In wireless sensor networks, self-healing key-distribution schemes are used to ensure that, even if the message packets that are broadcast in some sessions get lost, the group nodes can still recover the lost session keys simply by using their personal secret keys and broadcast messages that have been received without requesting additional transmissions from the group manager. These schemes red...

I study the conversion of 13,000 miles of railroad track in the U.S. South to standard gauge on May 31 and June 1, 1886 as a large-scale natural experiment in compatibility. Using route-level freight traffic data, I find a large redistribution of traffic from steamships to railroads that declines with distance, with no effect on prices or aggregate shipments due to carriers’ anticompetitive con...

In modern day automobile traffic the problem of traffic congestion calls for the design of efficient control strategies. In this paper it is argued that in order to have efficient and systematic solutions to a traffic control problem at an intersection, graph theoretic models of the problem are quite appropriate for its exploitation. Connectivity of compatibility graph of a traffic intersection...

We revisit the problem of incentive-compatible interdomain routing, examining the quite realistic special case in which the utilities of autonomous systems (ASes) are linear functions of the traffic in the incident links and the traffic leaving each AS. We show that incentive-compatibility toward maximizing total welfare is achievable efficiently, and in the uncapacitated case, by an algorithm ...

The compatibility problems of the mini car in car-tocar frontal collision and car-pedestrian accident are discussed using accident data and computer simulations. In our analysis of the accident data in Japan, the number of fatalities was investigated using the vehicle masses and classes. It was found that the cars with identical mass are most compatible since the injuries per accident are minim...

the lane change maneuver is among the most popular driving behaviors. it is also the basic element of important maneuvers like overtaking maneuver. therefore, it is chosen as the focus of this study and novel multi-input multi-output adaptive neuro-fuzzy inference system models (manfis) are proposed for this behavior. these models are able to simulate and predict the future behavior of a driver...

The National Highway Traffic Safety Administration (NHTSA) is conducting a research program to investigate the crash compatibility of passenger cars, light trucks and vans (LTV’s) in vehicle-to-vehicle collisions. NHTSA has conducted a series of eight full-scale vehicle-to-vehicle crash tests to evaluate vehicle compatibility issues. Tests were conducted using four bullet vehicles representing ...

This paper studies the characteristics and behavior of AntNet routing algorithm and introduces two complementary strategies to improve its adaptability and robustness particularly under unpredicted traffic conditions such as network failure or sudden burst of network traffic. Both of the proposed strategies use the knowledge of backward ants with undesirable trip times called Dead Ants to balan...
