  1. 11. Accelerator physics studies of the MAX-lab storage rings

    Författare :Magnus Sjöström; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron accelerator; linear optics; storage ring; characterisation; synchrotron radiation; emittance; intrabeam scattering; electron beam profile;

    Sammanfattning : Within research, synchrotron radiation is a highly useful probe for the study of materials, their properties and structures. Currently, no other radiation source allows the combination of high intensity and short wavelengths. LÄS MER

  3. 12. The injured anterior cruciate ligament and neuromuscular rehabilitation

    Författare :Rose Zätterström; Människan i rörelse: hälsa och rehabilitering; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; long-term follow-up; short-term; non-surgical treatment; ACL injury; associated lesions; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Two prospective, short-term and long-term consecutive randomized studies on non-surgical treated patients with an ACL injury were performed. None of the patients were athletes on a professional level. LÄS MER

  4. 13. Morphometric and Landscape Feature Analysis with Artificial Neural Networks and SRTM data : Applications in Humid and Arid Environments

    Författare :Amir Houshang Ehsani; Friedrich Quiel; Wolfgang Wagner; KTH; []
    Nyckelord :Self Organizing Map; Neural Network; Morphometric Feature; Landscape; Yardang; Lut Desert; Potential natural vegetation; geoecosystem; Landform; Landsat ETM ; Morphometric Parameters; SRTM; Resolution; Curvatures; DEM.; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis presents a semi-automatic method to analyze morphometric features and landscape elements based on Self Organizing Map (SOM) as an unsupervised Artificial Neural Network algorithm in two completely different environments: 1) the Man and Biosphere Reserve “Eastern Carpathians” (Central Europe) as a complex mountainous humid area and 2) Lut Desert, Iran, a hyper arid region characterized by repetition of wind-eroded features. In 2003, the National Aeronautics and Space Administration (NASA) released the SRTM/ SIR-C band data with 3 arc seconds (approx. LÄS MER

  5. 14. Effect of high-temperature drying on spruce and larch Shape stability, mechanical properties and mould growth

    Författare :Eva Frühwald; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; twist; shape stability; Norway spruce; mould susceptibility; larch; high-temperature drying; distortion; Technological sciences; Teknik; Material technology; Materiallära; Building construction; materialteknik; heat-treatment; Byggnadsteknik; KSTRWood;

    Sammanfattning : Shape stability, the ability of the wood to retain its shape, is one of the most important parameters when using timber as a building material and for other applications. Generally, timber undergoes changes in dimensions and shape when its moisture content is changed. LÄS MER

  7. 15. Stiffness of reverse channel connections at room and elevated temperatures

    Författare :Tim Heistermann; Darko Beg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : A frame structure exposed to fire undergoes two types of changes due to the resulting temperature fields. The first is the thermal expansion of the structural members and the second is the degradation of the material strength and stiffness as temperature rises. LÄS MER
