Book excerpt: "En este trabajo se quiere proponer una metodología multiobjetivo que simultáneamente permita optimizar los costos de construcción de la red y la confiabilidad, destacando que es un problema que debe ser abordado desde la selección misma del trazado de la red, y por tal motivo va a ser posible determinar diferentes escenarios en los que se pueda construir una frontera de Pareto, con un algoritmo de ponderación de funciones objetivo. Esta frontera tendrá como ejes fundamentales el costo del diseño hidráulico y la confiabilidad de la red en cuestión." -- Tomado del Formato de Documento de Grado.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Existen diferentes programas que permiten realizar el diseño de sistemas de alcantarillados, UTOPÍA es un programa desarrollado por el Centro de Investigaciones en Acueductos y Alcantarillados de la Universidad de Los Andes (CIACUA). Este programa ha sido adaptado a diferentes ecuaciones de costo y de diseño, que tiene como propósito la optimización de la red a partir de la ruta más corta. metodología desarrollada por Bellman Ford. El programa no sólo busca minimizar los costos de la red, también debe cumplir con ciertas condiciones hidráulicas y de construcción, como los límites de excavación, relación de llenado de acuerdo con el diámetro de tubería, la velocidad mínima y la velocidad máxima. La investigación se centra en los efectos de modificar el límite de velocidad máxima, de acuerdo con los resultados, el diseño se ve afectado cuando en un terreno de alta pendiente (mayor al 8%) se restringe el límite de velocidad, ya aumenta de manera importante los límites de excavación, caso contrario en el que aumenta el límite de velocidad, en el cual se respetan los límites de excavación y se disminuyen los costos."--Tomado del Formato de Documento de Grado.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "La presente investigación se pretende verificar el comportamiento de los diseños de redes de drenaje urbano, haciendo uso de la metodología desarrollada previamente por el CIACUA de la Universidad de los Andes, con la cual se encuentra la mejor alternativa de manera exhaustiva en materia de costos y aspectos constructivos. Permitiendo así, llevar a cabo diseños optimizados en un sistema de drenaje urbano que se caracterice por tener altas pendientes en el terreno, y que incluya el uso de cámaras de caída estándar como alternativa de optimización. Aunado con lo anterior, al contar con diseños óptimos, se genera sostenibilidad de estos sistemas que usualmente se ven afectados por las altas fuerzas abrasivas del flujo que conducen y evitando sobrecargas que afecten a las poblaciones. Siendo lo anterior congruente con lo expuesto por la Ingeniera Andrea Marú en su trabajo publicado en el 2018, denominado como Diseño optimizado de tuberías en serie en sistemas de alcantarillado incluyendo estructuras de caída; con el cual fue propuesto un cambio a la metodología propuesta por Natalia Duque en el 2013, la cual consiste en la inclusión del módulo de cámaras de caída al programa de diseño óptimo para series de tuberías, el cual pertenece al CIACUA. Así las cosas, con la inclusión de cámaras de caída según sean requeridas en el marco del cumplimiento de las restricciones hidráulicas tales como velocidad máxima, se generan escenarios factibles de menor costo que aquellos donde no se tenga la posibilidad de crear cámaras de caída y la red deba profundizar en aras de cumplir con las restricciones de velocidad propuestas."--Tomado del Formato de Documento de Grado.

Download or read book Soil and Sediment Remediation written by Piet Lens and published by IWA Publishing. This book was released on 2005-09-30 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.
