Quak, Hans (author), van Duin, Ron (author), Hendriks, B. (author)Urban consolidation centres (UCCs) have been discussed over many years in city logistics literature. The amount of successful UCCs in the long-run were, and are, very scarce, though. Little is published on the practical issues and experiences of actually running a UCC and offering UCC-services. In the Netherlands, Binnenstadservice (BSS) runs...conference paper 2019

Riemens, E.H.J. (author), Martinez-Nuevo, Pablo (author), Martinez, Jorge (author), Møller, Martin Bo (author), Hendriks, R.C. (author)Loudspeakers are usually placed in an environment unknown to the loudspeaker designers. Having knowledge on the room acoustic properties, e.g., the location of acoustic reflectors, allows to better reproduce the sound field as intended. Current state-of-the-art methods for room boundary detection using microphone measurements typically focus on...conference paper 2022

Moghaddasi, Hanie (author), Hunyadi, Borbala (author), van der Veen, A.J. (author), de Groot, N.M.S. (author), Hendriks, R.C. (author)Atrial Fibrillation (AF) is the most sustained arrhythmia in the heart. On the surface electrocardiogram (ECG), AF is characterised by the irregular RR intervals and by fibrillatory waves or the absence of a P wave. Since AF is a progressive disease, timely and correct detection is crucial for AF treatment. Detailed insight into the areas of...conference paper 2022

Ibrahim, M.S. (author), Yang, Y. (author), Roosen, M.A. (author), Hendriks, M.A.N. (author)There are a large number of precast girder bridges in the Netherlands that are made continuous utilizing cast in situ layers and cross beams. When controlled by the Eurocode minimum shear reinforcement requirement, the majority of these bridges that were constructed before the 1970s have insufficient amount of transverse reinforcement, which...conference paper 2022

Lu, J. (author), Yang, Y. (author), Hendriks, M.A.N. (author)For reinforced concrete members without shear reinforcement, the shear failure is characterized by the formation of a critical flexural shear crack. Recently experimental observations making use of Digital Image Correlation (DIC) by many researchers suggested the significance of geometric characteristics and kinematic conditions of critical...conference paper 2022

Zhang, F. (author), Yang, Y. (author), Hendriks, M.A.N. (author)Acoustic Emission (AE)-based crack tracking is a promising approach to locate cracks in concrete structures. Different from conventional AE, this approach uses AE activities during crack closure. But, AE activities during crack closure may be influenced by the number of load cycles and loading speed. This may challenge the applicability of AE...conference paper 2021

Esposito, R. (author), Hendriks, M.A.N. (author)The alkali-silica reaction (ASR) is a long-term deterioration process, which produces a hydrophilic and expansive gel causing damage. The ASR acts on concrete as an ageing phenomenon, modifying the material on the basis of its stress state. Focussing on the mechanical degradation of concrete, estimated trends for the mechanical properties in...conference paper 2016

Zhang, J. (author), Hendriks, R.C. (author), Heusdens, R. (author)Randomized gossip (RG) based distributed averaging has been popular for wireless sensor networks (WSNs) in multiple areas. With RG, randomly two adjacent nodes are selected to communicate and exchange information iteratively until consensus is reached. One way to improve the convergence speed of RG is to use greedy gossip with eavesdropping (GGE...conference paper 2016

The first one in The Netherlands, the detection of local defects with different severity levels (squat A, squat B and squat C) is analysed. The second case from the Faurei testing ring in Romania, the detection of...conference paper 2018
