Males of the North American cicada Okanagana rimosa (Homoptera: Cicadidae, Tibicininae) emit loud airborne acoustic signals for intraspecific communication. Specialised vibratory signals could not be detected; however, the airborne signal induced substrate vibrations. Both auditory and vibratory spectra peak in the range from 7-10 kHz. Thus, the vibrations show similar frequency components to t...

This paper consolidated the improvements in mechanical properties from the past literature available using Vibratory welding technique. Vibratory welding is a promising method in eliminating the disadvantages experienced by the traditional welding like residual stress due to the electrical energy input which induces vibrations by varying the input parameters voltage, current, amplitude and freq...

This paper reports a non-contact experimental characterization of resonant modes in micromachined spherical shells fabricated by pressure and surface tension driven plastic deformation (glassblowing). For a glass-blown shell with 0.9 mm diameter and 10 μm average thickness, dynamically balanced 4and 6-node vibratory modes were identified at 1.27 MHz and 1.44 MHz, respectively. Without any trimm...

Vibratory feeders are commonly used in industries for part feeding. There are several factors that affect the conveying velocity of parts on the vibratory feeder. Among these, the critical factors such as excitation frequency, amplitude of vibration, mass of part, co-efficient of friction and Length-towidth (L/W) ratio of the part were considered for experimental studies. The percentage of infl...

BACKGROUND Vibratory stimulation is a potential method for the treatment of pain. METHODS The effect of vibration on the forearm on detection (DT) and pain thresholds (PT) induced by electro-cutaneous stimulation were investigated in healthy male and female volunteers. RESULTS Women have lower baseline detection and pain thresholds as compared to men. Furthermore, women but not men report i...

During driving sleeve of cast-in-place piles by vibratory hammers, soils were squeezed into sleeve and then soil plugging was formed. The physic-mechanical properties of the soil plug have direct influence on the load transmission between the sleeve wall and soil plug. Nevertheless, the researches on this issue are insufficient. In this study, finite element and infinite element coupling model ...

This paper proposes a methodology for user-tailored orthosis design 3D printing that aims to give non-expert, user-oriented tool easily generates customized orthosis. Additionally, this work verify the biocompatibility of PLACTIVE™ (PLACTIVE AN1™, nano-additive concentration 1%, Copper 3D, Santiago, Chile) filament after extrusion check its feasibility printed orthoses. A forefinger and thumb w...

For patients suffering from drop foot due to weakness of ankle dorsiflexion muscles, an orthosis provides increased clearance during the swing phase gait, but often restricts other gait functions, such as plantarflexion. Due steady progress in development lighter and smaller actuator technologies, active wearable devices exosuits become relevant for rehabilitation, since they can offer extended...
