Sectorization: measures and an electromagnetism based approach

Sectorization means dividing a set of basic units into sectors or parts, a procedure that occurs in several contexts, such as political, health and school districting, social networks and sales territory or airspace assignment, to achieve some goal or to facilitate an activity. This presentation will focus on three main issues: Measures, a new approach to sectorization problems and an application in waste collection. When designing or comparing sectors different characteristics are usually taken into account. Some are commonly used, and they are related to the concepts of contiguity, equilibrium and compactness. These fundamental characteristics will be addressed, by defining new generic measures and by proposing a new measure, desirability, connected with the idea of preference. A new approach to sectorization inspired in Coulomb’s Law, which establishes a relation of force between electrically charged points, will be proposed. A charged point represents a small region with specific characteristics/values creating relations of attraction/repulsion with the others (two by two), proportional to the charges and inversely proportional to their distance. Finally, a real case about sectorization and vehicle routing in solid waste collection will be mentioned.

The Influence of Propagation Model and Sectorization over WCDMA Capacity

In this paper we use a dynamic model that we have developed for WCDMA capacity analysis using MATLAB and a GIS based planning tool, to estimate the capacity of a mobile system under different conditions like number of cells, propagation model, sectorization and handover margin.

Waste collection routing-limited multiple landfills and heterogeneous fleet

This article deals with a real-life waste collection routing problem. To efficiently plan waste collection, large municipalities may be partitioned into convenient sectors and only then can routing problems be solved in each sector. Three diverse situations are described, resulting in three different new models. In the first situation, there is a single point of waste disposal from where the vehicles depart and to where they return. The vehicle fleet comprises three types of collection vehicles. In the second, the garage does not match any of the points of disposal. The vehicle is unique and the points of disposal (landfills or transfer stations) may have limitations in terms of the number of visits per day. In the third situation, disposal points are multiple (they do not coincide with the garage), they are limited in the number of visits, and the fleet is composed of two types of vehicles. Computational results based not only on instances adapted from the literature but also on real cases are presented and analyzed. In particular, the results also show the effectiveness of combining sectorization and routing to solve waste collection problems.

Electromagnetism based approach to Sector design in Waste Collection

For efficient planning of waste collection routing, large municipalities may be partitioned into convenient sectors. The real case under consideration is the municipality of Monção, in Portugal. Waste collection involves more than 1600 containers over an area of 220 km2 and a population of around 20,000 inhabitants. This is mostly a rural area where the population is distributed in small villages around the 33 boroughs centres (freguesia) that constitute the municipality. In most freguesias, waste collection is usually conducted 3 times a week. However, there are situations in which the same collection is done every day. The case reveals some general and specific characteristics which are not rare, but are not widely addressed in the literature. Furthermore, new methods and models to deal with sectorization and routing are introduced, which can be extended to other applications. Sectorization and routing are tackled following a three-phase approach. The first phase, which is the main concern of the presentation, introduces a new method for sectorization inspired by Electromagnetism and Coulomb’s Law. The matter is not only about territorial division, but also the frequency of waste collection, which is a critical issue in these types of applications. Special characteristics related to the number and type of deposition points were also a motivation for this work. The second phase addresses the routing problems in each sector: new Mixed Capacitated Arc Routing with Limited Multi-Landfills models will be presented. The last phase integrates Sectoring and Routing. Computational results confirm the effectiveness of the entire novel approach.

Casas modernas na orla marítima de João Pessoa 1960 a 1974

This paper studies modern houses built in the neighborhoods of Cabo Branco, Tambaú and Manaíra by the seafront in Joao Pessoa, built between 1960 and 1974. We start from the already widespread notion that Brazilian Modern Architecture was inspired by foreign ways, mainly European but also American here recast, adapted, often innovating repertoire and ideas received (Y. BRUAND, 2005; H. SEGAWA, 2002; C. E. COMAS, 2002; C. E. COMAS, 2002; M. M. ACAYABA e S. FICHER, 1982; M. B. C. ARANHA, 2008; F. C. L. LARA, 2001; R. V. ZEIN, 2005; L. E. AMORIM, 1999, C. V. STINCO, 2010). With this look, after a field study, we collected 61 specimens in the collection of the Central Archive of João Pessoa City Hall, in order to identify which reformulations, adaptations or innovations would exist in modern houses built along the coast in João Pessoa. As we try to analyze the houses by what the bibliography had suggested (G. C. ARGAN, 1992; L. CORBUSIER, 2002; C.E.D. e M. ADRIÀ, 2007; K. FRAMPTON, 1997; H. H. HITCHCOCK, 1976; L. BENEVOLO, 2004; R. DE FUSCO, 1992, N . PEVSNER, 2002; M. RAGON, 1986; B. RISEBERO, 1982; E. ROBBINS, 1997; W. J. R. CURTIS, 1982; V. SCULLY, 2003; B. ZEVI, 1984; D. DUNST, 1999; A. COLQUHOUN, 2002; R. WESTON, 2005; A. IÑAKI, 2006; J. PETER, 1994) the starting idea seemed to us not sufficiently developed. So we decided, first, to undertake a literature review comparing speech and image of modern houses most often cited by international and national literature, following a script freely inspired the Vitruvian triad: the functional and spatial (sectorization, guidance, spatiality, movement); constructive aspects (structural elements, modulation, deck, sealing), and aesthetic aspects (composition, apertures, ornaments) (Cap.1), then cast a look under this same route in 61 specimens obtained initially, trying to verify any specificities they would have (Cap.2). Failing to deepen the analysis of all these examples, we chose 10 projects which were redesigned and described in more detail to which we supplement with the aspects of place - location / lot location, access, axiality. (E. C. MAHFUZ, 2002; J. C. MIGUEL, 2000; E. C. CHEREGATI, 2007; M. COTRIM, 2007). (Cap. 3). The documentation and description resulting allowed us to approach some related questions about the canonical transcripts hybridizing, adoptions and any vernacular innovations of modern houses along the coast, We conclude that the appellants and anachronistic elements isolates found in each of the studied bind to the Brazilian Modern Architecture

Praça: lugar de lazer: relações entre características ambientais e comportamentais na Praça Kalina Maia Natal RN

Nowadays, the urban chaos brings some problems to the citizens such as mental fatigue, irritability and lack of attention, emphasizing the need for open urban spaces, capable to contribute to the restoration of physical and mental balance of people. By the variety of alternative uses available, many of them related to the stimulus of entertainment activities, the squares have been identified as restorative environments, especially by its potential as a place of leisure. In this context, the objective of this dissertation is to understand the use of the square as leisure environment, by a square in Natal RN, establishing the relationship between environmental and behavioral characteristics. More specifically, I attempt to identify the major activities that happen there, the people that develop them and the spatial and temporal configurations of this occupation. Among the 290 squares available in the city, the Kalina Maia Square was selected, which is located in the district of Lagoa Nova. The case study chosen was based on criteria relating to scale, shape, location on the urban environment, variability of uses and conservation status. In the study were used behavioral mapping place-centered and people-centered, behavior trace analysis and 14 interviews. The results show that the square is used by people from different ages and social classes, subdivided into groups with specific days and times. These users are usually engaged in activities related to various types of leisure, with sports predominance. The relationship between spatial configuration and behavior shows that there is a sectorization of uses, being possible to identify the environmental characteristics that most favor observed activities, especially in relation to shading and presence of furniture and equipment. Moreover, throughout the day it appears that the affordances inherent to the various fixed objects on the square are decoded differently by various categories of users, by giving them insights that help the development of leisure activities that characterize each group

Análise do desempenho hidroenergético de sistemas de abastecimento de água do município de Marabá

Análise do desempenho hidroenergético de Sistemas de Abastecimento de Água do Município de Marabá/PA, gerenciados pela Unidade de Negócios Tocantins (UNITO), da Companhia de Saneamento do Pará – COSANPA. O estudo foi realizado em 3 fases, tendo informações do Sistema Nacional de Informações sobre Saneamento (SNIS) e da COSANPA. Na fase 1 foi analisada a rotina operacional de abastecimento de água do sistema Nova Marabá - Cidade Nova (16.738 ligações) e do sistema Marabá Pioneira (2.093 ligações) no ano 2010, com ênfase nos volumes produzidos de água e no consumo e custo de energia elétrica; na Fase 2 foram determinados indicadores de desempenho hidroenergético; finalizando, na fase 3 é proposto procedimentos para a melhoria da gestão hidroenergética. Na pesquisa foi verificado que o volume total produzido de água de 15,8 milhões m³/ano requereu 8.817 MWh/ano, resultando em despesa de R$ 2 milhões/ano de energia elétrica, que foi o segundo maior item das despesas de exploração (32,2%) da COSANPA no município de Marabá. A despesa de energia elétrica por ligação foi de R$ 9,32/lig. ano e R$ 7,66/lig. ano nos sistemas da Nova Marabá – Cidade Nova e da Marabá Pioneira, respectivamente, com preço médio global do kWh consumido e despesa média de energia elétrica por metro cúbico de água produzido na Nova Marabá - Cidade Nova (0,23 R$/kWh e 0,14 R$ /m³) e da Marabá Pioneira (0,21 R$/kWh e 0,07 R$/m³), ocorrendo variação dos índices de intensidade energética (kWh/m³) nos SAA. Com o trabalho é proposto procedimentos para aumentar a eficiência do controle hidroenergético na operação dos sistemas, como setorização, macromedição, micromedição, automação, o que trará reflexos positivos na redução dos custos para o abastecimento de água no município de Marabá/PA.

Caracterização gfeológico-geotécnica aplicada a gestão de risco no gasoduto GASBOL, trecho Ipeúna/SP - Itirapina/SP

The pipelines are characterized by the great length and linearity, these enterprises are usually associated with the horizon of soil and decomposed rock and accidents in this system usually have high complexity. So this work proposes a study of geological and geotechnical characterization of approximately 40 km ² and a study of risk analysis along 18.3 km of gas pipeline GASBOL, in the municipalities of Ipeúna-SP and Itirapina-SP, in scale 1:25.000, besides correlation between studies. The method for geological and geotechnical characterization is based on physiographic integrated analysis technique, which is supported by literature research, observation and interpretation of satellite imagery (photointerpretation), correlation of products numerical model of ground, fieldwork. The method adopted for risk classification is based on preliminary analysis of hazards (APP) technique, which is identified the geological process, this feature is classified as the susceptibility of occurrence, and then classified as the possible consequence of the process, if this evolves. As a product of the research, we designed a map in 1:25,000 scale, containing a table of geological and geotechnical characteristics of the mapped drives, as well as sectorization risk in each section of the pipeline. Were mapped geological and geotechnical seven units in the study area, delimited in excerpts of which five are classified as high risk, totaling 1.1 km in length of 18.3 km total

Túneles en macizos calcáreos karstificados: impacto en las obras subterráneas de los fenómenos kársticos, su evaluación y tratamiento

En esta Tesis Doctoral se aborda un tema poco estudiado en el ámbito de los túneles y cuya problemática está basada en los riesgos e incertidumbres que representa el diseño y ejecución de túneles en macizos calizos karstificados. Mediante un estudio profundo del comportamiento de distintos casos reales de túneles en macizos kársticos calizos, aportando la realización de modelos y la experiencia constructiva del autor, se pretende proponer un procedimiento que permita sistematizar las actuaciones, investigación, evaluación y tratamiento en los túneles en karst, como herramienta básica para la toma de decisiones primarias correctas. Además, se proponen herramientas que pueden ayudar a mejorar el diseño y a decidir las medidas más eficientes para afrontar los problemas que genera el karst en los túneles, minimizando los riesgos para todos los actores, su probabilidad e impacto. Se profundiza en tres fases principales (que son referidas en la tesis en cuatro Partes): La INVESTIGACIÓN del macizo rocoso: La investigación engloba todas las actuaciones observacionales encaminadas a obtener el IK (Índice de Karstificación), así como las investigaciones necesarias mediante recopilación de datos superficiales, hidrogeológicos, climáticos, topográficos, así como los datos de investigaciones geofísicas, fotointerpretación, sondeos y ensayos geotécnicos que sean posibles. Mediante la misma, se debe alcanzar un conocimiento suficiente para llevar a cabo la determinación de la Caracterización geomecánica básica del macizo rocoso a distintas profundidades, la determinación del Modelo o modo de karstificación del macizo rocoso respecto al túnel y la Zonificación del índice de karstificación en el ámbito de actuación en el que se implantará el túnel. En esta primera fase es necesaria la correcta Definición geométrica y trazado de la obra subterránea: En función de las necesidades que plantee el proyecto y de los condicionantes externos de la infraestructura, se deben establecer los requisitos mínimos de gálibo necesarios, así como las condiciones de máximas pendientes para el trazado en alzado y los radios mínimos de las curvas en planta, en función del procedimiento constructivo y motivación de construcción del túnel (ferrocarril, carretera o hidráulico, etc...). Estas son decisiones estratégicas o primerias para las que se ha de contar con un criterio y datos adecuados. En esta fase, son importantes las decisiones en cuanto a las monteras o profundidades relativas a la karstificación dominante e investigación de las tensiones naturales del macizo, tectónica, así como las dimensiones del túnel en función de las cavidades previstas, tratamientos, proceso de excavación y explotación. En esta decisión se debe definir, conocida ya de forma parcial la geotecnia básica, el procedimiento de excavación en función de las longitudes del túnel y la clasificación geomecánica del terreno, así como sus monteras mínimas, accesos y condicionantes medioambientales, pero también en función de la hidrogeología. Se establecerá la afección esperable en el túnel, identificando en la sectorización del túnel, la afección esperable de forma general para las secciones pésimas del túnel. Con todos estos datos, en esta primera aproximación, es posible realizar el inventario de casos posibles a lo largo del trazado, para poder, posteriormente, minimizar el número de casos con mayores riesgos (técnicos, temporales o económicos) que requieran de tratamiento. Para la fase de EVALUACIÓN de la matriz de casos posibles en función del trazado inicial escogido (que puede estar ya impuesto por el proyecto, si no se ha podido intervenir en dicha fase), es necesario valorar el comportamiento teórico del túnel en toda su longitud, estudiando las secciones concretas según el tipo y el modo de afección (CASOS) y todo ello en función de los resultados de los estudios realizados en otros túneles. Se debe evaluar el riesgo para cada uno de los casos en función de las longitudes de túnel que se esperan que sean afectadas y el proceso constructivo y de excavación que se vaya a adoptar, a veces varios. Es importante tener en cuenta la existencia o no de agua o relleno arcilloso o incluso heterogéneo en las cavidades, ya que los riesgos se multiplican, así mismo se tendrá en cuenta la estabilidad del frente y del perímetro del túnel. En esta segunda fase se concluirá una nueva matriz con los resultados de los riesgos para cada uno de los casos que se presentarán en el túnel estudiado. El TRATAMIENTO, que se debe proponer al mismo tiempo que una serie de actuaciones para cada uno de los casos (combinación de tipos y modos de afección), debiendo evaluar la eficacia y eficiencia, es decir la relevancia técnica y económica, y como se pueden optimizar los tratamientos. Si la tabla de riesgos que se debe generar de nuevo introduciendo los factores técnicos y económicos no resulta aceptable, será necesaria la reconsideración de los parámetros determinados en fases anteriores. Todo el desarrollo de estas tres etapas se ha recogido en 4 partes, en la primera parte se establece un método de estudio e interpretativo de las investigaciones superficiales y geotécnicas, denominado índice de karstificación. En la segunda parte, se estudia la afección a las obras subterráneas, modelos y tipos de afección, desde un punto de vista teórico. La tercera parte trata de una recopilación de casos reales y las consecuencias extraídas de ellos. Y finalmente, la cuarta parte establece los tratamientos y actuaciones para el diseño y ejecución de túneles en macizos kársticos calizos. Las novedades más importantes que presenta este trabajo son: El estudio de los casos de túneles realizados en karst calizo. Propuesta de los tratamientos más efectivos en casos generales. La evaluación de riesgos en función de las tipologías de túnel y afecciones en casos generales. La propuesta de investigación superficial mediante el índice de karstificación observacional. La evaluación mediante modelos del comportamiento teórico de los túneles en karst para casos muy generales de la influencia de la forma, profundidad y desarrollo de la karstificación. In this doctoral thesis is studied the recommended investigation, evaluation and treatment when a tunnel is planed and constructed in karstic calcareous rock masses. Calcareous rock masses were selected only because the slow disolution produces stable conduct and caves instead the problems of sudden disolutions. Karstification index (IK) that encompasses various aspects of research karstic rock mass is presented. The karst rock masses are all unique and there are no similarities between them in size or density cavities ducts, but both their formation mechanisms, like, geological and hydrogeological geomorphological evidence allow us, through a geomechanical survey and geological-photo interpretation in the surface, establish a karst evaluation index specific for tunnelling, which allows us to set a ranking of the intensity of karstification and the associated stadistic to find caves and its risk in tunnelling. This index is estimated and useful for decision-making and evaluation of measures to be considered in the design of a tunnel and is set in degrees from 0 to 100, with similar to the RMR degrees. The sectorization of the tunnel section and the types of condition proposed in this thesis, are estimated also useful to understand the different effects that interception of ducts and cavities may have in the tunnel during construction and service life. Simplified calculations using two-dimensional models contained in the thesis, have been done to establish the relationship between the position of the cavities relative to the section of the tunnel and its size in relation to the safety factors for each ground conditions, cover and natural stresses. Study of over 100 cases of tunnels that have intercepted cavities or karst conduits have been used in this thesis and the list of risks found in these tunnels have been related as well. The most common and effective treatments are listed and finally associated to the models and type of affection generated to give the proper tool to help in the critical decision when the tunnels intercept cavities. Some existing studies from Marinos have been considered for this document. The structure of the thesis is mainly divided 4 parts included in 3 steps: The investigation, the evaluation and the treatments, which match with the main steps needed for the critical decisions to be made during the design and construction of tunnels in karstic rockmasses, very important to get a successfully project done.
