Subject: Software Release, pyMOR 0.5

The pyMOR development team is happy to announce the release of version
0.5 of pyMOR (

pyMOR is a software library for building model order reduction
applications with the Python programming language. Implemented
algorithms include reduced basis methods for parametric linear and
non-linear problems, as well as system-theoretic methods such as
balanced truncation or IRKA. All algorithms in pyMOR are formulated in
terms of abstract interfaces for seamless integration with external
PDE solver packages. Moreover, pure Python implementations of finite
element and finite volume discretizations using the NumPy/SciPy
scientific computing stack are provided for getting started quickly.

Highlights of this release are:

- Support for Python 3.
- System-theoretic reduction methods.
- Bindings for the NGSolve finite element library.
- New linear algebra algorithms.
- Various VectorArray usability improvements.
- Redesign of pyMOR's projection algorithms based on RuleTables.

professionals to submit theoretical or practical contributions that
aim to present ideas, techniques, and results of parallel computing in
all aspects of string matching and related applications
(exact/approximate string matching, single/multiple string matching,
2D string matching, and compressed string processing). Manuscripts
that focus on research of sequential string-matching algorithms are
welcome. Both original research and comprehensive review/survey papers
are also welcome.

Topics of interest include but are not limited to the following areas:
String matching algorithms (exact/approximate, single/mutiple, two-
dimensional, text compression, etc.); Parallel string-matching
algorithms using OpenMP and/or MPI; Parallel string-matching
algorithms targeting GPUs and many-cores accelerators; Parallel
string-matching applications exploiting FPGA; Distributed string
matching algorithms; Performance study and analysis of large-scale
string-matching applications; Libraries for string matching on
parallel platforms; Applications of string matching in natural
language processing, computational linguistics, information retrieval,
text/opinion mining, text plagiarism, sentiment analysis,
bioinformatics, computational biology, intrusion detection, security, etc.

Please visit the Instructions for Authors page before submitting a
manuscript. The Article Processing Charge (APC) for publication in
this open access journal is 1000 CHF (Swiss Francs). Submitted papers
should be well formatted and use good English. Authors may use MDPI's
English editing service prior to publication or during author revisions.
