The start-stop approximation is a standard tool for processing radar data in synthetic aperture imaging. It assumes that the antenna is motionless when a pulse is emitted and the scattered signal received, after which the antenna moves to its next sending/receiving position along the flight track. However, when the antenna is mounted on a satellite, as opposed to an airplane, its relatively hig...
ردیابی بر مبنای هسته اصلی بهینه شده با بکارگیری الگوریتم mean shift توجه زیادی را به عنوان یک تکنیک موثر ردیابی در رشته های ویدئویی کسب کرده است. الگوریتم mean shift اساساً یک روش بهینه سازی صعود گرادیان است، که برای پیدا کردن بابهای محلی طراحی شده است. در بسیاری از ردیابی ها، ما نیاز به جستجوی باب کلی یک تابع هدف داریم، مانند وقتیکه جابجایی هدف در بین فریم های متوالی نسبتاً بزرگ باشد بطوریکه هیچ...
Background and Objectives: Peritonitis is one of the most important emergency abdominal surgeries which mostly occurs due to intra-abdominal visceral perforation. Case Presentation: The patient was a 54-year-old man referred to the emergency department for abdominal pain and inability in passing gas and defecation. In physical examination, there was a generalized tenderness with guarding; in t...
in this paper, we introduce and study the notion of precompacttopological generalized groups and some new results are given.
given a mapping $f:xto x$ we naturally associate to it a monotonic map $gg_f:exp xto exp x$ from the power set of $x$ into itself, thus inducing a generalized topology on $x$. in this paper we investigate some properties of generalized topologies which are defined by such a procedure.
In this review, we discuss the use of a variety of 3-D models (particularly 3-D skin, lung, breast and endothelial) in radiobiological research and highlight the differences in responses compared to 2-D culturing conditions (monolayers). We review the characteristics of existing 3-D models and aim to point out the substantial advantages 3-D cultures provide for modern radiobiology. In particula...
in this paper, using a generalized translation operator, we prove theestimates for the generalized fourier-bessel transform in the space l2 on certainclasses of functions.
let $a_1$, $a_2$ be unital banach algebras and $x$ be an $a_1$-$a_2$- module. applying the concept of module maps, (inner) modulegeneralized derivations and generalized first cohomology groups, wepresent several results concerning the relations between modulegeneralized derivations from $a_i$ into the dual space $a^*_i$ (for$i=1,2$) and such derivations from the triangular banach algebraof t...
