the super-efficiency-DEA model extended from C2R model.In the analysis,energy consumption,labor force and capital stock are the input indexes,while GDP is the output index.Based on an empirical analysis,it is shown that although there is significant improvement in energy efficiency during 1998 to...
Define Total Energy Consumption. or “TEC” means an assessment tool used in this specification that provides flexibility to approach the issue of energy efficiency while retaining a comparable metric to assess performance. In this specification, efficie
We used DEA (Data Envelopment Analysis) SBM Bad output model, incorporating multiple inputs and two kinds of multiple outputs: desirable and undesirable as the result of input utilization. Undesirable outputs are an anomaly, which should not be ignored when measuring total-factor energy efficiency....
Energy window optimization of NECR for 89Zr imaging shows that a ULD setting near 585 keV is optimal. Full size image Acknowledgements Research reported in this publication was supported by the U.S. National Institutes of Health under grant R01-CA113941, by the National Center for Advancing...
In this paper some properties of the total energy moments of potential systems, subjected to external white noise processes, are shown. Potential systems with a polynomial form of energy-dependent damping have been considered. It is shown that the analytical relations between the statistical moments ...
6.2) in the presence of harmonic distortion of nonlinear devices such as solid-state or switched power supplies, variable-speed AC drives, and DC drives. Harmonic distortion essentially converts a portion of the useful energy into high-frequency energy that is no longer useful to most devices ...
to flight path and speed control commands, and an elevator command is computed based on the energy distribution error relative to the same flight path and speed control commands, an improvement is provided including an elevator control command in response to a column control input by the pilot. ...
