Residual Heat

The rotary inertia of the reactor’s primary pump is an important factor related to the reactor’s safety under some accidental conditions. If the rotary inertia of the primary pump is big, that the pump’s inertia time will be long and the coolant mass flow rate will decrease slowly. So it is helpful to remove the residual heat and enhance the safety of the reactor. On the other hand, a bigger rotary inertia increases the cost, and causes some other inconvenience. In this paper, our research object is China Advanced Research Reactor (CARR) which is under construction. Systemic mathematical and physical models were set up and a program was developed using FORTRAN language with GEAR numerical method to analyze the transient of CARR. The primary thermal-hydraulic parameters of the reactor core were obtained in case of loss of power accident under different rotary inertia of the pump. These parameters include the temperature of the coolant the clad and the fuel, the maximal quality of the reactor core and MDNBR, etc. On the basis of the calculate result, it can be found that when the rotary inertia of the pump is larger than 150 Kg·m2, all of the thermal parameters in loss of power accident meet the safety requirement. And if the rotary inertia of the pump is 450 Kg·m2 which is the design value of CARR, the delay shutdown time in loss of power accident must not exceed 20 seconds.

<p align="center"><strong><em>Abstract</em></strong></p><p><em>           There is a threefold increase in video traffic over internet. Due to this video compression has become important. Compression of video signals is quiet an interesting task but comes at the cost of video quality. After compression, two methods are scientifically applied to evaluate the quality of video; Subjective and objective analysis. In subjective approach the compressed video is shown to a group of viewers and their feedback is recorded Objective approach aims to set up a mathematical model which can approximate the results of subjective analysis. One such approach is based on the measurement of PSNR. When a signal is applied to the encoder for compression, too much of compression results in a signal with a smaller size but at the same time quality of the signal degrades. In this paper we will compare the quality of compressed video signals produced by H.264, Mpeg2 and Mpeg4 encoder based on the values of MSE and PSNR. Lower the value of MSE, higher will be the PSNR. Comparative plots of MSE, PSNR, SSIM and images for subjective analysis have been added at the end of this paper. </em></p>

Reducing Stress

In today’s competitive industrial environment, the quality of a product is no longer the major factor which influences purchase by a customer, it is simply a prerequisite for competing in the market. To compete and survive, the necessity is to provide the product at an affordable price, a target that can only be attained through actions such as improving the efficiency of manufacturing operations. In sheet metal industries, the cost of tooling contributes a considerable part to the overall manufacturing cost of a component. It is imperative to keep this cost down by ensuring the tool operates uninterrupted for long periods of time, achievable in one way by reducing the stress on the tool during punching by optimizing the clearance between the die and the punch. This paper deals with this problem using finite element techniques. Having created models of various punch configurations, one is able to analyze the effect of variations in tool geometry on punching force and tool deformation, a parameter highly relevant in assessing performance in terms of the accuracy of machined components. Computed results using FE models are compared against results obtained through experimentation. Due to the nature of the punching process being inherently noisy, consideration was given to noise levels, how they are affected by changes in tool geometry, and the subsequent effect on the workforce considering the fact that reducing stress on the operator could only improve quality and productivity. Finally, some suggestions are given as to how the efficiency of a punching tool and quality of the punched product can be improved.

This paper explores the hypothesis that technology can be used to improve product quality, speed up delivery and reduced cost. For companies improving the quality of their products, reducing the cost and improving the speed of delivery makes them favorable to the client who feels like all their needs have been met. The research occurs between the months of January 2018 to April 2018 which is about four months. The research experiment design uses the pretest-posttest experimental design set up between two companies both using the traditional method of manufacturing with no technology. In one company technology is introduced while in the other company the process remains the same traditional method of production. Both companies analyze the results at the end of a four-month period before a conclusion is drawn from both the pretest and the final test. The experiment results show that technology improves quality of the product, improves the speed of delivery while at the same time reduce cost benefiting both the producer and the client. Technology should, therefore, be implemented in companies to give them an edge over the competition. With technology in companies, the United States can reclaim production from overseas companies that have taken over by providing cheap labor. Better satisfied customers mean more production which in turn means more jobs for the people in the United States.
