the main objective of this article is to present the result of a research on industrial distribution network in iran which for the first time is being carried out for the purpose of recognizing the industrial goods distribution network, estimation of the volume of transaction in each case, and to study the impact of certain elements. the factors and variables which their impact on the volume of...

Content Delivery Networks (CDNs) are a vital component of the Internet’s content delivery value chain, servicing nearly a third of the Internet’s most popular content sites. However, in spite of their strategic importance little is known about the optimal pricing policies or adoption drivers of CDNs. We address these questions using analytic models of the market structure for Internet content d...

The monophthongization of /ay/ in the Southern United States is disfavored by following voiceless consonants (PRICE) relative to voiced or word-final environments (PRIZE). If monophthongization is the trigger for the Southern Shift (Labov, 2010) and chain shifts operate as predicted by a modular feedforward phonological theory (cf. Bermúdez-Otero, 2007), this implies PRICE and PRIZE must be two...

In this article, a multi-objective function for placement of Distributed Generation (DG) and capacitors with thetap setting of Under Load Tap Changer (ULTC) Transformer is introduced. Most of the recent articles have paidless attention to DG, capacitor placement and ULTC effects in the distribution network simultaneously. Insimulations, a comparison between different modes was carried out with,...

water distribution method based on the type of water conduits can be divided into two groups, namely, open and closed systems, while on the basis of the energy of the water flow, the two groups are gravity flow and pressurized flow. open channel type conveyance and distribution is achieved by gravity and includes channels made by embankment construction, excavation, or construction of prefabric...

This paper deals with the fundamental problem of estimating the distribution function (df) of the duration of the longest path in the stochastic activity network such as PERT network. First a technique is introduced to reduce variance in Conditional Monte Carlo Sampling (CMCS). Second, based on this technique a new procedure is developed for CMCS. Third, a combined approach of simulation and ap...

The problem we investigate deals with the optimal assignment of resources to the activities of a stochastic project network. We seek to minimize the expected cost of the project include sum of resource utilization costs and lateness costs. We assume that the work content required by the activities follows an exponential distribution. The decision variables of the model are the allocated resourc...

Random walk is one of the basic mechanisms found in many network applications. We study the epidemic spreading dynamics driven by biased random walks on complex networks. In our epidemic model, each time infected nodes constantly spread some infected packets by biased random walks to their neighbor nodes causing the infection of the susceptible nodes that receive the packets. An infected node g...

Abstract –In our empirical works, we find that there exists the equivalency of the cumulative degree distribution and edge-cumulative distribution. Furthermore, we employ three network models of the recursive graphs, Sierpinksi networks and Apollonian networks to verify our conjecture: Both the cumulative degree distribution and the edge-cumulative distribution are equivalent to each other in d...
