Dynamica van Kanaalsortering in Cellulaire Netwerken

Willems, R.H.J. (author)

Kanaalsortering is een “langzame” kanaaltoewijzingsmethode die kanalen afhankelijk van de verkeershoeveelheid aan de cellen toewijst. Dit afstudeerverslag bespreekt de dynamica van het kanaalsorteringsalgoritme. Er is een netwerk gesimuleerd dat bestaat uit twee cellen en waarin het verkeer varieert in de tijd. Het kanaalsorteringsalgoritme is...

Developing a diagnostic assessment tool to evaluate damage in buildings

Willems, Rick (author)

Mining activities at the Groningen gas field are causing earthquakes which result in building damage. This has started a discussion on what type of damage is caused by earthquakes. These discussions are typical in the forensic engineering field, especially in complex cases. The problem is the lack of regulations, in terms of standardizations and...

Analysis of Skill Development in Manual Ramp Tracking Tasks: Using a Feedforward Pilot Model

Willems, M.E. (author)

A study is performed analyzing the behavioral adaptation of pilots in skill based ramp tracking tasks performed with pursuit display. From data analyses of previous ramp tracking experiments an indication is found that pilots who repeatedly perform the same ramp tracking task show a high level of adaptation to characteristics of the control task...

Coupled modeling of dynamic ice-structure interaction on offshore wind turbines

Willems, T. (author)

The offshore wind industry is growing at high pace and is already one of the major renewable energy sources in Europe. To support this growth, costs must be further decreased, amongst others by efficiently designing the support structure of the offshore wind turbines (OWT). This requires accurate prediction of environmental loading such as...

Study of the Lower Cretaceous sands in the Van den Bosch Geothermal energy concession

Willems, C.J.L. (author)

Goal of this project was to get a better understanding of the producing formations in the two doublets in the Van den Bosch Geothermal energy concession in Bleiswijk. It can be concluded based on the GR logs in VDB-04, the lithologs, End Of Well reports, a Biostrat log in VDB-04 and the seismic interpretation that the first doublet (VDB-01 & VDB...

Spatiotemporal Gaussian random fields using stochastic partial differential equations

Willems, Joshua (author)

In various scientific disciplines, measurement data is collected across space and over time with the aim of inferring information regarding an underlying stochastic spatiotemporal phenomenon. The high computational costs of current methods render this task intractable for the large datasets typically encountered in spatiotemporal statistics. <br...

The localisation of freight wagons on marshalling yards: Using multiple GPS measurements of stationary freight wagons to determine their location on a marshalling yard

Willems, H.R.S. (author)

Freight is moved by trucks on the road more and more, which is a worrying thing, especially for the environment. A very good alternative to transportation by trucks is transportation by trains. The Dutch government aims to increase the transportation of goods by train from 13% of all transportation to 20% of all transportation, but in reality,...

Data streams in spreadsheets with reactive extensions

Willems, L. (author)

The amount of collected data increases exponentially and this exponential growth comes with a demand to analyze big volumes of data and to process the data fast and in real time. Business analysts have the expertise in the domain of the desired stream processing applications, but often lack the technical skills to create these kind of...

System-based replacement of hydraulic structures: A study to replace the weirs in the river Meuse

Willems, Douwe (author)

For centuries humanity has been engineering the second largest river system in the Netherlands, the river Meuse system. This resulted in improvements for the shipping and water safety functions, but simultaneously has had a negative impact on other functions of the river Meuse system. Nature and water quality, for example, degraded due to the...

De optimale weg: Publiek private samenwerking bij infrastructuur

Willems, E. (author)

In de Leidse agglomeratie en in het gebied ten westen daarvan treedt een aantal uiteenlopende verkeersproblemen op. In algemene zin gaat het vooral om intensief autoverkeer dat op verschillende wegvakken congestie veroorzaakt en de leefbaarheid in de steden en dorpen aantast. De congestie belemmert ook de economische ontwikkeling. Meer in het...

Investigation of the sand losses which occur during construction of a closure dam in a tidal inlet

Willems, J.A. (author)

At the construction of 'Maasvlakte 2' in 2012, two sand closures were constructed. Sand is in most cases the most profiting construction material. The processes and the amount of sand losses which occur during the construction of a closure contain large uncertainties. In order to construct a closure, the production of sand has to be larger than...

Measuring time distribution of engineering test and production code

Willems, W.F.P. (author)

Testing software is an important factor in application development. Without proper testing, software can be unreliable and show failures with drastic consequences. There have been attempts to measure how much time is spent on testing but these methods are not accurate as they depend on incomplete or subjective data. An Eclipse plugin called ...
