  1. 16. View Integration in Conceptual Database Design : Problems, Approaches and Solutions

    Författare :Peter Bellström; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information Systems; Informatik;

    Sammanfattning : View integration is a complex and time-consuming task because there are several problems that need to be addressed. Two such problems are conflict identification and conflict resolution. Conflicts occur because end users may define concepts on different levels of abstraction and because end users may name concepts differently. LÄS MER

  3. 17. A functional approach to heterogeneous computing in embedded systems

    Författare :Markus Aronsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Developing programs for embedded systems presents quite a challenge; not only should programs be resource efficient, as they operate under memory and timing constraints, but they should also take full advantage of the hardware to achieve maximum performance. Since performance is such a significant factor in the design of embedded systems, modern systems typically incorporate more than one kind of processing element to benefit from specialized processing capabilities.

  4. 18. Scheduling and Optimization of Fault-Tolerant Embedded Systems

    Författare :Viacheslav Izosimov; Zebo Peng; Petru Eles; Anton Cervin; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Embedded systems; Real-Time systems; Design optimization; Fault tolerance; Transient faults; Soft errors; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : Safety-critical applications have to function correctly even in presence of faults. This thesis deals with techniques for tolerating effects of transient and intermittent faults. Reexecution, software replication, and rollback recovery with checkpointing are used to provide the required level of fault tolerance. LÄS MER

  5. 19. Real-Time Services in Packet-Switched Networks for Embedded Applications

    Författare :Xing Fan; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; embedded systems; real-time communication; packet-switching; swithed Ethernet; FCFS and EDF scheduling; schedulability analysis; active networking; protocol overhead; Computer science; Datalogi; Computer science; Datavetenskap;

    Sammanfattning : Embedded applications have become more and more complex, increasing the demands on the communication network. For reasons such as safety and usability, there are real-time constraints that must be met. Also, to offer high performance, network protocols should offer efficient user services aimed at specific types of communication. LÄS MER

  7. 20. On Provably Correct Decision-Making for Automated Driving

    Författare :Yuvaraj Selvaraj; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; deductive verification; formal methods; supervisory control theory; formal verification; Automated driving; model checking; hybrid systems.; decision-making;

    Sammanfattning : The introduction of driving automation in road vehicles can potentially reduce road traffic crashes and significantly improve road safety. Automation in road vehicles also brings several other benefits such as the possibility to provide independent mobility for people who cannot and/or should not drive. LÄS MER
