Sensory Disabilities Essay Example | Topics and Well Written Essays - 250 words

Sensory Disabilities - Essay Example the blind man crossing the road alone is a sign of bravery and his this act is also showing that he is a part of the normal society of Canada, but, still it is quite dangerous and he can be the victim of a terrible accident, unlike the normal people who are able to see the vehicles on the road before crossing it. A solution to this problem can be the awareness among people that they should take care of disabled people and help any blind man crossing the road alone. The drivers should also be careful and not drive too fast. If the car and bike drivers drive fast and an unexpected blind man is seen crossing the road, the vehicle will not be able to bear the prompt break by the driver and can slip and slide over the snowy slippery road and cause a dreadful accident. Hence, such precautionary measures and care should be taken to avoid any harm to the disabled people, and encourage them to be a part of the normal Canadian

National Gallery Still Life Assignemnt Essay Example | Topics and Well Written Essays - 500 words

National Gallery Still Life Assignemnt - Essay Example Still life painting began in the 16th century and became a serious art form in the 17th century when artists began to realistically dramatize their works (Charles 49). Most still life painting of the early painters got used to convey messages about the futility of worldly life and material decay. Early painters of still life centralized around moral and religious themes when painting their work. The church represented a strong influence upon early still life painters. An analysis of Michelangelo Merissi Da Carravaggio ‘supper at Emmaus’ is of great use in understanding still life painting. ‘Supper at Emmaus’ is an example of a still life painting carried out in 1601 by Caravaggio (Charles 68). In the painting, the artist includes arrangement of fruit, wine, bread, and cooked fowl. The table in the painting gets used to lay out the still-life meal. A closer look at the fruit basket in the painting will reveal to the viewer of its precarious position at the table’s edge. The painting depicts a story from the bible where Jesus Christ is said to have appeared incognito to two of his disciples who failed to recognize him after his resurrection. Later, Christ appeared to the disciples at a supper meal in Emmaus where he blessed the meal and shared it to them. When the disciples began to recognize him, he disappeared. Caravaggio’s painting depicts the moment when Christ blesses the bread, and in turn revealing his true identity to the two disciples. Christ is shown beardless in the painting. The artist provides a further emphasis on the still life meal on the table. The gestures and expressions of the disciples reveal their intense emotion at recognizing Christ. The depiction of a beardless Christ at the table may be confusing to the viewer at first instance of viewing. The viewer might think that Christ is just any other person or disciple at the table. This depiction of Christ makes the viewer to feel a participant in the

Amtrak Essay Example | Topics and Well Written Essays - 1250 words

Amtrak - Essay Example The construction of the Interstate Highway System greatly enhanced the appeal of road transportation, both for passengers and freight. Air travel became the dominant public carrier mode for intercity passenger travel. In addition, the national government found itself in the passenger train business (Adrian, 1977). Early in U.S. history, passenger travel was often difficult and uncomfortable. With the coming of the railroads, people gained the ability to travel farther and faster than most had ever imagined. Although the early passenger trains were not very comfortable, track and equipment gradually improved. The railroads helped to link different sections of the country and speeded the settlement of the western United States. The railroads were among the first big businesses in the United States, and major railroad executives became celebrities (Adrian, 1986). By 1900, a traveler on a first-class train could expect to find good food, a library, a barbershop, and the company of prominent individuals from the worlds of business, politics, and entertainment. The passenger train for a time appeared to occupy a secure place in society (Beebe, 1976). Any organization must strike a balance between stability and change, and transportation organizations are no exception. Changing public preferences, new technologies, population movements, and rising or falling prices of supplies may force an organization to make drastic changes in many aspects of its operations. Although transportation organizations must change at times to keep pace with shifting external conditions and to manage internal pressures, a degree of organizational stability is essential. For example, transportation systems require substantial public and private investment in fixed facilities, vehicles, and personnel training. A high degree of instability risks rendering those investments irrelevant or wasteful.( Bowersox,1989) Amtrak: Amtrak has faced considerable difficulties in trying to achieve the desired balance of stability and change needed to maintain credibility as a transportation mode. Beginning with uncertain and conflicting goals, the Amtrak system seemed to be destined for chaos rather than predictability. Repeated attacks by the Reagan administration, conservatives in Congress, and bus companies seemed to foretell large cutbacks or even termination. Moreover, the nation's passenger train system was in relatively poor condition at the time of Amtrak's creation; maintaining the conditions that existed in 1971 would hardly give the system credibility. (Amtrak, 1996) Nonetheless, the Amtrak system has managed to achieve a substantial degree of stability, coupled with significant change - much of it in the nature of improvement. The political turmoil surrounding Amtrak stands in stark contrast to the substantial operational consistency and improvement that the system has achieved. Amtrak Logistic and supply chain Route: One of the fundamental features of any transportation system is its overall reach, the extent of its routes, the number of access points available on those routes, and the utilization of the routes. A system that experiences rapid expansion of its overall reach is likely to be faced with challenges. Quick expansion brings

Management seminar Essay Example | Topics and Well Written Essays - 2000 words

Management seminar - Essay Example Common issues such as linkages between appraisals and increases in salary act as key determinants of the best system for the hospital relative to its overall goals and objectives as a healthcare institution. As part of the conclusion, the Mater Hospital administrators lack the required organization to ensure sustainability of such a medical institution as depicted by the current appraisal system. Assertively, the appraisal systems are equally significant as the reward and retention systems that appear to carry more weight in human resource management and it would be interesting to learn how organizations can link these systems for advanced efficiency. Accordingly, concrete talent management programs form the foundation for talent attraction and retention; however, most corporations overlook the fact that the leadership and management are the core overseers of talent, but through the set programs. Relatively, the control of talent and retaining employees is essential to the development and triumph of any corporation; moreover, the talent initiatives should go hand in hand with engagement, evaluation and reward strategies, as part of organizational cultures (Allen 2010). However, most of the discussions under human resources aspects focus on attraction, reward and retention with only a few giving sub-standard attention to appraisal and evaluation systems that are equally significant. Assertively, the aim of the case analysis on Mater Hospital is identifying the application of the appraisal systems and the depth at which they influence a certain organization. The foundation of the discussion is the bungling appraisal system in the h ospital, with the analysis focusing on Donald Kirkpatrick’s Learning and Training Evaluation theory. The Mater Hospital has multiple staff members from healthcare professionals, caregivers and support employees under administrators and supervisors that ensure quality and compassion in all areas. As per the hospitals values and

HIV Pandemic Essay Example for Free

HIV Pandemic Essay We are entering the third decade of what may be the most devastating epidemic in human history: HIV/AIDS. The HIV/AIDS Pandemic is a large-scale epidemic affecting more than one country. AIDS was first clinically diagnosed in the early 1980s but retrospective diagnosis suggests it existed well before this date. AIDS is a syndrome, which develops from an impaired ability to fight diseases. It undermines the body’s defenses against viruses, infections and malignancies. Here, we describe the origins and evolution of these viruses, and the circumstances that led to the AIDS pandemic. Pandemic Assignment Since scientists identified the HIV as the cause of AIDS in 1983, it has spread insistently, causing one of the most harmful pandemics ever recorded in human history. However, concerted global efforts to fight the pandemic are making a significant difference. More than nine million people living with HIV in low and middle-income countries now have access to life-saving antiretroviral treatments. Overview Human immunodeficiency virus (HIV) invades the body through the exchange of certain body fluids. The virus invades cells such as T helper cells and begins to replicate itself in the human body. Acquired immunodeficiency syndrome (AIDS) of humans is caused by two lentiviruses, â€Å"HIV-1 and HIV-2; HIV-1 accounts for the majority of infections in the world, and has at least 10 genetic subtypes† (Lamptey, Wigley, Carr, Collymore, 2002). Both HIVs are the result of multiple cross-species transmissions of simian immunodeficiency viruses (SIVs) naturally infecting African primates. However, as according to Sharp Hahn (2011), one transmission event, involving SIVcpz from chimpanzees in southeastern Cameroon, gave rise to HIV-1 group M—the principal cause of the AIDS pandemic† and noted that by â€Å"tracing the genetic changes that occurred as SIVs crossed from monkeys to apes and from apes to humans†. AIDS Pandemic and the Efforts to Stop HIV/AIDS According to Merson â€Å"on June 5, 1981, few suspected a pandemic of AIDS when the Centers for Disease Control reported five cases of Pneumocystis carinii pneumonia (PCP) in young homosexual men in Los Angeles† (2006). Morbidity and Mortality Weekly Report (MMWR) reported that all the men had other unusual infections as well, indicating that their immune systems were not working; two had already died by the time the report was published. In a timeline created by AIDS. com, â€Å"this edition of the MMWR marks the first official reporting of what will become known as the AIDS epidemic† (2014). Although â€Å"after pandemic HIV-1 first emerged in colonial west central Africa, it spread for some 50 to 70 years before it was recognized† (Sharp Hahn, 2011) because phylogenetic and statistical analyses have dated the last common ancestor of HIV-1 to around 1910 to 1930. For a while the American government completely ignored the emerging AIDS pandemic. The first attempt to treat HIV was in â€Å"September 1986, when early results from clinical trials involving AZT (zidovudine) – a drug that was first investigated as a cancer treatment – showed that it might slow the attack of HIV† (AVERT, 2013). Although AZT could slow progression to AIDS in HIV positive individuals with no symptoms, a year’s supply for each person would cost around seven-thousand dollars and many did not have adequate health insurance to cover the cost. In 1995, â€Å"FDA announced that the drug 3TC (lamivudine) had been approved for use in combination with AZT in treating AIDS and HIV† (AVERT, 2013) after a number of studies had shown that HIV could quickly become resistant to AZT and that the drug had no benefit for those in the early stages of the disease. On April 5th 1990 Ryan White, schoolboy who had become infected with HIV via a blood transfusion for his haemophilia, died. He was known for his fight to return to public school after he was banned due to fears of spreading of AIDS to other children. â€Å"Following Ryan’s death, the American government implemented a new programme named after him – the Ryan White Comprehensive AIDS Resources Emergency (CARE) Act† (AVERT, 2013). Its aim was to improve the quality and availability of care for low-income, uninsured and underinsured individuals and families affected by HIV. In 2000, the government funded programs such as needle exchange services and abstinence-only education and in 2001 the Centers of Disease Control (CDC) set a goal to halve the number of people infected with HIV each year in the USA to 20,000 by the end of 2005 but by 2003 it was already clear that the CDC’s goal would be missed, the number of new infections had shown no sign of declining. In 2006, President Bush signed the reauthorisation of the Ryan White HIV/AIDS Program, â€Å"since its creation in 1990 the program had provided federal funding for thousands of Americans living with HIV/AIDS unable to pay for their treatment themselves† (AVERT, 2013). In 2007, raltegravir – was approved by the FDA which according to AVERT â€Å"Raltegravir was the first of a new class called integrase inhibitors† and â€Å"the significant progress in treatment proved to be particularly important to thousands of HIV positive Americans whose treatment had been failing due to drug resistance (2013). It was believed to provide extended years of meaningful survival to patients. In July 2010, â€Å"the USAs first HIV/AIDS Strategy was released† (The White House Office of National AIDS Policy, 2010) and reducing new HIV infections was included as one of the Strategys three core aims. According to AVERT (2013), â€Å"in order to reduce new infections without an increase in funding, the Strategy recommended that HIV prevention efforts be intensified in the communities where HIV is the most heavily concentrated†. MedlinePlus concluded that â€Å"there is no cure or vaccine to prevent HIV/AIDS, but early detection through HIV testing and treatment can frequently turn this fatal disease into a manageable chronic disease† (2009). The HIV-1 pandemic is a complex mix of diverse epidemics within and between countries and regions of the world. â€Å"AIDS remains the fourth leading cause of death in low-income countries† (International AIDS Vaccine Initiative, 2014). While there will never be a solution to HIV and AIDS, a preventive vaccine would do a great deal to curb the pandemic. But unfortunately, the problem with developing a vaccine is that the HIV genome mutates very quickly. Stowell (2006) explains that all organisms vary a little throughout the centuries. The HIV genome mutates around 1000 times more quickly than the human genome around 1000 times more mutations accumulate in a single year, relative to the length of the genome. Antiretroviral treatment has transformed AIDS from an inevitably fatal condition to a chronic, manageable disease in some settings.  Johannesburg (2010) cited The Lancet medical journal, which published a study that predicts that by 2031 – about 50 years into the HIV epidemic – annual new HIV infections will be roughly halved to about 1. 2 million.

Microsoft Surface Table: 3D Modelling and Touch Controls

Microsoft Surface Table: 3D Modelling and Touch Controls Background and Context Three Dimensional (3D) Modelling is the process of creating a 3D representation of any surface or object by manipulating polygons, edges, and vertices, in simulated 3D space ­1. 3D modelling is used in many different industries, including virtual reality, video games, TV and motion pictures. 2A 3D modelling software generates a model through a variety of tools and approaches including: Simple polygons. 3D primitives simple polygon-based shapes, such as pyramids, cubes, spheres, cylinders, and cones 3Spline curves a curve that connects two or more defined specific control points. 3NURBS (non-uniform rational b-spline) Computationally complex, smooth shapes designed by bezel curves. Scope and Objectives In this project, the 3D model produced, was the 5G Innovation Centre at the University of Surrey. The final version of the prototype is supposed to be a model of the whole University campus, which would be able to display the temperature, noise levels, and a few other statistics in every single area on the map. In order to record data, an IoT Desk Egg4 was created. This Desk Egg is a multi-sensor suite with feedback mechanisms and wireless communication capabilities. Using this Desk Egg, environmental data, such as light, sound, temperature, noise, humidity, dust density are measured and recorded. Separately, these recordings have limited value, but when combined, and analysed in aggregate, the sensors provide a rich context of its immediate surroundings. 5The objective of this project is to enhance the model with touch navigation capabilities, similar to 3D navigation on a mobile phone or tablet. The current model is constructed for a Samsung SUR40 touch table, running Microsoft Surface. The model has been implemented using PixelSense and in addition, Microsoft Surface Game Studio 4.0 and the Window Presentation Foundation (WPF). To go about enhancing the model, investigations would have to be established, on what changes would be involved to implement touch navigation, before implementation and testing of the aforementioned varieties. Introduction[SO1] Microsoft PixelSense 6Microsoft PixelSense orientation capabilities are used and seamlessly integrated into the application, which also supports multiple simultaneous touch points. The Samsung SUR40 can only run Windows 7, as the Surface SDKs are only fully supported on Windows 7 and not any newer Operating System. Window Presentation Foundation To initiate an application for any Microsoft Surface devices, especially for the PixelSense, the Microsoft Surface Game Studio 4.0 and Window Presentation Foundation (WPF) are required. Rowe (2012) shows a few points that can assist a developer to innovate and create a great application for the Samsung SUR40 Surface Table.7 Implement a darker background as it does better with quality during contact. Multiple screen interactions, in which, the users finger and objects, can be detected. Actions only must be interacted by the users fingers to avoid detection errors, and adding sound effects, acknowledging the users finger interaction, should be done. Ensuring the user immerses into an outstanding experience from the application. Since the PixelSense has 4 corners, it will be more convenient for users to be able to turn the orientation of the application, while offering an easy means of leaving the application. The points of interaction with the application, should be well sized and well-spaced, to prevent manipulation errors during input. Working with Touch Input To implement the 3D touch controls, a key prerequisite for the project is the availability of touch control capability. Using the System Information app, which could be launched from the Run dialog box, with the syntax msinfo32.exe. As seen from the image below, the Samsung SUR40 Surface Table, has 52 individual touch points. This confirms that the table supports the touch interaction and the touch framework is ready to use. Fig 1. The Run dialog, with the corresponding syntax, used to launch the system information window. Fig2. A System Properties window, showing the details on the touch capability. The initial edition of the 3D modelling software has sub-par touch navigation controls, but it makes up in the availability of buttons which are mapped to specific viewing points of the model. Having these buttons provides a way of navigating through, but lack the fluidity of the touch input system you would get from any other 3D modelling software. Fig 3. An image showing the initial edition of the source code, with buttons. Development Environment In order to be able to work on this project, a few software programs have to be installed. These software programs are specifically required to create an application for a Microsoft PixelSense device. These include: Windows 7 Microsoft Visual Studio 2015 Microsoft XNA Framework Redistributable 4.0 Refresh Microsoft XNA Game Studio Platform Tools Microsoft Surface 2.0 SDK Microsoft Surface 2.0 Runtime GitEXT Windows 7 Windows 7 is the latest operating system that the Surface SDK supports, hence, all the programming done, had to be on a PC running Windows 7. Running these programs on a Windows 10 PC, gives an unfixable error. A Windows 7 license had to be purchased. Microsoft DreamSpark provides a free license to the University of Surrey students. Using the downloaded ISO file, a USB boot key was made, using DiskPart, so as to dual boot Windows 7 on the laptop used. Using DiskPart, empties the flash drive of all its contents, its advisable to use an empty drive, or back up its contents. Fig 4. The error shown when the program is being opened on a Windows 10 PC. Fig 5. Image showing the free purchase of a Windows 7 Operating System, using DreamSpark. DiskPart is the Windows built in disk management program, using CMD to call it, the following syntaxes will create a custom USB key for any appropriately sized flash drive: List disk This lists out all the disk drives connected to the system, and their sizes, with disk numbers Disk ###, for easier disk reference. After finding your particular disk, use select disk x, x being the respective number of your disk. This basically tells the program you plan on working on this disk. Clean This clears your drive of previous configurations and empties it. Create partition primary This creates a primary partition on the cleaned drive. Select partition 1 This selects the recently created partition. Active this sets the selected partition as an active partition. Format fs=fat32 This syntax formats the flash drive to a requested file system. In this example, the file system being FAT32, the legacy file system recognizable by most BIOS (Basic Input Output System) firmware. Fig 5. The image shows the procedure for creating a USB Key, Disk 2. Visual Studio 2015 Microsoft Visual Studio 2015 is now a free software, but for the Enterprise version, a key is needed, but as a University of Surrey student, one is provided free of charge, under the DreamSpark account. Fig 6. Image shows free purchase of Visual Studio Enterprise, using DreamSpark. Microsoft XNA Framework and Microsoft Surface SDK A Microsoft Surface SDK installer was downloaded and installed, as an extension, for the Visual Studio 15 suite. This enables Visual Studio to compile on the Microsoft Surface XNA Game Studio framework. The installer sets up two important frameworks, which are the Microsoft Surface WPF and Microsoft Surface XNA Game Studio 4.0. These frameworks are applied to help developers with the creation of two-dimensional (2D) and three-dimensional (3D) applications respectively. A successful install will show something like this, when creating a new project in Visual Studio. Fig 7. The image shows a properly installed XNA Game Studio Framework. GitEXT GitEXT is an extension for windows, that helps manage a git repository. The programs source code had to be worked on alongside a few colleagues, as they had other objectives in terms of updating the 3D Modelling software. Using a git repository, helps with management of different modifications and changes between different editors of the same source code. Fig 8. The image shows an installed git extension for version management. Camera Movement Running a camera location around an object is a concept of projecting different views from different positions for audiences. It is an essential task for the developer to implement this concept in the application. In order to implement, a series of matrix calculations are required to move the camera from its current position to a desired place and display the object with high quality and performance. The current camera, as stated earlier, seen in Fig 3, has a fixed position, and does not move around the model, rather, there are fixed points in camera can be. These points are controlled by the arrow buttons. To fix this problem the touch framework has to be implemented. Touch Gesture The touch functionality of the program depended on raw input, and only moved the model round a fixed point. The method of implementation made navigation with the touch screen, somewhat ineffective. The XNA framework installed, comes with a touch input namespace namely Microsoft.Xna.Framework.Input.Touch. After extensive research on this library namespace, using this namespace made implementing a new gesture-based, touch framework for the code straightforward. The namespace provides support for gestures like tapping, double tapping, horizontal drag, and a few others. Development After researching various libraries and namespaces for a substantial understanding of the initial source code, coding began. During initial coding, it was discovered that the method of navigating the model, was rotating the camera round a fixed object, as it gives the same illusion as the model moving round its axes, as opposed to the manipulation of the model itself in front of an immovable camera. Using this logic, the touch code had to manipulate the cameras movement and not the movement of the model. While implementing the touch framework, a few redundancies were removed, such as the buttons used in moving the camera and a few others, to provide for a more immersive experience when using the 3D model. Fig 9. The image shows the 3D model with redundancies removed.
