The α-scalar diagonal stability of block matrices
Linear Algebra and its Applications, 2006 The paper deals with diagonal stability of block matrices. The author generalizes two results: the characterization of diagonal stability via Hadamard products [cf. \textit{J. F. B. M. Kraaijevanger}, ibid. 151, 245--254 (1991; Zbl 0724.15014)] and the block matrix version of the closure of the positive definite matrices under Hadamard multiplication ...

Diagonal Loading Beamforming Based on Aquila Optimizer
IEEE Access, 2023 Traditional beamforming algorithms are only applicable to ideal environments. When the array antenna receives data under circumstances of small snapshots or large signal-to-noise ratio(SNR), noise eigenvalues of classic sample matrix inversion(SMI) and ...

Study on Sloshing Characteristics in a Liquid Cargo Tank under Combination Excitation
Journal of Marine Science and Engineering, 2022 Sloshing is a common flow phenomenon in liquid cargo tanks and has a great negative impact on the stability and safety of ship navigation. It is important to understand the sloshing process of tanks under the excitation of complex external conditions for

Common diagonal solutions to the Lyapunov inequalities for interval systems
Journal of Inequalities and Applications, 2016 In this paper for interval systems we consider the problem of existence and evaluation of common diagonal solutions to the Lyapunov inequalities. For second order systems, we give necessary and sufficient conditions and exact solutions, that is, complete

Fuzzy Adaptive Control of Uncertain MIMO Chaotic Systems with Unknown Control Direction
Complexity, 2021 This paper presents an adaptive controller for MIMO chaotic systems with system uncertainties and unknown control direction. In the controller design, the matrix decomposition theory is used, and we decompose the control gain matrix into a positive ...

Dual-Task Gait Stability after Concussion and Subsequent Injury: An Exploratory Investigation
Sensors, 2020 Persistent gait alterations can occur after concussion and may underlie future musculoskeletal injury risk. We compared dual-task gait stability measures among adolescents who did/did not sustain a subsequent injury post-concussion, and uninjured ...
