Energy conservation objective analysis

Efficient use of both energy and resource in an evaporation system was studied based on multi-objective analysis. The exergy consumption and the total investment cost were used to measure energy and resource conservation, respectively. The trade-off curve between the two objectives shows the change in the optimal solution as the unit cost of exergy is changed. 

The conserved quantities that are of utmost importance to a chemical engineer are mass, energy, and momentum. It is the objective of this text to teach you how to utilize the conservation of mass in the analysis of units and processes that involve mass flow and transfer and chemical reaction. For each conserved quantity the principle is the same—conserved quantities are... 

X-ray microanalysis techniques— in particular, electron probe x-ray microanalysis (EPXMA or EPMA) and SEM coupled with energy dispersive spectrometers (EDS, EDX) are, by far, one of the surface analysis techniques most extensively used in the field of art and art conservation, and they have actually become routine methods of analyzing art and archaeological objects and monitoring conservation treatments [34, 61, 63]. 

In this paper we have drawn on analyses carried out as part of the Maya Jade and Ceramics Project, a collaborative program of the Museum of Fine Arts, Boston and Brookhaven National Laboratory during 1977-1983. Work at Brookhaven was conducted under the auspices of the U.S. Department of Energy. Exploration into the interface between archaeological objectives, compositional variation and statistical modeling is an endeavor of the Smithsonian Archaeometric Research Collections and Records (SARCAR) facility located at the Smithsonian s Conservation Analytical Laboratory. Neffs participation in this research is made possible by a Smithsonian Institution Materials Analysis Postdoctoral Fellowship. 

Solving the transport equations over domains covering more than one fuel cell element has to be done carefully. In the gas channels and in the gas diffusers, the objects of analysis are gas mixtures, whereas in the membrane, catalyst layers, and partially in the gas diffuser, it is the liquid water. The energy equation may be solved over the entire domain covering all the fuel cell elements the continuity, momentum, and species conservation equations must be solved for each domain. It should be noted that the gas diffusers and catalyst layers each belong to two different domains.
