  1. 11. Learning of Definiteness by Belarusian Students of Swedish as a Foreign Language : Inlärning av bestämdhet hos svenskstuderande i Belarus

    Författare :Anders Agebjörn; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; second-language acquisition; third-language acquisition; Russian; English; Swedish; definiteness; noun phrase; implicit and explicit knowledge; cross-linguistic influence; language-learning aptitude; complexity; input frequency;

    Sammanfattning : Through a series of studies, this thesis investigates the learning of definiteness in Russian-speaking students of Swedish. A communicative, oral-production task elicited modified and non-modified noun phrases in indefinite and definite contexts. LÄS MER

  3. 12. Temporal dynamics of brain plasticity : characterizing brain structural changes during skill acquisition

    Författare :Tomás Mediavilla; Daniel Marcellino; Alexandra Badea; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Motor learning; brain plasticity; structural plasticity; magnetic resonance imaging; voxel-based morphometry; tractography; connectivity; motor cortex; posterior parietal cortex; cerebellum; vesicular glutamate transporter;

    Sammanfattning : Traditionally, structural plasticity in the human brain has been considered to follow a linear or asymptotic increase over the course of training. However, recent studies using structural MRI revealed transient increases in grey matter volume (GMV) with learning. LÄS MER

  4. 13. On the Metric-based Approach to Supervised Concept Learning

    Författare :Niklas Lavesson; Sweden Karlskrona Blekinge Institute of Technology School of Engineering Department of Systems and Software Engineering; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; classifier evaluation; supervised learning; metric; criteria;

    Sammanfattning : A classifier is a piece of software that is able to categorize objects for which the class is unknown. The task of automatically generating classifiers by generalizing from examples is an important problem in many practical applications. This problem is often referred to as supervised concept learning, and has been shown to be relevant in e.g. LÄS MER

  5. 14. Deep Learning for Wildfire Progression Monitoring Using SAR and Optical Satellite Image Time Series

    Författare :Puzhao Zhang; Yifang Ban; Lorenzo Burzzone; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Remote Sensing; Deep Learning; Wildfire; Burned Area Mapping; Synthetic Aperture Radar; Change Detection; Segmentation; Optical and Radar Image Analysis; Sentinel-1; Sentinel-2; fjärranalys; djup inlärning; skogsbrand; kartläggning av brända områden; Synthetic Aperture Radar; upptäckt av förändringar; segmentering; analys av optiska och radarbilder; Sentinel-1; Sentinel-2; Geoinformatik; Geoinformatics;

    Sammanfattning : Wildfires have coexisted with human societies for more than 350 million years, always playing an important role in affecting the Earth's surface and climate. Across the globe, wildfires are becoming larger, more frequent, and longer-duration, and tend to be more destructive both in lives lost and economic costs, because of climate change and human activities.

  7. 15. Motorik, koncentrationsförmåga och skolprestationer : en interventionsstudie i skolår 1-3

    Författare :Ingegerd Ericsson; Utbildningsvetenskap; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Physical training; physical education; motor training; Cognition; motor skill observations; motorial learning; sport; Idrott; gymnastik; motorisk inlärning; academic achievements;

    Sammanfattning : The aim of this thesis is to study effects of an extension of physical education/activity and motor training on motor skills, attention and cognition during a period of three years. Another aim is to develop a test, MUGI observationsschema, which could be useful in charting motor skills of school pupils. LÄS MER
