En este artículo se muestra el proceso de solución numérica del ejercicio N°40, página 544, del libro "Cálculo de un variable'', con la finalidad de cumplir los requerimientos para el trabajo final de modelación de la asignatura Cálculo Integral. Por medio de la aplicación de integrales, se determinará la ecuación para el cálculo de la longitud de un cable telefónico y se hallará la altura a la cual debe estar conectado el cable teniendo en cuenta la altura mínima de este respecto al suelo, y la distancia de separación entre ambos postes.

This article investigates the bootstrap methods for producing good approximate confidence intervals. The first section introduces the motivated example and compare different approximated confidence intervals with the exact intervals. Section two serves as an overview of different bootstrap methods. Inspired by Efron's paper (1994), this article further explores the possibility to apply the bootstrap method to common odds ratio in a series of 2x2 contingency tables. The third section explains the procedure and gives the results of Monte Carlo simulations.

This study aimed to determine the effects of climate change on forest fire trends in Canada by measuring correlations between weather conditions and the frequency and size of forest fires. Upon identifying the correlations, a model was created to understand future forest fire trends. The purpose of this study was to prevent the increasing trend of forest fires and devise solutions to reduce their damages. The data obtained from the Canadian National Fire Database underwent a linear regression and a machine learning algorithm to respectively predict and correlate weather conditions with future forest fire trends. It was concluded that temperature and wind speed experienced a positive correlation with forest fire frequency and size and precipitation experienced a negative correlation. To reduce the harmful effects of forest fires, cloud seeding can be used to create more precipitation and wind farms can be built to lower wind speed and attract lightning. However, more research and stricter policies directly targeting climate change are necessary for long term stability or decrease in forest fire trends.

The use of technological resources in education has lead to positive changes in the elaboration of new methodologies, in this context technologies such as the Digital Interactive Whiteboard (DIW) can act by facilitating Learning. The mere presence of the DIW does not guarantee benefits for the student's learning process, that raises doubts about whether or not the resources available are used in a satisfactory manner. In this research it was possible to verify that there are few tools available for the DIW context, and many of them have problems of usability and content quality. Thus, a form of facilitate the content elaboration for the DIW is the use of Authoring Tools (ATs). In order to verify whether or not the use of ATs promotes better use of the DIW, an AT (entitled AtauDIW) was developed to assist the use of DIWs.

A System Design Language provides a means of communicating a design and an approach to determine the effectiveness of a design before it is built. This design language helps to guide the decomposition of the design by asking the right questions at the right time. The process of defining system requirements, communicating these requirements and their chosen solutions, and determining the effectiveness is explained within this primer.

se presenta el desarrollo de un algoritmo bajo código fuente JavaScript para la solución de la ecuación de flujo crítico (2). Se implementó un lenguaje de programación orientado a objetos para sistemas Android 4.0 o superiores a partir de procesos iterativos e incrementales (Desarrollo ágil). Se utilizó el método numérico de Newton-Raphson para determinar la profundidad crítica de sietes secciones hidráulicas (Rectangular, trapezoidal, trapezoidal asimétrico, triangular, triangular asimétrico, parabólico y circular). Con el propósito de acelerar y garantizar el nivel de convergencia para cada una de las secciones se obtuvo una función potencial para establecer el valor semilla en el proceso iterativo, este valor se asocia de manera directa a las condiciones preestablecidas del problema hidráulico. La aplicación calcula la profundidad crítica, velocidad crítica, área
