Van Deen, M.S. (author), Simon, J. (author), Zeravcic, Z. (author), Dagois-Bohy, S. (author), Tighe, B.P. (author), Van Hecke, M. (author)We probe the onset and effect of contact changes in soft harmonic particle packings which are sheared quasistatically. We find that the first contact changes are the creation or breaking of contacts on a single particle. We characterize the critical strain, statistics of breaking versus making a contact, and ratio of shear modulus before and...journal article 2014

Fiscaletti, D. (author), Westerweel, J. (author), Elsinga, G.E. (author)The investigation of flows at high Reynolds number is of great interest for the theory of turbulence, in that the large and the small scales of turbulence show a clear separation. But, as the Reynolds number of the flow increases, the size of the Kolmogorov length scale ( ? ) drops almost proportionally. Aiming at achieving the adequate spatial...journal article 2014

Goodrich, C.P. (author), Dagois-Bohy, S. (author), Tighe, B.P. (author), Van Hecke, M. (author), Liu, A.J. (author), Nagel, S.R. (author)Athermal packings of soft repulsive spheres exhibit a sharp jamming transition in the thermodynamic limit. Upon further compression, various structural and mechanical properties display clean power-law behavior over many decades in pressure. As with any phase transition, the rounding of such behavior in finite systems close to the transition...journal article 2014

Hol, F.J.H. (author), Voges, M.J. (author), Dekker, C. (author), Keymer, J.E. (author)Background: Antagonistic interactions mediated by antibiotics are strong drivers of bacterial community dynamics which shape biodiversity. Colicin production by Escherichia coli is such an interaction that governs intraspecific competition and is involved in promoting biodiversity. It is unknown how environmental cues affect regulation of the...journal article 2014

Papachristos, G. (author)Electric appliances are an indispensable part of a household and through their sheer number contribute substantially to its electricity consumption. This paper explores potential reductions in residential appliance electricity consumption in the Netherlands with smart meters, using two perspectives: a bottom up engineering approach and a...conference paper 2014

Pande, S. (author), Ertsen, M. (author), Sivapalan, M. (author)While the proposed model is a rather simple model of a coupled human–water system, it is shown to be capable of replicating patterns of technological, population, production and consumption per capita changes. The model demonstrates that technological change may indeed ameliorate the effects of increasing water scarcity, but typically it does so...journal article 2014

Choupani, R. (author), Wong, S. (author), Tolun, M. (author)The need for adapting video stream delivery over heterogeneous and unreliable networks requires self-adaptive and error resilient coding. Network bandwidth fluctuations can be handled by means of a video coding scheme which adapts to the channel conditions. However, packet losses which are frequent in wireless networks can cause a mismatch...journal article 2014

Klunder, G.A. (author), Taale, H. (author), Kester, L. (author), Hoogendoorn, S.P. (author)This paper introduces a topic which is of growing interest in the traffic control and management community, namely the relation between traffic data quality and the efficiency of traffic management. After some explanatory background and state of the art, it will become clear that no standard approach is available for traffic engineers to...conference paper 2014

Kwakkel, J.H. (author), Haasnoot, M. (author), Walker, W.E. (author)Sustainable water management in a changing environment full of uncertainty is profoundly challenging. To deal with these uncertainties, dynamic adaptive policies that can be changed over time are suggested. This paper presents a model-driven approach supporting the development of promising adaptation pathways, and illustrates the approach using...journal article 2014

Post, R.A.G. (author), Blijlevens, J. (author), Hekkert, P.P.M. (author)The principle of unity-in-variety has recently been shown to affect visual aesthetic appreciation of product designs. We investigated whether this principle can also account for tactile aesthetic appreciation of products. Design students rated nine car keys on unity, variety and aesthetic appreciation through tactile exploration only. Results...conference paper 2014

Blijlevens, J. (author), Thurgood, C. (author), Hekkert, P.P.M. (author), Leder, H. (author), Whitfield, T.W.A. (author)There is a lack of consistency regarding the scales used to measure aesthetic pleasure. They are often chosen ad hoc or derived from other research fields but never validated for design. Moreover, those scales often do not measure aesthetic pleasure in isolation, but instead include its determinants (e.g., novelty). Therefore, we developed a...conference paper 2014

Van der Zwaag, J. (author)The sediment composition of the sea bed is of relevance for various coastal properties such as bed forms, beach slopes and marine ecology. Furthermore it may significantly influence the morphological evolution of the coast. The sediment sorting processes at natural beaches are, however, difficult to distinguish since there can be a both a large...report 2014
