1. 1. Tracing Tempera through Time-of-Flight Secondary Ion Mass Spectrometry Analysing samples from four icons from the Nationalmuseum collection

   Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Nina Olivier; [2024-01-30]
   Nyckelord :Icons; tempera; emulsions; analysis methods; ToF-SIMS;

   Sammanfattning : This thesis will analyze samples in form of cross-sections taken from four icons of the Nationalmuseum collection, two Russian, from the 18th and 19th centuries and two Greek, also from the 18th and 19th centuries, using the Time-of-Flight Secondary Ion Mass Technique. The objective is to detect, isolate and, if possible, identify the amino acids and the fatty acids in the protein and lipids used in the tempera, the ground, and the olifa using Time of Flight Secondary Ion Mass Spectrometry.

5. 4. Information requirements for future operators of autonomous drones at airports

   Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :Jonathan Källbäcker; [2023]
   Nyckelord :Autonomous drones; airports; cognitive work analysis; thematic analysis; interface requirements; information requirements.;

   Sammanfattning : To gain an understanding about what information requirements there are for future operators of autonomous drone swarms at airport, this study examined how work at airports is structured today, what staff at airports think about the potential implementation of autonomous drones, and what potential interface components that are necessary to be able to control these drones. Interviews and observations were made at five different airports and air traffic control towers with tower and ground staff. LÄS MER

7. 5. Robust Aircraft Positioning using Signals of Opportunity with Direction of Arrival

   Master-uppsats, Linköpings universitet/Reglerteknik

   Författare :Erik Axelsson; Sebastian Fagerstedt; [2023]
   Nyckelord :Simultaneous localisation and mapping; direction of arrival; signals of opportunity; extended Kalman filter; positioning;

   Sammanfattning : This thesis considers the problem of using signals of opportunity (SOO) with known direction of arrival (DOA) for aircraft positioning. SOO is a collective name for a wide range of signals not intended for navigation but which can be intercepted by the radar warning system on an aircraft. LÄS MER
