Comparative Analysis of MCNN and RCNN for Speech Emotion Recognition Using Gender Information
Abstract: Speech emotion recognition is a speech processing task and a computer-based approach designed to identify and classify the emotions conveyed in audio signals. The aim of this system is to evaluate a speaker's emotional state, such as happiness, anger, sadness, or frustration, by analyzing their speech patterns, which include prosodic features like pitch, frequency, and rhythm. Speech emotion recognition is used in various real-life scenarios that include Customer Service, Healthcare, …

IoT-based Marine Life Tracking and Pollution Monitoring System
Abstract: In the contemporary world, marine pollution stands as a significant challenge that has adversely affected oceans over the decades. This issue has been exacerbated by human activities, including the improper disposal of sludge, oil spills, and agricultural runoff entering marine environments without adequate regulatory oversight. The repercussions of ocean pollution are detrimental, impacting marine ecosystems, the environment, and ultimately human health. The Internet of Things (IoT) has emerged as a …

Quad-Band Notched Small Monopole Antenna with U-shaped Slots and SRRs for UWB Applications
Abstract: A quad-band notched small monopole antenna with U-shaped slots and SRRs for UWB applications is presented in this study. The quadruple band-notched characteristics can be achieved by embedding three U-shaped slots on the radiation patch and two split ring resonators (SRRs) near feed line, respectively. It has a tiny size, only 17 mm23 mm0.508 mm. The experimental and measured results demonstrate that the proposed antenna offers an impedance bandwidth across …

Advanced 4-Element UWB-MIMO Antenna Design: Achieving High Isolation and Multi-Band Rejection for Advanced Wireless Applications
Abstract: In this study, we present the design, fabrication, and analysis of a step-by-step Ultra-Wideband (UWB) Multi-Input Multi-Output (MIMO) antenna operating from 3 to 14 GHz. The antenna consists of four elements, each characterized by high isolation and equipped with four band-rejection features. These elements are implemented on a Rogers substrate with εr=3. Each antenna element is a modified rectangular patch, incorporating partial ground etching to achieve wider bandwidth. Two sets …
