  3. 2. Source Language of Lexical Transfer in Multilingual Learners : A Mixed Methods Approach

    Författare :Hannah Neuser; Maria Kuteeva; Philip Shaw; Camilla Bardel; Scott Jarvis; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; multilingualism; third language acquisition; lexical transfer; crosslinguistic influence; modal differences; proficiency; recency; exposure; psychotypology; L2 status; transferability; markedness; lexical organization; activation; lexical access; English; engelska;

    Sammanfattning : The study reported in this thesis investigates the source language of lexical transfer in multilingual learners using a mixed methods approach. Previous research has shown that the source language of crosslinguistic influence can be related to factors such as proficiency, recency/exposure, psychotypology, the L2 status, and item-specific transferability.

  5. 4. Mechanical Characterization of Engineering Materials by Modal Testing

    Författare :Daniel Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material variability; modal testing; non-destructive test methods; damping ratios; timber beams; plastic panels; aluminium panel; elastic constants; concrete curing; wood-based panels; solids; high-strength concrete; anisotropic materials;

    Sammanfattning : This thesis deals with the use of modal testing for establishing elastic constants of engineering materials and for indicating material variability in terms of stiffness and damping properties. The methodology using modal testing techniques, is applied to timber beams, high strength concrete prisms, wood-based panels (oriented strand board and chipboard), an aluminium alloy panel and plastic laminate panels (high-pressure laminate).

    Sammanfattning : Climate change and densification of cities are two major global challenges. Inthe building and construction industry, there are great expectations that tall timberbuildings will constitute one of the most sustainable solutions. First, verticalurban growth is energy and resource-efficient. LÄS MER
