Lu, G. (author), Hagan, M.E. (author), Häusler, K. (author), Doornbos, E.N. (author), Bruinsma, S. (author), Anderson, B.J. (author), Korth, H. (author)We present a case study of the 5 April 2010 geomagnetic storm using observations and numerical simulations. The event was driven by a fast-moving coronal mass ejection and despite being a moderate storm with a minimum Dst near ?50 nT, the event exhibited elevated thermospheric density and surges of traveling atmospheric disturbances (TADs) more...journal article 2014

Lu, H. (author), Xu, T. (author), Nikookar, H. (author), Ligthart, L.P. (author)In this paper, we investigate the diversity, capacity and complexity issues of cooperative Zero-Padding (ZP)-Orthogonal FrequencyDivisionMultiplexing (OFDM) communication. We consider cooperative ZP-OFDM communication over a multipath Rayleigh channel and with multiple Carrier Frequency Offsets (CFOs) existing at different relays. We use a...journal article 2011

(author)In this work, we demonstrate an innovative approach, combing a novel active screen plasma (ASP) technique with green chemical synthesis, for a direct fabrication of uniform Pt nanowire arrays on large-area supports. The ASP treatment enables in-situ N-doping and surface modification to the support surface, significantly promoting the uniform...journal article 2014

Lu, S. (author), Li, J. (author), Van Zuylen, H. (author)Different aspects of the traffic control system in the CBD of Changsha have been evaluated. A general issue is the safety conditions, which are evaluated qualitatively. The second issue is the low saturation flow observed on the intersections, that appear to be 20 to 30% lower than the ones in comparable situations in Europe or North America....journal article 2012

Dilner, D. (author), Lu, Q. (author), Mao, H. (author), Xu, W. (author), Van der Zwaag, S. (author), Selleby, M. (author)This paper demonstrates the use of a new model consisting of a genetic algorithm in combination with thermodynamic calculations and analytical process models to minimize the processing time during a vacuum degassing treatment of liquid steel. The model sets multiple simultaneous targets for final S, N, O, Si and Al levels and uses the total slag...journal article 2014

Otto, T. (author), Lu, J. (author), Chandra, M. (author)Polarisation diversity in radar remote sensing proved to be very successful in a variety of applications. Hydrometeors as raindrops or ice crystals are anisotropic radar targets giving rise to the use of polarisation diversity in weather radars. One advanced polarimetric weather radar is DLR's POLDIRAD in Oberpfaffenhofen. The huge data archive...journal article 2009

(author)The 2010 Eyjafjallajokull volcano eruption had serious consequences to civil aviation. This has initiated a lot of research on volcanic ash transport forecast in recent years. For forecasting the volcanic ash transport after eruption onset, a volcanic ash transport and diffusion model (VATDM) needs to be run with Eruption Source Parameters (ESP)...journal article 2015

Lu, S. (author), Lin, X. (author), Heemink, A.W. (author), Fu, G. (author), Segers, A.J. (author)Volcanic ash forecasting is a crucial tool in hazard assessment and operational volcano monitoring. Emission parameters such as plume height, total emission mass, and vertical distribution of the emission plume rate are essential and important in the implementation of volcanic ash models. Therefore, estimation of emission parameters using...journal article 2015
