In this paper the possibility of reducing the round-off error in ERKN64 integrator is examined by using compensated summation technique [10].
In other words, the use of a recursion that produces a monotonically descending sequence in norm, leads to a rapid accumulation of round-off errors.
There are two main issues related to fixed point implementation of a digital filter: quantisation of filter coefficients and control of round-off errors.
The error of the simulation was the result of a number of causes including the assumptions employed in developing the numerical model, the discretization and round-off errors of numerical method, the using of general properties of the materials in the simulation, and the error in the estimation of the relative loss factor of epoxy adhesive.
Note that, for k = 4 (Table X), round-off error started to dominate the error observed in the mesh data values when more than 16 mesh points were used.
996 but it is not close enough to 1 as to trigger the amplification of the round-off errors found for x = Z and x = [?
Other topics include modeling semiconductor optical amplifier dynamics for telecommunication applications, the effect of round-off errors on molecular dynamics simulations, dielectric confinement in quantum dots, and bi-dimensional quantum tunneling by a time-dependent computational approach.
While simulating the equations' dynamics on a computer, Lorenz found that tiny round-off errors result in hugely different outcomes, a discovery that launched the field of chaos theory.
Run-length and LZW encoding result in no loss of data; DCT does in fact result in some data loss due to round-off errors, but the overall effect on the quality of the resulting image is inconsequential.
