Abstract: An illustrative computing system for an intelligent web service verification and validation system processes base input to identify a web service for testing. The intelligent web service verification and validation system processes user defined functional inputs, expected outputs, and assertions with a machine learning engine to provide functional inputs, expected outputs, and assertions based on provided input. The intelligent web service verification and validation system generates a test case pattern, such as a minimally sized test case pattern for regression testing. The intelligent web service verification and validation system executes testing of the service based on the test case pattern and logs test data in a data repository. The intelligent web service verification and validation system analyzes validation and test information, including inputs, outputs, and assertions, using a machine learning algorithm to improve future input and test case generation and testing procedures for the web service.

The main port includes a hub body, a compressible seal disposed within the hub body, a pusher at least partially positioned within the hub body and slidably movable relative thereto, and a lock nut surrounding the pusher. The lock nut is threadably engaged with the hub body such that rotation of the lock nut moves the pusher axially toward and/or away from the compressible seal.

Abstract: The techniques disclosed herein enable systems to store file system metadata on append-only storage devices by the introduction of a metadata layout and relative references. To achieve this, a system analyzes a file metadata structure to select an approach to storing the metadata structure on the storage device. If the metadata structure is above a threshold size, it is separated into layers that are then appended to the storage device from lowest to highest. An offset is retrieved for appended layers and provided to upper-level layers that refer to them until the full structure is stored. For storing smaller pieces of metadata that refer to each other, the system configures upper-level nodes with relative references that express the location of metadata relative to the node. This enables atomic write operations for smaller metadata structures and/or portions of larger structures.

Abstract: A method and/or system for automated estimation of 3D orientation of a physical asset using deep learning models and computer vision algorithms, according to one or more embodiments. The system may be configured to receive images of the physical asset and camera orientation data as input, use deep learning neural network models to isolate the physical assets across the images, track each physical asset instance throughout the images and derive a 3D point cloud model of each asset by projecting binary masks of the asset contours from different view-points. The 3D point cloud model is further processed and supplemented with camera orientation data to estimate the 3D orientation of one or more assets present in the images.

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: Methods, computer systems, and computer-storage medium are provided for monitoring, analyzing, and providing reports regarding direct access technologies, for example DirectAccess, VPN, or VPN-like technologies. User activity associated with DirectAccess servers can be filtered by server location to allow administrators to determine which users, and how many users, utilized or are utilizing each DirectAccess server, which can be identified by geographic locations. In some cases, this information can be used to address technical support issues or to determine which resources of an entity may be under- or over-utilized.

Abstract: A processing system manages an ordered set of hierarchical data structures representing snapshots that define the state of a filesystem at different points in time. The data structures include nodes that store strong references, which can be utilized to read or write data, or weak references that can be only utilized to read data. In order to create a new snapshot, a root node is created for a new data structure representing the new snapshot by copying the root node of the data structure representing an active view of the filesystem. Any strong references stored in the copy of the root node are then changed to weak references. Snapshotting operations can then be performed with respect to the new snapshot utilizing the weak references stored in the root node of the new data structure.

Abstract: Techniques for learning and using content type embeddings. The content type embeddings have the useful property that a distance in an embedding space between two content type embeddings corresponds to a semantic similarity between the two content types represented by the two content type embeddings. The closer the distance in the space, the more the two content types are semantically similar. The farther the distance in the space, the less the two content types are semantically similar. The learned content type embeddings can be used in a content suggestion system as machine learning features to improve content suggestions to end-users.

Abstract: A computer implemented method manages storage. A number of processor units receive a request for a storage for an application. The number of processor units identify application storage requirements for the application in response to receiving the request for the storage for the application. The number of processor units identify a storage profile based on the application storage requirements in the request. The storage profile describes the storage for use by the application. The number of processor units returns the storage having the profile for use by the application to access the storage.

Abstract: A variety of medical procedures utilize two or more medical device components, including medical device components where a first medical device component is advanced within a second medical component. An example would be an elongate dilator used in combination with a guide catheter. The guide catheter and the elongate dilator may be adapted to provide a rotational lock mechanism that allows the guide catheter and the elongate dilator to lock together such that rotating one of the components causes rotation of both components. In some instances, the guide catheter and the elongate dilator may cooperate to also provide a relative axial lock between the two components.
