The edges of shadows are blurred in Synthetic Aperture Radar (SAR) images due to the moving of the radar when data are collected. This phenomenon becomes obvious in High Resolution (HR) SAR images. In this work, an adaptive approach for shadow enhancements is proposed. The performance of the shadow enhancement has some relationship with the precision of the estimation of the height and this rule is...
In the retail market, the consumers' indecisiveness refers to the inability to make quick and assertive decisions when they choose among competing product options. Indeed, indecisiveness has been investigated in a number of fields, such as economics and psychology. However, these studies are usually based on the subjective customer survey data with some manually defined questions. Instead, in this...
In Java programs, it needs to use the information of the method type to resolve the virtual method dynamically, which restricts the performance greatly. Currently, the solution is mainly the technique of inline caching, which can be divided into two categories: monomorphic inline caching and polymorphic inline caching. Because of the simple implementation of monomorphic inline caching, it is more...
We investigate mainly the effect of sentiments on the volatility of Shanghai stock market returns. To be more objective, instead of using direct ones offered in the market, the indices of sentiments for both institutional and individual investors are constructed through a list of original indicators. From empirical results, we find that the stock market volatility is significantly influenced by irrational...
In atmospheric laser communication, a laser beam propagating through troposphere atmosphere suffers from irradiance scintillation caused by small but random atmospheric temperature fluctuations. However, the bit error rate (BER) due to such scintillation can be reduced by using a spatially partially coherent laser beam. On the basis of an earlier model of scintillation index for a partially coherent...
