Kloosterman, Ritsche A. (author), van der Hoek, J.P. (author), Herder, P.M. (author)A significant challenge for managers of drinking water infrastructures is to make effective strategic decisions for assets with a long lifetime in an uncertain and changing environment. Water resources, which are part of the drinking water infrastructures, have a special position in this decision making process as they operate at the...journal article 2020

Feinberg, A. (author), Ghorbani, Amineh (author), Herder, P.M. (author)In this paper, we investigate the potential of urban commons for building community resilience. We focus on the issue of adaptability to socio-ecological issues, which depends on the social capital built by the local community of practice. We measure this capital through the variables of volunteer involvement, perceived trust, and social...journal article 2020

Wang, N. (author), Verzijlbergh, R.A. (author), Heijnen, P.W. (author), Herder, P.M. (author)Variable Renewable Energy Sources (VRES) are characterized by intensive land-use and variable production. In existing optimization models that minimize the total cost of the energy system, location-specific VRES production profiles are often used to estimate VRES potential, but land-use and land cover aspects have been largely ignored. In this...journal article 2020

Bos, R.A. (author), Nizamis, Kostas (author), Koopman, Bart F.J.M. (author), Herder, J.L. (author), Sartori, Massimo (author), Plettenburg, D.H. (author)With recent improvements in healthcare, individuals with Duchenne muscular dystrophy (DMD) have prolonged life expectancy, and it is therefore vital to preserve their independence. Hand function plays a central role in maintaining independence in daily living. This requires sufficient grip force and the ability to modulate it with no...journal article 2020

Hoevenaars, A.G.L. (author), Krut, S. (author), Herder, J.L. (author)The dynamic performance of a parallel manipulator is often limited by its natural frequencies. These frequencies are a result of the controlled actuator stiffness and the mechanical design. Typically, only the lowest natural frequencies are of interest. However, existing methods to analyze natural frequencies of parallel manipulators with...journal article 2020

Tschiersky, Martin (author), Hekman, Edsko E.G. (author), Brouwer, Dannis M. (author), Herder, J.L. (author), Suzumori, Koichi (author)In this letter we demonstrate a pneumatic bending actuator for upper-limb assistive wearable robots which uses thin McKibben muscles in combination with a flexure strip. The actuator features both active soft actuation and passive gravity support, and in terms of force transmission bridges the gap between the classic rigid type actuators and...journal article 2020

Broeren, F.G.J. (author), van der Wijk, V. (author), Herder, J.L. (author)In this paper, a pseudo-rigid body model is proposed for the analysis of a spatial mechanical metamaterial and its application is demonstrated. Using this model, the post-buckling behavior of the mechanical metamaterial can be determined without the need to consider the whole elastic structure, e.g., using finite-element procedures. This is done...journal article 2020

Brous, P.A. (author), Janssen, M.F.W.H.A. (author), Herder, P.M. (author)The Internet of Things (IoT) might yield many benefits for organizations, but like other technology adoptions may also introduce unforeseen risks and requiring substantial organizational transformations. This paper analyzes IoT adoption by organizations, and identifies IoT benefits and risks. A Big, Open, Linked Data (BOLD) categorization of...review 2019

Heijnen, P.W. (author), Chappin, E.J.L. (author), Herder, P.M. (author)Systems engineers are equipped to design complex networked systems such as infrastructures. A key goal is cost minimization over a vast solution space. However, finding a minimum-cost system while comprehensively satisfying different stakeholders is challenging and lacks proper methodological support. Stakeholders often employ their own...journal article 2019

de Wildt, T.E. (author), Chappin, E.J.L. (author), van de Kaa, G. (author), Herder, P.M. (author), van de Poel, I.R. (author)This paper aims to anticipate social acceptance issues related to the deployment of the smart electricity grid by identifying underlying value conflicts. The smart electricity grid is a key enabler of the energy transition. Its successful deployment is however jeopardized by social acceptance issues, such as concerns related to privacy and...journal article 2019

Gorenstein Dedecca, J. (author), Hakvoort, R.A. (author), Herder, P.M. (author)The deployment of offshore wind and power transmission in the European North Sea is accelerating. Stakeholders advocate regional governance for the European grid expansion, which may evolve into a pan-European governance and is key to developing integrated, hybrid offshore projects. However, such projects are still scarce. We thus analyze the...journal article 2019

Brous, P.A. (author), Janssen, M.F.W.H.A. (author), Herder, P.M. (author)Organizations are increasingly looking to adopt the Internet of Things (IoT) to collect the data required for data-driven decision-making. IoT might yield many benefits for asset management organizations engaged in infrastructure asset management, yet not all organizations are equipped to handle this data. IoT data is collected, stored, and...review 2019

Farhadi Machekposhti, D. (author), Herder, J.L. (author), Tolou, N. (author)Microtransmission mechanisms made of elastic materials present an opportunity for exploring scalable mechanical systems integrated with sophisticated functionalities. This paper shows how the fundamentally limited range of motion in elastic mechanisms can be circumvented to create a frequency doubling functionality analog to angular velocity...journal article 2019

de Jong, J.J. (author), van Dijk, J. (author), Herder, J.L. (author)Fast-moving industrial robots exert large varying reaction forces and moments on their base frame, inducing vibrations, wear and accuracy degeneration. These shaking forces and moments can be eliminated by a specific design of the mass distribution of the robot links, resulting in a dynamically balanced mechanism. Obtaining the conditions for...journal article 2019

Bos, R.A. (author), Plettenburg, D.H. (author), Herder, J.L. (author)While designing a dynamic hand orthosis to assist during activities of daily living, the designer has to know whether a concept will have sufficient grasp performance to support these activities. This is often estimated by measuring the interaction force at the contact interface. However, this requires a prototyping step and limits the...journal article 2019

Broeren, F.G.J. (author), van de Sande, W.W.P.J. (author), van der Wijk, V. (author), Herder, J.L. (author)Dilational structures can change in size without changing their shape. Current dilational designs are only suitable for specific shapes or curvatures and often require parts of the structure to move perpendicular to the dilational surface, thereby occupying part of the enclosed volume. Here, we present a general method for creating dilational...journal article 2019

Park Lee, E.H. (author), Lukszo, Z. (author), Herder, P.M. (author)Fuel cell electric vehicles (FCEVs) have the potential to be used as flexible power plants in future energy systems. To integrate FCEVs through vehicle-to-grid (V2G), agreements are needed between the FCEV owners and the actor that coordinates V2G on behalf of them, usually considered the aggregator. In this paper, we argue that, depending on...journal article 2018
