This paper proposes a relational aggregation algorithm based on Radio Frequency Identification (RFID) to achieve accurate indoor localization. The proposed algorithm is composed of three steps: (1) exploring the relationship between reader received power and distance information then estimating Euclid distance of signal strength; (2) employing k-Nearest Neighbour algorithm to aggregate the relationship...
Alternating current (AC) machine speed-adjusting system plays a very important role in our daily life. Firstly, this paper studies the basic principle of vector control system for three-phase asynchronous motor based on the MT coordinate system, and this paper especially gives the calculation principle diagram of the current model for rotor flux. Then this paper establishes the double closed-loop...
Based on the research on the least square influential coefficient method of rotor dynamic balance, to deal with some problems like excessive residual vibration and unsatisfied balance effect, genetic algorithm was introduced to optimize and realize the least square influential coefficient method by using the characteristic of global optimization search. Experimental result shows that the balance algorithm...
This paper first analyzes the mathematical model of mobile Ad Hoc networks by considering a weighted value of the ratio between sustainable energy and the total consumed energy of nodes in order to find a balance point between them. And it proposes a solution to the problem of energy efficient and load balance. Finally it presents some improvement suggestions to the AODV protocol.
In this paper, the artificial neural network (ANN) algorithm for solving system of linear equations is considered and the algorithm convergence theorem is derived. Some numerical tests are given to demonstrate the effectiveness of our results.
Unlike the central banks in the western countries, the Chinese central bank controls the term structures of bank deposit interest rates, and lending interest rates. They are called as official interest rates in the paper. Heavily affected by these official rates, market interest rates in the bond market behave in a unique way. Theoretical model and empirical study indicate that changes of official...
