Abstract: A lot of progress is made in the last decade concerning the theoretical and practical aspects of eddy current testing. In addition to the defect characterization, actual studies deal with the metallurgical evaluation of materials. Surface examination allows the prediction of the material strength and consequently its life time. In order to obtain various microstructures and to modify ...

Use of the grounded theory research method (GTM) is increasing across many fields of inquiry. Understanding the GTM and how to apply it is therefore a key task for researchers examining the possibility of using this method in their research. Since its introduction by Glaser and Strauss in 1967, GTM has evolved into two major streams, and there has been a continual debate about the choice betwee...

Individual effect of thermomigration (TM) and combined effect of TM and electromigration (EM) on the microstructural variation in Sn8Zn3Bi was investigated by stressing line-type Au/Ni–P/Cu-Sn8Zn3Bi-Au/Ni–P/Ni solder joints with a 5 9 10 A/cm alternating current (AC) or direct current (DC) at 110 C. Due to the different thermoelectric characteristics of Cu and Ni wires, a thermal gradient of 19...

Although tDCS has been shown to improve motor learning, previous studies reported rather small effects. Since physiological effects of tDCS depend on intensity, the present study evaluated this parameter in order to enhance the effect of tDCS on skill acquisition. The effect of different stimulation intensities of anodal tDCS (atDCS) was investigated in a double blind, sham controlled crossover...

As one of the solution of the increase problem of the fault current in a power system, the superconducting fault current limiter (SFCL) has been noticed as the attractive device because it has no power loss in a normal time and can limit the fault current rapidly without additional device to detect the fault current. However, the introduction of the SFCL in a power distribution system affects t...
