2. 1. Ions interacting with macromolecules : NMR studies in solution

   Author : Yuan Fang; Istvan Furo; Monika Schönhoff; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; electrophoretic NMR; diffusion NMR; specific ion effects; Hofmeister; ion binding; Kemi; Chemistry;

   Abstract : Specific ion effects, identified for more than hundred years, play an important role in a wide range of phenomena and applications. Several mechanisms such as direct ion interaction with molecules have been suggested to explain these effects, but quantitative experimental evidence remains scarce. READ MORE

4. 2. Failure diagnostics using support vector machine

   Author : Yuan Fuqing; Thomas Lindblad; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

   Abstract : Failure diagnostics is an important part of condition monitoring aiming to identify incipient failures in early stages. Accurate and efficient failure diagnostics can guarantee that the operator makes the correct maintenance decision, thereby reducing the maintenance costs and improving system availability. READ MORE

5. 3. Machine Behavior Development and Analysis using Reinforcement Learning

   Author : Yuan Gao; Ginevra Castellano; Elin Anna Topp; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforcement learning; robotics; human robot interaction; Computer Science; Datavetenskap;

   Abstract : We are approaching a future where robots and humans will co-exist and co-adapt. To understand how can a robot co-adapt with humans, we need to understand and develop efficient algorithms suitable for our interactive purposes. Not only it can help us to advance the field of robotics but also it can help us to understand ourselves. READ MORE

6. 4. Evidence for adaptive variation at the genes coding for cytosolic phosphoglucose isomerase (PGIC) in Festuca ovina L

   Author : Yuan Li; Biodiversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; 3-D protein structure; purifying selection; positive selection; cDNA sequences; local adaptation; alvar grasslands; Festuca ovina; Phosphoglucose isomerase; PgiC loci; SNPs; nucleotide polymorphism; horizontal gene transfer;

   Abstract : The gene (Pgi) encoding the enzyme phosphoglucose isomerase (PGI) which plays a central role in the main pathways of carbon metabolism has been shown to be of adaptive significance in a wide range of different species. Earlier studies of enzyme electromorph variation in the grass Festuca ovina suggest that variation in cytosolic PGI (PGIC) may be involved in the adaptive response of F. READ MORE

7. 5. Mathematical Models and Algorithms for Wireless Network Design and Optimization

   Author : Yuan Li; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; max-min flow; directional antenna; optimization; integer programming; cellular backhaul network design; delay minimization; SINR; compatible set;

   Abstract : Optimization techniques always play an important role in designing high-performance wireless systems. This presented thesis studies a selected set of optimization problems for different kinds of wireless networks, making use of mathematical programming techniques to find optimal solutions and of efficient heuristics to find near-optimal solutions.
