  1. 11. Few is Just Enough! : Small Model Theorem for Parameterized Verification and Shape Analysis

    Författare :Frédéric Haziza; Parosh Aziz Abdulla; Tomáš Vojnar; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; program verification; model checking; parameterized systems; infinite-state systems; reachability; approximation; safety; tree systems; shape analysis; small model properties; view abstraction; monotonic abstraction; Computer Science; Datavetenskap;

    Sammanfattning : This doctoral thesis considers the automatic verification of parameterized systems, i.e. systems with an arbitrary number of communicating components, such as mutual exclusion protocols, cache coherence protocols or heap manipulating programs. The components may be organized in various topologies such as words, multisets, rings, or trees. LÄS MER

  2. 12. Functional Programming for Embedded Systems

    Författare :Abhiroop Sarkar; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Embedded Systems; Timing; Concurrency; Functional Programming; Virtual Machine; Language Runtime;

    Sammanfattning : Embedded Systems application development has traditionally been carried out in low-level machine-oriented programming languages like C or Assembler that can result in unsafe, error-prone and difficult-to-maintain code. Functional programming with features such as higher-order functions, algebraic data types, polymorphism, strong static typing and automatic memory management appears to be an ideal candidate to address the issues with low-level languages plaguing embedded systems.

  3. 13. Vulnerability Analysis for Critical Infrastructures

    Författare :Yuning Jiang; Yacine Atif; Jianguo Ding; Manfred A. Jeusfeld; Birgitta Lindström; Christoffer Brax; Sokratis Katsikas; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; critical infrastructure cybersecurity; vulnerability assessment; vulnerability quantification; computational intelligence in cybersecurity; cyber-physical system; INF303 Informationssäkerhet; INF303 Information Security; INF301 Data Science; INF301 Data Science; Distribuerade realtidssystem DRTS ; Distributed Real-Time Systems;

    Sammanfattning : The rapid advances in information and communication technology enable a shift from diverse systems empowered mainly by either hardware or software to cyber-physical systems (CPSs) that are driving Critical infrastructures (CIs), such as energy and manufacturing systems. However, alongside the expected enhancements in efficiency and reliability, the induced connectivity exposes these CIs to cyberattacks exemplified by Stuxnet and WannaCry ransomware cyber incidents.

  4. 14. Preservation of Extra-Functional Properties in Embedded Systems Development

    Författare :Mehrdad Saadatmand; Mikael Sjödin; Antonio Cicchetti; Vittorio Cortellessa; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Software Engineering; Embedded Systems; Non-Functional Requirements; Extra-Functional Properties; Model-Driven Development; Trade-off analysis; Computer Science; datavetenskap;

    Sammanfattning : The interaction of embedded systems with their environments and their resource limitations make it important to take into account properties such as timing, security, and resource consumption in designing such systems. These so-called Extra-Functional Properties (EFPs) capture and describe the quality and characteristics of a system, and they need to be taken into account from early phases of development and throughout the system's lifecycle.

  5. 15. Integration of Enterprise Modeling and Model Driven Development : A Meta-Model and a Tool Prototype

    Författare :Iyad Zikra; Janis Stirna; Jelena Zdravkovic; Anne Persson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Model-Driven Development; MDD; Enterprise Modeling; EM; Meta-model; Prototype; Design Science; Tool Implementation; informationssystem; Information Systems;

    Sammanfattning : The use of models for designing and developing Information Systems (IS) has changed in recent years. Models are no longer considered a peripheral documentation medium that is poorly maintained and often neglected. LÄS MER
