Represent the position of an atom using internal coordinates
Perl module implements an object class for representing internal
coordinates and provides methods for converting them to Cartesian
coordinates.
Perl toolkit to describe macromolecules
Chemistry-MacroMol is a toolkit includes basic objects and methods to
describe macromolecules, a macromolecule is just a molecule that
consists of several "domains". For example, a protein consists
of aminoacid residues, or a nucleic acid consists of bases. Therefore
Chemistry::MacroMol is derived from Chemistry::Mol, with additional
methods to handle the domains.

Perl toolkit to describe molecules
Chemistr-Mol is a toolkit includes basic objects and methods to
describe molecules. It consists of several modules: Chemistry::Mol,
Chemistry::Atom, Chemistry::Bond, and Chemistry::File.
They are the core modules of the PerlMol toolkit, see:
http://www.perlmol.org/.
Generic visualization tool for GNUstep (Gantt chart and more)
Paje is a graphical tool that displays traces produced during the
execution of multithreaded programs. Other programs can also generate
traces for this tool.
Key Features
* Supports multi threaded programs
- each thread of the analysed program can be individually displayed,
or multiple threads can be combined, to reduce screen space usage.
* Interactivity
- each entity represented on the screen can be interrogated for
more information,
- related entities are highlighted as mouse cursor passes over
some representation

Chemical substructure pattern matching
Perl module which implements basic pattern matching for molecules.
Represent a ring as a substructure of a molecule
Explicit chemical reactions
Represent a ring as a substructure of a molecule
Perl module which provides some basic methods for representing a ring.
Multipole-accelerated inductance analysis program
FastHenry computes the frequency dependent self and mutual inductances and
resistances between conductors of complex shape. The algorithm used in
FastHenry is an acceleration of rge mesh formulation approach. The linear system
resulting from the mesh formulation is solved using a generalized minimal
residual algorithm with a fast multipole algorithm to efficiently compute the
iterates.
--------------------- Superconductivity Support -------------------------
This version of fasthenry has been modified to support superconducting
segments and ground planes by Stephen R. Whiteley of Whitleley Research Inc.
The analysis used is based on the London equations and the two-fluid
model. Both reactive and lossy components of the superconductor complex
conductivity are employed in obtaining the impedance matrix.
