An adaptive term implements by the wavelet neural network output to approximately cancel uncertainties, and also a robust term is designed to attenuate the approximation error with guaranteed performance and stability. The system asymptotically tracks the desired output by means of on-line studying uncertainties via wavelet neural network. Theoretical analysis is done to validate Lyapunov stability of the system. The simulation results show that the developed method can provide sufficient robustness and adaptability. This method is effective and deals with the problem of uncertain parameters preferably. ? 2011 IEEE.IEEE 2nd International Conference on Computing, Control and Industrial Engineering, CCIE 201120112332-336IEEE 2nd International Conference on Computing, Control and Industrial Engineering, CCIE 2011,2011,2:332-336On the appeal to the public from sustainable developmenthttp://ir.nwpu.edu.cn/AchivementDetails/Index/220711Liu, Mengcan,2019/6/28 15:56:42The concept of sustainable development reflects the common, fundamental needs and interests of the human, and the values of sustainable development can not put aside the interests of the human, so, the fundamental interests of mankind are the ultimate value of sustainable development. However, sustainable development with the overall interest of human and the fundamental interests as its ultimate values can hardly effectively implemented and achieved in existing framework of markets and governmental. Facing market failure and government failure, sustainable development calls for public active, broad and deep participation. ? 2011 IEEE.International Conference on Management and Service Science, MASS 20112011International Conference on Management and Service Science, MASS 2011,2011Integrative tactical decision-making of information-based Cooperative Air Combat with ameliorative Lanchester equationshttp://ir.nwpu.edu.cn/AchivementDetails/Index/220723Wan, Kaifang, Gao, Xiaoguang,2019/6/28 15:56:42Present a characteristic of systematic rivalry, modern combat under conditions of information presents a low applicability of the traditional Lanchester theory.

In the light of this, a new model based on the Real-time Queuing Theory is proposed for managing and scheduling the transmitting of information which reduces the messages occupying the queue resources without servicing on time and improves the network transmission efficiency. Then, a new index named message schedule service rate is presented to evaluate the performance of the network.

The results indicated that the mode was a carbon source if we comprehensively considered agricultural materials production subsystem and farming subsystem together, with the quantity of net GHGs being -1075.71kgCO2e when producing 1 ton of wheat and maize. But if only farming system was considered, the averaged quantity of cropland carbon sequestration was +262.31 kgCO2e, which could offset the -222.99 kgCO2e carbon emission caused by fertilizes and agricultural machine. Therefore, through straw return and tillage system improvement, farming system might become the carbon sink in the future. ? 2011 Published by Elsevier Ltd.2010 International Conference on Energy, Environment and Development, ICEED 201020115785-7922010 International Conference on Energy, Environment and Development, ICEED 2010,2011,5:785-792The sustainable development evaluation of energy and chemical engineering base of Northern Shaanxi regionhttp://ir.nwpu.edu.cn/AchivementDetails/Index/220735Xie, Wei, Zhao, Songzheng, Li, Jianzhong,2019/6/28 15:56:42The purpose of this article is to provide a systematic evaluation method to the sustainable development of energy and chemical engineering base of Northern Shaanxi region.

If special material substrate and add matching network are combined, which not only reduce the quality factor of antenna, but also produce maximum output power for little reflection of load. When the dielectric constant �� of special material substrate changes, the bandwidth of U-notch microstrip patch antennas is different. The impact of dielectric constant is discussed in detail. The S11 parameter of the antenna has been simulated by HFSS. The simulation results show that the lower dielectric constant can gain wider band of antenna. ? 2010 IEEE.2010 IEEE International Conference on Ultra-Wideband, ICUWB201020101135-1382010 IEEE International Conference on Ultra-Wideband, ICUWB2010,2010,1:135-138Reliability analysis of two kinds take-back models in reverse logisticshttp://ir.nwpu.edu.cn/AchivementDetails/Index/220771Zhang, Jing, Liang, Gongqian, Li, Hui,2019/6/28 15:56:42The complexity and high uncertainty of reverse logistics have brought great difficulties to the reasonable operation and decision-makings of each supply chain node.

However, fully labeled data streams are expensive to obtain, which makes the supervised learning approach difficult to be applied to real-life applications. In this paper, we consider the problem of one-class classification on data stream with respect to concept drift where a large volume of data arrives at a high speed and with change of concept. In this case, only a small number of positively labeled examples is available for training. We propose our OcEC(One-class Ensemble Classifiers)algorithm and have it compared with WEC[1] algorithm and SEA[2] algorithm. Experimental study on both Moving Hyperplane dataset and SEA dataset shows that the OcEC algorithm has excellent classification performance and can quickly adapt to concept drift. ? 2010 IEEE.2010 International Conference on Computer Application and System Modeling, ICCASM 201020102V2596-V26002010 International Conference on Computer Application and System Modeling, ICCASM 2010,2010,2:V2596-V2600Association analysis and case study framework based on the name distinctionhttp://ir.nwpu.edu.cn/AchivementDetails/Index/220779Wu, Bo, Cai, Wandong, Li, Yongjun,2019/6/28 15:56:42The research of distinction of name ambiguity in the field of information retrieval could enhance searching effect. Therefore, it plays an important role to mine the data of name ambiguity in order to obtain useful knowledge. In this paper, we focus on the problem of traditional evaluation and ranking method used in the clustering. Traditional evaluation and ranking method ignores the association among the sub-information and simply considers that pieces of sub-information are mutual independent. We present an effective data mining method framework based on the case study and association analysis. The method framework is evaluated on the dataset of name ambiguity from the database of CDBLP. The dataset includes the information of coauthor name, workplace, publication, years and ranking of the author of papers. The experimental results show that one piece of main sub-information assisted by some minors could form a stronger rule very useful for the distinction of name ambiguity. Also some combinations of pieces of minor sub-information could produce a stronger rule. The association rules selected by the experiment could be easily explained and commonsensible. Considering the association rules coming from the objective data and data mining method, they are more reliable.2010 International Conference on Computer Application and System Modeling, ICCASM 201020104V4285-V42892010 International Conference on Computer Application and System Modeling, ICCASM 2010,2010,4:V4285-V4289Classifying skewed data streams based on reusing datahttp://ir.nwpu.edu.cn/AchivementDetails/Index/220780Liu, Peng, Liu, Peng, Liu, Peng, et al. 2019/6/28 15:56:42Current research community on data streams mining focuses on mining balanced data streams.

In this paper, we introduce the method of discovering concept drifting on skewed data streams and propose an algorithm for c1assitying skewed data streams based on reusing data, RDFCSDS (Reuse Data for Classitying Skewed Data Streams). We evaluate RDFCSDS algorithm on Moving Hyperplane data set. The experiment results show that the sampling method based on reusing data works better than the simple sampling method and cluster sampling method on skewed data streams with concept drifting.2010 International Conference on Computer Application and System Modeling, ICCASM 201020104V490-V4932010 International Conference on Computer Application and System Modeling, ICCASM 2010,2010,4:V490-V493Application of particle swarm optimization for the design of a broadband microstrip antennahttp://ir.nwpu.edu.cn/AchivementDetails/Index/220781Zhao, Ya-Min, Xu, Jia-Dong,2019/6/28 15:56:42The discrete binary particle swarm optimization (PSO) is an extension of standard PSO on binary system. As a time-domain method, finite different time domain (FDTD) can obtain the required broadband frequency information through once time-domain calculation. Therefore, PSO's fitness function can choose multi-point in frequency, that is, the design of fitness function is more flexible when PSO is combining with FDTD. In this paper, discrete binary PSO combined with FDTD method is applied to design a broadband microstrip antenna. Test results show the bandwidth of the optimized antenna at -10dB is expanded significantly compared with the original antenna. ? 2010 IEEE.2010 International Conference on Computer Application and System Modeling, ICCASM 2010201015v15406-v154082010 International Conference on Computer Application and System Modeling, ICCASM 2010,2010,15:v15406-v15408A ciphertext retrieval model for encrypted XML database with bucket management algorithmhttp://ir.nwpu.edu.cn/AchivementDetails/Index/220785Lu, Xuan-Min, You, Jun, Zhou, Ya-Jian,2019/6/28 15:56:42To resolve the problems of security and ciphertext query efficiency for the XML database, a ciphertext retrieval model is presented in this paper.

The stub uniformly distributed along one of parallel double microstrip lines in the proposed routing method increase the mutual capacitance without much changing the mutual inductance between the aggressor and victim lines. This reduces the difference between the capacitive and inductive couplings and hence the far-end crosstalk. The structure of parallel double microstrip lines is treated as a symmetrical network with 4 ports, simulation on the S parameters is processed. Comparison with the no guard, the serpentine guard, and the via-stitch guard shows the proposed routing method gives the smallest values in the peak far-end crosstalk voltage and has a relatively simpler structure. ?2010 IEEE.2010 9th International Symposium on Antennas Propagation and EM Theory, ISAPE 20102010994-9972010 9th International Symposium on Antennas Propagation and EM Theory, ISAPE 2010,2010,994-997A novel design for UHF near-field RFID reader antenna based on traveling wavehttp://ir.nwpu.edu.cn/AchivementDetails/Index/220799Ren, Ankang, Wu, Changying, Wang, Ting, et al. 2019/6/28 15:56:42A novel planar antenna is presented for ultra high frequency (UHF) near-field radio frequency identification (RFID) applications. The antenna is composed of grounded coplanar waveguide, coplanar stripline, a lumped balun, multiple resistances and a finite-size ground plane. The load impedance is equal to the characteristic impedance of the coplanar stripline, so traveling wave can transmit along the coplanar stripline. The proposed structure can make large currents along the coplanar stripline so that a strong and uniform magnetic field distribution is excited in the region around the antenna. The antenna geometry, design concept, simulated and measured results are carefully discussed throughout the paper. Measurements show that the antenna operating with a commercial reader demonstrates good performance of tag identification with inductive coupling for near-field RFID applications. ? 2010 IEEE.2010 IEEE 12th International Conference on Communication Technology, ICCT'20102010239-2422010 IEEE 12th International Conference on Communication Technology, ICCT'2010,2010,239-242The relationship research between governance structure and company performance of energy listed companyhttp://ir.nwpu.edu.cn/AchivementDetails/Index/220800Chai, Huaqi, Song, Deqiang,2019/6/28 15:56:42Corporate governance structure is the most important structure in a modern enterprise system, whether reasonable or not is the most important decision factor for the business performance improving.

The method utilizes near-field data to determine equivalent sources over a fictitious surface which encompasses the target made by perfect electric conductor (PEC) and these sources are used to ascertain the far-field RCS. An electric field integral equation (EFIE) is developed to relate the near-field to the equivalent sources. RWG basis function is involved and makes the EFIE simple. The equivalent sources can be expanded by RWG basis function according to method of moments (MOM) procedure. The integral equation can be transformed into a matrix with the equivalent sources decoupling from the equation. The matrix equation is solved with the least squares techniques.

Wi-Fi is connected through SPI (Serial Peripheral Interface Bus) to form the relatively energy saving wireless transmission. Along with other interfaces, the multi-interface function requirements are satisfied. Firstly, the overall module design framework is introduced, followed by the hardware and software designs respectively. This project focuses on the node expansibility, taking TQ2440 as the base hardware platform, which is rich in interfaces with reserved extensive area. On the other hand, eCos is adopted to provide the real-time performance. After the drivers' implementation on eCos, which contain serial, flash, Ethernet and Wi-Fi, OLSR route protocol is ported to eCos as system route used in the data transmission course. Ultimately, nodes are deployed in AdHoc mode network for tests, which prove that the wireless data acquisition and transmission are available for the node construction. Meanwhile, the AdHoc mode can enhance the robustness of the network, reducing the network failure due to the router crashing in the central control network. It is believed that the node design realizes a prototype which can be used in most of the remote monitoring scene of WSNs. ? 2011 IEEE.2011 2nd International Conference on Artificial Intelligence, Management Science and Electronic Commerce, AIMSEC 201120113902-39052011 2nd International Conference on Artificial Intelligence, Management Science and Electronic Commerce, AIMSEC 2011,2011,3902-3905Architecture and real-time characteristics analysis of the cyber-physical systemhttp://ir.nwpu.edu.cn/AchivementDetails/Index/221146Zhang, Yuchen, Duan, Weijun, Wang, Fubao,2019/7/27 15:40:22Based on the current research development of CPS (Cyber-physical System) and the idea of the CPS systematic structure, this report focuses on the real-time feature of CPS and the task model.

The uncertainties are approximated by a set of adaptive fuzzy logic systems, with the adjusted parameters updated by a simplified recursive least squares estimation algorithm, combined with a state observer. For a constant known network-induced time-delay, the proposed modified dynamic surface control utilising the predicted system states, expands the acceptable network-induced time-delay and stable operating range for a discrete-time non-linear pure-feedback MIMO system in the network. The simulation results indicate that the presented method is effective. ? 2017, ? 2017 Informa UK Limited, trading as Taylor & Francis Group.International Journal of Control20199271707-1719International Journal of Control,2019,92(7):1707-1719CRISPR disruption of TCTP gene impaired normal development in the silkworm Bombyx morihttp://ir.nwpu.edu.cn/AchivementDetails/Index/1027599Liu, Zu-Lian, Xu, Jun, Ling, Lin, et al. 2019/7/13 15:40:20The translationally controlled tumor protein (TCTP) is a highly conserved and multifunctional protein with activities ranging from cytoskeletal regulation to transcription regulation in numerous organisms. In insects, TCTP is essential for cell growth and proliferation. Recently, TCTP has been reported to affect the innate intestinal immune pathway in the Bombyx mori silkworm, a lepidopteran model insect. However, the comprehensive physiological roles of TCTP in the silkworm remain poorly understood. Here, we performed functional analysis of BmTCTP by using a binary transgenic CRISPR/Cas9 (clustered regularly interspaced short palindromic repeat/RNA-guided CRISPER-associated protein 9 nucleases) system. Disruption of BmTCTP led to developmental arrestment and subsequent lethality in third instar larvae. Histological analysis revealed that growth impairment originated from decreased cell size, and the proliferation and differentiation of intestinal epithelial cells were also affected. RNA-seq analysis revealed that genes involved in carbohydrate metabolism, lipid metabolism and digestive system pathways were significantly affected by BmTCTP depletion. Together, the results demonstrated that BmTCTP plays a key role in controlling larval growth and development.INSECT SCIENCE2019266,SI973-982INSECT SCIENCE,2019,26(6,SI):973-982Optimization on GA-BP neural network of coal and gas outburst hazard predictionhttp://ir.nwpu.edu.cn/AchivementDetails/Index/1031667Wu, Bo, Wu, Shiyue, Liu, Xiaofeng,2019/6/28 15:56:42This paper presents a genetic algorithm and back propagation neural network (GA-BP-NN) outburst prediction model with a structure of 6 �� 13 �� 1 according to basic theory of coal and gas outburst hazard classification prediction of coal mine and genetic algorithm, back propagation and neural network.
