This research proposes an Activity Pattern embedded Air Pollution Exposure Model (AP2EM), based on survey data of when, where, and how people spend their time and indoor/outdoor ratios for microenvironments. AP2EM integrates random forest and agent-based approaches to simulate the stochastic...

Service refusal (i.e., providers refuse to provide service to users), which has become an increasingly serious problem in the sharing economy, remains unexplored. Through the application of rigorous identification strategies on a rich data set from a large sharing economy platform, this study...

Transesterification is the most common method of producing biodiesel from vegetable oils. A comparative study on the optimization of reaction variables for refined canola oil, unrefined canola oil, and unrefined camelina oil using a four-factor (temperature, time, molar ratio of methanol to oil,...
