Modeling and experimental validation of an indirect active hybrid solar dryer for mint leaves: Coupled thermal and moisture-transfer analysis

A mathematical model was developed and experimentally validated to predict the thermal performance and drying behavior of an indirect active solar dryer (IAHSD) for mint leaves. The distinctive contribution of the proposed approach is its integration of solar-energy input, auxili...

Enhanced FOC performance using a hysteresis current controller for EV induction motor drives

Electric vehicle traction drives require fast, robust, and efficient induction motor control, especially under variable speed, load torque, and thermal operating conditions. In Field-Oriented Control integrated Hysteresis Current Controller (FOC-HCC) induction motor drives, varia...

Recent Advances in Microalgae‐Based Functional Coatings and Films for Food Packaging Applications: Opportunities and Challenges

ABSTRACT The increased popularity of sustainable food packaging and its technologies has led to considerable interest in microalgae‐derived functional films and coatings as potential replacements for traditional plastics based on petroleum. The literature in recent years has been...

Efficient Feature Selection with Multiple Equivalent Subsets Using a Multi-objective Quantum-inspired Evolutionary Approach

Abstract In many real-world applications, it is useful to identify multiple distinct feature subsets that achieve the same classification accuracy with the same number of features. This gives domain experts more flexibility to choose feature combinations based on cost, availabili...

Benchmarking one-class and binary classifiers for weld defect detection using acoustic emission signals

The aim of this study is to apply diagnostic techniques to welds based on machine learning methods. This approach works exclusively with signal data, making it nondestructive and enabling easier and faster implementation. It detects anomalies immediately after the welding procedu...

Thermal and mechanical behaviour of high-performance concrete incorporating recycled concrete aggregate

The construction industry contributes substantially to environmental problems through the extraction of non-renewable resources and the generation of construction and demolition waste. In concrete production, replacing natural aggregate with recycled concrete aggregate (RCA) has...

Martian‑Regolith Simulant Confined Nanogenerators for Wireless Tactile Sensing for Human‐Machine Interface

Achieving a sustainable energy system for space missions remains challenging due to the continued reliance on Earth-supplied materials. This underscores the importance of in situ resource utilization (ISRU) strategies that convert planetary resources into functional electronic co...
