  1. 11. Designs and Analyses in Structured Peer-To-Peer Systems

    Författare :Sameh El-Ansary; RISE; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Peer-to-Peer (P2P) computing is a recent hot topic in the areas of networking and distributed systems. Work on P2P computing was triggered by a number of ad-hoc systems that made the concept popular. Later, academic research efforts started to investigate P2P computing issues based on scientific principles. LÄS MER

  3. 12. Resource Augmentation for Performance Guarantees in Embedded Real-time Systems

    Författare :Abhilash Thekkilakattil; Sasikumar Punnekkat; Radu Dobrin; Tullio Facchinetti; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Real-time scheduling policies have been widely studied, with many known schedulability and feasibility analysis techniques for different task models, that have advanced the state-of-the-art. Most of these techniques are typically derived under the assumption of negligible runtime overheads which may not be realistic for modern embedded real-time systems, and hence potentially compromises the guarantees on their correct behaviors.

  4. 13. Fusing Domain Knowledge with Data : Applications in Bioinformatics

    Författare :Claes Andersson; Jan Komorowski; Mats Gustafsson; Yves Moreau; Uppsala universitet; []
    Nyckelord :Bioinformatics; cell cycle; cancer chemotherapy; predictive tests; performance estimation; bioinformatics; Bioinformatik;

    Sammanfattning : Massively parallel measurement techniques can be used for generating hypotheses about the molecular underpinnings of a biological systems. This thesis investigates how domain knowledge can be fused to data from different sources in order to generate more sophisticated hypotheses and improved analyses. LÄS MER

  5. 14. Fundamental Bounds on Performance of Periodic Electromagnetic Radiators and Scatterers

    Författare :Andrei Ludvig-Osipov; B. Lars G. Jonsson; Christophe Caloz; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Q-factor; bandwidth; antenna arrays; periodic structures; physical bounds; physical limitations; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In this thesis, the optimal bandwidth performance of periodic electromagnetic radiators and scatterers is studied. The main focus is on the development and application of methods to obtain fundamental physical bounds, relating geometrical parameters, frequency bandwidth, efficiency and radiation characteristics of periodic electromagnetic structures.

  7. 15. Analysis of Some Methods for Identifying Dynamic Errors-in-variables Systems

    Författare :Mei Hong; Torsten Söderström; Magnus Jansson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; errors-in-variables; least squares; instrumental variable; maximum likelihood; bias compensated least squares; bias eliminating least squares; Frisch scheme; higher-order statistics; accuracy analysis; periodic data; Signal processing; Signalbehandling;

    Sammanfattning : A system where errors or noises are present on both the inputs and the outputs is called an errors-in-variables (EIV) system. EIV systems appear in industrial and agricultural processes, medical sciences, economical systems, biotechnology, as well as in many other areas. LÄS MER
