An empirical survey of the perceived benefits of implementing the Mandatory Building Inspection Scheme (MBIS) in Hong Kong
Purpose - This paper aims to review the current state of building decay in Hong Kong, and attempts to identify and analyze the perceived benefits of implementing the Mandatory Building Inspection S...
Active control of a turbulent round jet based on unsteady microjets
The manipulation of turbulent jet mixing performance possesses many potential benefits in various industrial applications. This work reports an experimental investigation on the active control of a...
The flow structure around an Ahmed vehicle model and its active control
The lasting high fuel cost has recently inspired resurgence in drag reduction research for vehicles. This work aims to gain a relatively thorough understanding of unsteady predominant coherent stru...
Hybrid FRP-concrete-steel double-skin tubular columns under static and cyclic loading
This thesis presents a systematic study on the structural behavior of hybrid FRP-concrete-steel double-skin tubular columns (hybrid DSTCs) under static and cyclic loading, with particular attention...
A study of radiation-induced carotid atherosclerosis in patients treated with radiotherapy for nasopharyngeal carcinoma
Carotid atherosclerosis is a common complication in patients treated with radiotherapy (RT) for nasopharyngeal carcinoma (NPC). Since patients with carotid atherosclerosis have a higher risk of cer...
Degradation of refractory contaminants in water by chemical-free radicals generated by ultrasound and UV irradiation
The contamination of water bodies by endocrine disrupting compounds (EDCs) has drawn increasing attention in recent decades because of their potential adverse effects on aquatic lives and human hea...
Named entity disambiguation from web text
Named entity disambiguation is the problem of grouping name mentions into clusters, with each cluster referring to the same underlying entity. In this thesis, we focus on named entity disambiguatio...
Complex network analysis of time series
Data in the form of time series are ubiquitous that they can be found everywhere and the analysis of time series has long been important for extracting meaningful statistics and valuable informatio...
Pedestrian level wind and thermal environment around buildings : wind tunnel investigations
Constructing a new building will always affect the microclimate at the building and its surrounding area. This can lead to low airflow or poor outdoor ventilation around the building blocks, which ...
Study of communication network performance from a complex network perspective
This thesis studies the performance of communication networks from a network science perspective. Our task is to establish a clear link between some structural properties of networks, such as degre...
Essays in transport economics and policy : policy evaluations in the aviation and maritime sectors
Major policies have been implemented and proposed in the aviation and maritime sectors in recent years, with various aims such as to improve financial performance of firms, to reduce pollution and ...
Improved earthquake slip distribution inversion with geodetic constraints
Earthquake is a natural disaster that can lead to a significant loss of lives and properties. Earthquake studies have been relying on the inversion of ground observations, including geodetic and se...
Protein subcellular localization : gene ontology based machine learning approaches
Proteins, which are essential macromolecules for organisms, need to be located in appropriate physiological contexts within a cell to exhibit tremendous diversity of biological functions. Aberrant ...
Accurate iris recognition at-a-distance and under less constrained environments
Accurate iris recognition using eye or face images acquired at-a-distance and under less constrained environments requires development of specialized iris segmentation and recognition strategies. I...
Statistical approach for activity-based model calibration based on plate scanning and traffic counts data
This thesis aims to contribute to the rapidly growing research area of route travel time estimations and travel demand model calibrations from traffic observations (vehicle identification data and ...
A case-based study on public-private-partnership projects in the urban water supply sector
This thesis points out that public-private partnership (PPP) is an effective procurement method for delivering public infrastructure, and the China government has the motivations to apply it to urb...
Development of decision making tools for street planning in high density cities
In recent decades, a vast number of tall buildings have been built in response to rapid process of urban city developments. However, the construction of tall buildings in urban streets has led to m...
Study on the coupled flow, heat and mass transfer processes in a liquid desiccant dehumidifier
At present, a large amount of energy is needed to create a livable indoor environment. It is estimated that the buildings sector consumed 28% ~ 30% of the total final energy in China. Among all the...
Residents' perceptions of non-casino gaming in urban communities : a comparative study between Hong Kong and Guangzhou
Non-casino gaming (e.g., horse racing, Mark six lotteries, football betting, Sports Lottery, Welfare Lottery) has grown considerably in Hong Kong and Guangzhou in recent years. Residents are the pr...
Development of plantar pressure relieving orthotic insoles for people with diabetes
Orthotic insoles are commonly used in the treatment of the diabetic foot to prevent ulcerations. The insoles are normally custom-made to provide an optimum fit and reduce and/or redistribute pressu...
