Query optimizers use base-table statistics to derive statistics on the sub-plans that are enumerated during optimization. In practice, traditional optimizers rely on a number of s...
In Crypto’93, Stefan Brands [1] proposed a very efficient off-line electronic cash. Then, the subsequent researchers such as Ernest Foo [2,3], WK Yip [4] and Yiannis [5] develop...
—In this paper, we propose an efficient selective receiver for space-time block coding (STBC) scheme. In this proposed scheme, we divide the received signals into two groups. By ...
Abstract We present an efficient method for importance sampling the product of multiple functions. Our algorithm computes a quick approximation of the product on-the-fly, based on ...
Image synthesis often requires the Monte Carlo estimation of integrals. Based on a generalized concept of stratification we present an efficient sampling scheme that consistently ...
