Effect of sintering temperature on microstructure and nonlinear electrical characteristics of ZnO varistor [PDF]
Journal of Advanced Dielectrics, 2018 The nonlinear properties of ZBMCCS-based varistors, which are composed of ZnO–Bi2O3–MnO2–Cr2O3–Sb2O3–Co3O4 and SiO2 are studied inrelation to sintering temperature, in the range of 1280–1350∘C.

Nonlinear Helmholtz equations with sign-changing diffusion coefficient
Comptes Rendus. Mathématique, 2022 In this paper, we study nonlinear Helmholtz equations with sign-changing diffusion coefficients on bounded domains. The existence of an orthonormal basis of eigenfunctions is established making use of weak $\mathtt{T}$-coercivity theory.

Non-linearity of creep coefficient [PDF]
Geotechnical Research, 2020 This study investigated the non-linear void ratio–log(time) relationship during creep (secondary compression) under a range of loading history. Four long-duration creep tests on reconstituted clay soils from two different sites were performed. Data from tests reported in the literature (six long-duration creep tests on reconstituted marine deposits and

Research on Residual Life Estimation Method for KMN Steel Based on Nonlinear Ultrasonic Testing
Applied Sciences, 2021 The testing of KMN steel bending fatigue with different cycles was carried out using a nonlinear ultrasonic detector to obtain its nonlinear coefficient. The experimental results show that the nonlinear coefficient first increases and then decreases with

Enhanced conversion efficiency for harmonic generation with double resonance [PDF]
, 1993 Conversion efficiency for cw harmonic generation is calculated for the situation in which both fundamental and harmonic waves are resonant. Compared with the situation of a singly resonant cavity at the fundamental, the doubly resonant geometry can lead ...
