In order to detect foreign body from the complex channel background and cotton layers, a detection method based on RGB space model is presented in this paper. The feature of the standard cotton and the channel background was extract to create a space model of cotton. And then this model was used to process the 24-bit true color images which were captured from a foreign body picking equipment. Simulation...

In this paper, a modified TS-type neuro-fuzzy system (MTSNFS) for on-line identification is proposed, which possesses six layers of neurons to perform the fuzzy inference. A modified self-organizing competitive learning algorithm with capabilities of dynamical rules recruitment and cancellation is proposed for structure identification. A hybrid learning algorithm combining recursive least squares...
C2C is an important part of E-commerce, even in the economic crisis it is still rapidly growing. However, compared with the traditional economy, the research on the network economy is still in its infancy. So this paper aims to C2C market to find consumer behavior rules. Differential pricing exists in C2C market, too. But the main reason is the uncertainty of product quality. Because different kinds...

The article analyzes the influences of carbon tax on Chinese economy by constructing a dynamic recursive general equilibrium model. The simulation results show that carbon tax will make negative impacts on the economic growth in the short term. However, it will greatly reduce carbon emissions and meanwhile stimulate economic development in the long term.
A reconfigurable flight control based on a single hidden layer perception (SHL) neural network (NN) for adaptive compensation of dynamic inversion for the Unmanned Aerial Vehicle (UAV) with multiple control effectors is described. This approach has not to depend on failure identification and isolation. The basic control law is designed by nonlinear dynamic inversion, and SHL neural networks are used...

It is the purpose in this paper to determine the shape of the snowboard course, A mechanical model of snowboarding is proposed by analyzing the force at every point. The gradient of transition area and the depth of half-pipe are considered as two main factors in the model. at last, we solve and simulate it by Matlab.
Model of compliance behavior is built based on system dynamics and safety management theory. Effects of different safety management measures on compliance behavior are simulated with production pressure. The simulation results show that management safety enforcement is not effective on safety alone with higher production pressure. Safety priority is the most effective policy and accident learning...
Railway, as one of the most essential infrastructures of China, has endured extremely high difficulty level due to huge investment scale and high quality requirements. The traditional management method of technical-economic indexes and simulation are not perfect, so simulating technical indexes catering to the features of railway construction project is an accurate and efficient management method...
With the wide use of digital manufacture technology, the airplane digital assembly based on the examples can better solve these problems, such as the concurrent design of complex products, the assembly sequence, and the man -machine relationship, etc. This can also improve the quality of assembly and make maintenance more accurate and convenient. The research presents a design method of a certain...
A trapezoidal waveform is usually used instead of the actual back EMF in numerous research literatures on simulation of brushless DC (BLDC) motors, which causes the errors to the simulation and calculation of the motor. This paper adopts the flux linkage changing rate matrixes of the permanent magnets to calculate the back EMF, establishes the mathematical model of a 30 kW six-phase BLDC motor based...
Faced with the challenges of increasing operational frequencies and switching rates of modern electronics devices used in electrical systems, there is an extensive need for high frequency models (up to a few gigahertz) for electrical components like bandpass filters, couplers and power distributors. This paper presents the application of partial element equivalent circuit (PEEC) theory for the creation...

Aiming at the features of moving small target in infrared sequence dynamic image, this paper presents a small target detection method based on morphology and wavelet transform. Firstly, the image is preprocessed using top-hat transformation to suppress most of the background clutter and enhance the target. Secondly, the image is decomposed by using single-scale wavelet transform and the high frequency...
Surface texture feature has an important influence on the use of parts performance. Because of cutting parameters and tool path changing, different shapes of texture are formed on surface of machined workpiece by tangential turn-milling. Surface texture of workpiece is studied from scallop height and constructed function, simulated by Matlab. It is shown that the texture height and spacing both increase...
