"Primer3 is a complete rewrite of the original PRIMER program
(Primer 0.5), written by Steve Lincoln, Mark Daly, and Eric
Lander. See DIFFERENCES FROM EARLIER VERSIONS for a discussion
of how Primer3 differs from its predecessors, Primer 0.5 and
Primer v2.
Primer3 picks primers for PCR reactions, considering as criteria:
o oligonucleotide melting temperature, size, GC content,
and primer-dimer possibilities,
o PCR product size,
o positional constraints within the source sequence, and
o miscellaneous other constraints.
All of these criteria are user-specifiable as constraints, and
some are specifiable as terms in an objective function that
characterizes an optimal primer pair."

The Biopython Project is an international association of developers who are
providing freely available Python tools for use in areas of computational
molecular biology such as bioinformatics and genomics.
Biopython is a collection of Python packages and modules created by the
Biopython Project, intended to provide the basis for building bioinformatics
applications in the Python language.
Note that the current release is alpha quality, and not yet deemed to be
stable.
This port includes optional support for Biopython-CORBA, a CORBA interface
built to the BioCorba standard (http://biocorba.org/).
NASTRAN-95
NASTRAN is the NASA Structural Analysis System, a finite element analysis
(FEA) program completed in the early 1970's. It was the first of its kind
and opened the door to computer-aided engineering. Subsections of a design
can be modeled and then larger groupings of these elements can again be
modeled. NASTRAN can handle elastic stability analysis, complex
eigenvalues for vibration and dynamic stability analysis, dynamic response
for transient and steady state loads, and random excitation, and static
response to concentrated and distributed loads, thermal expansion, and
enforced deformations.
NOTE: There is no technical support available for this software.
The GPL Electronic Design Automation (gEDA) project has produced and
continues working on a full GPL'd suite and toolkit of Electronic
Design Automation tools. These tools are used for electrical circuit
design, schematic capture, simulation, prototyping, and production.
Currently, the gEDA project offers a mature suite of free software
applications for electronics design, including schematic capture,
attribute management, bill of materials (BOM) generation, netlisting
into over 20 netlist formats, analog and digital simulation, and
printed circuit board (PCB) layout.
The gEDA/gaf suite provides schematic capture, netlisting, bill of
materials generation, and many other features.
SPICE is a general-purpose circuit simulation program for nonlinear DC,
nonlinear transient, and linear AC analyses. Circuits may contain resistors,
capacitors, inductors, mutual inductors, independent voltage and current
sources, four types of dependent sources, lossless and lossy transmission
lines (two separate implementations), switches, uniform distributed RC
lines, and the five most common semiconductor devices: diodes, BJTs, JFETs,
MESFETs, and MOSFETs.
Patch Levels I and II (including a new spec command for spectral analysis)
and the level 2 JFET model are courtesy from the Macquarie University.

TOCHNOG is a free finite element program with many features. TOCHNOG
accepts free format input. Boundary conditions can be imposed at
geometrical entities, as well as nodes and elements.
Among the FE models supported are: differential equations (materials),
convection-diffusion equations, Stokes and Navier-Stokes (fluids),
elasticity (isotropy and transverse isotropy), plasticity (Von-Mises,
Mohr-Coulomb, etc.; plastic surfaces can be arbitrarily
combined). Residues in equations and error estimates for all data can
be printed or plotted using gnuplot/plotmtv, CalculiX or gmsh.
TOCHNOG supports a choice of description frames including Lagrangian,
Eulerian and arbitrary Eulerian-Lagrangian (AEL).
VARKON can be used as a traditional CAD-system with drafting, modelling
and visualization if you want to but the real power of VARKON is in
parametric modelling and CAD applications development. VARKON includes
interactive parametric modelling in 2D or 3D but also the unique MBS
programming language integrated in the graphical environment.
The system was originally developed by a group at the University of
Linkoping in Sweden during 1984-86 under the leadership of Dr. Johan
Kjellander who was then the president of Microform AB. From 1986 the
system was owned, marketed and further developed by Microform AB.
What Is QCad?
QCad is a professional CAD System. With QCad you can easily construct
and change drawings with ISO-texts and many other features and save
them as DXF-files. These DXF-files are the interface to many
CAD-systems such as AutoCAD (c) and many others.
What is QCad not?
QCad is no designer tool. That means you can not create any filled
shapes nor any crazy freehand forms. Also you can not drag and drop
the objects in the drawing with the mouse.
If you find any bugs, send a report to bugs@qcad.org.
Xwota is a very simple Linux/FreeBSD/xBSD client for the WOTA Database
(Who is On The Air Database) written by me (IZ0ETE).
It's very similar to a DX Cluster client, but it works with the WOTA server.
If you don't known what is the WOTA DB, please read some info at
http://www.wotadb.org.
It's written in C and GTK, and it should work on the latest
Linux/BSD distributions.
Please report to me your successful installation. (Linux, FreeBSD at the moment)
ish is a format to encode binary files to text file, or decode text
files into binary file. ish has strong error correction/detection
functionality using CRC and checksum.
This format is popular in Japanese BBS'es.
To non-Japanese people:
To produce non-Japanese text a user should use "-s7" option.
Other options such as "-ss" may produce Japanese text.
To Japanese people:
To use ish over NetNews newsgroups (such as fj.*), use "-s7" option.
Use of "-ss" will not give you the optimal performance.
"-ss" option is just for BBSes that use Shift-JIS as their native
Japanese encoding.
