Using interpolation method to develop: A graphical user interface (GUI) to control and display 3D human body with smooth contour
(International University HCMC, Vietnam, 2011)
In this thesis, I developed a GUI to display human body in 3D. Initially, I extracted the data of each tissue or a group of tissues from the Visible Human Database, provided by REMCOM Inc. The extracted data was in ...
Audio watermarking implemented in DSP KIT TMS320C5510
(International University HCMC, Vietnam, 2009)
Digital audio watermarking is a technique developed to help in copyright protection of audio files. The research in this area has been spurred by the growth of the Internet, and the ease of copying audio material. This has ...
A study on PAPR reduction method for OFDM systems
(International University HCMC, Vietnam, 2009)
The Orthogonal Frequency Division Multiplexing (OFDM) has been used in many different wireless communication standards due to its many advantages. However, it has two major drawbacks, which are high peak-to-average power ...
Embedded system for IP application
(International University HCMC, Vietnam, 2009)
In this project, I have to learn and research the AVR control, internet protocol chip 28J60, and transfers data chip and 28j60 internet, standard interface chip 28j60 crabs and control. The research activities include ...
An investigation on radiation characteristics of helical antennas
(International University HCMC, Vietnam, 2009)
The Integral Equation (IE) method is used for analyzing the characteristics of the antenna
based on the current distribution on the antenna. IE with the unknown of current
distribution is solved by using numerical method ...
