  1. 1. Data Mining and Analysis for Characterizing Paper from On-line Multisensor Measurements

    Författare :Marcus Ejnarsson; Adas Gelzinis; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Feature Extraction; Kernel Based Novelty Detection; Kernel CCA; Monitoring; Newsprint; Paper Web; Time-Series Representation; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The objective of this thesis is to develop a multi-resolution tool for screening paper formation variations, aiming to detect abnormalities in various frequency regions ranging from millimeters to several meters. The abnormalities detected in different frequency regions give an indication for the paper maker about specific disturbances in the paper production process. LÄS MER

  3. 2. Mixing and Evaporation at the Cloud Edge and Angular Dynamics of Small Crystals in Viscous Flow

    Författare :Johan Fries; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cloud microphysics; droplet evaporation; reactive flows; Jeffery orbits; shear flow;

    Sammanfattning : How liquid water in atmospheric clouds distributes over droplets of different sizes is important for the initiation of rainfall, and for the optical properties of the atmosphere. Droplet-number densities and droplet-size distributions change rapidly at turbulent cloud edges, where mixing of cloudy and dry air causes cloud dilution and droplet evaporation. LÄS MER

  4. 3. Laser welding of boron steels for light-weight vehicle applications

    Författare :Karl Fahlström; Lars-Erik Svensson; Leif Karlsson; Jens Klaestrup Kristensen; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser welding; boron steel; high strength steels; strength reduction; brittle behavior; crack susceptibility; distortions; light-weight; quality; Manufacturing and materials engineering; Produktions- och materialteknik; Production Technology; Produktionsteknik;

    Sammanfattning : Laser beam welding has gained a significant interest during the last two decades. The suitability of the process for high volume production has the possibility to give a strong advantage compared to several other welding methods. However, it is important to have the process in full control since various quality issues may otherwise occur. LÄS MER

  5. 4. Photon migration in tissue : laser induced fluorescence for cancer diagnostics and influence of optical properties on microvascular Doppler spectroscopy

    Författare :Henrik Nilsson; Othar Svaasand Svansand; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Laser induced flourescence (LIF) is an "optical biopsy" method, based on the selective accumulation of fluorophores in neoplastic tissue. Two recently developed, non-photosensitizing tumor seeking carotenoporphyrins were assessed regarding tumor selectivity, and biodistribution, in experimental animals. LÄS MER

  7. 5. Prerequisites for Efficient Programming of RFID Inlays in Reactive Near Field

    Författare :Markus Frank; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FOM; RNF; RFID; UHF.; Source Impedance Shift; DTLL; Phase compensation;

    Sammanfattning : The electromagnetically isolated programming of unique user IDs, into the transponder memory of UHF RFID inlays, is essential for successful operation in the RFID inventory process. Bar code printers enabled for RFID represent a typical environment of such programming. LÄS MER
