TeraPy is a modular graphical user interface for terahertz time-domain spectroscopy and other sequential measurements processes.

## Updated 11 Jan 2014 Global Paths Matching

 Pop 44.7 1

Global Paths Matching is an implementation of the global paths graph matching algorithm proposed by Maue and Sanders in "Engineering Algorithms for Approximate Weighted Matching" (WEA'07). Given a graph G=(V,E), a matching M is a set of edges without common vertices, i.e. the graph G=(V,M) has a degree of at most one. The algorithm scans the edges in order of decreasing weight (or rating), constructing a collection of paths and even length cycles. These paths initially contain no edges. While scanning the edges, the set is extended by successively adding applicable edges, which are those connecting two endpoints of different paths or two endpoints of an odd length path. Optimal solutions/matchings are computed for each path and cycle using dynamic programming.

## Updated 03 Mar 2014 KaHIP

 Pop 330.11 3.27

KaHIP - Karlsruhe High Quality Partitioning - is a family of graph partitioning programs that tackle the balanced graph partitioning problem. It focuses on solution quality and implements flow-based methods, more-localized local searches, and several parallel and sequential meta-heuristics.

Some categories included are: acceleration, area, frequency, atomic physics, density, electrical capacitance, electromagnetic radiation, energy/work, flow, force, fuel consumption, illumination, length, luminance, luminous flux, magnetomotive force, mass, power, prefixes and suffixes, pressure and stress, specific heat, speed/velocity, temperature, thermal resistance, time, torque, viscosity (dynamic), viscosity (kinematic), volume, and dry/liquid capacity.

## Updated 18 Jul 2012 GRALE

 Pop 30.05 1

GRALE is a set of tools - a library and a number of accompanying applications - to study gravitational lenses. Gravitational lenses are astronomical objects so massive that their gravitational pull even deflects light rays. This can cause multiple copies of the same background object to be visible, like a cosmic mirage. The locations and shapes of these copies can provide information about the mass distribution of the gravitational lens, which GRALE can help recover using a genetic algorithm-based method. Apart from these so-called lens inversions, it's also possible to simulate gravitational lenses.

## Updated 05 Feb 2012 GraphInsight

 Pop 23.58 28.29

GraphInsight is visualization software that lets you explore graph data through high quality interactive representations. Data exploration and knowledge extraction from graphs is of great interest nowadays: knowledge is disseminated in social networks, and services are powered by cloud computing platforms. Data miners deal with graphs every day. Humans are extremely good at identifying patterns and outliers. Interacting visually with your data can give you better intuition and higher confidence in what you are looking for.

## Updated 29 Sep 2012 SourceAFIS

 Pop 109.33 2.26

SourceAFIS is a fingerprint recognition/matching SDK (library), or more generally an Automated Fingerprint Identification System (AFIS). It essentially compares two fingerprints and decides whether they belong to the same person. It can quickly search a large database of registered fingerprints. It comes with an easy-to-use API (pure .NET and Java) plus assorted applications and tools.

## Updated 26 Mar 2012 ECMWF GRIB

 Pop 29.85 1.72

The ECMWF GRIB API is an application program interface accessible from C and FORTRAN programs developed for encoding and decoding WMO FM-92 GRIB edition 1 and edition 2 messages. A useful set of command line tools is also provided to give quick access to GRIB messages.

## Updated 02 Aug 2010 PySAL

 Pop 23.73 36.79

PySAL (Python Spatial Analysis Library) is a cross-platform library of spatial analysis functions written in Python. It is intended to support the development of high level applications for spatial analysis.

## Updated 02 Jan 2013 GriF

 Pop 51.67 4.55

GriF is a collaborative grid framework to support computational chemistry applications. It is meant to be used as a tool to facilitate massive grid calculations and also to improve scientific collaboration. Accordingly, GriF facilitates profiling the users of grid communities in order to systematically evaluate the work carried out in a grid and to foster its sustainability.
