We show that the nonlinear phase shift produced by a ring resonator constructed from a given nonlinear optical material can be greater than the phase shift produced by a single pass through an infinite length of the same material when linear and nonlinear absorption are taken into consideration. The figure of merit (defined by the phase shift times the throughput) also improves for the ring res...

In order to better understand the mechanical properties of biological cells, characterization and investigation of their material behavior is necessary. In this paper hyperelastic Neo-Hookean material is used to characterize the mechanical properties of mouse oocyte cell. It has been assumed that the cell behaves as continuous, isotropic, nonlinear and homogenous material for modeling. Then, by...

the collapse of a compression member gives rise to decrease of the load carrying capacity of the member. to perform a nonlinear analysis, in addition to the precritical behavior, the post-critical behavior of the compression member also must be determined. in this study, because of certain advantages of the finite element method, this method has been selected to evaluate the axial load-axial di...

In this paper, the thermal buckling analysis of a circular plate made of FGM materials with actuator/actuator piezoelectric layers based on neutral plane, classical plate theory and first order shear deformation plate theory is investigated. Reddy's model is assumed for material properties of FGM plate. Plate under the thermal loading, nonlinear temperature rise through the thickness and clampe...

Silos are structures that are used for storing different types of granular material. Dynamic behavior of silos under seismic loads is very complex. In this paper seismic behavior of steel silos with different height to diameter ratios is investigated by considering granular material-structure interaction using ABAQUS finite element package. Silo wall is modeled by shell elements and its behavio...

The mechanical properties of Nitinol stents are normally evaluated experimentally due to complexities resulting from large deformations and material nonlinearity. Despite the difficulties associated with Finite Element Analysis (FEA), the success of the computational analysis in combination with experimental study leads to better understanding of stent performance. This paper presents compariso...

Aim: The nonlinear elimination rate of THC and metabolites in blood complicates the interpretation of last cannabis use, which is an important information in DUID cases. We evaluated cannabinoids in blood and hydrolysed urine from 50 DUID cases in order to gain additional information about last cannabis use. Methods: THC, THC-OH and THC-COOH were analysed in blood and hydrolysed urine (βglucuro...

We consider the numerical solution of a nonlinear problem arising in in nondestructive detection of a corrosion at a hidden surface of a conductor. The problem can be naturally linearized and reduced to an elliptic Cauchy problem. In this paper we describe and test a regularized reconstruction algorithm based on a regularization by discretization, where the discretization level is chosen in dat...

We consider the inverse problem to recover a part Γc of the boundary of a simply connected planar domain D from a pair of Cauchy data of a harmonic function u in D on the remaining part ∂D \ Γc when u satisfies a homogeneous impedance boundary condition on Γc. Our approach extends a method that has been suggested by Kress and Rundell [17] for recovering the interior boundary curve of a doubly c...
