مقدمه و هدف : از زمانی که خواص فیزیکی ni-ti در سال 1988 شرح داده شده است، فایل های روتاری نیکل-تیتانیوم (ni-ti) به طور گسترده در درمان های اندودنتیک استفاده می شوند. این فایل ها مزایای زیادی نسبت به فایل های استنلس استیل (stainless steel) دارند. علی رغم این مزایا به نظر می رسد فایل های ni-ti نسبت به شکستن آسیب پذیرتر هستند. اخیرا فایل های نیکل تیتانیوم reciprocating معرفی شده ادعا می کنند مقاوم...
a generalization of the known results in fusion frames and $g$-frames theory to continuous fusion frames which defined by m. h. faroughi and r. ahmadi, is presented in this study. continuous resolution of the identity (cri) is introduced, a new family of cri is constructed, and a number of reconstruction formulas are obtained. also, new results are given on the duality of continuous fusion fram...
this paper deals with continuous frames and continuous riesz bases. we introduce continuous riesz bases and give some equivalent conditions for a continuous frame to be a continuous riesz basis. it is certainly possible for a continuous frame to have only one dual. such a continuous frame is called a riesz-type frame [13]. we show that a continuous frame is riesz-type if and only if it is a con...
the morphology of retinal photoreceptor layer was studied in continuous light-exposed and dark-adapteddomestic male cats (felis catus). the eyes of 12 healthy adult cats (4 in continuous light-exposed group, 4 in continuous dark-adapted group, and 4 in control group) were routinely fixed and studied by electron microscope. results showed that the general structure of photoreceptor layer in this...
the aim of this paper is to prove a common fixed point theorem for nonexpansive type single valued mappings which include both continuous and discontinuous mappings by relaxing the condition of continuity by weak reciprocally continuous mapping. our result is generalize and extends the corresponding result of jhade et al. [p.k. jhade, a.s. saluja and r. kushwah, coincidence and fixed points of ...
in this paper we introduce continuous $g$-bessel multipliers in hilbert spaces and investigate some of their properties. we provide some conditions under which a continuous $g$-bessel multiplier is a compact operator. also, we show the continuous dependency of continuous $g$-bessel multipliers on their parameters.
the aim of this paper is to introduce the concepts of fuzzy upper and fuzzy lower almost continuous, weakly continuous and almost weakly continuous multifunctions. several characterizations and properties of these multifunctions along with their mutual relationships are established in $l$-fuzzy topological spaces
در این پایان نامه ابتدا بانیم گروه های توپولوژیکی ونیم توپولوژیکی و گروه های پیرا توپولوژیکی و مفاهیم چند از آنها آشنا می شویم. سپس با بررسی ویژگی های نیم گروه های توپولوژیکی، گروه های پیرا توپولوژیکی در پی شرایطی خواهیم بود اگر یک نیم گروه توپولوژیکی با یک گروه پیرا توپولوژیکی دارای آن باشد، خود یک گروه توپولوژیکی شود. در ادامه نیم گروه های توپولوژیکی معکوس را بررسی ودر پی شرایطی هستیم که نگاش...
context-dependent modeling is a well-known approach to increase modeling accuracy in continuous speech recognition. the most common way to implement this approach is via triphone modeling. nevertheless, the large number of such models results in several problems in model training, whilst the robust training of such models is often hardly obtained. one approach to solve this problem is via param...
assume ? ? l2(rd) has fourier transform continuous at the origin, with ˆ ?(0) = 1, and thatcan be represented by an affine series f = j>0 k?zd c j,k?j,k for some coefficients satisfying c 1(2) = j>0 k?zd |c j,k|2 1/2 <?. here ?j,k(x) = |deta j |1/2?(a jx ?k) and the dilation matrices a j expand, for example a j = 2j i. the result improves an observation by daubechies that t...
