In this paper we present a multicast protocol for building and maintaining Delay-Constrained Multi-cast Shared Trees (DCMST). Our protocol is based on the search of available Delay-Constrained multi-path to graft a new receiver to the shared tree. The new receiver chooses the most promising route regarding to its available bandwidth. This improvesthe load balancing on the network and we ooer be...

We approach the problem of load balancing for wireless multi-hop networks by distributed optimisation. We implement an approximation algorithm for minimising the maximum network congestion as a modification to the DSR routing protocol. The algorithm is based on shortest-path computations that are integrated into the DSR route discovery and maintenance process. The resulting Balanced Multipath S...

Multipath routing is a technique that allows tra c dispersion and so, through the use of load-balancing, nodes energy consumption minimization or analysis for tra c prevention, it is capable to improve performance in mobile ad hoc networks. In this work we compare multipath version for two reactive protocols: DYMO and DSR. We study the impact of tra c dispersion on both UDP and TCP tra c. Moreo...

This paper examines the interactions between routing and inventory-management decisions in a two-level supply chain consisting of a cross-docking warehouse and N retailers. Retailer demand is stochastic; i.e., normally distributed and independent across retailers and over time. Travel times are fixed between pairs of system sites. Every m time periods, system inventory is replenished at the war...

In this paper by using numerical evaluation the effect of balancing drupes of water hammer on tunnels lining is considered. In case of not arrangment of these reservoirs, the tunnel lining will be damaged of cyclic powers of water hammer. In this research, function of balancing reservoir of water hammer on cover of tunnels to the barriers’ turbine is simulated by numerical methods and Plaxis 3D...

Network routing algorithms responsible for selecting paths to destinations have a profound impact on network reliability experienced by the network users. Unfortunately, performance of state-of-the-art routing algorithms often falls short of users’ expectations. (i) The flexibility with which operators of independently administered networks can choose their routing policies allows them to make ...

Assembly Line production is one of the widely used basic principles in production system. The problem of Assembly Line Balancing deals with the distribution of activities among the workstations so that there will be maximum utilization of human resources and facilities without disturbing the work sequence. Research works reported in the literature mainly deals with minimization of idle time i.e...

oral contraceptive pills have several side effects especially on the gastrointestinal tract and liver. absorption of low dose (ld) pills by the vaginal route avoids the first pass of the steroids through these tracts and probably has fewer side effects. this study was a cohort study for evaluation of side effects and acceptability of ld pills administered by the vaginal route. in a clinical tri...
