This paper presents asymmetric-shaped tapers (or windows) for speaker recognition. Symmetric tapers (e.g., hamming), having the linear phase property and longer time delay, are widely used for short-time analysis of speech signals. Since human speech perception is relatively insensitive to short-time phase distortion, the linearity constraint on phase can be removed without any adverse effects....

This study recruited 14 young male participants to examine human 4-h maximum acceptable weight of lifting (MAWL) and maximum weight of lifting (MWL) for different modes of asymmetric lifting and containers. The results showed that asymmetric lifting with trunk rotation decreased MAWL and MWL by 9.1 and 17.3%, respectively, and asymmetric lifting with body turn decreased MAWL and MWL by 6.1%, wh...

We present a simple menu cost model which explains the finding that firms are more likely to adjust prices upward than downward. Asymmetric adjustment to shocks arises naturally, even without trend inflation, from the desire of firms to keep industry prices as high as is sustainable and the non-convexity due to menu costs. It implies that aggregate demand shocks have asymmetric effects — negati...

Different multicast routing protocols construct their distribution trees based on the information obtained from the unicast routing infrastructure. Nevertheless, the design of most of these protocols do not take into account that unicast routes may be asymmetric. Indeed, unicast routes in the Internet are very asymmetric. The effects on the quality of the multicast trees vary according to the r...
