BIOMIXING BY CHEMOTAXIS AND EFFICIENCY OF BIOLOGICAL REACTIONS:THE CRITICAL REACTION CASE
CHEMOTAXIS EFFICIENCY BIOLOGICAL REACTIONS CRITICAL REACTION CASE
2015/7/14
Many phenomena in biology involve both reactions and chemotaxis. These processes can clearly influence each other, and chemotaxis can play an important role in sustaining and speeding up the reaction....
Efficiency of inhomogeneous thermoelectric generators
Inhomogeneous thermoelectrics Domenicali’s equation
2010/9/20
We revisit the classical problem of the efficiency of inhomogeneous thermoelectric generators. The effects of different physical parameters on the efficiency of a generator are studied by solving the ...
A new approach to estimate the mix efficiency in data envelopment analysis
Data Envelopment Analysis Mix efficiency
2010/9/26
Recently, in Data Envelopment Analysis (DEA) methodology, there are two type of efficiency measurement; radial and non-radial measure represented by the Charnes-Cooper-Rhodes (CCR) and the slack-based...
A satisficing game theory approach for efficiency evaluation with interval data
Production systems Satisficing game theory DEA Performance analysis
2010/9/25
In this study we consider the problem of analyzing the performance of a decision making unit in to two directions: at first stage, we consider resource utilization versus output performance and at sec...
A combined interval net DEA and BSC for evaluating organizational efficiency
