Evidence and Credibility: Full Bayesian Significance Test for Precise Hypotheses

open access: yesEntropy, 1999
: A Bayesian measure of evidence for precise hypotheses is presented. The intention is to give a Bayesian alternative to significance tests or, equivalently, to p-values. In fact, a set is defined in the parameter space and the posterior probability, its

Evaluation of Static Potential Integrals on Triangular Domains

open access: yesIEEE Access, 2020
Static potential integrals for constant and linear sources on triangles are derived in a straightforward way. The new representations, as presented, are robust with respect to machine evaluation in important limiting cases.

Estimation with Numerical Integration on Sparse Grids [PDF]

open access: yes, 2006
For the estimation of many econometric models, integrals without analytical solutions have to be evaluated. Examples include limited dependent variables and nonlinear panel data models.

Integrating rotation from angular velocity [PDF]

open access: yes, 2011
\ud The integration of the rotation from a given angular velocity is often required in practice. The present paper explores how the choice of the parametrization of rotation, when employed in conjuction with different numerical time-integration schemes ...

Tracking fluctuating targets in extremely heterogeneous clutter using amplitude information

open access: yesThe Journal of Engineering, 2019
This study analyses the radar fluctuating target detection in G(0)-distributed clutter using dynamic programming – track before detect (DP-TBD) algorithm. G(0)-distributed clutter is often used to fit the complex circumstances. The authors use chi-square

Numerical integration of variational equations

open access: yes, 2010
We present and compare different numerical schemes for the integration of the variational equations of autonomous Hamiltonian systems whose kinetic energy is quadratic in the generalized momenta and whose potential is a function of the generalized ...

Feedback Integrators for Mechanical Systems with Holonomic Constraints

open access: yesSensors, 2022
The feedback integrators method is improved, via the celebrated Dirac formula, to integrate the equations of motion for mechanical systems with holonomic constraints so as to produce numerical trajectories that remain in the constraint set and preserve ...

Taylor Polynomials in a High Arithmetic Precision as Universal Approximators

open access: yesComputation
Function approximation is a fundamental process in a variety of problems in computational mechanics, structural engineering, as well as other domains that require the precise approximation of a phenomenon with an analytic function. This work demonstrates
