Sports involving throwing, striking and kicking activities, such as tennis, squash, baseball, football, among others, demand the production of maximum speed at the end of the distal segment in a kinematic chain. Research done on the biomechanics of these various, yet somehow similar sporting techniques, suggests that athletes generate large hand and foot speeds as a result of a proximal-to-dist...

This paper presents a new digital communication system called turbocodes m-binary. The advantages of building m-bit compared to the conventional scheme of turbo codes (m = 1), are varied: better convergence of the iterative process, larger minimum distances less punching, lower latency, robustness to the sub-optimality of the decoding algorithm, especially when the MAP algorithm is simplified b...

In this study accumulative roll bonding (ARB) process up to 8 Cycles (equivalent strain of 6.4) at ambient temperature was used in order to improve the mechanical properties of Commercial purity titanium (CP-Ti).Several experiment has been done and Mechanical properties of specimen has been discussed. For investigating optical microscope punching and hardness test were utilized. This is the fir...

Fiber-reinforced composites have a wide range of industrial applications owing to their light weight, high modulus, and good specific strength. Trimming using mechanical punching tool is the fastest way post process fiber-reinforced composites. However, quantitative analyses defects parameters are required analyze damage mechanisms achieve high-quality cut surfaces. In this study, we quantitive...

An activity profile of competitive 3 × 2-min novice-level amateur boxing was created based on video footage and postbout blood [La] in 32 male boxers (mean ± SD) age 19.3 ± 1.4 y, body mass 62.6 ± 4.1 kg. Winners landed 18 ± 11 more punches than losers by applying more lead-hand punches in round 1 (34.2 ± 10.9 vs 26.5 ± 9.4), total punches to the head (121.3 ± 10.2 vs 96.0 ± 9.8), and block and...

Flat slab concrete buildings are widely found in infrastructure such as office and residential buildings or industrial facilities. The susceptibility of progressive collapse of such structures due to accidental loads is highly dependent on the structural performance of the slab-column connections. This paper presents a framework for a simplified reliability analysis and derivation of safety fac...

Research across domains has suggested that agents, the doers of actions, have a processing advantage over patients, the receivers of actions. We hypothesized that agents as "event builders" for discrete actions (e.g., throwing a ball, punching) build on cues embedded in their preparatory postures (e.g., reaching back an arm to throw or punch) that lead to (predictable) culminating actions, and ...
