One of the most important factors that affects construction costs of highways is the earthwork cost. On the other hand, the earthwork cost strongly depends on the design of vertical alignment or project line. In this study, at first, the problem of vertical alignment optimization was formulated. To this end, station, elevation and vertical curve length in case of each point of vertical intersec...

We demo an online system that tracks the availability of over four-hundred public SPARQL endpoints and makes up-to-date results available to the public. Our demo currently focuses on how often an endpoint is online/offline, but we plan to extend the system to collect metrics about available meta-data descriptions, SPARQL features supported, and performance for generic queries.

This paper introduces eHumanities Desktopan online system for corpus management and analysis in support of Computing in the Humanities. Design issues and the overall architecture are described as well as an initial set of applications which are offered by the system.

We consider the problem faced by a retail chain that must select what mutual-substitute items to display in each one of its stores maximize revenues. The number cannot exceed limit space capacity store. Customers purchase product maximizes their utility, which depends on price, travel cost store, and reservation known retailer. retailer can set different price markdowns at products. considers d...

The line sum optimization problem asks for a ( 0 , 1 ) -matrix minimizing the of given functions evaluated at its row and column sums. We show that uniform problem, with identical functions, monotone over matrices nonincreasing sums, are polynomial time solvable.
