  1. 1. Real-Time Workload Models : Expressiveness vs. Analysis Efficiency

    Författare :Martin Stigge; Wang Yi; Sanjoy Baruah; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-time systems; task models; EDF; fixed-priority scheduling; schedulability analysis; response-time analysis; abstraction refinement; Computer Science with specialization in Real Time Systems; Datavetenskap med inriktning mot realtidssystem;

    Sammanfattning : The requirements for real-time systems in safety-critical applications typically contain strict timing constraints. The design of such a system must be subject to extensive validation to guarantee that critical timing constraints will never be violated while the system operates. LÄS MER

  3. 2. Preemption-Delay Aware Schedulability Analysis of Real-Time Systems

    Författare :Filip Marković; Jan Carlson; Radu Dobrin; Björn Lisper; Enrico Bini; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-time systems; Scheduling; Schedulability analysis; Preemptions; Preemption delays; Embedded Systems; Preemptive scheduling; Response-time analysis; Cache-related preemption delay; Timing analysis; Worst-case execution time analysis; Limited-preemptive scheduling; Fixed preemption points; Computer Science; datavetenskap;

    Sammanfattning : Schedulability analysis of real-time systems under preemptive scheduling may often lead to false-negative results, deeming a schedulable taskset being unschedulable. This is the case due to the inherent over-approximation of many time-related parameters such as task execution time, system delays, etc. LÄS MER

  4. 3. Fault-Tolerance Strategies and Probabilistic Guarantees for Real-Time Systems

    Författare :Hüseyin Aysan; Sasikumar Punnekkat; Radu Dobrin; Hans Hansson; Petru Eles; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; embedded systems; real-time systems; fault tolerant design; real-time analysis; dependability analysis; Computer engineering; Datorteknik; Computer Science; datavetenskap;

    Sammanfattning : Ubiquitous deployment of embedded systems is having a substantial impact on our society, since they interact with our lives in many critical real-time applications. Typically, embedded systems used in safety or mission critical applications (e.g. LÄS MER

  5. 4. Sensitive Forensic DNA Analysis : Application of Pyrosequencing and Real-time PCR Quantification

    Författare :Hanna Andréasson; Marie Allen; Ulf Gyllensten; Pål Nyrén; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; forensic; sensitive DNA analysis; DNA quantification; mtDNA; Real-time PCR; Pyrosequencing; Genetik; Clinical genetics; Klinisk genetik;

    Sammanfattning : The field of forensic genetics is growing fast and the development and optimisation of more sensitive, faster and more discriminating forensic DNA analysis methods is highly important. In this thesis, an evaluation of the use of novel DNA technologies and the development of specific applications for use in forensic casework investigations are presented. LÄS MER

  7. 5. Architectures and Protocols for Performance Improvements of Real-Time Networks

    Författare :Kristina Kunert; Magnus Jonsson; Elisabeth Uhlemann; Eduardo Tovar; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-time communication; predictable deadline guarantees; real-time scheduling analysis; timing analysis; admission control; deterministic medium access; MAC; Quality of Service parameters; reliability; redundancy; retransmission scheme; ARQ; truncated ARQ; Automatic Repeat Request; wireless networks; IEEE 802.11; IEEE 802.15.4; fibre-optic networks; AWG; multichannel networks; industrial communications; embedded systems; Computer engineering; Datorteknik;

    Sammanfattning : When designing architectures and protocols for data traffic requiring real-time services, one of the major design goals is to guarantee that traffic deadlines can be met. However, many real-time applications also have additional requirements such as high throughput, high reliability, or energy efficiency. LÄS MER
