2. 1. Hierarchical Variance Reduction Techniques for Monte Carlo Rendering

   Author : Petrik Clarberg; Institutionen för datavetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; computer graphics; Monte Carlo methods; importance sampling; hierarchical techniques; rendering;

   Abstract : Ever since the first three-dimensional computer graphics appeared half a century ago, the goal has been to model and simulate how light interacts with materials and objects to form an image. The ultimate goal is photorealistic rendering, where the created images reach a level of accuracy that makes them indistinguishable from photographs of the real world. READ MORE

   Abstract : The history of surgery is nearly as old as the human race. Control of wound infection has always been an essential part of any surgical procedure, and is still an important challenge in hospital operating rooms today. For patients undergoing surgery there is always a risk that they will develop some kind of postoperative complication. READ MORE

5. 3. Evaluation of the infrared reflection method for saccadic eye movement velocity analysis

   Author : Frank Träisk; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Infrared reflection; Scleral search coil; Saccade; Main sequence; Eye-tracking.;

   Abstract : Saccades are rapid eye movements that change the orientation of the eyes onto objects of interest. In an every day situation saccadic eye movements are used for e.g. reading, scanning objects and enviromnents. READ MORE

6. 4. P-type and polarization doping of GaN in hot-wall MOCVD

   Author : Alexis Papamichail; Vanya Darakchieva; Anelia Kakanakova-Gueorguieva; Jr-Tai Chen; Zhaoxia Bi; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The devolopment of group-III nitride semiconductor technology continues to expand rapidly over the last two decades. The indium nitride (InN), gallium nitride (GaN) and aluminum nitride (AlN) compounds and their alloys are direct bandgap semiconductors with a wide bandgap range, spanning from infrared(IR) to deep-ultraviolet (UV), enabling their utilization in optoelectronic industry.

7. 5. Structural and elastic properties of InN and InAlN with different surface orientations and doping

   Author : Mengyao Xie; Vanya Darakchieva; Jens Birch; Enrique Calleja; Linköpings universitet; []
   Keywords : ;

   Abstract : Group–III nitrides, InN, GaN, AlN, and their alloys, have revolutionized solid state lighting and continue to attract substantial research interest due to their unique properties and importance for optoelectronics and electronics. Among the group–III nitrides, InN has the lowest effective electron mass and the highest electron mobility, which makes it suitable for high–frequency and high power devices. READ MORE
