Prompted by recent discoveries of log-normal distributions in gamma-ray/X-ray temporal variabilities of gamma-ray bursts (GRBs) and blazars, we re-examine the X-ray variability of Cygnus X-1 in the hard/low state using Ginga data in 1990. It was previously reported that the distributions of the time intervals between X-ray shots (flares) deviated from the Poisson distributions at short time int...

Evaluation of NHL goalies is often done by comparing their save percentage. These save percentages depend highly upon the defense in front of each goalie and the difficulty of shots that each goalie faces. In this paper we introduce a new methodology for evaluating NHL goalies that does not depend upon the distribution of shots that any individual goalie faced. To achieve this new metric we cre...

Elbow problems in goalkeepers in team handball ‘‘handball goalie’s elbow’’ is common. The accepted mechanism in the common injuries is hyperextension of the elbow. The purpose of this study was to describe the elbow position at the time of impact of the ball on the hand. This study is based on video-analysis. Fifteen handball goalies (ten females and five males) who had been playing handball fo...

Recently, investigation into shot boundary detection schemes has gathered much momentum [20-29]. Cut detection is seemingly easily solved by an elementary statistical examination of inter-frame characteristics; however a truly accurate and generalized cut detection algorithm still eludes researchers. Reliable shot boundary detection forms the cornerstone for video segmentation applications as s...

Based upon the expertise performed by ten basketball professional relative importance coefficients with regard to positions in the game were determined for nineteen performance evaluation criteria. High degree of interobservers agreement was obtained concerning all positions (from 0.91 to 0.98). In concordance with the obtained results the particular play positions were explicitly described, as...

ABSTRACT Archerfish down a variety of aerial prey from range distances using water jets that they adjust to the size and distance their prey. We describe here characteristic rapid fin maneuvers, most notably pectoral pelvic fins, are precisely coordinated with release jet. discovered these maneuvers in two fish, which had been characterized detail, trained shoot fixed positions at targets diffe...

The massacre at Columbine High School last year unleashed a torrent of fresh concern over the threat that violence poses to society. It also energized a government research effort to understand and prevent violence. Ironically, this flurry of activity comes at a time when youth violence, as reflected in crime statistics, is in decline.

We have built a system that automatically generates camera actions for storytelling in virtual environments. Given a sequence of character actions, scene properties (like mood, tempo, etc), and a mapping from names to characters, objects, and locations in a graphical world, the goal of a camera planning system is to generate sequences of directives for the camera to satisfy derived from certain...
