HybOptic-CNN: A hybrid WOA-GWO-optimized convolutional neural network model for enhanced plant disease detection in the Nigerian environment

Plant diseases threaten agricultural productivity, and automated image analysis can support early identification of visible disease symptoms. This study introduces HybOptic-CNN, a convolutional neural network (CNN) whose learning rate and batch size are selected using a hybrid Whale Optimization Algorithm--Grey Wolf Op...

Finite Element-Informed Tunable Control for Robust Vibration Mitigation in Flexible 3D of Robotic Arm

This study presents the dynamic modeling and control of a clamped-free beam system using Proportional–Integral–Derivative (PID) control strategies, with a focus on comparing the performance of a Standard PID controller and an optimally Tuned PID controller. Flexible beam structures are widely used in robotic and precis...

Mathematical Modeling and Multi Loop Control for 6-DOF 25kg Digital Servo Educational Desktop Robotic Arm V2

This study presents the mathematical modeling and control of a 6-DOF 25 kg Digital Servo Educational Desktop Robotic Arm using a multi-loop control framework based on conventional PID and Particle Swarm Optimization (PSO)-tuned PID controllers. The robotic system was modeled as a nonlinear, coupled dynamic system incor...
