Flexible Optoelectronic Hybrid Microfiber Long-period Grating Multimodal Sensor. [PDF]
Adv Sci (Weinh)An entirely new optoelectronic hybrid multimodal optical fiber sensor which can simultaneously monitor biomechanics and glucose is demonstrated. The developed method simultaneously integrates two heterogeneous sensing mechanisms, optical and electrical, into a single sensor in a compact manner. Optical and electrical sensors can work simultaneously but

Elastic transient analysis with MLPG(LBIE) method and local RBFs
Computer Modeling in Engineering & Sciences, 2009 A Meshless Local Petrov-Galerkin (MLPG) method based on Local Boundary Integral Equation (LBIE) techniques is employed here for the solution of transient elastic problems with damping. The Radial Basis Functions (RBF) interpolation scheme is exploited for the meshless representation of displacements throughout the computational domain.

Analysis of an MLPG Solution for 3D Potential Problems
, 2008 Meshless methods have been explored in many 2D problems and they have been shown to be as accurate as Finite ElementMethods (FEM). Compared to the vast literature on 2D applications, papers on solving 3D problems by meshless methods are surprisingly few. Indeed, a main drawback of these methods is the requirement for accurate cubature rules. This paper

A new Singular/Hypersingular MLPG (LBIE) method for 2D elastostatics
Computer Modeling in Engineering & Sciences, 2005 A new meshless local Petrov-Galerkin (MLPG) type method based on local boundary integral equation (LBIE) considerations is proposed for the solution of elastostatic problems. It is called singular/hypersingular MLPG (LBIE) method since the representation of the displacement field at the internal points of the considered structure is accomplished with ...

Numerical Methods for Partial Differential Equations, Volume 39, Issue 4, Page 2998-3019, July 2023., 2023 Abstract A novel Hermite radial basis function‐based differential quadrature (H‐RBF‐DQ) method is presented in this paper based on 2D variable order time fractional advection–diffusion equations with Neumann boundary conditions. The proposed method is designed to treat accurately for derivative boundary conditions, which considerably improve the ...

International Journal for Numerical Methods in Fluids, Volume 95, Issue 1, Page 143-175, January 2023., 2023 We present a new strong‐form meshless solver combined with the boundary condition‐enforced immersed boundary method for the numerical solution of the nonstationary, incompressible, viscous Navier–Stokes equations in their stream function‐vorticity (in 2D) and vector potential‐vorticity (in 3D) formulation.

Adaptive Numerical Method for Approximation of Traffic Flow Equations
Journal of Advanced Transportation, Volume 2022, Issue 1, 2022., 2022 For a long time now, traffic equations have been considered, and different modeling has been done for it. In this article, we work on the macroscopic model, especially the most famous light model. Because these models are among the stiff and shocking problems, theoretical methods do not give good answers to these problems.

Fracture and Fatigue Analyses of Cracked Structures Using the Iterative Method
Geofluids, Volume 2021, Issue 1, 2021., 2021 It is a quite challenging subject to efficiently perform fracture and fatigue analyses for complex structures with cracks in engineering. To precisely and efficiently study crack problems in practical engineering, an iterative method is developed in this study.

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021 In this article, a new sinusoidal shear deformation theory was developed for static bending analysis of functionally graded plates resting on elastic foundations. The proposed theory used an undefined integral term to reduce the number of the unknown to four without any shear correction factors.
