![]() ![]() Notable developments are the image deformation technique, Tomographic PIV for 3D ow velocity measurements and its use to Preface XI quantitatively determine pressure uctuations and acoustic emissions in wind tunnel experiments. The research interests cover the development of particle image velocimetry (PIV) and its applications to high-speed aerodynamics in the supersonic and hypersonic regime. Promoted and supervised more than 20 PhDs. European project coordinator (AFDAR, Advanced Flow Diagnostics for Aeronautical Research, 2010-2013). Recipient of Marie-Curie grant (1999), Dutch Science Foundation VIDI grant (2005) and of the European Research Council grant (ERC, 2009). Currently director of the AWEP department (Aerodynamics, Wind Energy, Flight Performance and propulsion). Starting director of Aerospace Engineering Graduate School (2012). Since 2008 he is full professor of Aerodynamics and acts as head of section since 2010. in 2000 (von Karman Institute, Theodor von Karman prize) and joined TU Delft at the faculty of Aerospace Engineering in the Aerodynamics Section in the same year. Since 1997 he has been working in the development and application of planar velocimetry techniques (PIV and Doppler Global Velocimetry (DGV)) at the Institute of Propulsion Technology of DLR and now is heading the Department of Engine Measurement Techniques there.įulvio Scarano graduated in Aerospace Engineering at University of Naples (1996). In 1994 he joined DLR Goettingen's measurement sciences group as part of an exchange program between Caltech and DLR. in Engineering Sciences in 1992, he assumed post-doctoral positions first at the Institute for Nonlinear Science (INLS) at UCSD, then at the Graduate Aeronautical Laboratories at the California Institute of Technology (Caltech). Subsequent graduate work in experimental fluid mechanics at UCSD lead to the development of several non-intrusive measurement techniques for application in water (particle tracing, 3-D particle tracking, digital PIV). He is professor at the University of Hannover and head of the Department of Helicopters at DLR's Institute of Aerodynamics and Flow Technology in Goettingen.Ĭhristian Willert received his Bachelor of Science in Applied Science from the University of California at San Diego (UCSD) in 1987. ![]() Markus Raffel additionally works on the development of other ow metrology like the background-oriented schlieren technique and the differential infrared thermography. In this process he applied the method to a number of aerodynamic problems mainly in the context of rotorcraft investigations. He started working on PIV at the German Aerospace Center (DLR) in 1991 with emphasis on the development of PIV recording techniques in high-speed ows. Preserves useful metadata (Android 9-patches, aPNG, etc.Markus Raffel received his degree in Mechanical Engineering in 1990 from the Technical University of Karlsruhe, his doctorate in Engineering in 1993 from the University of Hannover and his lecturer qualification (Habilitation) from the Technical University Clausthal, in 2001.Losslessly auto-rotates JPEG photographs according to Exif Orientation tag.Strips excessive metadata (Exif, XMP, IPTC, comments, etc.).Full color management with ICC v4 profile support.Advanced-quality metrics based on human perception.Fast parallel processing on modern multi-core CPUs.Negligible degradation on subsequent runs.Lossy (visually lossless) and lossless optimizations. ![]() Simple native GUI and universal CLI clients are built to work efficiently across many different platforms on desktops and servers. Maximum compression ratio is achieved by exhaustively trying various compression parameters and image-data structures, using novel and traditional heuristics. ![]() It uses advanced metrics to automatically adjust image quality for up to 10x smaller image files that are visually perceived as originals. Optimage is an advanced image-optimization tool to minimize images in a visually lossless way for websites, apps, storage, and sharing. ![]()
