In the conventional rate distortion optimization (RDO) video coding, the measure of distortion is mainly from the perspective of signal processing, while dose not fully take into account the characteristics of visual perception. People have concerns about not only the information of independent pixels, but also the temporal and spatial correlations between them. For different video content, human...
This paper introduces Anarchic Society Optimization (ASO), which is inspired by a social grouping in which members behave anarchically to improve their situations. The basis of ASO is a group of individuals who are fickle, adventurous, dislike stability, and frequently behave irrationally, moving toward inferior positions they have visited during the exploration phase. The level of anarchic behavior...
Service Interface, which already exceeds the definition of service engagement, has been evolving to one of the key components to service industry in terms of enhancing competitive edge. Based on relevant national and foreign literature, this article focuses on five variables, which are human contact, human-machine Contact, online service (corporate website), service facilities and service processes,...
Social emotional optimization algorithm (SEOA) is a novel swarm intelligent population-based optimization algorithm by simulating the human social behaviors. However, it's diversity is decreased increased when solving high-dimensional multi-modal optimization problems. Therefore, in this paper, a new hybrid SEOA with Metropolis rule is introduced to enhance the exploration capability. To test the...
On the base of establishing rational talents structure evaluation index system the article defines indicator direction, index weight and has nondimension handling to establish comprehensive evaluation mathematics model. By defining two grades index and four structure index it has empirical study on talents structure evaluation of Hebei Province. The result shows that rational talents structure of...
The prediction model of indoor thermal comfort PMV index based on least squares support vector machine (LS-SVM) is established by using the nonlinear relationship between human thermal comfort and its influencing factors and the characteristic that particle swarm has of fast global optimization. Adopting the parameters of least squares support vector machine optimized by Particle Swarm algorithm,...
Structural optimization of Lennard-Jones (LJ) clusters is a classical NP problem. There are many local minima locating near the global minimum, and the local optima number is increased exponentially. Social cognitive optimization algorithm (SCOA) is a new swarm intelligent technique by simulating the human society. However, its local search capability is still weak. Therefore, in this paper, a novel...
The growing complexity of applications, huge data volume and the data structures to process massive data are becoming challenging issue. Query optimizer is a major component of a Database Management System (DBMS) that executes queries through different strategies and techniques efficiently. These techniques select the best optimal execution plan from the candidate plans according to the available...
In this paper we employ Structural Similarity Index (SSIM) metric in the rate-distortion optimizations of H.264 strictly I-frame encoder to choose the best prediction mode(s). The SSIM is designed to improve on traditional metrics like PSNR and MSE, which have been proved to be inconsistent with human eye perception. The required modifications are done on the JVT reference software JM92 program. The...
Human world is becoming more and more dependent on computers and information technology (IT). The autonomic capabilities in computers and IT have become the need of the day. These capabilities in software and systems increase performance, accuracy, availability and reliability with less or no human intervention (HI). Database has become the integral part of information system in most of the organizations...
The evaluation of corporation information systems is the key of the research on corporation information systems, which are complicated social technological systems, the estimate of them is a complicated social process. The multiple subjects, multiple stages and multiple levels of corporation information systems estimate decide the complexity in evaluating them. The complexity in evaluating corporation...
Corporation information systems estimate is the key as well as thorny point of the research on information systems. As corporation information systems are complicated social technological systems, the estimate of them is a complicated social process. The multiple subjects, multiple stages and multiple levels of corporation information systems estimate decide the complexity in evaluating them. The...
Functionality, complexity, heterogeneity and dynamism in computing environment are increasing day by day. This enhanced utility of computers has a profound impact on the systempsilas brittleness, manageability and security. Self-management is important in systems, networks, communication as well as in Database Management Systems (DBMSs). Autonomic computing reduces the problems and increases accuracy...
