This paper is devoted to the solution of the time-dependent Vlasov–Maxwell equations in singular geometries, i.e. when the boundary includes reentrant corners or edges. Indeed, computing the electromagnetic fields in this case is a challenge per se, as these geometrical singularities generate...

The international roughness index (IRI) for evaluating pavement surface roughness is simulated using the power spectral density (PSD) of pavement surface fluctuation. Quarter-car models recommended by the World Bank for measuring pavement roughness are adopted to simulate vehicle response....

This paper presents an integrated artificial neural network-computer simulation (ANNSim) for optimization of G/G/K queue systems. The ANNSim is a computer program capable of improving its performance by referring to production constraints, system's limitations and desired targets. It is a goal...

A computer model based on mass and energy balance has been developed which incorporates a range of solar flat plate air heating collector geometries and a drying model based on the thin layer drying principle. This model will be useful in understanding the extreme complexity of the drying...

Advanced computer simulation tools for analyzing daylighting features and thermal performance of buildings are improved at the Fraunhofer Institute for Solar Energy Systems. For an analysis of daylighting elements in lighting simulations, new light-deflecting structures and materials have been...

The consensus of the '92 Rio summit was that all development should aim for non-depletion of the earth's resources.The major growth region for the next decade is SE Asia and particularly the cities of South China for which Hong Kong is a role model with its dense urban construction. Recent Hong...

The performance of microwave-assisted fluidized bed drying of soybeans was simulated (using a previously validated mathematical model) and analyzed based on the first- and second law of thermodynamics. The energy and exergy analysis were carried out for several drying conditions. The effects of...

A dome-covered house is an example of designing sustainable buildings by learning from the optimized biological forms from the nature. The paper presents a 3-D thermal and air flow (3D-TAF) model that estimates the energy needs of a dome-covered house. The model is verified with CFD simulations...

This study analyzes classrooms, built according to a standard project of public schools in the Brazilian State of Paraná, concerning their luminic qualities. The daylighting analysis was based on computational simulations with daylighting programs, for different combinations of days, schedules...

The goal of this paper is to contribute to understanding the behaviour of the photovoltaic (PV) sector in Spain and its expectations under possible scenarios. Currently, PV solar energy is not a profitable sector by itself. Therefore, the Spanish government, like the governments of other...
