Kongshaug, Simen Sørgaard (author), Larssen, Rolf Magne (author), Hendriks, M.A.N. (author), Kanstad, Terje (author), Markeset, Gro (author)Material modelling, from the micro to the macro level, of concrete affected by alkali–silica reaction (ASR) has been devoted a lot of research. However, the application of the material models in structural analyses of reinforced concrete (RC) structures, showing the structural implications/consequences of ASR, has got little attention in the...journal article 2021

Engen, Morten (author), Hendriks, M.A.N. (author), Monti, Giorgio (author), Allaix, Diego L. (author)When non-linear finite element analyses are used in design of new or assessment of existing concrete structures, one should account for the modelling uncertainty before conclusions are drawn based on the results. The present article describes the basis for how this topic is treated in the draft of fib Model Code 2020. There are two components...journal article 2021

Azizian Amiri, S. (author), van Berckel, Pieter (author), Dankelman, J. (author), Hendriks, B.H.W. (author)Distinguishing the diseased breast tissue from the healthy tissue is a sorely challenging task for the surgeons during breast conserving surgery (BCS) as both tissues own relatively similar visual and haptic characteristics. It has been shown that diffused reflectance spectroscopy (DRS) has the potential to be used as a real-time tumor margin...conference paper 2021

Kolling, B. (author), Abdi, Bahareh (author), Groot, N.M.S. de (author), Hendriks, R.C. (author)Atrial electrograms are often used to gain understanding on the development of atrial fibrillation (AF). Using such electrograms, cardiologists can reconstruct how the depolarization wave-front propagates across the atrium. Knowing the exact moment at which the depolarization wavefront in the tissue reaches each electrode is an important aspect...conference paper 2020

Çalış, M. (author), Heusdens, R. (author), Hendriks, R.C. (author)Average consensus algorithms are used in many distributed systems such as distributed optimization, sensor fusion and the control of dynamic systems. Consensus algorithms converge through an explicit exchange of state variables. In some cases, however, the state variables are confidential. In this paper, a privacy-preserving asynchronous...conference paper 2020

Kotti, Sofia Eirini (author), Heusdens, R. (author), Hendriks, R.C. (author)The use of wireless acoustic sensor networks (WASNs) has received increased attention over the last decade. The advantages of WASNs over stand-alone multi-microphone devices are that the microphone array is not anymore limited by the dimensions of a single device, and that microphones can be placed at arbitrary locations. One of the...conference paper 2020

Sun, M. (author), Isufi, E. (author), de Groot, N.M.S. (author), Hendriks, R.C. (author)Atrial fibrillation is a clinical arrhythmia with multifactorial mechanisms still unresolved. Time-frequency analysis of epicardial electrograms has been investigated to study atrial fibrillation. However, deeper understanding can be achieved by incorporating the spatial dimension. Unfortunately, the physical models describing the spatial...journal article 2020

Gonzales, A. (author), Guo, H. (author), Ortega-Ibáñez, Oscar (author), Petri, Coert (author), van Lier, J.B. (author), de Kreuk, M.K. (author), Hendriks, Alexander (author)Sludge pre-treatments are emerging as part of the disposal process of solid by-products of wastewater purification. One of their benefits is the increase in methane production rate and/or yield, along with higher loading capacities of existing digesters. In this study, we report the performance of a pilot-scale compartmentalized digester (volume...journal article 2020

(author)Background: Electronic health (eHealth) programs are often based on protocols developed for the original face-to-face therapies. However, in practice, therapists and patients may not always follow the original therapy protocols. This form of personalization may also interfere with the intended implementation and effects of eHealth...journal article 2020

Kongshaug, Simen Sørgaard (author), Oseland, Oddbjørn (author), Kanstad, Terje (author), Hendriks, M.A.N. (author), Rodum, Eva (author), Markeset, Gro (author)The alkali silica reaction (ASR) in concrete causes internal localized swelling and micro cracking, which result in expansion and correlated deterioration of the concrete material. The stress state of the concrete is known to affect expansion due to ASR, with an anisotropic stress state giving rise to anisotropic expansion. Similarly, the...journal article 2020

Xia, Y. (author), Langelaar, Matthijs (author), Hendriks, M.A.N. (author)Strut-and-Tie modelling (STM) is a well-known approach to design D-regions in reinforced concrete structures. Because the STM method is based on lower-bound analysis, finding a suitable truss-analogy model is the most important aspect to guarantee good structural and economic performance of a resulting design. Continuum topology optimization ...journal article 2020

Xia, Y. (author), Langelaar, Matthijs (author), Hendriks, M.A.N. (author)Defining a suitable truss model is one of the most important steps of applying the strut-and-tie modeling (STM) method to design D-regions in reinforced concrete (RC) structures. The truss model is a discrete representation of the stress field developed within a region of a concrete element. Topology optimization (TO) methods have been...journal article 2020

(author)Sequentially linear solution procedures provide a robust alternative to their traditional incremental-iterative counterparts for finite element simulation of quasi-brittle materials. Sequentially linear analysis (SLA), one such non-incremental (total) approach, has been extended to non-proportional loading situations in the past few years....review 2020

Quak, Hans (author), van Duin, Ron (author), Hendriks, Birgit (author)Urban consolidation centres (UCCs) have been discussed over many years in the 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 running a UCC and offering UCC-services. In the Netherlands, Binnenstadservice (BSS) has run UCCs...journal article 2020

de Haan, J. (author), Hendriks, Rens (author), Scholz, Michael (author)This paper compares two model-based multilateral price indexes: the time-product dummy (TPD) index and the time dummy hedonic (TDH) index, both estimated by expenditure-share weighted least squares regression. The TPD model can be viewed as the saturated version of the underlying TDH model, and we argue that the regression residuals are ...journal article 2020

Zhang, Jie (author), Chen, Huawei (author), Hendriks, R.C. (author)Multi-microphone speech enhancement methods typically require a reference position with respect to which the target signal is estimated. Often, this reference position is arbitrarily chosen as one of the reference microphones. However, it has been shown that the choice of the reference microphone can have a significant impact on the final...journal article 2020
