The detection and quantification of the rolling contact fatigue (RCF) in rail tracks are essential for safety condition-based maintenance. tomographic reconstruction is challenging work. x-ray unable to do in-situ inspection effectively. This paper proposes a new approach RCF construction using 3D eddy current pulsed thermography. A differential time-square-root (sqrt) temperature drop (DTSTD) ...

The Pareto-efficient combustion (PEC) framework is extended for predicting transient ignition in turbulent flames. PEC formulation utilizes a drift term to assess the compliance of specific submodels with underlying flow-field representation. This consider autoignition delay as process interest, and time homogeneous isobaric reactor utilized surrogate. Combustion models considered are steady-st...

Nondestructive evaluation NDE is implemented in various industrial sectors. Different modalities have been developed for NDE applications during the last few decades. There is a tradeoff between advantages and limitations associated with each technique and even within the same technique using different inspection parameters. This research is oriented to enhance electromagnetic NDE using image f...

The need for convection compensating methods in NMR has been manifested through an increasing number of publications related to the subject over the past few years (J. Magn. Reson. 125, 372 (1997); 132, 13 (1998); 131, 126 (1998); 118, 50 (1996); 133, 379 (1998)). When performing measurements at elevated temperature, small convection currents may give rise to erroneous values of the diffusion c...
