1. 1. Server-side factor graph optimization for on-manifold pre-integration in IoT sensors

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Samuel Gradén; [2023]
   Keywords : Edge computing; IoT; optimization; tracking; drone;

   Abstract : State and specifically location estimation is a core concept in automation and is a well-researched field. One such estimation technique is Moving Horizon Estimation (MHE). In this thesis, the MHE variant single-shooting estimation will estimate the location and velocity of a moving object. READ MORE

3. 2. Improving Objectivity and Reliability of Observational Risk Assessment Tools by using Technical Instruments

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Cephas Charsmar-Etor; [2023]
   Keywords : Direct measurement instruments; Observational instruments; Body segments and postures; Inertial measurement unit; Wearable sensors;

   Abstract : Ergonomic assessments to determine risks of work-related musculoskeletal disorders as well as to compare designs of work-tasks and workstations, are imperative for high sustainability and productivity in any given industry. Hence, assessment tools that can objectively and reliably capture postures, joint angles and muscle activities play very important role in properly determining risks relating to work and various tasks.

4. 3. Arbitrary motion Synthetic Aperture Radar

   University essay from Lunds universitet/Matematisk statistik

   Author : Filip Alberius; Erik Rolander; [2023]
   Keywords : 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;

   Abstract : 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. READ MORE

5. 4. Airspeed estimation of aircraft using two different models and nonlinear observers

   University essay from Linköpings universitet/Fordonssystem

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

   Abstract : 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. READ MORE

6. 5. Linear Position Tracking for Controlling a Robotic Arm Using Inertial Sensors : Development of a Robotic Arm and an Inertial Sensor-Based Tracking System

   University essay from KTH/Skolan för industriell teknik och management (ITM)
