the aim of the present research was to compare the performance evaluation indicators of club coaches from experts, athletes and coaches' viewpoints. the statistical population included all physical education experts of guilan province, heads, deputy heads and secretaries of physical education boards, athletes and coaches from rasht city (n=470) and 345 subjects (73.4%) participated in the ...

Computational steering allows researchers to monitor and manage long running, resource intensive applications at runtime. Limited research has addressed high performance computational steering. High performance in computational steering is necessary for three reasons. First, a computational steering system must act intelligently at runtime in order to minimize its perturbation of the target app...

PURPOSE: To determine the relationships between objectively measured and self-reported physical activity, sedentary behavior, and academic performance in Finnish children. METHODS: Two hundred seventy-seven children from five schools in the Jyväskylä school district in Finland (58% of the 475 eligible students; mean age 12.2 years; 56% girls) participated in the study in the spring of 2011. Sel...

Performance Analysis of Physical Layer Network Coding

any designers expect processor performance to keep improving at the current rate indefinitely as feature sizes shrink. However, as wire delays become a larger percentage of overall signal delay and as clock speeds grow faster than transistor speed, I believe performance increases will ultimately fall off. These delays are inevitable simply because wires are not keeping pace with the scaling of ...

In signature authentication schemes, a candidate signature presented for authentication is compared to a previous signature measurement. Uniqueness of a signature is a result of a random physical process underlying the signature formation. In this paper, we model signatures as realizations of random processes with known statistics. Rate functions for the false alarm and miss probabilities are d...

Mental fatigue is a psychobiological state caused by prolonged periods of demanding cognitive activity. Although the impact of mental fatigue on cognitive and skilled performance is well known, its effect on physical performance has not been thoroughly investigated. In this randomized crossover study, 16 subjects cycled to exhaustion at 80% of their peak power output after 90 min of a demanding...

Genes undoubtedly play a role in the development of a successful athlete. This view has flourished on anecdotes such as the observation of a child who displays the same aptitude for a particular sport as one of their parents, or a pair of sisters who both excel in the same discipline. However, the conclusions made from this type of observation have an obvious limitation: that similar environmen...
