OASYS 2.0 (“Opinion Analysis System”) is a system developed primarly at the University of Maryland in collaboration with the University of Naples, Italy. OASYS 2.0 contains significantly extended and improved versions of algorithms in [1] that allows users to identify the intensity of opinion on a -1 to +1 scale on any topic of interest to the user. OASYS allows the user to view how that intens...

Snake-like robots have the ability of automatically performing various tasks that require man-equivalent capabilities by reaching areas difficult or impossible to reach for human beings. However, problems in path planning and design of such robots prevent them from being fully functional. In this paper, a path planning algorithm for snakelike robots is presented. Snake-like robots are modeled w...

One of the main features of High Throughput Computing systems is the availability of high power processing resources. Cloud Computing systems can offer these features through concepts like Pay-Per-Use and Quality of Service (QoS) over the Internet. Many applications in Cloud computing are represented by workflows. Quality of Service is one of the most important challenges in the context of sche...

We propose a new convex optimization formulation for the Fisher market problem with linear utilities. Like the Eisenberg-Gale formulation, the set of feasible points is a polyhedral convex set while the cost function is non-linear; however, unlike that, the optimum is always attained at a vertex of this polytope. The convex cost function depends only on the initial endowments of the buyers. Thi...

In this paper, a new approach to risk minimizing vehicle routing and scheduling problem is presented. Forwarding agents or companies have two main concerns for the collection of high-risk commodities like cash or valuable commodities between the central depot and the customers: one; because of the high value of the commodities transported, the risk of ambush and robbery are very high. Two; the ...

To identify cracks in a structure, an inverse analysis has been performed using the static and dynamic response of structure. The accuracy is highly dependent on form objective function choice optimization method. Generally, method searching solution by gradient adopted. However, for crack problem interested this study, it known to have drawback that search strongly depends initial value settin...
