Abstract: A fuel cell system, e.g., of a motor vehicle, includes a fuel cell stack having fuel cells and non-repeating hardware components, the latter including wet and dry end units. The cells are positioned between the end units. The dry end unit includes an end plate and a compression plate assembly that uniformly compresses the cells against the end plate, and a terminal plate surrounded by a seal plate. An insulator frame disposed adjacent to the compression plate assembly is engaged with the insulator frame via a frictional interface provided by o-ring compression seals having a respective post connected to the terminal plate and the seal plate, and a pocket connected to the insulator frame. The post and pocket of at least one of the compression seals together define a fluid passage. One or more shim plates may be disposed between the end plate and insulator frame.

Abstract: A current software tool is identified. The current software tool is used to manage and/or create a current corresponding software. For example, the current software tool may be a compiler and the current corresponding software may be a binary executable. A current mapping is generated between code provided to the current software tool and the current corresponding software using a first Artificial Intelligence (AI) algorithm. A comparison between the current mapping and a learned mapping is made to determine if the current software tool is manipulating the current corresponding software in an abnormal way. The learned mapping is based on historical code input into historical software tools and corresponding historical code output from the historical software tools. In response to determining that the current software tool is manipulating the current corresponding software in an abnormal way, the current software tool is identified as being compromised or likely compromised.

Abstract: Apparatuses, method, systems, and program products are disclosed for assessing instructor ratings on a defined rating scale for skewness. An apparatus includes a processor and a memory that stores code executable by the processor. The code, when executed by the processor, receives a raw instructor rating data set, comprising a plurality of ratings from an individual instructor, on a defined rating scale. The code is executable to determine a rating skewness of the raw instructor data set by subtracting a central tendency measure of the plurality of ratings from a central tendency measure of the defined rating scale, and dividing the result by the standard deviation of the plurality of ratings. The code is further executable to compare the rating skewness of the raw instructors rating data set to at least one comparative rating skewness to generate a skewness comparison report.

Abstract: The techniques disclosed herein enable systems to efficiently interface with zoned namespace (ZNS) storage devices through a specialized management entity. To achieve this, the management entity receives write requests from a file system containing data intended for storage at the ZNS device. In response, the management entity selects a zone from the ZNS device to write the file data to. Accordingly, the file data is written by appending the file data to the zone at a location indicated by a write pointer. When the write operation is completed, the offset of the file data within the zone is observed and recorded by the file system in file metadata. In contrast to typical systems which allocate locations at the storage device prior to writing, appending file data and then recording the location enables improved efficiency in file system operations. Namely, that write operations can be issued to the ZNS device non-serially.

Abstract: The system described herein introduces a cache that a file system uses to determine, for a current object, if the process to merge different types of access control information into merged access control information has already been performed for a previous object. Stated alternatively, the file system uses the cache to determine whether a current object being processed for storage has the same combination of access control information as a previous object that has already been processed for storage. If the current object has the same combination of access control information as the previous object, the file system is able to associate merged access control information for the previous object with the current object via the use of a pointer. Consequently, the file system avoids having to perform the resource-intensive process of merging the different types of access control information for the current object.

Abstract: The present invention provides solution to the above-mentioned problem in the art by providing a system and a method for efficiently identifying from a medical domain a plurality of entities that may be designed and engineered for a diagnostic reasoning system or symptom checker. The identified plurality of entities forms nodes of a knowledge graph and may be interconnected to each other with edges representing finely curated weights. The curated weights may form a dynamic repository that can constantly evolves to best reflect the latest medical knowledge. Apart from diseases and symptoms, the system is also capable of extending and scaling to other dimensions of medical knowledge. The knowledge graph thus developed is fundamental to the entire diagnostic system and is used by various components of the diagnostic engine to power the AI-based reasoning.
