A novel adaptive critic design (ACD) guaranteeing presented performance is addressed for hypersonic vehicles (HVs). In the previous studies, most ACDs focus on affine systems while ACD-based nonaffine tracking control rare. this paper, we propose a direct method HVs utilizing ACD. Within framework of ACD, fuzzy wavelet neural networks (FWNNs) are applied to build action and networks. Via an analytically invertible model approach, controllers developed, based which together with FWNN...

In this paper, we propose a generalized co-prime multiple-input multiple-output (MIMO) configuration for direction of arrival estimation. Compared with the conventional coprime MIMO radar that requires prototype arrays transmitter and receiver, proposed enlarges inter-element spacing an integer expansion factor. By vectorizing sample covariance matrix, sum difference coarray (GSDC) concept is defined exploiting advantages configuration. The analytical expressions factor, maximum consecutive...

The content of flavonoids and phenolic acids in the extract bamboo leaves (EBL) was determined using near-infrared spectroscopy. Optimal partial least squares models squares-support vector machine were developed to enable rapid non-destructive validation based on EBL contents as by photocolorimetric methods high performance liquid chromatography. performed slightly better than models. For models, correlation coefficients (R) root mean square errors (RMSE) calibration R(cal)= 0.9998,...

In this paper, we propose a computationally efficient spatial differencing matrix set (SDMS) method for two-dimensional direction of arrival (2D DOA) estimation with uniform rectangular arrays (URAs) in low-grazing angle (LGA) condition. By rearranging the auto-correlation and cross-correlation matrices turn among different subarrays, SDMS can estimate two parameters independently one-dimensional (1D) subspace-based techniques, where only perform difference are kept completely. Then,...

Motivation: While fMRI infers neural activity from hemodynamic changes, the relationship between two remains to be further clarified. Simultaneous electrophysiological recordings (Ephy) and can provide additional insights into neurovascular coupling brain function. Goal(s): Our objective is address electromagnetic interference (EMI) noise in simultaneous Ephy recording. Approach: A deep learning-based fully convolutional network (FCNN) was proposed effectively eliminate EMI noise. Simulated...

Multipath effect cause serious performance degradation in low-altitude target detection. To overcome the negative multipath a environment, novel weighted detector based on estimated signal-to-noise ratio (ESNR) is proposed. By introducing intensity factor, signal models for different radar systems environment are established. Then, inspired by recent development of cognitive theory, ESNR proposed to strengthen high SNR channels and suppress low channels. The eigenfunction method adopted...

The title compound, C9H12BrNO4S·H2O, was prepared by a reduced condensation reaction of 5-bromo-2-hydroxy­benzaldehyde and 2-amino­ethanesulfonic acid. In the crystal structure, two-dimensional network is formed via inter­molecular N—H⋯O O—H⋯O hydrogen bonds.

Abstract SrTiO3-based heterostructures have attracted much attention due to the abundant properties compared single components. Here, we fabricate oxide heterostructure of layed perovskite/perovskite Sr n +1 Ti O 3 /SrTiO and investigate value-dependent thickness-dependent conductivity. X-ray diffraction peaks reflective high energy electron indicate good film quality. For films =6, are conductive, conductivity is better for thicker film. On contrary, with =1, 2, 3, 4, ∞ insulating....
