Parts of the Whole: Error Estimation for Science Students

open access: yesNumeracy, 2017
It is important for science students to understand not only how to estimate error sizes in measurement data, but also to see how these errors contribute to errors in conclusions they may make about the data. Relatively small errors in measurement, errors

An Introduction to Affine Arithmetic

open access: yesTrends in Computational and Applied Mathematics, 2003
Affine arithmetic (AA) is a model for self-validated computation which, like standard interval arithmetic (IA), produces guaranteed enclosures for computed quantities, taking into account any uncertainties in the input data as well as all internal ...

An exact solution of truss vibration problems; pp. 244–263 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2019
The Elements by a System of Transfer equations (EST) method offers exact solutions to various vibration problems of trusses, beams, and frames. The method can be regarded as an improved or modified transfer matrix method.

On fully discrete collocation methods for solving weakly singular integral equations

open access: yesMathematical Modelling and Analysis, 2009
A popular class of methods for solving weakly singular integral equations is the class of piecewise polynomial collocation methods. In order to implement those methods one has to compute exactly certain integrals that determine the linear system to be ...

On the convergence of the gradient descent method with stochastic fixed-point rounding errors under the Polyak–Łojasiewicz inequality [PDF]

open access: yesComputational optimization and applications, 2023
In the training of neural networks with low-precision computation and fixed-point arithmetic, rounding errors often cause stagnation or are detrimental to the convergence of the optimizers.

A Note on the Construction of Explicit Symplectic Integrators for Schwarzschild Spacetimes

open access: yesThe Astrophysical Journal, 2022
In recent publications, the construction of explicit symplectic integrators for Schwarzschild- and Kerr-type spacetimes is based on splitting and composition methods for numerical integrations of Hamiltonians or time-transformed Hamiltonians associated ...

Rigorous Roundoff Error Analysis of Probabilistic Floating-Point Computations [PDF]

open access: yesInternational Conference on Computer Aided Verification, 2021
We present a detailed study of roundoff errors in probabilistic floating-point computations. We derive closed-form expressions for the distribution of roundoff errors associated with a random variable, and we prove that roundoff errors are generally ...

An Efficient Algorithm for the Reflexive Solution of the Quaternion Matrix Equation AXB+CXHD=F

open access: yesJournal of Applied Mathematics, 2013
We propose an iterative algorithm for solving the reflexive solution of the quaternion matrix equation AXB+CXHD=F. When the matrix equation is consistent over reflexive matrix X, a reflexive solution can be obtained within finite iteration steps in the ...
