The latency insertion method (LIM) is a transient simulation technique for circuits and is based on a finite-difference formulation, like the well-known finite-difference time-domain (FDTD) method for solving Maxwells equations. The LIM, like the FDTD method, is only conditionally stable resulting in an upper bound for the time step of the transient simulation. This bound on the time step is a ...

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...

using the mean-value theorem for integrals we tried to solved the nonlinear integral equations of hammerstein type . the mean approach is to obtain an initial guess with unknown coefficients for unknown function y(x). the procedure of this method is so fast and don't need high cpu and complicated programming. the advantages of this method are that we can applied for those integral equation...

معادلات انتگرال دیفرانسیل در مدل بندی مسائلی کاربردی چون انتقال گرما، پدیده انتشار و پخش نوترون مورد استفاده قرار می گیرند و نیز در برخی کاربردهای فیزیک و زیست شناسی و مهندسی استفاده وافر دارند و به تبع آن معادلات انتگرال دیفرانسیل فازی نیز مورد توجه قرار گرفته اند. معادله انتگرال دیفرانسیل غیر خطی زیر را در نظر می گیریم. در صورتی که توابع معلوم a(t)و k(t,s,x(t)) و f(t,x(t)) توابعی ف...
