  • Publication number: 20260119491
    Abstract: A system receives ETL specification for processing stream data, including a transform operation represented using a database query specification. The system generates a dataflow graph of a sequence of database queries by decomposing the database query into a first database query that generates an intermediate results table, and a second database query that receives as input the intermediate results table and outputs data used for performing the transform operation. The system executes the sequence of database queries for performing the transform operation on stream data received from the source. When receiving an incremental data set, the system determines an output change set based on the received incremental data set by traversing an execution plan and processing each operator in the execution plan, and computing a change set of a particular operator from the change sets output by the one or more other operators based on the incremental data set.

  • Publication number: 20170262869
    Abstract: To evaluate impact to a brand on social media, a computer is used to crawl through social media postings of social media services to select postings relating to one or more sponsored events. The selected postings are analyzed by computer to quantify keywords relating to particular brands. Images posted within the selected postings are also analyzed, using a pattern matching algorithm, to quantify depictions of the one or more brands within the images.

  • Patent number: 9652841
    Abstract: A control system for a froth flotation system receives inputs from one or more sensors comprising images of a fluid having bubbles and particles therein; some of the bubbles are attached to some of the particles and suspended in the fluid. For at least some of the bubbles with attached particles, it is determined from the inputs at least two contact angles at different locations at which the respective bubble is attached to the particle. These contact angles are used to predict a process improvement by which bubbles would more efficiently float the particles out of the fluid, as compared to that represented by the input images. An output is then provided for driving a graphical display screen, the output comprising at least one of: a) a graphical representation of the determined at least two contact angles; and b) a graphical representation of the predicted process improvement.
