Many systems used by the CERN accelerators and the technical infrastructure have to respect stringent requirements in terms of reliability, safety, availability and maintainability either for operation, security, or legal aspects such as the one required by French Regulatory Authority: the INB (Installations Nucléaires de Base ). The functional safety approach provides a structured method for a...

This paper discusses new infratechnologies in the deregulated power sector. Most measurement and standardization techniques can be viewed as infratechnology. Infratechnologies are technical tools, including the measurement of data, test methods, and practices and technique. Standardization requirements are related to the measurement requirement. Although the system operation and market transact...

Integration of Distributed Energy Sources (DESs) with traditional grid besides having many technical advantages, poses technical challenges to power engineers. Bidirectional power flow, dynamic fault currents are the few challenges. The relay settings need to be made adaptive to dynamic fault current levels of power system with DESs. Intelligent Electronic Devices (IEDs) can effectively be depl...

It is necessary to form an energy system in order to deliver the electrical power to a region that delivering energy to them from the national grid is not possible. At the moment, using the hybrid renewable energy systems (HRES) is the suggestion of more articles and scientific books because of environmental problems, nearing to the end of fossil fuels, and challenges including unpredictability...

background: today, issues such as water shortage, difficulties and costs related to supplying safe water, and anomalous concentrations of heavy metals in groundwater and surface water resources, doubled the necessity of access to technical methods on removing these pollutants from water resources. methods: in this lab study, cationic resin purolite s-930 (with co-polymer styrene di-vinyl benzen...

This paper describes and evaluates the Metalinguistic Operation Processor (MOP) system for automatic compilation of metalinguistic information from technical and scientific documents. This system is designed to extract non-standard terminological resources that we have called Metalinguistic Information Databases (or MIDs), in order to help update changing glossaries, knowledge bases and ontolog...

there is no doubt that just a healthy and balanced society could reach intellectual, technical, political and moral developments. there are some important and effective elements that wellbeing of society refers to them. no doubt that one of them is islamic hijab. accordingly, fiqh of islam insists on operation of hijab and we try to demonstrate that islamic hijab is not a personal or unimportan...
