Abstract In this paper, a nonlinear elliptic obstacle problem is studied. The nonhomogeneous partial differential operator generalizes the notions of p -Laplacian while on right hand side we have multivalued convection term (i.e., reaction may depend also gradient solution). main result paper provides existence solutions as well bondedness and closedness set weak problem, under quite general as...

in this paper, we calculate electron and hole impactionization coefficients in in0.52al0.48as using a monte carlo modelwhich has two valleys and two bands for electrons and holesrespectively. also, we calculate multiplication factor for electronand hole initiated multiplication regimes and breakdown voltagein in0.52al0.48as pin avalanche photodiodes. to validate themodel, we compare our simulat...

Drilling and blasting have numerous applications in the civil and mining engineering. Due to the two major components of rock masses, namely the intact rock matrix and the discontinuities, their behavior is a complicated process to be analyzed. The purpose of this work is to investigate the effects of the geomechanical and geometrical parameters of rock and discontinuities on the rock mass blas...

Single-pixel imaging (SPI) utilizes a second-order correlation of structured illumination light field and single-pixel detector to form images. As the provides no spatial resolution, generated by devices such as modulator substitutes role array camera retrieve pixel-wise information. Due its unique modality, SPI has certain advantages. Meanwhile, counterintuitive configuration reciprocity relat...

Stress concentration factors have been examined in a functionally graded material (FGM) plate with central holes in different shapes in this essay. The material properties change along the thickness of plate. ABAQUS software has been utilized for modeling of problem in which subroutine of ABAQUS sub-program was used for modeling of the targeted material. The considering shapes for hole in plate...

the drilling is well known as one of the most common hole making processes in the industry.due to close tolerance requirement for drilled holes in the most of work pieces, onlinecontrolling of the diameter of drilled holes seems to be necessary. in the current work, an onlinedimensional controlling system was developed for drilling process. doing this, drilling processwas executed in different ...
