  1. 1. (De)coding Modality : The Case of Must, May, Måste and Kan

    Författare :Anna Wärnsby; Engelska; []
    Nyckelord :HUMANIORA; HUMANITIES; English language and literature; semiotics; syntax; modal verbs; modality; English-Swedish Parallel Corpus; epistemic; deontic; dynamic; indeterminacy; Controllability; Transitivity; Data Mining; pragmatics; Engelska språk och litteratur ; semantics; Grammar; Grammatik; semantik; semiotik;

    Sammanfattning : This study investigates the mechanisms of (de)coding modality, focusing on the interpretation of utterances containing the modals must, may, måste, and kan. The main research question posed in this study is what enables the interlocutors to interpret modal expressions so that communicative goals are achieved. LÄS MER

  3. 2. Geometrical and dimensional Measurement Planning : - a systematic and holistic approach

    Författare :Richard Lindqvist; Lars Mattsson; Martin Helgoson; KTH; []
    Nyckelord :Geometrical; dimensional; measurement planning; controllability; GMCP; quality assurance matrix and methodology; QAM; critical key characteristic;

    Sammanfattning : För att försäkra sig om den slutliga kvaliteten på maskinbearbetade komponenter måste tillverkande företag mäta och verifiera de geometriska och dimensionella egenskaperna på komponenter innan dem skickas vidare nedströms till den mer värdeskapande monteringen. Det är idag vanligt att den geometriska och dimensionella mätningen och verifieringen uppstår varje gång då en maskin ställs om, när man startar om eller startar upp en ny produktionslina eller då en produktionsprocess ändras.

  4. 3. Performance Quantification of Interarea Oscillation Damping Using HVDC

    Författare :Joakim Björk; Karl H. Johansson; Lennart Harnefors; Robin Preece; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVDC transmission control; interarea oscillations; power oscillation damping; small-signal stability; frequency control; controllability; MIMO control; decoupling control; multivariable interaction; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : With the transition towards renewable energy, and the deregulation of the electricity market, generation patterns and grid topology are changing. These changes increase the need for transfer capacity. One limiting factor, which sometimes leads to underutilization of the transmission grid, is interarea oscillations. LÄS MER

  5. 4. Dynamic response reconstruction using passive components

    Författare :Anders Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; substructuring; controllability; experimental methods; model calibration; passive control; response reconstruction; model updating; drive signal identification; Time Waveform Replication;

    Sammanfattning : In many testing applications within the field of structural dynamics, such as noise and vibration harshness, rattle and squeak, or durability testing in the automotive and truck industries, large hydraulic or electromagnetic actuators are used to excite the tested structure. Such actuators are mounted in the laboratory in a fixed configuration referred to here as a test rig. LÄS MER

  7. 5. Vibrational Response Reconstruction and Model Validation

    Författare :Anders Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; error metrics; response reconstruction; controllability; rig test; drive signal identification; inverse problems; model validation; state space; model updating;

    Sammanfattning : In this thesis, laboratory response reconstruction andcomputational model validation is investigated. The former concernsapplications of control theory as the objective is to reproduce acertain loading for a known component, while the latter concernsoptimization of a parameterized model as the objective is to modifya computational model to mimic a certain component's behavior.
