Standard Penetration Test (SPT) and Cone Penetration Test are widely used in geotechnical investigation methods for railway roadbed. However, the standard penetration test cannot be used on the track in electric lines, since the equipment may contac
suggested, then built and tested using the LabVIEW environment. Simulated using sensor measurement data offered by National Institute of Standards and Technology (NIST), possibility of reducing false positive and false negative errors is verified.
Test coil for a reed switch is test equipment for quality verification of a reed switch, and a test coil consists of a coil and core. In this study, magnetic property of test coil and permanent magnet on a reed switch is compared by using finite ele
This paper aims to clarify the structural mechanism of gold price determination by building up a mediation effect model and empirically testing it with monthly data of 416 observations in the period from Dec. 1978 to July 2013. The empirical te
We performed impact test to estimate necessary explosive charge weight for cutting the cable whose diameter is 22 ㎜. The impact test results were analyzed by Probit method. The cutting energy was calculated 37.7 J with 99.99% probability at 99% re
