  1. 1. Performance Guarantees for Physical Layer Authentication in Mission-Critical Communications

    Författare :Henrik Forssell; Ragnar Thobaben; Stefano Tomasin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physical layer authentication; mission-critical communica- tions; worst-case performance; queueing delay performance; stochastic net- work calculus; optimal attack strategies.; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : As the application areas for wireless communications are expanding, we also see new security vulnerabilities arise due to the open nature of the wire- less medium. One particularly challenging problem is how to guarantee the security of emerging mission-critical communications, e.g. LÄS MER

  2. 2. Processor Pipelines and Static Worst-Case Execution Time Analysis

    Författare :Jakob Engblom; Peter Puschner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information technology; Informationsteknik; Computer Systems; Datorteknik;

    Sammanfattning : Worst-Case Execution Time (WCET) estimates for programs are necessary when building real-time systems. They are used to ensure timely responses from interrupts, to guarantee the throughput of cyclic tasks, as input to scheduling and schedule analysis algorithms, and in many other circumstances.

  3. 3. A Modular Tool Architecture for Worst-Case Execution Time Analysis

    Författare :Andreas Ermedahl; Hans Hansson; Reinhard Wilhelm; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer engineering; Datorteknik; Computer Systems; Datorteknik;

    Sammanfattning : Estimations of the Worst-Case Execution Time (WCET) are required in providing guarantees for timing of programs used in computer controlled products and other real-time computer systems. To derive program WCET estimates, both the properties of the software and the hardware must be considered. LÄS MER

  4. 4. Aeroelastic Concepts for Flexible Aircraft Structures

    Författare :Sebastian Heinze; Dan Borglund; Rick Lind; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aeroelasticity; active aeroelastic aircraft structures; aeroelastic control; wind-tunnel testing; flutter analysis; robust flutter analysis; worst-case configuration; Vehicle engineering; Farkostteknik;

    Sammanfattning : In this thesis, aeroelastic concepts for increased aircraft performance are developed and evaluated. Active aeroelastic concepts are in focus as well as robust analysis concepts aiming at efficient analysis using numerical models with uncertain or varying model parameters. LÄS MER

  5. 5. An ALARP Stop-Test Decision for the Worst-Case Timing Characteristics of Safety-Critical Systems

    Författare :Mahnaz Malekzadeh; Sasikumar Punnekat; Iain Bate; Hans Hansson; Karl Meinke; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Sammanfattning : Safety-critical systems are those in which failure can lead to loss of people’s lives, or catastrophic damage to the environment. Timeliness is an important requirement in safety-critical systems, which relates to the notion of response time, i.e., the time a system takes to respond to stimuli from the environment. LÄS MER
