Peer-to-Peer Group Communication for City-Scale Mesh Networks
… repression, cyberattacks, and human error. CityMesh provides an answer to this problem, constructing a decentralized mesh network out of wireless access points. To test our unicast routing protocol, we built a discrete-event network simulator using SimPy. However, we make several simplifying …

City-scale Cross-view Geolocalization with Generalization to Unseen Environments
… environment while scaling efficiently to city-sized regions in unseen environments and working with either panoramic or non-panoramic cameras. One contribution is a trinomial loss function that enables accurate and computation-efficient localization across city-scale search areas of nearly …

Understanding travel mode choice: A new approach for city scale simulation
Understanding travel mode choice behaviour is key to effective management of transport networks, many of which are under increasing strain from rising travel demand. Conventional approaches to simulating mode choice typically make use of behavioural models either derived from stated preference …

City-scale eco-routing and pavement eco-maintenance scheduling for CO2 mitigation
… infrastructure asset management perspective, a city-scale pavement degradation model is built and utilised in testing pavement maintenance scenarios. San Francisco is chosen as the case study area due to the availability of various traffic mobility and infrastructure condition data. In Chapter 3 …

Developing an Activity-Based Model for City-Scale Cross-Sectoral Energy and Carbon Emissions Management
Emerging working patterns (such as home-based and flexible working) are becoming increasingly prevalent worldwide, reshaping how urban residents allocate their time and interact with the built environment. These structural shifts are changing the spatial and temporal distribution of energy demand …

Exploration of robotic-wheel technology for enhanced urban mobility and city scale omni-directional personal transportation
… impacts of omni-directional motion in the city are examined. The second section of the thesis presents built and rendered prototypes of these three designs. The third and final section, evaluates implementation issues including robotic controls and an algorithm necessary for real world …

Greenhouse gas mitigation cost of energy from biogas : a techno-economic analysis of co-digestion of three types of waste in Cape Town
… energy from biogas and related cost. Two project-scale models and a city-scale model were developed. Substrates for project model 1 were organic fraction of municipal solid waste (OFMSW) and primary sludge (PS) from sewage works. Project model 2 considered waste paper sludge (WPS) and PS. For the …

Combining theoretical concepts and tools: mapping human deprivation in the City of Cape Town
… that urgently nee4J to be addressed at the city scale. This research explores the argument that confusion over the measurement of human deprivation still exists, despite various development initiatives, in part because of a disconnect between contemporary development discourse and the …

Inundation Flooding in Urban Environments using on-lattice Density Functional Theory
… for porous materials this DFT model is herein upscaled from the nanoscale to the city scale. We show that the strength of such an equilibrium-based approach, which discards the timedependence of flooding, stems from a combination of three aspects. First, the model has a minimum of input …

Deep Learning Emulators for Accessible Climate Projections
… the links between policies, global warming, and city-scale impacts. Climate models have been incredibly helpful in generating this causal understanding, but running them requires supercomputers and is only accessible to the minority of researchers. This thesis explores how emulating climate …

Beyond city size : characterizing and predicting the location of urban amenities
Intercity studies have shown that a city's characteristics -ranging from infrastructure to crime-scale as a power of its population. These studies, however, have not been extended to the intra-city scale, leaving open the question of how urban characteristics are distributed within a city. Here we …
