target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
دراین پژوهش یک روش مسیریابی برحسب تقاضا، چند مسیره و بدون گره مشترک برای شبکههای اقتضایی ارائه شده است. الگوریتم ارائه شده توسعهای از پروتکل تک-مسیره aodv میباشد، بطوریکه چندین مسیر از یک گره مبدأ به یک گره مقصد ایجاد میکند که همه مسیرها از هم مجزا میباشند یعنی هیچ گره یا لینک مشترکی ندارند. هدف این تحقیق، ارزیابی و بهبود روشهای مسیریابی چند مسیره مبتنی بر پروتکلهای برحسب تقاضا بوده اس...
Este artigo apresenta o projeto de adaptação de métricas da ferramenta Coh-Metrix para o português do Brasil (Coh-Metrix-Port). Descreve as ferramentas de processamento de língua natural para o português que foram utilizadas, juntamente com as decisões tomadas para a criação da CohMetrix-Port. O artigo traz duas aplicações da ferramenta Coh-Metrix-Port: (i) a avaliação de textos jornalísticos e...
Resumo. Este artigo provê resultados iniciais sobre a tarefa de classificação automática de prioridade de tweets, como forma de amenizar a sobrecarga de informação sofrida por usuários do Twitter. Para tanto, aplicamos Máquinas de Vetor de Suporte a um extenso conjunto de exemplos contendo tweets manualmente classificados por nove usuários. Mostramos resultados promissores mesmo com a quantidad...
We introduce and study a new class of spaces, namely $beta-$topological vector spaces via $beta-$open sets. The relationships among these spaces with some existing spaces are investigated. In addition, some important and useful characterizations of $beta-$topological vector spaces are provided.
in this paper, we introduce the structure of a groupoid associated to a vector field on a smooth manifold. we show that in the case of the $1$-dimensional manifolds, our groupoid has a smooth structure such that makes it into a lie groupoid. using this approach, we associated to every vector field an equivalence relation on the lie algebra of all vector fields on the smooth...
tgiflx, a homoproteins cluster member located on the x chromosome, has a critical role in male reproduction and prostate development. previous studies have shown the erratic expression of tgiflx gene in a large proportion of prostate tumors. however tgiflx function in prostate development remains unknown. the purpose of this study was to evaluate the consequences of tgiflx expression on prostat...
