Abstract: A grid-forming wind turbine control method for a diode rectifier unit-based offshore wind power transmission system. A control system for controlling a grid-side converter has a three-layered structure, where a first layer is a combination of an active power controller and a reactive power controller; a second layer is a voltage controller; and a third layer is a current controller. The actual reactive power is represented by a per-unit value of a capacity of a corresponding wind turbine unit. The wind turbine units have the same reactive-power reference value, which is constant and does not change with time. The reactive power controllers of all wind turbine units have the same structure and parameters.

Abstract: One embodiment can provide a robotic system. The robotic system can include a robotic arm comprising an end-effector, a robotic controller configured to control movements of the robotic arm, and a dual-resolution computer-vision system. The dual-resolution computer-vision system can include a low-resolution three-dimensional (3D) camera module and a high-resolution 3D camera module. The low-resolution 3D camera module and the high-resolution 3D camera module can be arranged in such a way that a viewing region of the high-resolution 3D camera module is located inside a viewing region of the low-resolution 3D camera module, thereby allowing the dual-resolution computer-vision system to provide 3D visual information associated with the end-effector in two different resolutions when at least a portion of the end-effector enters the viewing region of the high-resolution camera module.

Abstract: Innovations in unified intra block copy (“BC”) and inter prediction modes are presented. In some example implementations, bitstream syntax, semantics of syntax elements and many coding/decoding processes for inter prediction mode are reused or slightly modified to enable intra BC prediction for blocks of a frame. For example, to provide intra BC prediction for a current block of a current picture, a motion compensation process applies a motion vector that indicates a displacement within the current picture, with the current picture being used as a reference picture for the motion compensation process. With this unification of syntax, semantics and coding/decoding processes, various coding/decoding tools designed for inter prediction mode, such as advanced motion vector prediction, merge mode and skip mode, can also be applied when intra BC prediction is used, which simplifies implementation of intra BC prediction.

Abstract: Methods of forming a settable resistance device, settable resistance devices, and neuromorphic computing devices include isotropically etching a stack of layers, the stack of layers having an insulator layer in contact with a conductor layer, to selectively form divots in exposed sidewalls of the conductor layer. The stack of layers is isotropically etched to selectively form divots in exposed sidewalls of the insulator layer, thereby forming a tip at an interface between the insulator layer and the conductor layer. A dielectric layer is formed over the stack of layers to cover the tip. An electrode is formed over the dielectric layer, such that the dielectric layer is between the electrode and the tip.
