    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; bimodal bilingual acquisition; Swedish Sign Language; spoken Swedish; case study; longitudinal; sociocultural; mediation; interactional; twins; different hearing statuses; cochlear implant; tillägnande av bimodal bilingualitet; tvåspråkighet; svenskt teckenspråk; talad svenska; fallstudie; longitudinell; sociokulturell; mediering; interaktion; tvilling; hörselstatus; cochlea implantat; specialpedagogik; Special Education;

    Sammanfattning : This dissertation based on a case study explores the acquisition and the guidance of Swedish Sign Language and spoken Swedish over a span of seven years. Interactions between a pair of fraternal twins, one deaf and one hearing, and their Deaf[1] family were video-observed within the home setting. LÄS MER

  3. 2. Digital twinning for ports : from characterization to operations’ modelling

    Författare :Robert Klar; Vangelis Angelakis; Anna Fredriksson; Anders Andersson; Niklas Arvidsson; Theo Tryfona; Statens väg- och transportforskningsinstitut; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Digital twins; Ports; Operational efficiency; Collaborative decision-making; Port decarbonization;

    Sammanfattning : Ports are actively pursuing greater operational efficiency to effectively handle the increasing global flow of goods, while striving to improve the energy efficiency of their operations to comply with new environmental regulations. As a result, innovation-leading ports have begun to recognize the potential of digital twins to overview, coordinate and optimize port processes, resulting in energy savings, and reductions of costs and of CO2 emissions.

  4. 3. Smart pavement maintenance and infrastructure operation through digital twins : Case study for Norvik Port, Sweden

    Författare :Julian Dario Rodriguez; Nicole Kringos; Romain Balieu; Plati Christina; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pavement management; digital twins; finite element model pavement; infrastructure maintenance.; Vägunderhåll; Digitala tvillingar; Ändliga elementmodeller för vägar; Infrastrukturförvaltning; Civil and Architectural Engineering; Byggvetenskap; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Sammanfattning : There is an urgent need to make the way in which people and goods move more sustainable. Though pavements are one of the key components of road transportation networks and logistics systems, they are usually overlooked in systemic sustainability analyses. LÄS MER

  5. 4. Stacking fault energy and deformation behaviour of austenitic stainless steels: a joint theoretical-experimental study

    Författare :Dávid Sándor Molnár; Levente Vitos; Göran Engberg; Guocai Chai; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; austenitic stainless steel; deformation properties; stacking fault energy; electron backscatter diffraction; ab initio; Teknisk materialvetenskap; Materials Science and Engineering; Steel Forming and Surface Engineering;

    Sammanfattning : Austenitiska rostfria stål är främst kända för sin exceptionella korrosionsbeständighet. De har en ytcentrerad kubisk (FCC) struktur som stabiliseras genom att nickel, mangan eller kväve tillsätts till Fe-Cr legeringen. Fe-Cr-Ni-systemet kan utökas ytterligare genom tillsats av andra element såsom Mo, Cu, Ti, C, etc. LÄS MER

  7. 5. Anisotropic Mechanical Behaviours and Thin-wall Effects of Additively Manufactured Austenitic Alloys

    Författare :Cheng-Han Yu; Johan Moverare; Ru Lin Peng; Christian Leinenbach; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser powder bed fusion; Slow strain rate tensile testing; Short-term creep; Low cycle fatigue; Neutrons; Anisotropy; Crystallographic texture; Microstruc-ture; Dislocation structure; Lasersmältning i pulverbädd; Provning med långsam töjningshastighet; korttidskryp; Lågcykelutmattning; Neutroner; Anisotropi; Kristallografisk textur; Mikrostruktur; Dislokationsstruktur;

    Sammanfattning : Additive manufacturing (AM), also known as 3D printing, is a general concept of building a three-dimensional object layer-by-layer. AM breaks through the manufacturing limitations in conventionally subtractive manufacturing, leading to a great design freedom of components with complex geometries. LÄS MER
