M M m K Queue With Additional Servers and Discouragement (RESEARCH NOTE)
(Materials and Energy Research Center, 20021101)Waiting in long queue is undesirable due to which in some practical situations customers become impatient and leave the system. In such cases providing additional servers can reduce long queue. This investigation deals ...

M m m Queue with Balking, Reneging and Additional Servers
(Materials and Energy Research Center, 20020601)In this paper, we consider a multiserver queuing system in which additional servers are allowed for a longer queue to reduce the customer’s balking and reneging behavior. The customers are assumed to arrive in Poisson ...

$(m,n)$algebraically compactness and $(m,n)$pure injectivity
(Springer and the Iranian Mathematical Society (IMS), 20140401)In this paper, we introduce the notion of $(m,n)$algebraically compact modules as an analogue of algebraically compact modules and then we show that $(m,n)$algebraically compactness and $(m,n)$pure injectivity for modules ...

$(m,n)$Hyperideals in Ordered Semihypergroups
(Shahid Beheshti University, 20200101)In this paper, first we introduce the notions of an $(m,n)$hyperideal and a generalized $(m,n)$hyperideal in an ordered semihypergroup, and then, some properties of these hyperideals are studied. Thereafter, we characterize ...

MFUZZIFYING DERIVED OPERATORS AND DIFFERENCE DERIVED OPERATORS
(University of Sistan and Baluchestan, 20100601)This paper presents characterizations of Mfuzzifying matroids bymeans of two kinds of fuzzy operators, called Mfuzzifying derived operatorsand Mfuzzifying difference derived operators.

MFUZZIFYING INTERVAL SPACES
(University of Sistan and Baluchestan, 20170201)In this paper, we introduce the notion of $M$fuzzifying interval spaces, and discuss the relationship between $M$fuzzifying interval spaces and $M$fuzzifying convex structures.It is proved that the category {bf MYCSA2} ...

MFUZZIFYING MATROIDS INDUCED BY MFUZZIFYING CLOSURE OPERATORS
(University of Sistan and Baluchestan, 20170601)In this paper, the notion of closure operators of matroids is generalized to fuzzy setting which is called $M$fuzzifying closure operators, and some properties of $M$fuzzifying closure operators are discussed. The ...

MFUZZIFYING TOPOLOGICAL CONVEX SPACES
(University of Sistan and Baluchestan, 20181201)The main purpose of this paper is to introduce the compatibility of $M$fuzzifying topologies and $M$fuzzifying convexities, define an $M$fuzzifying topological convex space, and give a method to generate an $M$fuzzifying ...

MGuard Stent in Stemi Patients with High Thrombus Burden Lesions: A Prospective, Single Arm Study
(Mashhad University of Medical Sciences, 20140401)Introduction: Primary PCI is the preferred modality to restore blood perfusion in STEMI patients, but myocardial reperfusion is sometimes lower than optimal. Distal embolization seems to play the leading role. There is ...

MIDEAL STRUCTURE IN UNIFORM ALGEBRAS
(University of Tehran, 19900301)It is proved that if A is aregular uniform algebra on a compact Hausdorffspace X in which every closed ideal is an Mideal, then A = C(X).

mpolar intuitionistic graphs and its properties
(Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 20180101)In many real world problems, data sometimes comes from n agents (n≥2), multipolar information exists. For issues that are associated with uncertainty, this information can not be showed with the values of crisp, fuzzy, ...

Mpolynomial and degreebased topological indices
(University of Kashan, 20151001)Let $G$ be a graph and let $m_{ij}(G)$, $i,jge 1$, be the number of edges $uv$ of $G$ such that ${d_v(G), d_u(G)} = {i,j}$. The {em $M$polynomial} of $G$ is introduced with $displaystyle{M(G;x,y) = sum_{ile j} m_{ij}(G)x^iy^j}$. ...

Mpolynomial of some graph operations and Cycle related graphs
(University of Kashan, 20190701)In this paper, we obtain Mpolynomial of some graph operations and cy cle related graphs. As an application, we compute Mpolynomial of some nanostruc tures viz., TUC4C8[p; q] nanotube, TUC4C8[p; q] nanotorus, line graph ...
