The boundaryless beam propagation method uses a mapping function to transform the infinite real space into a finite-size computational domain [Opt. Lett.21, 4 (1996)]. This leads to a bounded field that avoids the artificial reflections produced by the computational window. However, the method suffers from frequency aliasing problems, limiting the physical region to be sampled. We propose an ad...

Thus far, simulations have failed to predict accurately electrostatic powder charging during pneumatic transport. We advanced the modeling of flow by a three-part study: first, we shot individual particles on metal target and measured exchanged charge. Second, based these results, formulated an empirical model implemented it in our CFD tool. Using this tool, performed large-eddy through square ...

The paper presents the results of tests carried out to validate a new method for evaluating uncertainty coordinate measurements categorised as Sensitivity Analysis (SA). This concerns measuring dimensions and geometrical deviations. Measurement is evaluated on basis information given in Maximum Permissible Error (MPE) formula Coordinate Measuring Machine (CMM). models express measured character...

Two generalized mathematical models with memory for the concentration of tumor cells have been analytically studied using cylindrical coordinate and integral transform methods. The generalization consists formulating two Caputo-time fractional derivative, that are suitable to highlight influence history evolution on present behavior cancer cells. time-oscillating has considered boundary domain....
