  1. 1. Timing Predictability in Future Multi-Core Avionics Systems

    Author : Andreas Löfwenmark; Simin Nadjm-Tehrani; Risat Pathan; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Timing Predictability; WCET; WCRT; Fault Tolerance; Safety Critical; Avionics;

    Abstract : With more functionality added to safety-critical avionics systems, new platforms are required to offer the computational capacity needed. Multi-core platforms offer a potential that is now being explored, but they pose significant challenges with respect to predictability due to shared resources (such as memory) being accessed from several cores in parallel.

  2. 2. Aircraft Systems Modeling : Model Based Systems Engineering in Avionics Design and Aircraft Simulation

    Author : Henric Andersson; Petter Krus; Olof Johansson; Fredrik Berglund; Linköpings universitet; []
    Keywords : MBSE; MBD; Avionics; Simulation; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Aircraft developers like other development and manufacturing companies, are experiencing increasing complexity in their products and growing competition in the global market. One way to confront the challenges is to make the development process more efficient and to shorten time to market for new products/variants by using design and development methods based on models.

  3. 3. Optimisation methods for solving a large-scale avionics scheduling problem

    Author : Emil Karlsson; Elina Rönnberg; Kaj Holmberg; Simin Nadjm-Tehrani; Musliu Nysret; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Optimisation; Decomposition; Large-scale scheduling; Avionics scheduling;

    Abstract : Modern computer systems in aircraft are based on an integrated modular avionic architecture. In this architecture, software applications share hardware resources on a common avionic platform. Many functions in an aircraft are controlled by software and a failure in such software can have severe consequences. READ MORE

  4. 4. Thermal management of electronics in avionics applications

    Author : Jonas Johansson; Peter Leisner; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The development of electronic equipment towards minimizing of cost and size has lead to increased requirements on the cooling equipment for electronics. In avionics applications, constraints are put on all equipment regarding size, weight, and reliability. READ MORE

  5. 5. Thermal Fatigue Life Prediction of Solder Joints in Avionics by Surrogate Modeling : A Contribution to Physics of Failure in Reliability Prediction

    Author : Jonas Arwidson; Peter Leisner; Kouchi Zhang; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Manufacturers of aerospace, defense, and high performance (ADHP) equipment are currently facing multiple challenges related to the reliability of electronic systems. The continuing reduction in size of electronic components combined with increasing clock frequencies and greater functionality, results in increased power density. READ MORE
