The bionic sound detector based on the principle of Ormia ochracea fly’s coupled ears is a miniature directional microphone that sensitive to pressure gradient. In this work, silicon micro-electro-mechanical system diaphragm consisting two interconnected wings designed and prepared, fiber-optic Fabry-Pérot interferometric constructed using diaphragm, characteristics are studied theoretically ex...

Wind power resource development is increasingly becoming the focus of the current research and development in various countries' relevant scientific institutions. To make sure the secure and reliable operation of wind turbine generator, the study develops the wind turbine generator dynamic reliability test system. When the fault of gearbox and spindle occurs, their features of vibration signals...

Larger vibration and noise often exist in agricultural machinery due to the harsh working environment high power. The rubbing machine is one of indispensable pieces equipment agriculture livestock industry, it affected by large constraints on its promotion use. To reduce machine, characteristics spindle rotor were first analysed modal simulation, thus determining larger contributions vibration....

1. It is an old observation that non-volitional arm abduction movements accompanied by a sensation of arm lightness often occur as an after-effect following forceful voluntary arm abductor contractions against a restraint. In the present study we have tested the hypothesis that such non-volitional, so-called 'postural after-contractions' are tonic reflex responses to an enhanced resting dischar...

The possibility that descending systems have differential actions on the spinal interneurons that receive input from muscle afferents was investigated. Prolonged, physiological inputs were generated by stretch of the triceps surae muscles. The resulting firing patterns of 25 lumbosacral interneurons were recorded before and during a reversible cold block of the dorsolateral white matter at the ...

(S u m m a r y) After a historical review of science and technology developments which leads to the invention of transcranial magnetic stimulation (TMS) (Chapter 1) in the next chapter (Chapter 2) the basic information for functional role of motor cortex in motor control is given. An essential part of the book is devoted to the studies of sensorimotor integration using TMS. Sensorimotor integra...

Abstract Based on the inertial vibration excitation device, a biaxial fatigue loading system for wind turbine blades is established by using visual inspection technology and virtual spindle decoupling to control motion of blades. The image feature point tracking method used detect blade state. Considering frequency characteristics, phase difference between exciting force displacement detected b...
