  1. 6. Applications of Finite Element Simulation and Mixed Reality in Architecture and Built Environment

    Författare :Carl Lundholm; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; augmented reality; FEniCS; multimesh; CutFEM; multi-objective optimization; mixed reality; HoloLens; virtual reality; view computation; finite element method;

    Sammanfattning : This thesis presents applications in architecture and built environment that are based on the finite element method and mixed reality. The work consists of two main components: two projects presented in three papers. The first project (presented in Paper I) concerns an application in urban design, thus built environment on a larger scale. LÄS MER

  3. 7. Adaptive variational multiscale methods

    Författare :Axel Målqvist; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; finite element method; Galerkin; duality; a posteriori error estimation; adaptivity; variational multiscale method; mixed formulation; multi-physics; oil reservoir simulation; finite element method;

    Sammanfattning : In this thesis we present a new adaptive multiscale method for solving elliptic partial differential equations. The method is based on numerical solution of decoupled local fine scale problems on patches. LÄS MER

  4. 8. Aerodynamic Design and Aeromechanical Analysis of Mixed and Radial Flow Turbines : A study on meanline method, stator tilting endwall design and forced response analysis

    Författare :Yang Gao; Andrew R. Martin; Jens Fridh; Damian Vogt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbomachinery; CFD; aerodynamics; aeromechanics; mixed flow turbine; Energy Technology; Energiteknik;

    Sammanfattning : In this energy transition era, turbocharging is still an important technology for the automotive industry to reduce fuel consumption and lower emissions in its vehicles. This importance can be seen from both conventional fossil-fuel powertrains, and emerging applications, such as increased utilization of biofuels along with hydrogen fuel cells. LÄS MER

  5. 9. Reduction of Substrate Noise in Mixed-Signal Circuits

    Författare :Erik Backenius; Mark Vesterbacka; Kejll O. Jeppson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mixed-signal; Substrate noise; Substrate modeling; Simultaneous switching noise; SSN; Digital; Analog; Clock; Electronics; Elektronik;

    Sammanfattning : In many consumer products, e.g., cellular phones and handheld computers, both digital and analog circuits are required. Nowadays, it is possible to implement a large subsystem or even a complete system, that earlier required several chips, on a single chip. LÄS MER

  7. 10. Contributions to nonlinear mixed-effects modeling

    Författare :Jacob Leander; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nonlinear mixed-effects models; stochastic differential equations; parameter estimation; extended Kalman filter; sensitivity equations; stochastic differential equations;

    Sammanfattning : The topic of this thesis is nonlinear mixed-effects models. A nonlinear mixed-effects model is a hierarchical regression model used to analyze measurements from several individuals simultaneously, which allows sharing of information between similar individuals. LÄS MER
