   Författare :Bernadett Kiss; Internationella miljöinstitutet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Policy learning; technology change; energy efficiency; building;

   Sammanfattning : Experience shows that energy efficiency improvements are the most cost-effective path to meeting global energy challenges. To promote energy efficiency, various policy instruments have been in place since the 1970s. LÄS MER

4. 13. Multispectral Remote Sensing and Deep Learning for Wildfire Detection

   Författare :Xikun Hu; Yifang Ban; Ioannis Gitas; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active fire detection; biome; multi-criteria; Sentinel-2; Landsat-8; burned area mapping; deep learning; semantic segmentation; machine learning.; aktiv branddetektering; biom; multikriterietillvägagångssätt; Sentinel-2; Landsat-8; kartläggning av bränt område; djupinlärning; semantisk segmentering; maskininlärningsmetoderna; Geoinformatik; Geoinformatics;

   Sammanfattning : Remote sensing data has great potential for wildfire detection and monitoring with enhanced spatial resolution and temporal coverage. Earth Observation satellites have been employed to systematically monitor fire activity over large regions in two ways: (i) to detect the location of actively burning spots (during the fire event), and (ii) to map the spatial extent of the burned scars (during or after the event).

5. 14. Digital play in preschools : understandings from educational use and professional learning

   Författare :Leif Marklund; Elza Dunkels; Kenneth Ekström; Åsa Bartholdsson; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; digital play; preschool; digitalisation; tablets; professional learning; professional development; early years; digital competence; literacy; workplace learning; preschool teachers; early childhood education; technology integration; pedagogiskt arbete; educational work;

   Sammanfattning : The purpose of this thesis is to improve knowledge on preschool teachers’ educational use of digital play and their professional learning about it. The thesis is focused on three questions; How can preschool teacher educational use of digital play be understood? How can the professional learning context of preschool teachers using digital play for educational purposes be understood? And, How can preschool teacher knowledge needs concerning educational use of digital play be understood?  The participants were preschool teachers who had started to introduce tablets and digital play in educational practice.

7. 15. Exploring Opportunistic Use of Mobile Devices for Studying in Higher Education

   Författare :Hedin Björn; Stefan Hrastinski; Olle Bälter; Daniel Pargman; Urban Nuldén; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mobile learning; e-learning; mobility; atudying; higher education; Media Technology; Medieteknik;

   Sammanfattning : Students today often feel that they have too much to do and too little time. A common strategy to remedy this is to take advantage of opportunities to use “inter-time”, the time between other activities such as waiting or traveling. LÄS MER
