Hussong, J. (author), Breugem, W.P. (author), Westerweel, J. (author)In this numerical study we investigate the flow induced by metachronal coordination between beating cilia arranged in a densely packed layer by means of a continuum model. The continuum approach allows us to treat the problem as two-dimensional as well as stationary, in a reference frame moving with the speed of the metachronal wave. The model...journal article 2011

Castaldo, V. (author), Withagen, J. (author), Hagen, C. (author), Kruit, P. (author), Van Veldhoven, E. (author)In recent years, novel ion sources have been designed and developed that have enabled focused ion beam machines to go beyond their use as nano-fabrication tools. Secondary electrons are usually taken to form images, for their yield is high and strongly dependent on the surface characteristics, in terms of chemical composition and topography. In...journal article 2011

(author), Orzechowska, G.E. (author), Kidd, R.D. (author), Van Sluis, C.A. (author), Foing, B.H. (author)Several robotic exploration missions will travel to Mars during this decade to investigate habitability and the possible presence of life. Field research at Mars analogue sites such as desert environments can provide important constraints for instrument calibration, landing site strategies and expected life detection targets. We have...journal article 2011

Ter Brake, M.C. (author), Schuttelaars, H.M. (author)In many tidal embayments, complex patterns of channels and shoals are observed. To gain a better understanding of these features, an idealized model, that describes the interaction of water motion, sediment transport and bed evolution in a semi-enclosed, rectangular basin, is developed and analysed. To explain the initial formation of channels...journal article 2011

Wang, Z. (author), Krasnov, O.A. (author), Babur, G.P. (author), Ligthart, L.P. (author), Van der Zwan, F. (author)This paper presents the development of a reconfigurable receiver to undertake challenging signal processing tasks for a novel polarimetric radar system. The field-programmable gate arrays (FPGAs)-based digital receiver samples incoming signals at intermediate frequency (IF) and processes signals digitally instead of using conventional analog...journal article 2011

Yang, B. (author), Yarovoy, A.G. (author), Valavan, A.S.E. (author), Buisman, K. (author), Shoykhetbrod, O. (author)In this paper a novel differentially fed Ultra-Wide Band (UWB) antenna in low-temperature co-fired ceramics (LTCC) technology to be used in the 60 GHz band for integrated RF front-ends is presented. The antenna is based on the aperture stacked patch fed via H-shaped aperture to achieve more than 10 GHz operational bandwidth. The antenna is fed...journal article 2011

Liberal, I. (author), Caratelli, D. (author), Yarovoy, A. (author)The design and full-wave analysis of an antenna system for ultra-wideband radio direction finding applications is presented. The elliptical dipole antenna is selected as antenna element due to its robust circuital and radiation properties. The influence of the conformal deformation on the antenna performance has been studied in details. A...journal article 2011

Felderhof, B.U. (author), Ooms, G. (author)The flow of a viscous compressible fluid in a circular tube generated by a sudden impulse at a point on the axis is studied on the basis of the linearized Navier–Stokes equations. A no-slip boundary condition is assumed to hold on the wall of the tube. An efficient numerical scheme has been developed for the calculation of flow velocity and...journal article 2011

Dolstra, E. (author), Löh, A. (author), Pierron, N. (author)Existing package and system configuration management tools suffer from an imperative model, where system administration actions such as package upgrades or changes to system configuration files are stateful: they destructively update the state of the system. This leads to many problems, such as the inability to roll back changes easily, to...journal article 2010

Fasoula, A. (author), Driessen, H. (author), Van Genderen, P. (author)Taking into account sparsity of the reflectivity function of several radar targets of interest, efficient low-complexity automatic target recognition (ATR) systems can be designed. Such ATR systems would be based on two-dimensional (2D) spatial target models of low dimensionality, where critical information on the radar target signature is...journal article 2010

(author)This paper presents an experimental investigation of two approaches to short-range radar imaging at microwaves by means of ultra-wideband (UWB) technology. The first approach represents a classical synthetic aperture radar (SAR) that employs a transmit–receive antenna pair on mechanical scanner. The second one makes use of a multiple input...journal article 2010

Bijlard, M.J. (author), Oliemans, R.V.A. (author), Portela, L.M. (author), Ooms, G. (author)The results of point-particle Eulerian–Lagrangian direct numerical simulation (DNS) calculations of dilute particle-laden turbulent channel flow are used to study the effect of the particles on the local flow topology. It is found that in the viscous sublayer, the flow becomes increasingly more two-dimensional as the two-way coupling effect (due...journal article 2010
