Observer-Based Exponential Stabilization for Time Delay Takagi–Sugeno–Lipschitz Models

Mathematics
This paper addresses the problem of observer-based control (OBC) for nonlinear systems with time delay (TD). A novel hybrid modeling framework for nonlinear TD systems is first introduced by synergistically combining TD Takagi–Sugeno (TDTS) fuzzy and ...

Nonlinear L-fuzzy stability of k-cubic functional equation

, 2015
In this paper, we establish the stability result for the k-cubic functional equation 2[k f(x + ky) + f(kx - y)] = k(k2 + 1)[f(x + y) + f(x - y)] + 2(k4 - 1)f(y), where k is a real number different from 0 and 1, in the setting of various L-fuzzy normed ...

Unlocking Terahertz Steganography: Authentication of Hidden Images in Flexible Media

Advanced Materials Technologies, EarlyView.
Hidden information in multilayered devices, such as steganographic portraits, is detected and authenticated using reflection‐mode terahertz time‐domain imaging. Image reconstruction relies on a dedicated figure‐of‐merit obtained by integrating the signal intensity over the time‐window associated with the reflection from the metallic mirror backing the ...

(L,M)-Fuzzy σ-Algebras [PDF]

, 2010
The notion of (L,M)-fuzzy σ-algebras is introduced in the lattice value fuzzy set theory. It is a generalization of Klement's fuzzy σ-algebras. In our definition of (L,M)-fuzzy σ-algebras, each L-fuzzy subset can be regarded as an L-measurable set to ...

Programming Actuation in 3D‐Printed Micro‐Architectures via Interfacial Adhesion Control

Advanced Materials Technologies, EarlyView.
A two‐phase meniscus‐guided 3D printing method directly fabricates microscale poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and poly(vinyl alcohol) (PVA) bilayers with in situ programmable interfaces. Modulating the meniscus stretching speed switches the interface between separated and bonded states, which controls the mechanical ...

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation

Advanced Optical Materials, EarlyView.
A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.

Hyperuniform Disorder in Photonic Crystal Slabs With Intrinsic Non‐Hermiticity

Advanced Optical Materials, EarlyView.
Light propagation in photonic crystal slabs with imposed hyperuniform disorder is investigated theoretically and numerically. The hyperuniform disorder is imposed by varying the hole size. The photonic crystal is intrinsically non‐Hermitian due to radiative loss, with non‐Hermiticity appearing as a complex effective mass of a quadratic photonic band ...

Parametrized Fuzzy Numbers for Option Pricing

, 2007
The growing interest, during the last years, in the managing of risk in financial markets has involved primarily the pricing models for derivatives. However some of these models seemed to be soon unsatisfactory due to the incapability to capture the ...

Remote Sensing Monitoring and Evaluation of Water Source Environmental Quality in Sanya

Urban Science
We addressed rising drinking water risks in tropical tourism catchments by selecting Sanya as a representative case and developing an integrated 10–16 m remote sensing framework (Sentinel-2, GF-1) with a fuzzy evaluation, combining NDVI, WET, and NDBSI ...
