Image Segmentation Methods for Non-destructive testing Applications
CoRR, 2021 In this paper, we present new image segmentation methods based on hidden Markov random fields (HMRFs) and cuckoo search (CS) variants. HMRFs model the segmentation problem as a minimization of an energy function. CS algorithm is one of the recent powerful optimization techniques.

Comparative study of 36 mm-diameter rope in five aerial ropeway installations using a non-destructive method [PDF]
, 2020 Visual inspection of wire rope is the most conventional method but it can be inadequate, especially for long rope. Non-destructive evaluation using magnetic methods is an important means for monitoring the performance of haulage rope. A rope tester, used

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations
FEBS Letters, EarlyView.The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...
