Lieu et al. have recently claimed that it is possible to substantially improve the sensitivity of radio-astronomical observations. In essence, their proposal is to make use of the intensity of the photon shot noise as a measure of the photon arrival rate. Lieu et al. provide a detailed quantum-mechanical calculation of a proposed measurement scheme that uses two detectors and conclude that this...

Flying Triangulation sensors enable a free-hand and motion-robust 3D data acquisition of complex shaped objects. The measurement principle is based on a multi-line light-sectioning approach and uses sophisticated algorithms for real-time registration (S. Ettl et al., Appl. Opt. 51 (2012) 281-289). As"single-shot principle", light sectioning enables the option to get surface data from one single...

This paper addresses the challenge of bridging the semantic gap that exists between the simplicity of features that can be currently computed in automated content indexing systems and the richness of semantics in user queries posed for media search and retrieval. It proposes a unique computational approach to extraction of expressive elements of motion pictures for deriving high-level semantics...

This study looked at the coordination patterns of four participants performing three different basketball shots from different distances. The shots selected were the threepoint shot, the free throw shot and the hook shot; the latter was included to encourage a phase transition between shots. We hypothesised lower variability between the threepoint and free throw shots compared to the hook shot....

MR. D., aged 48 years, saw me four months after a severe injury to both of his orbits. The injury was self-inflicted in a fit of unsound mind, probably the outcome of a motor car accident in which he was involved. It was caused by a revolver which, it is alleged, he fired after placing its muzzle on his right temple. The shot went 'in a straight line through both the orbits and emerged out of h...

We report the use of a tunable ArF laser at 193.26 nm to record simultaneous single-laser-shot, planar images of molecular hydrogen and hot oxygen in a turbulent H(2)-air diffusion flame. Excitation spectra of fuel and oxidantrich flame zones confirm a partial overlap of the two-photon H(2) (6,0) Q(1) E, F ? X and single-photon O(2) (10,2) R(17) B ? X (Schumann-Runge) absorption bands. UV Rayle...

The longitudinal profiles of ultrashort relativistic electron bunches at the soft x-ray free-electron laser FLASH have been investigated using two single-shot detection schemes: an electro-optic (EO) detector measuring the Coulomb field of the bunch and a radio-frequency structure transforming the charge distribution into a transverse streak. A comparison permits an absolute calibration of the ...

Abstract Zero-shot sketch-based image retrieval (ZS-SBIR) is a challenging task that involves searching natural images related to given hand-drawn sketch under the zero-shot scene. The previous approach projected and features into low-dimensional common space for retrieval, used semantic transfer knowledge of seen unseen classes. However, it not effective enough align multimodal when projecting...

We present a reduced-phase triple-illumination interferometer (RPTII) as a novel single-shot technique to increase the precision of dual-illumination optical phase unwrapping techniques. The technique employs two measurement ranges to record both low-precision unwrapped and high-precision wrapped phases. To unwrap the high-precision phase, a hierarchical optical phase unwrapping algorithm is us...
