  1. 1. Compact Digital Track Maps: Enhancing Train Traveller Information at the Crossing of Accuracy and Availability : A comparative analysis of algorithms for generating compact representations of railway tracks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Adam Andersson; [2023]
    Keywords : Train positioning; Digital track map; Digital map generation; Position measurement; Global navigation satellite system; Cartography; Tågpositionering; Digitala spårkartor; Generering av digitala kartor; Positionsmätning; Satellitnavigation; Kartograf;

    Abstract : Trains are constrained to the railway tracks they operate on. This can be leveraged for absolute train positioning, where a train’s position can be mapped onto a digital track map (DTM). Extensive research has been dedicated to enhancing the accuracy of DTMs. READ MORE

  3. 2. Canoo Link : From City to Nature

    University essay from Umeå universitet/Designhögskolan vid Umeå universitet

    Author : Andreas Berg; [2021]
    Keywords : Electric vehicle; Autonomous driving; Utility; Subscription; Leisure activities; Nature;

    Abstract : People in cities have a need of recreation. Leisure activities are a big part of people’s health and well- being. Many leisure activities are practiced outside in the nature. Today many citizens do not own a car and public transportation fail to meet the peoples need to move out from the city center out into the wild nature. READ MORE

  4. 3. Real-time Terrain Deformation with Isosurface Algorithms

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Olle Nässén; Edvard Leiborn; [2019]
    Keywords : Isosurface; Marching Cubes; Terrain Deformation; OpenGL; Compute Shader;

    Abstract : Background. Being able to modify virtual environments can create immersive experiences for video-game players. Storing data as volumetric scalar fields allows for highly modifiable 3D environments that can be converted into GPU-friendly triangles with isosurface algorithms. READ MORE

  5. 4. Real-time generation of nature from polygonal data

    University essay from Luleå tekniska universitet/Datavetenskap

    Author : Filip Hännestrand; [2018]
    Keywords : polygon triangulation; ear clipping;

    Abstract : Lantmäteriet is developing an application that can show a three-dimensional representation of Sweden based on the data that Lantmäteriet has. The purpose of this application is to be able to crowdsource improvements and changes to the map data that Lantmäteriet has, it will also be able to be used to improve a case's information for easier and faster turnaround at Lantmäteriet.

  6. 5. Finite Element Modelling and Parametric Studies of Semi-Closed Thin-Walled Steel Polygonal Columns - Application on Steel Lattice Towers for Wind Turbines

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Bona Ryan; [2017]
    Keywords : Lattice tower; Thin-walled element; Semi-closed polygonal section; Finite element analysis; Parametric study; Buckling; Python script; Matlab script; Eurocode 3; Factorial design;

    Abstract : The trend of structural engineering in the recent years is toward the use of lighter and moreeconomical structural elements. In steel construction, peculiarly, thin-walled structural elements arebecoming more popular and have a growing importance. READ MORE
