Abstract In recent years, a number of studies in Non-Destructive Evaluation (NDE) have been conducted on the sensitivity probes assessing depth cracks based input stimulation. Range frequency and crack suggested as relevant features for excitation waveform forms. The construction an encircling coil differential probe (ECDP) absolute (ECAP) was discussed this paper. For defect, Multi-Frequency (...

The peripheral vestibular system is critical for the execution of activities of daily life as it provides movement and orientation information to motor and sensory systems. Patients with bilateral vestibular hypofunction experience a significant decrease in quality of life and have currently no viable treatment option. Vestibular implants could eventually restore vestibular function. Most vesti...

Aneurysms of the common iliac artery (CIAA) are most commonly seen in association with an abdominal aortic aneurysm (AAA). Isolated CIAAs, in the absence of an AAA, are uncommon. Similar to AAAs, CIAA may develop intraluminal thrombus (ILT). As isolated CIAAs have a contralateral common iliac artery for comparison, they provide an opportunity to study the haemodynamic mechanisms behind ILT form...

BACKGROUND Experimental results are commonly fitted by determining parameter values of suitable mathematical expressions. In case a relation exists between different data sets, the accuracy of the parameters obtained can be increased by incorporating this relationship in the fitting process instead of fitting the recordings separately. METHODS An algorithm to fit multiple measured curves simu...

This study aims to examine the change in microstructural and hardness values AA7075 aluminum alloy, which is frequently preferred aviation industry by applying Equal Channel Angular Pressing (ECAP) method. ECAP method, one of plastic deformation methods, has been successfully carried out 0.025mm/sec pressing speed 200°C temperature for a different route (A, Bc, C) number passes (2, 4, 8). The c...

Mg–2Y–0.6Nd–0.6Zr alloy was first deformed by equal channel angular pressing (ECAP), then rolled and under ultralow temperature conditions (liquid nitrogen immersion), finally annealed. Optical microscopy (OM), electron backscatter diffraction technology (EBSD), transmission (TEM) were used to analyze the evolution of multiscale microstructure changes in mechanical properties temperatures vario...

In this research, samples of AlMg0.7Si aluminum alloy are deformed up to three passes using equal channel angular pressing (ECAP). Formation of a sub-micron structure after three passes of ECAP is demonstrated. Microstructural stability of the samples is investigated at temperatures of 300-500 °C. At 300 °C, fine recrystallized structure forms after 10 min which remains stable when the ...
