Generative adversarial networks (GANs) have shown promising results when applied on partial differential equations and financial time series generation. This thesis investigates if GANs can be used to provide a strong approximation to the solution of stochastic differential equations (SDEs) of the Ito type. Standard GANs are only able to...

The objective of this thesis is to show that warping can be used in a thin-walled beam to create a suitable replacement for a classical differential mechanism. This normally negated deformation of the cross section can be used to create an inverse transmission mechanism, used to create a monolithic and simple alternative to a classic...

Backward stochastic differential equations (BSDE) are known to be a powerful tool in mathematical modeling due to their inherent connection with second-order parabolic partial differential equations (PDE) established by the non-linear Feynman-Kac relations. The fundamental power of BSDEs lies in the fact that with them one does not merely obtain...

This thesis showcases a rather contemporary method of solving a generalized system of stochastic differential equations (SDE's) comparable to the SABR model. The solution is derived from a stochastic-local volatility (SLV) model in which the local volatility (LV) component is kept general. This generality is maintained throughout all derivations...

In the ocean resides a large amount of plastic. This has severe environmental consequences for the oceans. To be able to clean up all this plastic the location of the plastic is needed. A lot of times plastic is cleaned up at the source, but to clean up here this location needs to be known. However, what if the start location is not known and...

In financial and egineering problems, we are often faced with solving Partial-Integro Differential Equations (PIDEs). Rarely we can find an analytic solution in a closed form expression for these PIDEs, hence we turn to numerical schemes to accurately approximate the solution instead. Classically these methods are based on finite difference...

This thesis considers the thin-film equation in partial wetting. The mobility in this equation is given by h<sup>3</sup>+λ<sup>3-n</sup>h<sup>n</sup>, where h is the film height, λ is the slip length and n is the mobility exponent. The partial wetting regime implies the boundary condition dh/dz&gt;0 at the triple junction....

The "FM Chirp Waveform Generator and Detector for Radar" is a Bachelor graduation project with an educational purpose. In this thesis, two modules of the whole system are designed and simulated. In particular, the sawtooth generator and the FM detector. The sawtooth generator is used to generate a linearly increasing signal, which can be used to...

Differential thrust can be used for directional control on distributed electric propulsion aircraft. This thesis presents an assessment of flight dynamics and control of differential thrust aircraft under engine inoperative conditions with minimum control speed. A methodology consisting of an aerodynamic data acquisition module and a non-linear...

The propellantless nature of solar-sail propulsion allows researchers to design completely new sets of orbits unreachable or not-maintainable by means of conventional propulsion. The advantage of this somewhat new type of low-thrust propulsion system becomes more evident for long-duration missions where chemical or electrical rocket engines...

Psychiatric disorders are associated with major societal, personal issues and comprise 13% of the global burden of disease. They are heritable and present a complex pathophysiology, characterized by hundreds of genetic variants which are cumulated together and provoke a specific psychiatric disorder. Although a considerable progress has been...

Currently, the inland shipping industry is not sufficiently incentivised to invest in sustainable technologies in order to reduce their emissions. The industry itself wants to be more sustainable, but there is insufficient financial room to invest in alternative technologies. Besides, public authorities try to achieve a reduction using command...

Reliable and efficient modelling of magnetic hysteresis in inhomogeneous and aniso-tropic media is an important step in developing a state-of-the-art closed-loop degaussing system for naval ships and submarines, to be developed by TNO and to be used by the Royal Netherlands Navy in an updated generation of naval vessels and submarines. Different...

Understanding the permeability of the subsurface is a crucial step to simulate fluid flow in the subsurface. A parameter estimation problem for the flow equations can be solved to find the permeability. The robust identification of material parameters remains a significant challenge. In classical approaches, the non-linear least-squares problem...

Recent years have seen a drastic increase in the number of small satellites launched per year, as these systems weighing less than 1000 kg have become less expensive alternatives to obtaining scientific data compared to satellites weighing multiple tons. A current drawback with these systems is their price to orbit, often reaching over $100k ...

Pulmonary arterial hypertension (PAH) is a complex, progressive disease characterized by an increased mean pulmonary arterial pressure at rest, and is associated with a high rate of mortality due to right ventricular failure as the disease progresses. While numerous animal and cell culture models have been created in an attempt to better...

This work presents a low-noise amplifier (LNA) for ultrasound imaging with built-in continuous time-gain compensation (TGC), which compensates for the time-dependent attenuation of the received echo signal and thus significantly reduces its dynamic range (DR). The proposed design combines the LNA and TGC functions in a single variable-gain...

When data in higher dimensions with a certain constraint on it, say a set of locations on a sphere, is encountered, some classical statistical analysis methods fail, as the data no longer assumes its values in a linear space. In this thesis we consider such datasets and aim to do likelihood-based inference on the center of the data. To model the...

With the growing wealth and economy of a country, there are an increasing amount of small and big businesses. Every company has its own marketing strategy that it uses in order to lure customers away from their competition and increase their sales. Choosing the perfect time to advertise or discount several products is of essence for a company to...

We consider adaptive network models with discrete and continuous state sets obeying dynamical rules that enable application to swarming systems. The 2-state adaptive network contains a supercritical pitchfork bifurcation in the transition between ordered and disordered stationary solutions. We derive an adaptive network model that works on a...
