Infrared Small Target Detection via Non-Convex Tensor Rank Surrogate Joint Local Contrast Energy

Remote Sensing, 2020
Small target detection is a crucial technique that restricts the performance of many infrared imaging systems. In this paper, a novel detection model of infrared small target via non-convex tensor rank surrogate joint local contrast energy (NTRS) is ...

Dynamic Substructuring of Damped Structures Using Singular Value Decomposition [PDF]

Journal of Applied Mechanics, 1997
This paper deals with the theoretical aspects concerning linear elastodynamic of damped continuum medium in the frequency domain. Eigenvalue analysis and frequency response function are studied. The methods discussed here use a dynamic substructuring approach.

Matrix Nearness Problems, D-Stability and μ-Values in Economic Models

IEEE Access
In this paper, we investigate the interconnection between $D$ -stability and the structured singular value ( $\mu $ -values) to analyze linear time invariant dynamical systems subject to structured uncertainties.

Compression Reconstruction and Fault Diagnosis of Diesel Engine Vibration Signal Based on Optimizing Block Sparse Bayesian Learning

Sensors, 2022
It is critical to deploy wireless data transmission technologies remotely, in real-time, to monitor the health state of diesel engines dynamically. The usual approach to data compression is to collect data first, then compress it; however, we cannot ...

Computing Structured Singular Values for Sturm-Liouville Problems

International Journal of Analysis and Applications, 2019
En este artículo presentamos el cálculo numérico de pseudoespectros y los límites de valores singulares estructurados (SSV) para una familia de matrices obtenidas al considerar la representación matricial de problemas de SturmLiouville (S-L) con condiciones de límite dependientes de parámetros propios.

Interpreting Deep Graph Convolutional Networks with Spectrum Perspective

Mathematics, 2023
Graph convolutional network (GCN) architecture is the basis of many neural networks and has been widely used in processing graph-structured data. When dealing with large and sparse data, deeper GCN models are often required.

Block-encoding structured matrices for data input in quantum computing [PDF]

Quantum
The cost of data input can dominate the run-time of quantum algorithms. Here, we consider data input of arithmetically structured matrices via $\textit{block encoding}$ circuits, the input model for the quantum singular value transform and related ...

Comparing the Performance of Robust Controllers for Vibration Suppression in Long Rotor Systems

Acoustics
In this paper, the vibration control of the multivariable model of rotor bearing systems is considered for investigation. Some simply structured controllers that can suppress vibrational disturbances are tested for their robustness via the H∞ optimality ...
