The Academy administers the award on behalf of the Group of Eight Deans of Engineering and Associates and the Medal will be awarded at ATSE’s Oration Dinner on 25 November 2016 in Melbourne. The winner will receive the Batterham Medal and a cash prize of $5000. THE WINNER WILL BE AN ENGINEERING GRADUATE OF AN AUSTRALIAN UNIVERSITY, UNDER 40 AT 1 JANUARY 2016 AND WILL: 1. have demonstrated excellence, innovation and impact in a field of engineering; 2. be clearly acknowledged by peers for a signature contribution to engineering in the five years prior to his/her nomination; and 3. have advanced the standing of the engineering profession. The Batterham Medal recognises Professor Robin Batterham AO FREng FAA FTSE, an Australian science and technology leader who was Chief Scientist of Australia from 1999 to 2006, President of the Academy from 2007 to 2012 and is Kernot Professor of Engineering at the University of Melbourne.

How Nonequilibrium Thermodynamics Speaks to the Mystery of Life
CORE CONCEPTS How nonequilibrium thermodynamics speaks to the mystery of life CORE CONCEPTS Stephen Ornes, Science Writer In his 1944 book What is Life?, Austrian physicist Erwin Schrödinger argued that organisms stay alive pre- cisely by staving off equilibrium. “How does the living organism avoid decay?” he asks. “The obvious answer is: By eating, drinking, breathing and (in the case of plants) assimilating. The technical term is metabolism” (1). However, the second law of thermodynamics, and the tendency for an isolated system to increase in entropy, or disorder, comes into play. Schrödinger wrote that the very act of living is the perpetual effort to stave off disor- der for as long as we can manage; his examples show how living things do that at the macroscopic level by taking in free energy from the environment. For example, people release heat into their surroundings but avoid running out of energy by consuming food. The ultimate source of “negative entropy” on Earth, wrote Schrödinger, is the Sun. Recent studies suggest something similar is hap- pening at the microscopic level as well, as many cellular processes—ranging from gene transcription to intracellular transport—have underlying nonequi- librium drivers (2, 3). Indeed, physicists have found that nonequilibrium systems surround us. “Most of the world around us is in this situation,” says theoretical physicist Michael Cross at the California Institute of Technology, in Pasa- Attributes of living organisms, such as the flapping hair-like flagella of these single- dena. Cross is among many theorists who spent de- celled green algae known as Chlamydomonas, are providing insights into the cades chasing a general theory of nonequilibrium thermodynamics of nonequilibrium systems. -

Fluctuation Theorem and Central Limit Theorem for the Time-Reversible Nonequilibrium Baker Map William Graham Hoover Ruby Valley Research Institute Highway Contract 60, Box 601 Ruby Valley, NV 8983 (Dated: February 13, 2018) Abstract The nonequilibrium Time-Reversible Baker Map provides simple illustrations of the Fluctua- tion Theorem, the Central Limit Theorem, and the Biased Random Walk. This is material in preparation for the Book form of Carol’s and my 2016 Kharagpur Lectures. Comments welcome. Keywords: Fluctuation Theorem, Chaos, Lyapunov Exponents, Irreversibility, Second Law, Baker Map arXiv:1708.03422v2 [cond-mat.stat-mech] 14 Aug 2017 1 I. INTRODUCTION In 1993 Denis Evans, Eddie Cohen, and Gary Morriss discovered an interesting symmetry, by now “well-known”, in their studies of the periodic shear flow of 56 hard disks1. They kept track of the time-averaged Gibbs’ entropy changes associated with the flow as a function of the averaging time τ. At a strainrateǫ ˙ and over a time window τ the distribution of entropy 2 production rates approaches a smooth curve with a mean value, h (S/k˙ )=(V/T )ηǫ˙ iτ . The fluctuations about this mean necessarily satisfy the Central Limit Theorem for large τ. Evans, Cohen, and Morriss stressed that both positive and negative values of the entropy production can be observed if the system is not too small ( 56 soft disks in their case ) and τ is not too large ( a few collision times ). At equilibrium the positive and negative values even out over time. Away from equilibrium the positive values win out. The relatively few time intervals with negative values correspond to periods of entropy decrease. -
Introduction
Securing Australia's Future By Simon Torok and Paul Holper, 208pp, CSIRO Publishing, 2017 Introduction We can’t know the future, we can’t predict it with great certainty, but we ought to know it’s going to be different, so we may as well think as constructively as we can about how to make it better. – Ian Chubb, launch of SAF08 Delivering Sustainable Urban Mobility, 7 October 2015 An evidence-based approach to informing policy Early in the second decade of the 21st century, the Australian Government recognised that a rapidly evolving global environment presents both opportunities and challenges. The Government engaged the Australian Council of Learned Academies (ACOLA) to under- take a series of detailed interdisciplinary national and international assessments to help guide Australian thinking and policy decisions. ACOLA, an independent organisation that links more than 2000 of Australia’s most eminent academics to support evidence-based interdisciplinary research, harnessed the expertise from across the country’s academies. This included many of Australia’s most influential leaders in the humanities, arts and social sciences (HASS) and science, technol- ogy, engineering and mathematics (STEM) domains. They did extensive research and, based on extensive evidence, compiled a series of well-supported findings designed to encourage Australia to be creative and innovative, adaptable and resilient. The ultimate objective of the work is ‘to secure the country’s future’. The scope of the SAF project was limited by the commission agreed between the gov- ernment of the day and the Office of the Chief Scientist. There was no suggestion that the project would examine every major challenge facing Australia, so, for example, there was no specific report that examined health policy, nor the implications of Australia’s demo- graphic changes such as increased life expectancy. -

Simulation of Two- and Three-Dimensional Dense-Fluid Shear Flows via Nonequilibrium Molecular Dynamics. Comparison of Time-and-Space-Averaged Stresses from Homogeneous Doll’s and Sllod Shear Algorithms with those from Boundary-Driven Shear. Wm. G. Hoover and Carol G. Hoover Ruby Valley Research Institute Highway Contract 60, Box 598, Ruby Valley 89833, NV USA Janka Petravic Complex Systems in Biology Group Centre for Vascular Research The University of New South Wales Sydney NSW 2052, Australia (Dated: November 6, 2018) Abstract Homogeneous shear flows (with constant strainrate dvx/dy) are generated with the Doll’s and Sllod algorithms and compared to corresponding inhomogeneous boundary-driven flows. We use one-, two-, and three-dimensional smooth-particle weight functions for computing instantaneous spatial averages. The nonlinear normal stress differences are small, but significant, in both two and three space dimensions. In homogeneous systems the sign and magnitude of the shear- arXiv:0805.1490v2 [nlin.CD] 19 Jul 2008 plane stress difference, Pxx − Pyy, depend on both the thermostat type and the chosen shearflow algorithm. The Doll’s and Sllod algorithms predict opposite signs for this normal stress differ- ence, with the Sllod approach definitely wrong, but somewhat closer to the (boundary-driven) truth. Neither of the homogeneous shear algorithms predicts the correct ordering of the kinetic temperatures: Txx > Tzz > Tyy.

INTRODUCTION In the present work, we use nonequilibrium molecular dynamics[1] to study microscopic simulations of “simple shear flow” (also called “plane Couette flow”): vx ∝ y → Pxy ≡ Pyx ≡ −η[(∂vx/∂y)+(∂vy/∂x)] = −η(dvx/dy) = −ηǫ˙ . -
