Abstract: A balance disorder rehabilitation robot based on virtual and real scene fusion has a follow-up supporting device, a weight loss protection device and a virtual projection device. The follow-up supporting device is arranged in the center position of a bottom surface of the weight loss protection device and is used to follow the balance training gait of a patient in real time. The weight loss protection device is used to follow the position of center of gravity of the patient in a process of balance rehabilitation training in real time. The virtual projection device is arranged in front of the follow-up supporting device to present a virtual scene. The postures and the positions of the follow-up platforms are controlled to realize the physical sense reproduction of multiple motion scenes. The physical scene is organically combined with the virtual scene to ensure a diverse balance rehabilitation training environment.

Abstract: Disclosed are a machining method and a machining device improving machining efficiency and preserving workpiece surface integrity. The machining method improving machining efficiency and preserving workpiece surface integrity includes: setting a workpiece (300) and a machining unit (400); and machining the workpiece (300) by the machining unit (400) at a preset machining speed, wherein the preset machining speed is not lower than a machining speed corresponding to the embrittlement of the workpiece material. By the machining method, the machining speed of the machining unit (400) is set during machining, which results in “skin effect” of subsurface damage caused by the embrittlement of the workpiece material (300) and enables the damage depth of the workpiece (300) to be confined in a shallow subsurface layer, so that the damage depth of the workpiece (300) is reduced, the workpiece integrity is preserved, and the machining quality and the machining efficiency are improved.

Abstract: A search management system and method to perform a search of first set of records maintained in a transactional data store (e.g., a commit log of a relational data store) and a second set of records maintained in a batch-updated data store. The search results corresponding to the transactional data store and the batch-updated data store are merged to generate a search result dataset to provide in response to a search query. The transactional layer or transaction data store is a commit log configured to manage and store records in accordance with recently executed operations (e.g., add and delete record operations) based on communications with one or more customer systems relating to customer data. Records maintained in the commit log are subsequently stored in the batch-updated data store as a result of a batching process.

Abstract: A data set may be partitioned according to relative differences indicated by a cover tree. A cover tree may be generated for a data set. Items in the data set may be stored at the same or different nodes according to the relative difference between the items indicated in the cover tree. Portions of the cover tree may be assigned to different nodes storing the data set. Access requests for the data set may be performed by sending the access requests to nodes identified according to the assigned portions of the cover tree.

Abstract: An event applier service obtains state change information for a plurality of software containers from a transaction journal. Based at least in part on operations specified in the state change information for the plurality of software containers, the event applier service generates event data for the plurality of containers. The event applier service updates a database to indicate that the state change information has been processed to generate the event data. The event applier service provides the event data.

Abstract: A method and system for processing images by a neural network are provided. A first computer can sequentially transfer at least two versions of an image having increasingly greater resolution to a second computer. The second computer performs an image identification process on each of the sequentially transferred at least two versions until the image is identified.

Abstract: At least one instance of an application is launched in a set of software containers that are distributed among a set of virtual machine instances. A set of measurements corresponding to resource utilization by a software container of the set of software containers is obtained and a timestamp is generated for the set of measurements. The set of measurements is aggregated, with other sets of measurements corresponding to the set of software containers for the application, into a set of aggregated measurements grouped in a time window group, based at least in part on the timestamp, and, as a result of fulfillment of a condition, the time window group is outputted.

Abstract: A processing device receives a representation of an image, wherein the image has a first size and the representation has a second size that is smaller than the first size, the representation having been generated from the image by a first portion of a first trained machine learning model. The processing device processes the representation of the image using a second portion of the trained machine learning model to generate a reconstruction of the image and then outputs the reconstruction of the image.

Abstract: An artificial turf is formed of grass fibers, a grass bottom and a rear glue. The grass fibers and the grass bottom are both made from polyethylene, polypropylene and/or polyamide, and the rear glue is mainly made from ethylene-vinyl acetate copolymer emulsion with filler and antioxidant, etc. The artificial turf is manufactured by making the rear-adhesive components into glue paste and coating it on the rear of the grass bottom fixed with grass fibers.

Abstract: A vibration assisted tapping device includes an elastic frame for translating axial vibration to a vibration having both axial and torsional components. The elastic frame has flexural members that connect an upper plate to a lower plate with a vibratory actuator preloaded therebetween. The flexural members are inclined relative to an axis of the frame in a direction calculated to result in translated vibration substantially aligned with the lead angle of the thread being cut. Also disclosed is an automated system for applying different vibration patterns to the tap/workpiece interface during tapping and for recording the tapping torque associated with each vibration pattern. The disclosed system permits identification of the vibration frequency and amplitude that results in the greatest reduction in tapping torque. The automated system may be configured as an adaptive machine tool to first identify and then apply the optimum vibration pattern.

Abstract: A vacuum-hydrostatic shoe especially suited for supporting a workpiece in metalworking operations is disclosed. The vacuum-hydrostatic shoe is comprised of a body with a support surface confronting the workpiece. Preferably the support surface is shaped to substantially conform to the workpiece shape. The shoe body comprises hydrostatic pockets. Each hydrostatic pocket has a first pressure opening defined in the support surface and a second pressure opening fluidly connected to a respective first pressure opening. The second pressure openings are also fluidly connected to a supply of pressurized fluid so that a flow of pressurized fluid can be created between the shoe body and the workpiece. The shoe body further comprises a vacuum pocket. The vacuum pocket has a first vacuum opening defined in the support surface and a fluidly connected second vacuum opening. The second vacuum opening is also fluidly connected to a source of vacuum to create a vacuum pressure between the shoe body and workpiece.
