1. 1. Evaluation of DC Fault Current in Grid Connected Converters in HVDC Stations

   Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

   Författare :Soham SinhaRoy; [2022]
   Nyckelord :Symmetrical monopole; HVDC LCC and VSC; CTL; MMC; Converter reactor; DC smoothing reactor; DC pole-to-pole fault; Peak factor; SCC; SCR; PSCAD EMTDC;

   Sammanfattning : The main circuit equipment in an HVDC station must be rated for continuous operation as well as for stresses during ground faults and other short circuits. The component impedances are thus selected for proper operation during both continuous operation and short circuit events. LÄS MER

3. 2. A Fractional Step Zonal Model and Unstructured Mesh Generation Frame-work for Simulating Cabin Flows

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Sergi Tarroc Gil; [2021]
   Nyckelord :Zonal Model; Thermal Comfort; Fluid Simulation; Aircraft Cabin Design; NURBS; Morphing; Radial Basis Functions; Meshing; Co-located Mesh; Unstructured Mesh; Mesh Quality; Mesh Smoothing; Enlarged Orientation Theorem; Fractional Step Method; Boussinesq; Adam Bashforth; Helmholtz-Hodge Theorem; Rhie and Chow; Difference Schemes; Gradient Evaluation; Differential Heated Cavity; Driven Cavity; Draught Rate;

   Sammanfattning : The simulation of physical systems in the early stages of conceptual designs has shown to be a key factor for adequate decision making and avoiding big and expensive issues downstream in engineering projects. In the case of aircraft cabin design, taking into account the thermal comfort of the passengers as well as the proper air circulation and renovation can make this difference. LÄS MER

4. 3. 3D visualisation of breast reconstruction using Microsoft HoloLens

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

   Författare :Amanda Norberg; Elliot Rask; [2018]
   Nyckelord :AR; Augmented Reality; MR; Mixed Reality; VR; Virtual Reality; Microsoft; Hololens; Breast; Surgery; Modeling; 3D; Human Computer Interaction; Application; Unity; C#;

   Sammanfattning : The purpose of the project is to create a Mixed Reality (MR) application for the 3D visualisation of the result of a breast reconstruction surgery. The application is to be used before surgery to facilitate communication between patient an surgeon about the expected result. LÄS MER

5. 4. Geometric Shape Preservation in Adaptive Refinement of Finite Element Meshes

   Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

   Författare :Ashraful Kadir; [2010]
   Nyckelord :;

   Sammanfattning : This thesis presents a vertex repositioning based boundary smoothing technique so that the finite element mesh, as refined, converges to the geometric shape of the domain. Adaptive mesh refinements based on a posteriori error estimates is already available within FEniCS, a free software for automated solution of differential equations. LÄS MER

7. 5. GPU Accelerated Surface Reconstruction from Particles

   Magister-uppsats, Institutionen för teknik och naturvetenskap; Tekniska högskolan

   Författare :Erik Edespong; [2010]
   Nyckelord :;

   Sammanfattning : Realistic uid eects, such as smoke and water has been pursued by the visual eects industry for a long time. In recent years, particle simulations have gained a lot of popularity for achieving such eects. One problem noted by researchers has been the diculty of generating surfaces from the particles. LÄS MER
