The primary source of plant parasitic nematodes in irrigation waterways in the Columbia Basin Project of eastern Washington is irrigation runoff returned into the irrigation system. This has contributed to the rapid spread of plant parasitic nematodes observed during eight years of study.

In this paper a stochastic model of tanker traffic is developed to determine the probability of vessel casualties resulting from the transit traffic through a narrow waterway. More specifically, the present study models the collision and grounding probabilities in a waterway resulting from course changes due to hydrodynamic forces acting on the vessel. The computation of vessel positions and th...

Northern Ireland is blessed with some beautiful lakeland and coastal scenery so if it's a nice day, many of us enjoy visiting areas like the Fermanagh Lakelands or North Coast. There is however a much darker side to our contact with water. In 2014, a total of 338 people drowned in the UK from accidental or natural causes. Only 14 of these deaths occurred in the open sea. 102 occurred close into...

More than 1,000 dedicated volunteers have organized what promises to be an outstanding, multidimensional program for the AAAI Conference on Artificial Intelligence (AAAI-07), and the collocated Innovative Applications of AI Conference (IAAI-07). When not ensconc ed in conference sessions, attendees can also explore Vancouver, which is nestled in the mountains, waterways and rainforests of Briti...
