Dynamics of a supersonic flow over a backward/forward-facing step

The backward/forward-facing step (BFS/FFS) is one of the canonical geometries in aerospace engineering applications, the flow field over which has attracted extensive attention in the past decades. In a supersonic flow, laminar-to-turbulent transition and shock wave/boundary layer interaction (SWBLI) can occur over these configurations, which...

Container transport inside the port area and to the hinterland

This thesis discusses the connection between container terminals and the hinterland railway system. Mathematical models are proposed to formulate the various relevant operations and methods are developed to provide solutions to improve the system performance. This thesis could provide suggestions to decision maker(s) regarding to the improvement...

Rotational dynamics of viscoelastic planetary bodies

Signal strength based localization and path-loss exponent self-estimation in wireless networks

Wireless communications and networking are gradually permeating our life and substantially influencing every corner of this world. Wireless devices, particularly<br/>those of small size, will take part in this trend more widely, efficiently, seamlessly and smartly. Techniques requiring only limited resources, especially in terms of hardware, are...

Micro-pollutant removal from wastewater treatment plant effluent by activated carbon

In the recent years, the removal of micro-pollutants from treated wastewater has been highly advocated throughout Europe and the rest of the world. The relevant regulations and the suitable techniques have been proposed accordingly, which promoted the innovation of the conventional wastewater treatment plants (WWTPs). Activated carbon adsorption...

Tidal flat landscape formation and evolution

Tidal flat landscape formation and evolution are closely related to the biotic and abiotic processes that take place in the intertidal environments. Extensive studies have been carried out on the relevant agents such as hydrodynamics, sediment transport and the related ecosystem (vegetation and benthic communities) dynamics. However, the...

Water Tower of the Yellow River in a Changing Climate: Toward an integrated assessment

Climate change due to increasing greenhouse gas emissions is likely to alter the hydrological cycle resulting in large impacts on water resources worldwide. Mountain regions are important sources of freshwater for the entire globe, but their role in global water resources could be significantly altered by climate change. Mountains are expected...

Magnetic Density Separation of Polyolefin Wastes

Polymer recycling has significantly positive impacts on the environment, economics and society. Using recycled polymer to replace virgins reduces the growing amount of post-consumer polymer wastes, decreases the demand for fossil fuel and creates local jobs. As the most used polymer types, polyolefins certainly have attracted attention of...

Towards Contextualized Information Delivery: A Rule-based Architecture for the Domain of Mobile Police Work

An increasing number of mobile users demand adaptive services tailored to their specific requirements in a particular situation. Typically, when carrying out the task at hand, police officers need to have up-to-date information contextualized to their current situation in order to support their decision making. In contrast to the traditional...

Porosity of Concrete - Morphological Study of Model Concrete

This study has developed a comprehensive methodological framework for characterizing geometrical and morphological aspects of pore space in cementitious materials and explored its application to actual cement pastes and model concretes for the purpose of predicting mechanical and transport properties of cementitious materials. The evolution of...
