1. 16. Detection of Myocardial Ischemia using Real-Time Myocardial Contrast Echocardiography

   Författare :Petri Gudmundsson; Malmö högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardial contrast echocardiography; MCE; stress echocardiography; adenosine; perfusion; real-time; visual; quantative; wall motion; power modulation; bedside; SPECT; coronary insufficiency;

   Sammanfattning : Diagnostisering av syrebrist i hjärtmuskeln med hjälp av kontrastförstärkt ultraljudsundersökning av hjärtmuskelns genomblödning. Ultraljudsundersökning av hjärtat (ekokardiografi) används mycket inom hjärtsjukvården idag, oftast för att utreda hjärtats och hjärtklaffarnas anatomi och funktion. LÄS MER

3. 17. Intermezzon i medieundervisningen. Gymnasieelevers visuella röster och subjektspositioneringar

   Författare :Annika Hellman; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; media education; pupils´ perspective; video diary; visual methodology; subject position; nomadic subjects; visual culture; materiality; rhizom; affect; learning process; upper secondary school;

   Sammanfattning : The starting point of this licentiate thesis is the attempt to make pupils´ perspective on school in general, and media education in particular available and visible. This is done by using a visual research strategy of video diaries, a cumulative method that draws upon students’ knowledge of video diaries from popular culture such as TV-shows. LÄS MER

4. 18. Real-Time Visual Analytics Interfaces to Strengthen Human-Automation Collaboration

   Författare :Elmira Zohrevandi; Jonas Lundberg; Carl Westin; Katerina Vrotsou; Paul Rosenthal; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Abstraction hierarchy; Angular timeline visualization; Air traffic complexity; Air traffic control; Air traffic controller; Conflict detection and resolution; Ecological interface design; Focus context visualization; Human-automation collaboration; Human–computer interaction; Information visualization; Interaction; Rate of climb or descent; Research through design; Safety-critical systems; Visual analytics; Visualization; Visualization design and evaluation methods; Work domain analysis;

   Sammanfattning : Automation in today’s world supports human operators to accomplish several tasks in limited time. With more advanced automation and autonomous systems, the hu-mans’ role is shifting from hands-on operational tasks to supervisory tasks. LÄS MER

5. 19. Feedback Control and Sensor Fusion of Vision and Force

   Författare :Tomas Olsson; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor based robot control; Visual tracking; visual servoing; resource optimization; Kalman filter;

   Sammanfattning : This thesis deals with feedback control using two different sensor types, force sensors and cameras. In many tasks robotics compliance is required in order to avoid damage to the workpiece. Force and vision are the most useful sensing capabilities for a robot system operating in an unknown or uncalibrated environment. LÄS MER

7. 20. Neural limits of visual resolution

   Författare :Zoran Popovic; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cell separation; cortical magnification; detection; estimated receptive field; high-pass filtered optotypes; nyquist limit; psychophysics; resolution; ganglion cells;

   Sammanfattning : Aims: The aim of this thesis was to formulate a model of retinal neural circuitry in humans based on morphological estimates of retinal cone and ganglion cell populations, to compare results based on this model to psychophysical measurements of visual resolution and identify the retinal neural factors that limit visual resolution.Materials & Methods: Total displacement of central ganglion cells from foveal cones was obtained by estimating the length of fibers of Henle in four human retinas along the nasal or vertical hemi-meridians.
