Item Galileo(Universidad de Cuenca, 2007-03) Universidad de Cuenca; Facultad de IngenieríaItem Calidad del agua y contaminantes en el río Tarqui(Universidad de Cuenca, 2013-06) Beltrán, Alberto; Mendieta, Paul; Vanegas, JuanThis research shows us specifically the contaminants in the Tarqui river located on the outskirts of Cuenca city. The parameters used to determine the water quality of the river were: DBO5 , fecal coliforms, water quality (Physical-Chemical), and the biotic index. The samples were taken at 8 different stations (1 station at the Portete River, 1 station at the Irquis River, 5 stations at the Tarqui River, and 1 station at the Cumbe River). What refers to DBO5 the samples are into the range of clean water; about the fecal coliforms were obtained bad results because of the intensive livestock in the area; the quality index that represents the condition throughout the river has label of good finally the biotic index indicates that the river´s healtn has a regular condition. These data reflects stability in the Tarqui River´s health except in the Cumbe River´s area where peaks of contamination appear.Item Sistema de tratamiento de aguas residuales de Ucubamba(Universidad de Cuenca, 2013-06) Ganzhi Fajardo, Fabián Patricio; Muñoz Gárate, Cristian; Rodríguez Pacheco, DanielThe wastewater treatment plant in Cuenca is located in the northeast of the city, in the area called Ucubamba. The main objectives aimed by the treatment plant can be summarized in the following ones: intercepting and conducting the water which formerly flowed to the rivers that run through the city and returning clean water to the environment. The ETAPA wastewater treatment plant is constituted by a preliminary treatment structure consisting of: settling tank, bypass, floodgates, mechanical screens, and grit chambers. After preliminary treatment of wastewater, the biological treatment stage starts, and it consists of three phases: aerated lagoons, facultative lagoons, and maturation lagoons. After the water is in suitable condition, it is moved by an unblock system which takes treated wastewater to the Cuenca River; this water can be safely reused in agriculture, hydropower, recreation, etc.Item Diseño y construcción de un dimmer inteligente para control a distancia de cuatro lámparas(Universidad de Cuenca, 2013-06) Fárez, Juan Pablo; Chumbi, RenéThis paper describes the development process to design and build a dimmer can con- trol four separate incandescent lamps by remote control, capable of maintaining the brightness of an environment automatically and store different brightness settings, in addition to rhythmic lights feature. It covers the conception and implementation of this equipment, without further detail in the description of the technical aspects.Item Arsénico en el agua(Universidad de Cuenca, 2013-06) Cabrera, María Alezandra; Pinos, David; Pulla, María FernandaArsenic (As) is a metalloid found naturally in air, soil and water. Have toxicological importance due to its environmental impact even in little concentrations. It is released by human activities and naturally by the earth’s crust. People can be exposed to arsenic mainly through food and water, especially in certain areas where groundwater comes into contact with arsenic containing minerals.Item Interacción gestual(Universidad de Cuenca, 2013-06) Parra González, Luis OttoItem El modelado conceptual en una arquitectura dirigida por modelos(Universidad de Cuenca, 2013-06) Granda Juca, María FernandaItem Calidad del agua en los ríos de Cuenca(Universidad de Cuenca, 2013-06) Alvarez, Diego Xavier; Cabrera, Tania; Loja, José LuisThis article describes how to measure water quality and its application to quantify water quality of rivers of Cuenca, studies of master plans, results and measures to achieve better water quality to get the current state.Item El cobro del peaje(Universidad de Cuenca, 2013-06) Peña Toral, Rómulo RolandoItem Control PID digital algoritmo, diseño e implementación(Universidad de Cuenca, 2013-06) Ochoa Correa, Danny VinicioItem Control PID aplicado sobre un variador de velocidad(Universidad de Cuenca, 2013-06) Fárez, Juan Pablo; Chumbi, RenéThis document is an automatic control project focused on the use of programmable logic controllers. The project is a speed control on a closed loop induction motor having as motor driver interface. The control system is dominated by logic programmed into the PLC the same turn interacts with the operator through an HMI. For purposes of study from the HMI commands the generation of different set point signal: sine wave, square wave with amplitude and frequency parameters configurable.Item El deslizamiento de la Josefina: "tragedia nacional"(Universidad de Cuenca, 2013-06) Zeas Domínguez, RodrigoItem Breve historia de la informática en la Universidad de Cuenca(Universidad de Cuenca, 2013-06) Guerrero Villavicencio, PatricioItem Estudio del concepto del parámetro de estabilidad de shields como un método para el diseño de canales erosionables(Universidad de Cuenca, 2013-06) Córdova Mora, Mario Andrés; Vallejo Llerena, Carolina ElizabethThis study discusses and analyzes the concept of the stability parameter in order to set the calculation expressions that allow the design of erodible channels. With the conceptual exposure of these processes, we have included an analysis of new mathematical relationships for the incipient motion curve and for determining the stability parameter. This paper is a contribution to the dissemination of knowledge and indicates a guide to the application of the method in the context of the course in Hydraulic. Design which is taught at the Career of Civil Engineering, Faculty of Engineering of the University of Cuenca.Item Informática urbana(Universidad de Cuenca, 2013-06) Espinoza Veintimilla, AngelItem Breves referentes de la historia universitaria(Universidad de Cuenca, 2013-06) Merchán, HernandoItem Medición de distancias a través de visión estereoscópica(Universidad de Cuenca, 2013-06) Romero Córdoba, FabiánA system that replaces the sense of sight is something that many engineers may need in industry for purposes of providing solutions to complex processes. As a particular case present a webcam based system for measurement of distances which can be useful to predict movements of objects in the production process.Item Desarrollo, ética y tecnología(Universidad de Cuenca, 2013-06) Pauta, GuillerminaItem Una primera aproximación a la implementación de un clúster para la ejecución de un modelo de predicción climática(Universidad de Cuenca, 2013-06) Gualán, Roland Marcelo; Vázquez, Angel Oswaldo; Vega, Oswaldo FranciscoItem Los cuatro pilares de la educación(Universidad de Cuenca, 2013-06) Delors, Jauqes
