  • Patent number: 11644390
    Abstract: Systems and methods are disclosed herein for contextual data analysis and proactive intervention in industrial plant processes. Each of multiple data streams in an industrial plant are mapped to a common hierarchical data structure, wherein the data streams correspond to respective values or states associated with unit operations, assets, and process streams in the plant. The mapped data streams define hierarchical process relationships between subsets of the unit operations, assets, and process streams. Real-time data is collected to populate at least one level of the hierarchical data structure for certain data streams, wherein future outcomes are predicted for downstream operations based on the collected real-time data for at least one data stream, and at least one other data stream having a defined hierarchical process relationship therewith.

In one embodiment, the present invention provides a heat exchanger with a helicoidal shape that provides axial elastic compliance. In one embodiment, the internal channel of the heat exchanger varies along its length. The internal channel may have a cross-sectional area that increases progressively from one end to the other. In one embodiment, the external shape of the tubular structure may be non-circular to optimize heat transfer with an external heat transfer fluid. In one embodiment, the present invention provides a heat pipe with an internal wicking structure formed as an integral part of the additive manufacturing process.

  • Publication number: 20230057828
    Abstract: Methods and systems for circuit design are described. A tool may detect a timing violation on a signal path connected to a local clock buffer in a circuit model. The local clock buffer may be configured to generate a first clock signal having a first pulse width. The tool may determine a first metric associated with a first type of timing violation, and may determine a second metric associated with a second type of timing violation different from the first type of timing violation. The detected timing violation may be one of the first type and second type of timing violations. The tool may, based on the first metric and the second metric, determine whether to retain the generation of the first clock signal or to configure the local clock buffer to generate a second clock signal having a second pulse width different from the first pulse width.
