We revisit the doubly-layered sandwich detector con guration for single-shot dual-energy x-ray imaging. In order to understand its proper operation, we investigated the contrast-to-noise performance in terms of the x-ray beam setup using the Monte Carlo methods. Using a pair of active photodiode arrays coupled to phosphor screens, we have built a sandwich detector. For better spectral separatio...

The structural design problems are acknowledged to be commonly multicriteria in nature. The various multi-criteria optimization methods are reviewed and most efficient and easy-to-use Pare to optimal solution method is applied to structural optimization of a sandwich beam.

Euler, Timoshenko and high shear deformation theories to analyze the free vibration of functionally graded (FG) beam were developed. The mechanical properties this assumed differ in thickness direction according model a power-law distribution. principle Hamilton was used find equations motion. For vibration, analytical solution these presented using Navier method. effect power index, aspect rat...

Abstract We study the effect of a tangled sub-fG level intergalactic magnetic field (IGMF) on electrostatic instability blazar-induced pair beam. Sufficiently strong IGMF may significantly deflect TeV beams, which would reduce flux secondary cascade emission below observational limits. A similar reduction result from beam–plasma instability, operates best in absence IGMF. Considering with corre...

introduction: hydrocolloids are widely used in food systems as an emulsifying or stabilizing agent. one way to improve the emulsifying properties of hydrocolloids is complexation with proteins. in general, protein and hydrocolloid components may be combined together by either a) covalent bonding (conjugates) or b) electrostatic complexing. conjugates can be efficiently prepared during the stora...
