Estimating crowd density and their emotions for city events using social media images

Event managers at large city events use crowd density as a metric in the process of maintaining safety at large scale city events. Identifying the density of crowds at these events relies on expensive physical infrastructure to work well or have limited accuracy. We propose amethod that addresses the gap of not relying on physical infrastructure...

Interacting Particle System-based Estimation of Reach Probability for a Generalized Stochastic Hybrid System

This paper studies estimation of reach probability for a generalized stochastic hybrid system (GSHS). For diffusion processes a well-developed approach in reach probability estimation is to introduce a suitable factorization of the reach probability and then to estimate these factors through simulation of an Interacting Particle System (IPS)....

Emergent Behaviour of Trajectory Based Operations Under Very High En-route Traffic Demand

Effective collaboration between planning controller, tactical controller and pilots in handling various uncertainties and hazards is the result of decades of evolutionary development. The forthcoming paradigm shift to Trajectory Based Operations (TBO) requires a similarly effective collaboration between the TBO layer and a tactical layer....
