proposing a robust designed facility location is one of the most effective ways to hedge against unexpected disruptions and failures in a transportation network system. this paper considers the combined facility location/network design problem with regard to transportation link disruptions and develops a mixed integer linear programming formulation to model it. with respect to the probability o...

in this paper, we study the multi-depot vehiclerouting problem with inter-depot routes, in which the vehicles can replenish atintermediate depots. vehicles leave the origin depot with load on-board andserve customers until out of load. they may visit an intermediate depot toreplenish and finally return to the origin depot, completing their route. weinitiate a mathematical mixed integer programm...

hub location problems are among the extensions ofclassical location problems that have numerous applications in designingtransportation, postal, and telecommunication networks. despite the evidentattention of researchers to these problems, there are few studies on designinghub networks under uncertainty and disruption. in this study, the capacitatedsingle allocation hub location problem under d...

the paper presents the semi-numerical solution for the magnetohydrodynamic (mhd) viscous flow due to a stretching sheet caused by boundary layer of an incompressible viscous flow. the governing partial differential equations of momentum equations are reduced into a nonlinear ordinary differential equation (node) by using a classical similarity transformation along with appropriate boundary cond...

This thesis describes the design, implementation and use of a software package for hypermedia based learning on mathematical sciences. The software package integrates hypertext, computer-aided exercises, graphics, videos and sound into a hypermedia based learning environment (HMLE). The design and implementation problems of hypermedia based learning environments in mathematics are presentation,...

Presenting mathematical expressions to visuallyimpaired users is a challenging task because, unlike text, a mathematical expression is bi-dimensional and has some distinguishing characteristics. At present, the state-of-the art solutions present mathematical expressions to blind users in only one presentation format and with no consideration of user’s context. In this work, we present mathemati...
