This paper presents a single facility location problem in the presence of a probabilistic line barrier. The aim of this problem is to minimize bi-objectives, namely the total expected barrier distance and the maximum expected barrier distance from each demand point to the new facility point. Based on our best knowledge, there is no such a mathematical model to present this problem in the litera...

Pulse progagation on nonlinear transmission lines (NLTLs), which are transmission lines with regularly spaced Schottky varactors, is investigated for the amplification of short pulses. It is found that the soliton developed in an NLTL experiences an exponential amplitude growth, when it couples with a co-existing voltage edge.

Introduction The bright signal of fluid and blood can affect tumor detection in screening applications. Diffusion weighted EPI is now frequently employed to attenuate these signals and highlight tumors. Gradient pulses can also be added to unbalanced SSFP sequences to attenuate the signals with motion. It has been demonstrated that SSFP sequence is strongly sensitive to self-diffusion or other ...

A left-handed transmission line with regularly spaced Schottky varactors is experimentally characterized. Due to dispersion, an envelop pulse on the line experiences a great distortion. By measuring the test line, we successfully observed that this distortion is compensated for by the nonlinear effects of Schottky varactors. This article describes the experimental observations, together with fu...

The three-dimensional propagation of electromagnetic waves in a distributed Schottky barrier transmission line is investigated. In one case, we show that the electromagnetic fields are similar to those that were originally obtained by Goubau and Schwering in their development of the beam waveguide. This case can lead to a very low-loss distributed Schottky barrier resonator.

Criteria containing a barrier function i.e., an unbounded function at the boundary of the feasible solution domain are frequently encountered in the optimization framework. When an iterative descent method is used, a search along the line supported by the descent direction through the minimization of the underlying scalar function has to be performed at each iteration. Usual line search strateg...

The complex structure of human skin and its physicochemical properties turn it into an efficient outermost defence line against exogenous factors, and help maintain homeostasis of the human body. This role is played by the epidermal barrier with its major part - stratum corneum. The condition of the epidermal barrier depends on individual and environmental factors. The most important biophysica...
