  1. 1. Examining the competition for forest resources in Sweden using factor substitution analysis and partial equilibrium modelling

    Författare :Anna Olsson; Tommy Lundgren; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Sammanfattning : The overall objective of the thesis is to analyse the procurement competition for forestresources in Sweden. The thesis consists of an introductory part and two self-containedpapers. LÄS MER

  3. 2. Stainless steel plasticity : material modelling and structural applications

    Författare :Anders Olsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : The thesis addresses stainless steel in construction with focus on plasticity and shear resistance of welded girders respectively. In the area of plasticity it comprises an account of an experimental study with emphasis on phenomenological observations followed by theorethical modelling. LÄS MER

  4. 3. Digital holographic reconstructions of ultrasound from laser vibrometry recordings

    Författare :Erik Olsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : If sound and noise from an engine, say a lawn mower, is to be reduced, it is of advantage to know from which part of the machine the noise is coming. An interesting medical application for localization of sound sources is optoacoustic imaging of tissue. LÄS MER

  5. 4. Sound source localization from laser vibrometry recordings

    Författare :Erik Olsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : Acoustic holography deals with a typical inverse problem, to obtain the unknown from something that is known. From measurements of sound, most often using microphone arrays, reconstructions of the sound field are made in an attempt to find out what causes the sound. LÄS MER

  7. 5. Performance analysis of a low-speed high-torque hydrostatic transmission unit

    Författare :Håkan Olsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : This thesis concerns a study of the performance of an industrial low-speed high-torque hydrostatic drive system. This type of hydrostatic transmission is commonly used in continuous operation in a wide range of heavy-duty drive applications. In many applications the transmissions have to compete with e.g. LÄS MER
