Liu, Xinyuan (author)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...master thesis 2018

Liu, Xin (author)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...master thesis 2018

Liu, Xiaoyezi (author)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...master thesis 2018

Liu, Chang (author)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...master thesis 2018

Liu, Guan-Li (author)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...master thesis 2018

Liu, Zheheng (author)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...master thesis 2019
