1. 1. Vehicle dynamics modelling of electromagnetic suspensions for MAGLEV applications

   University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

   Author : Léa Chatelais; [2024]
   Keywords : MAGLEV; Dynamics; Requirements; Suspension; Vehicle modeling; MATLAB; MAGLEV; Dynamisk; Fordran; Upphängning; Fordon modell; MATLAB;

   Abstract : MAGnetic LEVitation Guidance System (MAGLEV) technology was commercially introduced relatively recently in the guided transport field. It is based on removing the wheels and rails of classic railway systems and supporting and guiding the train with magnets and magnetic forces instead. READ MORE

3. 2. Pulse Amplitude Reconstruction in the LDMX Hadronic Calorimeter Readout

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

   Author : Aksel Draguanov Mihaylov; [2023]
   Keywords : Physics and Astronomy;

   Abstract : The universe shows signs of containing some invisible matter, known as dark matter. There are many possible constituents for dark matter, one such being light dark matter which would interact with ordinary matter through a new mediator force and have masses in the range of a few MeV to GeV.

4. 3. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses

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

   Author : Isa Clementsson; [2023]
   Keywords : Physics and Astronomy;

   Abstract : Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficiencies as high as a few percent.

5. 4. Constraining the Higgs width in Higgs production associated with a top quark pair

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Benjamin Dahlén; [2023]
   Keywords : Higgs; width; cross section; on-shell; off-shell; invariant mass; Standard model; upper bound; Physics and Astronomy;

   Abstract : In this thesis we study the width of the Higgs boson in the process pp → t ̄t 4l at LO using MadGraph5_aMC@NLO to generate the events. The contributions including the Higgs signal, continuum background and interference were considered in order to calculate the expected number of events in a broad range of four-lepton invariant masses.

6. 5. Trigger-Level Multiple Electron Event Classification with LDMX using Artificial Neural Networks

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Jacob Lindahl; [2023]
   Keywords : LDMX; ANN; CNN; GNN; RNN; DM; Physics and Astronomy;

   Abstract : Artificial neural networks is a powerful tool for classifying and identifying patterns in large amounts of data. One of the possible tasks of these networks is classification of data into categories. READ MORE
