1. 6. Thermoplasticity in topology optimization based on finite strain

   University essay from Lunds universitet/Hållfasthetslära

   Author : Anders Engström; [2017]
   Keywords : FEM; topology optimization; finite deformations; thermoplasticity; Technology and Engineering;

   Abstract : A thermoplastic finite strain model is used to model heat generation due to plastic work. Isotropic hardening is used, where the mechanical dissipation acts as heat source in the heat equation. The multiplicative split of the deformation gradient makes it possible to separate plastic and elastic effects. READ MORE

3. 7. Model-Based Output-Only Identication of Coupled Thermoacoustic Modes

   University essay from KTH/MWL Marcus Wallenberg Laboratoriet

   Author : Michael Kristian Pau; [2017]
   Keywords : ;

   Abstract : A model-based output-only method for identifying from time-series data the parameters that determine the dynamics of a stochastically forced thermoacoustic oscillator has previously been implemented in the case of a single standing thermoacoustic mode. This thesis presents an extension of the method in question to two coupled standing modes at the same frequency. READ MORE

4. 8. A supersymmetric, E8 inspired, unification model

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Author : Astrid Ordell; [2016]
   Keywords : Physics and Astronomy;

   Abstract : The thesis treats the construction of a supersymmetric model, inspired by an E8 unfication scenario. Via the introduction of adjoint representation chiral superfields, in combination with the inclusion of a global generation symmetry, the Standard Model fermion candidates are protected from gaining any mass until electroweak symmetry breaking.

5. 9. Source Term Estimation in the Atmospheric Boundary Layer : Using the adjoint of the Reynolds Averaged Scalar Transport equation

   University essay from Umeå universitet/Institutionen för fysik

   Author : Brännvall Tobias; [2015]
   Keywords : CFD; Source; Source term; STE; RANS; k epsilon; Adjoint; Adjoint equation; Reynolds transport equation; transport equation; adjoint of transport equation; Adjoint duality;

   Abstract : This work evaluates whether the branch of Reynolds Averaging in Computational Fluid Dynamics can be used to, based on real field measurements, find the source of the measured gas in question. The method to do this is via the adjoint to the Reynolds Averaged Scalar Transport equation, explained and derived herein. READ MORE

6. 10. Self-adjointness and conservation law of nonlinear dispersive wave equations modelling elasto-plastic flows

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Johan Ermstål; [2012]
   Keywords : Conservation laws; Differential Algebra; Self-adjoint; Wave equation; Symmetry; Fristående kurs;

   Abstract : Two nonlinear dispersive wave equations arising in elasto-plastic flow have been investigated for self-adjointness. For these equations their symmetries are calculated and conservation laws are constructed using two different methods: an old method based on Noether´s Theorem and a new one developed by Prof. Nail Ibragimov.
