Design paradigm exactly addresses the higher-level design issues where the implementation field (mechanical, electrical etc.) of the product is left for later stages. Once the general design problem is understood, better products will be emerging; especially products requiring a cooperation of various engineering-field components are a bigger concern. The idea is that design is a phenomenon, cu...

Abstract: properties of AA6082 aluminum alloy. Considering that aging phenomenon affects the distribution of alloying elementin matrix, and the fact that different distribution of alloying elements has different impediments to dislocationmovement, a material model based on microstructure, has been developed in this research. A relative volume fractionor mean radius of precipitations is introduc...

Organizational risk is often defined as a change in the flow of profit, or as a sys-tematic or non-systematic changes in the stock return flow. The risk taking of management is conceptualized as the actual investment decisions that are indictors due to uncertainty results. The purpose of this study is to investigate the effect of financial characteristics on future corporate risk taking behavio...

The paper suggests an approach for optimizing a material ow system consisting of two work-stations and an intermediate bu er. The material ow system may be a production system, a distribution system or a pollutant-deposit/removal system. The important characteristics are that one of the work-stations is unreliable (random breakdown and repair times), and that the performance function is formula...

1. Introduction The automotive industry is one of the most automated manufacturing industries worldwide nevertheless there is still a lot of potential for further improvements. On the given example of an existing production plant at DaimlerChrysler AG a new holonic concept has been developed by HMS partners breaking up rigid transfer line structures and introducing new concepts of flexible reso...

Globalization is a worldwide phenomenon. The concept globalization is a very recent term only establishing its current meaning in the 1970s, which emerged from the intersection of four inter related sets of communities of practice, academics, journalists, publishers. This paper models the channels through which globalization affects financial sector development in Nigeria. To this end this stud...

Abrasive flow machining (AFM) is a process for the production of excellent surface qualities of inner profiles that are difficult to access and outside edges, as well as for deburring and edge rounding. The grinding medium used in AFM consists of a polymer fluid, the so-called base, in which the abrasive grains are bound. The grinding medium is pressed along the contours at a defined pressure a...

Composite structures are already in use in secondary parts of the Douglas MD-11 and are planned to be used in the new MD-12X. Plans also exist for their use in primary and secondary structures on the Boeing 777. Douglas’ proposed MD-XX may also incorporate composite materials into primary structures such as the wings and tail. Use of composites in these structures offers weight savings, corrosi...

A crucial requirement to promote and sustain energy conservation measures in buildings is the ability to perform careful and reliable appraisals of exactly how much energy has been saved. This paper briefly describes the general issues involved and then focuses on commercial buildings where retrofits are made in order to reduce energy consumption in hot water, chilled water and in electricity c...

This research examined the time series characteristics of stock price indices for Hong Kong, Tokyo, New York (NYSE) and London (FTSE) equity markets or stock exchanges during the period of 1991 to 2012. Specifically, we calculate the rate of return and the volatility of return for all the markets and estimate the serial correlation and co-movement of the four markets. We find that the average r...
