An investigation of a two-stage nonlinear vibration isolation system
(2013-03-18)
This paper investigates the most desirable configuration of a two-stage nonlinear vibration isolation system, in which the isolators contain hardening geometric stiffness nonlinearity and linear viscous damping. The force ...
A positional FEM Formulation for geometrical non-linear analysis of shells
(LATIN AMER J SOLIDS STRUCTURES, 2008)
This work presents a fully non-linear finite element formulation for shell analysis comprising linear strain variation along the thickness of the shell and geometrically exact description for curved triangular elements. ...
Non-linear Functional Brain Co-activations in Short-Term Memory Distortion Tasks
(Frontiers Media, 2021-12)
Recent works shed light on the neural correlates of true and false recognition and the influence of time of day on cognitive performance. The current study aimed to investigate the modulation of the false memory formation ...
A Simple maxwell Based Model in Order to Represent the frequency-dependent viscosity measured by ultrasound
(2008-12-01)
A previous work showed that viscosity values measured high frequency by ultrasound agreed with the values at low frequency by the rotational viscometer when conditions are met, such as relatively low frequency viscosity. ...

Generalized expressions of second and third order for the evaluation of standard measurement uncertainty
(2011)
The Guide to the Expression of Uncertainty in Measurement (GUM) requires the use of a
first-order Taylor series expansion for propagating uncertainties. However, when the mea-surement function is strongly non-linear the ...
A Capacity-Based Condition for Existence of Solutions to Fractional Elliptic Equations with First-Order Terms and Measures
(Springer, 2020-09)
In this manuscript, we appeal to Potential Theory to provide a sufficient condition for existence of distributional solutions to fractional elliptic problems with non-linear first-order terms and measure data ω:{(−Δ)su=| ...
Asymptotic approach for the nonlinear equatorial long wave interactions
(2011-08-30)
In the present work we use an asymptotic approach to obtain the long wave equations. The shallow water equation is put as a function of an external parameter that is a measure of both the spatial scales anisotropy and the ...

Third-order nonlinearities and other properties of molybdenum lead-pyrophosphate glass
(Elsevier B.V., 2015-04-01)
Glasses in the binary system (100-x)Pb2P2O7-xMoO(3), with x = 10-80 mol%, were synthesized by conventional melt-quenching technique. Thermal analysis, linear optical absorption, refractive index measurements, Raman scattering ...
