مدل روزنه های موازی موج دار (corrugated oarallel bundle model) برای تعریف اثر ساختمان روزنه ها در نفوذ-واکنش (diffusion and reaction) در کاتالیستهای متخلخل بکار می رود. در مدل روزنه های موج دار، از یک دسته روزنه های اصلی (pore) استفاده شده است . هر یک از این روزنه های اصلی دارای یکسری عناصر روزنه می باشد که هر عنصر دارای یک شعاع تعیین شده به صورت اتفاقی از یک توزیع اندازه روزنه ها (pore size di...

elastic energy of seismic wave is lost through propagation into the earth. various factors affect seismic energy. some of them are frequency independent and recovered in processing steps. but other factors such as intrinsic absorption of medium are frequency dependent and cannot be recovered by processing methods. lost energy caused by these factors is called attenuation. there are various meth...

Purpose: As the world rapidly moves into the new era of information and wisdom, the needs of human beings to use books and libraries continue to grow. With this in mind, in addition to increasing public library services, it's important for planners to distribute library facilities equitably across the country.

We consider a sequence of Dirichlet problems in varying domains (or, more generally, of relaxed Dirichlet problems involving measures in M 0 (Ω)) for second order linear elliptic operators in divergence form with varying matrices of coefficients. When the matrices H -converge to a matrix A , we prove that there exist a subsequence and a measure μ in M 0 (Ω) such that the limit problem is the re...
