This research project is designed to enhance the planning process that can aid authorities moving towards sustainable and economically feasible local and regional mobility systems. The improvements that have been made to transit so far have not been successful in breaking the
Fabricating nanostructures and tailoring their properties on the nanometer scales by conventional lithographic approaches are challenging. In particular, the creation of nanostructures with good alignment and uniform size, to enable and enhance desirable collective behaviors, is even more difficult. Such difficulties have
This thesis concerns the fabrication, characterization, and application of fibre Bragg gratings (FBGs). Being in-fibre wavelength-selective reflectors, FBGs have wide applications in optical communication and sensing systems. Compared with conventional bulk-optic gratings, FBGs offer the advantages of low loss, polarisation independence, compatibility
The keratinase gene (kerA) of Bacillus licheniformis ATCC®53757 was PCR amplified and subsequently cloned into Bacillus megaterium expression vector; pHIS1525.SPlipA and transformed in Bacillus megaterium ATCC®14945. The kerA gene carrying the recombinant plasmid pKERHIS1525.SPlipA was expressed in Bacillus megaterium under xylose inducible
Title: Experimental determination of parameters of tracks on solid state nuclear track detectors from alpha particles with different incident energies and angles The use of solid state nuclear track detectors (SSNTDs) has already become a well-known technique which has been widely applied
The features of the first jump of the seasonal march associated with the interannual variabilities of the East Asia summer monsoon (EASM) trough are studied. The northward march of the monsoon trough has been identified and two kinds of EASM are categorized.
Cylinder liner surface topology greatly affects oil consumption and wear of engines. Surface optimization would be greatly facilitated by automatic quality control. Surface roughness definitions, parameters, and measurement techniques were reviewed and samples of different Volvo truck engine cylinder liner types were
Pointing, acquisition, and tracking (PAT) systems have been widely applied in many applications, from short-range (e.g. human motion tracking) to long-haul (e.g. missile guidance) systems. This dissertation extends the PAT system into new territory: free space optical (FSO) communication system alignment, the
We studied the assembly behavior of a polybutadiene-b-poly(ethylene oxide) diblock copolymer in methanol, cyclohexane, and the corresponding partially miscible binary solvent system. Dynamic light scattering indicates that the copolymer forms coexisting spherical and cylindrical micelles in both of the pure solvents. In
Global energy consumption has been increasing around the world, owing to the rapid growth of industrialization and improvements in the standard of living. As a result, more carbon dioxide and nitrogen oxide are being released into the environment. Therefore, techniques for achieving
