This paper represents a technique for finding optimal paths with multiple indexes in a graph. Up to the present time, all optimal paths have been determined upon one index, say, distance for which an evaluation method exists. In this paper firstly we define multiple indexes for each edge in such a way that anyone can treat the factor for assigning an optimal path. Here, we use Data Envelopment ...

western parts of the chaharmahal and bakhtiyari province (ardal county) due to containing high mountains, deep valleys and small intermountain plains as well as the placement in the path of the nomads have long been of interest to humans. the nomadic communities of the mountainous regions of chaharmahal va bakhtiyari culturally interacted with the lowland areas of fars and khuzestan's plai...

In temporal networks, where nodes interact via sequences of temporary events, information or resources can only flow through paths that follow the time ordering of events. Such temporal paths play a crucial role in dynamic processes. However, since networks have so far been usually considered static or quasistatic, the properties of temporal paths are not yet well understood. Building on a defi...

In this paper, we consider a highly recursive interconnection network known as the fully connected cubic network (FCCN). By exploiting its recursive properties, we thoroughly analyze the performance of a simple routing algorithm for the FCCN. We show that at least 800 of the routes obtained from this simple algorithm are shortest paths, and this percentage increases further with the network siz...

abstract fars province with a share of more than 16 percent holds the highest rank in producing tomato in iran. this study aims at determining priorities for tomato processing centers in fars province’s townships. to achieve the study objective a distance minimizing pattern was used for transportation network between producing and processing centers as well as processing and consumption centers...

The enzymes of the family of tRNA synthetases perform their functions with high precision by synchronously recognizing the anticodon region and the aminoacylation region, which are separated by approximately 70 A in space. This precision in function is brought about by establishing good communication paths between the two regions. We have modeled the structure of the complex consisting of Esche...

of a thesis at the University of Miami. Thesis supervised by Associate Professor Dilip Sarkar. No. of pages in text. (37) A GPS system selects routes between two points with minimum physical distance or minimum driving time. Here we address a different type of route selection problem. Given a road map with driving distance and wireless connectivity for each road segment, find a driving route th...
