In particular, a three-dimensional coordinates method was used to analyze the last three strides before touchdown, the touchdown techniques, and the movements after takeoff toward the bar. An analysis of the, data for the biomechanical characteristics of the world's best high jumpers could contribute to an improvement in the performance of a national high jumper. The first conclusion of the data analysis was that the arm movements of the gold medalist, J. -

Topological Entropy for Automorphisms of Totally Disconnected Locally Compact Groups

We give a “limit-free formula” simplifying the compu- tation of the topological entropy for topological automorphisms of totally disconnected locally compact groups. This result allows us to extend to our setting several basic properties of the topological entropy known for compact groups. 1. Introduction In this paper we consider the topological entropy for topological auto- morphisms of totally disconnected locally compact groups. For a locally compact group G, let µ denote a left Haar measure on G. Moreover, let B(G) be the family of all open compact subgroups of G.A totally disconnected locally compact group G has B(G) as a local base at 1, as proved by van Dantzig in [14]. In [1] Adler, Konheim and McAndrew defined the topological entropy for continuous self-maps of compact spaces. Later on, in [3] Bowen in- troduced another notion of topological entropy for uniformly continuous self-maps of metric spaces. -
Comparative Analysis on Speed Distribution of Women 400M Finalist Athletes in the World Athletics and Olympic Championships
S. M. Ramadan Theories & Applications, the International Edition Printed Version : (ISSN 2090-5262) Online Version : (ISSN 2090-5270) July 2014, Volume 4, No. 2 Pages (124 - 130) Comparative Analysis on Speed Distribution of Women 400m Finalist Athletes in the World Athletics and Olympic Championships. S. M. Ramadan Department of sports training – the faculty of sports education for women - Alexandria University, Egypt. Abstract The 400m dash sprint is considered to be one of the most interesting and difficult sprint events in the sport of athletics, this is why sports scientists are paying much attention now to develop the means of helping athletes to enhance their performance and numerical achievements through investigating the mechanical and kinematical and other scientific variables of the race trying to obtain reliable results as a base for modern training techniques. This study aims for presenting a comparative analysis on speed distribution of women 400m finalist athletes in the world athletics 2011 and 2012 Olympic championships by means of correlation analysis, regression analysis and cluster analysis, every 50m segment result has been studied as well as total results of world elite women 400m athletes. The main purpose is to reveal the relations between different 50m phases and the final 400m result, and to find out the basic features of their speed distribution, in order to provide scientific references for our women athletes to increase the ability of reaching higher performance levels. Key Words: women, world, 400m, analysis, speed, distribution will have to ask yourself am I going to compete or am I Introduction going to cave?" Michael Johnson, who won the 200 meter he 400 meters, or 400 meter dash, is a common and 400 meter at the 1996 Olympics - and still holds the 400 T sprinting event in track and field competitions. -
