Eling, R.P.T. (author), te Wierik, M. (author), van Ostayen, R.A.J. (author), Rixen, D.J. (author)Journal bearings are used to support rotors in a wide range of applications. In order to ensure reliable operation, accurate analyses of these rotor-bearing systems are crucial. Coupled analysis of the rotor and the journal bearing is essential in the case that the rotor is flexible. The accuracy of prediction of the model at hand depends on its...journal article 2016

Islam, Tanvirul (author), Wehner, S.D.C. (author)An efficient implementation of many multiparty protocols for quantum networks requires that all the nodes in the network share a common reference frame. Establishing such a reference frame from scratch is especially challenging in an asynchronous network where network links might have arbitrary delays and the nodes do not share synchronised...journal article 2016

van der Neut, J.R. (author), Wapenaar, C.P.A. (author)Imagine placing a receiver at any location in the earth and recording the response at that location to sources on the surface. In such a world, we could place receivers around our reservoir to better image the reservoir and understand its properties. Realistically, this is not a feasible approach for understanding the subsurface. We have...journal article 2016

Shahmohammadi, M. (author), Babaie, M. (author), Staszewski, R.B. (author)In this paper, we propose a method to reduce a flicker (1/f) noise upconversion in voltage-biased RF oscillators. Excited by a harmonically rich tank current, a typical oscillation voltage waveform is observed to have asymmetric rise and fall times due to even-order current harmonics flowing into the capacitive part, as it presents the lowest...journal article 2016

Righolt, B.W. (author), Kenjeres, S. (author), Kalter, R. (author), Tummers, M.J. (author), Kleijn, C.R. (author)Control of self-sustained jet oscillations in confined cavities is of importance for many industrial applications. It has been shown that the mechanism underlying these oscillations consists of three stages: (i) growth of the oscillation, (ii) amplitude limitation and (iii) delayed destruction of the recirculation zone bounding the jet. It has...journal article 2016

Sedighi, M (author), Hepburn, B.D.P. (author), Thomas, HR (author), Vardon, P.J. (author)Soil atmospheric interactions play an important role within the thermal energy balance and seasonal temperature variations of the ground. This paper presents a formulation for the surface boundary conditions related to interactions between soil and atmosphere. The boundary condition formulated considers heat flow at the soil–atmosphere interface...journal article 2016

Shakibjoo, A.D. (author), Vasegh, N. (author), Hassan HosseinNia, S. (author)In this study a novel structure for time-delay MIMO systems controller design is introduced. In this method decoupled Smith predictor (SP) controller is designed using Internal Model Control structure (IMC). In order to approximate decoupled system, step response model approximation is employed and simulated on MIMO multiple time-delay system....conference paper 2016

Storm, S.T.H. (author)Mainstream climate economics takes global warming seriously, but perplexingly concludes that the optimal economic policy is to almost do nothing about it. This conclusion can be traced to just a few “normative” assumptions, over which there exists fundamental disagreement amongst economists. This paper explores two axes of this disagreement. The...journal article 2016

Honarmand Ebrahimi, K. (author), Bill, Eckhard (author), Hagedoorn, P.L. (author), Hagen, W.R. (author)Ferritin is a nanocage protein made of 24 subunits. Its major role is to manage intracellular concentrations of free Fe(ii) and Fe(iii) ions, which is pivotal for iron homeostasis across all domains of life. This function of the protein is regulated by a conserved di-iron catalytic center and has been the subject of extensive studies over the...journal article 2016

Auping, Willem L. (author), Pruyt, E. (author), Kwakkel, J.H. (author)During the first months, the 2014 outbreak of the Ebola virus (EBOV) in West Africa was characterised by inadequate intervention capacities. In this paper, we investigate (1) the influence of limited but dynamic intervention capacities and their effect on the effective reproduction number, and (2) the effects of proactive versus reactive...journal article 2016

Zhang, L. (author), Slob, E.C. (author), van der Neut, J.R. (author), Staring, M. (author), Wapenaar, C.P.A. (author)We present a one-dimensional lossless scheme to compute an image of a dissipative medium from two single-sided reflection responses. One reflection response is measured at or above the top reflector of a dissipative medium and the other reflection response is computed as if measured at or above the top reflector of a medium with negative...conference paper 2016

de Ridder, Sjoerd (author), van der Neut, J.R. (author), Curtis, A (author), Wapenaar, C.P.A. (author)Recently, a novel method to redatum the wavefield in the sub-surface from a reflection response measured at the surface has gained interest for imaging primaries in the presence of strong internal multiples. A prerequisite for the algorithm is an accurate and correct estimate of the direct-wave Green's function. However, usually we use an...conference paper 2016

Staring, M. (author), van der Neut, J.R. (author), Wapenaar, C.P.A. (author)We present an interferometric interpretation of the iterative Marchenko scheme including both free-surface multiples and internal multiples. Cross-correlations are used to illustrate the combination of causal and acausal events that are essential for the process of multiple removal. The first 4 steps in the scheme are discussed in detail, where...conference paper 2016

Cats, O. (author), Loutos, G (author)Online predictions of bus arrival times have the potential to reduce the uncertainty associated with bus operations. By better anticipating future conditions, online predictions can reduce perceived and actual passenger travel times as well as facilitate more proactive decision making by service providers. Even though considerable research...journal article 2016

Cats, O. (author), Hartl, Maximilian (author)Transit systems are subject to congestion that influences system performance and level of service. The evaluation of measures to relieve congestion requires models that can capture their network effects and passengers' adaptation. In particular, on-board congestion leads to an increase of crowding discomfort and denied boarding and a decrease in...journal article 2016

Cats, O. (author)Investments in transport are increasingly motivated by the need to improve its robustness — the capacity to absorb disturbances with a minimal impact on system performance. Nonetheless, there is lack of knowledge on how to assess and quantify the robustness value of new investments. This study investigates the robustness of alternative public...journal article 2016
