We investigate the impact of heterogeneity in the amount of incoming traffic routed by dispatchers in a non-cooperative load balancing game. For a fixed amount of total incoming traffic, we give sufficient conditions on the cost function under which the worst-case social cost occurs when each dispatcher routes the same amount of traffic, that is, the game is symmetric. We then analyze the symme...

We present novel results that relate energy and information transfer with sensitivity to initial conditions in chaotic multi-dimensional Hamiltonian systems. We show the relation among Kolmogorov-Sinai entropy, Lyapunov exponents, and upper bounds for the Mutual Information Rate calculated in the Hamiltonian phase space and on bi-dimensional subspaces. Our main result is that the net amount of ...

Background: Nutrition education and introduction of procedures for choosing healthier food have an important role to reduce the rate of non-communicable diseases. It was shown the amount of risk factors of non-communicable diseases such as energy, salt, sugar, fat and trans fatty acid on the traffic light of food labelling. The status of risk is presented through three colors of red, yellow and...

In recent decades, urban planning has tended to humanist urbanism. In this regard foot travels and bicycle use are the two strategies that urban planners and transportation engineers are using them as adequate alternatives for making cities more people friendly. Using bicycle is known as a strategy that has a great role in decreasing traffic among developing countries in recent decades. These c...

Researches using existing statistics and data collected from the area of study help officials at decision-making, to improve the region's problems, like the problem of the high rate of accidents in the region, despite the low volume of daily service. The uses of roundabouts in many parts of the world have many advantages over intersections, amongst them are increased safety and capacity and red...

This paper examines the effect of background traffic on the performance of existing high-speed TCP variant protocols, namely BIC-TCP, CUBIC, FAST, HSTCP, H-TCP and Scalable TCP. We demonstrate that the stability, link utilization, convergence speed and fairness of the protocols are clearly affected by the variability of flow sizes and round-trip times (RTTs), and the amount of background flows ...

in forest harvesting, there is an ongoing trend to increase constantly the size, power and load of logging machines. this may cause soil degradation in forest ecosystems as the passes of these machines modify important soil structural characteristics. the present study was conducted to examine impact of skidding traffic, trail slope, traffic frequency, and soil depth on bulk density and soil co...

Peer-to-peer (P2P) applications generate a huge amount of traffic. We believe that caching of P2P traffic is a promising approach to mitigate the negative effects of P2P traffic. We have designed and implemented a proxy cache for P2P traffic, which we call pCache. pCache transparently intercepts and serves traffic from different P2P systems, while not affecting other Internet applications.
