In this study, the energy release rates in a centrally perforated star-shaped disk, which was made of a polymeric material, under internal pressure and thermal loads, were determined. The deformations of the disk were constrained by a circular steel ring enclosing the disk. Two constitutive models, namely, Hookean model and Ogden model, were used to model the constitutive behavior of the materi...

In the context of energy transition in Germany energy-optimized and resource-saving buildings building systems are being installed. To be able to do this, it is necessary obtain information from buildings, such as peak or base load heating/cooling electrical consumption. following publication a developed short-term analysis system based on modular non-invasive measurement will described. Additi...

A full three dimensional study of a tensile test on a sample made of polymerbonded propellant is presented. The analysis combines different tools, namely, X-ray microtomography of an in situ experiment, image acquisition and treatment, 3D volume correlation to measure three dimensional displacement fields. It allows for global and local strain analyses prior to and after the peak load. By study...

The presence of an electrical de-regulated market reinforces the need of forecast. Actions like network management, load dispatch and network reconfiguration under quality of service constraints, require reliable load forecasts. This paper establishes a methodological approach based on a Gaussian Process Model in order to choose an efficient endogenous information to be included in the input ve...

With regard to the importance of scientific decision-making in power plants prioritization to produce electrical energy (power) from renewable energies (purified), in this paper, research with specialists opinions with respond to questionnaires provided upon three efficient operational criterion in position of three presented power plant in country which used wind, solar water energies for prod...

Providing reliable electrical service has always been a key focus for distribution planners. Traditional forecasting and planning approaches have historically used average load growth over wide areas, basic analysis of weather impacts, and little, if any, attention to changing economic, resource deployment, or network topology changes. Exactly how resources and loads operate, interact, and prov...

1.1. Problem definition: Neuro-Fuzzy Approach in Electrical Load Forecasting Modeling and identification of electrical load processes are essential for the operation and also planning of a utility either for a company or for a country. Electrical load forecasting is needed because people intend to make important decision on generating power generators, load switching, purchasing strategy and al...
