The weld quality is highly related to the thermal history of and there have been many trials monitor using an infrared (IR) sensor. To obtain real temperature a surface based on brightness values measured by IR camera, emissivity value must be derived. For accurate assessment emissivity, one aware melting point isotherm. profiles only depend three factors during laser processing, specified as c...

Purpose This study investigated the anterior ocular anatomic origin of high-order aberration (HOA) components using optical coherence tomography and a Shack-Hartmann wavefront sensor. Methods A customized system was built to simultaneously capture images of ocular wavefront aberrations and anterior ocular biometry. Relaxed, 2-diopter (D) and 4-D accommodative states were repeatedly measured i...

Improving the spatial resolution in optical microscopes is a challenging task for many applications. In fluorescence confocal microscopy, the resolution is given by a lenght Detection Efficiency Function (DEF) which looks like a rice grain. 4Pi type C microscope has shown to be a powerful solution for considerably reducing the axial dimension of the DEF [1] and even its lateral dimension [2]. T...

The aim of this paper is to solve the fixed point problems : v = Ov, with Ov(x) def = max(Lv(x), Bv(x)), x ∈ E , (1) where E is a finite set, L is contractive and B is a nonexpansive operator and v = Ov, with Ov(x) def = max(sup w Lv(x), sup z Bv(x)), x ∈ E , (2) where W and Z are general control sets, the operators L are contractive and operators B are nonexpansive. For these two problems, we ...

In this paper, first a short history of the notion of equilibrium problem in Economics and Nash$acute{'}$ game theory is stated. Also the relationship between equilibrium problem among important mathematical problems like optimization problem, nonlinear programming, variational inequality problem, fixed point problem and complementarity problem is given. The concept of generalized pseudomonoton...

Objective(s): In this study we evaluate the impact of the different aspects of Gold Nano-Particles (GNPs) on the target absorptive Dose Enhancement Factor (DEF) during external targeted radiotherapy with photon beams ranging from kilovolt to megavolt energies using Monte Carlo simulation. Methods: We have simulated the interaction of photon beams wi...

in this paper, a numerical method for nding minimal solution of a mn fullyfuzzy linear system of the form ax = b based on pseudo inverse calculation,is given when the central matrix of coecients is row full rank or column fullrank, and where a~ is a non-negative fuzzy mn matrix, the unknown vectorx is a vector consisting of n non-negative fuzzy numbers and the constant b isa vector consisti...

Background: To enhance the dose to tumor, the use of high atomic number elements has been proposed.Objective: The aim of this study is to investigate the effect of gold nanoparticle distribution on dose enhancement in tumor when the tumor is irradiated by typical monoenergetic X-ray beams by considering homogeneous and inhomogeneous distributions of gold nanoparticles (GNPs) in the tumor.Method...
