  1. 1. Systematic planning and execution of finite element model updating

    Författare :Joakim Wallin; Costin Pacoste; Raid Karoumi; Mario Plos; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamics; finite element model updating; bridge; objective function; updating parameter; mode pairing; dynamik; finita element modelluppdatering; bro; målfunktion; uppdateringsparameter; matchning av moder; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : In design of bridges and for estimation of dynamic properties and load carrying capacity Finite Element Method (FEM) is often used as a tool. The physical quantities used in the Finite Element (FE) model are often connected to varying degrees of uncertainty. LÄS MER

  2. 2. Development of Analytical Methods for Measurement of Drugs against Malaria in Plasma and Whole Blood

    Författare :Daniel Blessborn; Högskolan Dalarna; []
    Nyckelord :Malaria Method Development Pyronaridine Atovaquone Proguanil Malarone Amodiaquine;

    Sammanfattning : The aim of this thesis was to develop analytical methods for measuring drugs in blood and/or plasma. Solid phase extraction was used for the enrichment and purification of the drugs from the sample matrix. LÄS MER

  3. 3. Experimental Design and Updating of Finite Element Models

    Författare :Magnus Andersson; Lennart Ljung; Linköpings universitet; []

    Sammanfattning : This thesis deals with two partly related topics: model updating and actuator/sensor placement concerning finite element (FE) models of large, flexible mechanical structures.The importance of accurate dynamical FE models of mechanical structures in, e.g., aviation/aerospace applications are steadily increasing.

  4. 4. Optimization and Fundamental Insights in Full-Duplex Cellular Networks

    Författare :Jose Mairton B. da Silva Jr.; Carlo Fischione; Gabor Fodor; Geoffrey Ye Li; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; full-duplex; optimization; power control; assignment; beamforming; millimeter wave; self-interference; multi-antenna; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The next generations of cellular networks are expected to provide explosive data rate transmissions and very low latencies. To meet such demands, one of the promising wireless transmissions candidates is in-band full-duplex communications, which enable wireless devices to simultaneously transmit and receive on the same frequency channel.

  5. 5. Ordering in Crystalline Short-Chain Polymer Electrolytes

    Författare :Anti Liivat; Joseph Nordgren; Josh Thomas; Daniel Brandell; David Brown; Uppsala universitet; []
    Nyckelord :Atomic and molecular physics; polymer electrolytes; molecular dynamics; ionic conductivity; crystalline ordering; polymer chain length; smectic; nematic; Atom- och molekylfysik;

    Sammanfattning : Polymer electrolytes are the most obvious candidates for safe "all-solid" Li-ion batteries and other electrochemical devices. However, they still have relatively poor ionic conductivities, which limits their wider adoption in commercial applications. LÄS MER
