The Relationship between Administrative Intensity and Student Retention and Success: A Three-Year Study

open access: yesEducation Sciences, 2018
Through the lens of complexity theory and by utilizing the methodological framework set forth in Gander’s 1999 article regarding internal and external organizational elements of administrative intensity, this secondary data analysis study linked ...

Normative theory of visual receptive fields

open access: yesHeliyon, 2021
This article gives an overview of a normative theory of visual receptive fields. We describe how idealized functional models of early spatial, spatio-chromatic and spatio-temporal receptive fields can be derived in a principled way, based on a set of ...

Internal sets and internal functions in Colombeau theory

open access: yesJournal of Mathematical Analysis and Applications, 2008
Inspired by nonstandard analysis, we define and study internal subsets and internal functions in algebras of Colombeau generalized functions. We prove a saturation principle for internal sets and provide applications to Colombeau algebras.

Spectral methods for internal waves: indistinguishable density profiles and double-humped solitary waves [PDF]

open access: yesNonlinear Processes in Geophysics, 2011
Internal solitary waves are widely observed in both the oceans and large lakes. They can be described by a variety of mathematical theories, covering the full spectrum from first order asymptotic theory (i.e.

Solution of High Dimension Multi-objective Optimization Problem Based on Entropy and Membership Function [PDF]

open access: yesJisuanji gongcheng, 2016
A new fitness assignment strategy is proposed for solving the high dmension multi-objective optimization problem,which is the Fuzzy Relevance Entropy Method(FREM).The FREM is built by integrating the fuzzy information entropy theory and the membership ...

Topos theory and consistent histories: The internal logic of the set of all consistent sets [PDF]

open access: yesInternational Journal of Theoretical Physics, 1997
A major problem in the consistent-histories approach to quantum theory is contending with the potentially large number of consistent sets of history propositions. One possibility is to find a scheme in which a unique set is selected in some way. However, in this paper we consider the alternative approach in which all consistent sets are kept, leading ...

Fundamental Problems of Internal Gravity Waves Dynamics in Ocean [PDF]

open access: yes, 2013
In paper fundamental problems of internal gravity waves dynamics are considered. The solution of this problem is expressed in terms of the Green’s function and the asymptotic representations of the solutions are considered.

Submartingalas finitas, teoremas de convergencia y métodos no standard

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2012
Se examinan dos teoremas clásicos de convergencia de submartingalas en tiempo discreto, los de convergencia casi segura y en L^1, usando los métodos del análisis no standard. Se realiza para ello un estudio previo sobre las submartingalas finitas.
