Numerical Study of the Transition Metal Oxides and the Transport Properties of Iron Pnictides

Strongly correlated materials such as the manganites and iron pnictides are studied here with several computational techniques. Both types of materials contain transition metals. Thus, our computational models are based on the double exchange mechanism, the super exchange mechanism and the crystal field theory to describe the d electrons. In manganites, we focus on its multiferroic properties induced by the Dzyaloshinskii-Moriya interaction. In the BiFeO3 , we use classical Monte Carlo simulations to study the magnetic critical transition transition. In iron pnictides, we study the interplay between the Fermi surface orbital order and the ground state magnetic order

Biological Subtle Motion Magnification Based on 3D Wavelet Transform

This paper presents an amplification algorithm of subtle motion which reveals important aspects of the world. Our analysis is based on spatial and temporal projection of decomposition of the viewpoint video by using 3D wavelet transform, which is used to estimate the optimal scale and threshold function in order to extract the interested region. We discuss parameters of effect and estimate the threshold function by employing integral energy and maximum values of pixels. The results of the subtle motion magnification by using the optimal scale and threshold function have a good effec
