Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

The Influence of Field‐Assisted Sintering Technology (FAST) Temperature and Cooling Rate on the Microstructural Evolution in Gamma‐Titanium Aluminide Alloy GE4822

open access: yesAdvanced Engineering Materials, EarlyView.
Controlling the Field Assisted Sintering Technology (FAST) parameters, dwell temperature and cooling rate, significantly influences the microstructural evolution in titanium aluminide GE4822. Significant γ‐lamellar colonies develop only upon cooling through the α‐transus.

Closure Operations on Intuitionistic Linear Algebras

open access: yesAnnales Mathematicae Silesianae
In this paper, we introduce the notions of radical filters and extended filters of Intuitionistic Linear algebras (IL-algebras for short) and give some of their properties.

First Integrals and Invariants of Systems of Ordinary Differential Equations

open access: yesMathematics
We investigate the interplay between monomial first integrals, polynomial invariants of certain group action, and the Poincaré–Dulac normal forms for autonomous systems of ordinary differential equations with a diagonal matrix of the linear part.

On supersymmetric E 11 exceptional field theory

open access: yesJournal of High Energy Physics, 2019
We construct an infinite system of non-linear duality equations, including fermions, that are invariant under global E 11 and gauge invariant under generalised diffeomorphisms upon the imposition of a suitable section constraint.

Dual spaces and bilinear forms in supertropical linear algebra [PDF]

open access: yesLinear and Multilinear Algebra, 2012
Continuing [5], this paper investigates finer points of supertropical vector spaces, including dual bases and bilinear forms, with supertropical versions of standard classical results such as the Gram-Schmidt theorem and Cauchy-Schwarz inequality, and change of base.

Engineering of Crystallinity to Amplify Chiroptical Activity of TiO2 Nanohelices for Enhancing Dissymmetric Circularly Polarized Photocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
Enhancing crystallinity through thermal annealing leads to amplifying the chiroptical activity of TiO2 nanohelices (NHs) fabricated by glancing angle deposition, ascribed to the suppression of charge trapping. The enhanced chiroptical activity can be converted into pronounced dissymmetric photocatalytic kinetics of circularly polarized photocatalysis ...

Hecke relations in rational conformal field theory

open access: yesJournal of High Energy Physics, 2018
We define Hecke operators on vector-valued modular forms of the type that appear as characters of rational conformal field theories (RCFTs). These operators extend the previously studied Galois symmetry of the modular representation and fusion algebra of

On a micropolar theory of growing solids

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2020
The present paper is devoted to the problem of boundary conditions formulation in the growing micropolar solid mechanics. The static equations of the micropolar continuum in terms of relative tensors (pseudotensors) are derived due to virtual work ...
