According to the trend of the intelligent monitoring system, on the basis of the study of gait recognition algorithm, the intelligent monitoring system is designed based on FPGA and DSP; On the one hand, FPGA’s flexibility and fast parallel processing algorithms when designing can be both used to avoid that circuit can not be modified after designed; On the other hand, the advantage of processing the digital signal of DSP is fully taken. In the feature extraction and recognition, Zernike moment is selected, at the same time the system uses the nearest neighbor classification method which is more mature and has good real-time performance. Experiments show that the system has high recognition rate.

Ni-CeO2nanocomposites were electrodeposited using rotating cylindrical cathode in ultrasonic field. The surface morphologies and the CeO2contents in the nanocomposite were examined by the Scanning Electron Microscopy and the Energy Disperse Spectroscopy. The microhardness of nanocomposites were also evaluated by digital microscopical Weis Sclerometer. The effect of ultrasonic power and cathode rotating speed on the CeO2nanoparticles contents and the distribution condition of the nanocomposites were investigated.

And the surface morphologies of nanocomposite coating showed better smooth surface, finer grain and more compact microstructure.

Controlled permeability formwork liner (CPFL) is the functional material similar to nonwoven fabrics and its filtration and drainage performance is dominated by the pore size distribution (PSD) of matrix. In this paper, suction table method, generally used to measure soil pore diameter, is improved for testing PSD of CPFL and experimental data was compared to the results from four other normal experimental methods, i.e., wet sieving method, bubble point method, mercury intrusion porosimetry (MIP) method and image analysis. The comparison indicates that PSD of CPFL obtained from suction table show good accuracy and repeatability. Furthermore, a modified mathematical model derived from Rawal model and Fature model is proved to be suitable for determinating PSD of the matrix of CPFLwith bilayer structure, and have a good agreement with the experimental data from suction table.

Interactions between civilizations and ethnic groups have generated a fusion of customs and lifestyles, with an important effect on plant genetic diversity. The loss of local species and varieties usually results in irreversible loss of the genetic diversity they contain, this has dangerously shrunk the genetic pool that is available for natural selection and art selection, and has consequently increased the vulnerability of agricultural crops to sudden changes in climate, and to the appearance of new pests. Currently, biotechnology and genomic selection have enabled the genetic alteration of crops, improved soil productivity, and enhanced weed and pest control, and benefit to the development of plant genetic diversity. For example, next generation sequencing (NGS) and bioinformatics, as the gold standard, they provide a powerful tool for discovery of domestication genes in crop plants and their wild relatives.The objectives of this article are to review the development of plant genetic diversity and summarize the research of biotechnology and genomics for plant. Then, we look forward and consider the significant of development of plant genetic diversity by biotechnology and genomics.

This paper focuses on the pore structure parameters of mortars produced with manufactured sand and natural sand via water saturation and MIP methods. Test results show that, total porosity, as well as compressive strength, of manufactured sand mortar, is higher than that of natural sand mortar at fixed w/c and s/c ratio. Furthermore, considerable volume of large pores present in specimens of manufactured sand at higher w/c ratio rather not at the lower w/c ratio, which caused by the larger binder-aggregate interface. Manufactured fine aggregate in mortar probably accelerate hydrated reaction of cement, which result in the most probable pore size is finer than that of natural sand mortar. It can be concluded that the threshold region becomes flatten and threshold radius increases due to the aggregate volume concentration rises. Finally, a new theoretical model with a double-lognormal distribution function is demonstrated to be reasonable to fit pore size distribution in mortars.

The contradictions between unreasonable terminal aircraft flight separation and rapidly increasing air traffic are prominent.

At present, the design of web-based courseware in distance education is too conservative and lack of innovation, which is mainly due to two reasons: One is the thinking set of courseware designers who are still possessing the mindset of education changes itself, which limits their thought into the field of education; The other one is the designer technical limitations that they are lack of technical skills of other related areas. Through introducing the thought and technologies of movie and virtual reality into education, we try to explore new designs for network courseware.

A single-carrier hole-only device of ITO/MoO3/NPB/Al was used to measure the hole mobility of NPB layer, where NPB is a hole transport material. The hole mobility of NPB at different electric fields was obtained from the hole transit time (τdc) which was extracted from the negative differential susceptance (ΔB) as a function of frequency. To eliminate the impact of the contact resistance on the mobility measurement, an equivalent circuit model has been introduced to calculate the capacitance and the conductance of the NPB layer. By fitting the Nyquist plot of the impedance spectroscopy using the equivalent circuit, the contact resistance can be extracted from the impedance measurements. It is found that the mobility at low electric field is lower than what was reported in literature after the consideration of the contact resistance. It is also found that the calculated hole mobility of the NPB layer follows the Poole-Frenkels rule.

on the basis of the measurement of ecological parameters by using remote sensing technology, combined with ecological method and Landsat–7 ETM +, we made a quantitative measurement of ecological assets of Sanjiang Plain in 2010, got the spatial distribution of ecological assets. The results show that: the value of ecological assets in Sanjiang Plain was 2.35 × 1012 yuan. The value was generally higher in the southern and lower in the northern parts of the study area. Baoqing has the highest sum value and Youyi has the lowest value than other areas. Forestlands have higher value of ecological assets than other land use types. Land use type may be the mainly reason for the spatial difference of ecological assets in Sanjiang Plain.

The traditional process of thesis evaluation is of subjectivity and differences of teachers’ qualifications and backgrounds. Considering these characteristics, this paper proposes a multi-level theses evaluation model based on fuzzy cluster analysis with the idea of fuzzy mathematics. In this model, it evaluates the teachers’ qualification first to determine the weight of various teachers’ evaluation to the thesis; then stratifies theses evaluation indicators, and according to the results of various indicators, it builds a fuzzy equivalent matrix, and ultimately selects the appropriate similarity coefficient to divide the theses into excellent, good, moderate, bad four grades. This model greatly improves the scientificalness and objectivity of the traditional theses evaluation process and provides a reference for the process.

Based on the principle that the same class is adjacent, an anomaly intrusion detection method based on K-means and Support Vector Machine (SVM) is presented. In order to overcome the disadvantage that k-means algorithm requires initializing parameters, this paper proposes an improved K-means algorithm with a strategy of adjustable parameters. According to the location of wireless sensor networks (WSN), we can obtain clustering results by applying improved K-means algorithm to WSN, and then SVM algorithm is applied to different clusters for anomaly intrusion detection. Simulation results show that the proposed method can detect abnormal behaviors efficiently and has high detection rate and low false positive rate than the current typical intrusion detection schemes of WSN.
