In this paper, the client control system designed for infringement blocking system development. In order words, infected with harmful files on your computer by using a usercentered information systems development and security through the design of a control system using DNS control firewall client access to the site randomly for acts that can block the under solving techniques. Design of the cl...

empowering employees in specialized and general qualifications fields is required for urban management organization (tehran municipality). planning and establishment of comprehensive system of electronic learning is considered the main goal of human resource and educational managers. . this study tried to investigate the feasibility and execution of electronic learning courses for in-service st...

This dissertation studies the Multimedia Message Services that based on the digital television system, and it is called TVMMS for short. The author discusses the TVMMS architecture, and specifies the address number distributed for every entity and addressing scheme. The TVMMS can perform the following functions: point to point communication between STB, communication between STB (Set Top Box) a...

The paper deals with the public service system design, in which the generalized utility is to be maximized. The generalized utility defined for a public service system assumes that user’s utility comes generally from more than one located service center, on the contrary to the former formulations, where only one service center was taken into account as a source of individual user’s utility. Cla...

Improvements in networking technologies have provided users with useful information services. Such information services may bring convenience and efficiency, but might be accompanied by vulnerabilities to a variety of attacks. Therefore, a variety of research to enhance the security of the systems and get the services at the same time has been carried out. Especially, research on intrusion-tole...

This paper proposes a new type of service CAD system utilized in Service/Product Engineering (SPE), a much-needed and novel engineering discipline within the background of servicification. In this research a design-object model was defined, and a prototype named Service Explorer was implemented. The model represents critical concepts such as value, costs, functions either of products or of serv...

We consider the capacity portfolio investment problem with flexible machines facing multiple products and demand uncertainty. For the problem of maximizing the service level, we approximate the objective with the largest inscribing sphere and provide a linear program formulation. We show, under certain conditions, that the optimal flexibility configuration consists only of dedicated machines an...

The stochastic nature of emergency service requests and the unavailability of emergency vehicles when requested to serve demands are critical issues in constructing valid models representing real life emergency medical service (EMS) systems. We consider an EMS system design problem with stochastic demand and locate the emergency response facilities and vehicles in order to ensure target levels ...

Demand side management has gained increasing importance as the penetration of renewable energy grows. Based on a Markov jump process modelling of a group of thermostatic loads, this paper proposes a two level feedback system design between the independent system operator (ISO) and the regulation service provider such that two objectives are achieved: (1) the ISO can optimally dispatch regulatio...

This paper proposes the integrated design of an event stream service system architecture (ESSSA) which can be used as a gateway to capture and process enormous amounts of event streams continuously generated by radio frequency identification (RFID) or variable sensors over ubiquitous sensor network (USN) installed in a wide variety of locations, transfer the refined events to the various event-...
