in this paper, we introduce the notion of ($epsilon $, $epsilon $ $vee$ q_{k})− fuzzy subnear-ring which is a generalization of ($epsilon $, $epsilon $ $vee$ q)−fuzzy subnear-ring. we have given examples which are ($epsilon $, $epsilon $ $vee$ q_{k})−fuzzy ideals but they are not ($epsilon $, $epsilon $ $vee$ q)−fuzzy ideals. we have also introduced the notions of ($epsilon $, $epsilon $ $vee$ ...

در این پژوهش تاثیر پارامتر سرعت بر افت فشار سیکلون و قطر ذرات بر بازده سیکلون با حدود 1300000 المان بصورت با سازمان تهیه شده است. برای ایجاد کوپل میان معادلات پیوستگی و ممنتوم از الگویتم سیمپل استفاده شده است. پروفیلهای سرعت در جهتهای y و z جریان در دو مقطع سیکلون با استفاده از مدلهای آشفتگی RNG k-ε، k-ε استاندارد و k-ε تحققپذیر محاسبه شدهاند و بههمراه نتایج تجرب...
In this paper, we will provide a simple method for starting with a given finite frame for an $n$-dimensional Hilbert space $mathcal{H}_n$ with nonzero elements and producing a frame which is $epsilon$-nearly Parseval and $epsilon$-nearly unit norm. Also, the concept of the $epsilon$-nearly equal frame operators for two given frames is presented. Moreover, we characterize all bounded invertible ...
The explosion in volume and variety of data offers enormous potential for research and commercial use. Increased availability of personal data is of particular interest in enabling highly customised services tuned to individual needs. Preserving the privacy of individuals against reidentification attacks in this fast-moving ecosystem poses significant challenges for a one-size fits all approach...
We fitted C(k,tau,epsilon) proportional to exp([-sigma(k,epsilon)tau] to time-correlation functions C(k,tau,epsilon) of structure factors S(k,t,epsilon) of shadowgraph images of fluctuations below a supercritical bifurcation at V(0)=V(c) to electroconvection of a planar nematic liquid crystal in the presence of a voltage V=sqrt[2]V(0)cos((2pift) [k=(p,q) is the wave vector and epsilon identical...
the design and optimization of hydrocyclones using cfd techniques are gaining popularity and the key to a successful simulation lies with the accurate description of the high turbulent swirling behavior of the flow. this paper presents a detailed comparison between the omega rsm and the rng k–e turbulence model, which are both derived specially for modeling swirling or rotational flow, in the s...
For any $\epsilon>0$, Laue and Matijevic [CCCG'07, IPL'08] give a PTAS for finding $(1+\epsilon)$-approximate solution to the $k$-hop MST problem in Euclidean plane that runs time $(n/\epsilon)^{O(k/\epsilon)}$. In this paper, we present an algorithm $(n/\epsilon)^{O(\log k \cdot(1/\epsilon)^2\cdot\log^2(1/\epsilon))}$. This gives improvement on dependency $k$ exponent, while having worse $\eps...
