Sharpe-like ratios have been traditionally used to measure the performances of portfolio managers. However, they are known to suffer major drawbacks. Among them, two are intricate: (1) they are relative to a peer’s performance and (2) the best score is generally assumed to correspond to a “good” portfolio allocation, with no guarantee on the goodness of this allocation. Last but not least (3) t...

Background: auditory training improves the perception of complex acoustic signals as well as the perception of speech. Aim: to verify if auditory training, through the practice of music, has an influence on the ability to recognize speech in quiet and noisy situations. Method: participants of this study were 55 individuals, with no musical experience (non-musicians) and 45 professional musician...

With growth of PV market in tropical region, it is necessary to investigate the performance of different types of PV technology under the tropical weather conditions. Singapore Polytechnic was funded by Economic Development Board (EDB) to set up a solar PV test-bed for the research on performance of different types of PV modules in the country. The PV test-bed installed the nine different types...

This paper presents a cellular automata-based alighting and boarding micro-simulation model for passengers in Beijing metro stations. According to observations of passenger alighting and boarding behavior and an analysis of field data collected in three metro stations in Beijing, components of alighting and boarding time and the effects of different group sizes on the alighting and boarding per...

Multichannel synthetic aperture radar (SAR) in azimuth can resolve the contradiction between high resolution and wide swath faced with traditional SAR imaging. However, channel errors will degrade the performance of imaging. This paper compares the performances of four channel error estimation algorithms under different clutter distributions and SNR conditions. Further, explanations are given f...
