1. 1. Beyond Traditional Tomography: X-ray Multi-projection Imaging for Additive Manufacturing

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

   Author : Maria Esther Vilar Alvarez; [2023]
   Keywords : X-ray tomography; X-ray multiprojection-imaging; deep learning; additive manufacturing; synchrotron radiation; Physics and Astronomy;

   Abstract : The main aim of this bachelor thesis is to push the limits of 3D X-ray imaging by studying the minimum number of projections required to retrieve high-quality reconstructions for additive manufacturing processes. This project first focuses on understanding how X-ray tomography works, by reconstructing additive manufacturing data already obtained (from PSI, TOMCAT beamline) using two standard reconstruction algorithms, GRIDREC and SIRT.

3. 2. Exterior ballistics analysis for rocket propelled KE-penetrator - A conceptual simulation study within fluid mechanics and flight mechanics

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Emil Wegberg; [2022]
   Keywords : Exterior ballistics; fluid mechanics; high-speed aerodynamics; CFD; RANS; conceptual design; Ytterballistik; strömningsmekanik; höghastighetsaerodynamik; CFD; RANS; konceptuell design;

   Abstract : This study has investigated the conceptual feasibility of a rocket propelled kinetic energy penetrator (KEP), designed for the handheld recoilless rifle Carl-Gustaf® 84 mm calibre system, from an exterior ballistics perspective. The methodology is based upon evaluating the aerodynamic properties of different conceptual design proposals through CFD-simulations and then performing trajectory analysis to assess their exterior ballistic performance.

4. 3. Developement of a numeric tool for fatigue life evaluation of the regulating mechanism in Kaplan runners

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Emil Treitler; [2022]
   Keywords : Fatigue; Kaplan; Hydropower; Turbine;

   Abstract : Kaplan turbines are a type of hydropower turbine with adjustable runner blades. This allows the turbine to alter its power output while maintaining a relatively high efficiency over a wide range of power levels. But these frequent blade angel adjustments exposes the turbines internal mechanism to wear and the possibility of fatigue failure. READ MORE

5. 4. Investigating RT using two-particle angular correlations in proton-proton collisions

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

   Author : Dilan Chroscik; [2020]
   Keywords : particle physics; proton-proton collisions; two-particle angular correlations; underlying event; relative transverse activity; ALICE; LHC; collective flow; long range correlations; Physics and Astronomy;

   Abstract : The observable, RT , is investigated using two-dimensional (∆η, ∆φ) angular correlations, where ∆η and ∆φ are the differences in pseudorapidity and azimuthal angle respectively, between the trigger and associated tracks. The analysed data consists of reconstructed tracks, from proton-proton collisions at collision energy ps = 13 TeV, taken from the ALICE detector at the LHC. READ MORE

6. 5. LPI waveforms for AESA radar

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : Andreas Sjöberg; [2020]
   Keywords : Radar LPI waveform AESA;

   Abstract : The purpose of low probability of intercept (LPI) radar is, on top of the standard requirements on a radar, to remain undetected by hostile electronic warfare (EW) systems. This can be achieved primarily by reducing the amount of radiated power in any given direction at all times and is done by transmitting longer modulated pulses that can then be compressed digitally in order to retain range resolution.
