  1. GAFT Generalization: A Principle and Model of Active System Safety 

    Schagaev I.; Gutknecht J. (2024)
    Software Design for Resilient Computer Systems, Third Edition
    Fault tolerance so far was considered as a property of a system. In fact and instead we introduce A Generalized Algorithm of Fault Tolerance (GAFT) that consider fault tolerance as a system process. There is no doubt we have to analyze GAFT implementation using redundancy types of computer systems. Properties of GAFT implementation impact on overall performance of the system, coverage of faults and ability of reconfiguration. Clear that ...

  2. Active System Control: Language Implementation Aspects 

    Schagaev I.; Gutknecht J.; Zouev E. (2024)
    Software Design for Resilient Computer Systems, Third Edition
    From analysis of results of Active System Control Project extension further analysis of on-board-on-ground instruments is discussed. Analysis of potential development and actors in implementation is presented. Two types of interaction between moving object and base should be supported: real-time without and with human. Comparison of Java, Juice and Oberon as a potential framework for implementation is given. Shown that Oberon and Juice ...

  3. Recovery: Searching and Monitoring of Correct Software States 

    Schagaev I.; Gutknecht J. (2024)
    Software Design for Resilient Computer Systems, Third Edition
    The last of the three GAFT processes is called recovery and recovery monitoring. After the detection of an error and possible reconfiguration, the last step is recovering the software, which means that the effect of the error on the software must be eliminated. In line with the previous chapters and (Sogomonian and Scha- gaev in Hardware and software fault tolerance of computer systems. Avtomatika i Telemekhanika, pp. 3–39, 1988 [1]; ...

  4. Generalized Algorithm of Fault Tolerance (GAFT) 

    Schagaev I.; Gutknecht J. (2024)
    Software Design for Resilient Computer Systems, Third Edition
    Fault tolerance so far was considered as a property of a system. In fact and instead we introduce A Generalized Algorithm of Fault Tolerance (GAFT) that considers property of fault tolerance as a system process. GAFT implementation analysis—if we want to make it rigorous—should be using classification of redundancy types. Various redundancy types have different “power” of use at various steps of GAFT. Properties of GAFT implementation ...

  5. Fractional statistics, gauge invariance and anomalies in condensed matter physics 

    Fröhlich J. (2024)
    Encyclopedia of Condensed Matter Physics
    A general formalism, dubbed “Gauge Theory of States/Phases of Matter,” which serves to partially classify electronic states in systems of condensed matter physics, and the theory of fractional statistics in low-dimensional systems are reviewed. Applications to the quantum Hall effect, to 2D time-reversal invariant insulators, and to certain 2D wave guides with chiral edge modes are sketched. The theory of 3D topological insulators, including ...
