Peruzzini, D. (author), Viti, J. (author), Tortoli, P. (author), Verweij, M.D. (author), De Jong, N. (author), Vos, H.J. (author)Currently, in medical ultrasound contrast agent (UCA) imaging the second harmonic scattering of the microbubbles is regularly used. This scattering is in competition with the signal that is caused by nonlinear wave propagation in tissue. It was reported that UCA imaging based on the third or higher harmonics, i.e. “superharmonic” imaging, shows...conference paper 2015

De Jong, P. (author), Van Dooren, E.J.G.C. (author), Den Heijer, A.C. (author)In positioning the design school versus the business school, the management game as an educational module in the last semester of the architectural bachelor in Delft is illustrative for the possible synthesis between real estate and architecture. The explicit approach of design, as applied in Delft and many other institutes for architecture, and...conference paper 2015

Bogers, B.A. (author), Van den Berg, D. (author), Zijlstra, S. (author), De Jong, P. (author)Considering the small addition in the housing supply of newly built dwellings, meeting sustainable goals in the Netherlands will have to come from the existing housing supply. TU Delft’s Solar Decathlon 2014 design focuses on achieving a zero energy renovation that is both sustainable as well as attractive for inhabitants of the most frequent...conference paper 2015

Van der Velden, W.C.P. (author), Van Zuijlen, A.H. (author), De Jong, A.T. (author), Bijl, H. (author)The flow around a beveled flat plate model with an asymmetric 25 degrees trailing edge with three rounding radii is analyzed using a Navier-Stokes based open source software package OpenFOAM in order to predict the aeroacoustic properties of the models. A Large Eddy Simulation with a dynamic Smagorinsky and implicit model are used as closure...conference paper 2015

Steenbergen, M.J.M.M. (author), De Jong, E. (author), Zoeteman, A. (author)During train operation, geometrical irregularities develop in soil-supported ballasted railway tracks as a function of born tonnage. This form of degradation is combatted by periodic maintenance in the form of tamping by specially equipped trains in order to guarantee predefined levels of structural performance. The growth of irregular...conference paper 2015

Van der Velden, W.C.P. (author), Van Zuijlen, A.H. (author), De Jong, A.T. (author), Bijl, H. (author)A Large Eddy Simulation (LES) with four different closure models are analyzed in OpenFOAM, an open source Computional Fluid Dynamics (CFD) package and validated for the determination of the streamwise and spanwise coherence length of the pressure field below a turbulent boundary layer at low Reynolds numbers. Matching results are found for outer...conference paper 2014

Auping, W.L. (author), De Jong, S. (author), Pruyt, E. (author), Kwakkel, J.H. (author)The US’ shale gas revolution, a spectacular increase in natural gas extraction from previously unconventional sources, has led to considerable lower gas prices in North America. This study focusses on consequences of the shale gas revolution on state stability of traditional oil and gas exporting countries in the vicinity of the EU. For this...conference paper 2014

(author), Hulscher, S.J.M.H. (author), Lansen, A.J. (author)This paper explores an alternative method to determine extreme surge levels at the Dutch Coast. For this exploration, specific focus is on the extreme water level at Hoek van Holland, The Netherlands. The alternative method has been based on a joint probability model of the storm characteristics at the North Sea. The intent of this method is to...conference paper 2014

Knoop, V.L. (author), De Jong, D.M. (author), Hoogendoorn, S.P. (author)The Macroscopic or Network Fundamental Diagram (NFD) describes the relationship between the network flow and the number of travellers within the network. The shape of the NFD is important for control purposes like perimeter control or routing. However, it is unknown how the network structure influences the shape of the NFD. This is studied in...conference paper 2014

Knoop, V.L. (author), De Jong, D.M. (author), Hoogendoorn, S.P. (author)It is analyzed what the effect is of the exact network structure on the shape of the Network Fundamental Diagram (NFD). In order to do so, a tool is developed which can create random networks for which the aggregated properties are the same. Using this tool, different urban networks with the same properties are designed. They show different NFDs...conference paper 2014

Knoop, V.L. (author), De Jong, D.M. (author), Hoogendoorn, S.P. (author)The Macroscopic or Network Fundamental Diagram (NFD) describes the network performance as a function of the number of vehicles. Even if the network has the same roadway length, type of roads, number of intersections and traffic light setting strategy, the shape of the NFD changes. Therefore, the NFD needs to be calculated or simulated separately...conference paper 2013

Soeter, J.P. (author), De Jong, P.

The recession in 2008/2009 -and again in 2011/2012- strengthens the uncertainties about the future. Nevertheless the real estate market was in...conference paper 2012
