  2. 1. Quality issues in Internet packet forwarding

    Author : Ulf Bodin; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Abstract : This thesis addresses quality issues in Internet Protocol (IP) packet forwarding. In IP networks, queue mechanisms and scheduling can be used to construct multiple forwarding behaviors. Thereby, both relative and independent services can be offered to Internet users. Independent services offer forwarding qualities known beforehand. READ MORE

  4. 2. Improving TCP Performance in Wireless Multi-hop Networks : Design of Efficient Forwarding and Packet Processing Techniques

    Author : Jonas Karlsson; Andreas Kassler; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TCP; transport protocols; packet aggregation; multi path routing; wireless mesh networks; Computer Science; Datavetenskap;

    Abstract : Due to the high availability of cheap hardware, wireless multi-hop networks and in particular Wireless Mesh Networks (WMNs) are becoming popular in more and more contexts. For instance, IEEE 802.11 based WMNs have already started to be deployed as means to provide Internet access to rural areas in the developing world. READ MORE

  5. 3. Input-Output Stability Analysis of Networked Control Systems

    Author : Johannes Nygren; Kristiaan Pelckmans; Torkel Glad; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; L2-stability; quantization; delay; packet dropouts; switching systems; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : The main focus of the thesis is to derive stability criteria for networked control system (NCS) models featuring imperfections such as time-varying and constant delays, quantization, packet dropouts, and non-uniform sampling intervals. The main method of proof is based on matrix algebra, as opposed to methods using Lyapunov functions or integral quadratic constraints (IQC). READ MORE

  6. 4. Coding Speech for Packet Networks

    Author : Jonas Lindblom; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; packet loss concealment; voice over IP; speech coding; harmonic modeling; vector quantization; sinusoidal modeling; Gaussian mixture modeling; bounded support; frame erasure; variable dimension;

    Abstract : The topic of this thesis is speech coding for packet networks. Problems related to the use of packet networks for voice communication are addressed. Real-time voice communication is for example very delay sensitive; if the total end-to-end delay in a telephone session grows large, it is perceived as annoying. READ MORE

  7. 5. Electron Wave Packet Dynamics on the Attosecond Time Scale

    Author : Kathrin Klünder; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photoionization; Single attosecond pulses; Attosecond pulse trains; Electron wave packet; Electron dynamics; Interferometry; Photoemission time delay; Fysicumarkivet A:2012:Klünder; Stark spectroscopy;

    Abstract : One objective of attosecond science is to study electron dynamics in atoms and molecular systems on their natural time scale. This can be done using attosecond light pulses. READ MORE
