Exacerbations of chronic obstructive pulmonary disease (COPD) are associated with loss of lung function, poor quality of life, loss of exercise capacity, risk of serious cardiovascular events, hospitalization, and death.However, patients underreport exacerbations, and evidence suggests that unreported exacerbations have similar negative health impl
Accurate land-use/-cover change (LUCC) simulation is of great significance to issues closely related to regional planning and policy-making.Many models have been committed to conducting LUCC simulations for better decision-making.However, LUCC is a nonlinear spatiotemporal process with complex links and feedback as well as latent dependencies in bo
In this paper, we propose an efficient sound propagation and remapping technique based on geometry to enhance immersive sound effects in virtual environments, and suggest a method to interactively represent sound by considering the altitude and slope of the terrain.The proposed technique can represent real-time patterns of sound such as waves and f
