  1. 26. Linking Probability Theory and Quantum Mechanics, and a Novel Formulation of Quantization

    Författare :Fritiof Wallentin; Andrei Khrennikov; Kisil Vladimir; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum mechanics; contextuality; probabilistic interpretation; Born’s rule; frequentist interpretation; unitary representations; classical statistical mechanics; Koopman-von Neumann formulation; hidden-variable model; quantization.; Matematik; Mathematics;

    Sammanfattning : This doctoral thesis in mathematics consists of three articles that explore the probabilistic structure of quantum mechanics and quantization from a novel perspective.The thesis adopts a probabilistic interpretation of quantum mechanics, which views the archetypical quantum experiments of Bell- and double-slit- type as violating the principle of non-contextuality, i.

  2. 27. Nut - The Goddess of Life in Text and Iconography

    Författare :Nils Billing; Saphinaz-Amal Naguib; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Egyptologi; Ancient Egyptian religion; goddess; mother; water; space; ontology; Pyramid Texts; horizon; tree goddess; Egyptologi; Egyptology; Egyptologi; Egyptology; Egyptologi;

    Sammanfattning : This study delineates the basic characteristics of the ancient Egyptian goddess Nut as expressed in funerary texts and iconography. The goddess is treated as conceptual in character (Begriffsgottheit), i.e. as an animate expression for the ideas that the ancient Egyptians associated with the sky: space and water. LÄS MER

  3. 28. Classical molecular dynamics simulations of collision-induced absorption : method development and evaluation

    Författare :Wissam Fakhardji; Magnus Gustafsson; Javier Martin-Torres; Jean-Michel Hartmann; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Physics; Tillämpad fysik;

    Sammanfattning : In this thesis collision-induced absorption (CIA) coefficients are computed using molec-ular dynamics (MD) simulations. Part I is dedicated to the theoretical frame of the method, from the classical theory radiation to the derivation of an absorption coefficient. LÄS MER

  4. 29. On some Numerical Methods and Solution Techniques for Incompressible Flow Problems

    Författare :Xin He; Maya Neytcheva; Zhong-Zhi Bai; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Sammanfattning : The focus of this work is on numerical solution methods for solving the incompressible Navier-Stokes equations, which consist of a set of coupled nonlinear partial differential equations.In general, after linearization and finite element discretization in space, the original nonlinear problem is converted into finding the solutions of a sequence of linear systems of equations.

  5. 30. Shapes of Spacetimes : Collected tales of black holes

    Författare :Emma Jakobsson; Ingemar Bengtsson; Marc Mars; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Sammanfattning : In theory, the existence of black holes is predicted by general relativity. In reality, there is a general consensus that they exist in space; in particular at the center of many galaxies. The theory of black holes has been around for decades, but there are still interesting questions calling for attention. LÄS MER
