Evaluation of the cementite morphology influence on the hydrogen induced crack nucleation and propagation path in carbon steels
منشور في 2022"…A drastic load decrease in the load-displacement (L-D) curve happened under −1550 mV charging for both microstructures accompanied by a straight crack growth path in spheroidite microstruc-ture, independent of grain boundaries or ferrite-cementite interfaces while a competition between the shear crack growth mechanism and the interfacial cracking determines the crack growth path in the lamellar microstructure.…"

Design and analysis of PV fed high-voltage gain DC-DC converter using PI and NN controllers
منشور في 2022"…When the converter switch comes under active state two capacitors are discharged in series, similarly when the converter switch under inactive state those two capacitors are charged in parallel through the coupled inductor (CI) energy so, to get a high voltage at the converter output side. To reuse the leakage-inductor (LI) energy of the CI with the help of a passive clamp circuit for reducing the voltage stress across the switch, similarly switch has less resistance so conduction losses also decreased. …"
