Advanced LIGO searches for gravitational wave events using two 4-km Fabry–Pérot Michelson interferometers separated by a 3000 km baseline. Each interferometer is illuminated with up to 125 W of 1064 nm light from a frequencyand intensity-stabilized Nd:YAG laser. This laser is frequency-locked to the interferometer’s commonmode arm length, which acts as a 4-km-long reference cavity with a 1 Hz l...

10 Abstract Performing any behavior requires perceiving 11 affordances—whether and how that behavior can be per12 formed. Perception of affordances exhibits action scaling— 13 choices about when to transition between two different modes 14 of behavior reflect the fit between action capabilities and en15 vironmental properties. The boundary between distances that 16 are perceived to be reachable...

This paper introduces a novel interface ‘3D head pointer’ for the operation of wearable robotic arm in 3D space. The developed system is intended to assist its user execution routine tasks while operating arm. Previous studies have demonstrated difficulty faces simultaneously controlling and their own hands. proposed method combines head-based pointing device voice recognition manipulate positi...

Soldiers should always keep their physical condition in good order. Cardiorespiratory endurance, abdominal muscle strength and arm are important aspects that support soldier performance. endurance is to ensure soldiers can work according the targeted duration. Good supports minimize back pain. often had carry heavy loads backpacks be carried a certain distance also confirmed undergo shooting dr...

introduction: in order to make a dimensional proportion between human and equipment or environment, anthropometric data bank is essential. anthropometry has an important role in industrial management and ergonomic design. this information is needed to be collected regularly in every society. the purpose of this study was to determine arm length to height ratio according to gender in adults, bet...

PURPOSE The primary aim of this study is to determine the principal somatic and motor determinants for elite climbers. METHODS Twenty climbers were examined [age: 28.5±6.1 years].The runners were divided into two groups based on their climbing level, according to the International Rock Climbing Research Association (IRCRA). Elite climbers represented a 8b-8c Rotpunkt (RP) climbing level (n = ...

The aim of this study was to compute a swimming performance confirmatory model based on biomechanical parameters. The sample included 100 young swimmers (overall: 12.3 ± 0.74 years; 49 boys: 12.5 ± 0.76 years; 51 girls: 12.2 ± 0.71 years; both genders in Tanner stages 1-2 by self-report) participating on a regular basis in regional and national-level events. The 100 m freestyle event was chosen...
