Abstract: A method for restoring waterbird habitats based on the “ecological leverage” theory is provided. The method includes: Step 1: Determining a target waterbird habitat to be restored based on the ecological environment of a target wetland area; Step 2: Selecting several suitable basic ecological units that are distributed in a scattered, circular, or S-shaped pattern from the target wetland area; Step 3: Optimizing the environment of the selected basic ecological units according to the target waterbird habitat; Step 4: Conducting long-term monitoring of the ecological environment and waterbird population of the optimized ecological units, assessing the restoration of the waterbird habitat, and further optimizing the ecological units based on the assessment results. The method of the present invention achieves an enhancement in waterbird diversity within a region with the minimum ecological space and waterbird habitat restoration efforts.

Abstract: Various implementations of the present disclosure relate to text to visualization. In a method, information items are extracted from a natural language sentence. Visual elements associated with the information items are determined. A visual representation of the natural language sentence based on the visual elements is determined, the visual representation indicating information expressed by the natural language sentence.

Abstract: A subsonic compressor, a rotor blade and a method for flow stability enhancement are provided. The subsonic compressor includes a hub and a casing, a tip clearance is formed between a tip of the rotor blade and an inner wall of the casing. The tip clearance is formed as a circumferential diverging leakage passage expanding from a pressure surface side of the rotor blade of the subsonic compressor at the tip to a suction surface side of the rotor blade at the tip.

Abstract: A vaneless contra-rotating compressor with multiple contra-rotating interfaces and application of the vaneless contra-rotating compressor is provided, which includes at least two vaneless contra-rotating interfaces. For each of the at least two contra-rotating interfaces, the contra-rotating interface corresponds to two of vaneless contra-rotating rotors. A rotating direction of an upstream rotor of the two vaneless contra-rotating rotors and a rotating direction of a downstream rotor of the two vaneless contra-rotating rotors are opposite. Rectifier stator vanes are not provided among all the rotors to supply sufficient inlet negative pre-swirl for the downstream rotors through the upstream rotors. Only the outlet guide vanes of the last stage, of the vaneless contra-rotating rotors are provided. The number of stages and the number of vaneless contra-rotating interfaces may be set flexibly according to the actual pressurization requirements.

Abstract: The present disclosure relates to systems, methods, and computer-readable media for training and implementing pipeline error detection models to facilitate automated detection of data quality (DQ) issues within recurring data pipelines. For example, systems described herein involve training a pipeline error detection model by first constructing a plurality of DQ constraints for a recurring data pipeline based on ranges of values observed over a history of pipeline executions. The systems may further train the model to predict DQ issues by synthetically applying data variants to historical executions of the recurring data pipeline or to data pipelines having similar characteristics thereto. Once trained, the pipeline error detection model(s) can be applied to new executions of the data pipeline as they become available to quickly and efficiently predict whether a given execution includes a predicted DQ issue therein.

Abstract: In accordance with the implementations of the subject matter described herein, there is provided a solution for reusing infographics. In this solution, a group of visual element units is determined from a visual element set comprised in the original infographic. A visual element unit in the group represents an information item in the original infographic. A first correlation between a visual element contained in the visual element unit and the information item and a second correlation between the visual element unit and a further visual element unit in the group are determined. A description for the original infographic is generated based on the first and second correlations. A target infographic is generated by updating the group of visual element units at least based on the description and the target information. In this way, infographics can be converted into reusable templates, thereby simplifying reuse of such infographics and improving user experience.
