1. Interpretation of gamma-ray burst X-ray and optical afterglow emission : From the central engine to the circumburst interaction
Abstract : Gamma-ray bursts are the largest electromagnetic explosions known to happen in the Universe and are associated with the collapse of stellar progenitors into blackholes. After an energetic prompt emission phase, lasting typically less than a minute and emitted in the gamma-rays, a long-lived afterglow phase starts. READ MORE

2. Particle motion, coating and drying in Wurster fluidized beds - An experimental and discrete element modeling study
Abstract : This thesis focuses on developing a mathematical model that is capable of predicting the fluidized bed coating process. First a basic understanding of pellet motion in a Wurster fluidized bed was established by conducting a series of experiments using the positron emission particle tracking (PEPT) technique. READ MORE

3. All Digital Polar Transmitter Design for Software Defined Radio : Architecture and Low Power Circuit Implementation
Abstract : The evolving wireless communication technology is aiming highdata rate, high mobility, long distance and at the meantime, co-existwith various different standards. This developing trend requires ahighly linear transceiver system and it causes the problem of lowefficiency due to the large crest factor of signals. READ MORE

4. Impacts of Thermo-Physical Properties on Chemical Absorption for CO2 Capture
Abstract : Following the climate change mitigation target in Paris agreement, the global warming has to be limited to 2.0°C above the preindustrial levels. One of the potential methods is carbon capture and storage (CCS), which can significantly reduce the CO2 emissions from the vast point sources such as power plants, industries, and natural gas processes.

5. Property Impacts on Heat Exchanger Design in CO2 Cryogenic Process of Carbon Capture and Storage
Abstract : Carbon capture and storage (CCS) is one of the most promising technologies which can significantly reduce CO2 emissions. A better understanding of thermo-physical properties of CO2 mixtures is required for the design and operation of different CCS processes. READ MORE
