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....

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...

Hydrocephalus is one of the most common abnormalities affecting the nervous system of children around the globe. Especially in developing countries hydrocephalus is a large problem. It is often left untreated resulting in suffering, brain damage, developmental delays and ultimately death. This makes an early detection more opportune than ever....

Google uses the PageRank algorithm to rank the web. The algorithm models the behavior of a random surfer. It follows an outlink or it goes to any page by entering a URL into an address bar. This is also called teleportation. The probability that a surfer teleports to a page is given in the personalization vector. The PageRank algorithm returns a...

In this report, we will try to model a silicon chip with elements, as used in current experiments, with the aim to find a suitable and fast model for the transducer used. The specific question we will try to address is: How well can we model the effects of induced oscillation on other elements on a silicon chip? Induced oscillations can create...

Panel codes are used by the Maritime Reseach Institute Natherlands (MARIN) to compute flows around ships and propellers. These codes are based on Boundary Element Methods (BEM). A known drawback of BEM is that it forms dense linear system of equations that have to be solved. By improving the efficiency of the dense linear solver, the...

The TU Delft Solar Boat is a very efficient boat that sails on solar power. To reduce drag the boat lifts out of the water with the hull and "flies" on two hydrofoils. As a result the boat is likely to fall over and seems to be unstable. To analyse the stability we first made a mathematical model that describes the motion of the boat. Based on...

In seismic tomography, parts of the Earth are reconstructed by the travel times of seismic waves that are measured by seismometers. These tomographic problems can be formulated as a system of linear equations. Unfortunately, most of the time the system is ill-posed, because of ray bending and noise. This problem can not only be found in...

PageRank, a method to rank web pages objectively and mechanically, models a random web surfer. The PageRank problem is most easily solved iteratively, using the power method. In this paper the reordered PageRank algorithms are discussed. These algorithms (proposed by A. N. Langville and C. D. Meyer in "A reordering for the PageRank problem") see...

In this research, a stochastic model for attenuation in Computer Tomography is developed. This model gives rise to the idea of using path dependent variance of the measurements (instead of constant variance) to improve image reconstruction. The distribution of the measurements in this model is determined and a difference with the current...

Google PageRank is an algorithm incorporated by Google to rank websites, using the amount of links a website has as well as the importance of each link. This process can be calculated using the power method. As the amount of websites grows it is essential to speed up this process. Two extrapolation methods, Aitken Extrapolation and Quadratic...

The Induced Dimension Reduction(s) method (or the IDR(s) method) is an example of an iterative method used for solving systems of linear equations. Projection methods are a special type of iterative method. They find an approximate solution in a subspace (the right subspace) by requiring that the residual is orthogonal to another subspace (the...

The oil industry is at the backbone of global economy and, as natural resources are becoming scarce, there is a pressing need for efficient extraction strategies. This has led to the development of reservoir models and simulators, able to predict future field behaviour, when paired with accurate geological information. However, the data obtained...

This thesis approaches the solution of the linearized finite element discretization of the Navier-Stokes operator matrix via the use of Krylov subspace methods preconditioned by SIMPLE-type pre conditioners aided by deflation. It includes an explanation of the theoretical setting of the problem as well as a collection of numerical experiments...

The model-order reduction techniques Proper Orthogonal Decomposition (POD) and Discrete Empirical Interpolation Method (DEIM) have been applied for the optimal control of Burgers' equation. Accuracy and performance of the reduced models have been studied in detail for different values of the viscosity parameter and different sizes of the...

This research investigates iterative methods for solving large and sparse least squares problems, as those encountered in tomography. A widely used method for such systems is the Conjugate Gradients method for Least Squares problems (CGLS), which is derived from the popular Conjugate Gradient method. The Conjugate Residuals method can also be...
