  1. 1. Statistical analysis of metagenomic data

    Författare :Viktor Jonsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Metagenomics; Statistical methods; Hierarchical Bayesian models; Statistical power; False discovery rate; Environmental genomics; Generalized linear models; Count data;

    Sammanfattning : Metagenomics is the study of microbial communities on the genome level by direct sequencing of environmental and clinical samples. Recently developed DNA sequencing technologies have made metagenomics widely applicable and the field is growing rapidly. LÄS MER

  2. 2. Quantitative vulnerability analysis of electric power networks

    Författare :Åke J. Holmgren; Torbjörn Thedéen; Lars-Göran Mattsson; Terje Aven; KTH; []
    Nyckelord :Safety Analysis; vulnerability; homeland security; risk analysis; network; electric power system; blackout; power law; statistical analysis; graph theory; branching process; game theory; Säkerhetsanalys; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Disturbances in the supply of electric power can have serious implications for everyday life as well as for national (homeland) security. A power outage can be initiated by natural disasters, adverse weather, technical failures, human errors, sabotage, terrorism, and acts of war. LÄS MER

  3. 3. Live Single Cell Imaging and Analysis Using Microfluidic Devices

    Författare :Mohammad Ali Khorshidi; Helene Andersson-Svahn; Håkan Jönsson; Carolina Wählby; Johan Elf; KTH; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Single cell analysis; time-lapse fluorescence imaging; automated image analysis; microwell; droplet microfluidics; NK cells; single cell tracking; migration behavior analysis; cell-cell interaction; optical microscopy; image analysis; image processing; microfluidics; immune cells; tracking; counting; morphology analysis;

    Sammanfattning : Today many cell biological techniques study large cell populations where an average estimate of individual cells’ behavior is observed. On the other hand, single cell analysis is required for studying functional heterogeneities between cells within populations. LÄS MER

  4. 4. New Perspectives on Analysis and Design of High-Speed Craft with Respect to Slamming

    Författare :Mikael Razola; Anders Rosén; Ermina Begovic; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Slamming; high-speed craft; finite-element analysis; design methods; experimental analysis; numerical simulations; design loads; statistical analysis; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : High-speed craft are in high demand in the maritime industry, for example, in maintenance operations for offshore structures, for search and rescue, for patrolling operations, or as leisure craft to deliver speed and excitement. Design and operation of high-speed craft are often governed by the hydrodynamic phenomena of slamming, which occur when the craft impact the wave surface. LÄS MER

  5. 5. Mobile Satellite Broadcast and Multichannel Communications : analysis and design

    Författare :Cristoff Martin; Björn Ottersten; Jack Winters; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; communications; satellite broadcast; mobile; MIMO; asymptotic analysis; spatial multiplexing; Signalbehandling; Signal processing; Signalbehandling;

    Sammanfattning : In this thesis, analytical analysis and design techniques for wireless communications with diversity are studied. The impact of impairments such as correlated fading is analyzed using statistical models. Countermeasures designed to overcome, or even exploit, such effects are proposed and examined. LÄS MER
