read. This idea is very important as the brain will begin to focus on related concepts thus preparing the student for what is to be read. Point out that by using all of these clues (i.e. chunking, part of speech, logical deduction, vocabulary activation), students can arrive at a much fuller understanding of difficult texts - even if they do not understand each wordHave students divide into small groups and complete worksheet. Reading Clues Deduction - What does the sentence concern? Which words does the unknown word seem to relate to?   Part of Speech - Which part of speech is the unknown word? Is it a verb, noun, preposition, adjective, time expression or something else? Chunking - What do the words around the unknown word(s) mean? How could the unknown word(s) relate to those words? - This is basically deduction on a more local level. Vocabulary Activation - When quickly skimming through the text, what does the text seem to concern? Does the layout (design) of the text give any clues? Does the publication or type of book give any clues to what the text might be about? Which words can you think of that belong to this vocabulary category? Make logical guesses about the meaning of the unknown words in the following paragraph. Jack quickly entered the didot and cleaned the various misturaes he had been using to repair the wuipit. He had often thought that this job was extremely yullning. However, he had to admit that this time things seemed to be a bit easier. When he finished, he put on his redick and went back to the study to relax. He took out his favourite pipe and settled into the beautiful new pogtry. What a fantastic schnappy he had made when he had bought the pogtry. Only 300 yagmas! What could a didot be? What part of speech is misturaes? If Jack used the misturaes to repair the wuipit what do you think the mistraes must be? What could yulling mean? - What part of speech is often used with an ending -ing ? Which synonym could be used for yulling ? fundifficultexpensive What type of things do you put on? Based on the above question, what kind of thing must a redick be? Is a pogtry used inside or outside? Which words let you know that the pogtry was cheap? What must yagmas be? ClothesCigarette typeType of money

How did the struggle to resist segregation create a sense of African Essay - 1

How did the struggle to resist segregation create a sense of African American community, what purely African American institutions, cultural expressions, and po - Essay Example Myriads of blacks heroically resisted ‘white domination’, often jeopardizing their own lives. It is not possible to know the numbers of the African-Americans segregated by Whites were men and women who had confronted by some blatant acts of ‘bravery’, such as walking conceitedly down the roads or talking back to Whites instead of quitting. Anti-racial, socials integrity, desegregation, and even ‘racial equivalence’ enjoyed huge support amid leftists than integration. Even though black civil rights protesters had always stresses on ‘desegregation’ (Robin et. Al 1996). In nearly all white liberal spheres ‘cultural integration’ came to represent solving the Negro problem by carrying black people into previously all-white bodies (Robin & Earl 2005). Leftists, on the contrary, regardless of their beliefs, always struggling for ‘racial integrity’ in terms of taking racial discrimination separately – one of the opportunity for entrepreneurship – so as to create a more dominant challenge to ‘community rule’. From the beginning, they resisted to create systems which guarantee the equal rights for every one, irrespective of class or nation, to live as full human beings (Robin 2002). The split continued to be ever-lasting in 1905 when W. E. B. Du Bois1 established, with William Monroe Trotter who was a detractor of Washington, the whole black â€Å"Niagara Movement†2 (Robin 2002). With the organized challenges by movements like the National Association for the Advancement of Colored People (NAACP3) and Universal Negro Improvement Association (UNIA4) and their personal insubordination to Jim Crow5, African Americans embraced enriching their cultural life of, mainly, non-political demonstration against ‘white domination’ that infused all divisions of black life (Robin 2002). And in no more than the next twenty years, the NAACP staged a harmonized approach of legalized encounters, taking provinces and states to court to execute

The Latest Advances in Technology in The Recruitment Process Essay

The Latest Advances in Technology in The Recruitment Process - Essay Example The influence of new technologies such as social networking, Web 2.0 and e-methods are growing day by day in human life. For example, the recent Arab revolutions are believed to be the contributions of social networks. According to modern principles of communication, more ideas are communicated nonverbally than verbally in a face to face communication process. New technologies are providing enough options for face to face communication in the virtual world so that people can interact in virtual world as effectively as in real world. (Network Theory And Analysis, n.d.) Social networks need not introduction even among ordinary people because of the huge popularity of these interactive communication channels among them. Generally speaking, social networks are â€Å"web-based services that allow individuals to construct a public profile within a bounded system, articulate a list of other users with whom they share a connection, and view and traverse their list of connections within the system† (Boyd, 2007). On the other hand, Web 2.0 is only at its introductory stage now and therefore it is not necessary that all people are aware of it. Web 2.0 is actually the second generation of WWW. It was introduced in 2004 to provide more facilities to the internet users. In short, Web 2.0 is a web platform intended to provide â€Å"much more dynamic and interconnected surfing experience to online communities. Because most Web 2.0 features are offered as free services, sites like Wikipedia and Facebook have grown at amazingly fast rates† (Web 2.0, 2008). The influence of advanced technologies is growing on business as time goes on. The influence of computers and internet on business needs no explanations now. All the aspect of modern day business in controlled by internet related technologies. For example, recruitment is one area in which advanced technologies started to exert more influence. Social networks and other modern day web based technologies are used ex tensively for the recruitment process now. This paper analyses the impacts of new technologies upon recruitment process, benefits and drawbacks of using new technologies in recruitment process etc. Impacts of new technologies upon recruitment process Hunt (2009) has argued that â€Å"people are on social networks to connect and build relationships†(Hunt, 2009, p.2). On the other hand, Shih (2009) has mentioned that â€Å"online social engagements transform the relationships between the companies and customers from one sided to two sided† (Shih, 2009, p.6). Relationship building is the core of every business activity now and recruitment process is also not an exception. Social networks can be used effectively the recruiters to build meaningful relations with job seekers. â€Å"The IES survey of 50 organisations using e-recruitment reported that the primary drivers behind the decisions to pursue e-recruitment were to: improve corporate image and profile, reduce recruitm ent costs, reduce administrative burden, and employ better tools for the recruitment team† (Kerrin & Kettley, 2003). Extensive use of web based technologies in corporate matters will definitely improve the image of an organization.

Business cultural Dissertation Example | Topics and Well Written Essays - 14000 words

Business cultural - Dissertation Example 115). Strengthened by the maximum gross domestic product (GDP) per capita within North African region and government expenditures going beyond 48 billion USD every year, Libya has rapidly turn out to be one of the most lucrative markets in the region for a wide range of products and services. As foreign businesses assess the prospect of entering this potentially productive market, endurance, a dependable associate and profound understanding of the political as well as business setting are significant assets that should come with any future venture. Background As Libya carries on to recover from the Qadhafi era, businesses will certainly come across a number of the similar challenges many Libyans have coped with for years. From a functioning point of view, these aspects repeatedly disrupt the best of project management attempts and exponentially raise the level of endurance essential to function successfully (Bayoud et al, 2012, p. 145). Nonetheless, in a culture focused on associatio ns, the value of a dependable associate with the necessary understanding of the Libyan market cannot be devalued. Looking for an associate with the cultural understanding and continuing political as well as business dealings required to get things done can usually indicate the difference among achievement and collapse. While this business setting will certainly modify during the coming months as the lately nominated General National Congress (GNC) carries on to deal with its parliamentary priorities, companies must be responsive towards existing regulatory requirements. Businesses should as well be aware of a decision linked with â€Å"new customs tariffs issued by the GNC’s predecessor, the National Transitional Council† (Joffe, 2011, p. 240). The general charge of customs duties shall be five percent, with the exception of some particular products that charged higher duty rates starting from 10 percent up to 30 percent. There are some offered within this decision how ever, up till now, a thorough customs tariff chart has not yet been published. While many may consider the inherent challenges of the existing Libyan market as daunting, there are still some companies from around the globe who are recognizing the bright prospects at hand once the problems are being taken care of. Following a year of inconsistency and 42 years of dictatorship, Libyans are dedicated towards helping the country to apprehend its potential and identify the part for foreign business during the process (Adetunji, 2011, p. 209). With the proper leadership, global businesses can do well in Libya and deliver products and services that the financial system requires as it goes to the next level. For companies who can afford to be enduring, who can operate with a dependable local associate and stay at the forefront of political and business

Study of Hydrodynamic Forces on Multiple Cylinders in Waves

Study of Hydrodynamic Forces on Multiple Cylinders in Waves Introduction In the recent years, there have been increase in demand of production in the offshore industry. The wide market scale of offshore structure business in oil and gas production attracts interest for investors. Offshore structures are stationary structures located in the marine environment for production of natural resources such as wind turbine for generating electricity, FPSO (Floating Production Storage Offload) for crude oil extraction and drilling for drillships. These offshore structures can be either fixed or freely floating. Floating offshore structures/platforms will be using mooring system or dynamic positioning method to float and hold its position in place. Many challenges are faced to withstand the position of the offshore structures due to seakeeping and wave load problems. As technology advance over the years, new implications and investigations are being carried out for offshore structures to to deal with seakeeping and wave load problems. The implication of hydrodynamic force acting on an offshore structure became important due to various wave loads and interactions might affect the results of hydrodynamic forces greatly. The hydrodynamic forces determine how structures float with varying wave frequencies, wave height and etc. Large offshore structures such as semi-submersibles, offshore wind turbines and SPAR are often being investigated to improve their efficiencies by changing their shapes or dimensions. Large offshore cylindrical structures would affect hydrodynamic results due to their wave diffraction and radiation forces. Therefore, in this literature review, investigations of hydrodynamic forces on multiple cylinders are being studied. In order to understand how the hydrodynamic results vary, floating bodies with varying distance are being placed in ideal fluid, where hydrodynamic interactions will cause the influence by the scattered waves and the wave load will differ greatly by the presence of the neighbouring cylinders. Thus, to obtain accurate results, these hydrodynamic interactions are investigated from theoretical predictions, software simulation analysis and model testing. The development of computer with memory capacity and computational speed increases with the advance in technology. The use of these software simulation analysis helps to analyse the wave interactions between multiple floating bodies in an ideal fluid. The software is dependant on the development of hydrodynamic theories. By using linear wave potential theory, the diffraction and radiation forces could be calculated. Hydrodynamic Interaction phenomena Studies of hydrodynamic interactions of multiple bodies have been on going over the past few decades. Hydrodynamic interaction created are due to wave actions the presence of neighbouring structures. A free floating body may experience six DOF (Degree of Freedom) due to surrounding condition, where three are translations (Surge, sway and heave) and three are rotations (Roll, pitch and yaw). Vertical and longitudinal motions are the primary motions which are often experience by offshore structures.[1] The interaction phenomena is due to diffraction and radiation forces acting on the structures and forces created by the structures. The velocity components and the motion of each body can be obtain by the integration of equation of motion. The interaction phenomena between two or more floating structures plays important role on the performance of floating structure systems. It depends on the sepetration distance between the floating bodies and also on the direction of flow with respect to the centerline of two floating bodies.[2] This phenomena can be investigated by using both theoretical and experimentally(Model Test). For experimental, using a full scale model tests are desirable but there are limitations due to controlled conditions and the high cost of production. Therefore, the need of associated computation tools for analysing these hydrodynamic forces to attain fast and accurate results. The complexity of multiple bodies solution increases with the amount of elements.(Research_3) Thus, the use of numerical method is highly recommended in this studies. http://www.ias.ac.in/sadhana/Pdf2004Dec/Pe1236.pdf [1] http://www.dtic.mil/dtic/tr/fulltext/u2/a254627.pdf [2] Potential Theory The knowledge of motion and wave induced forces of offshore mainly involves the structural design and its operation. Offshore structures in sea environment usually encounter environmental loads such as gravity, waves, wind and current. These are the basic information needed to evaluate the interaction of structures through the use of potential theory.(G. Moe, 1996) Potential theory can use to find out the general aspect of fluid flow problems in conjunction with Laplace equation. To satisfy the solution of the Laplace equations, boundary conditions of the fluid are set. Hydrodynamic forces in waves consist of radiation and diffraction forces where velocity potential is the key component to satisfy the Laplace equation. Radiation and Diffraction Problem Hydrodynamic forces is made up of diffraction and radiation forces. These forces includes the 6 degree of freedom that arises from the interaction of linear waves against any floating structure. In addition, these forces will provide information of hydrodynamic properties of floating structures, such as damping coefficient,added mass and wave excitation forces. The fluid must be assumed to be inviscid, incompressible and irrotational. Currently, there have been numerous theoretical and numerical studies on these problems. As the technology advances, researchers have obtained significant results on the phenomena, which made the study for these problems, such as structure and wave interactions, stability of floating structures aon going research. Diffraction Force Diffraction force is the pressure forces acting around the each structure, but due to multiple bodies and interaction of several bodies, the scattering will affect the results of incident wave. For free surface problems with the Laplace equation as the governing equation, a first order or a second-order boundary condition can be obtain using a linearized free surface boundary condition Radiation Force Boundary Conditions Governing Equation The motion response of a structure will cause the fluid to oscillate, hence creating pressure fields in the fluid. In order to capture the motion response and the surrounding pressure fields, velocity potential will be imposed. In addition, there are boundary conditions critition to be met. Drag forces are not being considered in the radiation and diffraction problems as it only occurs in slender body phenomena. With the assumption of having the structure placing in an ideal fluid with zero forward speed. In an ideal fluid condition, the fluid is irrotational and incompressible. The radiation condition should also be satisfied as it is to ensure that the waves propagate away from the structure. From the potential flow theory, it is made known that the velocity potential must satisfy the Laplace equations. Thus, the 3 boundary conditions mention below must be satisfied. Body surface The normal component of the fluid velocity is equal to the normal component of the heave force velocity Seafloor The normal component of the fluid velocity equal to zero Water surface The fluid pressure is equal to the atmospheric pressure and fluid particles will always remain on the free-surface. Pressure will be constant across the free surface. These equations mention below will show the governing equation imposed on radiation and diffraction problems.(Page 44) The velocity potential, along each component(x, y and z) satisfies the Laplace equation in the fluid domain, The free-surface condition, Boundary condition on the sea floor, Boundary condition on body surface, Where k is depends on the motion (six DOF) that the body surface is expose to and nis the unit vector normal to the body surface. Solving Boundary Value Problem The boundary conditions are all set in conjunction with velocity potential. The expression of linear hydrodynamic forces is derived from direct integration of the fluid pressure over the boundary of a body. By using the Green’s theorem, part of the forces can be obtained with the solving the scattering potential. Defining the field point at any point and the source point for circulation, rotation and vorticity, the Green funtion will be presented in the form, Where Equation 7 expresses the source potential as a summation of a source in the finite fluid and an image source above the free surface condition where . This shows that there will at . Equation 8 expresses the source potential is a summation of a source in infinite fluid and an image sink above free surface when . This satisfy the free surface condition where velocity potential equal zero on . Therefore, the solution of the velocity potential for a problem (e.g. force heave) can be written as This source function is given for infinite water depth problem where is called the Green function. By using the Bernoulli’s equation, the total pressure could be fully derived with the use of velocity potential and the body motion amplitudes. Therefore, linear forces and moments are obtain from, We can consider component potentials such that the summation of hydrodynamic forces and moments are Where it is split into two components: the wave excitation force due to diffraction and forces due to radiation force(In terms of added mass and damping coefficients). Given we want to find the force at mode j. The linear forces, also known as the first order wave excitation force, the force for mode j is denote as From Green’s theorem, applying it to and a component of the radiation potential, we have It is show that those integrals on the seabed, over the free surface and at the far field disappeared due to the boundary conditions for and on these surfaces. Therefore, upon substituting the equation of boundary conditions, the Haskind relation follows in the form of By using the equation of motion, the diffraction and radiation problem will be solved. Calculation of Hydrodynamic forces The boundary value problem is solve, therefore the forces and moments can be evaluate. Panel method is use to solve the boundary value problem which is based on potential theory. Assumptions such that the wave amplitudes of the fluid is small as compared to the cross-sectional dimensions of the body are made. The panelling of the structure is done by plane quadrilateral elements in three dimensional problems. http://www.academia.edu/6937922/Computation_of_Ship_Hydrodynamic_Interaction_Forces_in_Restricted_Waters_using_Potential_Theory The solution procedure can be generalized to any modes of motion, where added mass and damping matrix could be found. Solving the diffraction problem can be done by using the boundary condition (equation 5) where is the incident wave potential. From these solutions, we are able to derive the wave excitation loads such as wave excitation forces (surge, sway, heave) and wave excitation moments (roll, pitch, yaw). Therefore, solving the equation of motion and calculating the flow details such as hydrodynamic forces, by using the expression for velocity potential in terms of a three-dimensional source distribution. Past Researches Overview WAMIT Wamit software is a diffraction/radiation panel program developed to analyse the linear interaction of surface waves with several different types of submerged and floating structures. For this analysis of interaction, WAMIT uses a three-dimensional panel method and also following some theoretical method. By using this software, it can help to define the conditions of the interactions such as, finite or infinite water depth, structures location on the free surface, mounted on the seabed or submerged and whether the structures are fixed or freely floating with the motion of six degree of freedom. The fluid flow is assumed to be ideal and time harmonic. WAMIT is able to deal with both first order and linearize analysis which includes second order forces. WAMIT is able to focus on the hydrodynamic interaction of multiple body with any restriction of condition of fluid environment. The use of integral equation obtained by Green’s theorem will help solve the diffraction and radiation velocity potentials on the body wetted surface. WAMIT will be able to evaluate the following quantities: Hydrostatic coefficients Added-mass and damping coefficients for all modes Wave excitation forces and moments using the Haskind relations, or directly by pressure integration from the solutions of diffraction or scattering problems. Motion amplitudes and phases for a freely floating body Forces restraining a body which is freely floating in some but not all modes Hydrodynamic pressure and fluid velocity on the body surface/fluid domain Free-surface elevation All component of the drift force and moment by momentum integration over a control surface Horizontal drift forces and mean yaw moment by momentum integration in the field All components of the drift force and moment by local pressure integration over body surface Drift force and moment in bidirectional waves Theoretical Method The method use by WAMIT will be a panel program designed to solve boundary-value problem for the interaction of waves phenomena with the pre-defining the bodies in finite or infinite water depth. Viscosity will not be considered. The time harmonic solutions are being solved for a given steady state incident wave field which is assumed to be represented by a superposition of a particular frequency components in the absence of the body. The boundary value problem will be used in conjunction with the integral equation using Green’s theorem. These integral equation will be solved by panel method for the unknown velocity potential or strength source of the body surface. These integral equations of theoretical method could be found in .

Poem Analysis of Meeting at Night, by Robert Browning Essay -- Poetry

Poem Analysis of "Meeting at Night," by Robert Browning Robert Browning's poem "Meeting at Night" is essentially a narrative of a man who is journeying to meet his lover. The man recounts his journey as he undertakes it, mentioning or observing different portions of the trip, each in turn. One by one, he briefly describes his surroundings as he passes by them, merely noting them as if they bear only fleeting significance to him. However, although his descriptions are unpretentious and abruptly forgotten as he continues onward toward his goal, each line of the poem contains striking imagery. In fact, it should be noted that this poem consists entirely of imagery. Every line depicts a scene of the landscape that Browning's narrator encounters; that is, at least, until he finally reaches his destination, when his focus is diverted to his lover. Throughout the entire poem he offers no personal insight or reflection on his situation, and he instead is content to merely report his perceptions and observations as they come and go.
