Some results on Drazin-Dagger matrices, reciprocal matrices, and conjugate EP matrices [PDF]

open access: yesJournal of Mahani Mathematical Research
In this paper, a class of matrices, namely, Drazin-dagger matrices, in which the Drazin inverse andthe Moore-Penrose inverse commute, is introduced. Also, some properties of the generalized inverses of these matrices, are investigated.

Programmable Reconfiguration of Hybrid 4D Chiral Metamaterials via Mechanical and Thermal Stimuli

open access: yesAdvanced Engineering Materials, EarlyView.
A class of hybrid chiral mechanical metamaterials is designed to achieve programmable reconfiguration through soft networks, hinges, and bilayer joints integrated with rigid units. Responsive to mechanical and thermal stimuli, these structures exhibit large volume changes, tunable deformation pathways, and both positive and negative thermal expansion ...

On some linear two-point inverse problem for a multidimensional heat conduction equation with semi-nonlocal boundary conditions

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
It is known that V.A. Ilyin and E.I. Moiseev studied generalized nonlocal boundary value problems for the Sturm-Liouville equation, the nonlocal boundary conditions specified at the interior points of the interval under consideration. For such problems,

Inverses and eigenvalues of diamondalternating sign matrices

open access: yesSpecial Matrices, 2014
An n × n diamond alternating sign matrix (ASM) is a (0, +1, −1)-matrix with ±1 entries alternatingand arranged in a diamond-shaped pattern. The explicit inverse (for n even) or generalized inverse (for nodd) of a diamond ASM is derived.

On generalized inverses of Boolean Matrices

open access: yesLinear Algebra and its Applications, 1975
AbstractAnalogous to minimum norm g-inverses and least squares g-inverses for real matrices, we introduce the concepts of minimum weight g-inverses and least distance g-inverses for Boolean matrices. All those Boolean matrices which admit such g-inverses are characterized.This paper is a continuation of [2].

Influence of Layering and Curie Temperature Uncertainty on the Performance of Multilayer Active Magnetic Regenerators

open access: yesAdvanced Functional Materials, EarlyView.
This study examines how manufacturing uncertainties in Curie temperatures (1.5–2°C) affect multilayer active magnetic regenerators (AMR). While increasing the number of magnetocaloric layers boosts cooling power, performance degrades due to temperature variations.

The new generalized inverse Weibull distribution

open access: yesپژوهش‌های ریاضی, 2015
Failure rate is one of the important concepts in reliability theory. In this paper, we introduce a new distribution function containing four parameters based on inverse Weibull distribution.
