  1. 16. Functional modelling of the human timing mechanism

    Författare :Guy Madison; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Brain mechanisms; Brownian motion; drift; dynamical systems; fractal; human; Gaussian noise; Hurst exponent; time; time series analysis; timing; Psykologi; Psychology; Psykologi; fysiologi; Physiology;

    Sammanfattning : Behaviour occurs in time, and precise timing in the range of seconds and fractions of seconds is for most living organisms necessary for successful interaction with the environment. Our ability to time discrete actions and to predict events on the basis of prior events indicates the existence of an internal timing mechanism. LÄS MER

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

    Författare :Magnus Persson; Martin Törngren; DeJiu Chen; Thiemo Voigt; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 19. Differential Equations with Constraints

    Författare :Olivier Verdier; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : We study various differential equations subject to constraints. In the first part we study a partial differential equation, Burgers equation, subject to time-periodicity constraint. The forcing term is time-periodic and may be highly irregular. LÄS MER

  7. 20. Three Aspects of Real-Time Multiprocessor Scheduling: Timeliness, Fault Tolerance, Mixed Criticality

    Författare :Risat Pathan; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mixed-Criticality Systems; Fault-Tolerant Scheduling; Fixed Priority; Real-Time Systems; Global Multiprocessor Scheduling; Time Redundancy; Sporadic Tasks;

    Sammanfattning : The design of real-time systems faces two important challenges: incorporating more functions/services on existing hardware to make the system more attractive to the market, and deploying existing software on multiprocessors (e.g., multicore) to utilize moreprocessing power.
