The Training and Development of Elite Sprint Performance ...

Power, technique, and sprint-specific endurance are considered key underlying determinants of 100-m sprint performance [3, 11,12,13,14,15,16, 24, 33, 34].A very strong relationship exists between maximal horizontal power output and sprint performance; the shorter the sprint distance is, the higher the association with maximal horizontal power output [].

Improving the thermoelectric performance in …

The thermoelectric performance of Mg 3+x Sb 1.5 Bi 0.49 Te 0.01 was improved by reducing the amount of excess Mg (x = 0.01-0.2). A 20% reduction in effective lattice thermal conductivity at 600 K was observed by decreasing the nominal x from 0.2 to 0.01 in Mg 3+x Sb 1.5 Bi 0.49 Te 0.01, leading to a 20% improvement in the figure-of-merit zT.Since materials …

Power factor correction: A guide for the plant engineer

To determine power factor (PF), divide working power (kW) by apparent power (kVA) . In a linear or sinusoidal system, the result is also referred to as the cosine θ.. For example, if you had a boring mill that was operating at 100 kW and the apparent power consumed was 125 kVA, you would divide 100 by 125 and come up with a power factor of 0 .80 .
