Bakker, D.L. (author), Matsuura, D. (author), Takeda, Y (author), Herder, J.L. (author)Continuum manipulators are high degree of freedom structures that can use their increased degrees of freedom to navigate through an environment with obstacles. This type of manipulator is underactuated, which make them promising for adapting to their environments. However, current research is mainly focused on accurate positioning and obstacle...conference paper 2015

Balkenende, R. (author), Bakker, C.A. (author)Sustainability of electronic products until recently mainly focused on improving the energy efficiency. Recently, resource efficiency has become of growing importance. Due to the use of relatively small amounts of many valuable and scarce materials, often intimately mixed, the design of electronic products deserves specific attention. From a...conference paper 2015

Bakker, C.A. (author), Kuijer, L. (author)Mobile devices like smart phones, tablet computers and ultraportable laptops are experiencing rapid worldwide market growth and have relatively short lifespans. Recently, embedded (non-removable) batteries were introduced that cannot be replaced by consumers. This study traces the environmental and social consequences of the introduction of...conference paper 2014

Fakhredin, F. (author), Bakker, C.A. (author), Geraedts, J.M.P. (author)Recycling crosses the fields of resource engineering, metallurgy and materials sciences, and designers cannot be expected to master all these knowledge areas. However, designers need to have access to this knowledge in a simple and clear form, to be able to design products that allow an optimal recovery with minimum quality losses. This is...conference paper 2014

Nilstad Pettersen, I. (author), Bakker, C.A. (author)European ecodesign policy is currently bringing material resource efficiency into focus. This paper explores how and to what extent policy addresses sustainable consumption-related issues, and what the consequences may be for the future role of design in supporting sustainable everyday consumption. How will policy help and hinder designers and...conference paper 2013

Wolters, H.J. (author), Bakker, K.J. (author), De Gijt, J.G. (author)During the last two years, CUR committee 183 has worked on the upgrade of the Dutch Quay Walls handbook (CUR 211), which is to be published in 2013. Two of the main elements that are considered in this new edition are the addition of Finite Element analysis (FEM) as a method for design, comparable to the description in the Handbook Sheet-Pile...conference paper 2013

Bakker, M. (author), Rajewicz, T. (author), Kien, H. (author), Vreeburg, J.H.G. (author), Rietveld, L.C. (author)WTP Gruszczyn supplies drinking water to a part of the city of Pozna?, in the Midwest of Poland. The conventional production flow control and pressure control of the facility was replaced by the advanced control software called OPIR. To assess the differences between conventional and advanced control, production flows and pressures of two...conference paper 2013

For the optimal automatic pressure control of the clear water pumping station, nine pressure measuring points were installed in the distribution network, and an active pressure control model was developed and installed. This model is a hybrid form of...conference paper 2013

Bakker, M. (author)Het drinkwater wordt vanaf de waterzuiveringen naar de onze huizen en bedrijven verpompt via de distributie netwerken. Deze netwerken zijn zeer uitgebreide systemen: naast elke straat en naast veel wegen en door veel weilanden liggen leidingen waardoor het water stroomt. De leeftijd van deze leidingen is divers: in jonge steden of in nieuwe...conference paper 2013

Peck, D.P. (author), Bakker, C.A. (author)A number of recent publications point to the important role of eco-design approaches in risk mitigation for critical materials supply. The core of eco-design is life cycle thinking – usually as some form of Life Cycle Assessment (LCA) approach together with a set of generic guidelines such as checklists, etc. There has however been little...conference paper 2012

Bakker, S. (author), Van der Vooren, A. (author)In this viewpoint paper we challenge the portfolio perspective that envisions a future in which a wide variety of automotive powertrains and fuels will co-exist. We argue that this perspective is driven by normative ideas and rhetoric and that it is more likely that a very limited set of rather similar technologies will survive as successors to...conference paper 2012

Bakker, M. (author), Vreeburg, J.H.G. (author), Van der Roer, M. (author), Sperber, V. (author)An algorithm which compares measured and predicted water demands to detect pipe bursts was developed and tested on three data sets of water demand and reported pipe bursts of three years. The algorithm proved to be able to detect bursts where the water loss exceeds 30% of the average water demand in the area. The accuracy depends on the...conference paper 2012

In order to minimize the damages and the inconvenience for the customers, a software tool was developed to detect anomalies at an early stage, and to support the responsible staff in taking the right decisions to restore...conference paper 2012
