In this paper, based on Pareto dominant theory and gradient method, we proposed a kind of dominate gradient strategy. Dominate gradient is an intervention rule of local search for solving algorithm design in order to solve practical problems. Through the analysis and discussion for two dimensional functions in detail, we defined the situations of real superior, real inferior, false inferior and false...
A class of rate-compatible (RC) quasi-cycle low-density parity-check (QC-LDPC) codes that have linear encodable complexity and low error floor is presented. To ensure linear encoding complexity, a lower triangular (LT) form for the parity part of the mother parity-check matrix is designed. By the designed LT form, a recursive encoding strategy is proposed. This encoding strategy can achieve linear...
In this article, images obtained by multi-sensor use multi-resolution analysis of image fusion methods based on wavelet transform. Two source images obtained high frequency and low frequency components after wavelet transform. Using fusion rules with criteria based on local variance [7] to obtain low-frequency component. using an adaptive algorithm with local contrast of images to obtain the high-frequency...
The use of Prognostics and Health Management (PHM) technologies has recently received an increased amount of interest from many industries. For deployment of a PHM system successfully, A key step is prognosis certification. This calls for a set of performance metrics that not only evaluate key aspects of predicting into the future but also integrate notions from practical aspects such as reliability,...
Abstract-In power system restoration process, power transmission network reconstruction problem is studied. Using a complex network related theory, putting forward a comprehensive consideration node importance and transmission lines optimization network reconfiguration method. This method considers the influence of shunt capacitance on node importance, realizes the weighted power transmission network...
Peer-assisted content delivery systems can provide scalable download service for popular files. For mildly popular content, however, these systems are less helpful in offloading servers as the request rate for less popular files may not enable formation of self-sustaining torrents (where the entire content of the file is available among the peers themselves). As there typically is a long tail of mildly...
This paper is dedicated to the study of Symbolic Execution and improves the core algorithm of it using Heuristic learning, search and Function Abstraction to effectively address the path explosion problem, which will trigger the vulnerabilities that the traditional method can not find and improve the efficiency, precision and accuracy of software vulnerability discovery.
Combining fuzzy set with rough set, attribute reduction algorithm of continuous domain decision table is studied. First, continuous attribute value are transformed into fuzzy value with triangular membership function. And then, similarity degree of two fuzzy objects and similarity class of each fuzzy object are defined, in the meantime, characteristic vector of continuous attribute which is made up...
Load stability and the optimization problem is important for efficient parallel processing computer. A smart task allocation algorithm that intelligently select the node status and startup strategies, the total load assigned to the appropriate node to enable communication and processing minimal overhead, load balancing, parallel processing system so that the overall performance of the best, lowest...
In this paper, we propose a new algorithm for dynamic voltage scaling (DVS) based on feedback control mechanism. Besides handling a periodic tasks, our algorithm significantly reduces the energy consumption of periodic tasks and consequently the energy consumption of the whole task set. The results show that, comparing to on-line dynamic voltage scaling (the best algorithm to our knowledge), our approach...
