This paper presents a multi-objective mixed-integer non-linear programming model for congested multiple-server discrete facility location problem with uniformly distributed demands along the network edges. Regarding capacity of each and maximum waiting time threshold, developed aims to determine number locations established facilities their corresponding assigned servers such that traveling dis...

The EPRCA (Enhanced Proportional Rate Control Algorithm) is a leading congestion control protocol for Available Bit Rate (ABR) service in ATM networks. Even though the EPRCA has been adopted by the ATM forum as the standard for ABR congestion control, we show that this protocol is only marginally stable. The stability analysis presented in this paper does not consider interactions among network...

Severe hemorrhagic enterocolitis was observed in a Siberian tiger (Panthera tigris altaica) and a lion (Panthera leo). Both animals developed acute depression, anorexia, and bloody diarrhea several days before death. Small and large intestines were diffusely congested, edematous, necrotic, and filled with hemorrhagic fluid, and mesenteric lymph nodes were enlarged and congested. Pure and abunda...

Statistical mechanics of a small system of cars on a single-lane road is developed. The system is not characterized by a Hamiltonian but by a conditional probability of a velocity of a car for the given velocity and distance of the car ahead. Distribution of car velocities for various densities of a group of cars are derived as well as probabilities of density fluctuations of the group for diff...

The Optimised Link State Routing (OLSR) is a proactive routing protocol which relies on periodical broadcast of routing packets. However, due to the one-to-many relationship of broadcast traffic, the delivery of these packets can not be guaranteed by underlying MAC protocol, particularly in a congested condition. In this paper, the possible routing pathologies and failures of OLSR in a congeste...

In this thesis, an efficient traffic flow admission control mechanism supporting DiffServ is proposed to provide QoS in MPLS networks. We propose a dynamic and flexible flow admission control for MPLS support of DiffServ to prevent the waste of resources. Ingress LSRs may collect information to find out the congested area using control messages exchanged in QoS routing. We exclude the congested...

We consider the informational role of a queue when a firm can adjust its price to signal its quality to uninformed consumers. When the proportion of informed consumers is relatively high, increasing the price of a high-quality good is a superior signaling strategy. In this case, highand low-quality firms choose different prices, so the queue has no role in communicating information about qualit...
