Sauerwein, M. (author), Zlopasa, J. (author), Doubrovski, E.L. (author), Bakker, C.A. (author), Balkenende, R. (author)The circular economy requires high-value material recovery to enable multiple product lifecycles. This implies the need for additive manufacturing to focus on the development and use of low-impact materials that, after product use, can be reconstituted to their original properties in terms of printability and functionality. We therefore...journal article 2020

Sauerwein, M. (author), Doubrovski, E.L. (author), Balkenende, R. (author), Bakker, C.A. (author)Additive manufacturing, also known as 3D printing, is acknowledged for its potential to support sustainable design. In this paper, we explore whether the opportunities that additive manufacturing offers for sustainable design are also useful when designing for a circular economy, and to what extent additive manufacturing can support design...journal article 2019

Bakker, M. (author)A new analytic solution is presented for tidal propagation in multilayer coastal aquifers consisting of an arbitrary number of layers. The solution is derived using matrix calculus and may be applied to simulate tidal propagation in systems where aquifer layers are separated by leaky layers of low permeability or in stratified aquifers. The head...journal article 2019

Obergfell, C.C.A. (author), Bakker, M. (author), Maas, C. (author)A new method is presented to estimate average diffuse aquifer recharge of water table aquifers in temperate climates using time series analysis of water table level fluctuations. An accurate estimate of the recharge caused by rainfall requires an accurate estimate of the influence of evaporation. In temperate climates, evaporation imprints a...journal article 2019

Obergfell, C.C.A. (author), Bakker, M. (author), Maas, C. (author)Time series analysis is applied to identify and analyze a transition in the groundwater regime in the aquifer below the sand ridge of Salland in the Netherlands, where groundwater regime refers to the range of head variations throughout the seasons. Standard time series analysis revealed a discrepancy between modeled and observed heads in...journal article 2019

Klamer, Pim (author), Gruis, V.H. (author), Bakker, Cok (author)Purpose: Information verification is an important factor in commercial valuation practice. Valuers use their professional autonomy to decide on the level of verification required, thereby creating an opportunity for client-related judgement bias in valuation. The purpose of this paper is to assess the manifestation of client attachment risks...journal article 2019

van Altena, V.P. (author), Krans, Jan (author), Bakker, Henk (author), Dukai, B. (author), Stoter, J.E. (author)Before the interpretation of any text can start, the original wording of the text itself must be critically established. Conventionally, this is done following qualitative criteria. This article, however, explores the application of spatial analyses to New Testament textual criticism by demonstrating how the Levenshtein edit distance could be...journal article 2019

Bakker, R.R. (author), Barnhoorn, A. (author)We study the potential formation damage effects due to radial jet drilling on Bentheim sandstone, a homogeneous sandstone that is well established in terms of mechanical properties and widely used as reservoir analogue. We quantify how properties degrade with distance from a jetted hole on μm scale (porosity) and cm scale (compressive, tensile...journal article 2019

des Tombe, B.F. (author), Bakker, M. (author), Schaars, Frans (author), van der Made, Kees Jan (author)An approach is presented to determine the seasonal variations in travel time in a bank filtration system using a passive heat tracer test. The temperature in the aquifer varies seasonally because of temperature variations of the infiltrating surface water and at the soil surface. Temperature was measured with distributed temperature sensing...journal article 2018

Glynis, K.G. (author), Kapelan, Z. (author), Bakker, Martijn (author), Taormina, R. (author)Researchers and engineers employ machine learning (ML) tools to detect pipe bursts and prevent significant non-revenue water losses in water distribution systems (WDS). Nonetheless, many approaches developed so far consider a fixed number of sensors, which requires the ML model redevelopment and collection of sufficient data with the new...journal article 2023

van der Zwaag, Marco (author), Wang, T. (author), Bakker, H.L.M. (author), van Nederveen, G.A. (author), Schuurman, A.C.B. (author), Bosma, Douwe (author)Facing circular transition challenges, building circularity should be evaluated in the early design phase to reduce the risks of circular and environmental performance problems found in later project phases. However, due to the current design workflow, such practice is hindered because there is not enough information to evaluate building...journal article 2023

Hartley, Kris (author), Schülzchen, S. (author), Bakker, C.A. (author), Kirchherr, J.W. (author)Transitioning from the ‘take-make-dispose’ linear production system to a circular economy can strengthen sustainability, and governments play a vital role. Recent scholarship has investigated policies for circular economy transition, but few studies take a perspective on circularity reform that spans geographies, industries, and product life...journal article 2023

Brakenhoff, Davíd A. (author), Vonk, M.A. (author), Collenteur, Raoul A. (author), Van Baar, Marco (author), Bakker, M. (author)In 2018–2020, meteorological droughts over Northwestern Europe caused severe declines in groundwater heads with significant damage to groundwater-dependent ecosystems and agriculture. The response of the groundwater system to different hydrological stresses is valuable information for decision-makers. In this paper, a reproducible, data-driven...journal article 2022

Keusters, A.C.A.M. (author), Bakker, H.L.M. (author), Houwing, E.J. (author)Purpose: Civil engineering projects around the world have been underperforming for a long time. While the complexity of these projects will continue to increase, there is an urgent need to perform better. Although the integrated design process is critical for project success, the literature lacks studies describing the link to project...journal article 2022

Bos, P. (author), Ritzen, L. (author), van Dam, S.S. (author), Balkenende, R. (author), Bakker, C.A. (author)Replacing fossil-based feedstock with renewable alternatives is a crucial step towards a circular economy. The bio-based plastics currently on the market are predominantly used in single-use applications, with remarkably limited uptake in durable products. This study explores the current state of the art of bio-based plastic use in durable...journal article 2024

Bakker, M. (author), Schaars, Frans (author)Time series analysis is a data-driven approach to analyze time series of heads measured in an observation well. Time series models are commonly much simpler and give much better fits than regular groundwater models. Time series analysis with response functions gives insight into why heads vary, while such insight is difficult to gain with black...journal article 2019
