  2. 1. Wave propagation in graded material composites with extraordinary properties

    Author : Brage B. Svendsen; Mariana Dalarsson; Martin Norgren; Astrid Aksnes; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; gradient-index; waveguides; gold nanoparticles; cancer treatment; left-handed media; negative index materials; metamaterials; Electrical Engineering; Elektro- och systemteknik;

    Abstract : I denna avhandling studeras elektromagnetisk vågutbredning i graderade materialkompositer med extraordinära egenskaper. Två sådana materialkompositsystem studeras särskilt, med hjälp av både analytiska och beräkningstekniska elektromagnetiska metoder. READ MORE

  4. 2. Applications of Structural Bioinformatics for the Structural Genomics Era

    Author : Marian Novotny; Gerard Kleywegt; Geoff Barton; Uppsala universitet; []
    Keywords : Bioinformatics; structural bioinformatics; fold comparison; left-handed helix; docking; solvent-accessible surface area; register shift; X-ray crystallography; Bioinformatik;

    Abstract : Structural bioinformatics deals with the analysis, classification and prediction of three-dimensional structures of biomacromolecules. It is becoming increasingly important as the number of structures is growing rapidly. READ MORE

  5. 3. Some studies on metamaterial transmission lines and their applications

    Author : Xin Hu; Sailing He; Ferran Martin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metamaterial; transmission line theory; composite right left-handed transmission line; diplexer; coupler; balun; interdigital capacitor; split ring resonator; Electrical engineering; Elektroteknik;

    Abstract : This thesis focuses mostly on investigating different potential applications of meta-transmission line (TL), particularly composite right/left handed (CRLH) TL, and analyzing some new phenomena and applications of meta-TL, mostly left-handed (LH) TL. Realization principle will also be studied. READ MORE

  6. 4. Automatic measurement of compression wood and spiral grain for the prediction of distortion in sawn wood products

    Author : Jan Nyström; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Abstract : Distortion is one of the major obstacles for effective utilisation of wood, especially in the building process, where wood has lost market shares to other materials largely because of the lack of straightness. Bow and spring are often caused by compression wood, while twist is the cause of spiral grain. READ MORE

  7. 5. Spiral Grain in Norway Spruce

    Author : Harald Säll; Thomas Thörnqvist; Rolf Birkeland; Växjö universitet; []
    Keywords : Spiral grain angle; drying deformation; warp; wood quality; Norway spruce; Picea abies; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING;

    Abstract : Wood is a major construction material that is used in many contexts, and for different purposes. Serious problems may arise, however, when moisture related deformations as twist occur in wood used in different types of building structures, joinery and furniture. READ MORE
