Asymptotic Behavior of Arithmetic Functions
 

Teo Lee Peng (funded by XMUMRF)

In analytic number theory, estimating the asymptotic behavior of arithmetic functions is an important topic. Despite being classical, the research in improving the estimates in the error terms of the prime number theorem and the Siegel-Walfisztheorem has never stopped. Usually, some auxiliary functions and parameters are used. We plan to employ some optimization method to choose the auxiliary function and parameters.   

 

Adaptive Mesh-Free Wavelet-Based Collocation Method for the Coupled Analysis of Thermal-Magneto-Electro-Elastic Plates

Liew Siaw Ching, Liu MeiFeng (funded by XMUMRF)

In this research, an adaptive meshless simulation for the coupled analysis of Thermo-magneto-electro-elastic (TMEE) plate based on wavelet multiscale resolution and radial basis (RBF) collocation will be presented. Nonlinear governing equations for the thermo-magneto-electro-elastic (TMEE) plate subjected to coupling applied load will be derived under the consideration of finite strain deformation, and then meshless method will be adopted to take over the tasks for static behaviour or dynamical response of the invented mathematical model. The adaptive element-free wavelet method (AEFWM) will be developed in this research project by using two-scale Daubechies wavelets in accordance with the radical basis collocation function. Node adaption will be implemented according to the tendency of wavelet coefficients, additional nodes will be added on the neighbourhood of active node point, the adaptive criterion and node refinement scheme for the AEFWM will be discussed in detail. The proposed numerical method can be used to find out the solution for the partial differential equations aroused in the coupled TMEE plate due to crack, shock wave, moving boundary conditions or nonlinear applied load etc.
