Magnetoacoustic Tomography with Magnetic Induction (MAT-MI) is a hybrid magnetic modality aiming to reconstruct the electrical impedance property in biological tissue by integrating magnetic induction and ultrasound measurements with high resolution. Most of the existing computation algorithms for MAT-MI are based on the assumption that the tissue has homogeneous acoustic properties. However, the...
Range image registration is a popular problem in pattern recognition and computer vision, and it has a wide range of applications in real life. The objective of registration is to match two models as close as possible. In this area, the best known iterative closest point (ICP) method is sensitive to the initial position of two models and it is easy stuck in local minima. In recent years, heuristic...
The effect of aggregated parasitoid on a host-parasitoid system are investigated qualitatively by computer simulation. Our numerical simulations show that the aggregation of parasitoid can stabilize the population dynamics when the density-dependent effects of host is weak, while it can also destabilize the system when the density-dependent effect of host is strong. A variety of complex population...
