- The main goal is to create numerical programs directly from Feynman rules. It is actually developed for few known models like the electroweak standard model and QED, and the limit of application is, for the moment, the 2 to 2 particles reactions involving only external fermions
- AeroCalc is a python package that performs various aeronautical engineering calculations. Currently, it contains the following main modules:
- Alpine3D is a spatially distributed (surface), three dimensional (atmospheric) model for analyzing and predicting dynamics of snow-dominated surface processes in mountainous topography. It includes models for snow cover (SNOWPACK), vegetation and soil, snow transport, radiation transfer and runoff which can be enabled or disabled on demand.
- 'atlc' (Arbitrary Transmission Line Calculator) is a computer aided design (CAD) package for designing and analysing electrical transmission lines and directional couplers of totally arbitrary cross section, with an arbitrary number of different dielectrics. The analysis programs in 'atlc' lets users find the electrical properties of a transmission line or coupler whose physical dimensions are known. The design programs lets users physically realise a transmission line or coupler with certain given electrical properties. The package supports multiple CPUs, as some parts are CPU intensive. It is most likely to be useful to radio amateurs.
- BOTEC is a simple astrophysical and orbital mechanics calculator, including a database of all named Solar System objects. BOTEC is intended as a simple but useful calculator to assist with making astrophysical, orbital mechanics, and space navigation calculations. As the origin of the acronym applies, BOTEC is more of a "back-of-the-envelope calculator" rather than an industrial-strength calculator, although this may change in the future.
- 'CLHelp' is a set of HEP (High Energy Physics)-specific foundation and utility classes such as random generators, physics vectors, geometry, and linear algebra.
- cl-ana is a library of modular utilities for reasonably high performance data analysis & visualization using Common Lisp. (Reasonably means I have to be able to use it for analyzing particle accelerator data). The library is made of various sublibraries and is designed in a very bottom-up way so that if you don't care about some feature you don't have to load it.
The functionality support so far are
- Tabular data analysis: Read-write of large datasets stored in HDF5 files are supported, along with ntuple datasets, CSVs, and in-memory data tables. Users can add their own table types by defining 4 methods and extending the table CLOS type.
- Histograms: Binned data analysis is supported with both contiguous and sparse histogram types; functional interface is provided via map (which allows reduce/fold) and filter.
- Plotting: Uses gnuplot for plotting dataset samples, plain-old lisp functions, histograms, strings-as-formulae, and anything else the user wishes to add via methods on a couple of generics.
- Fitting: Uses GSL for non-linear least squares fitting. Uses plain-old lisp functions as the fit functions and can fit against dataset samples, histograms, and whatever the user adds.
- Generic mathematics: CL doesn't provide extendable math functions, so cl-ana provides these as well as a convenient mechanism (a single function) for using these functions instead of the non-extendable versions. Already included are error propogation and quantities (values with units, e.g. 5 meters) as well as a GNU Octave-style handling of sequences (e.g. (+ (1 2) (3 4)) --> (4 6)).
- The dimnum library contains templated C++ classes for storage and manipulation of dimensionful numbers, as encountered in physics and engineering. Since it uses templates, there is no size or speed penalty with respect to normal variables (depending on compiler optimisations).
- 'EPICS' is a software infrastructure for building distributed control systems to operate devices such as particle accelerators, large experiments and major telescopes. These systems comprise tens or hundreds of computers, networked together so they can communicate and provide control and feedback of the various parts from a control room, or remotely over the Internet. EPICS uses Client/Server and Publish/Subscribe techniques to communicate between the various computers. Most servers (called Input/Output Controllers or IOCs) perform real-world I/O and local control tasks, and publish this information to clients using the Channel Access (CA) network protocol. CA is specially designed for the kind of high bandwidth, soft real-time networking applications that EPICS is used for, and is one reason why it can be used to build a control system comprising hundreds of computers.
