DAE Tools is cross-platform equation-oriented process modelling, simulation, and optimization software. Various types of processes (lumped or distributed, steady-state or dynamic) can be modelled and optimized. They may range from very simple to those which require complex operating procedures. Equations can be ordinary or discontinuous, where discontinuities are automatically handled by the framework. Model reports containing all information about a model can be exported in XML MathML format, automatically creating high-quality documentation. The simulation results can be visualized, plotted, and/or exported into various formats.
HyperList.vim is a Vim plugin for handling HyperLists. HyperList is a methodology to describe anything: any state, item(s), pattern, action, process, transition, program, instruction set, etc. HyperList can be used as an outliner, a TODO-list solution, a project management tool, a business process management aid, a data modeler, a use case facilitator, or for any other application that makes use of descriptions of states or transitions. This plugin does both highlighting and various automatic handling of HyperList, like collapsing lists or parts of lists in a sophisticated way. Since HyperList.vim can also encrypt your lists, it can be used as a very structured password safe.
Sea Ice is software for modeling the microwave emissivity of sea ice. It includes two plane-parallel radiative transfer models: a Monte Carlo ray tracing simulation that models ridged ice, and thermodynamic models that can be used to generate input to the emissivity models in the form of temperature and salinity profiles. It is written in C++ and Interactive Data Language (IDL). It has been used to generate results for several papers on sea ice emissivity.
