Cholesky decomposition has wide applications in solving many engineering and scientific problems. Acceleration is an important issue in many of these problems. In this paper, a hardware-based LLT Cholesky decomposition featuring high throughput has been presented to solve wiener filtering based on the minimum square error criterion. To achieve the best efficiency, the hardware-based implementation...
To evaluate the sustainability of regional development, a comprehensive development index is put forward in this paper. Based on social-economy- environment theme indicator framework, the growth curve is taken to describe the development of each theme, then the comprehensive development index model is constituted. There are 2 parameters in growth curve and 2 parameters in index model. The PSO is applied...
In data grids, replication is a critical technology aiming at lowering the access delay as well as saving network bandwidth by duplicating original data in a distributed manner. For data-intensive applications with read/write files, replica consistency is an important issue. In this paper, we propose a novel replica consistency decision model with high adaptability and flexibility using the naive...
