El "unravelling" para bigráficas diferenciales
(2009-02-18)Here are examined the main properties of the algorithm called ¨unravelling¨ for differential bigraphs. This algorithm was originally developed for differential graded categories and was useful in the proof the celebrated ... -
El Análisis de la Variación Estacional en Medicina
(2012-03-08)This is a survey of recent methods for the analysis of seasonal variation in medical research. These methods are effective even when the data show small amplitude and the sample size is small, two characteristics that are ... -
El análisis multivariado de datos como herramienta en la exploración de modelos en la comprensión de variables psicológicas
(2012-04-26)Psychology, as a behavioral science in a preparadigmathic state, needs the support of theoretical models that validate the constructs that it uses for explaining the phenomena it studies. For sustaining the advances in the ... -
El espacio cociente y algunas propiedades geométricas de los espacios de Banach
(2009-02-18)We state some geometric properties of Banach spaces, such as uniformly convex spaces, uniformly non-square spaces, local uniformly convex spaces, strictly convex spaces, etc., and we analyze the problem of translating such ... -
El método Statis como alternativa para detectar "response shift" en estudios de calidad de vida relacionada con la salud
(2009-02-27)After evaluating problems in conceptualisation of Quality of Life outcomes andestablishing an operational definition of HRQoL, we focus the attention on the different dimensions of Response Shift and the theoretical Models ... -
El nuevo orden mundial y el Consejo de Seguridad de las Naciones Unidas
(2009-02-18)The quota power of UN Security Council members are analysed from a mathematical point of view, using Game Theory. Results are generalized and applied to the current situation. Some recommendations are stated about the ... -
El Número Equivalente como medida de la Información en Análisis de Datos
(2012-03-28)Se recuerda la definición del número equivalente, propuesto para medir el número de unidades independientes de información y lo adaptamos al contexto del análisis multivariado de datos. Proponemos algunas propiedades en ... -
El problema del conjunto independiente en la selección de horarios de cursos
(2009-02-20)Registration process at the Universidad Aut´onoma Metropolitana is such thatevery student is free to choose his/her own subjects and schedule. Success of thissystem, based in the percentage of students that obtain a place ... -
El problema del multicubrimiento: una aplicación para la selección de paradas en la red de transporte de la Ciudad de México
(2009-02-20)In this paper an heuristic algorithm is developed. Its implementation is developedas well, in order to solve a sampling problem in the urban transportation network in Mexico City. The problem consist of the selection of ... -
Elaboración de una metodología para la evaluación de la vulnerabilidad sísmica
(2009-02-25)This work presents a methodology to assess the seismic vulnerability of a set ofstructures over a specific region. Using a simplified inference method we estimate theconditions of the structures in order to recommend either ... -
Equilibrio walrasiano en economías de intercambio
(2009-02-18)We present the aggregated excess demand functions in an exchange economy. We study the properties and the equilibrium price vector of the aggregated excess demand functions. We prove that the walrasian equilibrium is a ... -
Estabilizacíon del modelo poblacional de may a través de controles direccionales
(2009-02-19)The May population model consider a satiate parameter over the predators andhas an unstable equilibrium state surrounded by a limit cycle. This work gives acontrol strategy driven to disturb the model in such way that the ... -
Estimaciones de pobreza para áreas pequeñas en Costa Rica: una aplicación de los estimadores de contracción de Jame-Setein
(2007)En este artículo se prueban dos posibles métodos para estimar la pobreza en áreas pequeñas, los cuales se utilizaron para corregir los estimadores directos de las encuestas periódicas, apoyándose en la estimación censal. ... -
Estimación bayesiana en la familia Pareto generalizada
(2009-02-25)The generalized Pareto family of distributions with scale parameter > 0 andk form, has been used for modeling surplus over a given threshold, even though theparametric estimation in this family has some problems. In this ... -
Estimación de parámetros de regresión no lineal mediante colonia de abejas artificiales
(2013-04-04)Este trabajo presenta los resultados de la técnica heurística de ABC (Artificial Bee Colony) utilizada para estimar los parámetros de modelos de regresión no lineal. El algoritmo fue probado sobre 27 bases de datos de la ... -
Estimación del error en cierta clase de métodos numéricos combinados de estrategia recorrectora
(2009-02-20)This paper shows an analysis of the order for the approximation and roundofferrors in combined numerical scheme with recorrector strategy of Adams–Moulton–Bashfort family. These methods are used for the numerical solution ... -
Estimación no paramétrica de la densidad y de la regresión - previsión no paramétrica
(2009-02-18)We begin with a short wiew of non parametric estimation of density and regression; then we give details and interpretation of a forecasting method, called non parametric forecasting . We show different aspects, technical ... -
Estimating Parameters of Gumbel Distribution using the Methods of Moments, probability weighted Moments and maximum likelihood
(2012-03-02)We derive here estimators for the parameters of the Gumbel distribution using three estimating methods, namely, the probability weighted moments, the moment and the maximum likelihood methods. Furthermore, we compare the ... -
Estimation of General Equilibium Model in Dynamic Economies using Markov Chain Monte Carlo Methods
(2012-03-08)This paper describes a general procedure to do Bayesian inference based on the likelihood evaluation of the stochastic general equilibrium models (MEGE) through Markov Chain Monte Carlo methods (MCMC). The proposed methodology ... -
