Abstract :
Considering the mechanism of quorum sensing, we formulate a bacteria-immunity model to describe the competition between bacteria and immune cells on the basis of Zhang's model (see Zhang et al. 2008, to appear, for more details). A distributed delay is introduced to characterize the time in which bacteria receive signal molecules and then combat with immune cells. We analyze the stability of the equilibrium points and discuss the existence of Hopf bifurcation near the positive equilibrium point. Finally, numerical simulation is carried out to illustrate our qualitative results. © 2008 Korean Society for Computational and Applied Mathematics.

Abstract :
The Iterative Closest Point (ICP) algorithm is an accurate and fast approach for registration between two point sets in a same scale, but it doesn't handle the case with different scales. This paper instead introduces a novel approach named the Iterative Closest Point with Bounded Scale (ICPBS) algorithm which integrates a scale with boundaries into the traditional ICP algorithm. This proposed technique uses the singular value decomposition algorithm and the properties of parabola to compute the similar transformation at each iterative step, and yields more satisfying robust results than the traditional ICP method in registration between two m-D point sets with different scales. Experimental results demonstrate the presented method is robust and fast for practical use. ©2007 IEEE.
