Infinite eigenvalue assignment by an output feedback for singular systems

open access: yes, 2004
The problem of an infinite eigenvalue assignment by an output feedback is considered. Necessary and sufficient conditions for the existence of a solution are established.

Linear and Two‐Dimensional Infrared Spectroscopy of the Multifunctional Vibrational Probe, 3‐(4‐Azidophenyl) Propiolonitrile. Deperturbing a Fermi Triad by Isotopic Substitution

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Linear infrared spectroscopy combined with isotope labeling and density functional theory unravels the origin of a Fermi triad in a multifunctional vibrational chromophore. Ultrafast 2DIR‐spectroscopy reports directly on the dynamics and the intramolecular vibrational energy flow pathways in the isotopically deperturbed system. Abstract Infrared probes

Pole assignment with minimum eigenvalue differential sensitivity

open access: yes, 1997
This paper introduces a set of mathematical formulae for calculating the eigenvalue differential sensitivities of the closed-loop state matrix with respect to the open-loop state matrix, input matrix and state feedback matrix. It provides a computational

Breaking Down Online and Digital Reporting Practices: A Research Map From Websites to Social Media

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This paper adopts a mixed research methodology, integrating bibliometric and systematic literature review (SLR) tools, to systematise the academic contributions and the different bodies of knowledge generated over the last decades on online and digital reporting practices, ranging from websites to social media.

An Efficient Quasi‐Static Condensation‐Based Framework for Seismic Analysis of Multi‐Supported Secondary Structures

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Multi‐supported non‐structural components (NSCs) are prone to seismic damage, yet their response prediction remains challenging when support motions are spatially incoherent. This study proposes an enhanced quasi‐static condensation (EQSC) method for linear, lightweight, dynamically detuned multi‐supported NSCs under the neglect of primary ...

Block-decomposition and multi-stage eigenvalue-assignment

open access: yes, 1984
A large-scale system often contains multi-modes of which the simulations and designs are extremely difficult. The large-scale system is usually block-decomposed into a system with either a block-trIangularized system map or a block-diagonalized system ...

Environmental Control for Edible Fungi Cultivation Based on Temporal Information and Deep Learning

open access: yesFood Bioengineering, EarlyView.
ABSTRACT Currently, there are still prevalent issues in greenhouse environmental regulation, such as response lag, low control accuracy, and difficulty in coping with sudden environmental disturbances. To achieve high‐precision and dynamic control of the edible fungi cultivation environment, this study proposes an edible fungi environmental control ...

Robust and minimum norm partial quadratic eigenvalue assignment problems : theory and computations

open access: yes, 2006
The partial eigenvalue assignment problem for a second-order control system, called the partial quadratic eigenvalue assignment problem (PQEVAP), is one of reassigning a few “troublesome” eigenvalues by using feedback while leaving the remaining large ...
