Maximum power transfer versus efficiency
2016 IEEE International Symposium on Antennas and Propagation (APSURSI), 2016In electrical engineering, we obtain maximum average power from a source with some internal impedance when the connected load impedance equals the complex conjugate of the internal source impedance. This is known by the maximum power transfer theorem. Applying this theorem means that the best we can do is to distribute the source power equally between ...

Extending Oblivious Transfer Efficiently
2015On top of the passively secure extension protocol of [IKNP03] we build a new construction secure against active adversaries. We can replace the invocation of the hash function that is used to check the receiver is well-behaved with the XOR of bit strings.

Charge‐Transfer Efficiency of WFPC2
Publications of the Astronomical Society of the Pacific, 1999ABSTRACT Observations of ω Centauri have been used to characterize the charge‐transfer efficiency (CTE) of the Wide Field and Planetary Camera 2 (WFPC2) on board the Hubble Space Telescope. A set of formulae has been developed to correct aperture photometry for CTE loss with dependencies on the X‐ and Y‐positions, the background counts, the brightness ...

Efficiency and Innovation in Transfer
2000The transfer literature includes a variety of seemingly conflicting perspectives. Some argue that transfer is rare; others argue that transfer is ubiquitous; still others worry that transfer is an unworkable concept. Is the transfer literature filled with inherently contradictory claims, or is there a framework that can help illuminate how and why the ...

Efficient Estimation of Information Transfer
2014Any measure of interdependence can lose much of its appeal due to a poor choice of its numerical estimator. Information theoretic functionals are particularly sensitive to this problem, especially when applied to noisy signals of only a few thousand data points or less.

A comment on transfer efficiencies
Fisheries Oceanography, 1995ABSTRACTThis paper discusses the validity of several assumptions in a recent publication on the primary production required to sustain the annual world fish catch of £120 million t. A transfer efficiency between trophic levels in aquatic ecosymms of 15% results in the primary production requirement of 2.6% of the total primary production to sustain the
