Van Vledder, G.J. . (author), Adema, J. (author)For two historical storms the water levels and currents in the Wadden Sea were simulated using the so-called model-train of Rijkswaterstaat. The first storm of 1 Nov. 2006 generated exceptionally high water levels in the Eems-Dollard estuary. The second storm of 18 Jan. 2007 was also scaled up to represent a 1 in 4000 year design storm. In...report 2007

Wapenaar, C.P.A. (author)Acoustic, electromagnetic, elastodynamic, poroelastic, and electroseismic waves are all governed by a unified matrix-vector wave equation. The matrices in this equation obey the same symmetry properties for each of these wave phenomena. This implies that the wave vectors for each of these phenomena obey the same reciprocity theorems. By...journal article 2007

Colonna, P. (author), Guardone, A. (author), Nannan, N.R. (author)This paper presents a new class of Bethe-Zel’dovich-Thompson fluids, which are expected to exhibit nonclassical gasdynamic behavior in the single-phase vapor region. These are the linear and cyclic siloxanes, light silicon oils currently employed as working fluids in organic Rankine cycle turbines. State-of-the-art multiparameter equations of...journal article 2007

Khalili Amiri, P.K. (author), Rejaei, B. (author), Vroubel, M. (author), Zhuang, Y. (author)The authors report on the observation of nonreciprocal spin wave propagation in a thin ( ? 200?nm) patterned Ni–Fe stripe. The spin wave transmission spectrum is measured using a pair of microstrip lines as antennas. The nonreciprocity of surface wave dispersion brought about by an adjacent aluminum ground leads to a nonreciprocal coupling of...journal article 2007

Pullen, T. (author), Allsop, N.W.H. (author), Bruce, T. (author), Kortenhaus, A. (author), Schüttrumpf, H. (author), Van der Meer, J.W. (author)The manual has been intended to assist engineers who are already aware of the general principles and methods of coastal engineering. The manual uses methods and data from research studies around Europe and overseas so readers are expected to be familiar with wave and response parameters and the use of empirical equations for prediction. Users...report 2007

Simonov, A.N. (author), Grabarnik, S. (author), Vdovine, G.V (author)We have investigated the possibility of using transparent stretchable diffraction gratings for spectrometric applications. The gratings were fabricated by replication of a triangular-groove master into a transparent viscoelastic. The sample length, and hence the spatial period, can be reversibly changed by mechanical stretching. When used in a...journal article 2007

Reniers, A.J.H.M. (author), MacMahan, J.H. (author), Thornton, E.B. (author), Stanton, T.P. (author)Numerical computations are used to explain the presence of very low frequency motions (VLFs), with frequencies less than 0.004 Hz, in the rip current velocity signals observed during the Rip-current field Experiment (RIPEX) field experiment. Observations show that the VLF motions are most intense within the surfzone and then quickly taper off in...journal article 2007

Bottema, M. (author)In the period 1997-2007, an extensive wind and wave measuring campaign has been carried out on Lake IJssel and Lake Sloten in The Netherlands. The aim of this campaign was to gather and analyse welldocumented wind and wave measurements of high quality, for a range of fetch, depth and (strong) wind conditions. The data should serve a number of...report 2007

Heineke, D. (author), Verhagen, H.J. (author)To assess the hydraulic performance of coastal structures - viz. wave run-up, overtopping and reflection - and to evaluate the stability of the armour layers, use is made of the dimensionless surf similarity parameter, as introduced by Battjes (1974). The front side slope of the structure and the wave steepness are combined in this parameter,...conference paper 2007

Beckers, J. (author), Doorn, N. (author), Van der Klis, H. (author)The goal of the uncertainty analyses within the SBW Wadden Sea project is to find out which accuracy in HBC can be achieved, given the current state of scientific knowledge and technical instruments. Furthermore, we wish to quantify the contribution of the SWAN model and other components to the overall uncertainty in HBC. In order to answer...report 2007

Tuan, Thieu Quang (author)Natural or unintended breaching can be catastrophic, causing loss of human lives and damage to infrastructures, buildings and natural habitats. Quantitative understand-ing of coastal barrier breaching is therefore of great importance to vulnerability as-sessment of protection works as well as to spatial planning against flooding hazards. The...doctoral thesis 2007

Simonov, A.N. (author), Vdovine, G.V. (author), Loktev, M. (author)We present a prototype of an adaptive intraocular lens based on a modal liquid-crystal spatial phase modulator with wireless control. The modal corrector consists of a nematic liquid-crystal layer sandwiched between two glass substrates with transparent low- and high-ohmic electrodes, respectively. Adaptive correction of ocular aberrations is...journal article 2007

On land, the near surface disturb the data severely, due to its strongly heterogeneous character.

Cuomo, G. (author)In most developed coastal areas, seawalls protect towns, road, rail and rural infrastructure against wave overtopping. Similar structures protect port installations worldwide, and may be used for cliff protection. When a large tidal excursion and severe environmental conditions concur to expose seawalls and vertical face breakwaters to wave...report 2007
