This letter presents a near–far resistant detection scheme for asynchronous code-division multiple access with frequency offset. Based on a one-shot technique and Taylor expansion, a zeroth-order and a first-order one-shot linear decorreating detector (LDD) are proposed. The zeroth-order LDD has simple architecture but suffers performance degradation for large frequency offset. The first-order ...

Shot peening has been developed to enhance the fatigue strength of metallic parts. However, improper shot peening can decrease the fatigue life due to induced high surface roughness and residual tensile stress. The effectiveness of the manual shot peening process is accomplished by the control of the process parameters to provide a uniform intensity and coverage throughout the work piece. This ...

The study aimed to establish the modalities of the rotational shot put technique of two elite shot putters with substantially different constitutional characteristics. A biomechanical analysis of the technique was carried out using the APAS 3-D kinematic system, whereby a 15-segment model of shot putters was defined by 18 reference points. To enable the calculation of the kinematic and dynamic ...

We study a class of non-stationary shot noise processes which have a general arrival process of noises with non-stationary arrival rate and a general shot shape function. Given the arrival times, the shot noises are conditionally independent and each shot noise has a general (multivariate) cumulative distribution function (c.d.f.) depending on its arrival time. We prove a functional weak law of...

For structured-light range imaging, color stripes can be used for increasing the number of distinguishable light patterns compared to binary BW stripes. Therefore, an appropriate use of color patterns can reduce the number of light projections and range imaging is achievable in single video frame or in “one shot”. On the other hand, the reliability and range resolution attainable from color str...

In this short paper, a novel approach that combines global and local information to detect abrupt and gradual shot changes is proposed. In this approach, abrupt shot change is detected by an adaptive threshold computed from DC frame histogram difference with a sliding window. To detect gradual shot changes, this work performs an analysis of blockwise histogram difference with a statistical mode...

This paper describes the contribution of the TZI to the shot detection task of the TREC 2003 video analysis track (TRECVID). The approach comprises a feature extraction step and a shot detection step. In the feature extraction, three features are extracted: a frequency-domain approach based on FFT-features, a spatial-domain approach based on changes in the image luminance values, and another sp...

KDDI R&D Laboratories has been participating in the past TREC conferences for text retrieval tasks. In this year we are newly participating Video Retrieval Evaluation at TREC 2003, shot boundary determination task and story segmentation task. The report on our story segmentation task will be presented on site. In shot boundary determination task, we applied our proprietary shot segmentation alg...

PURPOSE Although muscle mass and strength are thought to be closely related to throwing performance, there are few scientific data about these parameters in elite shot-putters. The purpose of this case report was to present longitudinal data for muscle strength and body composition in relation to performance of an elite male shot-putter. METHODS A male national champion with the best rotation...
