Lloyd, P.A. (author)This paper takes a narrative seam through the design discipline, attempting to explain how design methodology, one of the three types of Nigel Cross' designerly ways of knowing, has changed over the 40 years of Design Studies. Specifically, the paper identifies the point when a ‘social turn’ in the discipline occurred, allowing more nuanced...journal article 2019

Hoozemans, J.J. (author), de Jong, Rob (author), van der Vlugt, Steven (author), van Straten, J. (author), Elango, Uttam Kumar (author), Al-Ars, Z. (author)This paper presents and evaluates an approach to deploy image and video processing pipelines that are developed frame-oriented on a hardware platform that is stream-oriented, such as an FPGA. First, this calls for a specialized streaming memory hierarchy and accompanying software framework that transparently moves image segments between...journal article 2019

Swuste, P.H.J.J. (author), van Nunen, K. (author), Reniers, G.L.L.M.E. (author), Khakzad, N. (author)Major accidents in Western countries, receiving a lot of media attention in the 1970s, are starting point for research into internal and external domino effects in the chemical and petrochemical sectors and clusters. Initially, these reports are published by government institutions and government-related research centres. With the upcoming...review 2019

Prasse, B. (author), Van Mieghem, P.F.A. (author)The SIS dynamics of the spread of a virus crucially depend on both the network topology and the spreading parameters. Since neither the topology nor the spreading parameters are known for the majority of applications, they have to be inferred from observations of the viral spread. We propose an inference method for both topology and spreading...journal article 2019

van der Wegen, M. (author), Roelvink, D. (author), Jaffe, B. E. (author)Intertidal mudflats are morphodynamic features present in many estuaries worldwide. Often located between vegetated shores and deep channels they comprise valuable ecosystems and serve to protect the hinterland by attenuating waves. Although mudflats are persistently present on yearly to decadal time scales, little is known on their...journal article 2019

Hartel, P.H. (author), Homoliak, I. (author), Reijsbergen, Daniël (author)Since it takes time and effort to put a new product or service on the market, one would like to predict whether it will be a success. In general this is not possible, but it is possible to follow best practices in order to maximize the chance of success. A smart contract is intended to encode business logic and is therefore at the heart of...journal article 2019

Yu, J. (author), Du Nguyen, H.A. (author), Abu Lebdeh, M.F.M. (author), Taouil, M. (author), Hamdioui, S. (author)Automata Processor (AP) is a special implementation of non-deterministic finite automata that performs pattern matching by exploring parallel state transitions. The implementation typically contains a hierarchical switching network, causing long latency. This paper proposes a methodology to split such a hierarchical switching network into...conference paper 2019

Miri Rostami, Seyyed Reza (author), Mozaffarzadeh, M. (author), Hariri, Ali (author), Jokerst, Jesse V. (author), Ghaffari-Miab, Mohsen (author)Double-stage delay-multiply-and-sum (DS-DMAS) is one of the algorithms proposed for photoacoustic image reconstruction where a linear-array transducer is used to detect signals. This algorithm provides a higher contrast image in comparison with the conventional delay-multiply-and-sum (DMAS) and delay-and-sum (DAS), but it imposes a high...conference paper 2019

Zhang, D. (author), Tenpierik, M.J. (author), Bluyssen, P.M. (author)The acoustic conditions of classrooms received a lot of attention in the last decades because of its important role in school children's comfort and performance. In a previous field study of 54 classrooms from 21 schools in the Netherlands, more than 85% of the 1145 primary school children reported that they were bothered by noise in the...journal article 2019

Chen, Z. (author), Qu, Ying xia (author), Zeilstra, Christiaan (author), Van Der Stel, Jan (author), Sietsma, J. (author), Yang, Y. (author)HIsarna is a promising ironmaking technology to reduce CO <sub>2</sub> emission. Information of phase transformation is essential for reaction analysis of the cyclone reactor of the HIsarna process. In addition, data of density and volume of the ore particles are necessary for estimation of the residence time of the particles in the cyclone...journal article 2019

Wan, Xiaoyun (author), Ran, J. (author)The aim of this paper is to present an alternative method that can be used to improve existing gravity field models via the application of gradient data from Gravity field and Ocean Circulation Explorer (GOCE). First, the proposed algorithm used to construct the observation equation is presented. Then methods for noise processing in both time...journal article 2019

(author)Synthetic-aperture (SA) imaging is a popular method to visualize the reflectivity of an object from ultrasonic reflections. The method yields an image of the (volume) contrast in acoustic impedance with respect to the embedding. Typically, constant mass density is assumed in the underlying derivation. Due to the band-limited nature of the...journal article 2019

Meijer, D.W.J. (author), Scholten, L. (author), Clemens, F.H.L.R. (author), Knobbe, Arno (author)Sewer pipes are commonly inspected in situ with CCTV equipment. The CCTV footage is then reviewed by human operators in order to classify defects in the pipes and make a recommendation on possible interventions. This process is both labor-intensive and error-prone. Other researchers have suggested machine learning techniques to (partially)...journal article 2019

Coutino, Mario (author), Isufi, E. (author), Leus, G.J.T. (author)Graph filters are one of the core tools in graph signal processing. A central aspect of them is their direct distributed implementation. However, the filtering performance is often traded with distributed communication and computational savings. To improve this tradeoff, this paper generalizes state-of-the-art distributed graph filters to...journal article 2019

Scharenborg, O.E. (author), van Os, Marjolein (author)There is ample evidence that recognising words in a non-native language is more difficult than in a native language, even for those with a high proficiency in the non-native language involved, and particularly in the presence of background noise. Why is this the case? To answer this question, this paper provides a systematic review of the...review 2019
