Purpose of Review Air quality modelling and forecasting have been well recognised to play important roles in environmental research as well as government policy assessments and management strategies. To address the recent progresses in air quality modelling, we conduct a literature review focusing on air quality forecasting models and reanalysis datasets. Recent Findings First of all, the implementation of three-dimensional ad...

In this study, an online path planning strategy capable of traversing narrow passages is proposed for an autonomous underwater vehicle equipped only with forward-looking sonar in unknown environments. First, to establish the environment model, the sonar fan-shaped detection area is subdivided into multiple sectorial grids. Then, a comprehensive cost function combining safety, smoothness, and cost is utilized to generate the op...
