HSE: Chemicals and Gases

This week Phil Collins will present on “HSE: Chemicals and Gases“.

……………………………………………….

​​Lunch and learn – 14th Aug (Topic – HSE)

​ Hello all,

As part of the HSE Plan 25-27 and our values of ‘Further Together’ the CSIRO HSE ‘Grassroots Campaign’ has a focus on HSE Procedure Awareness.

The HSE Team is working together to develop the information for these sessions which will be delivered by the HSE Manager from each RU. This invitation is open to all Space and Astronomy.

The sessions themselves will be an overview of the procedure, followed by discussion and opportunity for questions.

To get the most from attending the session read the procedure prior to attending – Hazardous Chemicals and Gases Procedure – MyCSIRO

Subject Matter Experts will be in the sessions or provide content (where relevant and available) to add specific insight into the discussions.

​Any questions please contact Phil Collins (HSE Manager – S&A)

Colearnium: David Skellern
2025-09-11 12:00 - 12:30
A commentary on who really ‘invented Wi-Fi’

This week David Skellern will present on “A commentary on who really ‘invented Wi-Fi’“.

———————————————————————————————————————————————————–

Dr David Skellern, AO FTSE FIEEE HonFIEAust

Dr David Skellern worked in radio astronomy for 10 years and taught electronics at the University of Sydney and Macquarie Universities for 16 years before coming to prominence in the IT sector through Radiata, which he co-founded in 1997. Building on joint research at Macquarie University and CSIRO, Radiata demonstrated the world’s first chip-set implementation of the 54Mbit/s lEEE 802.11a high speed WLAN standard. Radiata was sold in 2001 to Cisco Systems Inc, where Dr Skellern was Director, Technology of the Wireless Networking Business Unit until 2004.

He was appointed to the Board of National ICT Australia in 2003 and was Chief Executive Officer 2005-2010.

He was a Non-executive Director (NED) of the Board of the Capital Markets CRC (CMCRC) 2004-2019 and Board Chair 2013-2019, then Chair of RoZetta Institute Ltd (formerly CMCRC) 2019-2022. He was also a NED of the Boards of eight RoZetta Group companies.

Dr Skellern is a NED and Board Chair of Quasar Satellite Technologies Pty Ltd, the Semiconductor Sector Service Bureau (S3B), and the International Centre for Radio Astronomy Research (ICRAR), and a NED of Trovio Pte Ltd. He advises several early-stage technology companies. He is a Visiting Professor at Imperial College London and an Adjunct Professor at Macquarie University.

Who Really Invented Wi-Fi?

In the early 1990s, a joint CSIRO/Macquarie University team conceived, developed and implemented the linked technologies that made it possible to scale wireless LANs to ever-higher speeds as chip technology advanced. This pioneering work shaped the global success of Wi-Fi.

A Sydney Morning Herald article on March 25 this year mixed valid concerns on science funding innovation with selective history and emphasis on disputes to downplay and reframe the originality and significance of these Australian achievements on high speed WiFi.

This talk sets the record straight, separating fact from myth, and showing how high-speed WiFi was truly born.

Colearnium: Duy Nguyen (CSIRO)
2025-11-06 12:00 - 12:30
A Single-Chip Wideband Digital Receiver for the Australia Telescope Compact Array Upgrade

This week Duy Nguyen will present on “Modernizing Legacy: Wrapping a 25+ Year Computational Fluid Dynamics Codebase“.

Modernizing Legacy: Wrapping a 25+ Year Computational Fluid Dynamics Codebase

Authors: Duy Nguyen, Tisham Dhar, Peter Wang, Jean-Michel Perraud, Klaus Joehnk.Computational Fluid Dynamics (CFD) is the science of using numerical analysis and data structures to solve many processes influencing fluid behavior. CFD requires many complex mathematical representations through various ODE and PDE solvers, and has traditionally been written in Fortran or C++, mostly for their speed in doing massively parallel computations, such as handling array operations and object-oriented features. As such, those codebases have a long-standing legacy in scientific computing, and many established CFD codes are written in them. However, as time goes on, we witness the popularity of a new generation of codebases such as Python, which stems from its simplicity, versatility, and strong community. Extensive libraries and frameworks make Python a popular choice for many developers and scientists alike. It is, however, not a preferred language for core CFD code due to performance limitations and its difficulties with parallelization. This talk explores modernizing a 25+ year-old C++ CFD model, essential for simulating lake conditions, particularly for predicting temperature variations and algal bloom dynamics, by wrapping it with [C-interop] for seamless Python interoperability. Beyond integration, we leverage [Optuna], a powerful hyperparameter optimization framework, to fine-tune models efficiently, transitioning from manual parameter tuning on a laptop to a distributed, scalable workflow powered by Dask Distributed and JupyterHub. This transformation enables automated hyperparameter optimization across many lakes in Australia, helping researchers investigate trends in tuning parameters and derive deeper environmental insights.Attendees will gain insights into:– Wrapping legacy C++ water quality models with CFFI for Python-driven analysis.– Automating and scaling hyperparameter tuning using Optuna across multiple lake ecosystems.– Utilizing Dask Distributed and JupyterHub to accelerate environmental simulations.– Extracting insights from hyperparameter trends to refine large-scale water quality predictions. For researchers, engineers, and data scientists working in environmental modeling, this session provides practical strategies for modernizing legacy systems, scaling model optimization, and enhancing predictive accuracy without sacrificing scientific integrity.

How CSIRO engages with government

This week Jack Steele will present on “How CSIRO engages with government“.

What are ‘Estimates’ and what is CSIRO’s role? How do we deal with ‘our’ Minister? What’s the latest on the Strategic Examination of R&D and the CSIRO parliamentary inquiry? What does it mean to say that CSIRO is part of government, and how does that affect our engagement with them?
