Abstract: Data characterizing a first set of locations of a plurality of sensors at an industrial site is received. Gas concentration, wind velocity at the industrial site, and an identified leakage area at the industrial site are detected by the plurality of sensors. Locations and leakage rates of one or more leakage sources is determined in the identified leakage area by a predictive dispersion model. The predictive dispersion model is configured to receive the wind velocity at the industrial site and the locations and leakage rates of the one or more potential leakage sources as input and generate the set of estimated gas concentration as output. A comparative metric based on the set of estimated gas concentrations is compared to the detected gas concentrations. The selected location and leakage rates of the potential leakage sources in a current iteration of the iterative determination are provided.

Abstract: A method includes receiving data characterizing locations of potential sources and of potential sensors at an industrial site, and receiving data characterizing a plurality of wind velocities at the industrial site. The method includes calculating a first prediction error of localization associated with a first set of potential sensors of the plurality of potential sensors, calculating a second prediction error of localization associated with a second set of potential sensors of the plurality of potential sensors, the calculating being based on a second set of scenario prediction errors associated with the plurality of scenarios, and selecting the first set of potential sensors to provide locations associated the first sub-set of potential sensors.

Abstract: Techniques are described herein that are capable of monitoring connectivity and latency of network links in virtual networks. For instance, a ping agent injects first ping packets into network traffic on behalf of hosts in the virtual network. The ping agent monitors incoming packets to identify first ping response packets, which are in response to the first ping packets, among the incoming packets. A ping responder rule that is included in inbound packet filter rules for a port in a virtual switch intercepts second ping packets in the network traffic. The ping responder rule converts the second ping packets into second ping response packets and injects the second ping response packets into outbound packet filter rules to be transferred to sources from which the second ping packets are received.
