In this work, the triple convolution of Daubechies wavelet is used to solve the three dimensional (3D) microscale Dual Phase Lag (DPL) problem. Also, numerical solution of 3D time-dependent initial-boundary value problems of a microscopic heat equation is presented. To generate a 3D wavelet we used the triple convolution of a one dimensional wavelet. Using convolution we get a scaling function ...
سابقه و هدف: نارسایی عملکردی دریچه میترال (Functional mitral regurgitation, FMR) به علت تغییر شکل بطن چپ، کشیده شدن (Tethering) و محدب شدن (Tenting) لت قدامی دریچه میترال عارض میشود. بیماری عروق کرونر یکی از دلایل مهم FMR بهدلیل کشیده شدن است. تعیین FMR و شدت آن یکی از عوامل مهم پیشآگهی بیماران است. روشهای متعددی برای تعیینFMR و شدت آن وجود دارد، از جمله این روشها، اندازهگیری سطح زیر تحدب ...
For one dimensional SU(n) Hubbard model, a pair of Lax operators are derived, which give a set of fundamental equations for the quantum inverse scattering method under both periodic and open boundary conditions. This provides another proof of the integrability of the model under periodic boundary condition. PACS Numbers: 46.10.+z, 05.40.+j, 05.60.+w e-mail: [email protected] Integrable strong...
We study a generalization of the hierarchy of mKdV equations (modi-ed KdV), which forms an integrable system. This generalization is based on a Lax operator associated to the equations, with principal components of degrees between ?3 and 0. The main result of the study is the com-mutation of the classical integrals of motion. For that purpose, one can construct an isomorphism between the space ...
We have introduced, in a previous paper, the fundamental lax 2-category of a ‘directed space’ X. Here we show that, when X has a T1-topology, this structure can be embedded into a larger one, with the same objects (the points of X), the same arrows (the directed paths) and the same cells (based on directed homotopies of paths), but a larger system of comparison cells. The new comparison cells a...
