  1. 1. Modelling and Control Methods with Applications to Mechanical Waves

    Författare :Hans Norlander; Bengt Carlsson; Torsten Söderström; Jonas Sjöberg; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automatic control; pole placement; linearization; vibration control; distributed parameter systems; wave propagation; Automatic Control; Reglerteknik;

    Sammanfattning : Models, modelling and control design play important parts in automatic control. The contributions in this thesis concern topics in all three of these concepts.The poles are of fundamental importance when analyzing the behaviour of a system, and pole placement is an intuitive and natural approach for control design.

  3. 2. Viscoelastic Materials : Identification and Experiment Design

    Författare :Agnes Rensfelt; Torsten Söderström; Händel Peter; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; viscoelastic materials; complex modulus; system identification; optimal experiment design; distributed parameter systems; frequency domain identification; wave propagation; Automatic control; Reglerteknik; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : Viscoelastic materials can today be found in a wide range of practical applications. In order to make efficient use of these materials in construction, it is of importance to know how they behave when subjected to dynamic load. LÄS MER

  4. 3. Finding, extracting and exploiting structure in text and hypertext

    Författare :Ola Ågren; Jürgen Börstler; Frank Drewes; Maarten de Rijke; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Automatic propagation; CHiC; Data mining; Discrete data; Extraction; Hierarchies; ProT; Rank distribution; S²ProT; Spatial linking; Web mining; Web searching; Computer science; Datalogi; business data processing; administrativ databehandling;

    Sammanfattning : Data mining is a fast-developing field of study, using computations to either predict or describe large amounts of data. The increase in data produced each year goes hand in hand with this, requiring algorithms that are more and more efficient in order to find interesting information within a given time. LÄS MER

  5. 4. Methods for measurements and analyses of cracks in flexible pavements

    Författare :Petra Offrell; KTH; []
    Nyckelord :Cracking; Crack propagation; Data collection methods; Image analysis; Image processing; LTPP; Automatic identification systems; Flexible pavement; PAVUE; Laser RST; measures; characterisation; x-ray computerised tomography; asphalt; 3D analysis; top-;

    Sammanfattning : When cracking has propagated through the entire asphaltbound layers, water may ingress into the unbound layers andaccelerate the deterioration of the road structure. Knowledgeon where cracks initiate and how they propagate vertically istherefore of great practical importance. LÄS MER
