  2. 1. Studies on Retinal Circulation in Experimental Animals, Healthy Human Eyes and Eyes with Diabetic Retinopathy

    Author : Lidija Tomić; Albert Alm; Einar Stefánsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Retinal Circulation; Labelled Microsphere Technique; Monkeys; Blue Field Simulation; Macular Leukocyte Velocity; Fluorescein Angiogram; Mean Transit Time; Impulse-Response Technique; Arterio-Venous Passage Time; Vessel Diameter; Oxygen; Carbin Dioxide; Diabetes Retinopathy; Ophtalmology; Oftalmologi;

    Abstract : The retina is a highly metabolically active tissue with large demands on the supply of nutrients. Disorders affecting the retina often include some vasculopathy with an impact on retinal circulation. READ MORE

  4. 2. Image Processing Architectures for Binary Morphology and Labeling

    Author : Hugo Hedberg; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; labeling; binary image processing; morphology; Hardware architectures; real-time;

    Abstract : Conventional surveillance systems are omnipresent and most are still based on analog techniques. Migrating to the digital domain grants access to the world of digital image processing enabling automation of such systems, which means extracting information from the image stream without human interaction.

  5. 3. Clinical Studies on Dark Adaptation: with Particular Reference to Carotid Artery Disease

    Author : Ulf Havelius; Oftalmologi (Malmö); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; polycythemia; photoreceptors; phlebotomy; ocular blood flow; headache; dilation lag; dark adaptometry; dark adaptation; color Doppler imaging; carotid artery stenosis; carotid artery disease; carotid endarterectomy; pupil; pupillometry; retinal blood flow; Ophtalmology; Oftalmologi;

    Abstract : Purpose: To study dark adaptation in patients with symptomatic carotid artery disease or polycythemia before and after treatment. This necessitated determinations of pupillary changes as such may influence the findings. To determine whether changes in the retinal blood flow in light and darkness occur in healthy humans.

  6. 4. Observing and influencing preferences in real time. Gaze, morality and dynamic decision-making

    Author : Philip Pärnamets; Kognitionsvetenskap; []
    Keywords : HUMANIORA; HUMANITIES; eye gaze; morality; decision-making; preference formation; embodied cognition;

    Abstract : Preference formation and choice are dynamic cognitive processes arising from interactions between decision-makers and their immediate choice environment. This thesis examines how preferences and decisions are played out in visual attention, captured by eye-movements, as well as in group contexts. READ MORE

  7. 5. Spectral and Temporal Studies of Gamma-Ray Bursts

    Author : Luis Borgonovo; Claes-Ingvar Björnsson; Jerry Fishman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy and astrophysics; Astronomi och astrofysik; Astronomy; astronomi;

    Abstract : Gamma-ray bursts (GRBs) are sporadic flashes of light observed primarily in the gamma-ray band. Being the brightest explosions in the Universe since its birth, they are at present also the furthest astronomical sources detected. READ MORE
