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...

Statistical Relational Learning (SRL) is a sub-area in Machine Learning which addresses the problem of performing statistical inference on data that is correlated and not independently and identically distributed (i.i.d.) { as is generally assumed. For the traditional i.i.d. setting, distribution free bounds exist, such as the Hoe ding bound, which are used to provide con dence bounds on the ge...

Neutron diffraction study of nanostructured magnetite was performed at room temperature. The actual grain-size was determined from evaluation of X-ray diffraction profiles by the modified Williamson-Hall plot. The atomic structure parameters and the sublattice magnetic moments were determined using the Rietveld refinement of the neutron diffraction spectra. The sublattice magnetization at the o...
