Van Oort, N. (author), Sparing, D. (author), Brands, T. (author), Goverde, R.M.P. (author)There is a growing pressure on urban public transport companies and authorities to improve efficiency, stemming from reduced budgets, political expectations and competition between operators. In order to find inefficiencies, bottlenecks and potentials in the public transport service, it is useful to learn from recorded operational data. We first...conference paper 2012

Avramescu, D.I. (author)The number of wireless sensor networks is constantly increasing. In the deployment phase of the WSNs projects it is common for failures to appear. These can be caused by software or hardware faults or by environmental factors. In order to find the source of these problems, the WSN needs to be inspected. Since the deployments of WSN are often...master thesis 2012

Boullenger, B. (author)Seismic Interferometry (SI) with ambient noise is a recently developed method for subsurface imaging that involves cross-correlating ambient noise from passive seismic data to reveal the earth’s reflection response. Based on this technique, TNO aims at developing a methodology for efficient monitoring of CO2 geological sequestration in Carbon...master thesis 2012

Deen, G. (author)We have identified three fundamental monitoring dimensions for the maintenance and evolution of Maritime Safety and Security Systems, which are representing a class of systems that are required to be continuously online. The monitoring dimensions consist of: 'services', 'users' and 'time'. As traces crosscut these dimensions, we are interested...master thesis 2012

Van den Berg, R.L.J. (author)Buildings must be designed to meet horizontal deformation and vibration requirements when loaded by a wind force. These requirements can be governing in the design of the load bearing structure of a high-rise building. The structure can be optimized by describing and analyzing its dynamic behaviour. Information on damping is required to...master thesis 2012

Boufidou, E. (author), Commandeur, T.J.F. (author), Nedkov, S.B. (author), Zlatanova, S. (author)Modern large cities are characterized by a high building concentration, little aeration and lack of green spaces. Such characteristics create an urban climate which is different from the climate outside of cities. An example of an urban climate effect is the so-called Urban Heat Island: cities tend to be warmer than the surrounding rural areas....conference paper 2011

Alhaddad, B.I. (author), Burns, M.C. (author), Roca, J. (author)Urban areas are complicated due to the mix of man-made features and natural features. A higher level of structural information plays an important role in land cover/use classification of urban areas. Additional spatial indicators have to be extracted based on structural analysis in order to understand and identify spatial patterns or the spatial...conference paper 2011

Schilperoort, R.P.S. (author)The wastewater system in the Netherlands comprises approximately 100,000 km of sewer pipes and more than 350 wastewater treatment plants (wwtp). The system collects and treats the majority of domestic and industrial wastewater. A small amount of untreated wastewater, however, is occasionally discharged to rivers and lakes, often resulting in a...doctoral thesis 2011

Strydis, C. (author)HEALTHCARE in the 21st century is changing rapidly. In advanced countries, in particular, healthcare is moving from a public to a more personalized nature. However, the costs of healthcare worldwide are increasing every year. Better use of technology can and should be used to get control of these costs. At the same time, implants have clearly...doctoral thesis 2011

Smith, J. (author)Putting effort into the early project phases in order to prepare optimally for project delivery is labelled Front-End development (FED). For projects, an optimum has to be found where FED is performed in a way that it increases the chance on successful project delivery, without losing cost competiveness. The results of this research can be used...master thesis 2010

Briels, S.A. (author)By recording infrasound signals one is able to listen to the sound of highly energetic events such as volcanoes, meteorites and the supersonic flight of aircraft, even if these occur hundreds of kilometres away. Recordings of infrasound signals are made using infrasound arrays, which can determine the incoming direction of the signals. In this...master thesis 2010

Hiervoor wordt de structurele conditie aan de hand van een vaste beoordelingsmethode vastgelegd. Op basis van deze structurele conditie wordt de veiligheid tegen het schadebrengend effect van golfklappen vastgesteld. In 2007 is een studie [1]...report 2010

Coelho, B. (author), Priest, J. (author), Holscher, P. (author), Powrie, W. (author)Transitions between railway track on embankments or natural ground and fixed structures such as bridges and culverts often require substantial additional maintenance to preserve line, level and ride quality. This extra maintenance not only increases costs but also causes delays. Despite its importance for railway infrastructure owners, the...conference paper 2009

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
