Scale is an important parameter of images. Different objects or image structures (e.g. edges and corners) can appear at different scales and each is meaningful only over a limited range of scales. Multi-scale analysis has been widely used in image processing and computer vision, serving as the basis for many high-level image analysis systems....

The Yellow River is known as the ‘mother river’ of the Chinese people, but is also said to be ‘China's Sorrow’ or the ‘Scourge of the Sons of Han’, because in history multiple major floods have had catastrophic effects on people and land along the 5000 km long river reaching from the Himalaya’s to the Bohai Sea. Three sections can be...

Noise levels due to road traffic have reached intolerable high levels in and around many urban areas all around the world. Because of health reasons and reasons of well- being these noise levels have to be reduced. The noise produced from the interaction between the rolling tyre and road surface is one of the most important contributions in the...

Fatigue characterization of an asphalt mixture is commonly estimated by laboratory fatigue tests. Based on the classical fatigue analysis, fatigue lives obtained from different test devices are not comparable even when they are performed at the same test conditions. It is believed that there are two main reasons causing the difference in fatigue...

Coastal erosion has gained global attention and has been studied for many decades. As a soft sea defence structure, coastal sandy dunes protect coastal zones all over the world, which usually are densely populated areas with tremendous economic value. The coastal zone of the Netherlands, one of the most well-known vulnerable areas to coastal...

Hyperconcentrated flow/flood is a water-driven sediment transport phenomenon, which is characterized by high sediment concentrations between normal sediment-laden flow and debris/mud flow. In a hyperconcentrated flow, strong interactions exist between water flow, sediment, and river bed, which may not only change the flow rheological properties,...

The high growth rate of vehicle ownership and many novel drivers in China determine the special features of Chinese driver behavior. This thesis introduces a comparative study on driver behavior by the analysis of saturation flow at urban intersections, Driver Behavior Questionnaire surveys, focus group discussion, and in-car tests. The main...

Many ancient sedimentary basins are interpreted as endorheic basins, internally drained basins with no direct hydrological connection to the marine environment. Some of these endorheic basins are economically important because of the abundance of hydrocarbon resources. To date, many studies have been conducted on fluvial systems in endorheic...

Crohn’s disease (CD) is a chronic inflammatory bowel disease (IBD) that affects millions of people in Europe alone. It is important to accurately assess the disease severity in a safe and non-invasive manner in order to improve the treatment of patients with CD. Furthermore, the ideal assessment must be objective, reproducible, quantitative and...

In this dissertation, we focus on exploiting superconvergence for discontinuous Galerkin methods and constructing a superconvergence extraction technique, in particular, Smoothness-Increasing Accuracy-Conserving (SIAC) filtering. The SIAC filtering technique is based on the superconvergence property of discontinuous Galerkin methods and aims to...

This thesis describes the theory, design and implementation of levelcrossing ADCs and their system integration. The goal of this work is to explore methods at both the circuit level and the system level to improve the energy efficiency of LC-ADCs and integrate LC-ADCs in biomedical readout systems. Two single-bit capacitive LC-ADCs and an ECG...

Orthotropic steel decks are widely utilized in long span bridges, movable bridges and shorter span road and rail bridges due to their favourable properties. These properties are low deadweight, large plastic reserves in case of overload and aesthetic advantages. Nowadays, more than 1000 orthotropic steel deck bridges (OSDBs) have been built in...

This thesis carried out two major investigations on how the geographical information generated by users in social media can be used to model and predict human behaviours. The first investigation regards the mobility patterns of social media users, which utilizes the relations between geographical information and other sources of information, e.g...

The geo-graphical location at which an image or video was taken is a key piece of multimedia information. Such geo-information has become an indispensable component of systems enabling personalized and context-aware multimedia services. The research reported in this thesis investigates how to automatically derive geo-information from multimedia...

As a significant phenomenon in meteorology, fog has attracted more and more concern from the scientific community, because of its impacts on visibility in air- and road-transportation. E.g., at airports, the frequency of aircrafts taking off and landing has to be reduced during heavy fogs, because in conditions of low visibility the pilots need...
