On the number of τ(n)-factor
(2016)
In 2006, Anderson and Frazier defined the theory of τ-factorization as a generalization of the theory of comaximal factorizations given by McAdam and Swan. The theory of τ-factorization was built on integral domains. The ...
Aplicación de algoritmos meméticos en la programación de horarios de clases
(2012-08)
The objective of this research is to solve a scheduling problem using memetic algorithms which solve problems with a large number of variables and constraints. This method can be applied to different scheduling problems ...
Conjunto de productividad para problemas de análisis envolvente datos
(2004)
Data Envelopment Analysis (DEA) developed by A. Charnes, W Cooper and E. Rhodes, is a non-parametric method, based on linear programming. DEA is used to measure the productivity and the relative efficiency of units of ...
Matrices de covarianza estructuradas en modelos con medidas repetidas
(2005)
Many experiments in plants and animals, clinical trials and economic studies, have in common recording several measurements through time on the same experimental unit. These experiments use the mixed linear models with ...
Subespacios invariantes de algunos operadores
(2004)
In the following dissertation a number of results are received and presented. First the results obtained by Aronszajn-Smith and J Wermer concerning invariant subspaces of compact operators are received. Other bounded ...
Sieve bootstrap en series de tiempo de nubosidad en el caribe
(2006)
The Sieve Bootstrap is a resampling method, designed to deal with autocorrelated data, specifically a sequence of information taken at equal time intervals. Formally, the Sieve Bootstrap approximates a linear process by a ...
Flipped Classroom: An alternative teaching method for introductory statistics courses
(2017-05)
From a passive student to an active student. From a teacher-centered education to a student-centered education. The inverted class or flipped classroom is a new teaching method in which, in one of its versions, technology ...
Modelo computacional de un sistema para la extracción de la energía cinética de las olas
(2009-07)
The search for novel forms to generate electricity, renewable and clean, is a priority for today’s society. Renewable energy resources exploited and exploitable in each place are: the ability to produce biomass, position ...
Teoria de control para sistemas dinámicos monomiales sobre cuerpos finitos
(2010-12)
Monomical dynamical systems over finite fields have been studied in several contexts, including engineering and mathematical biology. Criteria for determining when a system described by monomials over finite fields, is a ...
Aplicación de las técnicas de componentes principales y componentes independientes como herramientas en los métodos de regresión lineal múltiple y clasificación no supervisada a partir de variables socio-económicas de Puerto Rico
(2015-06)
Studying the socio-economic aspect of Puerto Rico is of utmost importance for decision-making in the country. This thesis presents different findings, by applying the techniques of: Principal Components, Independent ...
