On-line defects detection of structural component of track crane such as crane boom, outriggers, turntable and vehicle frame, is a difficult problem of nondestructive testing (NDT). In the present study, the usefulness of acoustic emission (AE) measurements for the detection of welding crack defects in the specimen made of HG70 steel, which is widely used for manufacturing structural component ...

Background: Hemodialysis patients experience pains induced by cannulation of an arteriovenous (AV) fistula. The effect of mirror therapy on patients’ pain severity has not been investigated in individuals living with hemodialysis. Aim: The purpose of the present study was to investigate the effect of mirror therapy on AV fistula cannulation-related pain s...

The construction and use of a dual radiator Ring Imaging Čerenkov (RICH) detector is described. This instrument was developed for the HERMES experiment at DESY which emphasises measurements of semi-inclusive deep-inelastic scattering. It provides particle identification for pions, kaons, and protons in the momentum range from 2 to 15 GeV, which is essential to these studies. The instrument uses...

The protection of concrete structures against corrosion in marine environments has always been a challenge due to the presence of a saline solution-A natural corrosive agent to the concrete paste and steel reinforcements. The concentration of salt is a key parameter influencing the rate of corrosion. In this paper, we propose an optical fiber-based salinity sensor based on bundled multimode pla...

Embedded Systems have a very important role in the modern life. We use them in our home, work, transportation, medical procedures, leisure time and so on. Despite of its great importance to our lives this kind of system steel lake a better process to improve the quality of its software. In this paper we present the results from a field research that focused the state of the practice of the embe...

in order to investigate the role of multi-wall carbon nanotubes (mwcnts) on fracture mechanism of epoxy nanocomposites, a series of tensile standard specimens reinforced with different carbon nanotube contents (0, 0.3, 0.6 and 1 wt%) were produced. the fracture surfaces of the produced nanocomposites were evaluated using scanning electron microscope (sem). the results show that the surface frac...
