Subject: New Book, Mathematical Foundations of Finite Elements and Iterative Solvers


Mathematical Foundations of Finite Elements and Iterative Solvers
by Paolo Gatto

This textbook describes the mathematical principles of the finite
element method, a technique that turns a (linear) partial differential
equation into a discrete linear system, often amenable to fast linear
algebra. Reflecting the author's decade of experience in the field,
Mathematical Foundations of Finite Elements and Iterative Solvers:

- examines the crucial interplay between analysis, discretization, and
computations in modern numerical analysis,
- recounts historical developments leading to current state-of-the-art
techniques, and
- while self-contained, provides a clear and in-depth discussion of
several topics, including elliptic problems, continuous Galerkin
methods, iterative solvers, advection-diffusion problems, and saddle
point problems.

Accessible to readers with a beginning background in functional
analysis and linear algebra, this text can be used in graduate-level
courses on advanced numerical analysis, data science, numerical
optimization, and approximation theory.

Subject: Postdoc Position, FEM & Topology Optimization, Univ of Campinas


A call for applications for a postdoctoral position is open at the
Institute of Mathematics, Statistics and Scientific Computing of the
University of Campinas, on the topics of the project "Application of
Mixed-Hybrid Finite Element Methods to Topology Optimization including
Additive Manufacturing".

This project involves the study, development, and application of
finite element methods to problems related to topological optimization
of mechanical structures, including the additive manufacturing
process. In such problems, it is common to the multiphysics modeling,
where thermal and mechanical responses are considered, normally
written in terms of elliptic and parabolic partial differential
equations. The objective of this research is the development and use
of mixed and mixed-hybrid finite element formulations for the accurate
approximation of state variables, such as displacement and stress in
the elasticity problem and temperature and heat flow in the thermal
problem, to be used in the topological optimization.

It is recommended that the candidate has expertise in finite elements,
mathematical modeling, optimization, and scientific computing,
particularly using FEniCS.

The candidate will be based in Campinas, Brazil. The position is
initially for one year and can be renewed depending on
performance. The starting date (flexible) is from September 2022.

To apply, please send a CV and at least one reference letter to
maicon@ime.unicamp.br, in an email with the subject "PostDoc
Application". Applications are open until July 29, 2022.

Subject: Postdoc Position, Image Analysis/Computer Vision, Tufts


I have an immediate opening for a post-doctoral research associate to
undertake a project focusing on the development of processing and
analysis methods to address problems of denoising, segmentation, and
adaptive sampling/acquisition of 4D (3 space + time) two-photon
excited fluorescence (TPEF) data cubes. This work will be performed
in collaboration with a team of biomedical engineers seeking to
understand the role of metabolic dysfunction at the onset of
Alzheimer's disease (AD) using information that can be gleaned from
dynamic, TPEF data collected from human brain-like AD tissue models.
More specifically, a key aim of the project is to develop the models
and processing tools to extract from these data robust optical
metabolic readouts of AD tissue models monitored dynamically to
identify the changes that occur at the onset of neuroinflammation and
plaque-like formation and the extent to which they are reversed upon
interventions.

Applicants must have a PhD in electrical engineering, computer
science, applied mathematics, statistics or a similar field. The
ideal candidates will have experience with modern methods of image
processing, mathematical imaging, and/or computer vision and a strong
technical background in one or more of the following: machine
learning, statistical signal and image processing, optimization, and
data science. Programming experience in Matlab or python is
