Classification of artificially aged lentil seeds using Fourier transform near-infrared spectroscopy

Pesquisa Agropecuária Tropical
Seed deterioration is among the main causes of loss in physiological potential. This study aimed to investigate the potential of Fourier transform near-infrared (FT-NIR) spectroscopy to classify lentil seeds subjected to artificial aging at 41 ºC and 100

Moment Stability of the Critical Case of PWM Feedback Systems with Stochastic Perturbations

Abstract and Applied Analysis, 2012
This paper further studies the moment stability of pulse-width-modulated (PWM) feedback system which is subjected to multiplicative and additive random disturbance modeled by the derivative of Wiener process. Different from the existing investigation, we

Logarithmic strain measure in finite element modelling of anisotropic hyperelastic materials

Computer Assisted Methods in Engineering and Science, 2023
A new finite element to analyze problems of anisotropic hyperelasticity is presented. The constitutive equations are derived by means of the energy method, which leads to the stress measure conjugate to the logarithmic strain.

Response analysis of the vibro-impact system under fractional-order joint random excitation

Journal of Low Frequency Noise, Vibration and Active Control
As a kind of good damping material, viscoelastic material is widely used in machinery, civil engineering, and other fields. In this paper, the viscoelasticity of the system is described by fractional differentiation.
