2. 1. Low noise frequency combs and their use in broadly tunable lasers and optical coherence tomography

   Author : Connor Skehan; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical frequency comb; optical injection locking; comb noise;

   Abstract : Frequency combs revolutionized the world of laser physics by providing a link between the microwave and optical domains. Such a link allows for precise knowledge of any comb line’s absolute average location, as well as the average spacing between any two comb lines. READ MORE

4. 2. Computational studies on 2D and 3D amorphous solids : Investigation of structure-property relationship

   Author : Emel Gürbüz; Biplab Sanyal; Andreas Larsson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amorphous solids; Metallic glasses; Classical molecular dynamics simulations; Thermal transport; Density functional theory; 2D glasses; Vibrational properties; Magnetism; Optical properties;

   Abstract : Amorphous materials represent a large and diverse family, with many questions still remaining unanswered regarding their structure-property relationship. The structural complexity of these materials poses challenges for simulations in contrast to crystalline materials where density func­tional theory (DFT) can be used easily by exploiting the translation symmetry.

5. 3. Product-service systems: Panacea or myth?

   Author : Oksana Mont; Internationella miljöinstitutet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic systems; economic policy; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik; Production technology; Produktionsteknik; economic theory; econometrics; Economics; communal washing centres.; car sharing; systems for sharing power tools and garden-care equipment; product policy; drivers and barriers for companies; servicising; life cycle thinking; Product-service systems; functional thinking;

   Abstract : Life cycle environmental problems have been addressed by a number of strategies. However, the results are mostly lamentable because solutions are searched for within the same paradigms that give rise to the problems. READ MORE

6. 4. The problem-solving citizen

   Author : Jonas Dahl; Malmö högskola; []
   Keywords : Mathematics education; Problem solving; Equity; Upper secondary school; Curriculum;

   Abstract : The present thesis is made up by three articles and in all of these the mathematics curriculum for upper secondary school in Sweden is analysed. The main focus is the citizen and citizenship and the point of departure is problem solving as a competence. READ MORE

7. 5. Experimental study of the rotating-disk boundary-layer flow

   Author : Shintaro Imayama; Henrik Alfredsson; Rebecca Lingwood; Benoît Pier; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; boundary layer; rotating disk; laminar-turbulent transition; convective instability; absolute instability; secondary instability; crossflow instability; hot-wire anemometry.;

   Abstract : Rotating-disk flow has been investigated not only as a simple model of cross flow instability to compare with swept-wing flow but also for industrial flow applications with rotating configurations. However the exact nature of laminar-turbulent transi- tion on the rotating-disk flow is still major problem and further research is required for it to be fully understood, in particular, the laminar-turbulent transition process with absolute instability.
