Agent-Based Modelling And Big Data: Applications For Maritime Traffic Analysis, Marc Sirizzotti
Agent-Based Modelling And Big Data: Applications For Maritime Traffic Analysis, Marc Sirizzotti
Theses and Dissertations (Comprehensive)
Agent based modeling (ABM) is a powerful tool for examining complex systems in many scientific applications, including maritime transport systems. Growing demands for freight transport and increased industry emphasis on reducing environmental impacts have heightened the focus on vessel and port efficiency. This research aimed to create a maritime route planning model to simulate vessel movement in all waterways. The goal of the ship routing model developed in this research was to develop a simulation tool capable of reproducing real world shipping routes useful for navigation planning, with emphasis on port scheduling and potential application for further use and exploration. …
Factors Limiting Sand Dune Restoration In Northwest Beach, Point Pelee National Park, Canada, Pritichhanda Nayak, Pritichhanda Mohanty Nayak
Factors Limiting Sand Dune Restoration In Northwest Beach, Point Pelee National Park, Canada, Pritichhanda Nayak, Pritichhanda Mohanty Nayak
Theses and Dissertations (Comprehensive)
Known as home to rare species of flora and fauna, and their critical habitats, Northwest beach of Point Pelee National Park has undergone significant ecological and infrastructural changes in the past decades. A number of important management challenges have emerged, including conservation of endangered Five-lined Skink (Plestiodon fasciatus) which inhabit the extensive dune system within the park. This research investigates key factors for sand dune ecosystem restoration in Northwest beach of Point Pelee with particular attention to the conservation of Skink habitat. Random stratified sampling method was used to collect sand and vegetation samples from the disturbed and …
Space-Time Modelling Of Emerging Infectious Diseases: Assessing Leptospirosis Risk In Sri Lanka, Cameron C F Plouffe
Space-Time Modelling Of Emerging Infectious Diseases: Assessing Leptospirosis Risk In Sri Lanka, Cameron C F Plouffe
Theses and Dissertations (Comprehensive)
In this research, models were developed to analyze leptospirosis incidence in Sri Lanka and its relation to rainfall. Before any leptospirosis risk models were developed, rainfall data were evaluated from an agro-ecological monitoring network for producing maps of total monthly rainfall in Sri Lanka. Four spatial interpolation techniques were compared: inverse distance weighting, thin-plate splines, ordinary kriging, and Bayesian kriging. Error metrics were used to validate interpolations against independent data. Satellite data were used to assess the spatial pattern of rainfall. Results indicated that Bayesian kriging and splines performed best in low and high rainfall, respectively. Rainfall maps generated from …
Analysis Of The Geosocial Landscape In The City Of Toronto, Courtney J. Jones
Analysis Of The Geosocial Landscape In The City Of Toronto, Courtney J. Jones
Theses and Dissertations (Comprehensive)
Microblogging on geosocial platforms is a popular form of online communication where users post information about their daily lives and challenges. Since the launch of Twitter in 2006, information sharing through social media has become a largely unused data repository. Tweets often convey content about the users sentiment as it is happening. As such, Tweets can be viewed as a proxy of public mood. In this thesis, I performed a sentiment analysis of all public geo-located Tweets posted by a variety of Twitter users between September 2013 and October 2014. Each Tweet was processed through a custom algorithm to extract …
Japanese Encephalitis: Assessing Disease Risk Due To Landscape Factors At Multiple Scales, Julia E. Metelka
Japanese Encephalitis: Assessing Disease Risk Due To Landscape Factors At Multiple Scales, Julia E. Metelka
Theses and Dissertations (Comprehensive)
Japanese Encephalitis is a mosquito-borne disease and is the leading cause of viral encephalitis in Asia. In many Asian countries, the geographical distribution of JE is dependent on a variety of human-environment interactions that can be conceptualized as a complex social-ecological system. The JE transmission cycle is influenced by a few primary human-landscape factors; the abundance and the spatial configuration of rice paddy fields (which provide habitat for the vector), the distribution of pig farms (which position the virus' amplifying host), and the location of a susceptible human population. Our models integrate population dynamics, landscape characteristics, and weather variables that …
