l The goal of this work is to calibrate a real-time hydrodynamic model for spill tracking in the St. Clair River and to provide decision makers with information for response planning and in the event of a spill. In order to provide experimental validation data, three dye releases were carried out to simulate movement of a potential contaminant in the river. Measurements of dye concentration wer...

The amount of spill code generated by a compiler backend has crucial effects on program performance. Instruction scheduling before register allocation may cause live range overlaps that lead to suboptimal spill code. Even when a local scheduler tries to minimize register usage, its results can leave room for improvement regarding overall spill costs. We present Register Reuse Scheduling (RRS), ...

Using a team of small, sensor-rich robots and a larger, Parent robot, we have explored the problem of how to enable flexible, adjustable autonomy control for a multi-robot remote characterization task. To accomplish the task, the robot team must autonomously deploy into a building, efficiently search through corridors and rooms to locate a spill, and then cooperatively form a perimeter around a...

Oil spills near the shore is an important environmental problem. The oil spill has to be contained in early stages of accident which otherwise would spread rapidly making it hard control. gets weathered affecting marine life and can get into food chain cause ecological distress. It also affects port harbour activities. after effects are mostly irreversible, so essential follow proper control me...

The tanker Nakhodka oil spill in the Sea of Japan was happened on January 2 1997 and this accident caused serious environmental damages. After the accident, discussions and collaborations involving citizens and government have been started to make significant steps to protect natural environment of river banks, mountains and hills in the vicinity of human residents and these activities seem to ...

because of environmental sensitivity of the caspian sea, any subsea oil spills and blowouts can inflict destructive impacts on marine environment and cause catastrophic damage in the area. employing mathematical simulation is one of the easiest and most effective prediction tools for understanding the oil spill behavior under various environmental forces. in this regard, mike3d simulation packa...

Spill, used to assist the downstream passage of juvenile Chinook salmon (Oncorhynchus tshawytscha), and steelhead (O. mykiss) at eight dams in the Columbia/Snake River hydrosystem may delay the upstream passage of the adults. To evaluate the potential effects of spill on adult passage we evaluated the historical relationship between the day-to-day variations of spill and upstream fish passage a...

When customers for a product from N substitutable alternatives find their first choice sold out, they might “spill” to their second-most preferred products. The existing literature typically assumes an exogenous spill rate. We develop a surprisingly simple model that links the spill rate to economic factors associated with direct demand systems.

As oil transportation worldwide continues to increase, many communities are at risk of oil spill disasters and must anticipate and prepare for them. Factors that influence oil spill consequences are myriad and range from the biophysical to the social. We provide a summary literature review and overview framework to help communities systematically consider the factors and linkages that would inf...

Assessing the impacts of the Deepwater Horizon oil spill with a dependable baseline comparison can provide reliable insight into environmental stressors on organisms that were potentially affected by the spill. Fluctuating asymmetry (small, non-random deviations from perfect bilateral symmetry) is an informative metric sensitive to contaminants that can be used to assess environmental stress le...
