  2. 1. IT Dependability Management in Governmental Organisations

    Author : Kim Weyns; Institutionen för datavetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dependability; IT management; Risk management; Information safety; Emergency management; Maturity models; Software reliability modelling; Service level agreements;

    Abstract : As our dependence on IT systems increases, evaluating the dependability of critical IT systems becomes more important. This is especially true for systems that are critical in a crisis situation and whose dependability is an important factor in an organisation's capability to resolve a crisis. READ MORE

  4. 2. Dependability of IT Systems in Emergency Situations – Theory and Practice

    Author : Kim Weyns; Institutionen för datavetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dependability; IT Systems; Emergency Management; Markov Models; Sensitivity Analysis; Swedish Municipalities;

    Abstract : As our dependence on IT systems increases, evaluating the dependability of critical IT systems becomes more important. One of the main challenges in software reliability engineering is the sensitivity of software systems to a changing usage. READ MORE

  5. 3. Types for Crash Preventionn

    Author : Lars Pareto; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; reliability; dependability; concurrent programming; denotational semantics; real-time systems and embedded systems; data-flow; dynamic storage management; applicative functional programming languages ; type systems;

    Abstract : This thesis seeks to strengthen the capabilities of static polymorphic type-checking (as known from typed lambda calculus and functional programming) to allow a larger class of programming errors to be caught at compile time: the goal is to not only prevent illegal uses of data, but to also errors that lead to busy-loops, deadlocks, stack-overflows and heap-overflows. The thesis exploits that, for recursive programs, many correctness properties (including freedom from errors leading to busy-loops, etc. READ MORE

  6. 4. Systems Dependability Engineering for Wind Power Applications : Challenges, Concepts, and System-Level Methodologies

    Author : Idriss El-Thalji; Anders Karlsson; Linnéuniversitetet; []
    Keywords : System Dependability; Systems Engineering; Terotechnology; Terotechnology; Systemekonomi;

    Abstract : Complexity and uncertainty have impacted wind power systems and their applications.Commercial wind power asset exhibits complex system behaviour due tostochastic loading characteristics of its installation context. However, differentstakeholders’ practices in whole life cycle processes try to treat multi-disciplinarycomplexity issues. READ MORE

  7. 5. Dependability and maintenance analysis of railway signalling systems

    Author : Amparo Morant; Peter Söderholm; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Abstract : Railway signalling systems are composed of several different systems; each has its own purpose, but the main functionality of the overall system is determined by the interoperability between them. Railway signalling systems ensure the safe operation of the railway network, and their reliability and maintainability directly affect the capacity and availability of the railway network, in terms of both infrastructure and trains.
