Contaminant Source Identification from Finite Sensor Data: Perron–Frobenius Operator and Bayesian Inference
نویسندگان
چکیده
Sensors in the built environment ensure safety and comfort by tracking contaminants occupied space. In event of contaminant release, it is important to use limited sensor data rapidly accurately identify release location contaminant. Identification will enable subsequent remediation as well evacuation decision-making. previous work, we used an operator theoretic approach—based on Perron–Frobenius (PF) operator—to estimate concentration distribution domain given a finite amount streaming data. current approach extended most probable location. The identification framed Bayesian inference problem. requires considering multiple scenarios, which done efficiently using discrete PF operator. provides fast, effective accurate model for transport modeling. utility our PF-based methodology illustrated single-point scenarios both two three-dimensional cases. method accurate, efficient framework real-time source

Probabilistic Contaminant Source Identification in Water Distribution Infrastructure Systems
Large water distribution systems can be highly vulnerable to penetration of contaminant factors caused by different means including deliberate contamination injections. As contaminants quickly spread into a water distribution network, rapid characterization of the pollution source has a high measure of importance for early warning assessment and disaster management. In this paper, a methodology...

متن کاملStochastic Event Reconstruction of Atmospheric Contaminant Dispersion Using Bayesian Inference
Environmental sensors have been deployed in various cities for early detection of contaminant releases into the atmosphere. Event reconstruction and improved dispersion modeling capabilities are needed to estimate the extent of contamination, which is required to implement effective strategies in emergency management. To this end, a stochastic event reconstruction capability that can process in...
