1. 16. Improving the guidance, navigation and control design of the KNATTE platform

   Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Lars Lundström; [2023]
   Nyckelord :Multisensor Data Fusion; Nonlinear Kalman Filter; Neural Network;

   Sammanfattning : For complex satellite missions that rely on agile and high-precision manoeuvres, the low-friction aspect of the space environment is a critical component in understanding the attitude control dynamics of the spacecraft. The Kinesthetic Node and Autonomous Table-Top Emulator (KNATTE) is a three-degree-of-freedom frictionless vehicle that serves as the foundation of a multipurpose platform for real-time spacecraft hardware-in-the-loop experiments, and allows emulation of these conditions in two dimensions with the purpose of validating various guidance, navigation, and control algorithms.

3. 17. Validation of a new iPhone application for measurements of wrist velocity during actual work tasks

   Master-uppsats, KTH/Ergonomi

   Författare :Mohammed Abderhman Abaid; [2023]
   Nyckelord :Angular velocity; goniometer; inertial Measurement Unit IMU ; “ErgoHandMeter”; percentile; correlation iii; Vinkelhastighet; goniometer; IMU ; ErgoHandMeter ; percentil; korrelation;

   Sammanfattning : The breakthrough in mobile technology and the development of smartphones, supplied with sensing devices such as Inertial Measurement Units (IMUs), has made it possible to obtain accurate and reliable data on the angular velocity for different objects. The available technical sensors for wrist movements, such as electrogoniometers, are costly, time-consuming, and need a particular computer program to be analyzed. LÄS MER

4. 18. Towards Navigational Aids using Augmented Reality for People with Alzheimer’s Disease in Outdoor Environments : A user study using HoloLens 2 around a University campus

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

   Författare :Léa Prémont; [2023]
   Nyckelord :Augmented reality; Alzheimer’s disease; Navigation; Assistive technology; HoloLens 2; Optical See-Through; Localization; Kalman filter; Hologram; TLX; SUS; Réalité augmentée; Alzheimer; Navigation; Technologie d’assistance; HoloLens 2; Optical See-Through; Localisation; Filtre de Kalman; Hologramme; TLX; SUS; Förstärkt verklighet; Alzheimers sjukdom; Navigering; Tekniska hjälpmedel; HoloLens 2; Optisk genomskinlighet; Lokalisering; Kalman-filter; Hologram; TLX; SUS;

   Sammanfattning : This paper investigates the potential of augmented reality (AR) as a navigational aid for individuals with Alzheimer’s disease (AD), offering innovative solutions to the evolving challenges of AD care. As the disease progresses, patients often require more assistance and may transition to care centers, resulting in reduced independence. LÄS MER

5. 19. Arbitrary motion Synthetic Aperture Radar

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :Filip Alberius; Erik Rolander; [2023]
   Nyckelord :RADAR; SAR; Synthetic Aperture Radar; Pulsed Coherent Radar; PCR; VR; Virtual Reality; IMU; Inertial Measurment Unit; VAA; Virtual Antenna Array; Obstacle detection; Signal Processing; Matched Filter Method.; Technology and Engineering;

   Sammanfattning : Syftet med denna avhandling är att utveckla en ny metod för att producera bilder med syntetisk aperturradar (SAR), med utgångspunkt i scenarier med arbiträr rörelse vad gäller radarsensorn. SAR är en väletablerad metod för att skapa 2- eller 3-dimensionella radarbilder, som traditionellt sett antar att radar-sensorns rörelse är linjär och förutsägbar. LÄS MER

7. 20. Airspeed estimation of aircraft using two different models and nonlinear observers

   Master-uppsats, Linköpings universitet/Fordonssystem

   Författare :Alexander Roser; Anton Thunberg; [2023]
   Nyckelord :sensor fusion; flight mechanics; Kalman filter; extended Kalman filter; unscented Kalman filter; pitot tube; airspeed estimation; simulation;

   Sammanfattning : When operating an aircraft, inaccurate measurements can have devastating consequences. For example, when measuring airspeed using a pitot tube, icing effects and other faults can result in erroneous measurements. LÄS MER
