Mehiddin Al-Baali - Department of Mathematics and Statistics, Sultan Qaboos University, Muscat, Oman
Recently, we have extended the damped-technique in the modified BFGS method of Powell for constrained optimization to the Broyden family of quasi-Newton methods for unconstrained optimization....

Dr Sophie Calabretto - Macquarie University, Sydney
The detection, and forecasting, of ocean vortices is important in the field of geophysical fluid dynamics as these eddies tend to play a major role in the underlying flow dynamics of the ocean. We...

Dr Sung Yong Kim - Korean Advanced Institute for Science and Technology
This talk presents various aspects of coastal surface circulation based on multi-year observations of high-frequency radar-derived surface currents off the U.S. West coast.  The dynamics of the...

Craig Tracy - University of California - Davis
The asymmetric simple exclusion process (ASEP) is arguably the simplest generalization of simple walk on the integer lattice to interacting random walkers on the integer lattice. This lecture will...

Luc Vinet - Université de Montréal
The Bannai-Ito algebra and its relation to the Bannai-Ito polynomials will be reviewed.  Emphasis will be put on some of the connections with the Lie superalgebra $osp(1,2)$.  Centralizing elements...

Hsien-Kuei Hwang - Academia Sinica, Taipei
A class of recurrences of Eulerian type is examined from the viewpoint of asymptotic distribution of the coefficients. We characterize various limit laws of the coefficients using the method of...

Professor Herbert E Huppert FRS - Institute of Theoretical Physics, Cambridge
After a short introduction to the mechanism and politics of fracking, the talk will concentrate on the fluid mechanics and elastodynamics of driving fluid into cracks and the quite different...

Professor Hwa-Lung Yu - National Taiwan University
The rapid development and increase of low-cost sensors provide an unprecedented new way in understanding the space-time distribution of environmental quality. However, due to the relative low quality...

Bryce Kerr - University of New South Wales
This talk concerns some recent results joint with Igor Shparlinski and Kam Hung Yau regarding estimates for multiplicative character sums modulo a prime number. We review the Burgess bound for such...

Professor Timoteo Carletti - Namur Center for Complex Systems (naXys), Université de Namur
Spatially non-homogenous states (patterns) can spontaneously emerge in a multitude of Natural of human made systems. In many cases of interest, the interplay between nonlinearities and...
