This is a simulation package developed for numerical simulation of ultrashort pulse propagation in optical media and pulse generation from mode-locked lasers. Although the code is primarily intended for investigations of fiber links, fiber amplifiers and fiber lasers, it can be applied to any other setting for which the governing equiations are valid. The physics included in the code is based on a generalized nonlinear Schrödinger equation, including higher order dispersion, stimulated Raman...

WavePacket is a program package for numerical simulation of quantum-mechanical wavepacket dynamics of distinguishable particles. It can be used to solve single or coupled time-independent or time-dependent (linear) Schrödinger and Liouville-von Neumann-equations, partly also classical or quantum-classical Liouville equations. Optionally accounting for the interaction with external electric fields within the semiclassical dipole approximation, WavePacket can be used to simulate modern...

This is a standalone program for a) the calculation of diffusion coefficients of sorbates inside nanoporous materials at different loadings by using transition rate constants and for b) solving the master equation for a system consisted of a large number of unit cells per each direction. It is based on the following published paper "Kolokathis, P. D., Braun, O. M.. J. Comput. Chem. 2019, 40, 2053– 2066. DOI: 10.1002/jcc.25857"

WavePacket is a program package for numerical quantum-mechanics of distinguishable particles. It can be used to solve single or coupled time-independent or time-dependent (linear) Schrödinger and Liouville-von Neumann-equations, as well as classical or quantum-classical Liouville equations. Optionally accounting for the interaction with external electric fields within the semiclassical dipole approximation, WavePacket can be used to simulate modern experiments involving ultrashort light...

A MATLAB toolbox for approximate Bayesian computation (ABC) in stochastic differential equation models. 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...

Science based weld software to develop optimal automatic weld procedures. SmartWeld is a PC based tool for designers, engineers, and technicians to aid in selecting, optimizing, and configuring automated welding processes.

<Temporarily Unavailable Online> This project is aiming at completing a library of open codes (mainly based on MATLAB at present) to deal with Dipoles-Cavity Interaction problems. Common methods, including Green's function method and Master Equation method et al, will be applied to the coding. Samples of calculations and standard comparison with publications using the library will be given for demonstration of the usage. Interface to some commonly used software, such as Lumerical FDTD Solutions...

An easy to install and use toolbox for octave for the calculation purpose of power system along with features like Economic load dispatch, load flow analysis, transmission line parameter and swing equation etc

Implementation of the spherical base solutions of the Helmholtz equation in spherical coordinates, and translations / rotations of the coordinate system thereof in MATLAB and C.

A MATLAB package to simulate sample paths of the solution of a Itô or Stratonovich stochastic differential equation (SDE), compute statistics and estimate the parameters from data. A note of caution: SDE Toolbox is no more developed but it's still downloadable. Its inferential capabilities can be considered surpassed (at best). Actually the parameter estimation methods were already far from the state-of-art when the project began in 2007 (!). The considered implemented parametric and non...
