A combinatorial approach to the power of 2 in the number of involutions (2009)
We provide a combinatorial approach to the largest power of $p$ in the number of permutations $\pi$ with $\pi^p=1$, for a fixed prime number $p$. With this approach, we find the largest power of 2 in...

Automatic Edge Detection Method for Mobile Robot Application (2008)
Kim, Dongsu, Kweon, Inso, Lee, Wangheon
This paper proposes a new edge detection method using a $3{\times}3$ ideal binary pattern and lookup table (LUT) for the mobile robot localization without any parameter adjustments. We take the mean...
On a continued fraction formula of Wall (2007)
Dongsu Kim, Jiang Zeng, Mourad Ismail
. We study the combinatorics of a continued fraction formula due to Wall. We also derive the orthogonality of little q-Jacobi polynomials from this formula, as Wall did for little q-Laguerre...
