1. 21. Age-related maculopathy and macular degeneration : New diagnostic and therapeutic procedures

   Författare :Christina Frennesson; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Age-related maculopathy (ARM) may progress into age-related macular degeneration (AMD), which is often disastrous to near vision and reading. Currently used treatment is generally not successful in a long-term perspective. Therefore, searching for an early detection of functional disturbances as well as for prophylactic treatment appears important. LÄS MER

3. 22. Biological effects of alternating magnetic fields with special reference to the visual system

   Författare :Per Lövsund; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : The aims of the present investigation were to contribute to more knowledge of the interaction between extremely low frequency magnetic fields and excitable tissue and to widen the basic understanding of the mechanisms behind these effects. The human visual system and the frog retina were used as model systems. LÄS MER

4. 23. Detection and Classification Multi-sensor Systems : Implementation of IoT and Systematic Design Approaches

   Författare :Damian Dziak; Wlodek Kulesza; Darius Andriukaitis; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Assessment; Behavior Recognition; Classification; Design Methodology; Detection; Indoor Localization; Internet of Things; Multi-Sensor System; Skills Assessment; Outdoor Localization; Wireless Sensor Network; Applied Signal Processing; Tillämpad signalbehandling;

   Sammanfattning : The detection and classification of features or properties, which characterize people, things or even events can be done in reliable way due to the development of new technologies such as Internet of Things (IoT), and also due to advances in Artificial Intelligence (AI) and machine learning algorithms. Interconnection of users with sensors and actuators have become everyday reality and IoT, an advanced notation of a Multi-sensor System, has become an integral part of systems for assessment of people’s habits and skills as well as the evaluation of quality of things or events' performances.

5. 24. Visual dysfunction and ocular signs associated with periventricular leukomalacia in children born preterm

   Författare :Lena Jacobson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :preterm; retinopathy of prematurity; periventricular leukornalacia; magnetic resonance imaging; delayed visual maturation; visual acuity; crowding; visual field; cognitive visual dysfunction; optic disc; cupping; eye movements; nystagmus; strabismus; reading;

   Sammanfattning : The immature visual system is vulnerable to adverse events in infants born preterm. Both retinopathy of prematurity and periventricular leukomalacia may affect visual function and ocular appearance. LÄS MER

7. 25. Uptake, disposition and acute effects of inhaled organic solvents : sex differences and influence of cytochrome P450 2E1 in human volunteers

   Författare :Lena Ernstgård; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The main aim of the present thesis was to study the influence of sex, cytochrome P450 2E1 and chlorzoxazone on the uptake and metabolism of solvents in humans. Sex differences in acute effects of organic solvents were also assessed. LÄS MER
