BioMAJ (BIOlogie Mises A Jour) is a workflow engine dedicated to data synchronization and processing. It automates the update cycle and the supervision of the locally mirrored data repository. The application is generalist, but was applied in the bioinformatics field for biological data bank management. The packaging includes workflow and indexing post-processing scripts for most used biological data banks. Developed in Java and Ant, the application is compatible with various Unix-based systems.
BitDew is a programmable environment for the management and distribution of data for grid, desktop grid, and cloud systems. It can easily be integrated into large scale computational systems such as XtremWeb, BOINC, Hadoop, Condor, Glite, Unicore, OpenStack, and Eucalyptus. It provides key P2P, grid, and cloud technologies (DHT, BitTorrent, Amazon S3, DropBox) and high level programming interfaces with a simple API for creating, accessing, storing, and moving data with ease, even in highly dynamic and volatile environments.
GREYCstoration is an image regularization algorithm that processes an image by locally removing small variations of pixel intensities while preserving significant global image features, such as sharp edges and corners. The most direct application is denoising. By extension, it can also be used to inpaint or resize images. It is based on methods using nonlinear multi-valued diffusion PDEs (Partial Differential Equations) for image regularization. This kind of method generally outperforms basic image filtering techniques (such as convolution, median filtering, etc.) classically encountered in painting programs. Other image denoising plugins are available, but are not free, and the corresponding algorithms are kept secret.
MapReduce-BitDew is an implementation of the MapReduce programming model proposed by Google for Internet Desktop Grids. Using MapReduce-BitDew, you can execute MapReduce applications on resources like Desktop PCs distributed on the Internet. MapReduce-BitDew features a firewall-friendly protocol, fault-tolerance, result-certification, 2-level schedulers, and more.
MyCGR implements the research of the thesis of Peggy Cénac regarding the use of CGR (Chaos Game Representation) to build a new family of tests for the structure of sequences. It can empirically check the level and power of the tests and apply them on DNA sequences. It can generalize the dinucleotide abundance profile to a CGR-based relative abundance profile and use this profile on DNA sequences to build taxonomy trees and to define CGR-trees.
PTK is an alternative advanced interface for the TSK (The Sleuth Kit) suite. It was developed from scratch. Besides providing the functions already present in Autopsy, it implements numerous new features essential during forensic activity. PTK provides a graphical and highly professional interface based on AJAX technology. It also offers a great deal of features like analysis, search, and management of complex cases of digital investigation.
SHTns is a high-performance Spherical Harmonic Transform library. It was designed for numerical simulation (fluid flows, mhd, etc.) in spherical geometries, but can be used for any kind of problem involving scalar or vector spherical harmonics. It is very fast, thanks to careful vectorization and runtime tuning. It supports multi-threaded transforms via OpenMP. It features scalar and vector transforms, synthesis and analysis, and flexible truncation and normalization. A Python interface is included.
