  1. 16. Geographical expansion rate of a brown bear population in Fennoscandia and the factors explaining the directional variations

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Lisbet Hougaard Baklid; [2022]
    Nyckelord :Geography; GIS; brown bear; expansion rate; Ursus arctos; Fennoscandia; Sweden; barrier; Earth and Environmental Sciences;

    Sammanfattning : The brown bears, Ursus arctos L., in the Scandinavian peninsula were distributed in almost all counties before aimed reduction during the 1700-1900s (Swenson et al. 1995). From 1981-2013 the population increased more than five times (Chapron et al. LÄS MER

  3. 17. FEM Analysis of paperboard packaging

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Wen-Che Li; [2022]
    Nyckelord :;

    Sammanfattning : The work aims to provide a finite element model using Ansys Workbench for realistically simulating paperboard packages. The geometrical properties of a package and the loading conditions were altered to investigate their influence on the box behavior and the applicability of Ansys as the finite element solver for paperboard material.

  4. 18. Wealth and Risk-Taking: A Cross-Country Study of European Households

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Författare :Gustaf Östblom; [2022]
    Nyckelord :Household finance; Risky share; Participation; Cross-country comparison; Eurozone;

    Sammanfattning : This study investigates the relationship between wealth and risk-taking among European households. Using data from 22 European countries, I show that households with more investable wealth are more likely to invest in risky assets and have a higher risky share conditional on participation.

  5. 19. Estimating Believed Knowledge of Portfolio Agents Using Inverse Optimization

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

    Författare :Gustaf Zachrisson; Oscar Wink; [2022]
    Nyckelord :;

    Sammanfattning : In this report, we demonstrate the utility of inverse optimization in convex programming by applying it on estimating financial market beliefs and behaviors of portfolio investors. The inversion of the optimization  utilized the Karush–Kuhn–Tucker optimality conditions specified for the current situation. LÄS MER

  7. 20. Finding Junctions in Spline-based Road Generation

    Kandidat-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

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

    Sammanfattning : 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. LÄS MER
