## The recombination equation for interval partitions

2015
Michael Baake, Elham Shamsara,

The general deterministic recombination equation in continuous time is analysed for various lattices, with special emphasis on the lattice of interval (or ordered) partitions. Based on the recently constructed [4] general solution for the lattice of all partitions, the corresponding solution for interval partitions is derived and analysed in detail. We focus our attention on the recursive struc...

## The Nonlinear Schrödinger Equation on the Interval

2000
S. Fokas,

Let q(x, t) satisfy the Dirichlet initial-boundary value problem for the nonlinear Schrödinger equation on the finite interval, 0 < x < L, with q 0 (x) = q(x, 0), g 0 (t) = q(0, t), f 0 (t) = q(L, t). Let g 1 (t) and f 1 (t) denote the unknown boundary values q x (0, t) and q x (L, t), respectively. We first show that these unknown functions can be expressed in terms of the given initial and bo...

## The mKdV equation on a finite interval

2003
Anne Boutet, Dmitry Shepelsky,

We analyse an initial-boundary value problem for the mKdV equation on a finite interval by expressing the solution in terms of the solution of an associated matrix Riemann-Hilbert problem in the complex k-plane. This Riemann-Hilbert problem has explicit (x, t)-dependence and it involves certain functions of k referred to as “spectral functions”. Some of these functions are defined in terms of t...

## State Equation for Interval-Timed Petri Nets

2011
Louchka Popova-Zeugmann, Elisabeth Pelz,

Timed Petri Nets (also called Duration Petri Nets, DPNs) [7, 8] are a commonly used class for modeling formally complex technical systems as embedded real time systems, for instance in aeronautics. Engineers stated that intervals allowing some variable duration of events would be a more realistic view, so Interval-Timed Petri Nets (ITPNs) have been proposed as generalizations in [2]. Hierarchic...

## Modified F-Expansion Method Applied to Coupled System of Equation

2013
A. Aasaraai, M.B. Mehrlatifan, S. Khaleghizadeh,

A modified F-expansion method to find the exact traveling wave solutions of  two-component nonlinear partial differential equations (NLPDEs) is discussed. We use this method to construct many new solutions to the nonlinear Whitham-Broer-Kaup system (1+1)-dimensional. The solutions obtained include Jacobi elliptic periodic wave solutions which exactly degenerate to the soliton solutions, triangu...

## synthesis of platinum nanostructures in two phase system

پایان نامه :وزارت علوم، تحقیقات و فناوری - دانشگاه یاسوج - دانشکده علوم پایه 1390

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...

## Effect of Remote Back-Up Protection System Failure on the Optimum Routine Test Time Interval of Power System Protection

2013

Appropriate operation of protection system is one of the effective factors to have a desirable reliability in power systems, which vitally needs routine test of protection system. Precise determination of optimum routine test time interval (ORTTI) plays a vital role in predicting the maintenance costs of protection system. In the most previous studies, ORTTI has been determined while remote bac...
