Designing a sparse array with reduced transmit/receive modules (TRMs) is vital for some applications where the antenna system's size, weight, allowed operating space, and cost are limited. Sparse arrays exhibit distinct architectures, roughly classif

A microwave-induced thermoacoustic imaging (MITAT) system is a non-destructive physical medical imaging method that combines the advantages of the high contrast of microwave imaging and the high resolution of ultrasound imaging. It uses the microwave

The direction-of-arrival (DOA) estimation problem can be solved by the methods based on sparse Bayesian learning (SBL). To assure the accuracy, SBL needs massive amounts of snapshots which may lead to a huge computational workload. In order to reduce

A new stochastic nonlocal denoising method based on adaptive patch-size is presented. The quality of restored image is improved by choosing the optimal nonlocal similar patch-size for each site of image individually. The method contains two phase. Th

In this study, based on the predicted secondary structures of proteins, we propose a new approach to predict protein structural classes (α,β,α/β,α+β) for three widely used low-homology data sets. Fist, we obtain two time siries from the chaos g

The non-local means (NLM) has been becoming a prevalent method in image denoising. However, the denoised performance of this method depends heavily on the accuracy of similarity measure. In this paper, we present kernelized $L^{2}$-norm to measure th

Sparse signal representation (SSR) based methods proposed in recent years could realize high resolution DOA estimation. However, when the aperture of array is small, the mainlobe of radiation pattern of the array will be wide which leads to a deterio
