  1. 21. Acoustic Noise and Echo Cancelling : Microphone Array Methods and Applications

    Författare :Mattias Dahl; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This Licentiate thesis is divided into three parts corresponding to three different papers. There is one research report, one conference paper and one submitted journal paper. All three parts deal with acoustic echo and/or noise cancelling problems when using adaptive microphone arrays. LÄS MER

  3. 22. Ocean Wave Energy : Underwater Substation System for Wave Energy Converters

    Författare :Magnus Rahm; Mats Leijon; Ted Brekken; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave energy; wave power; wave energy converter; direct-drive; permanent magnet linear generator; point absorber; array; farm; park; offshore; marine; substation; electrical transmission system; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : This thesis deals with a system for operation of directly driven offshore wave energy converters. The work that has been carried out includes laboratory testing of a permanent magnet linear generator, wave energy converter mechanical design and offshore testing, and finally design, implementation, and offshore testing of an underwater collector substation.

  4. 23. Silicon Nanopore Arrays : Fabrication and Applications for DNA Sensing

    Författare :Miao Zhang; Jan Linnros; Meni Wanunu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanopore; array; electrochemical etching; DNA; optics; thermophoresis;

    Sammanfattning : Nanopore biomolecule sensing and sequencing has emerged as a simple but powerful tool for single molecule studies over the past two decades. By elec- trophoretically driving single molecules through a nanometer-sized pore, often sitting in an insulating membrane that separates two buffer solutions, ionic current blockades can be detected to reveal rich information of the molecules, such as DNA length, protein size and conformation, even nucleic acid se- quence.

  5. 24. III-V Nanowire Array Solar Cells: Optical and Electrical Modelling

    Författare :Yang Chen; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Semiconductor solar cell; nanowire array; modelling; Fysicumarkivet A:2018:Chen;

    Sammanfattning : This thesis describes optical and electrical modelling of vertically oriented III-V semiconductor nanowire array solar cells (NWASCs).In the optical studies, three-dimensional electromagnetic modelling was carried out with the scattering matrix method and the finite element method.

  7. 25. Genomic characterization of ETV6/RUNX1-positive acute lymphoblastic leukemia

    Författare :Henrik Lilljebjörn; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SNP array; array CGH; ETV6 RUNX1-positive ALL; childhood ALL; exome sequencing;

    Sammanfattning : The t(12;21) translocation generates the ETV6/RUNX1 fusion gene, present in 25% of childhood acute lymphoblastic leukemia. This fusion gene is important for leukemia development but is not sufficient for leukemia to arise. LÄS MER
