A new idea to control of distributed parameter systems is to induct the boundary control idea into predictive control of distributed parameter systems. Because of complexity of distributed parameter systems, control system design is the difficulty of control theory. In this paper, discrete-time boundary, predictive control algorithm of first-order linear modulus-varying distributed parameter systems based on orthogonal wavelets transformation is proposed First-order linear modulus-varying distributed parameter systems in boundary control is approximated in Haar wavelets transformation. So the predictive control proposition of distributed parameter systems has been transformed into the predictive control issue of lumped parameter systems. the boundary Predictive controller is designed for the input sequence returning to the boundary predictive control rule of the original system. Simulation studies of the proposed algorithm, as well as the system robustness under uncertainty such as the parameters perturbations, and a disturb occurring to the system output are showed the results have verified the control effectiveness of the proposed algorithm.

Although e-Commerce systems have progressed over the past few years, they lack important aspects such as building long-term and profitable relationships with customers and facilitating an environment that encourages buyers to buy more. the actual execution of e-Commerce today is too different from its real-life counterpart, and for the most part it's a "Web page" with listing of items and prices. Providing an e-Commerce system that brings on-line shopping closer to the actual experience that people have in a real life environment would bring the system closer to the concept of 'e-communities'. In privacy-preserved communities, the system adheres to basic user protection and privacy principles along existing legal norms. this paper presents a Kerberos-based protocol for controlling and accessing privacy-preserved information from networked applications. Our approach is novel in that it incorporates a number of legal privacy requirements into the technical design of the system itself To our knowledge this work is the only e-Commerce e-community based solution built specifically to meet the requirements of privacy legislation, and designed to be controlled by a third commonly trusted application.

the paper deals with problems in distributed generation using synchronous machines equipped with squirrel cage for line starting. these machines need suitable control systems necessary to avoid damages during transients occurring when a network fault happens. the main characteristics of the behavior of controlled synchronous machines during synchronizing phenomena are analyzed and compared withthose of asynchronous machines. Analytical models of the two generation systems based on the two machines have been carried out and results of numerical simulation are reported.

In recent years, wireless sensor networks (WSNs) have been an interesting and important research area. Many routing protocols for WSNs have been designed to achieve high energy-efficiency, high reliability, low overhead, etc. However, few routing protocols for WSNs were designed to minimize the communication delay, which is one of the most important requirements for applications of WSNs, such as real-time surveillance systems. In this paper, a novel routing protocol for WSNs coined Delay-Minimum Energy Aware Routing Protocol (DERP) is proposed for guaranteeing real-time communication. Additionally, energy-efficiency that prolongs the network lifetime is fully considered Performance analyses and simulation results show that the DERP has much better performance than Directed Diffusion [2] and Rumor Routing [5] in terms of both communication delay and network lifetime.

Peer-to-Peer (P2P) technology benefits from a tractable and flexible job distribution scheme. However due to the dynamic nature of P2P, the optimal decision point of job scheduling is still unpredictable and some DLT-like heuristics are not sufficient to be a promising candidate for this role. As a reason of that, in this paper we have proposed the optimized time-constraint job distribution scheme in group based P2P networks. this scheme supports the hybrid type of jobs according to divisibility property. Also, it provides the methodology (3 phase-algorithms) which guarantees efficient job distribution under the condition of minimum completion time of executing jobs. through the simulation in the aspects of balancing and minimum completion time, we will discuss about its performance evaluation.

We consider the problem of assisting vulnerable people and their carers to reduce the occurrence, and concomitant consequences, of accidents in the home. A wireless sensor network employing multiple sensing and event detection modalities and distributed processing is proposed for smart home monitoring applications. distributed vision-based analysis is used to detect occupant's posture, and features from multiple cameras are merged through a collaborative reasoning function to determine significant events. the ambient assistance provided will assume minimal expectations on the technology people have to directly interact with. Vision-based technology is coupled with AI-based algorithms in such a way that occupants do not have to wear sensors, other than an unobtrusive identification badge, or learn and remember to use a specific device. In addition the system can assess situations, anticipate problems, produce alerts, advise carers and provide explanations.
