In order to obtain the thermal characteristics of electric vehicle connector in operation. Firstly, circuit diagram is obtained by using thermoelectric simulation method. Then, based on Newton?s cooling equa?tion, natural-convection heat transfer coefficient calculated, which provides accurate input parameters for calculation. Finally, performance and influence component size material are analy...

In a previous paper we have introduced a method that allows one to combine decision procedures for uniiability in disjoint equa-tional theories. Lately, it has turned out that the prerequisite for this method to apply|namely that uniication with so-called linear constant restrictions is decidable in the single theories|is equivalent to requiring decidability of the positive fragment of the rst ...

We introduce rewriting with two sets of rules, the rst interpreted equa-tionally and the second not. A semantic view considers equational rules as deening an equational theory and reduction rules as deening a rewrite relation modulo this theory. An operational view considers both sets of rules as similar. We introduce suucient properties for these two views to be equivalent (up to diierent noti...

In this paper, 1-lump solution and 2-lump of a (2 + 1)-dimensional Sawada-Kotera-like equation are obtained by means the Hirota’s bilinear method long wave limit method. The propagation orbits, velocities collisions among waves analyzed. By setting parameter values, dynamic characteristics solutions shown in 3D density plots. These conclusions enrich dynamical theory higher-dimensional nonlinea...

We consider the Knizhnik-Zamolodchikov system of linear differential equations. The coefficients of this system are rational functions generated by elements of the symmetric group S n. We assume that parameter ρ = ±1. In previous paper [5] we proved that the fundamental solution of the corresponding KZ-equation is rational. Now we construct this solution in the explicit form.

abstract. in this paper, we implement numerical solution of differential equations of frac- tional order based on hybrid functions consisting of block-pulse function and rationalized haar functions. for this purpose, the properties of hybrid of rationalized haar functions are presented. in addition, the operational matrix of the fractional integration is obtained and is utilized to convert compu...

We study properties of solitary wave solutions of three evolution equations arising in the modeling of internal waves Our experiments indicate that broad classes of initial data resolve into solitary waves but also suggest that solitary waves do not interact exactly thus suggesting two of these equa tions are not integrable In the course of our numerical simulations interesting meta stable quas...
