1. 1. Is there a benefit of super spikes in long jump performance?

   Master-uppsats, Gymnastik- och idrottshögskolan, GIH/Institutionen för fysisk aktivitet och hälsa

   Författare :Erik Svensson; [2023]
   Nyckelord :Long jump; long jump performance; AFT; super shoes; super spikes; carbon fiber plate; athletics; track field; jump; biomechanics; sprint; speed; force;

   Sammanfattning : Background and aim The pace of development of distance running shoes has been fast-forward since 2016 when Nike introduced their model Nike Zoom Vaporfly, with an imbedded carbon fiber plate and an advanced newly developed Pebax®-foam. The shoe-development has continued to track events, with the introduction of carbon fiber plate in several shoe-models for running and sprint- events. LÄS MER

3. 2. Magnetic and Dielectric Design of Auxiliary Power Supply for HVDC Applications : A high-frequency transformer with high power transfer capability and high voltage electrical insulation

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

   Författare :Henrik Johansson; [2022]
   Nyckelord :Auxiliary Power Supply; HVDC; Inductive Power Supply; High Voltage Insulation; High-Frequency Transformer; Hjälpkraftsförsörjning; HVDC; Induktiv Kraftförsörjning; Högspänningsisolation; Högfrekvenstransformator;

   Sammanfattning : It is anticipated that massive amounts of energy will be transferred long distances via High-Voltage Direct Current (HVDC) links in the future and the prospect of having meshed HVDC grids is envisioned, for example the European super grid. Such a power system would benefit greatly if HVDC circuit breakers could reliably clear faults within the HVDC network. LÄS MER

4. 3. Numerical simulation of acoustic wave propagation with a focus on modeling sediment layers and large domains

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

   Författare :Elias Estensen; [2022]
   Nyckelord :Helmholtz; wave equation; acoustics; ocean acoustics; numerical analysis; computational science; finite differences; summation by parts; sbp; waveholtz; cylindrical coordinates; sediment layers; interface; super-grid; super grid; absorbing layer; Helmholtz; vågekvationen; akustik; undervattensakustik; numerisk analys; beräkningsvetenskap; finita differenser; summation by parts; sbp; cylindriska koordinater; waveholtz; sedimentskikt; interface; super-grid; absorberande lager;

   Sammanfattning : In this report, we study how finite differences can be used to simulate acoustic wave propagation originating from a point source in the ocean using the Helmholtz equation. How to model sediment layers and the vast size of the ocean is studied in particular. LÄS MER

5. 4. Fast-forward the Sedimentation of Solid Particles in Protoplanetary Disks

   Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Eric Andersson; [2017]
   Nyckelord :protoplanetary disk sedimentation simulation particle-mesh adaptive particles; Physics and Astronomy;

   Sammanfattning : Numerical simulations have become an essential tool for studying particle-gas systems. One such system is the protoplanetary disk consisting of vast number of solid particles interacting with the surrounding gas. LÄS MER

7. 5. The parametrisation of cross sections for Dark Matter particle processes

   Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Conrad Schwanitz; [2017]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : Experiments at particle colliders provide experimental verifications of theories in particle physics, and allow to search for new particles. Computer programs are used to simulate particle collisions. Those so-called event generators can be used to prove theories and compare their results to actual collisions from the colliders. LÄS MER
