For the most part, district heating demands can be met by an appropriate integration of cogeneration and heat pumps units provided that advantage is taken of the fact that many urban regions are concentrated around surface waters. Such an integration resul ...
We report thermally stable latched operation of a nonlinear Fabry-Perot device without heat sinking other than through the 0.5-mm GaAs substrate. The device has a 2-μm GaAs spacer and integrated dielectric mirrors with reflectivities of 91% and 99%. Operat ...
The main feature of a bilateral Master-Slave servomanipulator is its "transparency", i.e. the operatr has virtually to feel as if his own hands were extended to the Slave on the spot of remote operation, i.e. inside a radioactive environment. To obtain thi ...
With the push for greater energy conservation, the need for heating and/or power production is being filled by cogeneration facilities. Thus, the search for the best performance at the least cost for such multipurpose plants is made much more difficult by ...
Annealing in excess arsenic vapor at 650-degrees-C introduces thermal conversion of n-type Si-doped GaAs samples (n = 1.3 X 10(18) cm-3) into p type. The observations are made by current-voltage and electron-beam induced current measurements. The donor con ...
Traditional tools in the domains of thermal design and control of building systems usually rely on a deterministic approach. Building systems, on the other hand, are strongly influenced by meteorological variables, which obviousy are characterized by a sto ...
Using control theory, apredictive thermal regulation of the "certainty equivalence" type has been developped. Stochastic models of hourly solar rediation and outdoor air temperature, based on the theory of Markov and ARMA processes, were set up for this pu ...
Pinch analysis is a powerful analysis and design methodology for the integration of thermal processes. Although originally developed for and applied to continuous industrial processes, pinch analysis can be equally beneficial when applied to buildings. In ...
Production of electricity from solar energy is mainly achieved by means of solar cells or by central receiver power plants. These plants are driven by vapor turbines where the fluid temperature is about l000°F or by gas turbines in which gas temperature ex ...
The design and operation of building energy systems (BES) has become a subject of great interest, given the latest energy policies adapted around the world, namely increasing the energy efficiency and the share of renewable energy sources (RES) while reduc ...
