  • ransfoil Icon


    console to calculate airflow around an airfoil based on RANS approach

    RANSFOIL is a console program to calculate airflow field around an isolated airfoil in low-speed, subsonic, transonic or supersonic regime by numerically solving the Reynolds averaged Navier-Stokes (RANS) equations using mature computational fluid dynamics (CFD) method. As postprocess results, the aerodynamic parameters of the airfoil, e.g., lift coefficient and drag coefficient, can be integrated from the airflow distribution near wall boundary. In addition, the coupling between airflow and heat transfer and the effect of surface roughness on near wall flow are considered by this program, it can be used for engineering calculation of the friction drag and heat transfer coefficients on airfoil surface. RANSFOIL reads airfoil coordinates from a 1D XYZ file as only input, then outputs grid and solution files in 2D PLOT3D format to record grid coordinates and airflow data and a report file to show aerodynamic parameters.

  • autoCode4

    Synthesizing embedded control software from formal specifications

    autoCode4 is an engine that synthesizes controllers from formal specifications described under a subset of linear temporal logic (LTL). Importantly, it synthesizes synchronous dataflow controllers (in Lustre or in Ptolemy II form) and maintains requirement-to-code traceability. Such feature is mandated in developing safety-critical systems and are considered essential for specification validation or integrating manual implementation such as legacy code. The LTL specification captures the desired behavior of a controller where the environment takes the first move (i.e., sense/input then react/output), so the synthesized controller can be viewed as a Mealy machine. A step-by-step tutorial is available within the software package.

  • Pharos Icon


    RTOS for Secure Systems

    Pharos is a Real-Time Operating System designed for Secure Systems with the following characteristics: -Security: With space partitions and enhanced time partitioning. Each partition protected with hardware MMU/MPU and operating in user mode. -Quality: Low cyclomatic, high comments, low nesting level, MISRA. -Mixed Criticality: Partition independence and isolation. Native support for sporadic, periodic and aperiodic threads under a fixed-priority preemptive scheduler, including execution time protection (threads are not allowed to run for more time than they are configured to). -Determinism: Hard real-time determinism, most calls areO(1) and very few cases are O(Log(N)) - they are well indentified in the user manual. Pharos takes ARINC and moves it one step further, improving responsiveness and isolation. Supports ARM R5, M4, 926EJ-S. We are a group of enthusiastic software developers that also implements client custom software. Contact:

    Math Expression Parser 4 Java

    Math Expression Parser 4 Java MEP4J is a high performance math expression strings parser for Java (J2SE >= 5). Compare its performance against similiar libraries and let me know your experince. The library manages the 5 operators (+, -, /, %, *) together with the following functions: - "abs" - "cos" - "sin" - "acos" - "asin" - "cosh" - "sinh" - "tan", - "tanh" - "atan" - "sqrt" - "cbrt" - "root" - "log" - "log10" - "log1p" - "exp" - "expm1" - "atan2" - "pow" The library supports variables (case insensitive), custom and pre-loaded ("e" and "pi"). Example: int num_variations = 100; int init_value = 10; MathParser mathParser = new MathParser(); mathParser.addVariable("x", init_value); mathParser.parse("2 + (7 - 5) * 3.14159 * pow(x, (12-10)) + sin(-3.141)"); for(int i = init_value; i < num_variations; ++i) { Double result = mathParser.execute(); mathParser.addVariable("x", i); }
