Design and Validation of an Artificial Intelligence-Driven Digital Twin for Real-Time Monitoring and Control in Polymer Composite Manufacturing
Abstract: Polymer Matrix Composites (PMCs) have become indispensable in high-performance sectors such as aerospace and automotive engineering, offering exceptional strength-to-weight ratios that outperform traditional metals in many demanding applications. However, the reliability of manufacturing PMCs via Vacuum-Assisted Resin Transfer Molding (VARTM) is frequently undermined by stochastic process variabilities. Unpredictable fluctuations in thermal history, preform permeability, resin rheology, and ambient conditions often lead to some defects; namely voids, dry spots, and incomplete …

Integrated Surface Water–Groundwater Dynamics: Implications for Pollution Pathways, Prevention, and Environmental Control
Abstract: Water resources worldwide are increasingly threatened by pollution pressures amplified by climate change and intensified human activities. The vulnerability of surface water and groundwater systems to contamination is strongly governed by their dynamic hydrologic connectivity, which is often overlooked in pollution prevention and control frameworks. Rising global temperatures, altered precipitation regimes, land-use change, and intensified abstraction patterns modify recharge processes, flow paths, and contaminant transport mechanisms across environmental landscapes. This …

A Review of Locking Protocols for Concurrency Control in Parallel Databases
Abstract: In modern database systems, many transactions may run at the same time. When several users try to access the same data or update the data simultaneously, then it creates a problem such as inconsistency data, lost updates or misinformation and may lead to conflicts between the transactions and deadlocks. To avoid these types of issues and maintain the correctness of the database, concurrency control protocols are mainly used. This paper …

Anti-synchronization of Vallis System using Sliding Mode Control
Abstract: This paper is concerned with anti-synchronization of Vallis system (talks about fluctuations of temperature in western and eastern parts of near-equatorial area of the ocean). Sliding mode control is proposed to achieve the proposed anti-synchronization. A proportional integral switching surface is devised with appropriate control law and reduction of chattering is considered as well. Simulation results are given for verification and effectiveness of the proposed scheme. Simulation results reveal that …

Implementation of Adaptive Control Braking System for Collision-free Driving on Virtual Instrumentation Platform
Abstract: An unaccustomed driver not always has a sound judgment of the surrounding traffic and frequently depresses the brake pedal, causing a poor, jerky drive. Hence, nowadays in high-end cars to provide comfort to passengers while applying sudden brakes without jerks and also in time to avoid collision the adaptive control braking system is used. The main objective of this research study is to automatically monitor the braking force required to …
