  1. 1. Penumbra oxygen metabolism and acute neuroinflammation in ischemic stroke : MRI and PET imaging of a M2 occlusion model in rat

    Author : Philip Little; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Acute ischemic stroke (AIS) is caused by the sudden occlusion of a major artery of the brain, and results in infarction and severe ischemia within affected brain regions. If ischemic regions are rapidly revascularized, the neurological disability resulting from AIS can be significantly reduced. READ MORE

  2. 2. Local visual feature based localisation and mapping by mobile robots

    Author : Henrik Andreasson; Achim Lilienthal; Jim Little; Örebro universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; mobile robotics; registration; localisation; SLAM; mapping; omnidirectional vision; 3D vision; appearance based; TECHNOLOGY; TEKNIKVETENSKAP; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Abstract : This thesis addresses the problems of registration, localisation and simultaneous localisation and mapping (SLAM), relying particularly on local visual features extracted from camera images. These fundamental problems in mobile robot navigation are tightly coupled. READ MORE

  3. 3. Thermally Induced Fracture Performance of Asphalt Mixtures

    Author : Prabir Kumar Das; Björn Birgisson; Dallas Little; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low temperature cracking; asphalt concrete fracture mechanics; viscoelasticity; non-linear thermal contraction coefficient; atomic force microscopy; wax; wax crystallization; SRA - Transport; SRA - Transport;

    Abstract : A major distress mode in asphalt pavements is low temperature cracking, which results from the contraction and expansion of the asphalt pavement under extreme temperature changes. The potential for low temperature cracking is an interplay between the environment, the road structure and importantly the properties of the asphalt mixture. READ MORE

  4. 4. Low and Medium Level Vision Using Channel Representations

    Author : Per-Erik Forssén; Gösta Granlund; Jim Little; Linköpings universitet; []

    Abstract : This thesis introduces and explores a new type of representation for low and medium level vision operations called channel representation. The channel representation is a more general way to represent information than e.g. as numerical values, since it allows incorporation of uncertainty, and simultaneous representation of several hypotheses.

  5. 5. Semantic Mapping with Mobile Robots

    Author : Andrzej Pronobis; Patric Jensfelt; Jim Little; KTH; []

    Abstract : After decades of unrealistic predictions and expectations, robots have finally escaped from industrial workplaces and made their way into our homes,offices, museums and other public spaces. These service robots are increasingly present in our environments and many believe that it is in the area ofservice and domestic robotics that we will see the largest growth within thenext few years.
