2. 1. Laser Diagnostics Applied to Lean Premixed Swirling Flames - Simultaneous Flow Field and Scalar Measurements

   Author : Per Petersson; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Volumetric Velocimetry; Low-swirl Flames; Premixed Flames; Turbulent Combustion; Particle Image Velocimetry; Laser Diagnostics; A.2014:Petersson; Combustion Diagnostics;

   Abstract : The work reported here includes experimental studies of lean premixed swirling flames. Various laser-based optical diagnostic techniques were used to collect information under different operational conditions. Combined flow- and scalar field measurements were performed at high repetition rates for detailed studies of the turbulent flames. READ MORE

4. 2. Process Efficiency and Capacity Flexibility : Developing a Support Tool for Capacity Decisions in Manual Assembly Systems

   Author : Per Petersson; Peter Holmstedt; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Productivity is an important measure of competitiveness and one important factor influencing productivity is capacity utilisation. In order to achieve high productivity, there should be no more capacity in a system than is required by the current demand rate. READ MORE

5. 3. Spontaneous Movements during Sleep Guide Spinal Self-organization: Formation and Expression of a Memory Trace

   Author : Per Petersson; Neurofysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; neuropsychology; Neurology; long-term memory; somatosensory; receptive field; learning; sensorimotor; developmental; neurophysiology; neurofysiologi; neuropsykologi;

   Abstract : During development, information about the three-dimensional shape and mechanical properties of the body is laid down in the synaptic connectivity of sensorimotor systems through adaptive mechanisms. In spinal reflex systems, this enables the fast transformation of complex sensory information into adequate correction of movements. READ MORE

7. 5. Ion Beam Analysis of First Wall Materials Exposed to Plasma in Fusion Devices

   Author : Per Petersson; Göran Possnert; Anders Hallén; Marek Rubel; Eduardo C. Alves; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ion beam analysis; Microbeam; Plasma wall interaction; Deuterium; Beryllium; Carbon fibre composites; Divertor; Nuclear reaction analysis; Helium-3; Plasma physics with fusion; Plasmafysik med fusion; Ion Physics; Jonfysik;

   Abstract : One major step needed for fusion to become a reliable energy source is the development of materials for the extreme conditions (high temperature, radioactivity and erosion) caused by hot plasmas. The main goal of the present study is to use and optimise ion beam methods (lateral resolution and sensitivity) to characterise the distribution of hydrogen isotopes that act as fuel. READ MORE
