this graduation thesis, I would like to thank the teachers at Faculty of Economics, Ho Chi Minh City University of Technology and Education. With the knowledge during the time I learned at school, I have a basic knowledge of the concepts and general contents so that I could complete this thesis. In particular, contributing to the process of developing this graduation thesis and giving dedicated instructions in the process, I would like to thank Mr. Huynh Anh Tuan – advisor for my graduation thesis.
He arranged the time to guide as well as give advice that contributed greatly not only to my graduation thesis, but also to my understanding and knowledge enhancement later on my career path. In addition, I would like to thank the enthusiastic support and guidance of the engineers in the TEF department in general and the TEF 3.3 team in particular. During my internship at Bosch Vietnam, it gave me the opportunity to learn and expand my knowledge, as well as improve and understand some of my hard skills and experience in a professional environment, which is with full of creativity and dynamism. This is a great opportunity for me to both touch reality and re-evaluate the knowledge I have learned at school and understand how that knowledge is applied in practice.
The thesis still has limited expertise as well as practical experience, so it is difficult to avoid errors in the article. In order for the essay to be more complete, I look forward to the comments and guidance from the teachers so that I have the opportunity to improve and develop my thesis in the future.
