2Single-trial EEG classification using in-phase average for brain-computer interface显示文摘Communication signals should be estimated by a single trial in a brain-computer interface.Since the relativity of visual evoked potentials from different sites should be stronger than those of the spontaneous electro-encephalogram(EEG),this paper adopted the time-lock averaged signals from multi-channels as features.200 trials of EEG recordings evoked by target or non-target stimuli were classified by the support vector machine(SVM).Results show that a classification accuracy of higher than 97%can be obtained by merely using the 250–550 ms time section of the averaged signals with channel Cz and Pz as features.It suggests that a possible approach to boost communication speed and simplify the designation of the brain-computer interface(BCI)system is worthy of an attempt in this way.Jin’an GUAN Yaguang CHEN 2008Frontiers of Electrical and Electronic Engineering in China2008,3,2:1
3The Core and Coritivity off a System (IV)——Relations between a System and Its Complement显示文摘The coritivity, h(G), of a connected graph G, is defined by h(G) = max{ω(G-S)-|S|: S∈C(G)}, where ω(G) denotes the number of components of a graph G, C(G) denotes the collection of cut-sets of G. In this paper, the notion of complementary coritivity is proposed, and the relations between coritivity and its complement are studied, for example, two bounds, Nordaus-Gaddum problems and some foundational properties etc.Wang Yingluo, Xu Jin and Xi YouminManagement School, Xi’an Jiaotong University, Xi’an 710049, China 1993Journal of Systems Engineering and Electronics1993,4,2:4

14T-Shaped Transmission Line Fault Location Based on Phase-Angle Jump Checking显示文摘In order to effectively solve the dead-zone and low-precision of T-shaped transmission line fault location,a new T-shaped transmission line fault location algorithm based on phase-angle jump checking is proposed in this paper.Firstly,the 3-terminal synchronous fundamental positive sequence voltage and current phasors are extracted and substituted into the fault branch distance function to realize the selection of fault branch when the fault occurs;Secondly,use the condition of the fundamental positive sequence voltage phasor at the fault point is equal to calculate all roots(including real root and virtual roots);Finally,the phase-angle jump check function is used for checking calculation,and then the only real root can be determined as the actual fault distance,thereby achieving the purpose of high-precision fault location.MATLAB simulation results show that the proposed new algorithm is feasible and effective with high fault location accuracy and good versatility.Jia’an Xie YurongWang Guobin Jin Mucheng Wu 2022Energy Engineering2022,119,5:0

17STUDY OF THE MATHEMATICAL MODEL FOR RIVER CLOSURE USING BI-EMBANKMENT显示文摘This paper is concerned with a mathematical model for river closure using two embankments. Some novel techniques of computational fluid dynamics and the two equation (k-ε)turbulent model are used to solve the shallow water equations in curvilinear coordinates; and the technique of moving boundary is used to deal with the river bed exposed to water surface. Comparison between computed and experimental data shows a satisfactory agreement. The mathematical model can be employed to accurately simulate the characteristics for the studied flows and could find more applications in hydraulic engineering.Wei Wen-liXi’an University of Technology , Xi’an 710048, P.

19Stacked spectral feature space patch: An advanced spectral representation for precise crop classification based on convolutional neural network显示文摘Spectral and spatial features in remotely sensed data play an irreplaceable role in classifying crop types for precision agriculture. Despite the thriving establishment of the handcrafted features, designing or selecting such features valid for specific crop types requires prior knowledge and thus remains an open challenge. Convolutional neural networks(CNNs) can effectively overcome this issue with their advanced ability to generate high-level features automatically but are still inadequate in mining spectral features compared to mining spatial features. This study proposed an enhanced spectral feature called Stacked Spectral Feature Space Patch(SSFSP) for CNN-based crop classification. SSFSP is a stack of twodimensional(2 D) gridded spectral feature images that record various crop types’ spatial and intensity distribution characteristics in a 2 D feature space consisting of two spectral bands. SSFSP can be input into2 D-CNNs to support the simultaneous mining of spectral and spatial features, as the spectral features are successfully converted to 2 D images that can be processed by CNN. We tested the performance of SSFSP by using it as the input to seven CNN models and one multilayer perceptron model for crop type classification compared to using conventional spectral features as input. Using high spatial resolution hyperspectral datasets at three sites, the comparative study demonstrated that SSFSP outperforms conventional spectral features regarding classification accuracy, robustness, and training efficiency. The theoretical analysis summarizes three reasons for its excellent performance. First, SSFSP mines the spectral interrelationship with feature generality, which reduces the required number of training samples.Second, the intra-class variance can be largely reduced by grid partitioning. Third, SSFSP is a highly sparse feature, which reduces the dependence on the CNN model structure and enables early and fast convergence in model training. In conclusion, SSFSP has great potential for practical crop classification in precision agriculture.Hui Chen Yue’an Qiu Dameng Yin Jin Chen Xuehong Chen Shuaijun Liu Licong Liu 2022The Crop Journal2022,10,5:1
