In this paper, the authors treat the key frame extraction problem from a viewpoint of shot reconstruction. As a result, a novel criterion called shot reconstruction degree (SRD) is proposed for key frame selection based on the degree of retaining motion dynamics of a video shot. Compared with the widely used fidelity criterion, the key frame set produced by SRD can better capture the detailed d...

The aim of this study is to develop a Discrete Element Model (DEM) capable of simulating the main shot peening (SP) processes of industrial interest. By means of this model, shot shot interaction, shot target interaction and the overall shot flow were investigated in detail with limited computational effort. A new technique to dynamically change the coefficient of restitution (CoR) for repeated...

This paper presents a shot cut detection technique using a combination of multiple experts. The experts themselves are stand-alone methods to detect shot cuts. We propose a combination method that gives signiic-antly better results compared to these experts on their own. We achieve this by exploiting the complementar-ity of expert knowledge, i.e. the fact that the various experts calculate diie...

Dorsal closure of the Drosophila embryonic epithelium provides an excellent model system for the in vivo analysis of molecular mechanisms regulating cytoskeletal rearrangements. In this study, we investigated the function of the Drosophila spectraplakin Short stop (Shot), a conserved cytoskeletal structural protein, during closure of the dorsal embryonic epithelium. We show that Shot is essenti...

In basketball, every time the offense produces a shot opportunity the player with the ball must decide whether the shot is worth taking. In this paper, I explore the question of when a team should shoot and when they should pass up the shot by considering a simple theoretical model of the shot selection process, in which the quality of shot opportunities generated by the offense is assumed to f...

The aim of this study was to investigate changes in shot put performance, muscular power, and neuromuscular activation of the lower extremities, between the preseason and the competition period, in skilled shot put athletes using the rotational technique. Shot put performance was assessed at the start of the pre-season period as well as after 12 weeks, at the competition period, in nine shot pu...

I present in this paper a method to subtract the bias due to source photon noise from visibilities measured with a single-mode optical interferometer. Properties of the processed noise are demonstrated and examples of subtraction on real data are presented.
