let g=(v,e) be a graph with vertex set v and edge set e.for two vertices u,v of g ,the closed interval i[u,v] ,consists of u,v and all vertices lying in some u-v geodesic in g.if s is a set of vertices of g then i[s]is the union of all sets i[u,v]for u,v ? s. if i[s]=v(g) , then s is a geodetic set for g.the geodetic number g(g) is the minimum cardinality of geodetic set.the maximum cardinalit...
Background: Hitchhiking is a well-known form of transportation, which has been extensively studied from a sociological perspective. While this tourism approach has been popular in some countries for decades, the question of making hitchhiking fast has never been studied from a comprehensive point of view. In this research, we aim to find the best locations for hitchhiking, which may be used in ...
in this paper we introduced a new priority rule algorithm in human queues. the suggested method is applicable in human lines with different demands (serving times) for different customers. in this method, the waiting time for each customer is related to the volume of demand. a common example of such a system is a bakery line. the usual priority rule algorithm in this kind of queue is first-in-f...
from its emergence till present time marxist principles has undergone great changes since their promulgation by marx. many theorists and thinkers set at rectifying marxist tenets and introducing those of their own while others advocated its main concepts and attempted at improving them. among marxist philosophers who had an intensive study of marxs ideology, is louis althusser whose reflections...
chapter one is devotod to collect some notion and background informations, which are needed in the next chapters. it also contains some important statements which will be proved in a more general context later in this thesis. in chapter two, we show that if the marginal factor-group is of order np1...pk,n>1, then we obtain a bound for the order of the verbal subgroup. also a bound for the bear-...
A simple, time effective and cost effective, methos was reported for synthesis of nickel oxide nanostructure. The NiO nanostructure was synthesized by gamma-irradiation method from NiSO4 precursor. The solution was irradiated by 60Co gamma-ray source at the dose rate of 40 Gy/min for determined time. The synthesized powders are characterized by means of X-ray powder diffraction (XRD), Energy-di...
An Automated Storage and Retrieval System (AS/RS) operates a shuttle with computer process control to execute the storage and retrieval of warehouse stock. It can be equipped with the traditional single shuttle or the newly developed twin shuttle. There has been a significant literature on the comparison of single shuttle systems versus twin shuttle systems. Researchers agree that twin shuttle ...
