Subject: New Self-Paced Linear Algebra Course (Update)

In NA Digest, V. 19, # 48 we introduced a novel self-paced Linear
Algebra course where students learn by doing, at their own pace,
receiving real-time feedback from the NCLab platform. The instructor
does not lecture and works with each students individually
instead. The course is perfect for both in-person and online
instruction. NCLab's Python backend allows students to experiment in
real time with advanced computational applications of Linear Algebra
including Fourier series, best approximation, and data denoising and
image compression with SVD.

The course has been in use for three consecutive semesters now with
great success. Students consistently like the self-paced learning
model much more than traditional classroom teaching. Our findings are
summarized in the recent paper "Self-Paced, Instructor-Assisted
Approach to Teaching Linear Algebra"

The course has been continuously improved based on the feedback of
our partner instructors:

- The popular Matrix App was made fully AA accessible. It is now
operable using fingers on touch screens, and mouse / keyboard on
traditional displays. Watch a short illustrative video at
https://youtu.be/2DjUTkqK5Fk and try it yourself at
- Instructors can clone the course and tweak it to their own needs.
- Solutions to Review Exercises were added.
- The rest of the course is now AA accessible as well.

For free access to the course contact Pavel Solin at pavel@nclab.com.

Subject: New Book, Location Estimation from the Ground Up

2020 / xvi + 200 pages / Softcover and e-book / ISBN 978-1-611976-28-1
SIAM / List $67.00 / Members $47.90

Print (and free access to a sample chapter and the table of contents):
e-book: https://doi.org/10.1137/1.9781611976298
More previews on Google Books: https://books.google.co.il/books?

The book explains the mathematical formulation of location-estimation
problems, the statistical properties of these mathematical models, and
the algorithms that are used to resolve these models to obtain
location estimates.

The presentation emphasizes least squares and linear algebra
techniques, so NA-Digest readers will find the book to be a highly
readable resource on location estimation and on classical estimation
in general. It covers GNSS (GPS) models and algorithms ranging from
the very basic to RTK, a model with integer ambiguities that produces
centimeter-level accurate estimates. It also covers other important
modelling, analytical, and algorithmic techniques, like the Cramer-Rao
bound, separable least- square problem, and Kalman filtering (covered
in a unique way in the sample chapter). The book is suitable for self
study, as a main textbook for courses on location estimation, or as a
source of motivating problems and interesting algorithms for courses
on linear algebra, numerical linear algebra, optimization, and

Subject: Numerical Approximation and Applications, ONLINE, Nov 2020

We are pleased to announce a new series of on-line seminars entitled
"Online Seminars on Numerical Approximation and Applications OSNA^2".

The online series of seminars promotes the interchange among
researchers working in the domain of numerical approximation and its
applications, limited by the COVID-19 pandemic. Since participation in
traditional conferences is difficult, the primary goal of these
webinars is to share novel and attractive ideas via web suggested by
experienced and early-career researchers. As the second aim, the
colloquia intend to bridge the gap between theoretical aspects of
approximation theory and its applications.

OSNA^2 will start on November 9, 2020, at 17:00 (GMT+2) with two talks
per day and a week along four weeks. For more information including
the schedule of the talks please visit the website:
https://sites.google.com/unifi.it/osna2/home-page and contact us for
any questions at osna2.2020@gmail.com

Registration is needed to receive e-mails and virtual connection
access to follow the seminars.

Research assistant at the interface of mathematical optimization and
energy economics (Friedrich-Alexander-Universitat Erlangen-Nurnberg
and/or Trier University)

In the DFG Collaborative Research Center (CRC) 154 "Mathematical
Modelling, Simulation and Optimization using the Example of Gas
Networks", the position of a research assistant is to be filled
starting from March 2021 on. Remuneration is based on salary group E
13 TV-L (75%) and the position is filled for an initial period of 16
months. An extension is possible.

The PhD student will do research at the interface of mathematical
optimization, equilibrium modeling, and theoretical economics with
applications to energy markets and to gas markets, in particular. A
rigorous mathematical modeling of today's liberalized energy markets
leads to multilevel mixed-integer nonlinear optimization problems that
are extremely challenging both from a theoretical as well as from a
computational point of view. In this context, the work's focus will be
on mathematical modeling of multilevel equilibrium problems for energy
markets, on the theoretical analysis of these models, on the
development of tailored solution methods for their resolution, and on
the economic analysis and interpretation of the results to obtain
insights on real-world markets.
