SUMMARY:CARMA Seminar\n "Using cognitive modelling to better understand the heritability of cognition"\n Prof Scott Brown
LOCATION:V205, Mathematics Building
DESCRIPTION:CARMA Seminar\nV205, Mathematics Building\nCARMA Special Semester in Computation and Visualisation\n\n"Using cognitive modelling to better understand the heritability of cognition"\nProf Scott Brown\n\nAbstract:\nAn enduring topic of research interest relates to the heritability of mental traits, such as intelligence. Some of the work on this topic has focussed on genetic contributions to the speed of cognitive processing, by examination of response times in psychometric tests. An important limitation of previous work is the underlying assumption that variability in response times solely reflects variability in the speed of cognitive processing. This assumption has been problematic in other domains, due to the confounding effects of caution and motor execution speed on observed response times. We extend a cognitive model of decision-making to account for the relatedness structure in a twin study paradigm. This approach has the potential to separately quantify different contributions to the heritability of response time: contributions from cognitive processing speed, caution, and motor execution speed. In some ways, this is a typical usage of an evidence accumulation model, and it throws up all the typical problems that we struggle with in data visualisation. Those problems will become evident during the talk, as we discuss data from the Human Connectome Project. We find that caution is both highly heritable and highly influenced by the environment, while cognitive processing speed is moderately heritable with little environmental influence, and motor execution speed appears to have no strong influence from either. Our study suggests that the assumption made in previous studies of the heritability being within mental processing speed is incorrect, with response caution actually being the most heritable part of the decision process.

SUMMARY:CARMA Seminar\n "Methods of Experiment by Visualization in Research Mathematics"\n Scott Lindstrom
LOCATION:V205, Mathematics Building
DESCRIPTION:CARMA Seminar\nV205, Mathematics Building\nCARMA Special Semester in Computation and Visualisation\n\n"Methods of Experiment by Visualization in Research Mathematics"\nScott Lindstrom\n\nAbstract:\nExperimental discovery has long played an important role in research mathematics, even before the advent of modern computational tools. Many methods of antiquity are familiar to all of us, including the drawing of pictures to gain geometric insights and exhaustively solving similar problems in order to identify patterns. I will share a variety modern computational tools and techniques which I have used for my research at CARMA. The contexts of the discoveries will be varied -- including number theory, non-Euclidean geometry, complex analysis, and optimization -- and so the emphasis will be on the strategies employed rather than specific outcomes.\n\nBio: Scott Lindstrom received his master's degree from Portland State University. In September, 2015, he came to CARMA at University of Newcastle as a PhD student of Jonathan Borwein. Following Professor Borwein's untimely passing, he has continued as a student of Brailey Sims, Heinz Bauschke, and Bishnu Lamichhane. In October he will begin a postdoctoral fellowship at Hong Kong Polytechnic University. His principal research area is experimental mathematics with particular emphasis in optimization and nonlinear convex analysis. He is a member of the AustMS special interest group Mathematics of Computation and Optimization (MoCaO) and organizes the Borwein Meetings for RHD students and postdocs at CARMA.\n

SUMMARY:CARMA Seminar\n "Discrete Element Modelling in Geomechanics: Recent developments and ongoing challenges"\n Dr Klaus Thoeni
LOCATION:V205, Mathematics Building
DESCRIPTION:CARMA Seminar\nV205, Mathematics Building\nCARMA Special Semester in Computation and Visualisation\n\n"Discrete Element Modelling in Geomechanics: Recent developments and ongoing challenges"\nDr Klaus Thoeni\n\nAbstract:\nThe Discrete Element Method (DEM) is a very powerful numerical method for the simulation of unbonded and bonded granular materials, such as soil and rock. One of the unique features of this approach is that it explicitly considers the individual grains or particles and all their interactions. The DEM is an extension of the Molecular Dynamics (MD) approach. The motion of the particles is governed by Newton's second law and the rigid body dynamic equations are generally solved by applying an explicit time-stepping algorithm. Spherical particles are usually used, as this results in most efficient contact detection. Nevertheless, with the increase of computing power non-spherical particles are becoming more popular. In addition, great effort is made for coupling the method with other continuum methods to model multiphase materials. The talk discusses recent developments of the DEM in Geomechanics based on the open-source framework YADE and some of its ongoing challenges.\n \nBio: Klaus has more than 10 years' experience in the development of cutting-edge numerical tools for geotechnical engineering and rock mechanics applications. He obtained his PhD in civil engineering from Graz University of Technology (Austria). After moving to Australia, he expanded his initial research experience on continuum-based numerical modelling with the Boundary Element Method (BEM) and Finite Element Method (FEM) by taking on the Discrete Element Method (DEM), a discontinuum-based method. He is an active developer of the open-source DEM framework YADE (https://yade-dem.org), an efficient numerical tool for the dynamic simulation of geomaterials. Lately he has been concentrating on the development of a highly innovative framework for the modelling of deformable discrete elements.

SUMMARY:CARMA Colloquium\n "The Parallel Worlds of Number Theory"\n Prof. Florian Breuer
LOCATION:V205, Mathematics Building
DESCRIPTION:CARMA Colloquium\nV205, Mathematics Building\n"The Parallel Worlds of Number Theory"\nProf. Florian Breuer\n\nAbstract:\nThere is an intriguing analogy between number fields and function fields. If we view classical Number Theory as the study of the ring of integers and its extensions, then function field arithmetic is the study of the ring of polynomials over a finite field and its extensions. According to this analogy, most constructions and phenomena in classical Number Theory, ranging from the elementary theorems of Euler, Fermat and Wilson, to the Riemann Hypothesis, Elliptic curves, class field theory and modular forms all have their function field analogues. I will give a panoramic tour of some of these constructions and highlight their similarities and differences to their classical counterparts. \nThis lecture should be accessible to advanced undergraduate students.

SUMMARY:CARMA Colloquium\n "Quantization using random, Diophantine, and dynamical processes"\n Prof. Joseph Rosenblatt
LOCATION:V205, Mathematics Building
DESCRIPTION:CARMA Colloquium\nV205, Mathematics Building\n"Quantization using random, Diophantine, and dynamical processes"\nProf. Joseph Rosenblatt\n\nAbstract:\nThe use of various methods to obtain close to optimal quantization leads to interesting questions about the behavior of random processes, Diophantine approximation, ergodic maps, shrinking targets, and other related constructions. The goal in all of these approaches to quantization is the speed of decrease of the error, coupled with the simplicity and concreteness of the process employed.
