Environmental Modelling for Better Predictions & Decisions

When: 

16-17 November, 2021

Conference / Workshop

Please join us for a symposium at QUT in September focused on 'Environmental modelling for better predictions and decisions'. We include all aspects of the environment -- including but not limited to ecology, populations, fisheries, agriculture, climate, weather. Likewise, our definition of modelling is broad -- anything with a maths, stats, or data science angle likely fits well.

CG versus MINRES in Non-linear Optimization

When: 

Tuesday 16 November, 12pm-1pm AEDT

Public talks

The celebrated conjugate gradient (CG) method is a very well-known and an indispensable method for solving linear systems involving positive definite matrices. CG has also been classically the dominant solver in most non-linear second-order methods for unconstrained optimization. In this talk, we consider replacing CG with a less known alternative, knows as the minimum residual method (MINRES), which is often used for symmetric but possibly indefinite linear systems.

ACEMS Virtual Public Lecture - Extreme Diffusion

When: 

Thursday, 4 November: 11 am AEDT,

ACEMS Seminar Series talk

Diffusion is pervasive in the natural world. Over one hundred years ago Einstein created a remarkably simple and powerful theory describing the behavior of a single diffusing particle. That theory has since been applied countless times to successfully model widely disparate systems. In this talk, Ivan will explain a failure of this theory when applied to systems with many particles diffusing in the same environment. In particular, in such systems, the particles that move the furthest (the extremes of the diffusion) are governed by behaviors much different than would follow from Einstein's theory.

ACEMS 2021: The Final Retreat

When: 

1 - 5 November

Conference / Workshop

The ACEMS Final Retreat is an opportunity for the ACEMS community to come together, celebrate and share the Centre's research and achievements in 2021 - the Centre’s final year, and it will also be an opportunity to discuss the legacy of the Centre.

ACEMS Virtual Public Lecture - Statistical Methodology Development and Software Dissemination

When: 

Thursday 28 October, 12pm-1pm AEDT

Public talks

Professor Matt Wand has been involved in statistical methodology research since the mid-1980s. During the second millennium, the internet either did not exist or was in its infancy and software dissemination was primitive. The advent of the internet and the establishment of websites such as the Comprehensive R Archive Network, which officially started February 2000 - have had a profound impact on applied and methodological statistics.

ACEMS Virtual Public Lecture - A Song of Wind & Fire: a statistical journey through an uncertain world

When: 

Wednesday 14 July, 12pm-1pm AEST

Public talks

In this free public lecture, ACEMS Associate Investigator Dr Rachael Quill will explore how shedding light on the uncertainties of wind flow across the environment can support informed decision-making in bushfire management and renewable energy generation.

Virtual Public Lecture featuring Dr Eugenia Cheng

When: 

Wednesday, 5 May, 12pm-1pm AEST

Public talks

As part of International Women in Mathematics Day in May, ACEMS is proud to present Dr Eugenia Cheng for a special Virtual Public Lecture. Dr Cheng has been featured in the New York Times, presented TED Talks, written several books, and even appeared on "The Late Show with Steven Colbert". In this lecture, Dr Cheng will show how we can use mathematical thinking to work towards a more inclusive society.
