Analysis of the reverse trip directions of overnight workers from smart card data

Many overnight workers rely on public transit for commuting to work at night and from work in the morning. However, it is challenging to understand overnight workers’ travel patterns between origins and destinations due to their reverse travel directions compared to traditional daytime workers. This research proposes a methodology to identify the overnight workers’ travel […]

Validation of physics-based response prediction using deep learning

Infrastructures including buildings and bridges show dynamic behaviors due to earthquakes, wind loads, and etc. The excessive dynamic response sometimes leads to structural failure. Therefore, accurate prediction method of the dynamic response for the structures is required to secure the safety the structures. A neural network augmented physics (NNAP) model which is based on deep […]

Data Structures for Range Closest Pair Queries

The objective of this project is to construct optimal data structures for the range closest pair (RCP) problem. The RCP problem aims to construct a data structure such that whenever a specific query range is given, the closest point-pair among those inside the given range can be reported efficiently. The RCP problem has been studied […]

Health Behavior and Population Health in the Era of Climate Change

Climate change is closely tied with human behaviors and health. With continuous industrialization and technological advances, modern people are living unimaginable prosperous lives. However, their increased greed leads to enormous environmental destruction, such as the indiscriminate consumption of air conditioners and disposable products, and short-distance driving. Air pollution has a bilateral relationship with climate change, […]

Identifying local factors and sources affecting stream chloride concentrations in the Toronto Region

The proposed research will identify the dominant drivers of rising chloride concentrations in streams within the Toronto and Region Conservation Authority (TRCA) jurisdiction. The TRCA monitors stream water quality at 47 stations and data suggest that chloride concentrations are increasing. Previous research has identified urban growth and the subsequent application of road salt in wintertime […]

Structure-Activity Relationships of Hafnium Dioxide Nanoparticles for Cancer Radiotherapy and Imaging

Nanoparticles made from hafnium dioxide (hafnia; HfO2) have emerged as a potential enhancer of cancer radiation therapy. Such nanoparticles allow for reduced doses of radiation to be used on tumors, sparing healthy tissue from side effects without reducing its anti-cancer effects. However, despite their potential, it is not yet known how different nanoparticle properties, such […]

Analyzing User Reviews of Mobile Applicationsusing Natural Language Processing

The proposed project is to research and develop a user review analysis system for mobile games using machine learning and natural language processing techniques. Traditionally, user review analyses are done by humans, which is inefficient and relatively slow. The project will involve research in the specific areas of topic modeling, sentiment analysis and opinion spam […]
