  1. 16. Units of measurement in ecosystems : Design science research on how to communicate and handle units

    University essay from Uppsala universitet/Informationssystem

    Author : Anna Roth; [2023]
    Keywords : Units of measurement; ecosystem; unit checking; annotation burden; design science research;

    Abstract : Units of measurement are needed in many of today’s software programs and datasets for describing physical concepts. Despite this, there are many issues regarding units of measurement in both code and data, such as inconsistent unit annotations, unit types being difficult to annotate and missing built-in unit support in tools and programming languages.

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

    University essay from KTH/Ergonomi

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

    Abstract : 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. READ MORE

  4. 18. Robustness of State-of-the-Art Visual Odometry and SLAM Systems

    University essay from KTH/Tillämpad fysik

    Author : Cassandra Mannila; [2023]
    Keywords : Visual-Inertial Odometry; Visual Odometry; SLAM; Motion blur; ORB-SLAM3; DM-VIO; Robustness;

    Abstract : Visual(-Inertial) Odometry (VIO) and Simultaneous Localization and Mapping (SLAM) are hot topics in Computer Vision today. These technologies have various applications, including robotics, autonomous driving, and virtual reality. They may also be valuable in studying human behavior and navigation through head-mounted visual systems. READ MORE

  5. 19. 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

  6. 20. 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
