Off topic : Congratulations Dr Joey/Rizal Nor!

One of our bloggers (he was actually the one who encouraged me to use LaTeX for writing) recently successfully defended his PhD dissertation at the Kent State University, Ohio, United States. And he’ll be coming back to Malaysia soon!!! (to my office, we’re in the same department).
Here is his thesis.. enjoy.
Congratulations again, Joey!
As far as I understood his thesis was written with LaTeX and use tikz package.. need him to verify this.
