jif3d is a framework for joint inversion of different types of geophysical data in 3D. It currently comprises forward solvers for first arrival traveltimes, scalar and tensor gravity data, magnetics, magnetotellurics, electrical resistivity tomography and surface waves.The framework is flexible in terms of the coupling approach between the different datasets. At the moment cross-gradient coupling, variation of information and deterministic parameter relationships are implemented. ...

Geophysical Library is a C++-library to handle geophysical data. At the moment the focus is on magnetotelluric and seismic data. It also includes a genetic algorithm for data inversion, signal processing and statistics routines.

The Rotations Conversion Library (RCL) is a collection of C++ functions that address common computations and numerical handling of rotations in 3D Euclidean space, including support for rotation matrices (`Rotmat`), Quaternions (`Quat`), intrinsic ZYX Euler angles (`Euler`), fused angles (`Fused`) and tilt angles (`Tilt`). In addition to the core competency of being able to convert between each of the representations, operations such as inversion, ZYX yaw extraction, fused yaw extraction, renormalisation, equality detection, vector rotation and much more have been implemented. Unit tests for each function are provided to ensure that the library performs exactly as it should. The implementation of the Rotations Conversion Library is based on the very related Matlab/Octave Rotations Library (MORL), which is a highly tested reference implementation for the required algorithms (see https://sourceforge.net/projects/rotationslib/).

A 3D only CAD/CAM program for generating CNC code from existing models. The focus is on importing an existing 3D model (STL files) and providing basic manipulation capability, like rotation, scaling, etc. It does not support building 3D models from scratch. GCode and Shoptbot toolpaths are generated from the model. Multithreaded. This is a standalone companion product to the Techne (R) CAD/CAM project.

Liquid chromatography coupled to mass spectrometry (LC-MS) is the dominant technological platform for proteomics. An LC-MS analysis of a complex biological sample can be visualized as a “map” of which the positional coordinates are the mass-to-charge ratio (m/z) and chromatographic retention time (RT) of the chemical species profiled. Label-free quantitative-proteomics requires the alignment and comparison of multiple LC-MS maps to ascertain the reproducibility of experiments or reveal...

CVM C++ Class Library encapsulates concepts of vector and square, band, symmetric and hermitian matrices in Euclidean space of real and complex numbers. It utilizes BLAS and LAPACK Fortran libraries. See http://cvmlib.com for binaries and more details.
