A Lagrangian numerical method based on impulse variables is analyzed. The relation between impulse vectors and vortex dipoles with a prescribed dipole moment is presented and used to adapt the high-accuracy cutoo functions of vortex methods for use in impulse-based methods. The long-time implementation of the impulse method is shown to contain a source of error whose growth in time renders impu...

Research has found an upward trend in impulse buying in general, and impulse buying is frequently foreseen among mall shoppers. Impulse purchases account for over $4 billion in annual sales in the U.S. (Mogelonsky, 1998). Retailers have found that over 50 percent of mall shoppers purchase on impulse (Nichols et al., 2001). More than one third of all department store purchases were bought on imp...

cardiac conduction system enables the heart to pulsate continuously by producing electric impulse and conducting it. as the anatomical information about cardiac conduction system in human being and other mammals needed in various fields of sciences, such as anatomy, histology, physiology, pathology and cardiology, the present review article intends to provide this basic information about an imp...

This paper describes models for detecting individual and team ball possession in soccer based on position data. The types of ball possession are classified as Individual Ball Possession (IBC), Individual Ball Action (IBA), Individual Ball Control (IBC), Team Ball Possession (TBP), Team Ball Control (TBC) und Team Playmaking (TPM) according to different starting points and endpoints and the type...

Researchers desire to obtain the ball position for each frame for broadcast soccer video to enhance soccer video analysis and understanding. However, the existing algorithms cannot get the satisfactory results. We have developed a detection and tracking algorithm for accurately finding the ball position in broadcast soccer video in the papers [6-8]. Based on our algorithm, we develop this ball ...

No consensus has been reached on how musculoskeletal system injuries or aging can be explained by a walking plantar impulse. We standardize the plantar impulse by defining a principal axis of plantar impulse. Based upon this standardized plantar impulse, two indexes are presented: plantar pressure record time series and plantar-impulse distribution along the principal axis of plantar impulse. T...

Anatase-to-rutile phase transformation was studied in milled and unmilled samples. Ball milling was carried out in two types of ball mills, planetary and tumbler, with a ball-to-powder ratio of 40:1 over 2-48 hours. First, the unmilled samples were heated in the furnace at various temperatures for different periods of time. The results revealed that the anatase-to-rutile transformation comple...

The motion of the ball thrown by a pitcher is influenced by three forces: gravity, drag force due to air resistance, and lift force which deflects a ball vertically or laterally due to ball spin. The lift force acting on the ball increases with spin rate and movement speed when the spin axis of the ball is orthogonal to the direction of ball movement. Among individual pitchers there were great ...

We propose an adaptive method that can estimate 3D position of a soccer ball by using two viewpoint videos. The 3D position of a ball is essential to realize a 3D free viewpoint browsing system and to analyze of soccer games. At an image processing step, our method detects the ball by selecting the best algorithm based on the ball states so as to minimize the chance to miss the ball and to redu...
