An Improved Magnetic Field Method to Locate the Grounding Conductor
The location of the grounding grid conductors is critical for performing corrosion diagnosis and maintenance work. An improved magnetic field differential method to locate the unknown grounding grid based on truncation errors and the round-off errors ...

Algorithm for Calculating Primary Spectral Density Estimates Using FFT and Analysis of its Accuracy
Introduction. Fast algorithms for solving problems of spectral and correlation analysis of random processes began to appear mainly after 1965, when the algorithm of fast Fourier transform (FFT) entered computational practice.

Statistical Analysis of Rounded Data: Measurement Errors vs Rounding Errors [PDF]
Consider the measurements in which the discretization step is constant and without loss of generality is equal to 1. The measured value \(X\) is rounded to the closest integer \(X^*\) according to the rule \(X^*=[X+0.5]\) where \([x]\) is the integer part of \(x\). Measurements of the quantity \(\mu\) are considered as i.i.d. random samples \(X_1,\dots,

Researchers often report a measure to several decimal places more than what is sensible or realistic. Rounding involves replacing a number with a value of lesser accuracy while minimizing the practical loss of validity.

ROUNDING ERRORS AND THEIR EFFECTS
The motivation to write this paper is the fact that students often blindly trust the results of a computation with the computer and rarely question the results. The general opinion is that the computer is perfect and errors only come into the game because of human errors such as faulty programs or incorrect operation.

Modeling Round-Off Errors in Hydrodynamic Simulations [PDF]
The growth of the computing capacities makes it possible to obtain more and more precise simulation results. These results are often calculated in binary64 with the idea that round-off errors are not significant. However, exascale is pushing back the known limits and the problems of accumulating round-off errors could come back and require increasing ...
