1. 11. Vector Symbolic Architectures and their applications : Computing with random vectors in a hyperdimensional space

   Författare :Denis Kleyko; Evgeny Osipov; Mika Laiho; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

   Sammanfattning : The main focus of this thesis lies in a rather narrow subfield of Artificial Intelligence. As any beloved child, it has many names. The most common ones are Vector Symbolic Architectures and Hyperdimensional Computing. LÄS MER

3. 12. Brain processing of experimental muscle pain and its interrelation with proprioception and muscle fatigue : positron emission tomography study

   Författare :Alexander Korotkov; Docent Tomas Graven-Nielsen; Umeå universitet; []
   Nyckelord :Experimental muscle pain; Hypertonic saline; Kinesthesia; Proprioception; Movement; Vibration; Muscle fatigue; Brain; Imaging; Positron emission tomography; Regional cerebral blood flow;

   Sammanfattning : Chronic muscle pain is a significant medical and social problem and better understanding of the pathophysiological mechanisms involved is an important requirement for further development of diagnostics, treatment and rehabilitation methods. Experimental imaging studies have investigated functional neuroanatomy of different pain components. LÄS MER

4. 13. Reanalysis of primate head impact experiments to clarify mild traumatic brain injury kinematics and thresholds

   Författare :Jacobo Antona; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; Brain; finite element; injury criteria;

   Sammanfattning : Fatalities and severe injuries due to road traffic accidents still represent a serious health and economic issue intoday’s society. Brain injuries are the most common severe injuries and these injuries account for more than half ofthe 1.3 million traffic related deaths annually worldwide. LÄS MER

5. 14. Using Virtual Reality for Participatory Design and Brain Injury Rehabilitation

   Författare :Roy Davies; Ergonomi och aerosolteknologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pollution control; Environmental technology; Data- och systemvetenskap; computer technology; Systems engineering; Case Studies; Brain Injury Rehabilitation; Participatory Design; Virtual Reality; Usability; Applications; Miljöteknik; kontroll av utsläpp; Physical medicine; kinesitherapy; revalidation; rehabilitation; Rehabilitering medicinsk och social ;

   Sammanfattning : In this thesis, the usability of Virtual Reality (VR) has been investigated and developed within two applications: participatory design of workplaces and brain injury rehabilitation. In the first application, VR is used in combination with full scale modelling, drama and democratic meetings in an Envisionment Workshop. LÄS MER

7. 15. Brain-derived neurotrophic factor in cerebral ischemia: a quantitative study on surviving and newly formed neurons

   Författare :Elin Gustafsson; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain-derived neurotrophic factor; cerebral ischemia; neuronal survival; neurogenesis; hippocampus; striatum; immunocytochemistry; stereology; neuropsykologi; Neurologi; neurophysiology; neuropsychology; neurofysiologi; Neurology;

   Sammanfattning : This study explores the role of brain-derived neurotrophic factor (BDNF) for neuronal vulnerability and neurogenesis following cerebral ischemia in the rat. Cerebral ischemia results in selective neuronal cell loss in specific brain regions. We here demonstrate the rank order of vulnerability in two regions affected by global forebrain ischemia, i.
