Von Neumann architecture, or the Von Neumann model, stems from a 1945 computer architecture description by the physicist, mathematician, and polymath John von Neumann and others. This describes a design architecture for an electronic digital computer with a control unit containing an instruction register and program counter , external mass storage, subdivisions of a processing unit consisting of arithmetic logic unit and processor registers, a memory to store both data and commands, also an input and output mechanisms. The meaning of the term has grown to mean a stored-program computer in which a command fetch and a data operation cannot occur at the same time because they share a common bus. This is commonly referred to as the Von†¦show more content†¦Ã¢â‚¬ ¢ Add the span or extent of the instruction to the program counter. †¢ Interpret the instruction using the control unit. Meanwhile, The control unit commands the rest of the computer to perform some type of operation. The instruction may change the address in the program counter, thus permitting repetitive operations. The instruction may also change the program counter . this is done only if some arithmetic condition is true, thus giving the effect of a decision, which can be calculated to any degree of complexity by the preceding arithmetic and logic. †¢ Once all of this is done, it is programed to go back to step 1. The design of The Von Neumann architecture is a little more straightforward than the more modern Harvard architecture. It too is a stored-program system; nevertheless, it has one dedicated set of address and data buses for reading data from and imprinting data to memory, and an additional set of address and data buses for obtaining instructions. Von Neumann devoted most of his Preliminary Discussion to the design of the arithmetic unit. The details of this are the least interesting part of the paper from the standpoint of the organization of his computer, and its influence on future developments. The capabilities of the arithmetic unit were limited to the performance of some arbitrary subset of the possible arithmetic operations. He observes that theShow MoreRelatedOne Significant Change That Has Occurred in the World Between 1900 and 2005.

Starting blocks has came a long way from being a single holes dug in the ground to the high tech, lightweight, but yet expensive running aid their now. We will write a custom essay sample on Triple Jump Phase or any similar topic only for you Order Now To properly observe and describe the breakdown of the hop, skip, and jump phases, while determining the muscles that cause these movements. The triple jump, referred to as the hop, skip and jump, is a track and field event similar to the long jump. The only difference between the two is that the hop, skip, and jump involve a hop and a step, whereas the long jump involves just a jump. In the first phase of the triple jump, the competitor builds momentum by sprinting down the runway, planting their lead foot at the marked board, and â€Å"hops† into the air, cycling one leg around into phase two. After completing the cycle, the lead foot strikes the ground again initiating the â€Å"skip†, where the opposite leg is brought up and the body goes into the bounding position. Finally as the body is coming out of the bounding position, the opposite leg hits the ground in order to propel or â€Å"jump† the body forwards, aiming for distance rather than height, into the pit. [pic] The phases In the triple jump, there are three joints that aid in movement of the hip, the knee, and the ankle. Together the three joints allow optimum distance and proper stability for the jumper. The hip, which holds the femur and pelvis, allows the jumper to extend as his foot strikes the board. While keeping the knee in flexion, he pushes off into the cycling pattern. In the skip phase, the hip will remain in a flexed position as the trail leg goes into extension. When in the jump phase, the hip allows the leg to go from an extended position, to a partial flexed position. The knee, which hold the fibula, tibia, femur, and patella, just like the hip is a very important part of the triple jump process. In the initial â€Å"hop† phase, the knee extends, but quickly switches to flexion throughout the cycling pattern. During the â€Å"skip† phase the knee will remain in flexion, while extending the opposite leg. Following the second phase, the lead leg switches to the trail leg, which remains in flexion for the final â€Å"jump†. Finally, the ankle is made up of three separate joints: the talocrucal joint, inferior tibiofibular joint, and subtalar joint. These joints, just like in the kinetic chain, are where the power originates from. In the â€Å"hop† phase, the ankle of the lead leg will remain dorsi flexed, and the trail leg will be slightly plantar flexed, but will quickly draw up into the dorsiflexion. As the jumper enters into the â€Å"skip† phase the ankle will remain dorsiflex, while the trail leg switches to the front. This will allow the trail leg to go dorsiflex, and the lead leg to deliver a powerful push-off into plantarflexion. [pic] The muscles and their functions in the Hop, Skip, and Jump phase. The muscles involved in the triple jump are the quads: rectus fermoris (allow hip concentric flexion and knee eccentric extension), vastus lateralis, medialis, and intermedius (helps the knee eccentric extend); the hamstring muscles: semimembranosus, semitendious, and biceps femoris (allows the jumper to extend the hip and normally pair with the help of the eccentric gluteus maximus); and finally, the lower leg muscles: concentric tibialis anterior, the concentric extensor digitorum longus (which provide the ankle with the ability to perform dorsiflexion), the peroneus longus, soleus, and gastrocnemius (which allow eccentric planterflexion for that last jump push-off). The main stabilizer, the gluteus medius, acts as a front plane stabilizer and restricts the leg from turning in vargus or valgum, allowing the leg to plant. Conclusion An important factor in determining the power and momentum developed in the sprint start is the angle of the front leg in the set position. Most literature accepts that an angle close to 90 degrees is the ideal angle in this position. It allows the knee extensors to work best at the correct time for maximum power and momentum to be developed. An angle in excess of 90 degrees may allow a faster leg speed out of the blocks but will not develop the same power and momentum. Borzov (1980) in his investigations into an optimal starting position varies a little, with a suggested ideal front leg angle of 100 degrees. Opinions on rear leg angle vary between 110 degrees and 135 degrees. Tellez Doolittle (1984) suggest an optimal angle of about 135 degrees for the rear leg because it allows the lever to move more quickly and allows greater impulse from a static position. They also suggest that an early body velocity provided by the rear leg drive past the front leg is a better mechanical position to accelerate through a more prolonged application of force.

Global Issues in Health Care Policies and Management

Question: Are developing countries following the track of developed countries? Answer: Today most of the countries are designated as developing country", therefore, it is obvious that they are trying to follow the path of developed countries. However, the real question is what is what is the current score of the developing countries while comparing with developed countries? Three random countries can be selected and compared to find out the answer. For instance, Australia is chosen as the developed country, and Nigeria and India are selected as developing countries. Australia has the 12th largest economy in the world. According to the survey of 2014, Australia had fifth-highest per capita income. Australia is the sixth largest country with a total GDP of $1.241 trillion (nominal) (Raphael, 2011). On the other hand, India is a developing country of South Asia. India is the seventh largest country, just behind the Australia with a population of 1.2 billion people. This country is considered as the most populous democracy in the world. India is a secular country, and it is found that four major religious originated here, such as Jainism, Sikhism, Buddhism, and Hinduism (Saha, 2013). On the other hand, other religions like Zoroastrianism, Christianity, Judaism and Islam arrived and dissolved with the "Indian culture". The current GDP of India is 2.182 trillion (nominal); however, the per capita income is too low (Dave). Another developing country is Nigeria, situated in the West Africa, which comprises 36 states. Like India Nigeria is also known as secular democratic country. Nigeria has a population of 182 million inhabitants and popularly known as "Giant of Africa." Besides, there are 500 ethnic groups in the Nigeria, which include three major ethnic groups such as Yoruba, Igbo, and Hausa. It is found that more than 500 different languages are spoken in Nigeria, which is just the double of languages spoken in entire Australia (250). However, India beat them all, as the Indian census (1961) recognized 1,652 languages spoken in India and 22 of them are official languages. It is found that the differences of language and existence of different cultures are the main hindrance of the development of India and Nigeria is no exception. Though the official language of Nigeria is English, the country is distinctly divided between Christian and Muslims. From the research, it is found that developing country like India and Nigeria has a massive wealth gap, which means that the rich people are becoming richer and the poor people becoming poorer. In Nigeria, it is observed that most of the rich people spend their money to buy expensive jewelry and cars. The picture is almost same in India. In India, most of the rich people like to show off their money by building expensive houses or buying heavy muscle cars. On the other hand, it can be found that in Australia people try to lead almost a moderate life except of course the celebrities (Connell, 2012). The per capita income of Australia is more than the per capita income of India or Nigeria. However, the wealth gap is shorter in Australia than these developing countries. From a survey, it is found that average Australian people spend $223 on their housing and $20 for the health practitioners. Most of the common people in Australia have full life coverage. On the other hand, most of the common people in India do not posses any life coverage. When Nigeria is focused, it is observed that the condition of the common people in Nigeria as same as India. A huge number of common people of Nigeria are considered as below poverty line and do not posses any life coverage. According to the "Africa wealth report 2015", there are 15,400 dollar millionaires live in Nigeria, who posses, at least, one million dollars in their assets (Oluwatobi Ogunrinola, 2011). Now, here is a controversial part, most of the money possess by the rich people in Nigeria are not white or more precisely not legitimately earned. In the case of India, the situation is also very same as Nigeria. Most of the wealthy people in India do not possess white money, and they have their ways to convert black money into white money. Now the point is why a country put so much weight on their black money. This is because the amount of black money controls the inflation of the economic market. In Australia, there is less amount of inflation as the amount of black money in this country is not heavy. When the health related matters are compared among three of these chosen countries, it is observed that most of the common people in the developing countries still do not posses full life coverage. Although hospitals in the primary health centers in India offers free medical services to the poor people, in most of the cases these facilities are not sufficient. Still in the major rural part of India, people are deprived of free medicines and health care facilities provided by the governments. It is found that the availability of the health care facilities also varies in India depending upon different cultures. Most of the underprivileged women in the rural part of the India still give birth of the child in their homes and are deprived of the primary facilities of the health care system. In Nigeria, the country is completely divided into two parts depending on the religion Christian and Muslim (Perkins et al., 2012). The health care facilities greatly vary in these two parts of this co untry. However, it is a controversial topic, and the government is trying their best to resolve their problems. On the other hand, there are actually no health care-related problems or issues were found in the research. The nurses and the doctors are very cooperative and helpful. From a survey, it is found that the doctors in Australia charge lesser than the doctors in India are (Dyster, Meredith, 2012). Besides, the infrastructure of the health care system is far better in Australia than in the India and Nigeria. However, there is another factor that needs to be focused on; this is the political factor. In Australia, the political chaos is lesser than other developing as well as many developed countries in the world (Rosenberg et al., 2011). Especially in India, the political turbulence is highly noticeable. There are many political parties in India, and they are in a constant fight to hold on to their position, which in turn form a chaotic situation, and that is not helpful for the growth of the country (Bhupal, 2013). Besides, terrorism in India is well versed. There are more than six terrorist attacks in India in last one year, which is certainly not helpful in the development of a country, and these terrorist attacks can be considered as the failure of the Indian government. In Nigeria, the situation is almost same. In this country, the political turbulence is based on the differentiation of the cultures (Christian and Muslims). Most of the common people in this country are fighting with each other based on their religion (Bakare Olubokun, 2011). The government of Nigeria is trying their best to dissolve this problem and reach towards a permanent solution. However, they are not even closer to their success. So far, the developing countries are trying their best to hold on to their progress. It is a fact there are several pitfalls in this long journey, but it can be assumed that they will reach their target eventually. On the other hand, the developed countries like Australia just do not claim themselves as developed, but they are trying to help the developing countries in their progress by providing them resources.
