We propose a method for mutual fund performance measurement and best-practice benchmarking, which endogenously identifies a dominating benchmark portfolio for each evaluated mutual fund. Dominating benchmarks provide information about efficiency improvement potential as well as portfolio strategies for achieving them. Portfolio diversification possibilities are accounts for by using Data Envelo...

Based upon the raw S&P 500 portfolio performance in eight consecutive years, this paper gives an overview analysis of the application of influence diagram to portfolio management. Our findings provide a ground for the question: Is the structure information provide by the expert superior to the one generated by the data? In this study we use an artificial intelligence system called Influence Dia...

Software cost estimation is a crucial task in software project portfolio decisions like start scheduling, resource allocation, or bidding. A variety of estimation methods have been proposed to support estimators. Especially the analogy-based approach—based on a project’s similarities with past projects—has been reported as both efficient and relatively transparent. However, its performance was ...

Instruction prefetching can effectively reduce instruction cache misses, thus improving the performance. In this paper, we propose a prefetching scheme, which employs a branch predictor to run ahead of the execution unit and to prefetch potentially useful instructions. Branch prediction based (BP-based) prefetching has a separate small fetching unit, allowing it to compute and predict targets a...

with the advent of computer technology and educational software, hypermedia language learning materi-als made their way in foreign and second language classrooms. today the role of hypermedia in improv-ing communication skills is by no means deniable. this research aimed at investigating the effect of hy-permedia on the oral performance as well as the motivation of iranian efl learners. a prete...
