  1. 6. Data analytics and machine learning for railway track degradation: Using Bothnia Line track measurements for maintenance forecasting

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Elie Roudiere; [2024]
    Keywords : Railway; Track geometry; Machine learning; Statistics; Predictive maintenance; Botniabanan; Järnväg; spårgeometri; maskininlärning; statistik; förebyggande underhåll; Botniabanan;

    Abstract : In this paper, a statistical method is developed to improve predictive maintenance on railway track. The problem tackled is being able to predict when the next maintenance event should take place to guarantee a certain track quality class. READ MORE

  3. 7. Rock Wedge Stability Assessment : A Comparative Analysis of Limit Equilibrium and Discrete Element Methods

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

    Author : Vilma Nordh; [2024]
    Keywords : Numerical modelling; wedge stability; 3DEC; UnWedge;

    Abstract : Rock wedge stability is a common concern in underground excavations. Since the wedge stability influences the support design, it is important to use a wedge stability analysis method that can capture factors like excavation geometry, joint parameters and properties, rock mass properties, rock cover, and stress field as accurately as possible.

  4. 8. Increasing the diodicity of ceramic Tesla valves by exploiting the design freedom of additive manufacturing : A study in design optimizations of Tesla valves for ceramic 3D printing

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Udit Sharma; [2024]
    Keywords : additive; manufacturing; Tesla; valve; ceramic; 3D; printing;

    Abstract : The work presented in this thesis was conducted at Uppsala University and at Fraunhofer IKTS, Dresden. The thesis aims to study design optimizations for increasing the diodicity and thereby performance of a Tesla valve, a type of “no moving parts” (NMP) valve, through design freedoms offered by ceramic additive manufacturing.

  5. 9. ACCESS TO URBAN COOL AND GREEN SPACES FOR OLD ADULTS IN GOTHENBURG – A GIS-BASED ANALYSIS OF RADIANT HEAT

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Robert Klein; [2023-01-19]
    Keywords : urban climate; heat stress; mean radiant temperature; SOLWEIG; urban vegetation; urban planning;

    Abstract : Old adults are particularly vulnerable against heat stress. Considering the ageing society and the projected increase of heat events, planning for heat-resilient urban environments for old adults will become increasingly important. READ MORE

  6. 10. Analysis of Mutable Game Environments Built on a Tetrahedral Mesh : Tetras, a Potential Alternative to Voxels

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

    Author : Noah Tell; [2023]
    Keywords : Voxels; Tetrahedron; Tetrahedral Mesh; Tetrahedralization; Tessellation; Mutable Environment; Editable Terrain; Deformable Environment; Boolean Operations; Real-Time; Computer Games; Computational Geometry; Voxlar; Tetrahedror; Tetrahedralisering; Tessellering; Formbar Terräng; Booliska Operationer; Realtid; Datorspel; Beräkningsgeometri;

    Abstract : Historically 3D game environments have almost always been immutable. Mutable environments are a technical challenge that will affect performance. For games of the future to continue approaching realism, mutable environments are an essential step. READ MORE
