Ruby binding to CDO (Climate Data Operators)

Java based Smith chart program. Performs single-frequency and sweep charting with both Smitch charts and SWR/PWR curves. Does drag-and-drop schematic entry with direct entry of component values as well as "drag tuning". Can import load parameters directly from the following: - EZNEC (and EZNEC GAM files) - miniVNA and miniVNApro - AIM4170 - CocoaNEC - Rig Expert ".aaplot" files - Touchstone S1P ".s1p" files (shunt and series)

This is a Ruby interface to the scientific graphic library DCL.

SVMlight is an implementation of Vapnik's Support Vector Machine [Vapnik, 1995] for the problem of pattern recognition, for the problem of regression, and for the problem of learning a ranking function. The optimization algorithms used in SVMlight are described in [Joachims, 2002a ]. [Joachims, 1999a]. The algorithm has scalable memory requirements and can handle problems with many thousands of support vectors efficiently. The software also provides methods for assessing the generalization performance efficiently. It includes two efficient estimation methods for both error rate and precision/recall. XiAlpha-estimates [Joachims, 2002a, Joachims, 2000b] can be computed at essentially no computational expense, but they are conservatively biased. Almost unbiased estimates provides leave-one-out testing. SVMlight exploits that the results of most leave-one-outs (often more than 99%) are predetermined and need not be computed [Joachims, 2002a].

This is a Ruby interface to the NetCDF scientific IO library.

The sigrok project aims at creating a portable, cross-platform, Free/Libre/Open-Source signal analysis software suite that supports various device types, such as logic analyzers, MSOs, oscilloscopes, multimeters, LCR meters, sound level meters, thermometers, hygrometers, anemometers, light meters, DAQs, dataloggers, function generators, spectrum analyzers, power supplies, GPIB interfaces, and more. sigrok-cli is a command-line tool written in C, which uses both libsigrok and libsigrokdecode to provide the basic sigrok functionality from the command-line. Among other things, it's useful for scripting purposes.

sigrok-firmware is a collection of firmware files required for some of the devices libsigrok supports (logic analyzers, oscilloscopes, or others). We only carry firmware files for which we have an explicit permission/license that allows at _least_ redistribution of the firmware.

Equake is a panel plugin which monitors and displays earthquakes each time a new one occurs.

Step is an interactive physics simulator. It works like this: you place some bodies on the scene, add some forces such as gravity or springs, then click "Simulate" and Step shows you how your scene will evolve according to the laws of physics. You can change every property of bodies/forces in your experiment (even during simulation) and see how this will change the outcome of the experiment. With Step you can not only learn but feel how physics works!

Szip is an implementation of the extended-Rice lossless compression algorithm.
