Dunham has taught physics for 34 years at Middlebury College in Middlebury, Vermont, where he is now William R. Kenan Jr. Professor of Natural Sciences. He currently conducts experimental research in nonlinear dynamics. He is using HPC techniques at the workstation level to analyze large data sets from experiments that can be performed in a small-college laboratory. He received the Bachelor of Science degree in physics from the University of Washington in 1975 and the Ph.D. in physics from Stanford University in 1981. Presentation Savitzky-Golay Filter Algorithm for Large One-Dimensional Data Sets A chaotic pendulum experiment in our laboratory performs about 275 million digitized angle measurements in a 24-hour day. A Poincaré plot of the raw data shows significant and unacceptable discretization effects from the optical rotary encoder used to measure angle. The raw data is therefore passed through a Savitzky-Golay (SG) filter [...]

Speaker Pablo González de Aledo Marugán, Postdoctoral Research Assistant, Imperial College of London Pablo González de Aledo studied telecommunications engineering at thec University of Cantabria, Santander, Spain, and finished his studies at the Network-on-Chip team in ST-Microelectronics Grenoble, France. After working in the modeling and simulation of high-performance, multi-core and heterogeneous platforms for some European projects he became interested in the theory behind formal methods and worst-case-execution-time and moved to the Department of Computing at Macquarie University, Sydney, Australia, to complement his Ph. D. studies. He is now a Postdoctoral Research Assistant at Imperial College of London. Presentation An optimization approach for the computational modeling of biological development Current research in the field of computational biology often involves simulations on high-performance computer clusters. It is crucial that the code of such simulations is very efficient and correctly reflects the model [...]
