Eliminating Impulse for Descriptor System by Derivative Output Feedback

open access: yesJournal of Applied Mathematics, 2014
The problem of impulse elimination for descriptor system by derivative output feedback is investigated in this paper. Based on a novelly restricted system equivalence between matrix pencils, the range of dynamical order of the resultant closed loop ...

Matrix pencil generated by a tensor product from two matrix pencils

open access: yesLinear Algebra and its Applications, 1996
A pencil of matrices \(\lambda A-B\in\mathbb{C}[\lambda]^{m\times n}\) is regular if \(A\) and \(B\) are square matrices of the same order \(n\), and if the determinant \(|\lambda A-B|\) is not identically 0. Otherwise, the pencil is called singular.

Metal Battery Anode: Rich in Electrons, Rich in Problems: A Critical Review from Industrial Perspectives

open access: yesAdvanced Science, EarlyView.
Metal‐anode batteries using Li, Na, Mg, and Ca offer exceptionally high energy density, but dendrites, unstable interphases, cracking, and pore formation hinder durability and safety. This review shows how careful electrolyte and interphase design can stabilize these reactive metals.

The matrix pencil as a tunable filter

open access: yesJournal of Magnetic Resonance
Despite inherent sensitivity constraints, nuclear magnetic resonance (NMR) plays an indispensable role in probing molecular structures and dynamics across scientific disciplines. Remarkably, while extensive efforts have targeted instrumental and experimental sensitivity improvements, comparatively little focus has been dedicated to sensitivity ...

Design of Photocatalytic Composite Coatings for Formaldehyde Removal Based on the Visual Effects of Wood Furniture

open access: yesAdvanced Science, EarlyView.
This work develops photocatalytic coatings for indoor formaldehyde removal on wood surfaces. It explores coating‐induced color variations and visual perception via eye‐tracking tests. Combined with XGBoost and Bayesian optimization, an intelligent design framework is established to guide the optimization of visually friendly wood photocatalytic ...

On generalized inverses of singular matrix pencils [PDF]

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2011
On generalized inverses of singular matrix pencilsLinear time-invariant networks are modelled by linear differential-algebraic equations with constant coefficients. These equations can be represented by a matrix pencil. Many publications on this subject are restricted to regular matrix pencils.
