Sports and Technology

This research article examines the use of technology in sports from a double-edged perspective. This article focuses on some of the remarkable technological advancementwhich has revolutionized and impeded the sport industry as whole. From introduction ofmodern technology in training of players to reducing the faults in game through variousmeasures like Video Assistant Referee and Goal Line Technology, the development andimplementation of technology in sports has played a vital role in improving the standardof game, for players as well as for spectators. However, only a few research works havebeen conducted and a minimum of articles have been written on the hindrances causedby those technology and problems with proper implementation of technology in sports. This paper is prepared after in-depth research of news by various sports portals, channels and magazines along with the views of experts of diff erent sports who have recognizedthe need and development of technology in sports. This paper further elucidates on howthe advancement has benefi tted and the fi eld of sports with substantial infl uence on game results by mitigation of errors which were inevitable when technology was not usedin past. Based on elucidation of different primary and secondary sources, such as journal articles, newspapers, magazines, sports portals and events, case laws, statutes, this research article is mostly qualitative than quantitative.

Particle-Resolved Direct Numerical Simulations of Clay Particles in the Absence of Gravity.

<p>Flocculation processes of clay particles are usually influenced by settling effects due to gravity. This inhibits the investigation of the effects of cohesive forces in isolation and limits our understanding of flocculation processes over long time scales that are more common in aquatic environments. To address this issue, particle-resolved Direct Numerical Simulations (pr-DNS) are conducted to simulate the flocculation processes of a preceding campaign of microgravity experiments that have been performed onboard the International Space Station (ISS). The experiments with clay suspensions of kaolin (8 ppt) in saline water (35 PSU) have been examined in the absence of gravity over a time period of more than 100 days by taking pictures of the suspension at regular time intervals. The results of the image analysis are used to validate the numerical computation of clay aggregate growth over time. The simulations are based on a numerical cohesion model which includes the fluid-particle interaction via the Immersed Boundary Method (IBM) by geometrically resolving the flow field around the suspended particles. To this end, monodisperse spherical primary particles <em>w</em>ere randomly placed in a triple-periodic box and exposed to an oscillatory flow. This oscillation is used to mimic the jitering motion of the ISS, which may be caused by onboard instruments as well as the drive-line technology. In this talk, we will present the results of these simulations and link them to the observations provided by the microgravity experimtents.</p>

The Analysis Of Influence Of Productions Of Open Mountain Works On Environment At Formation Of Various Zones On Deep Open-Cast Mines

In the article ways of perfection of processes of chisel, explosive and excavation-loading works, moving of career cargoes, a sailing of formation and application of is cyclic-line technology on deep open-cast mines with is difficult-structural conditions for the purpose of reduction of an ecological damage by environment are considered. The analysis of studying of experience of development of mountain works on is difficult-structural deposits fulfilled in the open way where depth of mountain works reaches a point more than 500 m with division into the natural -technological zones is carried out.
