Nowadays, many dynamic problems can be efficiently modelled as Constraint Satisfaction Problems (CSPs). These constraints may be on-line non-binary constraints that traditional CSP solver can not manage directly. It is well known that any non-binary CSP can be transformed into an equivalent binary one, using some of the current techniques. However, this transformation may not be practical in pr...

some areas of ramsar, a city in northern iran are among the world’s wellknown inhabited areas with highest levels of natural radiation. annual exposure levels in these areas are up to 260 mgy y‐1 and the mean exposure rate is about 10 mgy y‐1 for a population of about 2000 residents. if elevated levels of natural radiation as high as a few hundred msv per year is detrimental to health and leads...

The Electric Power Research Institute conducted a study of Tidal In-Stream Power Production that is one of the best references available and has reports for download. A similar study of River Turbines describes many turbines. The U.S. Department of Energy’s Marine and Hydrokinetic Technology Database provides up-to-date information on marine and hydrokinetic renewable energy, both in the U.S. a...
