  1. 1. Measurement and Application of Multidirectional Mobilities

    Författare :Michael A. Sanderson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; source signal filtering; mass loading; rotational mobility; rotational inertia loading; multidirectional mechanical mobility; moment mobility; structural intensity; measurement techniques; vibration isolation;

    Sammanfattning : The direct measurement of moment mobility, employing a twin exciter technique, is theoretically and experimentally examined. This is continued by a theoretical and experimental analysis of an improved technique using source signal filtering, for two degrees of freedom, for the measurement of multidirectional mobilities.

  3. 2. Multidirectional Mobilities - Advanced Measurement Techniques and Applications

    Författare :Lars H. Ivarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; R-DOFs; substructuring; measurement techniques; rotational mobility; multidirectional mechanical mobility; hybrid coupling; coupling; moment mobility; impedance coupling; consistency;

    Sammanfattning : Today high noise-and-vibration comfort has become a quality sign of products in sectors such as the automotive industry, aircraft, components, households and manufacturing. Consequently, already in the design phase of products, tools are required to predict the final vibration and noise levels. LÄS MER

  4. 3. Snakes and Ladders : Developmental Aspects of Lexical-Conceptual Relationships in the Multilingual Mental Lexicon

    Författare :Lari-Valtteri Suhonen; Språkinlärning; []
    Nyckelord :HUMANIORA; HUMANITIES; third language acquisition; cross-linguistic influence; mental lexicon; multilingualism; psychotypology; L3; attrition; second language acquisition; SLA; TLA; transfer; concept; cognitive control; working memory; CLI; multidirectional; multilingual mental lexicon; MML; acquisition; learning; translation ambiguity; introspection; longitudinal;

    Sammanfattning : One phenomenon causing issues for language learners in the form of cross-linguistic influence (CLI) is translation ambiguity (Eddington & Tokowicz, 2013). Translation ambiguity refers to a situation where word meanings are different in a speaker’s languages. LÄS MER

  7. 5. Volunteer Muscle Activity in Dynamic Events. Input Data for Human Body Models

    Författare :Jóna Marin Olafsdottir; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; emergency braking; ative human body model; multidirectional perturbations; EMG; occupant kinematics; seatbelt pre-tension; reflex; validation data;

    Sammanfattning : Human body models (HBMs) are virtual human surrogates used to predict kinematic and injury responses during motor vehicle crashes. In recent years, active musculature has been incorporated into HBMs for enhanced biofidelity in simulated emergency scenarios, in particular low-severity crashes and pre-crash situations, where occupant responses are influenced by muscle tension.
