This paper describes a X-rays detector based on an array of scintillator crystals, CsI:Tl, encapsulated in well-type silicon. The X-ray energy is first converted to visible light which is detected by a photodetector in the well bottom. DRIE techniques are used to achieve perfect vertical sidewalls 515 m deep, 100 m pixel square size and to maximize the fill factor. The inner walls of the well a...
We initiate the study of 2.5D box visibility representations (2.5D-BR) where vertices are mapped to 3D boxes having the bottom face in the plane z = 0 and edges are unobstructed lines of sight parallel to the xor y-axis. We prove that: (i) Every complete bipartite graph admits a 2.5D-BR; (ii) The complete graph Kn admits a 2.5D-BR if and only if n 6 19; (iii) Every graph with pathwidth at most ...
Dead zones in the coastal oceans have spread exponentially since the 1960s and have serious consequences for ecosystem functioning. The formation of dead zones has been exacerbated by the increase in primary production and consequent worldwide coastal eutrophication fueled by riverine runoff of fertilizers and the burning of fossil fuels. Enhanced primary production results in an accumulation o...
Dans une permutation, un record est maximum ou minimum, en partant de la droite gauche. Les éléments d’une permutation peuvent être classés deux types : les records (dits points extérieurs) et autres intérieurs). permutations sans point intérieur ont été étudiées sous le nom carrées. Ici, nous explorons ayant nombre fini intérieurs, dites quasi-carrées. Contrairement aux carrées, l’énumération ...
in this study, mixed convection heat transfer and local and global entropy generation in aventilated square cavity have been investigated numerically. the natural convection effect isachieved by a constant heat flux imposed at the bottom wall and cooled by injecting a coldfollow. in order to investigate the effect of port location, four different placementconfigurations of the inlet and outlet ...
several investigations have been devoted towards understanding the coating process in fluidized beds. most of these studies focused on spraying liquid droplets over the bed. however, due to the complexity of these systems, more investigations are still required to quantify the effect of operating conditions on the coating criteria. the present work aims at fundamentally understanding and precis...
in the present research mixed convection flow through a copper-water nanofluid in a driven cavity in the presence of magnetic field is investigated numerically. the cavity is heated from top and cooled from bottom while its two vertical walls are insulated. the governing equations including continuity, n-s and energy equations are solved over a staggered grid system. the study is conducted for ...
The size selectivity and catch pattern of Trichiurus lepturus in 40 mm diamond square mesh codends were investigated this study. A 34 m high opening trawl was used, which is a common design used by fishermen operating along the northwest coast India, cover codend method employed to determine selectivity. Along with changes length at 50% retention rate for usage codends, indicators understand ex...
