Assessment and Monitoring for Railway Tracks Reliability and Safety using Nondestructive Testing Measurement Systems

The deterioration of railway tracks raises great concerns about the integrity of assessments and evaluations of railway tracks currently in service. Integrated inspection strategies coupled with innovations in inspection technology can lead to significant improvements in operational cost efficiency and reliability without the requirement of a fundamental shift in the existing understanding o...

Design of Highly-sensitive Current Monitor with Hts Squid and Hts Magnetic Shield

A high-temperature superconducting (HTS) magnetic shield based on Bi(Pb)2-Sr2-Ca2-Cu3-Ox (Bi-2223) was fabricated by plasma spraying for the purpose of observing a somatosensory-evoked magnetic field generated from the human brain[1]. Recently, a Bi-2223 cylindrical magnetic shield was developed by dip-coating on a 99.9 % MgO ceramic substrate. A highly-sensitive current monitor using this HTS ...

HTS dc-SQUID flip-chip magnetometers and gradiometers

Biomagnetic research requires measuring systems with the utmost sensitivity to magnetic fields. The strongest challenge is fMEG measurements with a typical (20 – 200) fT peak-to-peak signal magnitude. An average R-wave magnitude of a fMCG signal is ∼2 pT. Measuring in a frequency bandwidth of about 100 Hz with a signal-to-noise ratio of ∼10 demands a system noise for fMCG measurements ∼20 fT/√H...

Nondestructive Testing System for Eggshells Based on DSP

In order to check and eliminate the cracked eggs quickly and exactly in the process of egg products, a nondestructive testing system for eggshells based on digital signal processor (DSP) was established. The system utilized a TMS320VC33 DSP as a hardware platform, and has many functions such as controlling knock-equipment, sampling and processing the acoustics signals, judging the cracked-shell...
