In an earlier paper the notion of a ray guard, a guard that can only see along a single ray, was introduced. Ray guarding means siting the fewest possible guards that guard all adjacencies (shared edges or parts of edges) in an orthogonal arrangement of adjacent nonoverlapping rectangles. In the earlier paper the problem was restricted by requiring that the direction of sight be parallel to one...

This report contains two parts: (1) A list of “points” highlighting the strategic-political and military-technical reasons and implications of the very probable siting of ITER (the International Thermonuclear Experimental Reactor) in Japan, which should be confirmed sometimes in early 2004. (2) A technical analysis of the nuclear weapons proliferation implications of inertialand magnetic-confin...

Abstract The required acceleration of onshore wind deployment requires the consideration both economic and social criteria. With a spatially explicit analysis validated European turbine stock, we show that historical siting focused on cost-effectiveness turbines minimization local disamenities, resulting in substantial regional inequalities. A multi-criteria allocation approach demonstrates 180...
