Abstract: The present invention reveals a comprehensive health evaluation method and system for the top cover drainage system of a hydroelectric generating set. It analyzes health evaluation factors at multiple levels, processing the drainage system into a component evaluation set and a state variable evaluation set. A combined weighting method, incorporating both initial weight and objective weighting methods, is used for comprehensive weighting across the levels. Standard requirements and scoring criteria are established, enabling sequential calculation of scores from state variables to components, then to the top cover drainage system, progressing from low to high levels. This process evaluates the health degrees at each level, resulting in a comprehensive and reliable health evaluation outcome. Consequently, it effectively addresses technical issues in prior art, such as limitations in health evaluation methods and the low reliability and universality of evaluation results.

Abstract: Example methods and systems to implement an economic printing mode are described. In one example, a computer system may provide a user interface specifying multiple selectable levels associated with economic printing mode. The source printing content may be transformed to generate target printing content that is printable using a lower ink consumption compared to the source printing content. For example, in response to a selection of a first level, print quality may be reduced. In response to a selection of a second level, image information in the source printing content may be modified. In response to a selection of a third level, font information associated with textual information in the source printing content may be modified. The computer system may provide the target printing content that includes modified font information to the printer for printing and/or generate a preview of the target printing content prior to printing using the printer.

Abstract: Secure printing may be performed in a virtual desktop infrastructure (VDI) in a virtualized computing environment. When a file is selected for secure printing, print data for the file is stored, and a corresponding entry is created in a metadata map. A message is sent to a user device to inform a user that the file is available for secure printing. The message may include a uniform resource locator (URL) link having a hash code corresponding to the stored print data. If the user accesses the URL link to request the secure printing, the hash code is retrieved from the URL link and compared against the entry in the metadata map. If there is a match between the hash code and the entry in the metadata map, the file is sent to a target local printer for printing.
