  Numerical Analysis of the Effects of Flow Parameter on Magneto-convective Flow Past an Inclined Conductor

  Samson Odhiambo Juma, Simeon Kiprono Maritim

  The study of the effects of flow parameters on magneto-convective flow past an inclined conductor with a constant transversal magnetic field applied is considered. The governing momentum and energy equations are solved using a finite central scheme approximation, and the developing partial…

  A Performance Comparison of Machine Learning Models for Robotic Navigation Using Imbalanced and SMOTE-Enhanced Data

  Samiul Islam, Mynuddin, Sharmin Sultana, Somaresh Kumar Mondal, Abul Hossain, Gowranga Kumar Paul, Ayub Ali, Ayub Ali

  Robotic navigation systems rely heavily on accurate classification of sensor inputs to make real-time movement decisions. However, class imbalance—where certain navigation commands are underrepresented—can severely degrade the performance of machine learning models, particularly in safety-critical…
