In this paper we investigate the dynamic multi cast routing problem for single rate loss networks and brie y discuss the dynamic multicast rout ing algorithm called Least Load Multicast Rout ing LLMR We propose a new multicast routing algorithm called Maximum Mean Number of New Calls Accepted Before Blocking Multicast Routing MCBMR which can more accurately re ect the current and future loading...

we consider an m/g/1 queue with regular and optional phase vacation and withstate dependent arrival rate. the vacation policy is after completion of service if there are no customers in the system, the server takes vacation consisting of k -phases, each phase is generally distributed. here the first phase is compulsory where as the other phases are optional. for this model the supplementary var...

this paper investigates an epq model with the increasing demand and demand dependent production rate involving the trade credit financing policy, which is seldom reported in the literatures. the model considers the manufacturer was offered by the supplier a delayed payment time. it is assumed that the demand is a linear increasing function of the time and the production rate is proportional to ...

the influence of mo particle size on the catalytic activity and product selectivity of alkalized mos2 nanocatalysts has been investigated. nanocatalysts are prepared using a microemulsion technique with water-to-surfactant ratios of 1-12. three different techniques, including xrd, tem, and hydrogen chemisorption were used to determine the molybdenum average particle size and their activity and ...

introduction: despite extensive studies about effects of crataegus monogyna on cardiovascular diseases yet, a few study has been undertaken antiarrhythmic property of this plant. aims of the present study were: 1) to determine the protective role of methanolic extract of c.monogyna on the rate-dependent model and the concealed conduction . 2) to explore the role of na+-k+ a tpase in the protect...

a new mathematical model for the optimal production isformulated for the inventory management system under time-varyingand stochastic inflation environment for deteriorating items. the timehorizon is finite and demand rate is dependent to the inflation. in thereal situation, some but not all customers will wait for backlogged itemsduring a shortage period, such as for fashionable commodities or...
