هدف از این پایان نامه تعمیم قضایای بوهلر (1969)، هید (1971) و هید - براون (1971) در یک فرایند شاخه ای با محیط تصادفی است. برای فرایند شاخه ای $ lbrace z_{n} brace _ {ngeq0 } $ ، با فرض $ z_{0}=1 $ و $ m= e(z_{1}) in (0,infty) $، می دانیم $ w_{n}=z_{n}/m^{n} $ یک مارتینگل نامنفی و تقریبا مطمئن به متغیر تصادفی $ w_{infty} $ همگراست. برای نرخ همگرایی این مارتینگل، هید و بوهلر به ترتیب نتیجه گرف...
Last decade, numerous giant data center networks are built to provide increasingly fashionable web applications. For two integers m≥0 and n≥2, the m-dimensional DCell network with n-port switches Dm,n n-dimensional BCDC Bn have been proposed. As a generalization of connectivity, structure (substructure) connectivity was recently Let G H be connected graphs. F set whose elements subgraphs G, eve...
Introduction: Entrepreneurship is a long term educational and training process which necessitates the planning in Iran's educational system especially in universities and higher education institutes. Thereby since 2001, the KARAD project (Entrepreneurship Development in Universities) was started by ministry of sciences, research and technology. However in universities affiliated to health minis...
the existence of an organization depends on communications and this is an area that managers spend most of their time on. therefore, recognition of communication skills accompanied with its implementation is among the essential parameters of successful management in any organization. in this study we decided to determine the relationship between managers' communication skills and health of orga...
this study concerns about quantum chemical modeling behavior of 02 on cr (100)surface by using density functional theory (dft) by lanl2dz and 6 — 31g* basissets, we presented the results of our first principles electronic structure calculationson the 02 molecules and their interface with cr (100) surface. the chromium metalhas the body-centered cubic structure, and chromium cluster has five cr ...
let $g$ be a finite group and $z(g)$ be the center of $g$. for a subset $a$ of $g$, we define $k_g(a)$, the number of conjugacy classes of $g$ which intersect $a$ non-trivially. in this paper, we verify the structure of all finite groups $g$ which satisfy the property $k_g(g-z(g))=5$ and classify them.
