یک سه تائی (a, g, a) که در آن a یک -c0 جبر و g یک گروه موضعا فشرده و a یک همریختی از g به aut(a)، گروه خود ریختی های a که بطور قوی پیوسته باشد را یک سیستم دینامیکی c0- می گویند. فرض کنید (a, g, a) یک سیستم دینامیکی c0- باشد و b یک c0- زیر جبر پایا از a باشد. در این پایان نامه، ما می خواهیم ببنیم چه موقعی b xag در حالیکه b x g نمایش c0- ضرب خارجی از b بوسیله گروه موضعا فشرده g است ، همچنین اگر b...
An independent broadcast on a connected graph $G$is a function $f:V(G)to mathbb{N}_0$such that, for every vertex $x$ of $G$, the value $f(x)$ is at most the eccentricity of $x$ in $G$,and $f(x)>0$ implies that $f(y)=0$ for every vertex $y$ of $G$ within distance at most $f(x)$ from $x$.The broadcast independence number $alpha_b(G)$ of $G$is the largest weight $sumlimits_{xin V(G)}f(x)$of an ind...
within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...

building on previous studies on intellectual features and learners’ grammar learning, the present study aimed at investigating whether intelligence criterion had any impact on efl learners’ english grammar learning across two intelligence levels. in the current study, the participants were divided into two experimental and control groups by administration of raven i.q. test. this led to the for...
let g = (v, e) be a simple graph. hosoya polynomial of g isd(u,v)h(g, x) = {u,v}v(g)x , where, d(u ,v) denotes the distance between vertices uand v. as is the case with other graph polynomials, such as chromatic, independence anddomination polynomial, it is natural to study the roots of hosoya polynomial of a graph. inthis paper we study the roots of hosoya polynomials of some specific graphs.
مفهوم میانگین پذیری ریشه در آغاز نظریه اندازه مدرن دارد. پس از سال 1940 میانگین پذیری به یک مفهوم مهم در آنالیز هارمونیک تبدیل شد. جانسن ltrfootnote{johnson} کسی بود که نظریه میانگین پذیری جبرهای باناخ را ابداع کرد. اما مفهوم میانگین پذیری ضعیف اولین بار توسط دیلز ltrfootnote{dales} و همکارانش در cite{dales2} برای جبرهای باناخ جابجایی معرفی شد و توسط جانسن برای حالت ناجابجایی گستر...
this thesis is a study on insurance fraud in iran automobile insurance industry and explores the usage of expert linkage between un-supervised clustering and analytical hierarchy process(ahp), and renders the findings from applying these algorithms for automobile insurance claim fraud detection. the expert linkage determination objective function plan provides us with a way to determine whi...
