Brno - kompaktní město mezi starým a novým nádražím / Brno - Compact City among the old and the new railway stations

Tóth, Miroslav January 2010 (has links)
Urban planning and architectural study of a new section between the current and future railway station in Brno. The aim is to create a spatial concept of the urban environment as an alternative to the view, based on land-use plan. Plays an important role in building urban roller coaster as the main connecting element of the old and the new station. The solutions are used by the principles of making compact buildings. Optimal use of the area is provided by stacking functions. The concept is focused on the quality of housing is closely linked with the central character of public spaces. The main objective of this work is to extend the core of the city, supplementing the missing values of the old town (parking, green areas, transport structure) The basic concept of this work is to create a new district with high quality, but especially attractive housing. Unalterable feature of urban roller coaster, play a very important role in shaping the urban environment. The territory is held by the exposed area with quiet residential neighborhoods. The creation of pedestrian zones in the entire passage supports pedestrian and bicycle transportation in the city. Cars are restricted blind residential streets and reducing speed in residential zónach.Na other hand, ensured the flow of network communications reception. Svratky the river promenade is the nature of urban-type facilities for the sport. Character and location point of the amphitheater will open as landartový facility for leisure and outdoor activities, possibly the layout of interesting events with the use of the water surface.

Developing A Parcel-based Information System By Object-oriented Approach

Tufan, Emrah 01 December 2003 (has links) (PDF)
The cadastre contains parcel related data which must be up-to-date. The cadastral data in any country constitute a very big dataset. Therefore parcel related data should be carefully managed. Today, using a database is an effective way of data management. The relational database management system can be a good one for parcel related data. However when the information system concept is considered, just relational database management system is not enough. Some tools are needed in order to manipulate the data in the relational database management system. Object oriented analysis and design is a good choice to develop these tools. In this study, a parcel-based information system is developed and it is implemented for &Ccedil / ankaya Municipality. During the development relational database management system is used for attribute data management, and object-oriented analysis and design is used for development of application to manipulate the data in the relational database management system. The cadastral data are separated into two parts and each part is handled separately. The first part is the geographic or spatial data. These data are handled by the help of the MapInfo Professional Version 6.5. The other part is the attributes of these spatial data. For this part, relational database is designed and implemented on Microsoft SQL Server Version 2000. During the development of the relational database, conceptual database design is performed by enhanced entity-relationship (EER) model. Then in the logical design, the conceptual model is mapped into the relational model. After data storage area is created, the application is developed on that data by using principles of object-oriented design and analysis and unified modeling language. By the help of the software developed, the data management can be carried out easily. By this study, a solution is proposed for the cadastral data management problem of the municipalities, and this study is one of the first studies developed for parcel related data using object-oriented approach for municipalities.

Efeitos de poluição urbana na higroscopicidade dos aerossóis e na ativação de gotas em nuvens quentes na Amazônia no âmbito do experimento GoAmazon 2014/5 / Urban pollution effects on aerosols hygroscopicity and warm clouds droplets activation in Amazon in context of the GoAmazon 2014/5 experiment

Araujo, Alex Sandro Alves de 05 May 2017 (has links)
As medidas do experimento Green Ocean Amazon (GoAmazon 2014/5 ) foram realiza- das nos arredores de Manaus, na região central da Amazônia, durante dois anos, com o objetivo de entender como o ciclo de vida dos aerossóis e das nuvens em condições naturais é influenciado pelas emissões urbanas. Neste contexto, o presente trabalho procurou estudar a higroscopicidade dos aerossóis em condições poluídas pela pluma de Manaus e discuti-la à luz do que era esperado em condições prístinas. A partir desses resultados experimentais, usamos um modelo adiabático de parcela de nuvem para estudar o impacto da poluição de Manaus na formação de nuvens quentes. Observamos altas concentrações de aerossóis vindos de Manaus, com média de Ncn = 2.425 cm 3 e percentis de 25 % e de 75 % respectivamente dados por 937 cm 3 e 3.259 cm 3 . Para a Amazônia prístina, os valores tipicamente encontrados são da ordem de Ncn 400 cm 3 . A higroscopicidade das partículas da poluição urbana é notavelmente baixa, com média de t = (0, 09 ± 0, 01) para todos os diâmetros investigados. Além disso, são altamente heterogêneas quanto à higroscopicidade. As partículas naturais da Amazônia têm higroscopicidade média da ordem de t 0, 14, não sendo tão heterogêneas quanto as partículas de Manaus. Aperfeiçoamos e utilizamos um modelo adiabático de parcela de nuvem para investigar de forma sistemática o impacto da pluma de Manaus nos primeiros estágios de formação das nuvens quentes. O modelo foi validado através da comparação com quatro casos exemplificados na literatura, vindos de modelos conceitualmente semelhantes, mas de implementações numéricas diferentes. Em nossas simulações, consideramos que o formato da distribuição de tamanho das partículas de aerossol poderia variar com a concentração total de partículas, ao irmos da situação limpa para a poluída. Além disso, consideramos também que a higroscopicidade variava com a concentração total e com o tamanho das partículas de aerossol. Isto foi feito em etapas, permitindo representar as partículas de aerossol com crescente grau de detalhamento. Observamos que o número de gotículas na base da nuvem é determinado principalmente pela concentração de partículas e pela velocidade vertical. Em segundo lugar, vem o formato da distribuição de tamanho, e, depois, a higroscopicidade. Mostramos que simulações que não consideram estes outros fatores irão, necessariamente, superestimar o efeito dos aerossóis nas nuvens quentes. Da condição limpa para a condição poluída pela pluma, observamos o aumento da concentração gotículas e a correspondente diminuição do raio efetivo dessa população de gotículas. Observamos, também, a diminuição da fração de aerossóis ativados. Os resultados sugerem que, na condição poluída, as nuvens acumulam água líquida mais rapidamente em seus primeiros 200 m, em relação à condição limpa. / The measurements of the Green Ocean Amazon 2014/5 experiment were carried out on the outskirts of Manaus, in the central Amazon region, for two years, with the objective of understanding how the natural aerosol and cloud life cycles would be perturbed by urban emissions. In this context, the present work aimed at studying the aerosol hygroscopicity under polluted condition, comparing it with the pristine environment. Based on these results, we used an adiabatic cloud parcel model to study the impact of Manaus pollution on the first stages warm clouds formation. We observed high concentrations of aerosols coming from Manaus, with average Ncn = 2.425 cm 3 and percentiles 25 % and 75 % of 937 cm 3 and 3.259 cm 3 res- pectively. For the pristine Amazon, typical values would be about Ncn 400 cm 3 . The hygroscopicity of urban pollution particles were notable low, with average t = (0, 09±0, 01) for all diameters investigated, and a high level of heterogeneity was found. On the other hand, natural particles in the Amazon have a hygroscopicity of about t 0,14 and are not as much heterogeneous. We improved and used an adiabatic cloud parcel model to systematically investigate the impact of the Manaus pollution plume on the first stages of warm cloud develop- ment. The model was validated by comparison with four exemplary cases found in the literature, from conceptually similar models, but with different numerical imple- mentations. In our simulations, we considered that the shape of the size distribution could vary with increasing number concentration, as we moved from the clean to the polluted conditions. We also allowed the hygroscopicity to vary with the concentration and the diameter of the aerosol particles. These were done in stages, hence allowing an increasing level of complexity in the representation of the aerosol particles. We observed that the number of activated cloud droplets is as function primarily of the concentration and the vertical velocity. In second place comes the dependence with the shape of the size distribution and, after that, with the hygroscopicity. We showed that simulations that do not consider these other factors will, necessarily, over predict the effect of aerosols on shallow warm clouds. As expected, when we simulated clean conditions changing towards a polluted one, we found an increase in the number of activated droplets and corresponding decrease of effective radius of those droplets, and of the activated fraction. Our results suggest that, under polluted conditions, clouds accumulate liquid water more rapidly during the first stages of its development than under clean conditions.

Spatial and Temporal Dynamics: Residential Development Process

Park, Joung Im 2010 December 1900 (has links)
A lack of empirical evidence to understand neighborhood and residential development processes within neighborhoods has challenged urban planners’ ability to influence the course of future land development. The main objectives of this study were to examine neighborhood and residential development patterns and investigate dynamic processes in northwest Harris County, Texas, along the U.S. Highway 290 transportation corridor from 1945 to 2006. Researchers have identified different patterns of land development: leapfrog, contagion and infill development. However, because of the fuzziness in neighborhood and residential development patterns, the nominal classifications of development patterns are limited in their potential to characterize development patterns both on neighborhood and parcel levels; their applications for development processes and its impacts are even more limited. This study presents a quantitative approach for measuring development patterns by characterizing neighborhood development patterns as a function of spatial distance and temporal lapse time from the closest existing neighborhood to new neighborhood(s). The analysis in this study was based on disaggregated parcel data provided by the Harris County Appraisal District (HCAD) real estate and property records. The quantitative measures of neighborhood development patterns and processes within each pattern of neighborhood were derived by aggregating parcel level data into neighborhood level. This study developed the Long-term Trend of Development Model (LTDM) to classify neighborhood and residential development patterns based on spatial distance and temporal lapse time from existing neighborhoods to new neighborhood(s) each year to examine development processes. Regression analysis was used to identify the relationship between neighborhood patterns and residential development processes. This study found that development patterns can be measured quantitatively with spatial and temporal relationships between prior and new development at the neighborhood level. Empirical evidence supported the hypothesis that leapfrog neighborhood development triggers neighborhood development, contagion follows leapfrog neighborhood quickly, and infill follows contagion after a lapsed time. Residential development patterns in each pattern of neighborhood showed discrete development processes. Age of neighborhood can be used to predict development pressures and growth. In this process, physical and social infrastructure is involved, therefore, development process is best observed on the neighborhood level.
