Senior pre-university education (SPE) students experience difficulties applying mathematics to physics. This paper reports the outcome of an online explorative quantitative study of teachers' belief systems about improving transfer of algebraic skills from mathematics into physics, conducted among 503 mathematics and physics teachers working...

The generalized Pareto distribution (GPD) is often used in the statistical analysis of climate extremes. For a sample of independent and identically distributed observations, the parameters of the GPD can be estimated by the maximum likelihood (ML) method. In this paper, we drop the assumption of identically distributed random variables. We...

With a rapid increase in volume and complexity of data sets, there is a need for methods that can extract useful information, for example the relationship between two data sets measured for the same persons. The Partial Least Squares (PLS) method can be used for this dimension reduction task. Within life sciences, results across studies are...

Background: With the exponential growth in available biomedical data, there is a need for data integration methods that can extract information about relationships between the data sets. However, these data sets might have very different characteristics. For interpretable results, data-specific variation needs to be quantified. For this task,...

Floods are a big problem for Jakarta; the capital of Indonesia is subsiding below mean sea level and floods will become more frequent. Flood protection and measures against subsidence are, therefore, of high importance to Jakarta’s government. One of the options they are studying is a great sea wall to regulate the water levels in Jakarta Bay....

In this thesis we study the optimal role assignment in jury voting. Jurors have to decide between two states of nature. Jurors cannot directly observe the state of nature, but only a noisy signal, that is correlated with the true state of nature. Some jurors are better than the other, and higher ability jurors receive signals that more likely...

The quality of magnetic resonance images produced by conventional MRI scanners is guaranteed by the strength and homogeneity of the magnetic field. However, the superconducting magnets required to produce such a field make MRI scanners large and expensive and hence inaccessible to a large number of people in developing countries. Our partners...

We study a (stochastic) parabolic Cauchy problem. We first prove that we have a non-tangential control of the solution of the deterministic parabolic Cauchy problem by the tent space norm of the gradient of the solution. This is done by showing boundedness results for several maximal regularity operators and by developing energy solutions in L^2...

In this thesis we discuss a framework for life-cycle construction. For the construction of life-cycles we use mean-variance optimization. Mean-variance optimization is a portfolio selection method used to find a combination of asset classes that has an optimal risk-return trade-off. We choose the replacement ratio, the pension income as fraction...

For telecommunication businesses it is important to retain as many customers as possible. For this purpose it could be useful to predict which customers have a high potential to stop their subscription. When a customer leaves the company by stopping the subscription, it is called a customer churn. In this thesis customer churn was predicted for...

In optimization, many variants of the Vehicle Routing Problem exists with all sorts of restrictions and characteristics. Heuristics that find near-optimal solutions are known and tested on in the literature, such as heuristics that escape local minima with the use of large neighborhoods. An example is Adaptive Large Neighborhood Search, which...

In this thesis, we take a look at the Asymmetrical Capacitated Vehicle Routing Problem (ACVRP). We will take a look at different possible formulations for the problem and choose one based on the ease of implementation, the computation speed of solving it, and the available relaxations. The problem, and its relaxations, will be modeled and solved...

The purpose of this thesis was to find a (near-)optimal long-haul race strategy for the TU Delft Solar Boat, taking into account practical race conditions and very limited computing time. A race strategy details at what speeds the boat should sail throughout the race, and how long (if at all) it should stop to charge. Various methods have been...

The method Erasmus-iCycle is able to generate a treatment plan for cancer patients, based on the patient's anatomy and a predefined wish list. This wish list contains goals for different organs near the tumour, listed by priority. However, it is not certain that the generated iCycle plan is the best fit for an individual patient, since every...

There has been a lot of research done into traffic on roads and multiple traffic models have been set up for this type of traffic. A subject that has been largely neglected is the traffic on fairways. The research goal set for my graduation project is to define a model that can simulate the traffic on fairways and use this model to optimize the...

In the past few decades telescopes have given us insight into the structures of the observable universe. Current and future astronomical research investigate problems that concern how these structures have been formed and at which rates cosmic structures grow. The redshift of galaxies plays a fundamental role in this research directions, since...

The main idea behind the project was to construct some sort of tool that could help runners, with a TomTom sports watch, in their training, by analysing the data that TomTom has available. Although, still far from reaching the desired goal, this project resulted in many useful insights. In order to construct such a tool training performance and...

The likelihood ratio is a generally accepted measure for the strength of evidence in forensic comparison problems. These problems concern comparisons where it is investigated whether at least two items come from the same source or not, e.g. whether the DNA on the crime scene comes from the suspect or not. The use of likelihood ratios by forensic...

In deze scriptie bestuderen we het aantal kruisingen in een graaf waarbij de knopen in verschillende horizontale levels verdeeld zijn, ook wel het MLCM (Multi-Level Crossing Minimization) probleem genoemd. Vaak wordt een gerichte graaf afgebeeld als een multi-level graaf. We bekijken een voorbeeld van een gerichte graaf: de stamboom van TU Delft...

In this report we applied the marginal structural model and the naive Cox model on a simulated dataset, in order to find differences between these models. The marginal structural model is used to estimate causal effects in case of time-dependent confounding via inverse probability weights. The naive Cox model may produce a bias estimate of the...
