van Damme, M. (author), Visser, P.J. (author)Deriving the bed shear stresses from hydrodynamic models in breach models is challenging due to the continuous changing hydraulic head over the breach in combination with horizontal and vertical flow contractions, and the continuous rapidly changing breach geometry. Three stages can be distinguished in breach flows. Stage 1 initiates when the...conference paper 2015

van Deursen, A. (author), Visser, Eelco (author), Warmer, J (author)Software systems need to evolve, and systems built using model-driven approaches are no exception. What complicates model-driven engineering is that it requires multiple dimensions of evolution. In regular evolution, the model- ing language is used to make the changes. In meta-model evolution, changes are required to the modeling notation. In...conference paper 2007

Konat, G.D.P. (author), Erdweg, S.T. (author), Visser, Eelco (author)It is common practice to bootstrap compilers of programming languages. By using the compiled language to implement the compiler, compiler developers can code in their own high-level language and gain a large-scale test case. In this paper, we investigate bootstrapping of compiler-compilers as they occur in language workbenches. Language...conference paper 2016

Herrema, Floris Friso (author), Treve, V (author), Curran, R. (author), Visser, H.G. (author)currently, at many airports, the runway throughput is the limiting factor for the overall capacity. Among the most important constraining parameters is the separation minima expressed in distance. On the top of these minima, the difference of the leader and follower aircraft speed profiles imposes to consider buffer to cope with compression...conference paper 2016

Visser, H.G. (author), Santos, Bruno F. (author), Verhagen, C.M.A. (author)This paper describes the development of an optimization-based cooperative planning system for the efficient routing and scheduling of flight formations. This study considers the use of formation flight as a means to reduce the overall fuel consumption of civil aviation in long-haul operations. It elaborates on the operational implementation of...conference paper 2016

Verbeek, R.J.D. (author), Visser, H.G. (author)The Single European Sky is being introduced to improve the efficiency of flight and traffic operations by reforming the air traffic management system. Despite all of these technical advances, airlines choose detours to avoid high route charges. This mechanism is intensified when fuel prices are low. The single unit rate method has been proposed...conference paper 2016

(author)Thermal impedance spectroscopy has been investigated as a non-destructive technique to determine the composition of ternary mixtures of biofuels. The principle of the thermal conductivity detector has been extended for measuring both the thermal conductivity and the thermal capacity of biofuel in the range between 1 to 100 Hz, using an AC...conference paper 2017

Visser, T. (author), de Visser, C.C. (author), van Kampen, E. (author)In recent research efforts the multivariate simplex spline has shown great promise in system identification applications. It has high approximation power, while its linearity in the parameters allows for computationally efficient estimation of the coefficients. In this paper the multivariate simplotope spline is derived from this spline, and...conference paper 2016

Distribution centres (DCs) are important to perform logistics activities. In 2015 the demand for logistics real estate has been particularly high compared to previous years. To facilitate the logistics sector and to develop sustainable spatial policies – that for example reduce...conference paper 2016

van Veldhuizen, B.N. (author), van Biert, L. (author), Visser, K. (author), Hopman, J.J. (author)To continue its operations, the marine industry needs to comply with emission regulations. Solid Oxide Fuel Cells (SOFCs) are considered a promising solution, since it can generate energy athigh efficiency and low NOX, SOX and particulate matter emissions. Another advantage of SOFCsis fuel flexibility, meaning several fuels can be applied in...conference paper 2022

Green and circular produced hydrogen as a maritime fuel in fuel cell systems offers a great solution for these concerns. A fuel cell system has a zero emission performance, solid state silent...conference paper 2022
