Bakker, W. (author), Hofland, Bas (author), de Almeida Sousa, E. (author), Oldenziel, G. (author), Overmars, E.F.J. (author)In this paper the development of a high-power pulsed LED line light and its use to apply particle image velocimetry (PIV) during wave impact measurements are described. An electrical circuit that generates high-current pulses is designed and built, which is used to overdrive a number of commercially available LEDs. The limit for this...journal article 2021

Evers, Bernard (author), Gerding, Albert (author), Boer, Theo (author), Heiner-Fokkema, M. Rebecca (author), Jalving, Mathilde (author), Wahl, S.A. (author), Reijngoud, Dirk Jan (author), Bakker, Barbara M. (author)13C-isotope tracing is a frequently employed approach to study metabolic pathway activity. When combined with the subsequent quantification of absolute metabolite concentrations, this enables detailed characterization of the metabolome in biological specimens and facilitates computational time-resolved flux quantification. Classically, a 13C...journal article 2021

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

De Fazio, F. (author), Bakker, C.A. (author), Flipsen, Bas (author), Balkenende, R. (author)Designers and engineers need better tools and methods to create highly repairable products. Design for disassembly and reassembly is an important product related design feature that can enhance repair. In a highly repairable product, the components that fail most often should be easily accessible for repair or replacement. This paper...journal article 2021

Polat, E. (author), van Dam, S.S. (author), Bakker, C.A. (author)The Covid-19 outbreak forced many universities across the world to transition from a traditional or blended format to fully online education. This paper presents a case study on the transition to an online education format for a circular design course. Both quantitative and qualitative data were collected through a survey with 26 students and...journal article 2021

(author), van der Esch, Martin (author)Background: Patients with knee osteoarthritis can adapt their gait to unload the most painful knee joint in order to try to reduce pain and improve physical function. However, these gait adaptations can cause higher loads on the contralateral joints. The aim of the study was to investigate the interlimb differences in knee and hip frontal...journal article 2021

Bakker, Coen (author), Zhang, L. (author), Higginson, Kristie (author), van Keulen, A. (author)Stiffened shells and plates are widely used in engineering. Their performance is highly influenced by the arrangement, or layout, of stiffeners on the base shell or plate and the geometric features, or topology, of these stiffeners. Moreover, modular design is beneficial, since it allows for increased quality control and mass production. In...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

Duijff, R. (author), Bloemendal, Martin (author), Bakker, M. (author)Aquifer thermal energy storage (ATES) is an energy efficient technique to provide heating and cooling to buildings by storage of warm and cold water in aquifers. In regions with large demand for ATES, ATES adoption has lead to congestion problems in aquifers. The recovery of thermal energy stored in aquifers can be increased by reducing the...journal article 2021

(author), Bakker, I.P. (author)We present our short series of interactive animations on directional derivatives and level curves. This visualisation was developed for students of first-year mathematics courses at the Delft University of Technology.

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

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
