MesoRD is a stochastic and deterministic simulator of coupled chemical reactions and diffusions in space.

Niche Analyst (NicheA) was developed based on the BAM framework which allows users to create virtual spaces and virtual species, and to analyze ecological niches in both multivariate environmental and geographic spaces, linking views of the niche in the two spaces. The unique functionality in NicheA, not available in other software programs, is estimating Grinnellian niches of species based on environmental variables and occurrence records, but with a clear focus on fundamental ecological...

...It performs approximate Bayesian computation for stochastic models having latent dynamics defined by stochastic differential equations (SDEs) and not limited to the "state-space" modelling framework. Both one- and multi-dimensional SDE systems are supported and partially observed systems are easily accommodated. Variance components for the "measurement error" affecting the data/observations can be estimated. A 50-pages Reference Manual is provided with two case-studies implemented and discussed. The methodology is based on the research article available at http://arxiv.org/abs/1204.5459 Author's research page is http://www.maths.lth.se/matstat/staff/umberto/

This project provides the source code for the Mitochondiral Infectious Damage Adaptation (MIDA) model of aging. A probabilistic modeling approach is applied by solving the master equation in mitochondrial quality state space in the presence of fusion-fission events, decay of functional quality, mitophagy and mitochondrial biogenesis, as well as molecular damage originating from a random source or from infectious events during fusion and fission. The provided source code is written in C and performs the time integration of the master equation for the time-evolution of the probability to find mitochondria in states of quality q at time t. ...

This is a c-library that provides tools for advanced analysis of electrophysiological data. It features denoising, unsupervised classification, time-frequency analysis, phase-space analysis, neural networks, time-warping and more.

The Disease Simulation Framework (DiSiF) represents a spatial simulation environment for infectious viral disease spread. The framework currently embodies a very simple framework for simulation in 2D space with focus on SARS and the Common Flu.

Acre calculates growing-space or stand-density of trees and creats pictures of it. It can also be used to calculate weighted Voronoi-Diagrams (splits up an area to the neares point or to the point with the greatest influence at a certain place).

A straight-forward Java implementation of a mixture model with pluggable mixture functions, e.g. a mixture of Gaussian functions. The number and dimensionality of the mixture functions is not limited. All critical calculations are performed in log-space.
