  2. 1. Localization using Distance Geometry : Minimal Solvers and Robust Methods for Sensor Network Self-Calibration

    Author : Martin Larsson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; localization; TDOA; TOA; trilateration; multilateration; distance geometry; registration; sensor network self-calibration;

    Abstract : In this thesis, we focus on the problem of estimating receiver and sender node positions given some form of distance measurements between them. This kind of localization problem has several applications, e.g. READ MORE

  4. 2. Numerical Modelling of Dissolved Air Flotation

    Author : Mia Bondelind; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computational Fluid Dynamics CFD ; 2D; multiphase flow; one-phase; 3D; turbulence; Dissolved Air Flotation DAF ;

    Abstract : Dissolved Air Flotation (DAF), a well-established treatment method for water containing e.g. dissolved organic matter and Cryptosporidium, has previously been examined experimentally. However, most measuring techniques still suffer from disturbances from air bubbles and intrusion of the measuring equipment into the flow. READ MORE

  5. 3. Perceptually Motivated Constraints on 3D Visualizations

    Author : Camilla Forsell; Mats Lind; Thomas Porathe; Uppsala universitet; []
    Keywords : Människa-dator-interaktion; Perception; 3D; Human-Computer Interaction; Information visualization; User studies; Människa-dator-interaktion;

    Abstract : This thesis addresses some important characteristics of human visual perception and their implications for three-dimensional (3D) information visualization. The effort can be divided into two parts. First, findings from vision science are explored and validated. READ MORE

  6. 4. Testing and analysis of composites with 3D woven reinforcement

    Author : Tomas Ekermann; Malin Åkermo; Stefan Hallström; Lars Pilgaard Mikkelsen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D weave; finite element; manufacturing; yarn path; weaving; failure criteria; mechanical testing; 3D väv; finita element; tillverkning; trådbanor; vävning; brottkriterier; mekanisk provning; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : Composites with three-dimensional (3D) reinforcement have several benefits, compared to laminated composites. Their through-thickness reinforcement increase the out-of-plane properties significantly and could eliminate problems with delaminations. Also, these composites have proven to have great damage tolerance and energy absorption. READ MORE

  7. 5. 2D and 3D Reflection Seismic Studies over Scandinavian Deformation Zones

    Author : Emil Lundberg; Christopher Juhlin; Alireza Malehmir; Lars Nielsen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Azimuthal binning; Crooked-line geometry; Cross-dip; Fault zone; Hard rock seismics; MTFC; Quick clay; Shear zone; UDZ; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : The study of deformation zones is of great geological interest since these zones can separate rocks with different characteristics. The geometry of these structures with depth is important for interpreting the geological history of an area. READ MORE
