  2. 1. Deep Learning for Active Fire Detection Using Multi-Source Satellite Image Time Series

    Author : Yu Zhao; Yifang Ban; Andrea Nascetti; Josephine Sullivan; Cartalis Constantinos; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wildfire; Remote Sensing; Active Fire Detection; GOES-R ABI; Suomi-NPP VIIRS; Image Segmentation; Deep Learning; Gated Recurrent Units GRU ; Transformer.; Vilda Bränder; Fjärranalys; Aktiv Branddetektering; GOES- R ABI; Suomi-NPP VIIRS; Bildsegmentering; Djupinlärning; Gated Recurrent Units GRU ; Transformer; Geoinformatik; Geoinformatics;

    Abstract : In recent years, climate change and human activities have caused increas- ing numbers of wildfires. Earth observation data with various spatial and temporal resolutions have shown great potential in detecting and monitoring wildfires. READ MORE

  4. 2. Embedded Measurement Systems

    Author : Lars Bengtsson; Göteborgs universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microcontroller; measurement system; direct sensor-to-controller; time-to-digital converter; phase detector; lock-in amplifier;

    Abstract : The subject of Embedded Measurement Systems (EMS) is the merging of embedded systems and electrical measurement systems. This indicates that EMSs are hardware-software systems dedicated to measuring one or a few physical quantities. READ MORE

  5. 3. Advancing concurrent system verification : Type based approach and tools

    Author : Ramunas Gutkovas; Johannes Borgström; Björn Victor; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Science;

    Abstract : Concurrent systems, i.e., systems of parallel processes, are nearly ubiquitous and verifying the correctness of such systems is becoming an important subject. Many formalisms were invented for such purpose, however, new types of systems are introduced and there is a need for handling larger systems. READ MORE

  6. 4. Helping robots help us : Using prior information for localization, navigation, and human-robot interaction

    Author : Malcolm Mielle; Martin Magnusson; Achim Lilienthal; Erik Schaffernicht; Marjorie Skubic; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; graph-based SLAM; prior map; sketch map; emergency map; map matching; graph matching; segmentation; search and rescue;

    Abstract : Maps are often used to provide information and guide people. Emergency maps or floor plans are often displayed on walls and sketch maps can easily be drawn to give directions. However, robots typically assume that no knowledge of the environment is available before exploration even though making use of prior maps could enhance robotic mapping. READ MORE

  7. 5. Fibre Optic Magnetic Field Sensors Utilizing Iron Garnet Materials

    Author : Hans Sohlström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; yig; iron garnets; rare earth garnets; magneto-opics; optical waveguide; fibre optical sensors; magnetic field measurement; current measurement;

    Abstract : This thesis deals with the subject of fibre optic magnetic field sensors utilizing iron garnet materials. Such materials exhibit a large Faraday rotation which make them advantageous for application in compact mag­netic field sensors. READ MORE
