We examine the impact of excluding sin stocks on expected portfolio risk and return. Exclusions involve relative to market peers. show how this tracking error can be translated into an equivalent loss in return, which is negligible at low levels, but not higher levels. However, even modest ex ante levels may lead sizable compounded underperformance post. Taking asset pricing perspective we find...

Cost management is an important part of enterprise financial work. Active cost can effectively reduce costs and lay the foundation for long-term development enterprises. When analyzing enterprises, this paper understands current situation problems existing in by consulting literature reports, finally chooses to combine two from perspective performance incentive, combined with management, hoping...

The objective of unicast routing is to find a path from a source to a destination. Conventional routing has been used mainly to provide connectivity. It lacks the ability to provide any kind of service guarantees and smart usage of network resources. Improving performance is possible by being aware of both traffic characteristics and current available resources. This paper surveys a range of ro...

as one way to approach industrial symbiosis, environmental infrastructure sharing is principally concerned with providing an integrated environmental utility system for clustered firms. it is based on the assumption that environmental infrastructure sharing can improve the regional competitive advantage by reducing overall cost and improving environmental performance. in order to verify the ass...

A dual structural fused system consists of replaceable ductile elements (fuses) that sustain major seismic damage and leave the primary structure (PS) virtually undamaged. The seismic performance of a fused structural system is determined by the combined behavior of the individual PS and fuse components. In order to design a feasible and economic structural fuse concept, we need a procedure to ...

performance optimization of a single-effect lithium bromide water absorption refrigerationsystem is the subject of this paper. first, the thermodynamic model of the system wasderived based on thefirst and second law analysis of an absorption refrigeration cycle with libr-water as the working fluid pair.then, the effects of different design parameters such as the generator inlet hot water temper...

Emerging trends in commodity network technology coupled with key insights from academic research in active memory systems are leading toward the realization of hardware DSM on commodity clusters. We call the result of this convergence active memory clusters. After discussing the current state of the art in hardware DSM, clusters, and software DSM architectures, we highlight the key di erences b...
