Traditional Chinese Medication (TCM) is created, including different types of traditional Chinese medication. Needle therapy, just as development, depends on the idea of a typical act of the year and the customary drug stocks in a wide reach sustenance therapy. It, for the most part, is utilized as a reciprocal and elective clinical medicine. Since it is based is consumed into the philosophical hypothesis. Impact of Chinese philosophical works by the greater part of five components and a similar likeness hypothesis microcosm of the universe is grounded.

Remote Supervising of Power Plant

With the fast growth of power plant, traditional communication protocol cannot meet the actual requirements. We have to find a way to deal with this situation. In this paper, we put forward an information model and a communication protocol for remote supervising of power plant. Based on our information model, a supervised object is the basic and the least unit of supervising information. A supervised object contains 6 elements. We developed a Supervising Information Library termed as SIL to manage and store supervised objects. The SIL employs an arborescence structure. A branch contains a group of supervised objects. And each leaf stores a single supervised object. We proposed a proprietary protocol, abbreviated as RSPPP at the application layer of communication protocols. RSPPP Protocol works in 4 operation modes. The message of RSPPP protocol includes three fields and is described by Abstract Syntax Notation One. TLV (Type, Length, and Value) method is used to encode message for transmission. In our system, an Acorn RISC Machine is used as the central processor. The μC/OS II is employed as operating system. Our system occupies a ROM space of about 920 bytes and a RAM space of about 710 bytes when running in AT91SAM9263.

A Cardholder Identification System Based on Face and Double-sided ID Information

In this paper, a cardholder identification system based on identity card (ID) and camera video was proposed. Firstly, we realize the double-sided image acquisition of ID card using Acorn RISC Machine(ARM) and Field-Programmable Gate Array (FPGA) with two Contact Image Sensor (CIS) and read the face image from the ID's built-in chip through radio frequency technology, and simultaneously capture the cardholder's face from USB camera video. Then a matching algorithm was used to compare the three faces: the segmented face image from ID double-sided image, the face image stored in built-in ID chip and the cardholder's face image captured from the camera video. Finally, based on the matching results, we can identify the authenticity of the ID and judge whether the cardholder is holding his own ID. Another advantage of our system is that we can print the collected double-sided ID images rapidly without manual flip and alignment. Many functions are combined into this system.

Maximum power point tracking for the permanent magnet synchronous generator‐based WECS by using the discrete‐time integral sliding mode controller with a chattering‐free reaching law

In this study, a single sensor-based maximum power point tracking (MPPT) algorithm is presented for permanent magnet synchronous generator-based wind energy conversion system (WECS). The MPPT method used in this study uses only the wind speed sensor to generate the reference point required for the maximum power. A discrete-time controller is proposed to bring the system to the reference point determined by the MPPT algorithm. The designed MPPT controller consisting of a new discrete-time reaching-law approach and a discrete-time integral sliding mode control (SMC). The designed discrete-time SMC-based controller is implemented by using an Acorn RISC Machine (ARM)-based LM4F120 microcontroller, and its performance is examined on a WECS emulator prepared in the laboratory. The results got from the real-time studies prove that the proposed controller has the satisfactory performance to bring the system to the MPP. The performance of the proposed controller is also compared with the conventional sliding mode controller and perturb and observe method. The obtained results proved that the proposed controller has a better performance than the other controllers in terms of the settling time and output voltage's ripple.
