The collection of various sites, distributed over a computer network is called Distributed Database whereas the technique of finding the optimal processing method to answer a query is called Query Optimization. In Distributed Database, the sites communicate with each other through networks. There are various issues arise during evaluation of query cost, among which the processing cost and a tra...

The following minimum cost maximum multiiow problem is the focus of the paper: () given an undirected graph G = (V G; EG), a subset T 2 V G (of terminals), and functions c : EG ! ZZ + (of capacities) and a : EG ! ZZ + (of costs), nd a collection f of ows (a multiiow) connecting arbitrary pairs of distinct terminals so that the total ow f (e) through each edge does not exceed its capacity c(e), ...

Introduction: Hospital administrators have always faced the challenge of providing the best possible health services in a resource-limited environment. The patient flow throughout the hospital is affected by lack of the capacities that can lead to bed-blocking among the hospital units. In this research, the patient flow in the hospital is modeled as an open queueing network with blocking. Then,...

We address the problem of efficiently gathering correlated data from a wired or a wireless sensor network, with the aim of designing algorithms with provable optimality guarantees, and understanding how close we can get to the known theoretical lower bounds. Our proposed approach is based on finding an optimal or a near-optimal compression tree for a given sensor network: a compression tree is ...

in this paper we intend to generate some set of optimal trajectories according to the number of control points has been applied for parameterizing those using b-spline curves. the trajectories are used to generate an optimal locomotion gait in a crawling worm-like robot. due to gait design considerations it is desired to minimize the required torques in a cycle of gait. similar to caterpillars,...
