2. 1. Reinforcement Learning of Locomotion based on Central Pattern Generators

   Author : Cai Li; Tom Ziemke; Robert Lowe; Örjan Ekeberg; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Locomotion learning for robotics is an interesting and challenging area in which the movement capabilities of animals have been deeply investigated and acquired knowledge has been transferred into modelling locomotion on robots. What modellers are required to understand is what structure can represent locomotor systems in different animals and how such animals develop various and dexterous locomotion capabilities. READ MORE

4. 2. The impact of loading-induced stress variation on the seismicity of active faults

   Author : Yiting Cai; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; stress variation; Coulomb stress change; subduction zone; Seismicity;

   Abstract : Surface loads such as the ocean, atmosphere, and continental water, constantly modify the stress field of the Earth’s crust. Most earthquakes occur at tectonic plate boundaries and such stress perturbations on the active faults at the plate boundaries may trigger earthquakes. READ MORE

5. 3. The Many Facets of bicoid Gradient Formation in Drosophila

   Author : Xiaoli Cai; Stefan Baumgartners grupp Utvecklingsbiologi i invertebrater; []
   Keywords : Drosophila; bicoid; gradient formation; ARTS model; cortical microtubule; drug;

   Abstract : In Drosophila, the Bicoid protein servers as paradigm as the first identified morphogen, whose concentration gradient provides the initial positional information in the anterior half of the embryo. There, it differentially activates segmentation genes, in particular the gap genes. READ MORE

6. 4. Multithreaded PDE Solvers on Non-Uniform Memory Architectures

   Author : Markus Nordén; Michael Thuné; Sverker Holmgren; Xing Cai; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; PDE solver; high-performance; NUMA; UMA; OpenMP; MPI; data migration; data replication; thread scheduling; data affinity; Beräkningsvetenskap; Scientific Computing;

   Abstract : A trend in parallel computer architecture is that systems with a large shared memory are becoming more and more popular. A shared memory system can be either a uniform memory architecture (UMA) or a cache coherent non-uniform memory architecture (cc-NUMA). READ MORE

7. 5. Finite Element Computations on Multicore and Graphics Processors

   Author : Karl Ljungkvist; Jarmo Rantakokko; Xing Cai; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Finite Element Methods; GPU; Matrix-Free; Multigrid; Transactional Memory; Scientific Computing; Beräkningsvetenskap;

   Abstract : In this thesis, techniques for efficient utilization of modern computer hardwarefor numerical simulation are considered. In particular, we study techniques for improving the performance of computations using the finite element method. READ MORE
