VLE is a multi-modeling and simulation environment to study complex dynamic systems. VLE is based on the discrete event specification DEVS. and it implements the DSDE formalism (A merge of Dynamic Structure DEVS, DSDEVS, with Parallel DEVS, PDEVS). VLE provides a complete set of C++ libraries, called VFL (VLE Foundation Libraries), to develop DEVS models, to gets results of simulations, to launch simulation on cluster. The models can be developed with the DEVS formalism or with the classical mathematical formalism: Ordinary Differential Equation with Euler, Range-Kutta or QSS integrator, Finite state automaton (FDDEVS, UML State chart, Hybrid Petri net).

The m-file overlap_integral.m calculates the vibrational overlap integral between two nuclear wavefunctions using the formalism developed by Sharp and Rosenstock (J. Chem. Phys., 41:3453, 1964). This function requires the MATLAB Symbolic Toolbox in order to run correctly. The m-file make_overlap_table.m demonstrates how to use overlap_integral.m by generating Table V taken from (R. L. Thom, B. M. Wong, R. W. Field, and J. F. Stanton. J. Chem. Phys., 126: 184307, 2007). The m-files b_matrix_acetylene.m and load_acetylene_data.m are specific to acetylene and are required by make_overlap_table.m to run correctly.

VLE or Virtual Environment Laboratory, is a handy, easy to use multimodeling, simulation platform developed on the discrete event formalism DEVS (Discrete Event System Specification).

VLE provides a set of C++ libraries, the VFL (VLE Foundation Libraries) and a lot of programs like a simulator, a graphical user interface to model and develop models and tools to analyze and visualize simulation outputs. The VFL are sufficiently well designed to allow the development of new simulators, models or new programs for modeling and analysis.

libquantum is a C library for the simulation of a quantum computer. Based on the principles of quantum mechanics, it provides an implementation of a quantum register. Basic operations for register manipulation such as the Hadamard gate or the Controlled-NOT gate are available through an easy-to-use interface. Measurements can be performed on either single qubits or the whole quantum register. Features: - Simulation of arbitrary quantum algorithms is possible - High perfomance and low memory consumption - Decoherence support for realistic quantum computation - Interface for quantum error correction (QEC) - Supports the density operator formalism - Implementations of Shor's factoring algorithm and Grover's search algorithm are included.

MetMAP is a MATLAB Toolbox for Metabolical Modeling, Analysis and oPtimization (Met. M. A. P.). You can use this package to study metabolical systems from a theoretical point of view, analysing the pathway's structure and dynamics, but you can also use it for biotechnological purposes, evaluating optimal solutions in a genetical improvement process. All this calculations are evaluated using the S-System formalism (a part of Biochemical Systems Theory, BST) and the Indirect Optimization Method (IOM, developed by Torres, Voit et al).

Reaction Equilibrium designed as a small and simple simulation tool that manages to illustrate qualitative concepts relating to chemical reaction equilibrium.

Problems in reaction equilibria are a staple of physical chemistry and thermodynamics courses, and their treatment via the formalism of the equilibrium constant is familiar to anyone with training in chemistry or chemical engineering.

While the use of these tools is not difficult to learn, an intuitive understanding of the standard Gibbs energy, enthalpy, and entropy of reaction can be more elusive.

Like everything in thermodynamics, they have their origin in molecular-level behaviors, and thus some understanding of them can be gained by observing molecules "react" while following Newtonian mechanics, and seeing how the emergent behavior can be...

PC-KIMMO is a new implementation for microcomputers of a program dubbed KIMMO after its inventor Kimmo Koskenniemi (see Koskenniemi 1983). It is of interest to computational linguists, descriptive linguists, and those developing natural language processing systems. The program is designed to generate (produce) and/or recognize (parse) words using a two-level model of word structure in which a word is represented as a correspondence between its lexical level form and its surface level form..
