Estimation method of SBAS dual-frequency range error integrity parameter

open access: yesSatellite Navigation, 2020
The development of a dual-frequency multi-constellation satellite-based augmentation system (DFMC SBAS) is in progress worldwide. The broadcasted dual-frequency range error (DFRE) integrity parameter reflects the effects of satellite ephemeris and clock ...

On shrinking projection method for cutter type mappings with nonsummable errors

open access: yesJournal of Inequalities and Applications, 2023
We prove two key inequalities for metric and generalized projections in a certain Banach space. We then obtain some asymptotic behavior of a sequence generated by the shrinking projection method introduced by Takahashi et al. (J. Math. Anal. Appl.

Some Insights into the Method of Center Projection [PDF]

open access: yes, 1999
We present several new results which pertain to the successes of center projection in maximal center gauge (MCG). In particular, we show why any center vortex, inserted "by hand" into a thermalized lattice configuration, will be among the set of vortices

Approximation of maximal Cheeger sets by projection [PDF]

open access: yesESAIM: Mathematical Modelling and Numerical Analysis, 2008
This article deals with the numerical computation of the Cheeger constant and the approximation of the maximal Cheeger set of a given subset of \(\mathbb R^d\). This problem is motivated by landslide modeling as well as by the continuous maximal flow problem.

Convergence To Approximate Solutions of Multivalued Operators

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2023
The goal of this study is to provide a new explicit iterative process method  approach for solving maximal monotone(M.M )operators in Hilbert spaces utilizing a finite family of different types of  mappings as( nonexpansive mappings,resolvent mappings ...

Scaling and confinement aspects of tadpole improved SU(2) lattice gauge theory and its abelian projection [PDF]

open access: yes, 1997
Using a tadpole improved SU(2) gluodynamics action, the nonabelian potential and the abelian potential after the abelian projection are computed.

Selection, idioms, and the structure of nominal phrases with and without classifiers

open access: yesGlossa, 2018
It is common to hypothesize that in classifier and non-classifier languages alike the various functional heads (determiner/demonstrative, numeral, classifier) each head their own projection, so that the maximal projection of the nominal phrase is not NP ...

Abelian monopoles in lattice gluodynamics as physical objects [PDF]

open access: yes, 1997
By numerical calculations we show that the abelian monopole currents are locally correlated with the density of SU(2) lattice action. This fact is established for the maximal abelian projection.

The Gribov Ambiguity for Maximal Abelian and Center Gauges in SU(2) Lattice Gauge Theory [PDF]

open access: yes, 2000
We present results for the fundamental string tension in SU(2) lattice gauge theory after projection to maximal abelian and direct maximal center gauges. We generate 20 Gribov copies/configuration.
