Brink, E. (author), Gerber, M. (author), De Boer, A. (author), Van der Geest, M. (author), Zeilstra, D. (author)Starter/generator units based on PM machines are generally not considered due to their inherent safety risks. This technology can, however, prove advantageous for aerospace applications where mass, volume, efficiency and low maintenance costs play a significant role. A safety analysis is performed in order to identify the safety and mitigation...conference paper 2015

(author)To assess the impact of atmospheric aerosols on health, climate, and air traffic, aerosol properties must be measured with fine spatial and temporal sampling. This can be achieved by actively involving citizens and the technology they own to form an atmospheric measurement network. We establish this new measurement strategy by developing and...journal article 2014

Lantsoght, E.O.L. (author), Van der Veen, C. (author), De Boer, A. (author)The shear problem is typically studied by testing small, heavily reinforced, slender beams subjected to concentrated loads, resulting in a beam shear failure, or by testing slab-column connections, resulting in a punching shear failure. Slabs subjected to concentrated loads close to supports, as occurring when truck loads are placed on slab...conference paper 2014

Lantsoght, E.O.L. (author), Van der Veen, C. (author), De Boer, A. (author)For an initial design or assessment of a reinforced concrete solid slab bridge, spreadsheet-based or hand calculations are typically used. The shear stress is compared to the shear capacity as prescribed by the code. The distributed loads result in a uniform shear stress at the support. Concentrated loads are less straightforward to take into...conference paper 2014

(author)Silicon optical microring resonators (MRRs) are sensitive devices that can be used for biosensing. We present a novel biosensing platform based on the application of polyelectrolyte (PE) layers on such MRRs. The top PE layer was covalently labeled with biotin to ensure binding sites for antibodies via a streptavidin-biotin binding scheme....journal article 2014

Scheel, F. (author), De Boer, W.P. (author), Brinkman, R. (author), Luijendijk, A.P. (author), Ranasinghe, R.W.M.R.J.B. (author)A variety of uncertainty sources are inherent in process-based morphodynamic modelling applications. There is an increasing demand for the quantification of these uncertainties. This contribution introduces a probabilistic-morphodynamic (PM) modelling framework that enables this quantification. The PM modelling framework provides a systematic...conference paper 2014

(author)The selective epitaxial growth of Ge-on-Si followed by in-situ deposition of a nm-thin Ga/B layer stack (PureGaB) has previously been shown to be a robust CMOS-compatible process for fabrication of Ge-on-Si photodiodes. In this paper, strategies to improve the control and reproducibility of PureGaB Ge-on-Si photodiode fabrication by reducing the...journal article 2014

Amir, S. (author), Van der Veen, C. (author), Walraven, J.C. (author), De Boer, A. (author)The research subject of this paper is the bearing capacity of transversely prestressed concrete bridge decks between concrete girders under concentrated loads. Experiments on a 1:2 scale model of this bridge were carried out in the laboratory and a 3D nonlinear finite element model was developed in the FEA software package DIANA to study the...conference paper 2014

Amir, S. (author), Van der Veen, C. (author), Walraven, J.C. (author), De Boer, A. (author)In the Netherlands, most of the bridges were built more than 50 years ago and it is essential for designers to find out if these bridges are safe for modern traffic especially in shear since that was not considered in design recommendations before 1976. Detailed experiments have been carried out in the laboratory to investigate punching shear...conference paper 2014

Lantsoght, E.O.L. (author), Van der Veen, C. (author), Walraven, J.C. (author), De Boer, A. (author)The combination of increased live loads and a more conservative shear capacity in the recently implemented Eurocodes, resulted in a large number of existing solid slab bridges in the Netherlands being shear-critical upon assessment. However, an enhancement of the shear capacity can occur in slabs under concentrated wheel loads due to transverse...conference paper 2013

Mohammadi, V. (author), De Boer, W.B. (author), Scholtes, T.L.M. (author), Nanver, L.K. (author)The so-called local-loading effect is studied for pure boron (PureB) depositions from B2H6 in a chemical-vapor deposition (CVD) reactor. This effect occurs because the boron is not deposited on oxide and this increases the deposition rate (DR) of boron in open Si areas in the oxide. Experiments are performed for wide range of local-oxide ratio ...journal article 2012
