1. 6. System Identification of a Fixed-Wing UAV Using a Prediction Error Method

   Master-uppsats, Linköpings universitet/Reglerteknik

   Författare :Trulsa Eriksson; [2023]
   Nyckelord :System identification; Fixed-wing UAV; Modelling; Parameter estimation;

   Sammanfattning : Unmanned aerial vehicles (UAVs) is a rapidly expanding area of research due to their versatile usage, such as inspection of places inaccessible to humans and surveillance missions. This creates a demand for a reliable model that can accurately describe the dynamics of the system in order to improve the performance of the vehicle.

3. 7. Implementation of Flight Mechanical Evaluation Criteria in an Aircraft Conceptual Design Tool with focus on Longitudinal Motions

   Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

   Författare :Argyro Giota; Aleksandra Roszkowska; [2023]
   Nyckelord :flight mechanics; Pacelab APD 8.1; aerodynamic derivatives; equations of motion; B747; stability and control; longitudinal dynamics; phugoid mode; short period mode; DATCOM ; OpenVSP;

   Sammanfattning : This report focuses on the utilisation of flight mechanics in the context of aircraftconceptual design to assess stability, control, and motion characteristics. The pri-mary objective is to acquire the equations of motion and implement longitudinalstability and control criteria using Pacelab Aircraft Preliminary Design 8. LÄS MER

4. 8. Characterisation of the LYCCA Double-Sided Silicon Strip Detectors

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

   Författare :Marwan Mohamed; [2023]
   Nyckelord :DSSD LYCCA HISPEC FAIR Characterisation; Physics and Astronomy;

   Sammanfattning : The goal of this thesis work is to describe the methods used and perform comprehensive testing of the Double-Sided Silicon-Strip Detectors (DSSD) prior to their implementation in the Lund-York-Cologne CAlorimeter (LYCCA) detector. In the framework of this project, the DSSD characterisation was carried out to ensure specification compliance prior to their "in-kind contribution" delivery to the HISPEC experiment at the NUSTAR collaboration.

5. 9. The Stern-Gerlach Spectrometer for Charged Particles : A step towards an alternative method for measuring spin

   Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Författare :Samuel Eriksson; [2023]
   Nyckelord :Stern-Gerlach; Stern; Gerlach; spin; time-of-flight; time of flight; magnetic moment; spectrometer; Physics and Astronomy;

   Sammanfattning : The purpose of this project is to investigate the performance of a spectrometer capable of measuring both momentum and spin of particles. More specifically, we investigated what parameters are required in order to separate particles with opposite spins at least 1 mm. LÄS MER

7. 10. Effects of reconstruction parameters on the image quality and quantification of PET images from PET/MRI and PET/CT systems

   Master-uppsats,

   Författare :Ali Amena Hussain; [2022-03-09]
   Nyckelord :Medical physics; PET CT; PET MRI; OSEM; BPL; NEMA IQ; positron emission tomography; magnetic resonance imaging; computed tomography; ordered Subset Expectation Maximization; The Bayesian Penalized Likelihood;

   Sammanfattning : Aim: To study how reconstruction parameters affect the positron emission tomography (PET) image quality and quantitative results for the different lesion to background radioactivity ratios in three different PET systems. Introduction: Multimodality imaging that combines magnetic resonance imaging (MRI) or computed tomography (CT) with a PET system can produce medical images containing both functional and anatomical information.
