Baumann, M.M. (author), van Gijzen, M.B. (author)In this paper we present a comparison study of three different frameworks of iterative Krylov methods that we have recently developed for the simultaneous numerical solution of frequency-domain wave propagation problems when multiple wave frequencies are present. The three approaches have in common that they require the application of a...journal article 2018

Gandini, E. (author), Tamminen, Aleksi (author), Luukanen, Arttu (author), Llombart, Nuria (author)A wide field of view (FOV) inversely magnified dual-lens system for submillimeter wavelength imagers is presented in this paper. The antenna is designed for near-field focusing, at a range of 2.1 m from the primary aperture and to work in the frequency range from 200 to 600 GHz. The half-power beamwidth (HPBW) is 0.27° (1 cm in the image...journal article 2018

Isufi, E. (author), Mahabir, Ashvant S.U. (author), Leus, G.J.T. (author)This letter investigates methods to detect graph topological changes without making any assumption on the nature of the change itself. To accomplish this, we merge recently developed tools in graph signal processing with matched subspace detection theory and propose two blind topology change detectors. The first detector exploits the prior...journal article 2018

Prisacaru, Alexandru (author), Palczynska, Alicja (author), Theissler, Andreas (author), Gromala, Przemyslaw (author), Han, Bongtae (author), Zhang, Kouchi (author)Recent advancements in automotive technologies, most notably autonomous driving, demand electronic systems much more complex than those realized in the past. The automotive industry has been forced to adopt advanced consumer electronics to satisfy the demand, and thus it becomes more challenging to assess system reliability while adopting the...journal article 2018

Giuditta, E. (author), Coenders-Gerrits, Miriam (author), Bogaard, T.A. (author), Wenninger, J.W. (author), Greco, R. (author), Rutigliano, F. A. (author)Wildfires are a growing concern in the Mediterranean area. Prescribed burning (PB) is often used to reduce fire risk, through fine fuel reduction. However, the monitoring of PB effects on ecosystem processes is mandatory before its spread. This study aims to assess hydrological effects of PB on the topsoil by controlled laboratory experiments...journal article 2018

Eker, S. (author), Kwakkel, J.H. (author)Many-Objective Robust Decision Making (MORDM) is a prominent model-based approach for dealing with deep uncertainty. MORDM has four phases: a systems analytical problem formulation, a search phase to generate candidate solutions, a trade-off analysis where different strategies are compared across many objectives, and a scenario discovery...journal article 2018

(author)For absorption refrigeration, it has been shown that ionic liquids have the potential to replace conventional working pairs. Due to the huge number of possibilities, conducting lab experiments to find the optimal ionic liquid is infeasible. Here, we provide a proof-of-principle study of an alternative computational approach. The required...journal article 2018

Wijdeveld, A.J. (author), Schipper, C. A. (author), Heimovaara, T.J. (author)In this study the spatial distribution of dissolved metals in surface water is studied at nine locations in Lake Ketelmeer (the Netherlands). The measured dissolved metal concentrations are combined with the local water quality parameters for salinity, pH, alkalinity and DOC to calculate a FIAM Free Ion Activity Model (FIAM) and the Biotic...journal article 2018

Zhang, H. (author), Šavija, B. (author), Schlangen, E. (author)The aim of this paper is to investigate the fracture performance of cement paste at micro scale by both experimental and numerical methods. Micro cubic specimens with length of 100 µm were fabricated by precision cutting, grinding and micro-dicing, and tested by splitting with a wedge tip mounted on a nano-indenter. A nominal splitting...journal article 2018

(author), Marin, F. (author)According to quantum mechanics, if we keep observing a continuous variable we generally disturb its evolution. For a class of observables, however, it is possible to implement a so-called quantum nondemolition measurement: by confining the perturbation to the conjugate variable, the observable is estimated with arbitrary accuracy, or prepared...journal article 2018

Molecular simulation of vapor-liquid equilibria using the Wolf method for electrostatic interactionsHens, R. (author), Vlugt, T.J.H. (author)The applicability of the Wolf method for calculating electrostatic interactions is verified for simulating vapor-liquid equilibria of hydrogen sulfide, methanol, and carbon dioxide. Densities, chemical potentials, and critical properties are obtained with Monte Carlo simulations using the Continuous Fractional Component version of the Gibbs...journal article 2018

Transport Demand Management Policy Integration in Chinese Cities: A Proposed Analysis of Its EffectsYang, W. (author), Veeneman, Wijnand (author), de Jong, W.M. (author)Transport demand management (TDM) measures are widely regarded as essential tools to deal with traffic issues. Their effectiveness has been under scrutiny. Packaging of TDM measures has recently received much attention from researchers and governments because it can achieve more complex policy goals and resolve the negative effects of single TDM...journal article 2018
