  2. 1. A theory of experienced paradoxical tension in co-opetitive alliances

    Author : Tatbeeq Raza-Ullah; Maria Bengtsson; Malin Näsholm; Devi Gnyawali; Marianne Lewis; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; co-opetition; paradox; tension; cognitive difficulty; emotional ambivalence; management; balance; capability; performance; företagsekonomi; Business Studies;

    Abstract : Empirical research shows that co-opetition is a double-edged sword such that it can both help and hurt the achievement of desired performance outcomes. Despite the proliferation of co-opetitive alliances (i.e. READ MORE

  4. 2. Exploring effective descriptions of gauge fields and strings : A Lagrangian approach with insights from color-kinematics duality

    Author : Lucia M. Garozzo; Henrik Johansson; Chris White; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; scattering amplitudes; double copy; gauge theory; string theory; Theoretical Physics; Teoretisk fysik;

    Abstract : The concept of a color-kinematics duality is an important driving force in advancing the modern understanding of scattering amplitudes, in both field theory and string theory. Yet, open questions remain that motivate the need for a deeper understanding of the duality. READ MORE

  5. 3. Inflation and Instabilities of Hyperelastic Membranes

    Author : Amit Patil; Anders Eriksson; Arne Nordmark; Peter Hansbo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membranes; Constrained inflation; Energy release rate; Adhesive contact condition; Limit point; Bifurcation point; Wrinkling; Tension field theory; Pressure induced instability.; Teknisk mekanik; Engineering Mechanics;

    Abstract : The applications of membranes are increasing rapidly in various fields of engineering and science. The geometric, material, force and contact non-linearities complicate their analysis, which increases the demand for computationally efficient methods and interpretation of counter-intuitive behaviours.

  6. 4. Phase-field modeling of surface-energy driven processes

    Author : Klara Asp Grönhagen; John Ågren; Suzana Fries; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-field method; surface energy; solute drag; solid-state sintering; multicomponent multiphase flow; wetting; liquid-phase sintering; spinodal decomposition; CALPHAD; Materials science; Teknisk materialvetenskap;

    Abstract : Surface energy plays a major role in many phenomena that are important in technological and industrial processes, for example in wetting, grain growth and sintering. In this thesis, such surface-energy driven processes are studied by means of the phase-field method. READ MORE

  7. 5. Algorithms and Interaction Potentials: phase density, surface tension and carbon dioxide

    Author : Rasmus Persson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; surface tension; carbon dioxide; density of states; bicalutamide;

    Abstract : This thesis is an amalgamation of articles (Papers I–V) by the author. We present a perturbation algorithm to calculate the phase density, and thus the partition function including its temperature dependence. READ MORE
