In this article, a channel micro-Doppler ( $\mu \text{D}$ ) signatures’ quantitative evaluation method for multiple-input–multiple-output (MIMO) radar system, named relative signal–noise ratio in the time–frequency domain and denoted as RSNRt

PageRank is a widespread model for analysing the relative relevance of nodes within large graphs arising in several applications. In the current paper, we present a cost-effective Hessenberg-type method built upon the Hessenberg process for the solut

The PageRank model computes the stationary distribution of a Markov random walk on the linking structure of a network, and it uses the values within to represent the importance or centrality of each node. This model is first proposed by Google for ra

PageRank problem is the cornerstone of Google search engine and is usually stated as solving a huge linear system. Moreover, when the damping factor approaches 1, the spectrum properties of this system deteriorate rapidly and this system becomes diff

For computing PageRank problems, a Power–Arnoldi algorithm is presented by periodically knitting the power method together with the thick restarted Arnoldi algorithm. In this paper, by using the power method with the extrapolation process based on

In this paper, we present a new algorithm by combining the cheap but slow power method with the fast but expensive Arnoldi procedure periodically. The main feature of our method is that a weighted inner product is introduced when using an Arnoldi pro

Computing PageRank plays an important part in determining the importance of Web pages. Based on the classical power method and the inner-outer iteration proposed by Gleich etźal. (2010), Gu etźal. (2015) presented a two-step splitting iteration, i.

The time-delay estimation (TDE) arises in many applications, especially in radar signal processing. In this study, different TDE techniques are considered based on well-known approaches such as classical matched filter, multiple signal classification

In order to improve the accuracy of fault diagnosis of power transformer in the presence of missing values, we propose a missing value imputation method by iterative k nearest neighbor (KNN), and ensemble learning is used to diagnose the power transf

In Web link structures, similar link distributions often occur, especially for pages from same hosts. For PageRank problems, similar in-link distributions of pages result in similar row patterns of the transition matrix. We demonstrate that common ro
