  1. 1. Studies of Dark Showers for Present and Future Colliders

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Author : Nicoline Krogh Hemme; [2022]
    Keywords : high-energy particle physics; dark matter; collider physics; beyond the standard model; Physics and Astronomy;

    Abstract : In this work we explore a strongly-interacting dark sector with a Z’ portal to the Standard Model. We focus on the dark shower phenomenology and their semi-visible jet signatures with a strong emphasis on first principles of the theory. READ MORE

  3. 2. Exploring the Diversity of Exoplanets

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Rebecka Svensson; [2021]
    Keywords : Exoplanets; Super-Earth; Sub-Neptune;

    Abstract : The search for extrasolar planets had been ongoing for many years when Mayorand Queloz discovered 51 Pegasi b in 1995. It was a giant gas planet similar to Jupiter, but with a larger radius and of only half of Jupiter’s mass. Theso called Hot Jupiter was observed to orbit its host star 7 times closer thanMercury is orbiting the Sun. READ MORE

  4. 3. Comparison of spatial partitioning data structures in crowd simulations

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

    Author : Jakob Kratz; Viktor Luthman; [2021]
    Keywords : Radius Search; Spatial Partitioning; Agent- Based Simulation; Boids; Grid; Kd- Tree; Quadtree; Maximum Velocity; Radius Search; Spatial Partitioning; Agent- Based Simulation; Boids; Grid; Kd- Tree; Quadtree; Maximum Velocity;

    Abstract : This report investigates how the construction and query time of multiple spatial partitioning data structures is impacted by spatial distribution of and number of agents in a crowd simulation. In addition a method is investigated for updating the data structures less frequently at the cost of increasing the radius queried, without affecting the correctness of the queries. READ MORE

  5. 4. Evolution and Differentiation of Large Icy Moons

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Piia Tomberg; [2021]
    Keywords : Physics and Astronomy;

    Abstract : Purpose: In preparation of several future missions with the objective to research the large icy moons of the Solar System, it is necessary to have a cohesive understanding of the conditions that might lead to the formation of liquid oceans in these moons. The purpose of this work is to create a numerical model for simulating the temperature evolution of the cores of large icy moons. READ MORE

  6. 5. Tesla Valve for Hydrogen Decompression: Fluid Dynamic Analysis

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Elias Bäckman; Mathilda Willén; [2019]

    Abstract : Människans påverkan på växthuseffekten har under de senaste åren varit en mycket aktuell fråga. Det är många olika faktorer som bidrar till ett negativt avtryck på miljön, där ett stort bidrag kommer från sektorn bilindustri. Majoriteten av dagens bilar drivs på fossila bränslen som genererar skadande utsläpp på miljön. READ MORE
