The market for power semiconductor modules is spreading not only to general-purpose inverters, servo motor drives, NC machine tools and elevators but also to new applications through the realization of electric vehicles and renewable energy systems. Fuji Electric has developed various power modules in response to market needs, and as the market expands in the future, the required performance fo...
Due to imprecision and uncertainties in predicting real world problems, artificial neural network (ANN) techniques have become increasingly useful for modeling and optimization. This paper presents an artificial neural network approach for forecasting electric energy consumption. For effective planning and operation of power systems, optimal forecasting tools are needed for energy operators to ...
abstract: country’s fiber optic network, as one of the most important communication infrastructures, is of high importance; therefore, ensuring security of the network and its data is essential. no remarkable research has been done on assessing security of the country’s fiber optic network. besides, according to an official statistics released by ertebatat zirsakht company, unwanted disconnec...
In this research, hydrodynamic behavior of a leaky dielectric droplet under an electric field is simulated. The level set method is used for interface tracking and the ghost fluid method is used for modeling discontinuous quantities at interface. Using Taylor’s leaky dielectric model, electric field and electric force at the interface is calculated. Simulation results show the droplet deformati...
In contrast to conventional internal combustion engine driven vehicles, the number of motors in fully electric cars is not fixed. A variety of architectural solutions, including from one to four individually controlled electric drive units, is possible and opens up new avenues in the design of vehicle characteristics. In particular, individual control of multiple electric powertrains promises t...
Transformation of the monopolistic electric industry into a competitive and free market system is underscored by the wide price variation of electricity. To address price variation, the Federal Energy Regulatory Commission has proposed the development of fair competition in the wholesale power market as a first step toward full deregulation of the industry. This paper will discuss the steps tha...
Increasing sensitivity of modern evaluation tools allows for the study of weaker electric stimulation effects on neural populations. In the current study we examined the effects of sham continuous theta burst (cTBS) transcranial magnetic stimulation to the left dorsolateral prefrontal cortex (DLPFC) upon somatosensory evoked potentials (SEP) and frontal-parietal phase coupling of alpha and beta...
Depth map images are characterized by large homogeneous areas and strong edges. It has been observed that efficient compression of the depth map is achieved by applying a down-sampling operation prior to encoding. However, since high resolution depth maps are also needed for depth-based 3D coding tools, such as view synthesis prediction, an upsampling method that is able to recover the loss of ...
Equipment C. Trinitis Lehrstuhl f ur Rechnertechnik und Rechnerorganisation Institut f ur Informatik Technische Universit at M unchen GERMANY Abstract The goal of nding an optimal electric eld strength distribution for arbitrary three dimensional problems can be achieved by utilizing a parametric CAD modelling system that needs to be coupled with a three dimensional electric eld calculation...
Standardization of high voltage electric transmission line siting methodologies, by using GIS spatial analysis tools, has great potential in helping predict and defend new optimal route corridors. A standard methodology that incorporates multiple weighted perspectives of influence can aid in the route approval by the governmental and regulating permitting entities and the support of the affecte...
