This paper presents a method based on a new interpretation of the concept productiveness in order to manage local energy resources through smart loads. The assumption that electricity demand is almost completely inelastic is changing as a result of deregulated wholesale markets. In this line,...

In the location of ambulance bases for medical assistance, an adequate time of response must be guaranteed for each area in the region covered, incurring the minimum operating costs. Several linear models (such as the maximal covering location problem, MCLP) have been developed for designing...

Free-drainage or "open" substrate system used for vegetable production in greenhouses is associated with appreciable NO3- leaching losses and drainage volumes. Simulation models of crop N uptake, N leaching, water use and drainage of crops in these systems will be useful for crop and water...
