The purpose of this study was to describe biomechanical parameters of head, upper and lower body extremities during a straight right punch throw related to performance and injury mechanism. Subjects were eight elite right-handed male (age 20.4 ± 2.1yrs height 177.4 ± 8.5 cm mass 70.4 ± 16.8 kg) amateur boxers. 3D motion analysis was used to assess the kinematics of the right side extremities ...

In this paper, an adaptive neuro fuzzy sliding mode based genetic algorithm (ANFSGA) controlsystem is proposed for a pH neutralization system. In pH reactors, determination and control of pH isa common problem concerning chemical-based industrial processes due to the non-linearity observedin the titration curve. An ANFSGA control system is designed to overcome the complexity of precisecontrol o...

Herein is described an environmental and life cycle cost (LCC) analysis of one switched reluctance motor (SRM) drive and two inverter-fed induction motor (IM) drives. The two types of drives are compared based on critical reasoning, and European Commission (EC) Regulation 640/2009 is considered. Environmental impact and LCC were evaluated according the Methodology for the Ecodesign of Energy-Us...

The authors have been developing a pipe bender which fabricates pipes of three-dimensional complex shapes from straight pipes based on the penetration bending method. This bender is composed of a movable die supported by a drive mechanism, a fixed die and a pipe feeder. A 3-RPSR parallel mechanism was employed as the movable-die drive mechanism, and its kinematic design was figured out under th...

Drug addiction is a complex brain disorder, characterized by the loss of control over drug seeking and drug taking behavior, and by the risk of relapse, even after a prolonged period of abstinence. This disorder may have its source in a disturbed balance of drive-related behaviors, which control appetitive reactions aimed at seeking contact with an addictive substance. The act of consumption be...

The fact that piezoelectric ceramic transducer (PZT) precision drive systems in 3D printing are faced with nonlinear problems with respect to positioning, such as hysteresis and creep, has had an extremely negative impact on the precision of laser focusing systems. To eliminate the impact of PZT nonlinearity during precision drive movement, mathematical modeling and theoretical analyses of each...

This paper shows how system call traces can be obtained with minimal interference to the system being characterized , and used as realistic, repeatable workloads for experiments to evaluate operating system and le system designs and connguration alternatives. Our system call trace mechanism, called Ultra, captures a complete trace of each Unix process's calls to the operating system. The perfor...

The multidimensional deployment of large-scale spatial solar arrays has been the basis for high-power advanced spacecraft and a symbol leaps forward in aerospace technology. Activated passive drives have often used combination to implement driving mechanism arrays, which can reduce impact locking process. For first time, novel active speed-limit was introduced into two-dimensional secondary dep...
