DHHFLTS is a language terms based symmetry method uniform granularity. Firstly, we determine product up an team after formulating symmetrical...

Multiple signal classification (MUSIC) algorithm-based structural health monitoring technology is a promising method because of its directional scanning ability and easy arrangement the sensor array. However, in previous MUSIC-based impact location methods, narrowband signals at particular central frequency had to be extracted from wideband Lamb waves induced by each using wavelet transform. Additionally, specific center obtained after carefully analyzing signal, which time consuming. Aiming...

Abstract Marriage market imbalances are common in modern society for social and economic reasons, including the increased cost of marriage caused by high housing prices an imbalance number men women. We draw on family theory Gary Becker to study general equilibrium China. On one hand, we find that increasing price houses, important measure cost, has significantly reduced rate Another determining factor is sex ratio, with more than women, as a result China’s one-child policy. other higher GDP...

Product fault diagnosis has always been the focus of quality and reliability research. However, a failure–rate curve some products is symmetrical function, analysis result not true because failure period cannot be judged accurately.
