    Abstract : In the past decade, the integration of spatiotemporal constraints into control systems has emerged as a crucial necessity, driven by the demand for enhanced performance, guaranteed safety, and the execution of complex tasks. Spatiotemporal constraints involve criteria that are dependent on both space and time, which can be represented by time-varying constraints in nonlinear control systems. READ MORE

  4. 7. Adaptive Middleware for Self-Configurable Embedded Real-Time Systems : Experiences from the DySCAS Project and Remaining Challenges

    Author : Magnus Persson; Martin Törngren; DeJiu Chen; Thiemo Voigt; KTH; []
    Keywords : adaptivity; embedded real-time systems; DySCAS; DyLite; quality of service QoS ; load balancing; resource constraints; model-based design; component-based design; software architecture; adaptive middleware;

    Abstract : Development of software for embedded real-time systems poses severalchallenges. Hard and soft constraints on timing, and usually considerableresource limitations, put important constraints on the development. Thetraditional way of coping with these issues is to produce a fully static design,i.e. READ MORE

    Author : Kristina Kunert; Magnus Jonsson; Elisabeth Uhlemann; Eduardo Tovar; Högskolan i Halmstad; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 9. Scheduling and Optimization of Fault-Tolerant Distributed Embedded Systems

    Author : Viacheslav Izosimov; Zebo Peng; Petru Eles; Paul Pop; Krishnendu Chakrabarty; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Safety-critical applications have to function correctly and deliver high level of quality-ofservice even in the presence of faults. This thesis deals with techniques for tolerating effects of transient and intermittent faults. READ MORE

  7. 10. Timing Modes for the MAX IV Storage Rings

    Author : Teresia Olsson; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Synchrotron light storage rings; timing experiments; ultralow emittance; harmonic cavities; fill patterns; PPRE; PSB; Fysicumarkivet A:2018:Olsson;

    Abstract : The MAX IV facility includes two storage rings, operated at 1.5 and 3 GeV energy, for the purpose of producing high-brilliance synchrotron radiation for users. The 1.5 GeV ring replaces the previous MAX II and MAX III storage rings as a source of UV and soft X-rays, whereas the 3 GeV ring is optimized for hard X-rays. READ MORE
