Wei, Z. (author)Photoinduced charge transfer (CT) is a fundamental photophysical process that prevails in nature but also plays a pivotal role in various technological fields. This thesis describes spectroscopic studies on photoinduced CT in donor-bridge-acceptor (DBA) systems and their derivatives. Throughout this work, we employ femtosecond transient...doctoral thesis 2023

Wei, X. (author)This thesis addresses new methods and applications of ptychography which is a scanning Coherent Diffraction Imaging(CDI) method for reconstructing a complex valued object function from intensity measurements recorded in the Fraunhofer or Fresnel diffr- action region. The technique provides a solution to the so-called 'phase problem' and is found...doctoral thesis 2022

Wei, L. (author)Excessive fluoride (F¯) in drinking water due to natural and anthropogenic activities is a serious health hazard affecting humans worldwide. Groundwater is the major and preferred source of drinking water, also in developing countries. The removal of the excess F<sup>-</sup> from groundwater prior to drinking is important in terms of protection...doctoral thesis 2021

Wei, P. (author)Excess sludge handling is as important as treating the wastewater in determining the operational performance and costs in modern municipal wastewater treatment plants (WWTPs). In practice, excess sludge handling is widely implemented using anaerobic digestion (AD), in which the organic matter inside the sludge is not only stabilised and partly...doctoral thesis 2021

Wei, D. (author)The microscopicworld is surprisingly busywith swimming micro-organisms. In a droplet of pondwater, there can be tens of thousands of microbes. They are predators and preys, producers and consumers, and they formthe bottom levels of the ecology of our world. The swimming micro-organisms can be in general classified into prokaryotes and eukaryotes...doctoral thesis 2020

Wei, X. (author)Estuaries are important ecosystems accommodating a large variety of living species. Estuaries are also important to people by their demand of freshwater for drinking, irrigation, and industry. Due to natural changes and human activities, the estuarine water quality, influenced by both salinity and turbidity (the cloudiness or haziness of water),...doctoral thesis 2017

Wei, C. (author)Multi-robot teams have potential advantages over a single robot. Robots in a team can serve different functionalities, so a team of robots can be more efficient, robust and reliable than a single robot. In this dissertation, we are in particular interested in human level intelligent multi-robot teams. Social deliberation should be taken into...doctoral thesis 2015

Wei, X. (author)We present a three-dimensional model based on the finite element method for solving the time-harmonic Maxwell equation in optics. It applies to isotropic or anisotropic dielectrics and metals, and to many configurations such as an isolated scatterer in a multilayer, bi-gratings and crystals. We shall discuss the applications of the model to high...doctoral thesis 2006
