3D Measurement of Discontinuous Objects with Optimized Dual-frequency Grating Profilometry

open access: yesMeasurement Science Review, 2021
Three-dimensional profilometry tends to be less effective at measuring discontinuous surfaces. To overcome this problem, an optimized profilometry based on fringe projection is proposed in this paper.

On Relations between Some Types of (α,β)-Intuitionistic Fuzzy Ideals of Ternary Semigroups

open access: yesJTAM (Jurnal Teori dan Aplikasi Matematika), 2021
In this article, the notion of (α,β)-intuitionistic fuzzy ideals (briefly, (α,β)-IF ideals) of ternary semigroups is described using ”belong to” relation (ϵ) and “quasi-coincidence with” relation (q) connecting two objects, i.e., an intuitionistic fuzzy ...

Multiple solutions for Kirchhoff type problem near resonance

open access: yesElectronic Journal of Differential Equations, 2015
Based on Ekeland's variational principle and the mountain pass theorem, we show the existence of three solutions to the Kirchhoff type problem $$\displaylines{ -\Big(a+b\int_{\Omega}|\nabla u|^2dx \Big) \Delta u =b \mu u^3+f(x,u)+h(x), \quad\text{in

Numerical analysis of the wave propagation in a composite medium

open access: yesMathematical Modelling and Analysis, 2006
We consider the wave propagation process in a 2‐dimensional material structure composed of random oriented orthotropic crystals and analyse numerical results for the diffraction problem and the problem of waves interaction with a free boundary.

Properties of solutions in semi-hyperbolic patches for unsteady transonic small disturbance equations

open access: yesElectronic Journal of Differential Equations, 2015
We consider a two-dimensional Riemann problem for the unsteady transonic small disturbance equation resulting in diverging rarefaction waves. We write the problem in self-similar coordinates and we obtain a mixed type (hyperbolic-elliptic) system ...
