Mode division multiplexing using Laguerre–Gaussian beams with VSB-CSRZ modulation for high-capacity underwater optical wireless communication

Abstract Underwater optical wireless communication (UOWC) is a promising technology for high-speed data transmission underwater due to its large bandwidth, low latency, and high capacity. In this work, a high-capacity UOWC system based on mode division multiplexing (MDM) and vest...

Optimization of Co-Cr Alloys Fabricated by DMLS Using Multi-Objective Grey Relational Analysis

Objectives: To optimize Direct Metal Laser Sintering (DMLS) parameters for Co-Cr alloys to simultaneously enhance microhardness and compressive strength using multi-objective Grey Relational Analysis (GRA). Method: Co-Cr alloy specimens were fabricated using DMLS by varying laser...

Multi-level poultry disease detection from fecal images using jellyfish search honey badger optimization and deep learning in IoT frameworks

Poultry is a major source of food, and growing demand for animal-based products has driven agricultural industries to increase production. However, this expansion has also led to a significant rise in the spread of infectious diseases. Several limitations faced by conventional me...

An improved Portia spider optimized SpikeApneaNet for ECG-based sleep apnea detection with FPGA implementation

Sleep apnea (SA) is a serious sleep disorder that is characterized by recurrent episodes of breathing cessation, resulting in oxygen desaturation, interrupted sleep and increased risk of cardiovascular diseases, including hypertension, stroke, and arrhythmia. Early detection is c...
