Analyzing the Measurement Equivalence of a Translated Test in a Statewide Assessment Program
Análisis de la equivalencia de la medida de la traducción de un test en un programa de evaluación estatal
(2016-09)
When tests are translated into one or more languages, the question of the equivalence of
items across language forms arises. This equivalence can be assessed at the scale level by means of
a multiple group confirmatory ...
Ley de grandes números en medio ambiente aleatorio
(2020)
Las condiciones (T)γ,γ ∈ (0,1) introducidas por Sznitman en 2002 tienen un significante impacto en el estudio de caminatas aleatorias sobre medios aleatorios (RWRE) . Este tipo de caminatas modelan, por ejemplo, el movimiento ...
Characterization of principal bundles: the commutative case
(2023-10-04)
A review of the characterization of principal bundles, through the different properties of the action of a group and its related canonical and translation maps, is presented. The work is divided in three stages: a topological ...
The Gromov’s centralizer theorem for semisimple Lie group actions
(2017-10)
We give a new version of the Gromov’s centralizer theorem in the case
of semisimple Lie group actions and arbitrary rigid geometric structures of algebraic
type.
Stark units and special Gamma values
(2021)
In this paper we develop an effective procedure for expressing Stark units in real quadratic extensions of totally real fields as values of the Barnes multiple Gamma function at algebraic points. This procedure is used to ...
On the Ramanujan–Lodge harmonic number expansion
(2015-01-15)
The aim of this paper is to extend and refine the Ramanujan–Lodge harmonic number expansion into negative powers of a triangular number. We construct a faster asymptotic series and some new sharp inequalities for the ...
Teorías y propiedades universales de una teoría de anillos real cerrados (Informe Final Proyecto B9128)
(2021)
Sea $T^\ast$ la teor\'{\i}a de los subanillos reticulados que son convexos en los $f$-anillos von Neumann regulares real cerrados, y que adem\'as no tienen elementos idempotentes minimales (no-cero) y que son divisible-p ...
Adicción a Redes Sociales: Un Modelo Matemático
(2023)
El artículo presenta un modelo de dinámica social para el estudio de la adicción a las redes sociales, basado en los modelos matemáticos SIR (Susceptibles-Infectados-Recuperados). El modelo considera cinco categorías de ...
Stochastic Integration With Respect to Cylindrical Semimartingales
(2021)
In this work we introduce a theory of stochastic integration with respect to general cylindrical semimartingales defined on a locally convex space Φ. Our construction of the stochastic integral is based on the theory of ...
