Homepage & docs: http://marcoalopez.github.io/GrainSizeTools/ GrainSizeTools is a free, open-source, cross-platform script written in Python that provides several tools for (1) estimating average grain size in polycrystalline materials, (2) characterizing the nature of the distribution of grain sizes (either from apparent distributions or approximating 3D grain size distributions via stereology), and estimating differential stress via paleopizometers. The script requires as the input the...

WODA (Well Outline and Design Aid) is a groundwater simulator developed at the Group for Numerical Analysis, Jaroslav Cerni Institute, Belgrade, Serbia. WODA does not have its own graphical user interface, but it can work with groundwater models constructed using the freely available Lizza interface, http://www.bioirc.ac.rs/index.php/groundwater-flow-software.

Folder is a tool to simulate and analyse the development of structures in mechanically layered media during layer parallel shortening or extension. It includes a graphical user interface that allows for easy designing of complex geometrical models, defining material parameters (including linear and non-linear rheology), and specifying type and amount of deformation. It also includes a range of features that facilitate the visualization and examination of various relevant quantities e.g. velocities, stress, rate of deformation, pressure, and finite strain. Folder contains a separate application, which illustrates analytical solutions of growth rate spectra for buckling and necking of a single viscous layer. ...

Along with calculating basic statistics and quality parameters such as mean and variance, the soft-ware is capable of importing and visualizing different standard time series formats, determining and removing jumps and outliers, and makes numerical and publication quality graphical outputs. Bivariate statistical analysis (including correlation coefficient and linear regression) and time series analysis (including auto and cross-spectral analysis, wavelet power spectrum, spectrogram and periodicities) form the main analysis features of the software.

Starting from GIMMS values as ascii data (each line will be treated as individual time series), the application can smooth the ts - values by applying different algorithm that are based on Fouriertransformation. Separation of seasonal figure as well as the detection of linear trends is possible. Possible breaks in longterm mean can be detected with a change-point analysis using CuSum algorithms. Phenological events such as start-of-season, day-of-max/day-of-min, end-of-season can be determined via threshold-based algorithms or via analysis of max. increase of NDVI during green-up. These analyses work also for multimodal phenologies where individual seasons (partly) interfere each other. ...

Simulates data from a gaussian/beta/piecewise-linear species response function on an environmental gradient, with different sampling (error) distributions. See "Cline (biology)" on wikipedia.org.

A set of R functions (www.r-project.org) for simple hydrological models, based on linear and non-linear storages, MC simulation and multi-objective evaluation. The code provided here is aimed to be transformed into a proper R package at some point.
