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 MIGFEM is to provide a simple-to-understand IGA FEM code. The work is funded under the FP7 Initial Training Network Funding under grant number 289361 'Integrating Numerical Simulation and Geometric Design Technology.' If you use this code or inspired by it please cite the following reference in your work: VP Nguyen, C Anitescu, S Bordas, T Rabczuk.

realistic truck & car simulator, with OpenGL graphics
update: https://sourceforge.net/projects/newctruck3drally/ It's a 3D, physically realistic truck/car simulator, oriented to dirt tracks. This is subsancially kept as hystorical. The environment is a hilly terrain which can also be user-defined in the form of a Bitmap image file (where intensity of red component defines height). It's similar to the classic "Terep 2". Particular care for internal cam. Written in standard C. There's a Windows executable ready for use, but it's compilable and playable on all Linux, BSD, MacOSX systems. Official VIDEO presentation: http://www.youtube.com/watch?v=B74QvPGyBYM The physical simulation was written from 0 of course, so no external 'third-party' libraries are used; except GLUT+OpenGL for the graphical visualisation & good interactivity.

CNV prediction from Illumina genotyping data
CNVision is a Perl script that runs Illumina genotyping data (all chips from 300k to latest Omni) through PennCNV, QuantiSNPv2.3 and GNOSIS (an in-built algorithm). It merges the results and assesses the quality of the raw data. CNVision can also identify de novo CNVs in family-based data using a highly accurate algorithm that considers the possibility of CNVs in either parent based on the raw genotyping data. The script is optimized to work in a UNIX-based environment; it should work in Windows, however running the PennCNV component gives errors with the newer versions of PennCNV. CNVision was written to analyze data for the Simons Simplex Collection (SSC) autism data. A fill description of methods are given in the following paper which can be used to reference CNVision: http://www.ncbi.nlm.nih.gov/pubmed/21658581

ZUPT aided INS software components for an embedded platform
The project aim at developing open source software components for an embedded foot-mounted inertial navigation system. The platform is an Atmel AVR32UC3C2512c microcontroller with MPU9150 IMUs (previously Analog Devices iSensor 16367 IMU). However, the mechanization equations and filtering implementation should be independent of the hardware and easily compiled for other platforms. The project is a part of the larger OpenShoe project aimed at developing a full open source hardware and software embedded ZUPT aided INS implementation. Hardware and software documentation is found at the OpenShoe homepage. The work is a part of the research work carried out at the Signal Processing Lab, KTH Royal Institute of Technology, Stockholm, Sweden and the Statistical Signal Processing Lab, IISc, Bangalore, India. The initial work was primarily be carried out during the fall and winter of 2011-2012. Since then the code has been continuously updated.
vHDL Obfuscator is an small GUI to obfuscate and reformat HDL files
VHDL and Verilog HDL are standards languages for hardware description. Sometimes is necessary to share the source HDL file but maintaining a little level of control and protection of the intellectual property. This tool generate obfuscated code that is almost unreadable to humans, but is still readable to compilers and simulators. This tool use GHDL (https://sourceforge.net/projects/ghdl-updates/), HDLObf (https://sourceforge.net/projects/hdlobf/), Icarus Verilog (https://sourceforge.net/projects/iverilog/) and was created in Lazarus (http://www.lazarus-ide.org/)
Modular CNC software for Arduino controller
The goal of the project is the realization of a modular firmware that allows to control a CNC machine with different utensils. For instance, a CNC with a drill, with few changes can become a plotter with a pen or cutting machine to cut cardboard or stickers. In order to do that, we want project a CNC router with a mechanism that allows a fast utensil change and a controlling firmware which can use different utensils changing some configuration parameters.
A general recommender system with basic models and MRA
Multi-categorization Recommendation Adjusting (MRA) is to optimize the results of recommendation based on traditional(basic) recommendation models, through introducing objective category information and taking use of the feature that users always get the habits of preferring certain categories. Besides this, there are two advantages of this improved model: 1) it can be easily applied to any kind of existing recommendation models. And 2) a controller is set in this improved model to provide controllable adjustment range, which thereby makes it possible to provide optional modes of recommendation aiming different kinds of users.

XFEM implementation in MATLAB
The extended finite element method (XFEM) classified, one of the partition of unity method (PUM), allows discontinuities to be simulated independently of the mesh. This is possible by adding appropriate functions to the FE approximation basis, for example, the Heaviside function. The discontinuities can evolve in time, without a need for a conforming mesh. A MATLAB implementation of the XFEM written by VP Nguyen, is given here. The interaction of cracks and crack-inclusion interaction is modelled with XFEM framework. The elements intersected by discontinuity surface are sub-divided into quadrature subcells aligned with the discontinuity and higher order quadrature is adopted. The implementation is described in the following article: Meshless methods: a review and computer implementation aspects VP Nguyen, T Rabczuk, S Bordas, M Duflot, Mathematics and computers in simulation 79 (3), 763-813.
