    BlueSky Open Air Traffic Simulator

    BlueSky Open Air Traffic Simulator

    BlueSky Open Air Traffic sim, (Windows/Linux/Mac, Python 2.x based)

    BlueSky is an Open Air Traffic Simulation for research purposes. It includes only open, license free data for navigation and aircraft performance but is also compatible with BADA 3. Can be used for ATC research or any other aviation or air transport related simulation studies. Is also able to visualize ADS-B traffic. BlueSky commands, and thus the scenario files, are compatible with the TMX simulator in use by NLR and NASA. BlueSky is originally developed, and still moderated, by prof. ...

    Open source 3D Matlab Isogeometric Analysis Code

    Isogeometric analysis (IGA) is a fundamental step forward in computational mechanics that offers the possibility of integrating methods for analysis into Computer Aided Design (CAD) tools and vice versa. The benefits of such an approach are evident, since the time taken from design to analysis is greatly reduced leading to large savings in cost and time for industry. The tight coupling of CAD and analysis within IGA requires knowledge from both fields and it is one of the goals of the...

    fPotencia

    fPotencia

    Power flow library in C++

    fPotencia is the fruit of free time and passion for power systems simulation. After observing the lack of ready-to-implement libraries for power system analisys, and that the existing ones focus on command line workflow, I decided myself to start a project to fill the gap. Since Power system simulations have started needing to be executed in parallel, the old C-like designs are outdated; modular design is now needed to launch many simulations at the same time based on a base circuit. ...

    Command Centre

    Free to join for developers who support the Free Software Foundation cause. This is my research project from 2003, which I recently updated with acceleration- and console changes (Surround Sound, Doppler Effects, Device Updates, Physics) in a long weekend but project should be considered abandoned. Additionally, the Performer libraries have been abandoned by Silicon Graphics.

    WISP

    Weighted Implementation of Suboptimal Paths (WISP)

    UPDATE: LATEST VERSION AT http://git.durrantlab.com//jdurrant/wisp Allostery can occur by way of subtle cooperation among protein residues (e.g., amino acids) even in the absence of large conformational shifts. Dynamical network analysis has been used to model this cooperation, helping to computationally explain how binding to an allosteric site can impact the behavior of a primary site often many angstroms away. Traditionally, computational efforts have focused on the most optimal path...

    Osmotic Pressurization Dynamics

    Calculates dynamics of osmosis-based pressure generation using PEG.

    This MATLAB script calculates pressure as a function of time inside a submerged membrane-bound compartment containing an aqueous PEG solution as an osmotic driver. It can also be used to calculate a membrane's hydraulic permeability by fitting experimental data. The model used accounts for the dilution effects caused by the compartment's expansion. All of this project's resources can be found in the "Files" section.
