  1. 1. Topics in Distributed Algorithms: On TDMA for Ad Hoc Networks and Coded Atomic Storage Algorithms

    Författare :Thomas Petig; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fault-Tolerance; TDMA; Message Passing; Self-Stabilization; Distributed Algorithm; Wireless Networks; Time Division Multiple Access; Shared Memory; Privacy;

    Sammanfattning : Distributed algorithms run on a network of nodes. The nodes are runningconcurrently and are independent from each other. Furthermore, they have their own instructions and information. In this context, the challenges are to show thatthe algorithm is correct, regardless of computational, or communication delays. LÄS MER

  3. 2. Synchronization and Communication Results in Safety-Critical Real-Time Systems

    Författare :Henrik Lönn; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; scheduling; TDMA; fault tolerance; membership agreement; safety-critical; atomic broadcast; embedded systems; clock synchronization; distributed real-time systems;

    Sammanfattning : A growing number of industrial control applications employ computer control to provide enhanced functionality and reduced cost. Many of these applications are safety-critical and require fault-tolerant techniques to provide an adequate level of safety. LÄS MER

  4. 3. Hygroscopic Growth of Atmospheric Aerosol Particles and Its Relation to Nucleation Scavenging in Clouds

    Författare :Birgitta Svenningsson; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aerosol formation; atmospheric aerosols; hygroscopic growth; nucleation scavenging; cloud; water activity; external mixing; tandem differential mobility analyser; Kärnfysik; cloud condensation nuclei spectra; Nuclear physics; TDMA; Fysicumarkivet A:1997:Svenningsson; inorganic salts;

    Sammanfattning : Aerosol particles in the atmosphere are important in several aspects. Some major aerosol constituents that are deposited in ecosystems are acidic or fertilisers and some minor or trace constituents are toxic. LÄS MER

  5. 4. Interference Rejection and Channel Detection in Mobile Communication

    Författare :Fredrik Nordström; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; detection of abrupt changes; WCDMA; Viterbi decoder; Kalman filter; co-channel interference; TDMA; EDGE; Mathematics; Matematik;

    Sammanfattning : This thesis is devoted to statistical problems in mobile communication, in particular disturbance rejection and change detection are studied. Co-channel interference is a significant problem for systems based on TDMA, e.g. EDGE. LÄS MER

  7. 5. Fine and Ultrafine Particles from Combustion Sources - Investigations with In-situ Techniques

    Författare :Joakim Pagels; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pollution control; Environmental technology; Teknik; Technological sciences; Indoor Air; In-Situ Measurement; Biomass Combustion; Morphology; Hygroscopic Growth; Volatility; TDMA; APS; ELPI; Respiratory Deposition; Fine Particles; Miljöteknik; kontroll av utsläpp; Ultrafine Particles;

    Sammanfattning : Fine airborne particles are associated with adverse health effects in the human population. The aim of this research was to develop and evaluate methods for in-situ characterisation of fine and ultrafine particles and to determine their deposition in the human airways. LÄS MER
