Multiquadrant digital analysis of shoulder capsular thickness

Arthroscopy: The Journal of Arthroscopic & Related Surgery, 2000
Nonablative thermal capsular shrinkage has been developed in an attempt to address the plastic capsule deformation thought to cause increased rates of recurrent instability following arthroscopic stabilization procedures. Although the temperature required to optimize collagen shrinkage is known, a safe depth of thermal penetration, in various locations

Multiquadric surfaces in C

Computers & Geosciences, 1994
Abstract Hardy's multiquadric method is used as a basis for fitting irregular, continuous surfaces where z = f ( x , y ). Four stages are involved in the implementation of the method: (1) solution of a system of simultaneous, linear equations; (2) interpolation of new z values, using a multiquadric equation, for any number of locations within ...

Convergence of Univariate Quasi-Interpolation Using Multiquadrics

IMA Journal of Numerical Analysis, 1988
Quasi-interpolants to a function f: \(R\to R\) on an infinite regular mesh of spacing h can be defined by \(s(x)=\sum^{\infty}_{j=- \infty}f(jh)\psi (x-jh),\) (x\(\in R)\), where \(\psi\) : \(R\to R\) is a function with fast decay for large argument. In the approach employing the radial-basis-function \(\phi\) : \(R\to R\), the function \(\phi\) is a ...

Multiquadric Solution for Shallow Water Equations

Journal of Hydraulic Engineering, 1999
A computational algorithm based on the multiquadric, which is a continuously differentiable radial basis function, is devised to solve the shallow water equations. The numerical solutions are evaluated at scattered collocation points and the spatial partial derivatives are formed directly from partial derivatives of the radial basis function, not by ...

Improved multiquadric approximation for partial differential equations

Engineering Analysis with Boundary Elements, 1996
Abstract Based on the idea of the DRM, a numerical method has been devised to interpolate the forcing term of partial differential equations by using multiquadric approximations, a special class of radial basis functions, and then use them to approximate particular solutions. To obtain a good shape parameter of the multiquadrics, we use the technique

Approximation of the objective function: multiquadrics versus neural networks

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 1999
Global optimization in electrical engineering using stochastic methods requires usually a large amount of CPU time to locate the optimum, if the objective function is calculated either with the finite element method (FEM) or the boundary element method (BEM).

Sampling and recovery using multiquadrics

2015 International Conference on Sampling Theory and Applications (SampTA), 2015
We survey recent results in the subject of interpolating bandlimited functions from their samples at both uniform and nonuniform sets via translates of a family of multiquadrics. Recovery of the original function is considered by means of a limiting process which changes a shape parameter associated with the multiquadric function.
