Proton Exchange Membrane Fuel Cells (PEMFCs) represent a promising clean energy technology for electric vehicle (EV) applications due to their high efficiency and zero-emission operation. Precise parameter estimation is essential for effective simulation, optimal control, and per…

This study aims to investigate and compare the evolution of microstructure and mechanical behavior in API X70 steels welded using SMAW techniques. A comprehensive analysis of the microstructure revealed that the weldability of low-carbon X70 steels is significantly influenced by …

The objective of this paper is to study the feasibility of detection and characterization of damage in glass fiber composite laminated plates using S0 Lamb waves. The characterization of this waves is first clarified experimentally by plotting these dispersion curves and their at…

This article investigates the devise issue of a practical finite-time output-tracking control for uncertain nonlinear nonstrict-feedback systems subject simultaneously to time-varying output constraints (TVOC), actuator saturation, and bounded unmatched disturbances. An adaptive …

In this study, response surface methodology (RSM) was employed to optimize the welding parameters’ effects on mechanical properties of dissimilar welds between Cr-Mo steel grade (P11) and austenitic stainless steel (AISI 316LN). To determine the best welding parameters, variance …

In this article, an adaptive fuzzy tracking control scheme is developed for a class of pure-feedback uncertain nonlinear systems in the presence of time-varying full-state constraints (TFSCs), actuators’ nonlinearities and external disturbances. Fuzzy logic systems (FLSs) are emp…

The purpose of this study is to evaluate in detail the usability of new cellulosic fibers extracted from the stem of the plant Strelitzia reginae, as a potential reinforcement for polymer composites. The morphological, physical, thermal, and me chanical properties of fibers were …

The investigation presented in this paper focuses on the effect of surface texture on the adhesion of a paint coating as well as the influence of shot peening regime parameters on the surface isotropy indicator "Str" and on the fractal dimension "Df". The tests have been organize…

Considering corrosion rate during the remaining life assessment of aging pipelines is fundamental to calculate the interval between two consecutive inspections. A total of 798 internal and external corrosion defects have been detected, using the Magnetic Flux Leakage intelligent …

Multilayer thin coatings (~3 µm in thickness) were deposited using reactive radio frequency magnetron sputteringon Ti-6Al-4 V substrate for biomaterial applications. Films are a combination of hard zirconium nitride with pure tantalum, used to manage interfacial stress and to avo…
