Huge congratulation to my PhD student, Fauzy Sulaiman who has completed his viva today. He registered as Master by research student at first and I encouraged him to convert to PhD. He managed to convert in his 2nd semester and submit his PhD thesis by 7th semester. Congratulation also to both co-supervisors, Prof. Datuk. Ir. Dr. Wahid Omar and Dr. Abdullah Zawawi Awang. Thanks for the constructive comments from External Examiner, Prof. Dr. Azmi Ibrahim (UITM Shah Alam) and Internal Examiner, PM. Dr. Arizu Sulaiman. Last but not least thanks to the session chairman Prof. Dr. Abd Latif Bin Saleh and Dr Azreen. Not to forget En. Jaya and Puan Aida from Faculty of Engineering for managing the online viva session.
