The Effects of High Resistance Training Volume During Caloric Restriction Among Resistance Trained Individuals on Body Composition, Resting Energy Expenditure, 24-hour Total Nitrogen Balance and Maximal Strength

Athletes employ weight-loss protocols to lower fat mass (FM) and maintain fat-free mass (FFM) for performance purposes. Under mass-stable conditions, high resistance training volumes (HVRT) have been associated with greater increases in FFM than low ...

Modeling and simulation of HVRT and LVRT enhancement capability for doubly fed induction generator based wind energy conversion system

International Journal of Engineering & Technology, 2018
Generation of power using wind turbine is more across the globe, but a problem related using wind method of power generation is volt-age variation across the grid. The performance of wind turbine goes below the specified level during grid voltage variation. It might be due to overvoltage or under voltage condition.
