Modelling of radionuclide migration through the geosphere with radial basis function method and geostatistics [PDF]
, 2004 The modelling of radionuclide transport through the geosphere is necessary in the safety assessment of repositories for radioactive waste. A number of key geosphere processes need to be considered when predicting the movement of radionuclides through the

The parameter R2 in multiquadric interpolation
Computers & Mathematics with Applications, 1991 For bivariate interpolation to the data \((x_ i,y_ i,z_ i)\) where the \((x_ i,y_ i)\) are arbitrary points the multiquadric method has been frequently applied [for references, see: \textit{R. L. Hardy}, Comput. Math. Appl. 19, 163-208 (1990; Zbl 0692.65003)]. The accuracy of the method depends on a user defined parameter \(R^ 2\). In the present paper

Laminated Beam Analysis by Polynomial, rigonometric, Exponential and Zig-Zag Theories [PDF]
, 2013 A number of refined beam theories are discussed in this paper. These theories were obtained by expanding the unknown displacement variables over the beam section axes by adopting Taylor's polynomials, trigonometric series, exponential, hyperbolic and zig ...

Two-dimensional beams in rectangular coordinates using the radial point interpolation method
REM: International Engineering Journal, 2019 The three-dimensional Theory of Elasticity equations lead to a complex solution for most problems in engineering. Therefore, the solutions are typically developed for reduced systems, usually symmetrical or two-dimensional. In this context, computational

Computational issues by interpolating with inverse multiquadrics: a solution
CoRR, 2022 We consider the interpolation problem with the inverse multiquadric radial basis function. The problem usually produces a large dense linear system that has to be solved by iterative methods. The efficiency of such methods is strictly related to the computational cost of the multiplication between the coefficient matrix and the vectors computed by the ...

Multiquadric spline-based interactive segmentation of vascular networks [PDF]
2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016 Commonly used drawing tools for interactive image segmentation and labeling include active contours or boundaries, scribbles, rectangles and other shapes. Thin vessel shapes in images of vascular networks are difficult to segment using automatic or interactive methods.
