An attempt to develop a double-layered AZ91 build structure through severe plastic deformation route

In this preliminary investigation, a double-layered AZ91 magnesium structure was developed using solid-state friction stir additive manufacturing (FSAM) by varying the tool rotation speed and traverse speed. Cross-sections of the samples were examined using optical macroscopy, wh...

Comparative study of chemical treatments on the mechanical and moisture absorption behavior of coccinia indica fiber-reinforced epoxy composites

Rising demand for eco-conscious-based functional material drives the focus of materials science field scientists towards research on natural fiber-reinforced polymer composites (NFRPCs), which hold significant attention due to their high strength-to-weight ratio and sustainabilit...

Correlation-Guided Graph Transformer Networks for Cold-Start Group Event Recommendation in Social Networks

The emergence of social platforms has seen the importance of group event recommendation increase as a result of the fast rate of growth. In comparison to single-user recommendation, the group recommendation has to capture overall preferences and overcome the extreme sparsity, lon...

SAFER-Net: a spatial attention and feature enhanced representation network for EEG-based driver drowsiness detection

Drowsiness during driving is a risk causing road accidents worldwide, necessitating early detection of drowsiness. Electroencephalography (EEG) is used for developing reliable drowsiness detection system. EEG-based works utilize temporal-spatial representation, channel dependency...

Tribological and acoustic evaluation of non-asbestos copper-free automotive brake pads with olefin elastomers

Purpose This study aims to develop and evaluate copper-free brake pads using an olefin-based elastomer as an alternative to conventional nitrile butadiene rubber (NBR)-based formulations. This research also benchmarks the newly developed pad against the commercial brake pad to de...

Development and characterization of a PVA/ZnO/curcumin/andrographis paniculata extract nanofibrous membrane for wound healing applications

Nanofibrous membranes are emerging as promising wound dressing materials due to their extracellular matrix-mimicking architecture. However, pristine nanofibers are insufficient to address the demanding requirements of chronic wounds. Thus, the development of multi-component nanof...

Numerical and machine learning framework for strategic fin design to accelerate phase change material melting in advanced enclosures

The melting behavior of phase change materials (PCMs) is numerically investigated in rectangular, trapezoidal, and heptahedral enclosures equipped with identical V-shaped fins, under coupled parametric variations. The investigated parameters include PCM type (RT-25 to RT-38), fin...

Trajectory Controllability and Ulam–Hyer's Stability for Higher‐Order Coupled Hilfer Fractional Neutral Stochastic Integro‐Differential Equations via Measure of Non‐Compactness

ABSTRACT The present manuscript investigates the controllability and stability of coupled higher‐order Hilfer fractional neutral stochastic integro‐differential systems (HFNSIDSs) driven by fractional Brownian motion (FBM). To the best of our knowledge, the study of coupled highe...

A comparative review of adaptive laboratory evolution in Saccharomyces cerevisiae and Yarrowia lipolytica: mechanistic understanding, biotechnological applications, and industrial prospects

Adaptive laboratory evolution (ALE) is a powerful technique in yeast strain development, and it also helps in the understanding of microbial adaptations and development of robust strains for industrial biotechnology. Adaptive mutations enable strains to withstand stressors found...

Performance-based selection of cathodic-arc PVD TiAlN and AlCrN coatings for SR34 piston-ring steel: Tribological, tribocorrosion and thermal assessment

Piston rings operate under severe sliding conditions, high temperatures, and corrosive environments, making surface degradation a critical factor affecting engine durability. This study presents a comparative evaluation of cathodic-arc physical vapor deposition (CA-PVD) TiAlN and...
