  1. 1. On-demand Restricted Delegation : A Framework for Dynamic, Context-Aware, Least-Privilege Delegation in Grids

    Författare :Mehran Ahsant; Lennart Johnsson; Marty Humphrey; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Grid Security; Restricted and Context-Aware Delegation; Delegation Protocol; On-demand Delegation; Dynamic Trust Federation; Grid Interoperability; Credential Mapping; Computer science; Datalogi;

    Sammanfattning : In grids, delegation is a key facility that can be used to authenticate and authorize requests on behalf of disconnected users. In current grid systems,delegation is either performed dynamically, in an unrestricted manner, or by a secure but static method. LÄS MER

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

    Författare :Risat Pathan; Chalmers University of Technology; []
    Nyckelord :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.

  3. 3. Cold feet in children with neurological disorders

    Författare :Lena Svedberg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Skin temperature; Acupuncture; Autonomic dysfunction; Cerebral palsy; Spinal cord disorders; Pain; Constipation; Well-being; Parental health; Parental mood; Restricted time; Services support; Sleeping disorders;

    Sammanfattning : These studies focused on presence of cold feet in children with neurological disorders and raised the questions: Does acupuncture affect skin temperature? Are cold feet a general symptom in children with neurological disorders? Are cold feet associated with other symptoms? What are the moods, health, and daily life experiences of these children’s parents? Study I assessed effects of acupuncture on skin temperature in children with neurological disorders. The study was of pilot character, to determine if further investigation in a larger, well-characterised group could be worthwhile. LÄS MER

  4. 4. Memory Efficient Hard Real-Time Garbage Collection

    Författare :Tobias Ritzau; Peter Fritzson; Roger Henriksson; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; hardware progresses; programming languages; garbage collector; real-time reference counting; object ownership; static garbage collector; embedded systems; Computer science; Datavetenskap;

    Sammanfattning : As the development of hardware progresses, computers are expected to solve increasingly complex problems. However, solving more complex problems requires more complex software. To be able to develop these software systems, new programming languages with new features and higher abstraction levels are introduced. LÄS MER

  5. 5. Probabilistic Sequence Models with Speech and Language Applications

    Författare :Gustav Eje Henter; W. Bastiaan Kleijn; Arne Leijon; Gernot Kubin; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Time series; acoustic modelling; speech synthesis; stochastic processes; causal-state splitting reconstruction; robust causal states; pattern discovery; Markov models; HMMs; nonparametric models; Gaussian processes; Gaussian process dynamical models; nonlinear Kalman filters; information theory; minimum entropy rate simplification; kernel density estimation; time-series bootstrap;

    Sammanfattning : Series data, sequences of measured values, are ubiquitous. Whenever observations are made along a path in space or time, a data sequence results. To comprehend nature and shape it to our will, or to make informed decisions based on what we know, we need methods to make sense of such data. LÄS MER
