Item El modelado conceptual en una arquitectura dirigida por modelos(Universidad de Cuenca, 2013-06) Granda Juca, María FernandaItem Interacción gestual(Universidad de Cuenca, 2013-06) Parra González, Luis OttoItem 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 Diez principios de la gestión de proyectos que pueden ayudarte en tu profesión(Universidad de Cuenca, 2013-06) Mejía, XavierItem Sistemas de agua potable y aguas residuales de la ciudad de Cuenca(Universidad de Cuenca, 2013-06) Avila, RosaThis paper deals with the purification system that has the city of Cuenca and its surroundings, processes that have been described and shown the reliability and quality that are made. There is also an explanation of their treatment of wastewater from the city of Cuenca, a brief description of the various devices and machines that handle the process.Item Contaminación difusa producida por actividades agrícolas(Universidad de Cuenca, 2013-06) Avila, Juan; Reinoso, Paola; Zambrano, SandraWe can realize that today with the world’s growing population, human needs increase on a large scale, among these needs there is one very important for the development of the population such as feeding. This huge demand for food has led to develop techniques and technologies to improve the quality and quantity of the food production. However, the development of these new techniques and technologies has not only generated great benefits to mankind but has also caused a great increase in the pollution problem, causing degradation in the environment and in the public health. In agriculture, to increase and accelerate the production, have been made chemicals such as pesticides and fertilizers, many of these with great implications for water supplies that deteriorate ecosystems and change the water quality for human use. In some countries there is a control law, though in most countries there are not any regulations that make a control of the discharge limits, and it should be noted that agriculture is one of the few activities in which chemicals are deliberately discharged into the environment to destroying many form of life.Item Evolución de las bases de datos(Universidad de Cuenca, 2013-06) Zalamea, OlgaItem 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 El deslizamiento de la Josefina: "tragedia nacional"(Universidad de Cuenca, 2013-06) Zeas Domínguez, RodrigoItem 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 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 Enfoque básico del saneamiento ambiental(Universidad de Cuenca, 2013-06) Pacheco, Freddy; Once, David; Verdugo, JessicaToday, the theme of environmental quality and health of human beings is at risk due to environmental pollution, and lack of sanitation, it exists more in underdeveloped countries, existing problems caused by unhealthy lack of treatment in water, solid waste and excreta. This often happens due to lack of knowledge of people, how to treat the waste, so that this document will show what it’s about environmental health, so that citizens have an understanding on this issue and we note that these problems can be solved and we can prevent epidemics and major damage to humanity.Item 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 Estudio de selección de una arquitectura orientada a servicios (SOA), para ser implementada en el programa: manejo del agua y el suelo (PROMAS)(Universidad de Cuenca, 2013-06) Veintimilla, JaimeItem 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 Métodos para tratar el problema de la ubicación espacial de sitios compactos(Universidad de Cuenca, 2013-06) Vanegas Peralta, Pablo FernandoItem Nuestra "bala de plata"(Universidad de Cuenca, 2013-06) Ávila Ordóñez, Elina MaríaItem Control PID digital algoritmo, diseño e implementación(Universidad de Cuenca, 2013-06) Ochoa Correa, Danny Vinicio
