Marine pollution by oil spills is a devastating environmental hazard, requiring a low-cost efficient system for detection, real-time thickness measurement and localization of oil. Such a system is necessary to guide and speed-up the clean-up process. Knowing that none of the previous detection methods has managed to fully meet these requirements, it is(More)
Marine pollution by oil spills is a devastating environmental hazard, requiring a low-cost efficient system for continuous and real-time thickness measurement and localization of floating oil. Knowing that none of the previous detection methods has managed to fully meet these requirements, it is necessary to devise a new technique to guide and speed-up the(More)
Congestion in a transportation network is usually the result of either an increase in traffic demand, i.e. the desire of drivers to use the transportation network, or a decrease in traffic supply, i.e. the traffic capacity, which is affected by weather conditions, incidents, etc. In either case, congestion reduces the efficiency of the transportation(More)
Recently, several papers have studied the possibility of shrinking buffer sizes in Internet core routers to just a few dozen packets under certain constraints. If proven right, these results can open doors to building all-optical routers, since a major bottleneck in building such routers is the lack of large optical memories. However, reducing buffer sizes(More)
Disturbances in roadway networks due to increases in demand or drops in network capacity can severely degrade the performance of the system. The robustness of a roadway network to such disturbances has been investigated using a variety of methods leading to disparate robust network designs. This paper introduces a unifying framework for understanding and(More)
The assessment of real-time intelligent transportation system (ITS) applications, such as traffic management and adaptive route guidance systems, requires the use of fast and near real-time dynamic traffic simulation models. Even off-line applications, used for testing planning scenarios, often require fast-enough traffic simulation models that enable the(More)
