A Geometric Splitting Theorem
(2019)
Let G = G1...Gl be a connected noncompact semisimple
Lie group with Lie algebra g = g_1+g_2+....+ g_l acting topologically
transitive on a manifold M. We obtain a geometric splitting
of the metric on M that consider ...
Clustering binary data by application of combinatorial optimization heuristics
(2019-08-09)
We study clustering methods for binary data, first defining aggregation criteria that measure the compactness of clusters. Five new and original methods are introduced, using neighborhoods and population behavior combinatorial ...
Coastal Environments
(WCRP Conference for Latin America and the Caribbean: Developing, linking, and applying climate knowledge (WRCP-LAC), 2014-09-08)
It is presented in this document the summary community-based position paper on "Coastal environments", on the outcomes of the World Climate Research Programme (WCRP) Conference for Latin America and the Caribbean, Developing, ...
Estimación de población contagiada por Covid-19 usando regresión Logística generalizada y heurísticas de optimización
(2020-04-02)
En este trabajos se presenta una propuesta para la estimación de la poblaciones usando ajuste de curvas del tipo logística.
Este tipo de curvas se utilizan para el estudio de crecimiento de poblaciones, en este casos ...
General Chemistry Without Orbitals
(2020)
We illustrate the solutions of Schroedinger's equation for the hydrogen atom in coordinates of all four systems, and differentiate the applicability of orbitals in these four systems. We present reasons that future textbooks ...
Variación de la frecuencia de los ciclones tropicales en el Atlántico y Pacífico Tropical del Este debido a variaciones decadales e interanuales de la Temperatura Superficial del Mar
Variability in the frequency of tropical cyclones in the Atlantic and East Tropical Pacific associated to decadal and interannual SST variability
(Memorias del “XI Congreso Latinoamericano e Ibérico de Meteorología y XIV Congreso Mexicano de Meteorología”, CD electronic document., 2005-03)
Para la cuenca del Atlántico se confirmaron los resultados previos en los cuales periodos anómalamente cálidos (fríos) en la misma tienden a estar asociados con periodos de mayor (menor) frecuencia de huracanes, mientras ...
Zilber's Dichotomy for Differentially Closed Fields with an Automorphism
(2020-07-01)
The theory of difference-differential fields of characteristic zero hasa model-companion denoted byDCFA. In [2] we prove its main properties. In[3] we proved a weak version of Zilber’s dichotomy forDCFA. In this paperwe ...
Using generalized logistics regression to forecast population infected by Covid-19
(2020-04-05)
In this work, a proposal to forecast the populations using generalized logistics regression curve fitting is presented.
This type of curve is used to study population growth, in this case population of people infected ...
Definable Additive Subgroups of Partial Differential Fields of Characteristic Zero with an Automorphism
(2020-10-19)
Abstract.The theory of partial differential fields of characteristic zero withan automorphism has a model companion denoted DCFmA. This theory isnot complete, but its completions are easily discribed. They are supersimpleand ...
La Corriente en Chorro del Caribe: Observaciones, modelado multifísica, interacciones multiescala e impacto regional
(2018-06)
El tema central de la propuesta es el estudio de la Corriente en Chorro del Caribe (CLLJ por sus siglas en inglés). El CLLJ es uno de los mecanismos físicos más importantes para entender el clima, la variabilidad climática ...
