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

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

   Abstract : 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. READ MORE

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

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

   Abstract : 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. READ MORE

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

   Author : Birgitta Svenningsson; Kärnfysik; []
   Keywords : 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;

   Abstract : 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. READ MORE

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

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

   Abstract : 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. READ MORE

7. 5. Topics in Distributed Algorithms: On Wireless Networks, Distributed Storage and Streaming

   Author : Thomas Petig; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Message Passing; Wireless Networks; Time Division Multiple Access; Shared Memory; Fault-Tolerance; Streaming; NP-Hardness; Distributed Algorithm; Optimisation; TDMA;

   Abstract : Distributed algorithms are executed on a set of computational instances. Werefer to these instances as nodes. Nodes are runningconcurrently and are independent from each other. Furthermore, they have their own instructions and information. READ MORE
