The classification of coffee bean roast levels using Agtron standards has evolved from traditional subjective methods to technology-driven approaches employing advanced artificial intelligence. Recent advancements in computer vision have demonstrated…

This document describes the implementation and evaluation of a retrieval-augmented generation (RAG) system to improve access to and understanding of Moroccan law, particularly the family code in Arabic. The research addresses the drawbacks of the…

Owing to the demand for frequency agility, a switchable ultra-wideband (UWB) hexagonal antenna was developed in this study. The proposed antenna features two notch filters introduced by two U-shaped slots on the patch to reduce interference from…

An super-twisting algorithm (STA)-based controller was designed and implemented in this study to achieve precise control over the stator active and reactive power of a doubly fed induction generator (DFIG)-equipped wind turbine device. The fractional…

With the rapid growth of the population, the demand for autonomous video
surveillance systems has substantially increased. Recently, artificial intelligence
has played a key role in the development of these systems. In this paper, we
present an…

The encryption of medical images protects the privacy of patient information transmitted over networks and communications. In this paper, a lightweight encryption method for medical images is proposed, combining a quadtree-based segmentation and a…

Speech signal analysis aims to identify patterns within data to develop effective
recognition algorithms. This process primarily utilizes feature extraction
techniques such as linear predictive coding (LPC), linear predictive cepstral…

Wireless sensor networks (WSNs) comprise large numbers of sensor nodes that
are highly constrained by limited battery power, making energy-efficient routing
essential for sustaining network lifetime and service quality. Among existing
solutions,…

Chronic autoimmune gastritis (CAG) is a condition in which the stomach membrane is significantly impacted by inflammation. Despite the availability of numerous modern medical techniques, the detection of this condition continues to be a difficult…

This work presents a novel compact four-port multiple-in multiple-out (MIMO) antenna enhanced with metamaterial unit cells for 5G millimeter-wave (mmWave) applications at 28 and 38 GHz. Compact MIMO antennas at mmWave bands often suffer from high…
