  1. 1. Numerical simulation of acoustic wave propagation with a focus on modeling sediment layers and large domains

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Elias Estensen; [2022]
    Nyckelord :Helmholtz; wave equation; acoustics; ocean acoustics; numerical analysis; computational science; finite differences; summation by parts; sbp; waveholtz; cylindrical coordinates; sediment layers; interface; super-grid; super grid; absorbing layer; Helmholtz; vågekvationen; akustik; undervattensakustik; numerisk analys; beräkningsvetenskap; finita differenser; summation by parts; sbp; cylindriska koordinater; waveholtz; sedimentskikt; interface; super-grid; absorberande lager;

    Sammanfattning : In this report, we study how finite differences can be used to simulate acoustic wave propagation originating from a point source in the ocean using the Helmholtz equation. How to model sediment layers and the vast size of the ocean is studied in particular. LÄS MER

  3. 2. Analysing the quality of PlaneRCNN plane parameters using a structure from motion system

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Fredrik Österberg; [2021]
    Nyckelord :structure from motion; PlaneRCNN; neural network; sfm; computer vision; RANSAC; planes; room reconstruction; Mathematics and Statistics; Technology and Engineering;

    Sammanfattning : This report aims to compare the plane parameters given by the PlaneRCNN network with those created by using a Structure from Motion (SfM) solution on the same data. Several datasets are used, and the results from PlaneRCNN are evaluated by using the camera matrices from the SfM solution and applying these along with scaling and coordinate transformations.

  4. 3. Geo-Enabling Piste Maps Using Anchor Points

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Lou-Lou Pei; [2021]
    Nyckelord :Georeferencing; Positioning; Coordinate Transformations; Piste maps; Geografiska referenspunkter; Positionering; Koordinattransformationer; Pistkartor;

    Sammanfattning : Piste maps have been used as navigational aids by winter sports enthusiasts for decades. These maps are often hand drawn and are designed to be visually pleasing while still providing an overview of the terrain of a ski resort. LÄS MER

  5. 4. Det självorganiserade hyckleriet: En fallstudie om en storskalig agil transformation

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för företagande och ledning

    Författare :Adrian Bjurefalk; Richard Sjöberg; [2018]
    Nyckelord :Large-scale Agile; organizational transformation; self-organizing teams; neo-institutionalism; case study;

    Sammanfattning : Adopting Agile on a large scale has recently gained popularity. Advocates argue that the flexibility that large-scale Agile brings is necessary to keep up with modern market dynamics. Research indicates that adopting Agile in the large is difficult. LÄS MER

  7. 5. Performing Geographic Information System Analyses on Building Information Management Models

    Master-uppsats, KTH/Geodesi och satellitpositionering

    Författare :Jonas Bengtsson; Mikael Grönkvist; [2017]
    Nyckelord :BIM; GIS; 3D modelling; Coordinated visualisation; 3D analyses; IFC; CityGML; BIM; GIS; 3D-modeller; Samredovisning; 3D-analyser; IFC; CityGML;

    Sammanfattning : As the usage of both BIM (Building Information Modelling) and 3D-GIS (Three-Dimensional Geographic Information Systems) has increased within the field of urban development and construction, so has the interest in connecting these two tools.  One possibility of integration is the potential of visualising BIM models together with other spatial data in 3D.
