Pervasive social networking (PSN) is a fundamental infrastructure in social networking that has played an important role in not only the Internet but also mobile domains. A practical and accurate evaluation system is required to ensure the further development of PSN. Secure and efficient communication is also an essential issue in PSN to increase its adoption in daily life. In this paper, we discuss...
This paper aims to study the measurement and modeling methods for delays in wide-area closed-loop control systems (WACS). The delays are classified into communication delays and operational delays based on the information flow of WACS. For communication delays, an affine evaluation model is proposed based on previous studies, and this model is verified by the measured communication delays of the Guizhou...
Recently, Yang et al. Proposed a remote user authentication scheme using smart card. Through careful cryptanalysis, we find that Yang et al.'s scheme is not repairable, and cannot achieve mutual authentication and session key agreement. To overcome these security flaws, we propose a new remote user authentication scheme with smart card. In the proposed scheme, the user can choose his/her password...
Remote user authentication is an important and efficient method to ensure security for many network-based application systems. So far, several dynamic identity based authentication schemes have been proposed to protect the user's anonymity. Recently, Sood pointed out the security weaknesses of a dynamic identity based authentication scheme, which was proposed by Wang et al. presented an improved scheme...
Recently, An pointed out the weaknesses of Das's three-factor remote user authentication scheme, and proposed an improved biometric based three-factor remote user authentication scheme. An's scheme improves the security problems of previous schemes while keeping the efficiency. However, after detailed analysis, we find that An's scheme exists some weaknesses such as vulnerable to denial-of-service...
IDC(Internet Data Center), the large scale Server and Data Memory and so on are connected to three-phase supply power system via single phase. Because of differece of the visit capacity to a same server or data memory, the unbalance of the three-phase supply power system is much larger. It wastes much more energy. Try to control the user load of every phase to realise the balance of three-phase power...
This paper presents a modified R-learning according to the traditional average reward reinforcement learning algorithm. Reinforcement learning problems constitute an important class of learning and control problems faced by artificial intelligence systems. The general framework of reinforcement learning can be divided into two forms, discounted reward reinforcement learning and average reward reinforcement...
Collaborative decision-making optimization of intelligent information service alliances is the important support in modern economic transformation. At first, here the logos model and strategy of the collaborative decision-making optimization for a chance in the harmony game are applied to discuss the theory and method of intelligent information Service alliances and to explain the new characters of...
