    Sammanfattning : This thesis report describes the design and development of an automated rat trap for sewage system. This rat trap has been designed to have a working duration of 2 months or approximately 15749 hits with trap dimensions length 535 mm, width 430 mm and a height range of 931 – 1151 mm with respect to different sewer pipe diameters.

  3. 22. A residual based artificialviscosity method for the stabilizationof the shallow water equations

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Charitini Stavropoulou; [2021]
    Nyckelord :;

    Sammanfattning : The shallow water equations (SWE) are a system of nonlinear hyperbolic partial differential equations, that have been widely used to modelflows in rivers and coastal areas. For many practical purposes, such as flood mitigation and coastal protection, it is extremely important to develop an accurate, efficient, and robust numerical solver. LÄS MER

  4. 23. Towards Vertexing Studies of Heavy Neutral Leptons with the Future Circular Collider at CERN

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

    Författare :Rohini Sengupta; [2021]
    Nyckelord :Particle Physics; CERN; Future Circular Collider; FCC-ee; Heavy Neutral Leptons; Long-lived particles; Displaced signatures;

    Sammanfattning : Heavy Neutral Leptons (HNLs) are the heavier counterparts of the light neutrinos of the Standard Model of particle physics. HNLs can simultaneously solve several of the problems the Standard Model cannot yet resolve, one example being that they provide a candidate for Dark Matter. LÄS MER

  5. 24. Procedural Generation of Modern 3D Cities

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Theodor Angergård; Marcus Ansamaa; Alexander Arvidsson; Jacob Eriksson; Anton Håkansson; Viktor Truvé; [2020-10-29]
    Nyckelord :;

    Sammanfattning : This paper investigates how techniques in Procedural Content Generation (PCG) can be combined with computer graphics theory to generate digital 3D cities suitable for use in media such as games, movies, and advertisements. This research was conducted to discover ways to alleviate the otherwise time-consuming process of manually modeling such cities. LÄS MER

  7. 25. Efficient Calculations of Two-Dimensional Radar Cross-Section Using DGFEM

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

    Författare :Daniel Persson; [2020]
    Nyckelord :numerical methods; DGFEM; discontinuous Galerkin; finite element method;

    Sammanfattning : A two-dimensional discontinuous Galerkin finite element method algorithm in the time domain was developed for calculation of the radar cross-section of an arbitrary object. The algorithm was formed using local nodal basis functions in each element and coupling them via numerical upwind flux. LÄS MER
