  1. 36. Enhancing the Performance of Distributed Real-time Systems

    Författare :Hoai Hoang; Magnus Jonsson; Bertil Svensson; Luís Almeida; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Switched Ethernet; Real-Time Communication; EDF scheduling; Reducation of delay and jitter; Computer science; Datalogi;

    Sammanfattning : Advanced embedded systems can consist of many sensors, actuators and processors that are deployed on one or several boards, while having a demand of interacting with each other and sharing resources. Communication between different components usually has strict timing constraints. LÄS MER

  2. 37. Detection of Myocardial Ischemia using Real-Time Myocardial Contrast Echocardiography

    Författare :Petri Gudmundsson; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardial contrast echocardiography; MCE; stress echocardiography; adenosine; perfusion; real-time; visual; quantative; wall motion; power modulation; bedside; SPECT; coronary insufficiency;

    Sammanfattning : Diagnostisering av syrebrist i hjärtmuskeln med hjälp av kontrastförstärkt ultraljudsundersökning av hjärtmuskelns genomblödning. Ultraljudsundersökning av hjärtat (ekokardiografi) används mycket inom hjärtsjukvården idag, oftast för att utreda hjärtats och hjärtklaffarnas anatomi och funktion. LÄS MER

  3. 38. 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. 39. Scheduling techniques to improve the worst-case execution time of real-time parallel applications on heterogeneous platforms

    Författare :Petros Voudouris; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel applications; global; work-conserving; federated; heterogeneous multiprocessors; response time; Hard real-time systems; unrelated model; DAG; makespan;

    Sammanfattning : The key to providing high performance and energy-efficient execution for hard real-time applications is the time predictable and efficient usage of heterogeneous multiprocessors. However, schedulability analysis of parallel applications executed on unrelated heterogeneous multiprocessors is challenging and has not been investigated adequately by earlier works. LÄS MER

  5. 40. Real-Time Communication over Switched Ethernet with Resource Reservation

    Författare :Mohammad Ashjaei; Thomas Nolte; Moris Behnam; Luis Almeida; Thilo Sauter; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-time communication; Response time analysis; Computer Science; datavetenskap;

    Sammanfattning : Due to the need for advanced computer-controlled functionality in distributed embedded systems the requirements on network communication are becoming overly intricate. This dissertation targets the requirements that are concerned with real-time guarantees, run-time adaptation, resource utilization and flexibility during the development. LÄS MER
