    OpenCMISS-Zinc

    OpenCMISS-Zinc

    A Library for Interactive Modelling and Visualisation

    The OpenCMISS-Zinc Library (opencmiss.org/zinc), or Zinc, is a software library for building interactive graphical modelling and visualisation applications. Models are represented in Zinc as mathematical fields defined over domains, including finite elements with support for high-order basis functions, complex parameter mappings and time variation, and image-based fields. Further fields can be defined by mathematical expressions and algorithms on existing fields, including image processing filters. Zinc model data structures are dynamic, supporting interactive applications which programmatically create, destroy and modify parts of models.

    42

    Simulation for spacecraft attitude control system analysis and design

    42 is a comprehensive general-purpose simulation of spacecraft attitude and orbit dynamics. Its primary purpose is to support design and validation of attitude control systems, from concept studies through integration and test. 42 accurately models multi-body spacecraft attitude dynamics (with rigid and/or flexible bodies), and both two-body and three-body orbital flight regimes, modelling environments from low Earth orbit to throughout the solar system. 42 simulates multiple spacecraft concurrently, facilitating studies of rendezvous, proximity operations, and precision formation flying. It also features visualization of spacecraft attitude.

    Emulator of EPOS-73

    The behavioral model of the old Soviet calculator EPOS-73

    This project introduces a console application designed for functional and behavioral emulation of the old Soviet calculator EPOS-73 (ЭПОС-73) also known as Elektronika B3-11 (Электроника Б3-11). The project is conceived as an auxiliary for verification of the switch-level simulator based on Verilog HDL of the said apparatus. Calculator model EPOS-73 is interesting in that it was one of the first models of Soviet computing performed at LSI, that were fully designed by Soviet engineers. It was used a set of four LSIs series K1ZHG451...4 (К1ЖГ451...4) or later designation K145HK1...4 (К145ХК1...4). The choice of this calculator as an object of modeling is due to the presence of (miraculously survived to this day) a sufficient set of design documentation for the technology applied in its LSIs, including a technical description of the device, revealing its calculating algorithms. The project is intended for research and education purposes.
