The Influence of Nonlinear High-Intensity Dynamic Processes on the Standing Wave Precession of a Non-Ideal Hemispherical Resonator

open access: yesSensors
The properties of small size, low noise, high performance and no wear-out have made the hemispherical resonator gyroscope a good choice for high-value space missions. To enhance the precision of the hemispherical resonator gyroscope for use in tasks with

Comparison of the method of averages with the method of least squares. [PDF]

open access: yesMathematics of Computation, 1968
It is shown that the computationally simple method of averages can yield a surprisingly good solution of an overdetermined system of linear equations, provided that the grouping of the equations is done in an appropriate way. The notion of angle between linear subspaces is applied in a general comparison of this method and the method of least squares ...

Convergence of the Generalized Volume Averaging Method on a Convection-Diffusion Problem: A Spectral Perspective [PDF]

open access: yes, 2005
A mixed formulation is proposed and analyzed mathematically for coupled convection-diffusion in heterogeneous medias. Transfer in solid parts driven by pure diffusion is coupled with convection-diffusion transfer in fluid parts.

The averaging of nonlocal Hamiltonian structures in Whitham's method

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
We consider the m-phase Whitham's averaging method and propose the procedure of “averaging” nonlocal Hamiltonian structures. The procedure is based on the existence of a sufficient number of local-commuting integrals of the system and gives the Poisson ...
