For the Dutch smart grid demonstration project Meppelenergie, the effects of controlled thermal energy storage within the floor heating structure of a living room by a heat pump are investigated. Storage possibilities are constrained by room operative and floor temperatures. Simulations indicate limitations for floor heating storage due to absorption of solar energy within the house. To balance...

Offsetting cities’ dependence on fossil fuels is one of the key factors for meeting the environmental targets set out by the European Commission (EC) by 2020 [3]. The penetration of small-scale renewable resources in domestic households (photovoltaic panels and micro wind mills) empowers dwellings to collectively reduce their carbon footprint. Incentivizing the injection and trade of locally-pr...

Demand Response mechanisms serve to preserve the stability of the power grid by shedding the electricity load of the consumers during power shortage situations in order to match power generation to demand. Data centres have been identified as excellent candidates to participate in such mechanisms. Recently a novel supply demand agreement have been proposed to foster power adaptation collaborati...

In France, in the main media, the concern about nuclear safety and security has not really appeared before the beginning of the 1970s. The gradual changes in its perception are studied here through the arguments given in the main French news magazines, linked with several parameters. As this represents a considerable amount of copies and thus of information, are selected here the main articles ...

With the fast growth of wireless communications between nodes/sensor units, devices installed in remote places require power energy supply solutions to assure their functionally and data communication capabilities. For these applications energy harvesting takes place as a good solution, to increase the availability of energy, in opposition to the conventional systems of energy supply. Regenerat...

Satisfying true customer demand is the primary function of present day enterprises. Furthermore, this activity must be done effectively, efficiently and with appropriate responsiveness. The ultimate design and operational goal in this scenario is thus the seamless market-orientated supply chain described in detail in the paper. The research is based around 13 real-world supply chains that repre...

In this paper we proposed a modeling method of the electrode lift controlling plant of a n ultra high power electric furnace and verified the accuracy of the proposed model by simulation an d field test. Keyword: ultra high power (UHP) electric furnace, electric lift device, electric lift control

Researchers have found that the metabolisms of organisms appear to scale proportionally to a 3/4 power of their mass. Mathematics in this article suggests that the capacity of isotropic energy distribution scales up by a 4/3 power as size, and therefore the degrees of freedom of its circulatory system, increases. Cellular metabolism must scale inversely by a 3/4 power, likely to prevent the 4/3...
