The traditional K-means algorithm is sensitive to the initial center, and equates the importance of dimension data for multidimensional data. So it is unable to block the effects of dimensional data dimension, nor can it well reflect the influence of each dimension of clustering. The semi-supervised clustering introduces a small amount of sample points, so that it can significantly reduce the number...
Fast Fourier Transform (FFT) is the basis of Digital Signal Processing (DSP). In this paper, a high performance FFT library using radix-2 decimation in frequency (DIF) algorithm is presented which is well suited for SIMD architecture. SIMD architecture microprocessors, such as Intel and AMD, allow parallel floating point operations on contiguous data in memory. A 128-point FFT based radix-2 DIF algorithm...
Based on the traditional TDOA location algorithm, two kinds of joint location algorithms of TDOA and TOA for TDMA system target sources are proposed. Due to the complementary positioning properties of TDOA and TOA methods in a 2-D plane, the problems of ambiguity and non-solution are avoided as well as the positioning accuracy in long-range situation is improved. At the end, simulation results illustrate...
In this paper, a new method based on equivalent network composed of zone-networks (zone-elements) is proposed and applied to reliability evaluation of distribution systems with the switch fault. In the method, the one-line diagram of the system is partitioned into zones with the auto (or non-auto) switch being the boundary; then two equivalent networks are respectively formed by two types of zone-elements...
