Energy Conversion Efficiencies
2012Efficiency is a measure of the true effectiveness or performance of a system or a process. It may take different forms but it can generally be defined as the desired output over the required input. Energy conversion efficiency refers to an efficiency definition for a device for which one form of energy is converted to another form.

Efficient octree conversion by connectivity labeling
Proceedings of the 11th annual conference on Computer graphics and interactive techniques, 1984We present an algorithm for converting from the boundary representation of a solid to the corresponding octree model. The algorithm utilizes an efficient new connected components labeling technique. A novelty of the method is the demonstration that all processing can be performed directly on linear quad and octree encodings.

Efficient and safe-for-space closure conversion
ACM Transactions on Programming Languages and Systems, 2000Modern compilers often implement function calls (or returns) in two steps: first, a “closure” environment is properly installed to provide access for free variables in the target program fragment; second, the control is transferred to the target by a “jump with arguments (for results).” Closure conversion—which decides where and how to ...

Energy Conversion Efficiency in Nanotube Optoelectronics
Nano Letters, 2005We present theoretical performance estimates for nanotube optoelectronic devices under bias. Current-voltage characteristics of illuminated nanotube p-n junctions are calculated using a self-consistent nonequilibrium Green's function approach. Energy conversion rates reaching tens of percent are predicted for incident photon energies near the band gap ...

Perfect Photon-to-Hydrogen Conversion Efficiency
Nano Letters, 2016We report a record 100% photon-to-hydrogen production efficiency, under visible light illumination, for the photocatalytic water-splitting reduction half-reaction. This result was accomplished by utilization of nanoparticle-based photocatalysts, composed of Pt-tipped CdSe@CdS rods, with a hydroxyl anion-radical redox couple operating as a shuttle to ...

Exergy efficiency and conversion of chemical reactions
Energy Conversion and Management, 1998An exergy analysis of the ammonia oxidation in nitrous oxide has been performed using alternatively the conventional second law efficiency and the more recently proposed intrinsic exergy efficiency. It is shown that the second law efficiency does not account for the conversion effect on the overall performance of a chemical system while the intrinsic ...

Absolute oil fluorescence conversion efficiency
Applied Optics, 1976A conceptual method has been developed to deduce the characteristic infinite thickness absolute conversion efficiencies of oils from measured finite thickness film fluorescent returns. The sea water Raman signal is used as a reference in deducing the fluorescent efficiencies.

Efficient radix conversions for classes of radices
2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015Radix conversion for conventional number systems can be computed using one of the four algorithms reviewed and discussed in [1], depending on whether the source or the destination radix arithmetic is used and whether an integer or a fraction is to be converted.

Compact and efficient presentation conversion code
IEEE/ACM Transactions on Networking, 1998The inefficient presentation conversion code is a major difficulty for using a distributed-applications development environment (such as a CORBA-, Java-RMI-, DCE-, or ASN.1-based environment) to build high-speed network applications. The stub compilers included in these environments generate code that is either very slow or has a large code size.
