Speech Title: Mathematical models for estimating the risk of epidemic outbreaks
Abstract: In recent years, it has been sometimes observed the phenomenon of epidemic outbreaks, which include SARS (Severe Acute Respiratory Syndrome), Ebola virus diseases, dengue fever, MERS (Middle East Respiratory Syndrome), and so on. Once the outbreaks occurs, the impact will be tremendous worldwide, partly because of the modern globalization. In this talk, we consider mathematical models for estimating a possible risk of epidemic bursts. The risk we consider takes into account of the economic aspects, since economic activities will be suffered from such outbreaks. In this direction, the model is based on stochastic processes. For epidemic modelling, we recall many important achievements of mathematical biology, which originates in the seminal work by Kermack-McKendrick and their famous threshold theorem. Combining these ingredients effectively, we evaluate the risk for social institution of epidemic outbreaks.

Title: Ab initio study of phase stability in thin films
The ab initio theoretical approach based on density function theory (DFT) has become a widely used tool in the study of phase stability in thin films.  In this talk, I will give two examples of investigating the phase stability in thin films, which include a new deep ultraviolet semiconductor candidate ZnGa2O4 and texture transformation in Ag thin films.  Recently, zinc gallate (ZnGa2O4) materials have attracted much attention due to their transparent conductive properties in the near-ultraviolet region.   In this presentation, the transition from Zn-doped Ga8O12 to Zn8Ga16O32 formation will be discussed.  Furthermore, the strain-induced texture transformation from (111) to (100) of Ag thin film will also be calculated and compared by recent experimental evidences.  Our results can explain previous experimental observations of texture transformation in Ag thin films.


Prof. I-Ming Tang, King Mongkut's University of Technology, Thonburi (KMUTT), Thailand

Dr. I-MingTang was born in Chungking, China. His father was posted to the USA as a diplomat in 1944. He was educated from kindergarten to his Ph. D. degree in the States. In 1978, he married a Thai, Savetree Viliacihit. He moved to Thailand in 1974 and began to work in two departments in the Faculty of Science, Mahidol University; the Departments of Chemistry and of Physics & Mathematics. The then dean told him that his main duties were to motivate the Thai Ajarns to do research. He was appointed to that rank of Special Professor in the Department of physics & Mathematics on September 15, 1986 by HRH, the King.
For his Ph.D. Dr Tang work on the relativistic two body equation. As soon as he received his Ph.D. degree in 1969, he switched to the field of superconductivity, both theoretical and experimental. While visiting Thai-land in 1972 where he taught at Chulalongkorn U., he switched his research again, this time to magnetism. Dr. Tang tends to switch his field of research every five years, both in physics and applied mathematics. In 2004, the then dean at Faculty asked him to become head of the Capability Building Unit in Nanoscience & Nanotechnology being set up by the faculty. In 2008, The Thai government set up the Thailand Center of Excellence in Physics (THEP) and Prof. Tang became head of the nanoscience program in the Mahidol part of THEP which became the most productive unit in THEP with over 60 publications.
In 2012, Prof. Tang moved to the Faculty of Science, Kasetsart University to help them develop the Department of Material Science and to help his former students from Mahidol University working in the physics department of KU. In June of this year, Prof. Tang moved to King Mongkut's University of Technology, Thonburi (KMUTT) as a consultant to the Computational & Applied Science for Innovation Cluster (CLASSIC) in the Faculty of Science where he would work with the Theoretical and Computational Science (TaCS) center and the Interface Surface Characterization (ISC) laboratory.

Abstract: Dilute Magnetic Semiconductors (DMS) are obtained when a few of the non magnetic ions in a semi conductor (such as the III-V semiconductors) are replaced by magnetic transmission metal (TM) ions.  Examples of DMS are GaAs, InAs, GaP or GaN when doped with the TM element manganese Mn.  (Ga,Mn)As has a TC ~ 170 K, while (Ga,Mn)P and (Ga,Mn)N have TC’s of approximately 400 K and 940 K, respectively.  The ferromagnetic behavior is needed to split the electric current, which is composed of currents of spin up and spin down electrons.  The magnetic field will lower the energies of the spin down electrons and spin down electrons, thus splitting the electron current in currents of spin down electrons and of spin up electrons.  The energy gap of the semi conductor can be manipulated so as to filter out one of the components of total current and allow only currents of one spin direction to pass through.  This is needed in spintronics where information is not only contained in the charges stored but also in the spins of the electrons stored.
This study is concerned with another type of DMS’s.  Sundaresan et al., pointed out that magnetism was a universal feature of nanoparticles of otherwise nonmagnetic oxides such as TiO2, SnO2, ZnO, Al2O3 and In2O3.  Many of these oxides are also members of the II-VI group of semiconductors.  Peng et al., has shown that ferromagnetism in these oxides is induced by the defects in the structure.  Theoretical DFT calculations done on one of these nonmagnetic ions ZnO NPs, showed that the absent Zn site in the wurtzite structure of ZnO would created virtual energy levels about the vacant site into which the 2p electrons from the neighboring oxygen ion sites could occupy.  The spin polarized configurations of the two 2p orbitals of the oxygen ions have a lower energy than the non-polarized pair thus giving rise to a local magnetic moment.  The role of non magnetic ions substitution into the Zn sites is to stabilize the zinc vacancy, thus promoting the ferromagnetism of the doped ZnO NPs.  We have measured the change in the magnetizations as the non magnetic Sb, Al, Ag, Mg and Li ions are substituted into ZnO NPs grown by the hydrothermal method.   We find in general that the saturation magnetizations (expressed as emu/gm) increase as the amount of doping increases.

Speech Title: Investigation of phononic crystal beams using a fiber Bragg grating displacement sensing system

Abstract: A point-wise fiber Bragg grating (FBG) displacement sensing system is developed and employed it to investigate the dynamic behaviors of phononic crystal (PC) beams. With the FBG sensing system, the transmission and the defect modes of the imperfect PC beams are studied. By comparison with the band structures obtained by the transfer matrix method, the dispersion curves of the infinite PC beams and practical finite ones are compared. We further improve the point-wise FBG displacement sensing system by only using an FBG without any other demodulation techniques. The improved FBG sensing system is used to study the transient displacement responses of a cantilever PC beam subjected to impacts. Our experimental results indicate that the proposed FBG measurement technique is capable of measuring the dynamic behaviors, including transient responses of the PCs, with high sensitivity and accuracy.

Speech Title: A family of 2n-point binary non-stationary subdivision schemes
Abstract: In this paper, we present a novel algorithm to construct 2n-point (for any integer n ≥ 1) binary approximating subdivision scheme by using the Lagrange polynomial. The proposed algorithm can be consider as asymptotically equivalent to the non-stationary counter part of the 2-point and 4-point existing binary stationary approximating schemes, for different values of n. Comparison of the curvature and torsion plots of curves are also presented. Conclusively, the whole discussion is followed by examples.

Speech Title: Highly accurate pseudospectral approximation for nonlinear differential equations
Abstract: Highly accurate numerical solutions for time dependent partial differential equations have studied using various methods. Spectral accuracy in time is equally important as it is in space. Therefore, implementation of spectral collocation method in space and time is very interesting, challenging and requirement of current research due to its spectral accuracy. Hence, spectral collocation methods based on Chebyshev-Gauss-Labatto points in both direction will be presented in this paper. The methodology is simple and applicable for all kind of differential operators including nonlinear operators. To demonstrate the performance of the approach, numerical results for a set of standard problems will be presented. Comparison with exact solutions of the problems, if exists, and other authors results will be presented.
