A Geometrical Study about the Biparametric Family of Anomalies in the Elliptic Two-Body Problem with Extensions to Other Families
(MDPI, 2024-02)
In the present paper, we efficiently solve the two-body problem for extreme cases such as those with high eccentricities. The use of numerical methods, with the usual variables, cannot maintain the perihelion passage ...
Modeling spatial dependencies of natural hazards in coastal regions: a nonstationary approach with barriers
(Springer, 2023)
Natural hazards like floods, cyclones, earthquakes, or, tsunamis have deep impacts on the environment and society causing damage to both life and property. These events can cause widespread destruction and can lead to ...
Bounded below composition operators on the space of Bloch functions on the unit ball of a Hilbert space
(Springer, 2023-09-04)
Let be the open unit ball of a complex finite or infinite dimensional Hilbert space E and consider the space of Bloch functions on . Using Lipschitz continuity of the dilation map on given by for , where denotes the ...
Dynamical and numerical analysis of classical multiple roots finding methods applied for different multiplicities
(Springer Nature, 2024-05-08)
The aim of this paper is the study of the robustness of classical methods defined for finding multiple roots with single multiplicity m when they are used for approximating different roots of a function having different ...
Lipschitz continuity of the dilation of Bloch functions on the unit ball of a Hilbert space and applications
(Springer, 2024-02-13)
Let BE be the open unit ball of a complex finite- or infinite-dimensional Hilbert space.
If f belongs to the space B(BE ) of Bloch functions on BE , we prove that the dilation
map given by x → (1 − x 2)R f (x) for x ∈ ...
The Lyrids meteor shower: A historical perspective
(Elsevier Science Direct, 2023-10-26)
The April Lyrid meteor shower is the oldest meteor shower ever recorded continuously throughout history, dating as far back as 687 BC. Before the 20th century, historical sources only provided reports of two years of strong ...
On the basins of attraction of a one-dimensional family of root finding algorithms: from Newton to Traub
(Springer, 2023)
In this paper we study the dynamics of damped Traub’s methods Tδ when applied to polynomials. The family of damped Traub’s methods consists of root finding algorithms which
contain both Newton’s (δ = 0) and Traub’s method ...
Endograph Metric and a Version of the Arzelà–Ascoli Theorem for Fuzzy Sets
(MDPI, 2023)
In this paper, we provide several Arzelà–Ascoli-type results on the space of all continuous functions from a Tychonoff space X into the fuzzy sets of Rn
, (FUSCB(Rn),Hend)
, which are upper semi-continuous and have bounded ...
Reliability Validation of a Low-Cost Particulate Matter IoT Sensor in Indoor and Outdoor Environments Using a Reference Sampler
(MDPI, 2019)
A suitable and quick determination of air quality allows the population to be alerted with respect to high concentrations of pollutants. Recent advances in computer science have led to the development of a high number of ...
Data on CO2, temperature and air humidity records in Spanish classrooms during the reopening of schools in the COVID-19 pandemic
(Elsevier, 2021-10-17)
In order to reduce the advance of the pandemic produced by COVID-19, many actions and restrictions have been applied and the field of education has been no exception. In Spain, during the academic year 2020–2021, face-to-face ...
