The G.722 module is a bit exact implementation of the ITU G.722 specification
for all three specified bit rates - 64000bps, 56000bps and 48000bps. It passes
the ITU tests.
To allow fast and flexible interworking with narrow band telephony, the encoder
and decoder support an option for the linear audio to be an 8k samples/second
stream. In this mode the codec is considerably faster, and still fully
compatible with wideband terminals using G.722.
TiMidity++ is a MIDI player without external MIDI instruments.
This can also convert MIDI files to various formatted audio files
(ex. wav, au, etc..).
In addition to this port, "Gravis Ultra Sound" compatible patch files
(or SF2 format SoundFont) are required to play files.
Formerly, the original version of this program was written by Tuuka
Toivonen(until version 0.2i).
Now, Masanao Izumo and many hackers are developing "TiMidity++".
TTCP is a benchmarking tool for determining TCP and UDP performance
between 2 systems.
The program was created at the US Army Ballistics Research Lab (BRL)
and is in the public domain. Feel free to distribute this program
but please do leave the credit notices in the source and man page intact.
How to get TCP performance numbers:
receiver sender
host1% ttcp -r -s host2% ttcp -t -s host1
-n and -l options change the number and size of the buffers.
The BioJava Project is an open-source project dedicated to providing Java
tools for processing biological data. This will include objects for
manipulating sequences, file parsers, CORBA interoperability, access to
ACeDB, dynamic programming, and simple statistical routines.
The BioJava library is useful for automating those daily and mundane
bioinformatics tasks. As the library matures, the BioJava libraries will
provide a foundation upon which both free software and commercial packages
can be developed.
Free, open source molecular viewer and editor for
protein structure, DNA structure, PDB, molecular rendering,
biological macromolecule.
Atoms may be drawn as spheres of different sizes.
Bonds may be drawn as cylindrical sticks, conical sticks or
as curved surfaces.
Five types of slab are available: planar, spherical,
semi-spherical, cylindrical and semi-cylindrical.
The slab position and thickness are visible in a small window.
Atomic bonds as well as atoms are treated as independent drawable objects.
and more.
Fluctuate fits the model which has a single population which has been growing
(or shrinking) according to an exponential growth law. It estimates 4Nu and
g, where N is the effective population size, u is the neutral mutation rate
per site, and g is the growth rate of the population.
Fluctuate forms part of the Lamarc (Likelihood Analysis with Metropolis
Algorithm using Random Coalescence) suite. See:

tRNAscan-SE was written in the PERL (version 5.0) script language.
Input consists of DNA or RNA sequences in FASTA format. tRNA
predictions are output in standard tabular or ACeDB format.
tRNAscan-SE does no tRNA detection itself, but instead combines the
strengths of three independent tRNA prediction programs by negotiating
the flow of information between them, performing a limited amount of
post-processing, and outputting the results in one of several
formats.
Dinotrace is a signal waveform tracing tool that supports traces in the form of
Verilog Value Change Dump (VCD), ASCII, Verilator, Tempest CCLI, COSMOS, Chango
and Decsim Binary. Dinotrace is also equipped with an interface to GNU Emacs.
Dinotrace was conceived in the early 1980's by Allen Gallotta at Digital
Equipment Corporation, who wrote the code and supported it through version 4.2.
When created, it was the first graphical display tool for the simulators being
designed at Digital.
Electric is a sophisticated electrical CAD system that can handle
many forms of circuit design, including:
Custom IC layout (ASICs)
Schematic drawing
Hardware description language specifications
Electro-mechanical hybrid layout
(snip, this is an edited version of Electric's homepage)
Electric handles these file formats:
CIF I/O
GDS I/O
VHDL I/O
DXF I/O
PostScript, HPGL, and QuickDraw output
For real functionality, one should consider installing
support simulation software such as cad/spice.
FEAPpv is a general purpose finite element analysis program which is
designed for research and educational use. The program is described in the
references:
The Finite Element Method, 6th ed., Vols. 1 and 2, by O.C. Zienkiewicz and
R.L. Taylor, Elsevier, Oxford, 2005.
FEAPpv is designed to be compatible for compilation in Unix/Linux and
Windows PC environments.
No support on use of the program will be provided.
