Thesis

Master:

  • Title:  A Study on Optimization of Discriminant Spatial-Spectral-Temporal Feature for Classification of Imagination Movements using Brain Signal.
  • Adviser:Prof. Kwee-Bo Sim,Chung-Ang University, Seoul, South Korea
  • Description: This thesis explored two main problems in electroencephalographic (EEG) signal pattern recognition. The first problem is related to pre-processing signal to improve automation effective signal information using temporal-spatial-spectral subject independent information exploration using genetic algorithm. Second proposed problem is related to feature extraction of EEG pattern. In this part, I compared several new proposed feature extraction techniques to the previous research method. The result of analysis showed the improvement of effectiveness of proposed feature.

Bachelor:

  • Title: Realization of Trajectory Tracking Mobile Robot
  • Adviser: Dr. Ly Chek Keo, ITC, Phnom Penh, Cambodia
  • Description: This thesis was the result first robotic project in Institute of Technology of Cambodia. As a project leader of this project, I managed the team of four people to their specific tasks. I also took responsibility as the robot mechanical structure design and construction. Another part of my role was to design the electronic board for controlling system in robot and its communication system.
