Van Beek, V.M. (author)Backward erosion piping is an internal erosion mechanism during which shallow pipes are formed in the direction opposite to the flow underneath water-retaining structures as a result of the gradual removal of sandy material by the action of water. It is an important failure mechanism in both dikes and dams where sandy layers are covered by a...doctoral thesis 2015

To reveal the scale-dependences of the transport of turbulent energy in a channel flow, the constituents of the budget equation of turbulent energy for the Fourier modes of velocity fluctuations are computed by using direct numerical simulations. At each height in the buffer and overlap regions, the transport in the wall-normal direction by the...conference paper 2015

Van Oort, N. (author), Van Leusden, R. (author)Hoewel het verbeteren van de betrouwbaarheid van het openbaar vervoer (OV) vaak één van de belangrijkste doelen is van OV-projecten, ontbreekt in maatschappelijke kostenbatenanalyses (MKBA’s) vaak expliciete, kwantitatieve aandacht voor de verwachte baten hiervan. In dit paper presenteren we een methodiek die het mogelijk maakt deze baten...journal article 2015

Miller, Seirgei (author), Bijleverld, Frank (author), Erkens, S. (author), Anupam, K. (author)Governments, regulatory bodies and road authorities all push for and promote sustainability. Contractors respond with strategies to reduce their carbon footprints. Besides optimising their asphalt production and logistics processes, companies are investing in the development of low energy asphalt mixes. Warm Mix Asphalt (WMA) is such an asphalt...journal article 2015

Shen, K. (author)Nanostructured materials are featured by providing a variety of favourable electrical properties, as the reduced ion and electron transport paths enable significant enhancement on (de)intercalation rates and hence high power. For TiO2 anatase, nano-sizing results in a curved open cell voltage profile with a much shorter plateau region in...doctoral thesis 2014

Lemmens, M.J.P.M. (author)The launch of SPOT 7 on 30 June 2014 at 6:22 a.m. CET completed the constellation of four optical spacecraft operating in the same orbit. The constellation further consists of twin sister SPOT 6 and Pléiades 1A and 1B. To mark the occasion, the author discusses the features of the extended family of 7 SPOT satellites here.journal article 2014

Klievink, A.J. (author), Janssen, M.F.W.H.A. (author)Information infrastructures of businesses and government are increasingly interwoven and highly dependent on each other. Though often referred to as sociotechnical innovations, the development of these information infrastructures often has a technological focus. The related and even concurrent development of new social practices is understudied....journal article 2014

Suharti, S. (author), Wang, M. (author), De Vries, S. (author), Ferry, J.G. (author)Rnf complexes are redox-driven ion pumps identified in diverse species from the domains Bacteria and Archaea, biochemical characterizations of which are reported for two species from the domain Bacteria. Here, we present characterizations of the redox-active subunits RnfG and RnfB from the Rnf complex of Methanosarcina acetivorans, an acetate...journal article 2014

Zhang, L. (author)The research in ultrasonic processing for metallurgical application shows a promising influence on improving casting properties of aluminium alloys. The principle of ultrasonic processing is introduction of acoustic waves with a frequency higher than 17 kHz into liquid metal. Several promising beneficial effects caused by ultrasonic processing...doctoral thesis 2013

Grzech, A. (author)In this thesis representatives of two different types of materials for potential hydrogen storage application are presented. Usage of either nanoporous materials or metal hydrides has both operational advantages and disadvantages. A main objective of this thesis is to characterize the hydrogen storage mechanism of selected Metal-Organic...doctoral thesis 2013

van der Put, T.A.C.M. (author), Leijten, A.J.M. (author)By the earlier derived theory of the embedding strength, based on limit design, it is possible to explain the extremely high embedding strength of nailed particle board to wood joints leading to a new exact failure equation for the embedding strength as necessary correction for design and for the Codes.conference paper 2012

Heeres, R.W. (author), Zwiller, V. (author)We explore the dynamics of superconducting single-photon detectors (SSPDs) on the picosecond time-scale using a correlated photon-pair source based on spontaneous parametric downconversion (SPDC), corresponding to a pump-probe experiment at the single-photon level. We show that the detector can operate in a regime where the two-photon detection...journal article 2012

Ge, X. (author), Wang, H. (author)Many networks are characterized by the presence of communities, densely intra-connected groups with sparser inter-connections between groups. We propose a community overlay network representation to capture large-scale properties of communities. A community overlay Go can be constructed upon a network G, called the underlying network, by (a)...journal article 2012
