This study investigated asymmetry between lower extremities during the landing and takeoff phases of a vertical drop jump (VDJ) in adolescent athletes following anterior cruciate ligament reconstruction (ACLR) examined if performance was affected by reducing height. Thirty-three who underwent ACLR were referred for 3D biomechanical assessment before returning to play (mean age 15.9, SD 1.3 year...

This study explores how the rent-seeking behavior of government may impede economic development and delay industrialization. Introducing a to Schumpeterian growth model that features endogenous takeoff, we find more self-interested engages in taxation, which delays economy’s transition from pre-industrial stagnation modern growth. Quantitatively, completely could have delayed industrialization,...

Although schedule design has further potential to reduce airline operation costs and flight delay, the effectiveness of globally optimal integrating air traffic flow not been discussed thus far. This paper presents a global multi-objective takeoff time optimization efficient schedules that lead minimal congestion provide sufficient resilience against problems. NSGA-II is adopted as technique in...

As an element of a design optimization study of high speed civil transport (HSCT), response surface equations (RSEs) were developed with the goal of accurately predicting the sideline, takeoff, and approach noise levels for any combination of selected design variables. These RSEs were needed during vehicle synthesis to constrain the aircraft design to meet FAR 36, Stage 3 noise levels. Developm...

This article discusses the main aspects of electrical air conditioning systems, as well improving efficiency ESAC using Boeing 787 an example. In course analysis, a comparative calculation was carried out according to criterion takeoff weight increment by Bulaevsky-Shustrov method and its Western counterpart.
