Van Dam, S.S. (author), Bakker, C.A. (author), Van Hal, J.D.M. (author), Keyson, D.V. (author)In an ongoing process, three diverse Home energy management systems (HEMS) have been implemented in the households in the Netherlands. Through a series of questionnaires, interviews, focus groups and usability tests, a wide range of knowledge in being gathered. Because of this broad approach, the insights that are gained are not only limited to...conference paper 2010

Xia, H. (author), Bakker, M.C.M. (author)In the C2CA project, an online sensor system is required to measure and control the quality and homogeneity of demolition concrete continuously. Laser-induced breakdown spectroscopy is a candidate to fulfil the objective in several tasks. Investigated is the ability of LIBS as an online semi-quantitative composition analysis technique. The...conference paper 2012

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

Bakker, M. (author), Vreeburg, J.H.G. (author), Rietveld, L.C. (author), van der Roer, M. (author)An method which compares measured and predicted water demands to detect anomalies, was developed and tested on three data sets of water demand of three years in which and 25 pipe bursts were reported. The method proved to be able to detect bursts where the water loss exceeds 30% of the average water demand in the area. By simultaneously running...conference paper 2012

Bakker, M. (author), Verberk, J.Q.J.C. (author), Palmen, L.J. (author), Sperber, V. (author), Bakker, G. (author)Half of all water supply systems in the Netherlands are controlled by model predictive flow control; the other half are controlled by conventional level based control. The differences between conventional level based control and model predictive control were investigated in experiments at five full scale water supply systems in the first half of...conference paper 2011

Van den Berg, M.R. (author), Bakker, C.A. (author)The paper provides a circular economy framework from a product design perspective with tools to aid product designers in applying circular product design in practice. Design research for circular economy has so far mainly been limited to referring to existing fields of research such as design for disassembly, remanufacturing and recycling. The...conference paper 2015

Bakker, K.J. (author), Bezuijen, A. (author)Ten years have passed since in 1997 for the first time construction of bored tunnels in the Netherlands soft soil was undertaken. Before that date essentially only immersed tunnels and cut-and-cover tunnels were constructed in the Netherlands. The first two bored tunnels were Pilot Projects, the 2nd Heinenoord tunnel and the Botlek Rail tunnel....conference paper 2008

Bakker, M.C.M. (author)Automated optic inspection of concrete aggregates for pollutants (e.g. wood, plastics, gypsum and brick) is required to establish the suitability for reuse in new concrete products. Inspection is more efficient when directly sampling the materials on the conveyor belt instead of feeding them in a sampled stream to the sensor system. However,...conference paper 2017

Sanaee, S.A. (author), Bakker, M.C.M. (author)Ultrasound imaging techniques are proposed for measuring the shape and thickness of immersed waste particles (10-20 mm size) using a linear sensor array from a fixed position. For these purposes both the front and back surface of a particle needs to be reconstructed. Raw ultrasound pulse-echo and plane wave datasets and different imaging...conference paper 2012

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
