Highly Efficient Multichannel Spin-Polarization Detection

Physical Review Letters, 2011
Since the original work by Mott, the low efficiency of electron spin polarimeters, remaining orders of magnitude behind optical polarimeters, has prohibited many fundamental experiments. Here we report a solution to this problem using a novel concept of multichannel spin-polarization analysis that provides a stunning increase in efficiency by 4 orders ...

Efficient human face detection in infancy

Developmental Psychobiology, 2015
ABSTRACTAdults detect conspecific faces more efficiently than heterospecific faces; however, the development of this own‐species bias (OSB) remains unexplored. We tested whether 6‐ and 11‐month‐olds exhibit OSB in their attention to human and animal faces in complex visual displays with high perceptual load (25 images competing for attention). Infants (

Efficient Cluster Detection by Ordered Neighborhoods

2015
Detecting cluster structures seems to be a simple task, i.e. separating similar from dissimilar objects. However, given today’s complex data, (dis-)similarity measures and traditional clustering algorithms are not reliable in separating clusters from each other.

Energy efficient TH-UWB preamble detection

2009 IEEE International Conference on Ultra-Wideband, 2009
This paper presents an energy efficient way to detect a UWB Impulse Radio (UWB-IR) signal relying on a Time Hopping sequence with a non coherent receiver. This detection is performed in a periodic manner, observing the received signal on the mean pulse repetition period basis.

Efficient and effective Web change detection

Data & Knowledge Engineering, 2003
In this paper we present a new technique for detecting changes in Web documents. The technique is based on a new method to measure the similarity of two documents, that represent the actual and the previous version of the monitored page. The technique has been effectively used to discover changes in selected portions of the original document.

Efficient Photon Number Detection

1990
Photon number detection, a crucial component of many optical and precision measurement systems, is currently limited by the tradeoff between detector quantum efficiency η and power gain G for noise suppression. Large gain photomultiplier tubes have relatively small η (typically ≤ 0.3), while high η photodiodes have little or no gain.

Detection efficiency of coherent optical radar

Applied Optics, 1984
Using the Huygens-Fresnel principle, the detection efficiency of a coherent optical radar is formulated. This formulation includes the effect of misalignment between the signal field and the local oscillator field. In the far-field case, the detection efficiency of a diffuse target is approximately half that of a glint target when the transmitter and ...

Efficient remote homology detection

2010
We propose an effcient multi-class classiffcation algorithm for remote homology detection (RHD). Unlike methods that treat RHD as a set of binary classiffcation tasks, our algorithm solves a single multiclass classiffcation problem by incorporating information about classwise correlations among the proteins using joint kernel functions. Furthermore,the
