...The software can identify and define modules by two different modularity metrics widely used in studies with different types of networks such as social, ecological and biochemical networks. In order to find the network partition that maximizes modularity, the software offers five optimization methods to the user: simulated annealing, fast greedy, spectral partitioning, a hybrid of fast greedy and simulated annealing, and a hybrid of spectral partitioning and simulated annealing. The software is implemented in C language and it uses the igraph library for complex network research.

Finds communities in networks with a submodular algorithm based on the optimization of Newman's modularity. The algorithm finds a weakly optimal community partition of the network. Developed by J. R. Busch, M. G. Beiro and J. I. Alvarez-Hamelin,

...Mixed mortality models, such as in Gompertz-Makeham distribution, consider a more general case where mortality is consist of both age-dependent and in-dependent mortality. Mixed models partition mortality into exogenous and endogenous components, so that the intrinsic survivorship can be estimated without the interference from extrinsic noise. DeDAY supports both interval-censored data and exact event-time data. Using MLE (Maximum Likelihood Estimate), DeDAY fits statistic model to the data. DeDAY also calculates the variances and the multi-dimensional confidence limits of model parameters. ...

...This code, written by Vinh Phu Nguyen, implements one and two dimensional Element Free Galerkin (EFG) method which is one of the most common meshfree methods for elasticity. It also implements Partition of Unity based enrichment for weak and strong discontinuities. The method and the implementation are described in the following article Meshless methods: a review and computer implementation aspects VP Nguyen, T Rabczuk, S Bordas, M Duflot, Mathematics and computer s in simulation 79 (3), 763-813.

The extended finite element method (XFEM) classified, one of the partition of unity method (PUM), allows discontinuities to be simulated independently of the mesh. This is possible by adding appropriate functions to the FE approximation basis, for example, the Heaviside function. The discontinuities can evolve in time, without a need for a conforming mesh. A MATLAB implementation of the XFEM written by VP Nguyen, is given here.

Integration routine to be employed in evaluation of high dimensional integrals arising from problems in statistical mechanics, more specifically the partition function of classical Heisenberg spin-chains, and its resulting derivatives.

splitsmb is a standalone application for calculating topological convergence diagnostics on MrBayes tree-output files (unrooted only at this point). It calculates the average- and maximum standard deviations of partition frequencies between runs.
