Collenteur, Raoul A. (author), Bakker, M. (author), Klammler, Gernot (author), Birk, Steffen (author)The estimation of groundwater recharge is of paramount importance to assess the sustainability of groundwater use in aquifers around the world. Estimation of the recharge flux, however, remains notoriously difficult. In this study the application of nonlinear transfer function noise (TFN) models using impulse response functions is explored to...journal article 2021

Pozo Arcos, B. (author), Dangal, S. (author), Bakker, C.A. (author), Faludi, Jeremy (author), Balkenende, R. (author)The process of fault diagnosis is an essential first step when repairing a product: it determines the condition of the parts and identifies the origin of failure. We report on how product users go through the process of fault diagnosis in consumer products and the influence of design features on this process. Two groups of 12 participants were...journal article 2021

(author), Koenderink, G.H. (author), Richter, Ralf P. (author), Ensing, Bernd (author), Bakker, Huib J. (author)The biological functions of natural polyelectrolytes are strongly influenced by the presence of ions, which bind to the polymer chains and thereby modify their properties. Although the biological impact of such modifications is well recognized, a detailed molecular picture of the binding process and of the mechanisms that drive the subsequent...journal article 2021

Sumter, Deborah (author), de Koning, J.I.J.C. (author), Bakker, C.A. (author), Balkenende, R. (author)In a recent study, we identified seven key circular competencies for design: (1) Design for Multiple Use Cycles, (2) Design for Recovery, (3) Circular Impact Assessment, (4) Circular Business Models, (5) Circular User Engagement, (6) Circular Economy Collaboration, and (7) Circular Economy Communication. These were derived from small‐scale...journal article 2021

van Dijkhuizen, M.J. (author), Vrijhoef, R. (author), Bakker, H.L.M. (author)Despite the efforts of governments and firms, the construction industry is trailing other industries in labour productivity. Construction companies are interested in increasing their labour productivity, particularly when demand grows and construction firms cope with labour shortages. Off-site construction has proved to be a favourable policy...conference paper 2021

Jalali Sohi, A. (author), Rikhtegarnezami, M. (author), Bakker, H.L.M. (author), Hertogh, M.J.C.M. (author)Societal challenges such as climate change and inefficiency of energysystems more and more crave for a sustainable environment. Research proved thatrestructuring energy systems into more sustainable forms, called “Energy Transition”, has faced challenges. How to deal with these challenges requires the cocreation between various actors with...conference paper 2021

Bakker, N.J. (author), Åhman, Hanna Nilsson (author), Burgers, Teun (author), Barreau, Nicolas (author), Weeber, A.W. (author), Theelen, Mirjam (author)Partial shading of monolithically interconnected Cu(In,Ga)Se<sub>2</sub> (CIGSe) modules can lead to the formation of reverse bias induced defects. These localized defects permanently reduce the output of the PV module. The formation and propagation mechanisms of these defects is studied. Understanding these mechanisms can help to prevent or...journal article 2020

Poppelaars, F.A. (author), Bakker, C.A. (author), van Engelen, J.M.L. (author)For the transition toward a circular economy, it is essential that products are returned for reuse, refurbishing or recycling. In order to address the lack of literature on the topic from a user perspective, this paper explores how users can be stimulated to return used smartphones. Taking a Research through Design approach, we developed a...journal article 2020

Ökmen, Ö. (author), Bosch-Rekveldt, M.G.C. (author), Bakker, H.L.M. (author)Scheduling of a construction project can be done by using the Critical Path Method (CPM) in case the project is composed of interrelated activities that can be combined through a network. Given uncertainties nowadays and the related need for project schedule adaptations, the question is raised whether and how “traditional” CPM based schedules...conference paper 2020

Chao, C. (author), Bakker, M.C.M. (author), Jommi, C. (author)A simple numerical model was set up to investigate the hydraulic behaviour of a regional dyke to improve understanding of the response under variable atmospheric conditions. The unsaturated hydraulic properties of the dyke body and the relevant foundation layers were calibrated either on the results of laboratory tests or on a national...journal article 2020

van Dam, S.S. (author), Bakker, C.A. (author), Hoogeveen, L.A.J. (author)This paper presents the results of two co-creation sessions with stakeholders in the automotive aftermarket. The sessions were instigated as part of the EU project ReCiPSS to develop a new service to simplify the reverse logistics of automotive cores purposed for remanufacturing. Remanufacturing car parts is a longstanding practice within the...conference paper 2020

Flipsen, Bas (author), Bakker, C.A. (author), de Pauw, I.C. (author)Designing products for the Circular Economy requires closing and slowing of loops by means of repair, reman-ufacturing, refurbishment, parts reuse and/or recycling. Ease of product disassembly facilitates these processes to be more cost-effective, resulting in a better circular strategy fit. In this paper we present the Hotspot Map-ping method....conference paper 2020

Bakker, N.J. (author), Rasia, Alix (author), Assen, Suzanne (author), Aflouat, Basma Ben Said (author), Weeber, A.W. (author), Theelen, Mirjam (author)When a PV module is partially shaded, the shaded solar cells operate in a reverse bias condition. For Cu(In,Ga)Se2 cells this condition can cause defects that irreversibly reduce the output of these cells and the full module. In order to design robust shade-tolerant CIGS modules details need to be known of the conditions at which these...journal article 2020

Giubertoni, Giulia (author), Burla, Federica (author), Bakker, Huib J. (author), Koenderink, G.H. (author)Many biopolymer hydrogels are environmentally responsive because they are held together by physical associations that depend on pH and temperature. Here, we investigate how the pH and temperature responses of the rheology of hyaluronan hydrogels are connected to the underlying molecular interactions. Hyaluronan is an essential structural...journal article 2020

Magnetic resonance imaging (MRI) would be the preferred diagnostic method for infant hydrocephaleus. However, in practice, MRI is seldom used in sub-Saharan Africa due to its high prize, low mobility, and...conference paper 2020

Existing literature, though sparse, has identified a number of circular economy competencies for design. Yet, a coherent overview is lacking. To complement the competencies found...journal article 2020

Pozo Arcos, B. (author), Bakker, C.A. (author), Flipsen, Bas (author), Balkenende, R. (author)Fault diagnosis is the process of identifying and characterising a fault when a failure occurs. It is, therefore, an essential step to take before product-repair. In this study, we ask how conventional users diagnose faults in household appliances and how the design of these appliances facilitates or hampers the process of fault diagnosis.To...journal article 2020
