In this thesis, we investigate a sparse basis for ultrasound images, so that we can use sparse regularization in imaging. Actually, there are few previous researches explicitly demonstrating that medical ultrasound images can be sparsified for some dictionary. We consider various orthogonal transforms such as wavelet transforms, cosine...

The robotic volumetric PIV system of the TU Delft is proposed to be used to gather quantitative data in the wakes of footballs. For over a decade now, a new football is introduced every FIFA World Cup. The varying surface characteristics affect the behaviour of the footballs in flight, and so football aerodynamics has become subject to increased...

In order to solve linear system of equations obtained from numerical discretisation fast and accurate, preconditioning on the coefficient matrix is needed. In this thesis research, a preliminary study on preconditioning techniques suitable for Mimetic Spectral Element Method (MSEM) will be presented. The spectral limit change of some important...

With urbanisation, city life is becoming more efficient and artificial. The pace of living is getting faster and the cosiness of slowing down are disappearing. Social warmth among people are decreasing in anonymous cities and spiritual restoration are being pushed away as nature is being pushed out of the expanding cities. This project tries to...

The Pd-based metal membranes have been focused on many studies, because they are the most promising candidates for hydrogen separation. If Pd-based membranes are designed in nanoscale, then the introduced high volume fraction of grain boundaries can act as fast diffusion paths for hydrogen atoms that leading to an increase of hydrogen separation...

This work proposes a method for matching images from different domains in an unsupervised manner, and detecting outlier samples in the target domain at the same time. This matching problem is made difficult by i) the different domain images that are related but under different conditions (e.g. photos of the same location captured in different...

During the last decades, people detection has received great attention in computer vision and pattern recognition because of its various applications. Though there are thousands of papers provide approaches for people detection, most of them focus on datasets from side view. People detection from overhead cameras, as an important situation for...

This project is related to a TU Delft master thesis and is conducted through the Koninklijke Luchtvaart Maatschappij (KLM) Inflight Services department. This department provides all logistics needed to take care of the flights of all cabin crew members, who are currently around 10,000 employees. Due to this large number, scheduling the rosters...

About 65 million global disable population require a wheelchair to keep mobility. However, long-term depending on wheelchairs has intensified the burden on the social economy and brought enormous challenges to wheelchair users health. Physical issues such as body pain, pressure sore, muscle injury and weakness, and cardiopulmonary weakness...

Hong Kong is an immigrant city. Over 30% of population nowadays are immigrant from mainly China mainland, Malaysia, Philippine and UK (CSD, 2017). Sham Shui po is a typical arrival city that had successfully accommodated several generations of immigrants and help them rising to the local city middle class. Sham Shui Po is developed in 1920s. Its...

Norway is mostly known for its natural beauty, fjords and mountains, the amazing Northern Lights and the Midnight Sun - a great intimacy with nature. However, this impression we have of Norway, does not describe the real situation in Oslo.
A total length of approximately 3,400 kilometres of Oslo’s coastline is mostly covered with paved...

Due to the restricted functional collaboration between Hong Kong and Shenzhen Region as well as Pearl River Delta, the functional construction of Hong Kong Region becomes a mono-centric system which leads to a serious unbalanced development between its city centre and its peripheral new towns with great potential. However, the new planning...

Increasing pressure of reducing fuel consumption has led to renewed interests in propeller propulsion devices for their high propulsive efficiency. In a propeller propulsion system, the torque applied to the propeller results in angular momentum in propeller slipstream. This angular momentum is not only a form of energy loss that does not...

The thesis aims to solve partial differential equations numerically using mimetic spectral element method. The method rewrites the PDEs with differential forms so the resulting equations are able to preserve geometrical characteristics in physics. The equation we focus is the Poisson equation, which can be utilized for potential flow problems....

Photographers suffer from many challenging problems when separating and compositing images, such as the color camouflage and unpleasant color bleeding artifacts. To tackle these issues, we present a solution to fore- and background segmentation for images taken from multiple cameras, which introduce the parallax that leads to the foreground...

The prosthetic eye is created to help people who have lost an eye. The eye itself can only improve the appearance but without any optic function. In order to optimize the appearance, a prosthetic eye with a pupil that can dilate and contract according to the light level, just like the natural eye, is desired. The primary goal of this work is to...
