Optimal design of linear phase FIR digital filters with very flat passbands and equiripple stopbands [PDF]
, 1985 A new technique is presented for the design of digital FIR filters, with a prescribed degree of flatness in the passband, and a prescribed (equiripple) attenuation in the stopband.

Roundoff error analysis of the CholeskyQR2 algorithm in an oblique inner product
JSIAM Letters, 2016 The Cholesky QR algorithm is an ideal QR decomposition algorithm for high performance computing, but known to be unstable. We present error analysis of the Cholesky QR algorithm in an oblique inner product defined by a positive definite matrix, and show ...

A new approach to the realization of low-sensitivity IIR digital filters [PDF]
, 1986 A new implementation of an IIR digital filter transfer function is presented that is structurally passive and, hence, has extremely low pass-band sensitivity. The structure is based on a simple parallel interconnection of two all-pass sections, with each

Initial and Boundary Conditions for the Lattice Boltzmann Method [PDF]
, 1993 A new approach of implementing initial and boundary conditions for the lattice Boltzmann method is presented. The new approach is based on an extended collision operator that uses the gradients of the fluid velocity.

Round-Off Error Suppression by Statistical Averaging
AxiomsRegarding round-off errors as random is often a necessary simplification to describe their behavior. Assuming, in addition, the symmetry of their distributions, we show that one can, in unstable (ill-conditioned) computer calculations, suppress their ...

A Model for Understanding Numerical Stability
, 2005 We present a model of roundoff error analysis that combines simplicity with predictive power. Though not considering all sources of roundoff within an algorithm, the model is related to a recursive roundoff error analysis and therefore capable of ...

Automated Roundoff Error Analysis of Probabilistic Floating-Point Computations
ACM Transactions on Probabilistic Machine LearningWe 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 ...

A parallel integration method for solar system dynamics [PDF]
, 1996 We describe how long-term solar system orbit integration could be implemented on a parallel computer. The interesting feature of our algorithm is that each processor is assigned not to a planet or a pair of planets but to a time-interval.
