Subject: New Book, Design of Delay-Based Controllers for Linear Time-Invariant Systems
Design of Delay-Based Controllers for Linear Time-Invariant Systems by Adrián
Ramírez, Rifat Sipahi, Sabine Mondié, and Rubén Garrido
This book provides the mathematical foundations needed for designing practical
controllers for linear time-invariant systems. The authors accomplish this by
incorporating intentional time delays into measurements with the goal of
achieving anticipation capabilities, reduction in noise sensitivity, and a fast
response. The benefits of these types of delay-based controllers have long been
recognized, but designing them based on an analytical approach became
possible only recently.
Design of Delay-Based Controllers for Linear Time-Invariant Systems provides a thorough survey of the field and the details of the analytical approaches needed to design delay-based controllers. In addition, readers will find accessible mathematical tools and self-contained proofs for rigorous analysis, numerous examples and comprehensive computational algorithms to motivate the results, and experiments on single-input single-output systems and multi-agent systems using real-world control applications to illustrate the benefits of intentionally inducing delays in control loops.

Subject: New Book, Mathematics and Finite Element Discretizations of Incompressible Navier–Stokes Flows
Mathematics and Finite Element Discretizations of Incompressible Navier–
Stokes Flows: Revised and Expanded Edition by C. Bernardi, V. Girault, F. Hecht,
P.-A. Raviart, and B. Rivière
Navier–Stokes equations are one of the most impactful techniques for
modeling physical flow phenomena. The coupling of velocity and pressure,
along with the nonlinearity, is a challenge for the mathematical and numerical
analysis of these equations. This self-contained book provides a thorough
theoretical study of finite element methods for solving incompressible Navier–
Stokes equations, which model flow of incompressible Newtonian fluids and
are used in many practical applications. It focuses on efficient and widely used
finite element methods that are well adapted to large-scale simulations.
In this revised and expanded edition of Girault and Raviart’s 1986 textbook
Finite Element Methods for Navier–Stokes Equations (Springer-Verlag), readers
will find rigorous proof of stability and convergence, analysis of practical
algorithms, and a stand-alone chapter on finite element methods that is
applicable to a large range of PDEs.
In addition to the basic theoretical analysis, this book covers up-to-date finite
element discretizations of incompressible Navier–Stokes equations; a variety of
numerical algorithms used in the computer implementation of Navier–Stokes
equations and numerical experiments; standard and nonstandard boundary
conditions and their numerical discretizations via the finite element methods;
and conforming and nonconforming finite elements, as well as their stability
and instability.

Subject: Applied and Industrial Mathematics, Germany, Oct 2025
The third edition of the Kaiserslautern Applied and Industrial Mathematics Days –
KLAIM will take place in Kaiserslautern, Germany, from October 6th-8th, 2025.
The purpose of this workshop is to provide a forum for applied mathematicians
from academia, research labs and industry to exchange ideas and to showcase
recent results.
Next year's edition of KLAIM will put emphasis on Coupled Problems.
This focus topic reflects the ever increasing complexity in today's simulation
and optimization methods where different problem stages, different scales, or
different physical domains and effects are connected in various ways.
The workshop is hosted jointly by the Fraunhofer-Institute for Industrial
Mathematics and the Dept. of Mathematics at the RPTU Kaiserslautern-Landau.
The program will be structured along the tracks
1. Coupling across scales - multiscale methods in the materials sciences
2. Coupling across domains - multiphysics simulation
3. Co-simulation and control in coupled engineering applications
4. Coupled discrete and bilevel optimization problems
5. Solver coupling and high performance computing
Additionally, we plan a special session on Success stories from collaboration
projects with industry organized by the European Network EU-MATHS-IN.
Registration and further details will be announced in April 2025.

Subject: PhD Position in Numerical Analysis (Fluid-Structure Interactions), Univ of Konstanz, Germany
A PhD position is available at the University of Konstanz, Germany, within the project “Unfitted finite elements and efficient solvers for fully Eulerian fluid-structure interaction with application to rotating wind turbines” funded by the German Research Foundation (DFG) and led by Stefan Frei (University of Konstanz) and Thomas Wick (University of Hannover). The main objective is to develop, analyse and implement a geometrically unfitted discretisation for fully Eulerian fluid-structure interactions with large solid deflections, based on a cut finite element approach. A special emphasis is on time discretisation for problems involving time-dependent sub-domains, and on turbulence modelling based on the variational multiscale method. A strong background in the numerical analysis of finite element methods and good programming skills, preferably in C++, are expected.
The position at payment-scale TV-L E13 (75%) of the German public service
salary scale is available initially for three years with a starting date between February and May 2025, or as soon as possible thereafter. The University of Konstanz is one of eleven Universities of Excellence in Germany. If you are interested, please send your application (including a CV and a short motivation letter describing your previous research and your motivation for this position, in English or German) via our online application portal before December 31, 2024.

Claremont Graduate University is seeking a postdoctoral fellow (research
assistant professor) to work under the supervision of Professor H.N. Mhaskar
on his project funded by the Office of Naval Research. The candidate should
have a Ph.D. in mathematics or related disciplines. The term is from August 1,
2025 to July 31, 2026. There is some flexibility with the timing. Subsidized
housing may be available https://my.cgu.edu/housing/.
The project consists of developing a new paradigm for machine learning based
on computational harmonic analysis. The appointee will be expected to find
application areas and demonstrate the success of the theory to these areas,
and thus expected to have strong programming background in addition to a
good background in mathematical analysis. The project interacts with several
areas of mathematics: computational harmonic analysis, approximation theory,
orthogonal polynomials, image processing, inverse problems, partial differential
equations, etc. It is not expected that the candidate should be an expert in all
these areas, but should have the enthusiasm and ability to absorb new areas of
knowledge quickly.
To apply, please submit a cover letter, CV (with list of publications), statement
of research interests, and at least three letters of recommendation via
