From: Toby Driscoll driscoll@udel.edu
Date: January 31, 2025
Subject: New online book, Fundamentals of Numerical Computation
My textbook co-authored with Rich Braun, Fundamentals of Numerical
Computation, is now freely available online at
https://fncbook.com. Some key features:
- suitable for a single course or two-course sequence for
undergraduates
- 235 examples, 169 of which are presented with code in Julia, MATLAB,
and Python
- illustrative functions available in all three languages
- hundreds of exercises, each marked as written/computing
- animations of PDE solutions (all with generating codes)
- internal links, hover previews, glossary, index, and full-text
search
- online form for error reporting
The MATLAB and Julia versions are still available in print from the
SIAM bookstore, although the presentation of LU factorization switched
from Gaussian elimination to outer products after the MATLAB edition.

Subject: Course, Turbulence in Environmental Flows, Italy, Feb-March 2025
We offer a 3-week course on Turbulence in Environmental Flows
(abstract below) organized by the Department of Civil, Environmental
and Mechanical Engineering (https://www.dicam.unitn.it/en) of the
University of Trento, Italy, from February, 24th to March, 14th 2025.
Participation is open to MSc and PhD students, young researchers and
practitioners. The course can be attended on site or online for a
total duration of 60 hours (including hands-on tutorials),
corresponding to 6 ECTS for MSc students. A small fee (216 Euro) is
required for the registration, which closes on 16/02/2025.
The relevant information can be found in the course's website
https://sites.google.com/unitn.it/turbulence-env-flows
but do not hesitate to contact us for specific requests.
Turbulence in environmental flows
Abstract. Turbulence is one of the last mysteries, not yet fully
understood, in nonlinear fluid mechanics (including multiphase
flows). In this course, we provide an introduction to turbulence by
coupling the analysis of the most used numerical models (e.g.,
k-epsilon model) and the interpretation of real-world measurements,
with a special focus on processes occurring in the atmosphere and in
stratified water bodies such as lakes. The course covers theoretical
and numerical aspects of turbulence modelling and introduces the
necessary statistical tools for the analysis of data from turbulence
observations both in the field and in the laboratory. Theoretical
aspects are supported by numerous hands-on tutorials.

Subject: Feb 6 early registration and hotel for SIAM CSE, Mar 2025
Dear colleagues!
February 6 is the deadline for the early registration to and hotel reservation
for the SIAM Conference on Computational Science and Engineering
(CSE25), March 3–7, 2025 in Fort Worth, Texas.
Please register at:
https://siam.org/conferences-events/siam-conferences/cse25/registration/
Computational Science and Engineering (CSE) complements theory and
experiment as a critical component of scientific discovery. CSE is
indispensable for leading-edge investigation and engineering design in a vast
number of industrial sectors that all rely increasingly on advanced modeling
and simulation. CSE also contributes to policy and decisions relating to
human health, resources, transportation, and defense.
CSE is naturally interdisciplinary. Its goals concern understanding and
analyzing complex systems, predicting their behavior, and optimizing
processes and designs. CSE blends applications, computer architecture and
software, and algorithms. Current CSE challenges include the safe
deployment, explainability, and theoretical understanding of AI; the analysis,
visualization, and assimilation of large and complex data sets; and the design
of scalable, flexible, open, and robust CSE software.

Subject: Online training Core Imaging Library, March 2025
We’re hosting 3 online training sessions, where you can dive into the
Core Imaging Library (CIL) - a python package for tomographic imaging
and other inverse problems. Sessions are hands-on using Jupyter
notebooks and Python on our cloud platform, no installation needed.
Day 1 - 25 March, 13-17 GMT: Getting started with CIL
Day 2 - 26 March, 13-17 GMT: Iterative reconstruction with CIL
Day 3 - 27 March, 13-17 GMT: Advanced topics in CIL
This training is ideal for students and researchers working with CT
data or inverse problems. Whether you're conducting research,
building algorithms, or analysing imaging data, this is your chance
to enhance your skills.
You’re welcome to join one or all of the sessions, but if you’re new
to CIL or CT, we recommend kicking off with Day 1 to get familiar
with the basics. If you have been to one of our CIL trainings before,
Day 3 has some new notebooks and content to check out!
There are limited places available, so fill in the registration form
as soon as possible!
More details and sign-up (free of charge but mandatory) at
https://ccpi.ac.uk/events/cil-online-training-march-2025/
Post event (and in general) support is available on our Discord:

AMS MRCs are a professional development opportunity for up to 40
early-career researchers focused on a research domain. This AMS MRC
is focused on algorithms for numerically computing and manipulating
real solution sets to systems of polynomial equations and various
applications such as robot kinematics, computer vision, and chemical
equilibrium.
See https://www.ams.org/mrc-25 for more information including a
webinar discussing logistics and possible research projects.

Subject: Summer school on Numerical Analysis of PDEs, Optimisation and Uncertainty Quantification, June 2025
We are excited to invite you to the Numerical Analysis of PDEs,
Optimisation and Uncertainty Quantification summer school, hosted by
the University of Edinburgh, from 17th to 20th June 2025. As the
Biennial Numerical Analysis Conference is taking place from 24th to
27th June 2025 at the University of Strathclyde in Glasgow, one of our
goals is to equip participants, especially those attending the
conference, with the foundational knowledge needed to engage fully
with its content. As such, the summer school will feature four topics:
data assimilation, high-dimensional PDEs, scientific machine learning
and PDE constrained optimisation. Links for registration and travel
support will be available soon. We look forward to welcoming you to
Edinburgh!
