Vali, M. (author), van Wingerden, J.W. (author), Boersma, S. (author), Petrović, V. (author), Kühn, M. (author)This paper proposes an adjoint-based model predictive control for optimal energy extraction of wind farms. It employs the axial induction factor of wind turbines to influence their aerodynamic interactions through the wake. The performance index is defined here as the total power production of the wind farm over a finite prediction horizon. A...conference paper 2016

Boersma, S. (author), Gebraad, P.M.O. (author), Vali, M. (author), Doekemeijer, B.M. (author), van Wingerden, J.W. (author)In this paper, we present and extend the dynamic medium fidelity control-oriented Wind Farm Simulator (WFSim) model. WFSim resolves flow fields in wind farms in a horizontal, two dimensional plane. It is based on the spatially and temporally discretised two dimensional Navier-Stokes equations and the continuity equation and solves for a...conference paper 2016

Anand, Nilesh (author), van Duin, Ron (author), Tavasszy, Lorant (author)Efficiency of city logistics activities suffers due to conflicting personal preferences and distributed decision making by multiple city logistics stakeholders. This is exacerbated by interdependency of city logistics activities, decision making with limited information and stakeholders’ preference for personal objectives over system efficiency....journal article 2016

Rooij, R.M. (author), Frank, A.I. (author)Planners are often billed as leaders and change agents of the (un)built environment. It is, however, important to recognize that they are in reality only one of many players in a sea of actors involved in shaping future developments and projects. Plans and interventions today are co-created and in fact co-evolve relying as much on the input,...journal article 2016

(author)The growing penetration of distributed energy resources is opening up opportunities for local energy management (LEM) – the coordination of decentralized energy supply, storage, transport, conversion and consumption within a given geographical area. Because European electricity market liberalization concentrates competition at the wholesale...journal article 2016

Stoter, J.E. (author), van Altena, V.P. (author), Post, J.M. (author), Burghardt, D (author), Duchêne, C (author)Producing maps and geo-data at different scales is traditionally one of the main tasks of National (and regional) Mapping Agencies (NMAs). The derivation of low-scale maps (i.e. with less detail) from large-scale maps (with more detail), i.e. generalisation, used to be a manual task of cartographers. With the need for more up-to-date data as...conference paper 2016

Vermaas, P.E. (author)This paper analyses the relation between the precedence of a design method and the justification of the method. A design method is assumed to advance two knowledge claims concerning its domain of application: that it is an effective means for designing and that it is an efficient means for doing so. It is argued that precedence of a method can...journal article 2016

Scholten, D.J. (author), Kunneke, R.W. (author)Energy infrastructures are increasingly perceived as complex, adaptive socio-technical systems. Their design has not kept up; it is still fragmented between an engineering and economic dimension. While economists focus on a market design that addresses potential market failures and imperfections, opportunistic behavior, and social objectives,...journal article 2016

Klaver, T.P.C. (author), Nordlund, K. (author), Morgan, T. W. (author), Westerhof, E. (author), Thijsse, B.J. (author), Van De Sanden, M. C M (author)Results are presented of large-scale Molecular Dynamics simulations of low-energy He bombardment of W nanorods, or so-called 'fuzz' structures. The goal of these simulations is to see if ballistic He penetration through W fuzz offers a more realistic scenario for how He moves through fuzz layers than He diffusion through fuzz nanorods....journal article 2016

Kasraian Moghaddam, D. (author), Maat, C. (author), van Wee, G.P. (author)Long-term, large-scale empirical studies on the simultaneous development of transport infrastructure and the built environment are scarce. This paper provides a long-term study of the development of the railway network and its impact on the built-up area—and vice versa—using the case study of the Randstad in the Netherlands between 1850 and 2010...journal article 2016

Cirillo, P. (author), Taleb, Nassim Nicholas (author)Statistical analyses on actual data depict operational risk as an extremely heavy-tailed phenomenon, able to generate losses so extreme as to suggest the use of infinite-mean models. But no loss can actually destroy more than the entire value of a bank or of a company, and this upper bound should be considered when dealing with tail-risk...journal article 2016
