A cartografia ambiental de síntese: procedimentos e aplicações para o município de Limeira - SP / Environmental mapping of synthesis: procedures and applications for the city of Limeira - SP

Lima, Fredy Ravazzi 31 August 2010 (has links)
O município de Limeira SP enfrentou um crescimento urbano intenso e desordenado, após a segunda metade do século XX, oriundo dos incentivos públicos de descentralização industrial da capital paulista, que provocou grandes problemas socioambientais. O presente estudo procura analisar as fragilidades e potencialidades da organização do espaço em Limeira através da metodologia da Cartografia Ambiental de Síntese, pois esta possibilita a delimitação de unidades individualizadas da paisagem a partir da síntese dos atributos físicos e sociais presentes no espaço. Para tanto, foi realizado um levantamento bibliográfico dos principais conceitos e metodologias dos estudos ambientais na Geografia, dando destaque à Cartografia e aos novos instrumentos de coleta e manipulação de dados espaciais. Em seguida, foram coletadas informações sobre o município através de pesquisa bibliográfica, imagens de satélite e trabalhos de campo. Estas informações foram organizadas no software SPRING para a confecção dos mapas temáticos e do mapa ambiental de síntese. De posse do mapa final foi possível analisar cada unidade de paisagem isoladamente segundo seus atributos, podendo servir de suporte a outros estudos no município e para a administração pública a fim de subsidiar um planejamento territorial mais compatível com a realidade local. / The county of Limeira - SP faced an intense and disorganized urban growth, since the second half of the twentieth century, due to the industrial decentralization of the state capital, by government incentives, which caused major social and environmental problems. This study seeks to analyze the weaknesses and strengths of the space organization in Limeira through the methodology of Environmental Synthesis Cartography, since this enables the delineation of individual units of landscape from the synthesis of physical and social attributes present in the space. For this, we carried out a literature review of the main concepts and methodologies of environmental studies in Geography, focusing on the Cartography and the new spatial data collection and manipulation instruments. Then, we collected information on the county through literature search, satellite images and field work. This information was organized in the SPRING software to elaborate thematic maps and the final environmental synthesis map. In possession of the final map it became possible to parse each landscape unit separately according to their attributes, providing a support to other studies in the county and to the government in creating a territorial planning more compatible with local realities.

Protection of Karst spring in Shanxi Region,China: A case study from Jinci Spring Catchment.

Zhang, Zhixiang January 2019 (has links)
Philosophiae Doctor - PhD / Groundwater is an important of water resources and plays a significant role in the water supply in most parts of the world. It is also an important ecological environment factor, and its variations often affect natural balance of the ecosystem. China is one of the few countries in the world where Karst is intensively developed Karst water is heavily utilized as water supply source. Shanxi is such a province with largest Karst distribution in places in North China, where 19 large Karst springs and their catchment are identified to provide an important source of the water supply and ecosystem functioning in Shanxi

Coupled spring equations

Fay, TH 01 January 2003 (has links)
Summary Coupled spring equations for modelling the motion of two springs with weights attached, hung in series from the ceiling are described. For the linear model using Hooke’s Law, the motion of each weight is described by a fourthorder linear differential equation. A nonlinear model is also described and damping and external forcing are considered. The model has many features that permit the meaningful introduction of many concepts including: accuracy of numerical algorithms, dependence on parameters and initial conditions, phase and synchronization, periodicity, beats, linear and nonlinear resonance, limit cycles, harmonic and subharmonic solutions. These solutions produce a wide variety of interesting motions and the model is suitable for study as a computer laboratory project in a beginning course on differential equations or as an individual or a small-groupundergraduate research project.

Investigation of thermal spring back of a hot formed 22MnB5 A-pillar with tailored properties

Lugnberg, Mattias, Netz, Tobias January 2016 (has links)
In a world where fuel economy and crash safety is becoming an important factor in the automotive industry, the need for materials with very high strength-to-weight ratio is growing rapidly. One of the materials used for this purpose is the boron steel 22MnB5. Since the material has very high mechanical yield limit it is hard to produce parts using cold forming, which is the standard procedure for sheet metal forming. Therefore, the use of hot stamping is increasing. Hot stamping enables manufacturing of boron steel parts with good dimensional accuracy and low spring back. However, some amount of spring back is still present during the process. In this thesis, spring back of a hot formed 22MnB5 A-pillar is investigated using computer simulations in the software LS-DYNA. The main focus was to develop a process for simulating spring back in hot stamping. The work started with simulations of the forming and quenching stages of the hot stamping process, both on a full size and on a smaller section of the blank. Simultaneously as the simulations, a literature study was also conducted. The literature study was aimed at finding hints and information on how to build the simulations. Furthermore, interviews were made with experts on both LS-DYNA and hot stamping. A process for spring back evaluation was then created and written as an LS-DYNA keywordfile. In the developed spring back simulation, the part is taken out of the press right after the quenching is finished and placed in a space where it can cool and move freely. The simulation is conducted until the part reaches room temperature. After the quenching is done, data containing temperatures, stresses and strains of the part is exported. This data is then included in the spring back simulation where the part is cooled to room temperature. During the cooling, the stresses, strains and temperatures are equalized until the spring back reaches a steady state. The results indicate that the developed method for spring back evaluation can be used to foresee shape deviations for the intended part and process.
