Hellebrandt, L (author), Blom, C.B.M. (author), Steenbergen, RDJM (author)In the coming years numerous existing traffic bridges in cities are subject to re-evaluation. In this paper a new probabilistic traffic load model for short-span bridges is proposed. As an example, site-specific weigh-in-motion data from Rotterdam, the Netherlands, is included in the model. The method proposed in this paper allows for a very...journal article 2016

Orru, C. (author), Blom, A. (author), Chavarrias Borras, V. (author), Ferrara, V (author), Stecca, G. (author)We present a new image analysis technique for measuring the grain size distribution (texture) of the bed surface during flow in a laboratory experiment. A camera and a floating device are connected to a carriage used to take images of the bed surface over the entire flume length. The image analysis technique, which is based on color segmentation...journal article 2016

Blom, A. (author), Viparelli, Enrica (author), Chavarrias Borras, V. (author)There has been quite some debate on the relative importance of particle abrasion and grain size selective transport regarding the river profile form and the associated grain size trends in a graded alluvial stream. Here we present new theoretical equations for the graded alluvial river profile that account for the effects of particle abrasion...journal article 2016

Lenz, T. (author), Dehsari, H.S. (author), Asadi, Kamal (author), Blom, PWM (author), Groen, W.A. (author), de Leeuw, D.M. (author)We demonstrate that ferroelectric memory diodes can be utilized as switching type positive temperature coefficient (PTC) thermistors. The diode consists of a phase separated blend of a ferroelectric and a semiconducting polymer stacked between two electrodes. The current through the semiconducting polymer depends on the ferroelectric...journal article 2016

Zhao, D (author), Asadi, Kamal (author), Groen, W.A. (author), Blom, PWM (author), de Leeuw, D.M. (author)A homogeneous ferroelectric single crystal exhibits only two remanent polarization states that are stable over time, whereas intermediate, or unsaturated, polarization states are thermodynamically instable. Commonly used ferroelectric materials however, are inhomogeneous polycrystalline thin films or ceramics. To investigate the stability of...journal article 2016

Pozo, Susana Del (author), Lindenbergh, R.C. (author), Rodríguez-Gonzálvez, Pablo (author), Blom, J.C. (author), González-Aguilera, Diego (author)Variation in the mineral composition of rocks results in a change of their spectral response capable of being studied by imaging spectroscopy. This paper proposes the use of a low-cost handy sensor, a calibrated visible-very near infrared (VIS-VNIR) multispectral camera for the recognition of different geological formations. The spectral data...journal article 2015

Blom, H.A.P. (author), Sharpanskykh, A. (author)There is broad consensus that situation awareness (SA) plays a key role in agent-based modelling of complex sociotechnical systems. However in the social sciences and human factors literature there are different views on what SA is and how it could be modelled. More specifically, one school of research considers SA as the process of gaining...journal article 2015

Stecca, G. (author), Siviglia, A. (author), Blom, A. (author)Sediment of different size are transported in rivers under the action of flow. The first and still most popular sediment continuity model able to deal with mixed sediment is the so-called active layer model proposed by Hirano (1971, 1972). In this paper, we consider the one-dimensional hydromorphodynamic model given by the Saint-Venant equations...journal article 2014

Viparelli, E. (author), Blom, A. (author), Ferrer-Boix, C. (author), Kuprenas, R. (author)A one-dimensional model that is able to store the stratigraphy emplaced by a prograding delta is validated against experimental results. The laboratory experiment describes the migration of a Gilbert delta on a sloping basement into standing water, i.e., a condition in which the stratigraphy emplaced by the delta front is entirely stored in the...journal article 2014

Orru, C. (author), Chavarrias Borras, V. (author), Uijttewaal, W.S.J. (author), Blom, A. (author)Measurements of spatial and temporal changes in the grain-size distribution of the bed surface and substrate are crucial to improving the modelling of sediment transport and associated grain-size selective processes. We present three complementary techniques to determine such variations in the grain-size distribution of the bed surface in sand...journal article 2014

In view of the expected growth in commercial aviation, significant changes in this socio-technical system are in development both in the USA and Europe....journal article 2013

(author)We have determined the time-resolved transcriptome of the model gram-positive organism B. subtilis during growth in a batch fermentor on rich medium. DNA microarrays were used to monitor gene transcription using 10-minute intervals at 40 consecutive time points. From the growth curve and analysis of all gene expression levels, we identified 4...journal article 2011

Hoogenboom, P.C.J. (author), Van Weelden, C. (author), Blom, C.M.B. (author)In this paper stress concentrations are studied around circular cylindrical openings or voids in a linear elastic continuum. The loading is such that a uniform shear stress occurs in the continuum, which is disturbed by the opening. The shear stress is in the direction of the centre axis of the opening. The stress distribution has been...journal article 2010

Bakker, K.J. (author), Blom, C.B.M. (author)According to modern design codes, such as the Eurocode 7, also Soil Retaining structures should be designed according to Ultimate Limit State analysis, see [1]. From an economic point of view, the design of the lining, i.e. the thickness and reinforcement of it, would be optimal if the loading during construction is less critical than the...journal article 2009
