The transmission properties of X-ray in a straight capillary were studied by computer simulation with the Ray-Tracing program SHADOW. The simulation was done for 30keV photons in a SiO2 capillary with perfect smooth inner surface. The simulation indicates an effect collimation of X-rays by the...

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...

In this paper, the proposed constraint method in conjunction with Lagrange’s equation systematically to discretize and simulate for large-scale systems is illustrated by application of a rotating Euler–Bernoulli beam. A good truncation procedure based on the system eigenvalues for this...

Two methods, i.e. computer simulation and field measurement, are used in this paper to investigate dynamic pavement loading (DPL) generated by vehicle–pavement interaction. A profilometer is used for measuring road surface roughness. Based on the power spectral density of the measured surface...

In a through-process hot steel rolling, the material moves from the reheat furnace to the rolling stands, and finally to the runout table. In this work, the pseudo-bond graph model has been developed to predict the temperature distribution in this process, which includes the study of essential...

Controlled release of nutrients from coated fertilizer granules is desired for optimal uptake by plants and crops. We study the saturation and release of nutrients from a coated spherical fertilizer granule having varying contact areas with the soil using the techniques of mathematical modeling...

This paper presents a study which was conducted on the effect of a robot's geometrical parameters on its dynamic performance under different balancing conditions. This research was undertaken in pursuit of an optimal dynamic performance of industrial robots. In this study an indicator was...

Ray-tracing program SHADOW was used to simulate X-ray propagation in capillaries with cylindrical, tapered and polynomial profiles. The results indicate efficient concentration of X-ray beams by all of these capillaries. The influences on transmission properties from geometry parameters of...
