Steam pyrolysis of ethane and naphtha is an important chemical bulk process. It produces ethylene and propylene, which are important base chemicals. In order to be competitive, crackers have to be operated at near optimal conditions. Hence, a simulation program of the process, particularly of the pyrolysis is very helpful. KTI uses and licenses...

For several years the Department of Physical Geography ofthe University of Utrecht has conducted surveys on the river Allier in France. These surveys always took place during periods of low discharge because at high or even moderate discharges measurements are impossible. As information on the flow during a flood is important to understand the...

In the tidal inlets in the Dutch Wadden Sea, the most important sediment types are sand, silt and clay. A distinction between the sediment types is made, because clay particles have cohesive properties. Consequently, the clay particles do not behave as individual particles but tend to stick together. Floes are formed whose size and settling...

HTM is a major role player in the public transportation sector of the Netherlands with its tram and bus services. The company is continually working to improve their infrastructure management policies by considering aspects such as vehicle priorities, driver allocation and vehicle schedules. One obstacle in the way of HTM’s continual improvement...

The use of smart well technology to optimize water flooding introduces a large number of control parameters both in space (well segments) and time. The problem of finding the optimal control parameters to maximize net present value as an objective function can be solved with the aid of a gradient-based optimization method. Using too many...

A method is developed that deals with uncertainties concerning the possible future train services and to what extent different infrastructure alternatives accommodate these train services. A case study is done for the rail line The Hague - Rotterdam. Amongst other methods, a policy analysis approach, a traffic modeling program and a net present...

This project focuses on developing a parallel Navier Stokes simulator capable of modeling single phase dispersion in porous media at the pore scale. Many different factors can contribute to dispersion on a pore scale and this study was limited to fluid flow related factors. The model, including convective motion and diffusive (Fickian) spreading...

The goal of this project is to develop a workforce planning tool. A workforce planning tool is a decision support system (Keen and Sol, 2008) that enables Accenture to make better informed and faster decisions about its future workforce. The workforce planning tool has been developed with a design science approach. This approach is an iterative...

As we move towards an aging population, it is likely that an increasing number of people will require an increasing diversity of implants, but at a lower cost to the society. Also, as computer technology progresses, smaller, more powerful, and less battery intensive implants can be designed. However, present implant design methodology is highly...

An organizations workforce is one of its most important strategic assets. Getting the right workforce at the right time is a very hard job in a constantly changing labor market. To make this job a little bit easier a workforce planning tool has been developed. This tool supports Human Resource Specialists with giving insight into how an...

In this report a model for the ingrowth of a prosthesis in a bone will be formulated and simulated. First an overview is given of all the biological processes that are part of this healing process and what external factors can influence this process. Then a first mathematical model is presented in which the mechanical stimuli (one of the...

As we are moving toward nanometre technology, the variability in the circuit parameters and operating environment (Process, Voltage and Temperature (PVT)) are increasing, causing uncertainty in the circuit performance. Statistical Static Timing Analysis (SSTA) is a category of methodologies to analyse the variations in delay due to PVT...

Airborne gravimetry is an important tool for the geodesy and geophysics communities. Able to provide medium to high-resolution measurements over large areas, it is the link between the low-resolution satellite measurements and expensive terrestrial campaigns, especially in remote areas. To explore the potential of airborne gravimetry, the...

Municipalities in the Netherlands are required to improve the quality of the public services and become more accessible through the internet. Theory on transformation says that to acquire that goal these government organisations must transform their organisational structure to become more process and chain based. A lot of municipalities appear...

A powerful combination of simulation and optimization has been successfully applied to solve real-world decision making problems (Fu et al., 2000; Fu, Glover, & April, 2005). Unfortunately, there are scientific and application problems with this method. Firstly, there is no transparent and formal structure to define the integration between...

In hydraulic engineering it is known that for the evaluation of the performance of a system, a probabilistic approach is preferable to a deterministic one. The essence of such a probabilistic approach is that random variability/uncertainty is explicitly taken into account. In this graduation project, this probabilistic way of looking at a system...

In-situ combustion (ISC) is an enhanced oil recovery process during which air or oxygen-enriched air is injected into a reservoir. The oil in the reservoir reacts with the oxygen and the so-called combustion front is formed and propagates through the reservoir, generating heat and flue gases. During the process, numerous chemical reactions take...

The tourism sector of Norway is one of the sectors that aim for sustainability and is the subject of an ambitious project. With an estimated 5% of the total global CO2 emissions coming from tourism, this is a good sector to examine for improvements in sustainability. The tourism sector in combination with the government started the project...
