UK councils face £7.5 million 'efficiency' cuts

Face Search at Scale: 80 Million Gallery

Due to the prevalence of social media websites, one challenge facing computer vision researchers is to devise methods to process and search for persons of interest among the billions of shared photos on these websites. Facebook revealed in a 2013 white paper that its users have uploaded more than 250 billion photos, and are uploading 350 million new photos each day. Due to this humongous amount...

Poor economy means poorest Americans face health care cuts.

Is subjective duration a signature of coding efficiency ? 75 76

Perceived duration is conventionally assumed to correspond with objective duration, but a growing literature suggests a more complex picture. For example, repeated stimuli appear briefer in duration than a novel stimulus of equal physical duration. We suggest that such duration illusions appear to parallel the neural phenomenon of repetition suppression, and we marshal evidence for a new hypoth...

Over 75% incident-photon-to-current efficiency without solid electrodes.

The efficiency of photoelectrochemical reactions is conventionally defined in terms of the ratio between the current responses arising from the collection of carriers at electrical contacts and the incident photon flux at a given wavelength, i.e. the incident-photon-to-current-efficiency (IPCE). IPCE values are determined by a variety of factors such as the absorption constant of the active lay...

75%-efficiency blue generation from an intracavity PPKTP frequency doubler

We report on a high-efficiency 461 nm blue light conversion from an external cavityenhanced second-harmonic generation of a 922 nm diode laser with a quasi-phasematched KTP crystal (PPKTP). By choosing a long crystal (LC = 20mm) and twice looser focusing (w0 = 43μm) than the ”optimal” one, thermal lensing effects due to the blue power absorption are minimized while still maintaining near-optima...
