(author)Recent developments in the concept of UAS operations in urban areas have led to risk concerns of UAS collision with human. To better understand this risk, head and neck injuries due to UAS collisions have been investigated by different research teams using crash dummies. Because of the limitations in biofidelity of a crash dummy, head injury...conference paper 2019

Sun, Junzi (author), Blom, H.A.P. (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)This paper focuses on estimating aircraft mass and thrust setting using a recursive Bayesian method called particle filtering. The method is based on a nonlinear state-space system derived from aircraft point-mass performance models. Using solely ADS-B and Mode-S data, flight states such as position, velocity, and wind speed are collected and...conference paper 2018

Rattanagraikanakorn, B. (author), Sharpanskykh, Alexei (author), Schuurman, M.J. (author), Gransden, D.I. (author), Blom, H.A.P. (author), de Wagter, C. (author)UAS will be integrated into the airspace in the near future, but the risk of UAS collision is not well understood which hampers the development of adequate regulations and standards. As risk has two constituents: frequency and consequence, collision risk analysis of UAS operations in future UTM asks for a quantitative assessment of various...conference paper 2018

Rheza Rahadian, Rheza (author), van der Woude, Sallo (author), Wilschut, D. (author), Blom, C.B.M. (author), Broere, W. (author)During inspections of several immersed tunnels in the Netherlands, damage of immersion joints has been observed. In some cases the Gina seal has moved inwards from its original location, and in other cases a permanent elongation of the entire tunnel structure has been measured. For both cases it has been hypothesised that a seasonal expansion...conference paper 2018

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

Jalali Sohi, A. (author), Hertogh, M.J.C.M. (author), Bosch-Rekveldt, M.G.C. (author), Blom, R. (author)Still, projects in the construction sector are delivered with time delays and cost overruns. 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

Orru, C. (author), Chavarrias Borras, V. (author), Ferrara, V. (author), Stecca, G. (author), Blom, A. (author)A flume experiment was conducted to examine the evolution of a sand-gravel reach under a lack of sediment supply. A bed composed of a bimodal sediment mixture was installed with a uniform slope and an gradual fining pattern. At the upstream end of the flume the initial bed consisted of 100% gravel, which decreased stepwise (10% steps) in...conference paper 2015

Fernandes, O. (author), Blom, D.S. (author), Frey, S. (author), Van Zuijlen, A.H. (author), Bijl, H. (author), Ertl, T. (author)We present an integrated in-situ visualization approach for partitioned multi-physics simulation of fluid-structure interaction. The simulation itself is treated as a black box and only the information at the fluid-structure interface is considered, and communicated between the fluid and solid solvers with a separate coupling tool. The...conference paper 2015

Blom, D.S. (author), Krupp, V. (author), Van Zuijlen, A.H. (author), Klimach, H. (author), Roller, S. (author), Bijl, H. (author)Multi-physics simulations, such as fluid-structure-acoustics interaction (FSA), require a high performance computing environment in order to perform the simulation in a reasonable amount of computation time. Currently used coupling methods use a staggered execution of the fluid and solid solver [6], which leads to inherent load imbalances. In ...conference paper 2015

Blom, D.S. (author), Van Zuylen, A.H. (author), Bijl, H. (author)Strongly coupled partitioned fluid-structure interaction problems require multiple coupling iterations per time step. The fluid domain and the structure domain are solved multiple times in each time step such that the kinematic and dynamic interface conditions on the fluid-structure interface are satisfied. Quasi-Newton methods have been...conference paper 2014

Walhout, W. (author), Wever, R. (author), Blom, E. (author), Addink-Dölle, L. (author), Tempelman, E. (author)Many entrepreneurial businesses have attempted to create value based on the residual material streams of third parties. Based on ‘waste’ materials they designed products, around which they built their company. Such activities have the potential to yield sustainable products. Many of such companies remain in the more artistic domain, with...conference paper 2013
