  1. 11. Towards a Digital Twin for Individualized Manufacturing of Welded Aerospace Structures

    Författare :Hugo Hultman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; digital twin; non-nominal welding simulation; geometry assurance;

    Sammanfattning : The aerospace industry is constantly striving towards lower fuel consumption while maintaining a high standard with regards to safety and reliability. These increasing demands require the development of new methods and strategies for efficient and precise manufacturing processes. LÄS MER

  3. 12. Localization, supersymmetric gauge theories and toric geometry

    Författare :Jacob Winding; Maxim Zabzine; Sara Pasquetti; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supersymmetry; gauge theory; localization; toric geometry; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : Gauge theories is one of the most pervasive and important subject of modern theoretical physics, and there are still many things about them we do not understand. In particular dealing with strongly coupled theories where normal perturbative techniques do not apply is a fundamental open problem. LÄS MER

  4. 13. Tensionless Strings and Supersymmetric Sigma Models : Aspects of the Target Space Geometry

    Författare :Andreas Bredthauer; Ulf G. Lindström; Bengt E.W. Nilsson; Uppsala universitet; []
    Nyckelord :Theoretical physics; Theoretical Physics; String Theory; Tensionless Strings; Supergravity Backgrounds; Plane Wave; Supersymmetry; Non-linear Sigma Models; Generalized Complex Geometry; Teoretisk fysik;

    Sammanfattning : In this thesis, two aspects of string theory are discussed, tensionless strings and supersymmetric sigma models.The equivalent to a massless particle in string theory is a tensionless string. Even almost 30 years after it was first mentioned, it is still quite poorly understood. LÄS MER

  5. 14. Geometry Calibration of IceCube : using Photon Timing from Downgoing Muons

    Författare :Matti Jansson; Klas Hultqvist; Stefan Richter; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Sammanfattning : The IceCube Neutrino Observatory at the South Pole has instrumented one cu-bic kilometer of ice by deploying digital optical modules (DOMs) in 86 drillholes, each containing a string of DOMs. So far IceCube has used the locationof the drill tower for the positions of DOMs in the transverse directions (x andy) to the vertical direction (z).

  7. 15. Matematiserande i förskolan : Geometri i multimodal interaktion

    Författare :Gabriella Gejard; Helen Melander; Marie Karlsson; Camilla Björklund; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ethnomethodology conversation analysis; geometry; multimodal interaction; mathematizing; mathematical discourse; preschool activities; preschool children; Pedagogik; Education;

    Sammanfattning : The aim of the dissertation is to contribute with knowledge about mathematizing in preschools, by empirically and analytically examining mathematizing as accomplished in children’s multimodal interactions with each other and their pedagogues in everyday activities. Theoretically and analytically the dissertation is based on an ethnomethodological and conversation analytic perspective (EM/CA) (e. LÄS MER
