we commence by using from a new norm on l1(g) the -algebra of all integrable functions on locally compact group g, to make the c-algebra c(g). consequently, we find its dual b(g), which is a banach algebra so-called fourier-stieltjes algebra, in the set of all continuous functions on g. we consider most of important basic theorems about this algebra. this consideration leads to a rather com...
This paper addresses 2-D mesh-based object tracking and mesh-based object mosaic construction for synthetic transguration of deformable video objects with deformable boundaries in the presence of another occluding object and/or self-occlusion. In particular, we update the 2-D triangular mesh model of a video object incrementally to account for the newly uncovered parts of the object as they are...
this study investigated the effects of planning on second-language written production with regard to task type. the participants were 75 iranian learners of english as a foreign language attending a private foreign language institution. they were asked to complete two different types of writing tasks (expository writing task and argumentative writing task) in different planned conditions (indiv...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
from historical facts to geo-political realities: relation between turkey and armenia ( 1915 – 2010)
armenias geopolitics and its historical experience have had a determining impact on the character of its foreign policy .present-day armenia is a small, landlocked country with _11,620 square miles area armenias landlocked nature makes it dependent on the benevolence of its neighbors for access to the outside world a fact that gives it a sense of isolation and vulnerability. as it was indic...
چکیده: در بخش اول این پروژه تحقیقاتی، از واکنش ترکیب 2-متیل ایزوتیواورنیوم هیدروژن سولفات (1) با 2-(اتوکسی? متیلن) مالونیتریل (a2)، ترکیب 4-آمینو-2-(متیل?تیو)پیریمیدین-5-کربونیتریل (3) حاصل می?آید. ترکیب 3 در واکنش با انیدرید استیک و انجام نوآرایی دیمروث تبدیل به پیریمیدوپیریمیدین (5) می?شود. واکنش جایگزینی نوکلئوفیلی آمین?های نوع دوم برروی موقعیت c-2 حلقه پیریمیدین مشتقات جدیدی از پیریمیدو[4,...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
فرض کنیم a یک *c-جبر سه تایی باشد. نگاشت c-دوخطی t : a × a ? a را یک *c-دومضروب جبرهای سه تایی می نامیم اگر به ازای هر a, b, c, d ? a در [t([a, b, c], d) = [t(a, b), c, d و [(t(a, [b, c, d]) = [a, b, t(c, d صدق کند. همچنین نگاشت c-دوخطی t : a × a ? a را *c-دومضروب جردن جبرهای سه تایی می نامیم اگر به ازای هر a ? a در [t([a, a, a], a) = [t(a, a), a, a و [(t(a, [a, a, a]) = [a, a, t(a, a ص...
Object recognition is a subproblem of the more general problem of perception, and can be defined as follows. Given a scene consisting of one or more objects, can we identify and localize those objects that are sufficiently visible to the sensory system? It is generally assumed that a description of each object to be recognized is available to the computer and can be used to facilitate the task ...
