摘要： A powder metal part is made by compaction at room temperature or an elevated temperature followed by sintering, a secondary densification, heat treating, and optional secondary operations. The particulate materials preferably include iron, 0-2.0 wt % copper, 0.15-0.9 wt % carbon, 0.5-2.0 wt % molybdenum, 0.5-4.5 wt % nickel, 0-4.0 wt % chromium, and 0-1.5 wt % silicon. At least one secondary densification is applied to the part after compaction and pre-sinter/sinters steps to achieve medium to high density. The secondary densification is part of a double-press double-sinter (DPDS) or is a mechanical working depending on the application requirements. The powder metal is heat treated by austempering or marquenching followed by tempering. A unique composite microstructure is achieved from austempering by controlling the powder chemistry and the holding time at an elevated temperature. The combination of a secondary densification and austempering or marquenching produces a high performance powder metal part for demanding applications.

摘要： A real time end-to-end learning system for a high frame rate video compressive sensing network is described. The slow reconstruction speed of conventional compressive sensing approaches is overcome by directly modeling an inverse mapping from compressed domain to original domain in a single forward propagation. Through processing massive unlabeled video data such a mapping is learned by a neural network using data-driven methods. Systems and methods according to this disclosure incorporate a multi-rate convolutional neural network (CNN) and a synthesizing recurrent neural network (RNN) to achieve real time compression and reconstruction of video data.

摘要： This disclosure addresses the single-image compressive sensing (CS) and reconstruction problem. A scalable Laplacian pyramid reconstructive adversarial network (LAPRAN) facilitates high-fidelity, flexible and fast CS image reconstruction. LAPRAN progressively reconstructs an image following the concept of the Laplacian pyramid through multiple stages of reconstructive adversarial networks (RANs). At each pyramid level, CS measurements are fused with a contextual latent vector to generate a high-frequency image residual. Consequently, LAPRAN can produce hierarchies of reconstructed images and each with an incremental resolution and improved quality. The scalable pyramid structure of LAPRAN enables high-fidelity CS reconstruction with a flexible resolution that is adaptive to a wide range of compression ratios (CRs), which is infeasible with existing methods.

摘要： An organizational chart view can include a plurality of icons each representing a person in an organization that are arranged to reflect a hierarchical organizational structure of the organization. A received first user input can include designation of two or more of the plurality of icons as part of a selected population, and a received second user input can include a selection of an analytical view to be applied to the selected population. The organizational chart view can be morphed to the selected analytical view, for example by generating animation effects to translate the plurality of icons in the selected population to form the selected analytical view.

摘要： A pivoting and swiveling floor treatment appliance includes a lock-prevention member that prevents a body from becoming pivotally locked in a forward/backward direction when a portion of the body is in a swiveled position. The lock-prevention member may move relative to an appliance head and to a portion of the body that swivels. In some embodiments, components of the lock-prevention member contribute to locking the swivel of the body when the body is pivotally locked.
