    Sammanfattning : The behavior of animals is commonly studied in medicine and biology. There is a large variation in what animals are studied, in experimental paradigms and purpose.However, many studies on animal behavior have at least one thing in common - it typically involves measuring or studying the kinematics of the animal.

  3. 2. Faster data structures and graphics hardware techniques for high performance rendering

    Författare :Per Ganestam; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Computer generated imagery is used in a wide range of disciplines, each with different requirements. As an example, real-time applications such as computer games have completely different restrictions and demands than offline rendering of feature films. A game has to render quickly using only limited resources, yet present visually adequate images. LÄS MER

  4. 3. Water, hyaluronan and surface shape in corneal wound healing after excimer surgery : experimental studies

    Författare :Beat A Weber; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :photorefractive keratectomy; excimer laser; rabbit; cornea; wound healing; microradiography; hyaluronan; planimetry; leukocyte protein marker; haze; regression; surface irregularities; subepithelial deposits; remodeling; epithelial hyperplasia; corticosteroids;

    Sammanfattning : Excimer laser photorefractive keratectomy (PRK) has evolved to a widely performed procedure. The excimer laser corrects refractive ametropias by removing a calculated amount of anterior corneal stroma with great precision and with minimal damage to the adjacent tissues. The correction of myopia up to -5. LÄS MER
