Abstract: A method for preparing a high-performance difficult-to-deform metal precision seamless pipe includes steps of performing a heat treatment; drilling; externally grinding; internally grinding; straightening; performing four-roller warm-rolling; performing warm-drawing to reduce a diameter; performing warm-expansion to reduce a wall thickness and increase the diameter; performing precise cold-rolling; degreasing; brightening; performing surface grinding; cleaning dust; detecting flaws; testing metal structure performance; and sizing and packaging. By cycling the warm-drawing, the warm-expansion, and the precision cold-rolling, key indicators such as product dimensional accuracy, surface quality, material properties, and crystal grain size can be collaboratively controlled, to achieve higher accuracy, better performance, and more outstanding extreme specifications.

Abstract: A method for accessing a flash memory device and a flash memory device. After receiving a write request for an address, a flash memory controller obtains an indicator of the address, where the indicator indicates a last access type of the address, which might be a write operation or a read operation. When determining the indicator indicates a write operation, which means the access type for the address is normally write operation, to save time, the flash memory controller perform a fast-write operation on the address, when the indicator indicates a read operation, which means there might be plenty of read operations on the address, to facilitate future read operation, the controller performs a slow-write operation on the address.

Abstract: A method for processing a write request is disclosed, the method includes: determining, by an IO scheduler, that current IO scheduling is in a blocked state; selecting, by the IO scheduler, a target synchronous write request from to-be-processed IO requests; adding, by the IO scheduler, an acceleration flag to the target synchronous write request, where the acceleration flag is used to instruct a flash memory controller to perform acceleration processing on the target synchronous write request by using idle space of a flash memory; after the flash memory controller receives, from the IO scheduler, the target synchronous write request, determining, by the flash memory controller, a size of the idle space of the flash memory; and when the size of the idle space of the flash memory is greater than a threshold, performing, by the flash memory controller, acceleration processing on the target synchronous write request.

Abstract: A rotary driving mechanism includes a support stand, an air feeding assembly, and a driver. The air feeding assembly includes a bearing base, a rotating member, two first ventilating joints, and two second ventilating joints. The bearing base is coupled to the support stand and defines an inner circular surface. The rotating member is rotatably received in the bearing base and resists the inner circular surface. The rotating member defines two circular grooves at an outer periphery thereof and two channels therein. Each circular groove is in fluid communication with one of the channels. The first ventilating joints are coupled to the bearing base and respectively in fluid communication with the circular grooves. The second ventilating joints are coupled to the rotating member and respectively in communication with the channels. The driver is coupled to the rotating member and in communication with the second ventilating joints.

Abstract: Low energy consumptions are extremely important in real-time embedded systems. Due to the uncertainties in execution time of some tasks, this paper models each varied execution time as a probabilistic random variable and incorporating applications' performance requirements to explore real-time embedded systems and avoid over-designing them. We propose a practical algorithm to minimize the expected value of total energy consumption while satisfying the timing constraint with a guaranteed confidence probability. The experimental results show that our approach achieves significant energy saving than previous work. For example, our algorithm achieves an average improvement of 61.2% on total energy consumption compared with the algorithm in previous work.
