Blom, D.S. (author)Fluid-structure interaction simulations are crucial for many engineering problems. For example, the blood flow around new heart valves or the deployment of airbags during a car crash are often modeled with fluidstructure interaction simulations. Also, to design safe parachutes, simulations are carried out to model the unsteady deformations of...doctoral thesis 2017

Arkesteijn, L. (author), Labeur, R.J. (author), Blom, A. (author)When rivers are forced by statistically invariant boundary conditions (i.e. an upstream water discharge, upstream sediment discharge and downstream base level that fluctuate around constant mean values), and are not subject to any forcing with a temporal trend (e.g. no uplift/subsidence, no sea-level rise), they tend to a morphodynamic...abstract 2017

Chavarrias Borras, V. (author), Ottevanger, W. (author), Labeur, R.J. (author), Blom, A. (author)The set of equations used in modelling river morphodynamics needs to be (at least) wellposed to be representative of the real natural phenomenon. As we deal with a time dependent process the solution needs to be wave-like to be well-posed. In other words, the solution must have a domain of dependence and of...abstract 2017

Emmanouil, A. (author), Blom, A. (author), Viparelli, Enrica (author), Frings, R. (author)Sediment management measures are becoming increasingly popular as they are considered sustainable from both economic and environmental point of view. For example, aimed at counteracting river bed degradation, sediment nourishments have been carried out in the German reaches of the Rhine river while a...abstract 2017

Siele, Meles (author), Blom, A. (author), Frings, R. (author), Viparelli, Enrica (author)The main objective of this research is to improve our understanding of the relative contribution of the causes of long-term bed degradation in Rhine and other degrading rivers. That is, the research is intended to quantify past channel adjustment processes, mainly bed degradation and bed surface coarsening...abstract 2017

(author), Torricelli, F. (author)Non-volatile memories—providing the information storage functionality—are crucial circuit components. Solution-processed organic ferroelectric memory diodes are the non-volatile memory candidate for flexible electronics, as witnessed by the industrial demonstration of a 1 kbit reconfigurable memory fabricated on a plastic foil. Further progress,...journal article 2017

Blom, H.A.P.

The forthcoming paradigm shift to Trajectory Based Operations (TBO) requires a similarly effective collaboration between the TBO layer and a tactical layer....conference paper 2017

van Denderen, R. Pepijn (author), Schielen, R.M.J. (author), Blom, A. (author), Hulscher, Suzanne J.M.H. (author), Kleinhans, Maarten G. (author)Side channel construction is a common intervention applied to increase a river's conveyance capacity and to increase its ecological value. Past modelling efforts suggest two mechanisms affecting the morphodynamic change of a side channel: (1) a difference in channel slope between the side channel and the main channel and (2) bend flow just...journal article 2017

Blom, D.S. (author), Birken, Philipp (author), Bijl, H. (author), Kessels, F.J.M. (author), Meister, Andreas (author), van Zuijlen, A.H. (author)In this article, we endeavour to find a fast solver for finite volume discretizations for compressible unsteady viscous flows. Thereby, we concentrate on comparing the efficiency of important classes of time integration schemes, namely time adaptive Rosenbrock, singly diagonally implicit (SDIRK) and explicit first stage singly diagonally...journal article 2016

Stecca, G. (author), Siviglia, Annunziato (author), Blom, A. (author)We present an accurate numerical approximation to the Saint-Venant-Hirano model for mixed-sediment morphodynamics in one space dimension. Our solution procedure originates from the fully-unsteady matrix-vector formulation developed in [54]. The principal part of the problem is solved by an explicit Finite Volume upwind method of the path...journal article 2016

Orru, C. (author), Blom, A. (author), Uijttewaal, W.S.J. (author)Armor breakup and reformation was studied in a laboratory experiment using a trimodal mixture composed of a 1mm sand fraction and two gravel fractions (6 and 10mm). The initial bed was characterized by a stepwise downstream fining pattern (trimodal reach) and a downstream sand reach, and the experiment was conducted under conditions without...journal article 2016

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

In the socio-technical air transportation system these interactions are between human operators, technical systems...book chapter 2016

One of the reasons for poor performance was assigned to project complexity. A combination of lean construction and agile project management are hypothesized as a possible solution to cope with project complexity. In this paper we aim to understand if the...conference paper 2016

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

Here we present new theoretical equations for the graded alluvial river profile that account for the effects of particle abrasion...journal article 2016
