  1. 1. Finding Junctions in Spline-based Road Generation

    University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Author : Isak Nyström; Danny Darwiche; [2022]
    Keywords : Bezier; Bezier Subdivision; Convex Hull; De Casteljau; Intersection Detection; Jarvis March; Procedural Geometry; Separating Axis Theorem; Splines; Sutherland-Hodgman;

    Abstract : Splines are a common mixed-initiative technique for road generation. A designer draws the shape of the curve but the mesh can be procedurally generated along the spline. This relationship improves the workflow of building roads in virtual environments and video games without taking away all of the control of the designer. READ MORE

  3. 2. Analys av pressresultat vid pressning av ventilstyrningar i cylinderhuvudet : Analysis of press result when pressing valve guides in the cylinder head

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Elise Fransson; Julia Johansson; [2022]
    Keywords : ;

    Abstract : Examensarbetet har genomförts i samarbete med Aurobay som tillverkar förbränningsmotorer till personbilar. Studien är kopplad till processen där cylinderhuvudet bearbetas och förbereds inför montering. Problematiken som arbetet berörde var pressningen av ventilstyrningar och ventilsäten i cylinderhuvudet.

  4. 3. Methodology for Obtaining S-N Curves using Fatigue Testing and Static FEA

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Filip Anderfelt; David Äse; [2022]
    Keywords : Fatigue; Testing; Fatigue Testing; Test rig; Pneumatic; FEA; Weld; Steel; Fillet Weld; S-N curve;

    Abstract : The use of recommended S-N curves, presented in current literature, to analyse and determine the fatigue life of a part is common practice in, inter alia, the construction industry.However, the recommended S-N curves are generally created for larger components used in mainly the construction industry.

  5. 4. The impact of mechanical characteristics of GDL on the efficiency of a PEM fuel cell

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Klara Olli; [2022]
    Keywords : Fuel Cell; PEM; gas diffusion layer; bipolar plate; intrusion; Technology and Engineering;

    Abstract : When a fuel cell stack is assembled it is compressed to ensure gas tightness, and as a consequence, the Gas Diffusion Layer (GDL) will intrude into the channels of the Bipolar Plate (BPP). In this work, the GDL is studied in compression tests and through intrusion measurements. READ MORE

  6. 5. Scheme Theory & Weak Mordell-Weil for Elliptic Curves Over Number Fields

    University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Carl-Fredrik Lidgren; [2021]
    Keywords : algebraic geometry; schemes; scheme theory; elliptic curves; Mordell-Weil; weak Mordell-Weil; algebraic number theory; arithmetic geometry; number theory; geometry; Mathematics and Statistics;

    Abstract : We provide an introduction to scheme-theoretic algebraic geometry, which studies spaces that are in essence locally solutions to systems of polynomial equations, and prove the weak Mordell-Weil theorem. The weak Mordell-Weil theorem states that for an elliptic curve $E$ over a number field $K$, the quotient $E(K)/mE(K)$ is finite for all $m\geq 2$. READ MORE
