Best local weighted approximation: an approach with abstract seminorms
(Michigan state university press, 2020-02)
In this paper, we extend results given by Z´o and Cuenya in 2007 about a general approach to problems of best vector-valued approximation on small regions from a finite dimensional subspace of polynomials of some degree. ...
Hierarchical fuzzy relational models: Linguistic interpretation and universal approximation
(Ieee-inst Electrical Electronics Engineers IncPiscatawayEUA, 2006)
Thermally stimulated depolarizations: Disclosing an approximate universality
(Iop Publishing Ltd, 1996-12-14)
This paper presents an approximate universality displayed by thermally stimulated depolarization currents ruled by stretched exponential relaxations when properly re-scaled. A visually perfect universality occurs especially ...
On the undamped free vibration of a mass interacting with a Hertzian contact stiffness
(2011-12-01)
Three methods are used to determine the natural frequency of undamped free vibration of a mass interacting with a Hertzian contact stiffness. The exact value is determined using the first integral of motion. The harmonic ...
Observation and properties of the X(3872) decaying to J/ψπ+π- in pp̄ collisions at √s = 1.96 TeV
(2004-10-15)
The discovery of a new particle, X(3872) by the Belle collaboration in the decay mode B±→ XK± (X→ J/ψπ+π - was discussed. It was found that the mass of the X(3872) was measured to be 3872.0 ± 0.6(stat) ± 0.5 (syst) MeV/C2. ...
Maximal inequalities for a best approximation operator in Orlicz spaces
(Adam Mickiewicz University in Poznań. Faculty of Mathematics and Computer Sciences, 2011-08)
In this paper we study a maximal operator Mf related with the best ϕ approximation by constants for a function f ∈ L ϕ 0 loc(ℝn), where we denote by ϕ 0 for the derivative function of the C1 convex function ϕ. We get a ...
Dark Energy Survey year 3 results: covariance modelling and its impact on parameter estimation and quality of fit
(2021-12-01)
We describe and test the fiducial covariance matrix model for the combined two-point function analysis of the Dark Energy Survey Year 3 (DES-Y3) data set. Using a variety of new ansatzes for covariance modelling and testing, ...
Best Lp-Approximant pair on small intervals
(Michigan State University Press, 2015-03)
In this paper we study the behavior of best Lp-approximations by algebraic polynomials pairs on union of intervals, when the measure of them tends to zero.
Universal X packable composite resins in restitution of the approximal contacts.
