Cloud computing is considered to be a new service provider technology for users and businesses. However, the cloud environment is facing a number of challenges. Resource allocation in a way that is optimum for users and cloud providers is difficult because of lack of data sharing between them. On the other hand, job scheduling is a basic issue and at the same time a big challenge in reaching hi...

Abstract— The nature of active magnetic bearings has many advantages over the conventional bearing, as its operation is energy efficient and potentially leads to cleaner and noise-free environment. However, the successful operation of an active magnetic bearing system requires a complex real-time control system, because of its unstable characteristics, as well as its nature of being a multi-inp...

in this paper, based on the coupled-mode and carrier rate equations, a dynamic model and numerical analysis of a multi quantum well (mqw) chirped distributed feedback semiconductor optical amplifier (dfb-soa)  all-optical flip-flop is precisely derived. we have analyzed the effects of strains of qw and mqw and cross phase modulation (xpm) on the dynamic response, and rise and fall times of the ...

This paper proposed a multi-time scale robust energy management method for active distribution networks with the multiple terminal soft open point where network and microgrids belonged to different ownerships. In day-ahead Stackelberg game model, time-of-use price power exchange plan between were optimized under flow constraints balance economic benefits of all participants. Then reactive re-op...

today the usage of some compounds as indicator, can be checked changes of the food quality without opening the package. the most important indicators are indicates that show the level of product quality and freshness. freshness and temperature - time reagents reflect on extension of the product quality. indicators show the quality of the product, by physical and chemical changes which will be l...

A proactive librarian has a significant role to provide effective library service as well saving users' time. This study aimed explore the mechanism applied save time of user, and describe perspectives on services from Gyan Bikas Community (GBCL). research is based primary data collected users, who had visited library. The questionnaires field observations tools were used. GBCL provided differe...

The FingerPrint positioning method is known as a superior method in indoor positioning system that maintains previous signal strength patterns and compares with the measured new real-time signals on APs. In this paper, we analyze active signal phenomena using multi-rate Wi-Fi signals from reference AP which is accessed by multi-users. Some important factors which can effect to the accuracy by c...

This paper presents the space-filling curves and their applicability in scheduling, especially in transaction scheduling in Active Real-time Database Systems (ARTDBS). Active real-time databases have emerged as a research area in which concepts of active databases and real-time databases are combined into a real-time database with reactive behaviour. A novel space-filling curve based approach f...
