modeling and simulation of communication circuits at high frequency are important challenges ahead in the design and construction of these circuits. knowing the fact that the lumped element model is not valid at high frequency, distributed analysis is presented based on active and passive transmission lines theory. in this paper, a lossy transmission line model of traveling wave switch (twsw) i...

in this article, by using chebyshev’s polynomials and chebyshev’s expansion, we obtain the best uniform polynomial approximation out of p2n to a class of rational functions of the form (ax2+c)-1 on any non symmetric interval [d,e]. using the obtained approximation, we provide the best uniform polynomial approximation to a class of rational functions of the form (ax2+bx+c)-1 for both cases b2-4a...

We study the matrix completion problem when observation pattern is deterministic and possibly non-uniform. propose a simple efficient debiased projection scheme for recovery from noisy observations analyze error under suitable weighted metric. introduce function of weight sampling that governs accuracy recovered matrix. derive theoretical guarantees upper bound nearly matching lower bounds show...

Abstract A Ginzburg–Landau model is developed that adequate to describe a square-to-rectangle martensitic transition with associated shape-memory and superelastic properties. Using this we study caloric effects in the vicinity of induced by stress compare case uniform uniaxial non-uniform continuous distribution stresses produce bending material. The former corresponds an elastocaloric effect l...
