The Acute and Chronic Muscle Adaptations Following six weeks of "No Load" and Traditional High Load Resistance Training
… appears to be true, independent of the external load, provided sufficient tension is achieved. PURPOSE: The purpose of this study was to remove the influence of an external load and compare the acute and chronic muscle adaptations of “No Load” training to traditional High Load training. METHODS: …

Effects of Increases in Mental Workload on Avoidance of Ground Hazards
New sensor and display technologies are expected to enhance the performance of soldiers by providing them more information about the battlefield. However, there is concern that greater quantities of information and increases in mental workload might cause distraction, reduce attention to dangers in …

Harmonic Reduction IN a Single-Switch Three-Phase Boost Rectifier With Harmonic-Injected PWM
… The variations of the small-signal model against load are demonstrated, and the compensator design is discussed. The results show that at no load, the dominant pole of the control-to-output transfer function approaches the origin and causes more phase delay, making the control design difficult. To …
