Image-Based Feature Extraction Technique for Inclined Crack Quantification Using Pulsed Eddy Current
Locating and characterizing rolling contact fatigue (RCF) cracks in rails is gaining attention the railway industry. Eddy current pulsed thermography (ECPT) can detect such by combining benefits of electromagnetic excitation thermal diffusion. To date, most studies focus on investigating specific features based artificial defects, verification real lacking. In this article, to establish best me...
This paper reviews recent developments of eddy current pulsed thermography (ECPT) for material characterization and nondestructive evaluation (NDE). Due to the fact that line-coil-based ECPT, with the limitation of non-uniform heating and a restricted view, is not suitable for complex geometry structures evaluation, Helmholtz coils and ferrite-yoke-based excitation configurations of ECPT are pr...
T cells primed specifically for the envelope glycoprotein of Friend murine leukemia helper virus (F-MuLV) were prepared by immunizing mice with a recombinant vaccinia virus that expressed the entire env gene of F-MuLV. Significant proliferative responses of F-MuLV envelope-specific, H-2a/b T cells were observed when the T cells were stimulated with antigen-pulsed peritoneal exudate cells (PEC) ...
