The circuit board is inserted in a card carrier which is cooled by flowing liquid water at temperature Tc. The circuit devices are mounted in chip sockets which make electrical contact through their base. The thermal bond between the chip sockets and the circuit board is such that the local socket temperature may be considered equal to the local board temperature. The power dissipation of each device, as well as other pertinent data, are summarized in Table 1. You are assigned to determine the optimal locations and orientations of the two chips on the circuit board to minimize the maximum chip temperature during operation. According to your design, what is the steady state temperature distribution in the board? The effect of losing air cooling is also to be analyzed in terms of the time history of the maximum chip temperature and the new equilibrium temperature distribution. All modes of heat transfer must be considered, and any assumptions must be justified. If a computer program is necessary (including ANSYS), the accuracy of the program, as well as the results, need to be checked and verified. For example, it may be possible to check the program by comparing numerical results using different resolutions to show grid convergence, and against analytical results, obtained for some limiting case (e. Your report, using the format given below, will be graded on the basis of the physical understanding exhibited, the clarity of writing and reasoning presented, and the quality of the design characteristics. The written report and a computer program or simulation, if necessary, are to be the original work of each individual student. This project is due on the last day of classes, Wednesday, December 2, 2. Schematic of circuit board cooling design problem.

Orders for single pizzas (no other orders are accepted) arrive with an inter- arrival time that is exponentially distributed with a mean of 3. The outlet has one oven with a capacity of five pizzas.

Check on You. Tube, they have many videos that can help! No expert has answered this question yet. It could be caused by global warming as some political figures would have us believe. But as I prepared this exercise for you, we have seen incredible violence in Paris, Brussels, Bamako, and threats of violence world- wide. The strangest alignment of nations – some of which have spent much of their history as rivals. What is the current focus of attention? Could it be ISIS, ISSL, the global caliphate? It may be involved with the perceived weakening status of the United States in political and economic realms, especially within the context of income redistribution, economic competitiveness, and the (un)affiordable health care. Perhaps it comes from the context of institutional changes, such as whether same- sex marriage is a natural right? Does it have a basis in the unrest surfacing in various communities – such as universities and colleges? Until recently, people looked to Europe and North America for solutions, and direction. Now it would appear that the foci are shifting away from the West, to other regions. Does this mean that Western Civilization is dying, dead, morphing, or alive and resilient? How to attempt this assisrment: Find and enumerate 2. Research, document facts, historic incidents, realities that you choose by making a value judgment of your own on the current condition of Western Civilization. It’s possible that you could have a combination of factors representing dying, thriving, or morphing! Do you need to deline the term western civilization? Do you need to space out your examples? Most likely – you will find them in all areas: philosophy, science, morality, social values and behavior, historical record, events, and issues. Notably you should also be able to place these events in time – not all need be recent nor should they all resemble a chronic crank’s complaint Iist about how things aren’t the way either a liberal or conservative ideally sees things! Definitely look within and outside our national borders for your examples. Changes over time could be a factor in your evahntion! Should you necessflrily have to restrict your opinion to philosophical, political, or religious factors? What I am looking for is an academic examination of this topic. Should you quote public personalities, pundits? This assignment’s origin is based on Patrick Buchanan’s book The Death of the West. No expert has answered this question yet.
