DARPA Urban Challenge, a C++ based platform for testing Path Planning Algorithms: An application of Game Theory and Neural Networks. Rubin, Raphael (2007)

A basic simulation of aircraft emergency evacuation developed in CELL-DEVS using the CD++ Toolkit. A python script was then adapted to visualize this project in Blender. Code on SVN only at this time.

A portable, high-level 3D engine with an emphasis on generality. So far it is mainly used in CAD applications in need of geometrical constraint solving and other geometrical methods. FreeSG is designed as an integrable component and not a framework.

GSH builder is a free Galois Sub-Hierarchy visualization tool. The algorithm for calculating GSH is called Pluton and the present Java realization is based on two articles. "Efficiently computing a linear extension of the sub-hierarchy of a Concept Lattice" by Anne Berry, Marianne Huchard, Ross M. McConnell, Alain Sigayret and Jeremy P. Spinrad. "Performances of Galois Sub-hierarchy-building algorithms" by Gabriela Arevalo, Anne Berry, Marianne Huchard, Guillaume Perrot and Alain Sigayret In you're in need of other GSH algorithms or their realizations in C++, you might want to investigate a project called Galicia on sourceforge. This program is free software and is licensed under GNU General Public License as published by the Free Software Foundation. Only jre7 compliant at the moment.

Gaphor is a UML modeling environment written in Python. Gaphor is small and very extensible. The repository is located at http://github.com/gaphor/gaphor.

JointJS is the open source HTML 5 JavaScript diagramming library. JointJS is a comprehensive framework for building fully interactive diagramming tools and application builders. JointJS makes it easy to create visual languages & tools of various kinds. The event-driven nature together with MVC architecture of JointJS makes it easy to plug-in any backend application. Whether you're creating a state machine builder, modeling tool, voice application designer, system monitoring tool, electronic circuits simulator, information system browser and editor, implementing a visual programming language or building a graph visualization with interaction, JointJS is the toolkit that makes your life easier.

Koolon is a simple graph (network) modeling tool with interactive data visualization like Prefuse. It allow to create entities, relations, ontologies, directed and undirected graphs and any abstract network models.

LSystemBuilder is a program for editing and visualizing L-systems. LSystemBuilder makes it easy to explore fractals, FASS-curves and complex branching structures. Naturally LSystemBuilder comes packed with loads of predefined L-systems.

MASyV (Multi-Agent System Visualization) enables one to write agent-based models/cellular automata, eg. in C, visualize them in real time & capture to movie file with MASyVs GUI & message passing lib. Includes examples: Hello World, ants, viral infection

MEM Net - Mote EMulator Network. This project will focus on: 1) MEM - Wireless Sensor Node (mote) emulator 2) MEM Net - network of emulated motes So far, the only released package is “visual-sim-slides”. More comming next !

MSCViewer is a tool intended for debugging of control flows in concurrent, distributed systems. The tool loads logs generated by various entities in the system and visualize a sequence diagram chart for events and interactions. The diagram is fully interactive: entity can be added/removed from the diagram and shuffled; events can be filtered, searched, highlighted and annotated with comments. MSCViewer features integration with a Python interpreter which allows writing Python scripts interacting with the model. This powerful feature can be used to automate validatation of distributed control flows, integrate with graphing infrastructure, etc.

SYSTEM FOR DESIGNING AND SIMULATE CONCURRENT AND DISTRIBUTED PROGRAMS IN CLUSTER ARCHITECTURE Provides graphical interface for configuring relationships between cooperating, abstract processes and simulate it in real cluster environment, using MPI.

Mosby is a model-view-presenter and model-view-intent library designed specifically for Android apps. Migrating a Mosby 2.x based app to Mosby 3.0 should be straightforward. Just replace all import statements of your app in android studio. Mosby has a plugin for Conductor. The aim of this library is to help you build modern android apps with a clean Model-View-Presenter architecture. Furthermore, Mosby helps you to handle screen orientation changes by introducing ViewState and retaining Presenters. At first glance Mosby looks a lot like a framework. There are some classes like MvpFragment you can extends from, but the point is that you don’t have to if you don’t want to. At it’s core Mosby is a tiny library based on delegation. So you don’t have to use MvpFragment if you don’t want to. You can use delegation and composition to integrate Mosby in your own development stack. Hence you are not caught into a frameworks boundaries and limits.

Nmdepend is a lightweight 'link-time' dependency analyzer for C++. It uses object files and libraries instead of source-code as input. It can help to manage 'cross-directory' dependencies. Dependencies can be visualized in combination with Graphviz.

Ocular is a spreadsheet written entirely in python. Cell contents are evaluated by python after any standard spreadsheet coordinates are parsed. This allows the full Monty from Python to be implemented in a visual environment.

OrientDB is an Open Source Multi-Model NoSQL DBMS with the support of Native Graphs, Documents, Full-Text search, Reactivity, Geo-Spatial and Object Oriented concepts. It's written in Java and it's amazingly fast. No expensive run-time JOINs, connections are managed as persistent pointers between records. You can traverse thousands of records in no time. Supports schema-less, schema-full and schema-mixed modes. Has a strong security profiling system based on user, roles and predicate security and supports SQL amongst the query languages. Thanks to the SQL layer it's straightforward to use for people skilled in the Relational world. OrientDB adheres to the NoSQL movement even though it supports ACID Transactions and SQL as query language. In this way it's easy to start using it without having to learn too much new stuff.

Simple editor and analyzer of Petri nets. It allows you to build reachability tree with/without instant transitions and Markov chains. It is also possible to set transition distributions and set all the parameters of the current distribution. This project was made as a course project at NTUU "KPI" during attending classes "Computer modelling". Feel free to make any changes to the current version or ask me if you have any question.
