The growing costs of fuel and operation of power generating units warrant improvement of optimization methodologies for economic dispatch (ED) problems. The practical ED problems have non-convex objective functions with equality and inequality constraints that make it much harder to find the global optimum using any mathematical algorithms. Modern optimization algorithms are often meta-heuristi...

The new EU-regulations on organic farming (1804/1999) are also influencing the animal welfare. A lot of positive regulations is to find, but also regulations that seen to mind more about the general public and customer and their view on organic farming, than the health and welfare of the animals. The paper specially focus on the impact of the regulations and the recommendations that phytotherap...

Why do speakers produce gestures? !is study tests the hypothesis that gesture facilitates the conceptual planning of speaking, and in particular, gesture promotes thinking about perceptually present information. !is view implies that, when gesture is prohibited, people should be less likely to speak about such information. We tested this prediction among children (N = 50) who solved and explain...

Underground mines are a special type of environment which requires significant attention since they directly relate to miners‟ productivity, health and safety. With coal or ore exploitation into deep underground mine environments, high temperature and humidity creates risks because of large amounts of heat generated from geothermal heat, mining machines, groundwater and mine water. There have b...

Covert food stealing is common among individuals with Prader-Willi syndrome. We found that verbal reprimands, delivered contingent upon eating prohibited foods, were sufficient to decrease the food stealing of a girl with Prader-Willi syndrome. Warning stimuli were then used to help her discriminate between permitted and prohibited foods during sessions in which food stealing was not directly o...

In this paper, a stochastic multiobjective framework is proposed for a day-ahead short-term Hydro Thermal Self-Scheduling (HTSS) problem for joint energy and reserve markets. An efficient linear formulations are introduced in this paper to deal with the nonlinearity of original problem due to the dynamic ramp rate limits, prohibited operating zones, operating services of thermal plants, multi-h...

An important criterion in power system operation is to meet an efficient approach for solving economic dispatch (ED) problems with non convex cost functions using particle swarm optimization (PSO). Although the Particle Swarm Optimization (PSO) approaches have several advantages suitable to heavily constrained non convex optimization problems, PSO framework employing chaotic sequences combined ...
