Theory and experiment on the London moment is reviewed. A simple mathematical model is motivated and then used to study the responses of a spherical superconductor to an external field and to rotation. It reveals a connection between perfect diamagnetism (Meissner effect) and the London moment. In the model neither of these are exact but the deviation from B = 0 internal field in the former and...

A systematic method for link/connection-wise end-to-end performance evaluation in queueing networks receiving heterogeneous Markov-modulated Poisson processes (H-MMPPs) is proposed. The method consists of (i) connection-wise nodal performance analysis; (ii) tagged departure process analysis; and (iii) moment matching. For the tagged departure process of an H-MMPPs/G/1 queue, we propose two deco...

analytical detection of cracking in connections of steel moment resisting frames using simple damage indices is important since these cracks are not visible unless the connections are uncovered. in this paper, applicability of three cumulative damage indices for detection of cracking in a cover plate welded moment connection is investigated. the damage indices considered in this study are based...
