gap-core
GAP computer algebra system, core components
GAP is a system for computational discrete algebra, with particular emphasis
on Computational Group Theory. GAP provides a programming language, a library
of thousands of functions implementing algebraic algorithms written in the GAP
language as well as large data libraries of algebraic objects. GAP is used in
research and teaching for studying groups and their representations, rings,
vector spaces, algebras, combinatorial structures, and more.
python-polybori
transitional package
The core of PolyBoRi is a C++ library, which provides high-level data
types for Boolean polynomials and monomials, exponent vectors, as
well as for the underlying polynomial rings and subsets of the
powerset of the Boolean variables. As a unique approach, binary
decision diagrams are used as internal storage type for polynomial
structures. On top of this C++-library a Python interface
is provided. This allows parsing of complex polynomial systems, as well
as sophisticated and extendable strategies for Groebner base
computation. PolyBoRi features a powerful reference implementation
for Groebner basis computation.
seccure
tools for using algorithms based on elliptic curve cryptography (ECC)
The seccure toolset implements a selection of asymmetric algorithms
based on elliptic curve cryptography (ECC). In particular, it offers
public key encryption / decryption and signature generation /
verification. ECC schemes offer a much better key size to security
ratio than classical systems (RSA, DSA). Keys are short enough to make
direct specification of keys on the command line possible (sometimes
this is more convenient than the management of PGP-like key
rings). seccure builds on this feature and therefore is the tool of
choice whenever lightweight asymmetric cryptography -- independent of
key servers, revocation certificates, the Web of Trust, or even
configuration files -- is required.
python-shapely
geometric objects, predicates, and operations (Python 2)
Shapely is a package for manipulation and analysis of 2D features.
Its capabilities include:
* calculating the point set unions, intersections, or differences of features
* predicate tests on features: intersects, touches, contains, and more.
python-openbabel
Chemical toolbox library (python bindings)
Open Babel is a chemical toolbox designed to speak the many languages of
chemical data. It allows one to search, convert, analyze, or store data from
molecular modeling, chemistry, solid-state materials, biochemistry, or related
areas. Features include:
pyfai
Fast Azimuthal Integration scripts
PyFAI is a Python library for azimuthal integration; it allows the conversion
of diffraction images taken with 2D detectors like CCD cameras into X-Ray
powder patterns that can be used by other software like Rietveld refinement
tools (i.e. FullProf), phase analysis or texture analysis.
