4. 2. Communication as structuration : Viewing learning through the lens of communication

   Author : Cynthia Jimes; Lowe Hedman; Peder Hård af Segerstad; Bengt-Åke Gustafsson; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Media and communication studies; organizational communication; organizational learning; structure; agency; texts; conversations; structuration; discursive communication theory; sociocultural learning theory; theoretical study; abduction; business processes; Medie- och kommunikationsvetenskap; Media and communication studies; Medie- och kommunikationsvetenskap; Medie- och kommunikationsvetenskap; Media and Communication Studies;

   Abstract : This dissertation is about enlightening the relationship between organizational communication and learning. In doing so, I explore and build upon existing theories that address the relationship from a structuration perspective. Specifically, I turn to discursive communication theory and sociocultural learning theory. READ MORE

5. 3. Enhancing the performance of the Digital Cherenkov Viewing Device : Detecting partial defects in irradiated nuclear fuel assemblies using Cherenkov light

   Author : Erik Branger; Sophie Grape; Christopher Orton; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; DCVD; Nuclear safeguards; Cherenkov light; Nuclear fuel assembly; Partial defect verification; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

   Abstract : The Digital Cherenkov Viewing Device (DCVD) is an instrument used by authority safeguards inspectors to verify irradiated nuclear fuel assemblies in wet storage based on Cherenkov light emission. It is frequently used to verify that parts of an assembly have not been diverted, which is done by comparing the measured Cherenkov light intensity to a predicted one. READ MORE

6. 4. The value of simplicity : image browsing techniques and tests

   Author : Anna Hedman; Karl W. Sandberg; Luleå tekniska universitet; []
   Keywords : ;

   Abstract : Image browsing is involved in many different types of tasks, such as interacting with a desktop and file system, viewing digital photo albums, etc. Different techniques are available for different types of tasks, but results from image browsing tests have been varied. READ MORE

7. 5. Optimal Use of Peripheral Vision

   Author : Karthikeyan Baskaran; Jörgen Gustafsson; Peter Unsbo; Staffan Carius; Michael Crossland; Linnéuniversitetet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; off-axis refractive errors; peripheral aberrations; aberrometers; central visual field loss; preferred retinal locus; eccentric viewing; absolute central scotoma; adaptive optics; eccentric correction.; Optometry; Optometri;

   Abstract : People who lose their central vision have to rely on their peripheral vision for all visual tasks. The ability to resolve fine details in the periphery is reduced due to retinal limitations and the optical aberrations arising from the use of off-axis vision. READ MORE
