  1. 1. Multistability, Ionic Doping, and Charge Dynamics in Electrosynthesized Polypyrrole, Polymer-Nanoparticle Blend Nonvolatile Memory, and Fixed p-i-n Junction Polymer Light-Emitting Electrochemical Cells

    Författare :Daniel Simon; Sue Carter; Frank Bridges; J Campbell Scott; USA Santa Cruz University of California; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic electronics; polymer; light emission; biomimetics; memory;

    Sammanfattning : A variety of factors make semiconducting polymers a fascinating alternative for both device development and new areas of fundamental research. Among these are solution processability, low cost, flexibility, and the strong dependence of conduction on the presence of charge compensating ions. LÄS MER

  3. 2. Transition to turbulence in the asymptotic suction boundary layer

    Författare :Taras Khapko; Dan Henningson; Philipp Schlatter; Yohann Duguet; Marc Avila; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; boundary layers; instability; laminar-turbulent transition; dynamical systems; edge states; near-wall turbulence; laminarisation;

    Sammanfattning : The focus of this thesis is on the numerical study of subcritical transition to turbulence in the asymptotic suction boundary layer (ASBL). Applying constant homogeneous suction prevents the spatial growth of the boundary layer, granting access to the asymptotic dynamics. LÄS MER

  4. 3. Design and analysis of feedback structures in chemical plants and biochemical systems

    Författare :Henning Schmidt; Elling W. Jacobsen; Frank Allgöwer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signalbehandling; Signal processing; Signalbehandling;

    Sammanfattning : This thesis deals with modelling, analysis, and design of interactions between subsystems in chemical process plants and intracellular biochemical processes. In the first part, the focus is on the selection of decentralized feedback control structures for plants in the chemical process industry, with the aim of achieving a desired performance in the presence of interactions.

  5. 4. Ambiguity at work : lexical blends in an American English web news context

    Författare :Daniel Kjellander; Marlene Johansson Falck; Maria Rosenberg; Suzanne Kemmer; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; lexical blending; data collection methodology; corpus-based investigation; ambiguity; figurativity; cognitive linguistics; teleskopord; datainsamlingsmetod; korpusundersökning; mångtydighet; figurativitet; kognitiv lingvistik; engelska; English; language studies; språkvetenskap; Linguistics; lingvistik;

    Sammanfattning : The present study investigates the word formation process of lexical blending in the context of written US web news between January 2010–March 2018. The study has two interrelated aims. First, it aims to develop a transparent, rigid, and replicable method of data collection. LÄS MER
