Intelligent Contract for Power Market Transaction Based on the BlockChain

Abstract: The power market is changing with the development of distributed energy. The development of the micro-grid introduces a small power generation system for distributed energy. It has become a trend for the micro-grid to participate in the power market. Blockchain is a database technology with transparent distribution through a decentralization mechanism. In the blockchain, the transaction data are maintained by entire nodes in the power market. It solves the trust problem between the transaction agents. Intelligent contract technology can make transaction contracts computerized and executed automatically, which has dramatically improved transaction efficiency. In this paper, an intelligent contract for the power transaction is analyzed based on the concepts of the blockchain. The roles of the micro-grid and the related intelligent contract technologies in the power market are also investigated in the electricity reform. Finally, a blockchain scheme for point-to-point trading is designed for future purposes.

Study of non-contact power transmission mechanism for unmanned underwater vehicle applications

Abstract: A permanent magnetic coupling is investigated for unmanned underwater application. In this paper, face to face magnetically coupled thruster is developed to transfer torque between driver (motor) and driven (propeller) shaft. Permanent cylindrical magnets are mounted on the faces of couplings for power transmission. Comparison of torque transmitted at different air gaps with equal numbers of magnets is presented. The number of magnets is same but center to center distance between magnets and coupling is different in all the designs. The working prototype successfully demonstrates non-contact power transmission from the driven to the drive shaft without compromising on the desired thrust rating.

Classification of non conformally flat cylindrically symmetric non static space-times according to their proper conformal motions

Abstract: In this paper we considered the most general form of non conformally flat cylindrically symmetric non-static space-times to study proper conformal motions using direct integration technique. We have shown that very special classes for cylindrically symmetric space-times admit proper conformal motions. This classification also covers non-static and static plane symmetric space-times. In [9] it was claimed that non conformally flat plane symmetric static space-times do not admit proper conformal motion. Here it is also shown that static and non static plane symmetric space-times admit proper conformal motions. We also discuss the Lie algebra in each case.
