Eigenvalue Problems for Fredholm Operators with Set-Valued Perturbations

Advanced Nonlinear Studies, 2020
By means of a suitable degree theory, we prove persistence of eigenvalues and eigenvectors for set-valued perturbations of a Fredholm linear operator.

A compatibility criterion for optimal control and information aggregation in hierarchical network systems

Asian Journal of Control, EarlyView.
Abstract Large swarms often adopt a hierarchical network structure that incorporates information aggregation. Although this approach offers significant advantages in terms of communication efficiency and computational complexity, it can also lead to degradation due to information constraints.

Evaluation of multi‐user multiple‐input multiple‐output digital beamforming algorithms in B5G/6G low Earth orbit satellite systems

International Journal of Satellite Communications and Networking, EarlyView., 2023
In this paper, we investigate the application of signal‐to‐leakage‐plus‐noise ratio (SLNR) beamforming to low Earth orbit non‐terrestrial networks. The SLNR criterion aims at maximizing the received desired signal power for each user while minimizing the overall interference power caused by each user to all other co‐channel receivers. We show that such

Sustainable Finance Disclosure Versus Performance: A Clustering Approach

Business Strategy and the Environment, EarlyView.
ABSTRACT The Sustainable Finance Disclosure Regulation (SFDR) imposes on investment companies the publication of sustainability related profiles of the portfolio creation process. This obligation seeks to enhance the information provided to customers on financial products with regard to the Environmental, Social and Governance (ESG) criteria.

A probabilistic diagnostic for Laplace approximations: Introduction and experimentation

Canadian Journal of Statistics, EarlyView.
Abstract Many models require integrals of high‐dimensional functions: for instance, to obtain marginal likelihoods. Such integrals may be intractable, or too expensive to compute numerically. Instead, we can use the Laplace approximation (LA). The LA is exact if the function is proportional to a normal density; its effectiveness therefore depends on ...

Complex modal analysis of structural vibration and acoustic radiation of plates

Journal of Low Frequency Noise, Vibration and Active Control
Inhomogeneous damping distribution leads to the occurrence of complex modes of structures. Complex modes' vibration and acoustic radiation characteristics are different from real modes.

Instantaneous Normal Modes of Yukawa Liquids

Contributions to Plasma Physics, EarlyView.
ABSTRACT The instantaneous normal mode (INM) approach, which extends the normal mode description of collective excitations in solids to liquids, is applied to strongly coupled, three‐dimensional Yukawa liquids. Based on data from Langevin dynamics simulations, we compute the instantaneous normal modes across a wide range of coupling and screening ...

Partial eigenvalue assignment problem of linear control systems using orthogonality relations [PDF]

Acta Montanistica Slovaca, 2006
The partial eigenvalue assignment is the problem of reassigning a part of the open-loop spectrum of a linear system by a feedback control, leaving the rest of the spectrum invariant.

Extremal Eigenvalues and Eigenvectors of Deformed Wigner Matrices [PDF]

, 2014
We consider random matrices of the form $H = W + \lambda V$, $\lambda\in\mathbb{R}^+$, where $W$ is a real symmetric or complex Hermitian Wigner matrix of size $N$ and $V$ is a real bounded diagonal random matrix of size $N$ with i.i.d.\ entries that are

From One Strand Dyed/Undyed Hair With/Without Root to Fast and Successful STR Profiling and Evaluation With Principle Component Analysis

ELECTROPHORESIS, EarlyView.
ABSTRACT Fallen/shed single hair shafts with/without roots can be encountered as evidence in crime scenes. Identification from hair exhibits serious difficulties, due to the low amount of DNA, PCR inhibitors, and the existence of DNA mostly in degraded forms. Exposure of hair to chemical oxidation, sunlight, etc.
