Bottleneck routing games are a well-studied model to investigate the impact of selfish behavior in communication networks. In this model, each user selects a path in a network for routing their fixed demand. The disutility of a used only depends on the most congested link visited. We extend this model by allowing users to continuously vary the demand rate at which data is sent along the chosen ...

Military theater settings may involve many competing missions whose whose requirements tax the coalition’s resources in multiple dimensions—i.e., requiring different amounts of many different kinds of resources, e.g., fuel, bandwidth, personnel, etc., each of which is available in limited supply— and in uncertain or stochastic amounts. To serve the overall mission, we need to satisfy resource r...

We now know that the natural habitat around the world has been and continues to be threatened and destroyed at alarming rates, with more than 60% of terrestrial plant species now finding safe harbor on less than 1.4% of the Earth’s...

The aim of this study was to assess physiological demands of competitive basketball by measuring oxygen consumption (VO2) and other variables during practice games. Each of 12 players (20.4 +/- 1.1 years) was monitored in a 20-min practice game, which was conducted in the same way as actual games with the presence of referees and coaches.

This paper investigates the network location problem for single-server facilities that are subject to congestion. In each network edge, customers are uniformly distributed along the edge and their requests for service are assumed to be generated according to a Poisson process. A number of facilities are to be selected from a number of candidate sites and a single server is located at each facil...
