The present paper is devoted to the application of the space transformation techniques for solving linear programming problems. By using a surjective mapping the original constrained optimization problem is transformed to a problem in a new space with only equality constraints. For the numerical solution of the latter problem the stable version of the gradient-projection and Newton's methods ar...

A comprehensive study of Schottky barrier MOSFET (SBMOSFET) scaling issue is performed to determine the role of wafer orientation and structural parameters on the performance of this device within Non-equilibrium Green's Function formalism. Quantum confinement increases the effective Schottky barrier height (SBH). (100) orientation provides lower effective Schottky barrier height in compa...

This paper investigates a multi-period rectilinear distance 1-center location problem considering a line-shaped barrier, in which the starting point of the barrier follows the uniform distribution function. In addition, the existing points are sensitive to demands and locations. The purpose of the presented model is to minimize the maximum barrier distance from the new facility to the existing ...

The modern view of the mammalian bloodbrain barrier (BBB) has shifted from a purely anatomic concept to a more physiological and dynamic definition. Morphologically, the BBB is formed by specialized endothelial cells (ECs) lining the intraluminal portion of brain capillaries. These ECs are characterized by specialized regions of intercellular contact (tight junctions) that prevent leakage of bl...

although in recent two decades, the concept of dielectric barrier discharges (dbds) have been developed in ozone production well, air pollution control, plasma screens and control of chemical, and biological and medical processes, employment of this concept for high voltage applications to improve insulation performance as an alternative to the pressurized gas-insulated systems (gis) utilizing ...

improving barrier properties through the use of nanocomposites is an important area of research, especially for the food packaging industry. in this work, titanium dioxide (tio2 )/low density poly ethylene (ldpe) nanocomposites were synthesized as the oxygen barrier layers through the co-extrusion process. the oxygen permeability of the nanocomposite with 4% of tio2 decreased for about 16% comp...
