The imitation bat detection system, which is according to principles of bat binaural echolocation, is made up of a imitation bat mouth, two imitation bat ears and a central controller. One of the key problems in the central controller, which make decisions with adaptive environment, is how to establish effective localization methods. To realize the rapid and effective localization, the information...
In the urbanization process of Guangzhou, which was characterized by highly centered economy and fast utilized resources, groundwater environment was influenced severely. High concentration of NO2- and NH4+ in groundwater concentrated in the city center, and samples with over proof NO3- distributed around the city and hilly areas, besides in the central region. Groundwater contaminations caused by...
The problem of uniform for the existing preference information in multi-attribute group decision making is discussed in this paper. A method is proposed based on the λ-cut of fuzzy mathematics to convert triangular fuzzy numbers and trapezoidal fuzzy numbers to interval number complementary judgment matrix. Means of converting interval-valued intuitionistic fuzzy judgment matrix and linguistic...
In this paper, a tracking algorithm with NLOS (non-line of sight) errors for MS (mobile station) in cellular networks is proposed. Initial evaluation of MS location is obtained by TDOA location method based on BP neural network. A Kalman filter is used to modify the initial evaluation of MS location and track the location with detection thresholds. Simulation result shows that the tracking algorithm...
BP (Back-propagation) neural network and conventional PID (Piping and Instrument Diagram) control combined. A PID control strategy of self-adjusting parameter brought forward. It solved the problems of the parameter certain complex and large computational quantity and realizes online adjustment PID parameters. According to control characteristic of PH value adjustment links in sewage treatment system,...
In this paper, we construct a neural network iteration method for simultaneous extraction of all roots of algebraic polynomial with variable learning rate. Its convergence was researched. The specific examples showed that the proposed method can simultaneously find all roots of algebraic polynomial at a very rapid convergence and very high accuracy with less computation.
As one of the renewable energy, the absorption and utilization of wave energy is always an important research field home and abroad, and energy absorption efficiency is the key. A wave energy absorption system based on inertial pendulum is presented, and dynamics equations are established. Artificial Neural network with learning rate adaptation is adopted to model in time domain. The results obtained...
In this research, the artificial intelligent method based human motion pattern recognition for surface electromyographic (EMG) signal is proposed. As the EMG signal is a measurement of anatomical and physiological characteristic of the given muscle, the macroscopical movement patterns of the human body can be classified and recognized. By using the technology of wavelet packet transformation, the...
