A broadband YIG tuned oscillator (YTO) frequency sweeping signal generator based on the DDS-PLL method is introduced. A linear sweep frequency sinusoidal signal generated by DDS is used to a reference signal of the YTO PLL (Phase-Locked Loop), and the other input of PLL is the linear frequency sweep signal of the YTO, the resulting error correction signal drives the YTO FM coil. Error correction signal can compensate the YTO nonlinear error, thereby ensuring that the YTO sweep signal generator output is accurate, linear frequency sweep signal. The signal generator module has been successfully applied to a spectrum analyzer.

Against the problem of extracting the color aberration of high-reflect-rate ceramic tile surface texture, author came up a way of using wavelet transformation to extract the image texture features. Basically, the way is suggesting using two dimension wavelet decomposition on each passage of the image and extract energy characteristic from each detailed sub-graph. This energy signal merges the message of color and feature. Calculate samples' color histogram statistics as the critical data for doing classification. In the end, using Minimum Distance Classifier to sort the samples. According to the experiment, compare the existing method which mostly using the color histogram distribution, this method can show better message of color distribution in space. Experiment shows that this method can get a better classify result.

In Zigbee network performance evaluation, there is artificiality to determine weights of Multi-dimensional indexes, and the indexes could not be completely independent. We combine the entropy method and correlation between indexes, and build multi-evaluation index weight decision analysis model to get more objective and realistic evaluation of indexes. Using opnet network simulation software, we collect different network performance parameters by changing the node size. The data analysis shows that the entropy can objectively and accurately reflect the size of information provided by each index, and this method can reflect the relative importance of each index more objectively and accurately.

Polarimetric scattering feature parameters are significant for target interpretation in polarimetric synthetic aperture radar (PolSAR) images. To improve the polarimetric scattering similarity parameters (PSS), an enhanced polarimetric similarity parameter (EPS) is proposed in this paper. Besides emphasizing some scattering mechanisms, this novel parameter improves the contrast between one certain scattering type and other scattering types. Furthermore, by employing the sparsity feature of the enhanced span image, nonnegative matrix factorization (NMF) is modified to realize the urban area detection for PolSAR images. The effectiveness of this proposal is verified by real data experiments.

In the agricultural production, recently there are some problems in the determination of the amount of soil nitrate nitrogen using ion selective electrode such as low accuracy and long detection time. The research on measurement model of soil nitrate nitrogen based on ion selective electrode is carried out in this article aiming to obtain the information of soil nitrate nitrogen quickly and accurately. Simple linear regression equation is adopted to establish the calibration equation of ion selective electrode and the calculated values of this model compared with laboratory measurements show that the model is quite accurate. Then "stepwise fitting method" is used to establish the three-dimensional mathematical model which also has wide application values among the concentration of test solution, the measuring potential of ion selective electrode and the temperature of test solution.

In this paper, according to the refractive index of magnetic fluid variation relationship with temperature, the transmission characteristics of photonic crystal fiber (PCF) filled with the magnetic fluid (MF) were simulated and analyzed using the full-vector finite element method. The major researches were numerical simulation about the temperature affects on the mode field, transmission mode, the effective refractive index and loss of different air hole diameter PCF filled with MF under different wavelengths. The results show that the wavelength, the air hole diameter and the temperature have impacts on the transmission characteristics of the PCF filled with MF. And the longer the wavelength, the larger the diameter of the air hole, the transmission characteristic of the PCF is more significantly affected by temperature. When the temperature change from 20 to 80°C under the input wavelength at 1550nm, the PCF with the air hole diameter of d = 4.5μm, hole spacing Λ=5.6μm maintain the single-mode transmission, the effective refractive index decreases from 1.442451 to 1.441154, the effective mode area reduces from 32.333087μm2 to 28.276072μm2, and the confine loss increases from 37.553468dB/m to 38.103598dB/m (corresponding to the temperature of 25°C), and then decrease linearly to 27.501534dB/m.These characteristics provide the theoretical basis for the temperature controlling light field, and provide new methods, new ideas for temperature measurement and the reference for the design and applications of temperature modulation device based on PCF.

This paper focuses on the introduction of a fast and high precision harmonic analysis algorithm used for power energy measurement. The derivation process of a novel approach to harmonic analysis for industrial power systems based on windowed fast Fourier transform is presented. And the formulas of the concerned harmonic parameters, i.e., frequency, phase, and amplitude, are given also, which is free of calculating high-order equations. The proposed algorithm has the major characters that the accuracy is comparable to the currently used polynomial fitting interpolation algorithm, but the calculation speed is improved by more than 10% and can be easily implemented by hardware multipliers, making the method a good choice for real-time applications. The simulation results and application in the embedded computer STM32F407 based three-phase harmonic power energy meter validated the practicability and efficiency of the proposed algorithm.
