Multi-scale study of rejuvenation mechanism and evaluation method for aged bitumen recycling

The increasing popularity of sustainable asphalt pavement stems from its advantageous attributes, such as cost-saving, environmental protection, and reductions in energy and material consumption. Although there is a desire to maximize the reuse of reclaimed asphalt (RA) waste materials in road construction, this is hindered by the poor...

Accelerating DNA Variant Calling Algorithms on High Performance Computing Systems

Next generation sequencing (NGS) technologies have transformed the landscape of genomic research. With the significant advances in NGS technologies, DNA sequencing is more affordable and accessible than ever before. Meanwhile, many DNA sequence analysis tools have been developed to derive useful information from the raw sequencing data produced...

Imaging systems in the Delft Multi-Beam Scanning Electron Microscope 1

The goal of this Ph.D. research is to develop imaging systems for the multiple beam scanning electron microscope (MBSEM) built in Delft University of Technology. This thesis includes two imaging systems, transmission electron (TE) imaging system, and secondary electron (SE) imaging system. The major conclusions, key results and some suggestions...

Benefits of Compute-and-Forward in Throughput, Energy, and Security

Optimisation of the Crack Pattern in Continuously Reinforced Concrete Pavements

Recent field investigations on several new Continuously Reinforced Concrete Pavements (CRCP) in Belgium indicate that its crack pattern is characterized by low mean crack spacing along with a high percentage of clusters of closely spaced cracks. Field surveys also indicate that it is difficult to significantly reduce the probability of a non...

Super-terahertz heterodyne spectrometer using a quantum cascade laser

High-resolution spectroscopy at super-terahertz frequencies (2-6 THz) can play a vital role in astronomical observation and atmospheric remote sensing. It provides unique and important information on the history of our universe and its evolution, by getting into the insight of the physical and chemical conditions. Moreover, it can help to...
