Sensitivity of the inverse wave crest problem
نویسندگان
چکیده
Abstract. In a previous paper [1] the inverse problem for wave crests was introduced and a solution strategy for two-wave interactions was given. Here these solutions are actually constructed, in particular for the cases with small interaction angle, moderate phase shifts, and/or symmetric interactions. Two detailed examples are presented and analyzed. The sensitivity of the method is investigated, and conclusions about the practical applicability are given.

Application of different inverse methods for combination of vS and vGPR data to estimate porosity and water saturation
Inverse problem is one of the most important problems in geophysics as model parameters can be estimated from the measured data directly using inverse techniques. In this paper, applying different inverse methods on integration of S-wave and GPR velocities are investigated for estimation of porosity and water saturation. A combination of linear and nonlinear inverse problems are solved. Linear ...
متن کاملAnalysis of Natural Frequencies for a Laminated Composite Plate with Piezoelectric Patches using the First and Second Eigenvalue Derivatives
In this paper, the first and second order approximations of Taylor expansion are used for calculating the change of each natural frequency by modifying an arbitrary parameter of a system with a known amount and based on this approximation, the inverse eigenvalue problem is transformed to a solvable algebraic equation. The finite element formulation, based on the classical laminated plate theory...
متن کاملThree dimensional shear wave scattering MR elastography
Introduction: Magnetic resonance elastography (MRE) is a non invasive method that combines externally applied vibrations with the motion sensitivity of MRI to measure the shear elasticity soft tissues [1]. In MRE this is traditionally achieved by solving an inverse problem with MRE shear wave images as input data [2]. A complementary approach, which does not require the solution of an inverse p...
متن کاملPrediction of Mean Overtopping Discharge at Vertical Seawalls Using MLR and GLM Statistical Approaches
Wave overtopping at breakwaters is one of their essential hydraulic characteristics when determining the design crest level. This study concentrates on developing a new practical formula on predicting wave overtopping, by implementing two different statistical models, Multiple Linear Regression model (MLR) and Generalized Linear Regression model (GLM). The models consider dependency of overtopp...

A single spherical antenna is capable of measuring the direction and polarization of a gravitational wave. It is possible to solve the inverse problem using only linear algebra even in the presence of noise. The simplicity of this solution enables one to explore the error on the solution using standard techniques. In this paper we derive the error on the direction and polarization measurements ...
