1. 1. Screening for diabetic retinopathy : aspects of photographic methods

   Författare :Gunvor von Wendt; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Diabetic retinopathy; diabetic maculopathy; screening; retinal photography; photographic fields; grading scale; inter-observer agreement; inter-method agreement; monochromatic photography; retinal neovascularizations; sight-threatening diabetic retinopathy;

   Sammanfattning : Diabetic retinopathy (DRP) is a major cause of acquired blindness and visual impairment among people of working age as well as those aged 65 years or more. About 3-4% of the population has diabetes mellitus, 35-65% of the diabetic patients have some type of DRP and 10-35% have sight-threatening retinopathy. LÄS MER

3. 2. Transient acoustic fields studied by pulsed TV holography

   Författare :Staffan Schedin; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

   Sammanfattning : Many of the acoustic events that reach our ears are produced by impacted and vibrating bodies. Pulsed holographic interferometry is a suitable technique to record transient events, like sound waves in air from an impacted body or the wave propagation in solid objects. LÄS MER

4. 3. Händelsehorisont || Event Horizon. Distribuerad fotografi

   Författare :Cecilia Grönberg; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; analogue photography; digital photography; distributed photography; decentralised strategies; photography; fotografisk gestaltning; publishing; media ecologies; the book as medium; montage; layers; visual historiography; alternative historiography; artistic research; event horizon;

   Sammanfattning : In recent decades, photography as a technology has undergone a series of transformative changes, which have, in turn, entailed different renegotiations of the functions of photography – as image or information, as inscription or transmission. Within the framework of such a radical shift, this dissertation in photography insists on probing into and exploring the persisting effects of analogue photographs within digital ecologies. LÄS MER

5. 4. Reaching for the Stars : Studies in the History of Swedish Stellar and Nebular Astronomy, 1860–1940

   Författare :Gustav Holmberg; Research Policy Institute (RPI); []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; stellar astronomy; history of astronomy; astrophysics; history of modern Swedish science; scientific practice; Astronomy; Astronomi;

   Sammanfattning : This study considers astrophysics, stellar and nebular astronomy in Sweden. Emphasis is on the role of scientific technologies and practice, and the emergence of a modern observational astronomy, supplanting classical astronomy as the most vital field of Swedish astronomy.

7. 5. Actor-Spectator in a Virtual Reality Arts Play

   Författare :Magali Ljungar-Chapelon; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Artistic crossover; Virtual Reality Art; VR-Cube; Immersion; Interactivity; Experience of art; Audience experience; Performing arts;

   Sammanfattning : This doctoral project brings to the fore the specificity of the artistic experience when the Virtual Reality Cube, a medium based on immersive virtual reality technology, is used as artistic virtual space, where the stage and the auditorium blend into one and spectators and actors no longer have distinctive roles. It consists of three integrated parts: a written thesis, a VR artwork and a DVD, which illustrates the text, the production process of the VR work, and which also presents an interpretation of the research results in filmic and photographic form.
