Optimization of Hybrid Machine Learning Approach for Unemployment Rate Forecasting

Applied Computational Intelligence and Soft Computing, Volume 2025, Issue 1, 2025.
This research proposes a robust approach for forecasting female unemployment rates across various regions in Egypt using optimized support vector machines (SVMs). Key factors such as education level, age, and location are analyzed to enhance prediction accuracy. The process involves three phases: training, predicting, and optimizing.

A Novel Improved Beluga Whale Optimization Algorithm for Solving Localization Problem in Swarm Robotic Systems

CoRR
In Swarm Robotic Systems (SRSs), only a few robots are equipped with Global Positioning System (GPS) devices, known as anchors. A challenge lies in inferring the positions of other unknown robots based on the positions of anchors. Existing solutions estimate their positions using distance measurements between unknown robots and anchors.

Utility‐scale solar photovoltaic power plant emulating a virtual synchronous generator with simultaneous frequency and voltage control provision

IET Energy Systems Integration, Volume 6, Issue 4, Page 386-405, December 2024.
Abstract Network operators with significant solar photovoltaic (PV) penetration are having difficulty maintaining grid frequency and voltage within acceptable bounds due to the progressive displacement of synchronous machines. Utility‐scale solar PV plants have a huge potential for participation in frequency and voltage regulation since they are linked
