1. 1. On Prism-based Motion Blur and Locking-proof Tetrahedra

   Författare :Mads Rönnow; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; continuous collision detection; locking; GPU; parallel; real time; FEM; motion blur; prism;

   Sammanfattning : Motion blur is an important visual effect in computer graphics for both real-time, interactive, and offline applications. Current methods offer either slow and accurate solutions for offline ray tracing applications, or fast and inaccurate solutions for real-time applications. LÄS MER

3. 2. Cerebellar function during development. Eyeblink conditioning, prism adaptation and interval production in children and adults

   Författare :Karolina Löwgren; foniatri och audiologi Logopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cerebellum; Eyeblink conditioning; Prism adaptation; Finger tapping; Development; Children; Adults; Cerebellar function; Neurodevelopmental disorders; Cognitive disorders;

   Sammanfattning : The focus of this thesis is on cerebellar-dependent sensorimotor tasks during development. The performance in classical delay eyeblink conditioning, prism adaptation, and isochronous serial interval production (finger tapping) was explored in typically developing school-aged children, young adolescents, and adults.

4. 3. A Stacked Prism Lens Concept for Next-Generation Hard X-Ray Telescopes

   Författare :Wujun Mi; Mats Danielsson; Peter Nillius; Ralf K. Heilmann; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; focusing X-ray telescopes; Wolter-I optics; stacked prism lens; focused UV lithography; grayscale e-beam lithography; proximity effect correction; angular resolution; effective collecting area; röntgenteleskop; Wolter-I-optik; staplade prismalinser; fokuserad UV-litografi; elektronstråle-litografi; Fysik; Physics;

   Sammanfattning : Over the past half century, the focusing X-ray telescope has played a very prominent role in X-ray astronomy at the frontier of fundamental physics. The finer angular resolution and increased effective area have enabled more and more exciting discoveries and detailed studies of the high-energy universe, including the cosmic X-ray background (CXB) radiation, black holes in active galactic nuclei (AGN), galaxy clusters, supernova remnants, and so on.

5. 4. Elder abuse through a prism of perceptions : perspectives of potential witnesses

   Författare :Christen Erlingsson; Britt-Inger Saveman; Sharon Carlson; Sture Åström; Fredricka Gilje; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; elder abuse; Delphi technique; focus groups; narrative analysis; risk indicators; ageism; victim blaming; shame; power; compassion; Nursing; Omvårdnad; Omvårdnad;

   Sammanfattning : The overall aim of this thesis was to deepen understanding of elder abuse (EA) by exploring and comparing perceptions held by experts, older persons, representatives of potential support organizations, and family members. Experts’ perspectives (I) were examined through risk indicators and screening questions (a) located in EA literature and (b) selected by an international Delphi panel. LÄS MER

7. 5. A multi-prism lens for hard X-Rays

   Författare :Björn Cederström; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; x-ray; optics; refractive; lens; mammography; synchrotron; Physics; Fysik;

   Sammanfattning : This thesis describes a new type of refractive lens for hardx-rays. It is shown that a linear array of prisms, slightlyinclined with respect to the optical axis, will form a linefocus at a certain distance from the lens. Hence, the namemulti-prism lens. LÄS MER
