In the new generation of mobile communication systems, high data transmission rate and low bit error probability have been common requirements. However the issue of signal fading in a multi-path environment still stands as an major problem. Using antenna diversity techniques can overcome the problem. The main purpose of this thesis work is to implement receiver antenna diversity in a mobile ter...

BACKGROUND Social scientists have suggested that cultural diversity in a nation leads to societal instability. However, societal instability may be affected not only by within-nation or alpha diversity, but also diversity between a nation and its neighbours or beta diversity. It is also necessary to distinguish different domains of diversity, namely linguistic, ethnic and religious, and to dist...

Research on the relationship between work group diversity and performance has yielded inconsistent results. To address this problem, the authors propose the categorization-elaboration model (CEM), which reconceptualizes and integrates information/decision making and social categorization perspectives on work-group diversity and performance. The CEM incorporates mediator and moderator variables ...

We investigate software process diversity, defined as the project condition arising out of the simultaneous use of multiple software development process frameworks within a single project. We analyze the antecedents and consequences of software process diversity and examine the relationship among software process diversity, organizational process compliance, and software project performance. Ou...

The relationship between ensemble classifier performance and the diversity of the predictions made by ensemble base classifiers is explored in the context of heterogeneous ensemble classifiers. Specifically, numerical studies indicate that heterogeneous ensembles can be generated from base classifiers of homogeneous ensemble classifiers that are both significantly more accurate and diverse than...

T paper examines the effect of recommender systems on the diversity of sales. Two anecdotal views exist about such effects. Some believe recommenders help consumers discover new products and thus increase sales diversity. Others believe recommenders only reinforce the popularity of already-popular products. This paper seeks to reconcile these seemingly incompatible views. We explore the questio...

One way forward is through the use of diversity. The best-known applications of diversity in computing date back a couple of decades and involve design diversity, e.g. n-version programming. This kind of diversity, in the pursuit of fault tolerance, has had a checkered history. On the one hand, several famous experiments have shown that the benefits fall far short of what might be expected if t...

THE PLAINS The Plains region, an area delineated by the Rocky Mountains on the west; the Canadian provinces of Alberta, Saskatchewan, and Manitoba on the north; the Mississippi River on the east; and the Gulf of Mexico on the south, is home to philosophies, traditions, and ways of life that are some of the most varied and complex in the United States. The Great Plains measure 1,125,000 square m...

The article presents a normative principle of constitutional justice that acknowledges ethnocultural and ethnonational diversity by addressing the injustice of political alienation. It is suggested that this principle could be the subject of a methodological overlapping consensus among several comprehensive normative-theoretical frameworks that are influential in current debates. The main impli...
