  1. 16. Ultrasonic characterization of materials and multiphase flows

    Författare :Johan Carlson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : This thesis deals with three different applications of ultrasound measurement technology. In process industries like the mining industry, the oil and gas industry, and the paper pulp industry, multiphase flows play an important role. LÄS MER

  3. 17. Multifunctional composite materials : Design, manufacture and experimental characterisation

    Författare :Tony Carlson; Emile Smith Greenhalgh; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : The use of lightweight materials in structural applications is ever increasing. Today, lightweight engineering materials are needed to realise greener, safer and more competitive products. LÄS MER

  4. 18. Blind Adaptive Extraction of Impulsive Signatures from Sound and Vibration Signals

    Författare :Aziz Kubilay Ovacikli; Johan Carlson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : The two questions in science ``why" and ``how" are hereby answered in the context of statistical signal processing applied to vibration analysis and ultrasonic testing for fault detection and characterization in critical materials such as rolling bearings and thin layered media. Both materials are of interest in industrial processes. LÄS MER

  5. 19. Lönesättning i praktiken : En studie om chefers handlingsutrymme

    Författare :Elizabeth Neu; Carin Eriksson-Lindvall; Lars Engwall; Cecilia Lindholm; Jan Löwstedt; Uppsala universitet; []
    Nyckelord :Business studies; Företagsekonomi; Lönesättning; Individuell lönesättning; Handlingsutrymme; Struktureringsteori; Första linjens chef; Business Studies; företagsekonomi;

    Sammanfattning : Empirical studies of managers have shown that managerial work is characterized by a high level of social interaction (Carlson, 1951; Stewart, 1967; Mintzberg, 1973). Managerial work is often conducted face-to-face, and managers often perceive a need to react to the situations, problems and requirements of others. LÄS MER

  7. 20. Weighted multidimensional integral inequalities and applications

    Författare :Sorina Barza; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : In this thesis some new weighted integral inequalities for monotone functions in higher dimensions are proved. These results extend previous results in one dimension, and also those in higher dimensions for particular choices of the weights (power weights, etc.). All inequalities are sharp. LÄS MER
