Abstract: The present disclosure relates to systems, methods, and non-transitory computer-readable media that modify digital images via multi-layered scene completion techniques facilitated by artificial intelligence. For instance, in some embodiments, the disclosed systems receive a digital image portraying a first object and a second object against a background, where the first object occludes a portion of the second object. Additionally, the disclosed systems pre-process the digital image to generate a first content fill for the portion of the second object occluded by the first object and a second content fill for a portion of the background occluded by the second object. After pre-processing, the disclosed systems detect one or more user interactions to move or delete the first object from the digital image. The disclosed systems further modify the digital image by moving or deleting the first object and exposing the first content fill for the portion of the second object.

Abstract: A sheath facilitating retraction of prosthetic implant is provided. The sheath includes a tubular body, and the distal end of the body is connected with an expandable section. The expandable section has relative converged configuration and flared configuration and includes a primary expandable area and a secondary expandable area. The primary expandable area includes a plurality of first expandable pieces arranged at intervals in a circumferential direction of the body. The secondary expandable area includes a plurality of second expandable pieces arranged at intervals in the circumferential direction of the body, and all the second expandable pieces include two alternating groups consisting of a first group formed by further extending the first expandable pieces to the distal end and a second group formed by connecting strips wound between two adjacent first expandable pieces.

Abstract: A switching type control method based on a double loop predictive control is provided. A deadbeat control is adopted by the outer loop control. The switching type control method is adopted by the inner loop control. When the system is in the steady state, the deadbeat control by an inner loop is adopted to ensure the steady state accuracy of the system and to achieve the fixed switching frequency. When the system is in the transient state, it is switched to the finite control set model predictive control by the inner loop to ensure the rapid transition of the system to the steady state.

Abstract: The present invention discloses a switching type control method based on double loop predictive control, which belongs to the field of power electronic converter technology and industrial control. The invention is based on double loop predictive control, and the deadbeat control is adopted by the outer loop control to improve the overall performance of the system (the system refers to the implementation object of the control method, and generally refers the power electronic converter); a switching type control method is adopted by the inner loop control: when the system is in the steady state, the deadbeat control is adopted to ensure the steady state accuracy of the system and to achieve the fixed switching frequency; when the system is in the transient state, it is switched to the finite control set model predictive control to ensure the rapid transition of the system to the steady state.

Abstract: A test method includes selecting at least one agent included in a selected network based on network information input from a user, the selected network corresponding to the network information; receiving target server information; verifying whether a server corresponding to the target server information is present in the selected network based on the network information and the target server information; and transferring the target server information to the selected at least one agent.

Abstract: The present invention discloses a hybrid transformation system based on three-phase voltage type PWM rectifier and multi-unit uncontrolled rectifier. The hybrid transformation system mainly consists of a three-phase reactor (L), a three-phase voltage type PWM rectifier module, an N-unit three-phase uncontrolled rectifier bridge module group, capacitors (C0-CN) and a DSP control circuit. An input end of the three-phase voltage type PWM rectifier module is in parallel connection with an input end of each three-phase uncontrolled rectifier bridge module. The three-phase voltage type PWM rectifier module may work in to situations, with load or without load, and the three-phase voltage type PWM rectifier module just does reactive power compensation when working without load. All modules of the three-phase uncontrolled rectifier bridge module group may work in to situations, with loads independently or all the outputs are in parallel connection and with a same load.
