Drawing on a case study that adequately represents a medium-size component-based distributed architecture, the novel contribution of this paper is an economics-driven software engineering approach to the valuation of scalability in distributed architectures. Using real options analysis, we report on how ranges in which changes in scalability requirements can inform the selection of distributed ...

The inheritance of stress responsiveness (line effects and combining abilities) was phenotypically studied in progeny from diallel crosses of randombred (RB) quail and quail selected for exaggerated (high stress, HS) or reduced (low stress, LS) plasma corticosterone (CS) response to brief immobilization. The three genotypes were crossed in a 3 x 3 factorial arrangement of treatments that allowe...

The ecological cognition hypothesis poses that the brains and behaviours of individuals are largely shaped by the environments in which they live and the associated challenges they must overcome during their lives. Here we examine the effect of environmental complexity on relative brain size in 4 species of intertidal gobies from differing habitats. Two species were rock pool specialists that l...

Cognitive styles can be characterized as individual differences in the way people perceive, think, solve problems, learn, and relate to others. Field dependence/independence (FDI) is an important and widely studied dimension of cognitive styles. Although functional imaging studies have investigated the brain activation of FDI cognitive styles, the combined structural and functional correlates w...

The superior vena cava syndrome is due to the increased venous pressure in the upper torso, neck and head, caused by the obstruction of the superior vena cava. Both external and internal factors cause obstruction (95% are malign causes), and the most severe manifestation is represented by cerebral edema that can even lead to coma. The diagnostic algorithm for the superior vena cava syndrome is ...

On the basis of analyzing the principle of multicarrier DS-CDMA, we propose a novel multiband complex wavelet based multicarrier DS-CDMA system in this paper by using the optimized multiband complex wavelet as multicarrier basis function. The system bit error rate (BER) performance is investigated over Nakagamim fading channel. Without any cyclic prefix (CP), the proposed system can avoid the d...
