After considering the spectral correlation of structure and statistics hyperspectral image, redundancy reduction is optimized using reversible transformation integer matrices in conjunction with N-band matrices. This paper proposes a new quantization algorithm, XCJRCT, that uses invertible matrix to remove redundancy, optimize bit allocation structure, lifting scheme discrete wavelet transform ...

This paper treats the file redundancy issue in distributed database systems asking what is the optimal number of file copies, given the ratio r of the frequencies of query and update requests. To draw a general conclusion applicable to a wide variety of practical distributed database systems, simplified network models are constructed , and optimal number of file copies, as well as their locatio...

As a consequence of current evolution trend of both software development paradigm and processor architecture, memory operations have become not only more frequent during program execution, but also more expensive in terms of hardware resource usage. A useful phenomenon which can be exploited to optimize memory operations is memory redundancy: loads and stores that have the same effects as previ...

Uncertainty is a practical issue in system design optimization because some characteristics of components, such as reliability and cost, cannot be determined precisely many situations. Considering the imprecise few works have focused on multi-objective for redundancy allocation due to challenges comparing multi intervals. To tackle issue, novel angle-based bi- objective algorithm proposed this ...
