On Extended Chebyshev Systems With Positive Accuracy
(Academic Press Inc Elsevier ScienceSan Diego, 2017)
Spherical functions : the spheres vs the projective spaces
(2014)
In this paper we establish a close relationship between the
spherical functions of the n-dimensional sphere Sn ≃ SO(n + 1)/SO(n)
and the spherical functions of the n-dimensional real projective space
P n(R) ≃ SO(n + ...
Cl-contact and Cl-right equivalences of real semi-quasihomogeneous Cl function germs
(2014-01-01)
In this paper we investigate the Cl versions of contact and right equivalences of real semi-quasihomogeneous Cl function germs, 1 ≤ l ≤ ∞. The Cl-right equivalence implies Cl-contact equivalence for any 1≤ l ≤ ∞ and in ...
C^l-contact and C^l-right equivalences of real semi-quasihomogeneous C^l-function germs
(2014)
In this paper we investigate the C ` versions of contact and right equivalences of real semi-quasihomogeneous C ` function germs, 1 ≤ ` ≤ ∞. The C ` -right equivalence implies C ` -contact equivalence for any 1 ≤ ` ≤ ∞ and ...
Comparative study between powers of sigmoid functions, MLP-backpropagation and polynomials in function approximation problems
(Spie - Int Soc Optical Engineering, 1999-01-01)
Function approximation is a very important task in environments where the computation has to be based on extracting information from data samples in real world processes. So, the development of new mathematical model is a ...
Functional Equivalence of Imagined vs. Real Performance of an Inhibitory Task: An EEG/ERP Study
(Frontiers in Behavioral NeuroscienceFrontiers in Behavioral Neuroscience, 2016)
From Powers to Exponential Function
(Modestum, 2019-05)
The construction of the exponential function of a real exponent from the definition of the powers of a real number, and its properties, requires the notion of successions, a decimal approximation of a rational number, ...
Composition and invertibility for a class of generalized functions in the Colombeau's theory
(Gordon Breach Sci Publ Ltd, 2014)
Functionalization of kaolinite for removal of phosphate from urban sewage
(2021-01-01)
The PO43− widespread in urban sewages promotes eutrophication of water sources, with harmful effects to natural life and endanger human health. The removal of PO43− from urban sewage requires treatment at tertiary level, ...
