  • Patent number: 10648805
    Abstract: A method for tracking and identifying a polluted air mass's transmission trajectory in real 3-D space. In one aspect, a polluted air mass's transmission path identification is based on a monitoring of PM2.5 concentration in cubic volumes of an air mass. The method computes a transmission path of polluted air that considers wind-pressure conversion, the displacement estimation with mass concentration, and planetary boundary layer (PBLP height constraint) for 3-D cubic grids. The resultant determination of a polluted air mass's transmission trajectory in real 3-D space generates more practical and reliable results for intensive knowledge of the transport pathways and potential pollution sources in real 3-D space.

  • Patent number: 10394266
    Abstract: According to embodiments of the present invention, the energy consumption assessment is done by identifying the benchmark production processes or enterprises. First, a process similarity between a target production process and a candidate production process is determined based on energy consumption units (ECUs) involved in the target production process and the candidate production process. In response to the process similarity being greater than a first threshold, an energy consumption similarity between the target production process and the candidate production process is determined based on a factor that has influence on energy consumption of at least one of the ECUs. In response to the energy consumption similarity being greater than a second threshold, the candidate production process is identified as a benchmark for assessing energy consumption of the target production process.

    Abstract: A particle concentration is determined by acquiring a particle concentration measurement at a reference station from each of a plurality of sensors to be evaluated. A reference particulate concentration measurement is acquired from a reference station sensor at the reference station. A base set of sensors is selected from the plurality of sensors based upon a correlation calculation. A reference sensor is selected from the base set of sensors. A model is constructed that specifies a relationship between the reference sensor and the reference station sensor. A generalized sensor type is formulated using one or more characteristics of the reference sensor. The generalized sensor type is used to construct an inheritance network model. A particle concentration for the generalized sensor type is determined based upon the inheritance network model.
