Riesz bases of exponentials and the Bohr topology
(American Mathematical Society, 2021-02-23)
We provide a necessary and sufficient condition to ensure that a multi-tile Ω ⊂ Rd of positive measure (but not necessarily bounded) admits a structured Riesz basis of exponentials for L2(Ω). New examples are given and ...
Exponential convergence of multiquadric collocation method: A numerical study
(Universidad Nacional Autónoma de México, 2009)
Basis set convergence in Hartree-Fock calculations of some diatomic molecules containing first and second-row atoms
(2007)
Investiga-se a convergência de conjuntos de bases em direção ao limite numérico da energia Hartree-Fock (HF) total para as seqüências hierárquicas dos conjuntos de bases XZP e ccpVXZ. Para as duas hierarquias, melhoramentos ...
Correlated expansions of n 1 S and n 3 S states for two-electron atoms in exponential cosine screened potentials
(American Physical Society, 2014-01)
Two–electron atoms embedded in a plasma environment are studied with screened and exponential cosine screened Coulomb model potentials. Within a configuration interaction approach, and using parameter–free explicitly ...
A comparison of exponential smoothing and neural networks in time series prediction
(Universidad Nacional de Colombia Sede Medellín, 2013)
In this article, we compare the accuracy of the forecasts for the exponential smoothing (ES) approach and the radial basis function neural networks (RBFNN) when three nonlinear time series with trend and seasonal cycle are ...
Effects of exponentially decaying spatial patterns on the probability distribution of anomalous values
(Journal of Geochemical Exploration, 1983)
The nature of geochemical anomalies is discussed on a speculative basis. Anomalies
are classified as independent or as additive, depending on their spatial relation to the
background population. The additive anomalies, ...
El diseño frente al Internet de las cosas (IdC) y otros fenómenos
(Universidad Iberoamericana Ciudad de México, Departamento de Diseño, 2019)
Según Rifkin (2015) el Internet de las Cosas, el Procomún Colaborativo y el eclipse del capitalismo modifican ya el contexto social y prevén un futuro incierto para muchas profesiones, una de ellas, el diseño. Según Ismail ...
Hipercomplexos: um estudo da analicidade e da hiperperiodicidade de funções octoniônicas
(Universidade Estadual Paulista (Unesp), 2007-03-02)
Com o intuido de bem fundamentar bases teóricas para futuras aplicações dos octônios à Mecânica Quântica, Computação Quântica e Criptografia, um dos objetivos maiores deste trabalho é o de determinar e estudar a analiticidade ...
