Sprung, D. (author), Sucher, E. (author), van Eijk, A.M.J. (author), Eisele, C. (author), Seiffer, D. (author), Stein, K. (author)A field trial was performed in the arid scrub area of White Sands, NM /USA in October 2017 investigating the atmospheric influence on imaging and sensor performance. In this paper we focus on the strength of optical turbulence. Optical turbulence is described by the structure function parameter of the refractive index Cn 2. It is responsible for...conference paper 2018

de Jong, A.T. (author), Golliard, J. (author)An investigation is performed on the scalability of broadband noise sources from separated flows in internal pipe systems. Broadband sources from for example wellhead chokes, bends and valves can potentially excite subsea manifolds through fluid acoustic coupling and fluid structural coupling. The focus of the current work is evaluation and...conference paper 2013

Offermans, P. (author), Tong, H.D. (author), van Rijn, C.J.M. (author), Merken, P. (author), Brongersma, S.H. (author), Crego-Calama, M. (author), TNO Industrie en Techniek (author)Palladium nanowires were fabricated on silicon substrates using conventional microfabrication techniques. Sensors based on such nanowires show a reversible response to hydrogen concentrations as low as 27 ppm with response times varying from 5 s (H2 concentrations >20%) to 30 s (H2 concentrations <100 ppm) at room temperature. The response times...article 2009

Steeghs, P. (author), Kester, L. (author), Gelsema, S. (author)The use of the Radon transform and the Wigner-Radon power spectrum for ISAR motion compensation is described. It is shown that the local Radon power spectrum is closely related to the Cohen's class of quadratic time-frequency representations in a similar way as the Radon and Fourier transform are related. The peak of the local Radon transform is...conference paper 2002

Philippens, I.H.C.H.M. (author), Melchers, B.P.C. (author), de Groot, D.M.G. (author), Wolthuis, O.L. (author)It is known that rats poisoned with near-lethal doses of pinacolyl methylphosphonofluoridate (soman) develop brain lesions, particularly when convulsions are induced. When rats were intoxicated with a LD50 of soman and treated immediately thereafter with a combination of low doses of atropine and diazepam (LOW AS/DZ treatment), large decrements...article 1992
