X‐Ray Computed Tomography Quantifies Primary Phases and Reveals Crack Morphology in High‐Cycle Fatigue of Aluminum Alloy EN AW‐2618A

open access: yesAdvanced Engineering Materials, EarlyView.
Primary phases and a fatigue crack are studied in a forged blank of an aluminum alloy using synchrotron and laboratory X‐ray computed tomography. To image the crack, the fatigue test is interrupted, and a static tensile load is applied to open the crack.

Online burr video denoising by learning sparsifying transform

open access: yesIET Image Processing, 2019
The burrs on high‐voltage copper contact leads to point discharge and device damage. Since the high‐voltage copper contact has different machining batch and the contour various which the machine tool remove is not economic and robot usually is used to ...

Electronic Control System for Optimized Resonance Operation of Dielectric Elastomer Pumps through Self‐Sensing

open access: yesAdvanced Engineering Materials, EarlyView.
A powerful electronic control system enables a dielectric elastomer pump to operate at resonance, matching conventional pump performance. Using self‐sensing to reconstruct load pressure dynamically, the adaptive control adjusts resonance frequency accordingly.

Robust video watermarking with complex conjugate symmetric sequency transform using SURF feature matching

open access: yesCogent Engineering
This article proposes a video watermarking technique by concealing the watermark in the low frequency bands of phase using Conjugate Symmetric Sequency Complex Hadamard Transform (CS-SCHT) and Speeded Up Robust Feature (SURF). The CS-SCHT is effective in

Multi‐Scaled Cellulosic Nanonetworks from Tunicates

open access: yesAdvanced Functional Materials, EarlyView.
Microbial and plant nanonetworks of cellulose have enabled a wide range of high‐performance yet sustainable materials. Herein, a third class of cellulosic nanonetworks is showcased by exploiting the only animal tissue‐producing cellulose nanofibers, i.e., ascidians. An ultrastructure including spherical cells and a microvasculature with diameters of 50–
