O trabalho tem por principal objetivo verificar, preliminarmente, a possibilidade de reduzir a quantidade de indivíduos na amostra de Pesquisa de Entrevistas Domiciliares, sem prejudicar a qualidade e representatividade da mesma. Analisar a influência das características espaciais e de uso de solo da área urbana constitui o objetivo intermediário. Para ambos os objetivos, a principal ferramenta utilizada foi o minerador de dados denominado Árvore de Decisão e Classificação contido no software S-Plus 6.1, que encontra as relações entre as características socioeconômicas dos indivíduos, as características espaciais e de uso de solo da área urbana e os padrões de viagens encadeadas. Os padrões de viagens foram codificados em termos de sequência cronológica de: motivos, modos, durações de viagem e períodos do dia em que as viagens ocorrem. As análises foram baseadas nos dados da Pesquisa de Entrevistas Domiciliares realizada pela Agência de Cooperação Internacional do Japão e Governo do Estado do Pará em 2000 na Região Metropolitana de Belém. Para se atingir o objetivo intermediário o método consistiu em analisar, através da Árvore de Decisão e Classificação, a influência da variável categórica Macrozona, que representa as características espaciais e de uso de solo da área urbana, nos padrões de viagens encadeadas realizados pelos indivíduos. Para o objetivo principal, o método consistiu em escolher, aleatoriamente, sub-amostras contendo 25% de pessoas da amostra final e verificar, através do Processamento de Árvores de Decisão e Classificação e do teste estatístico Kolmogorov - Smirnov, se os modelos obtidos a partir das amostras reduzidas conseguem ilustrar bem a freqüência de ocorrência dos padrões de viagens das pessoas da amostra final. Concluiu-se que as características espaciais e de uso de solo influenciam os padrões de encadeamento de viagens, e portanto foram incluídas como variáveis preditoras também nos modelos obtidos a partir das sub-amostras. A conclusão principal foi a não rejeição da hipótese de que é possível reduzir o tamanho da amostra de pesquisas domiciliares para fins de estudo do encadeamento de viagens. Entretanto ainda são necessárias muitas outras verificações antes de aceitar esta conclusão. / The main aim of this work is to verify, the possibility of reducing the sample size in home-interview surveys, without being detrimental to the quality and representation. The sub aim of this work is to analyze the influence of spatial characteristics and land use of an urban area. For both aims, the main analyses tool used was Data Miner called the Decision and Classification Tree which is in the software S-Plus 6.1. The Data Miner finds relations between trip chaining patterns and individual socioeconomic characteristics, spatial characteristics and land use patterns. The trip chaining patterns were coded in terms of chronological sequence of trip purpose, travel mode, travel time and the period of day in which travel occurs. The analyses were based on home-interview surveys carried out in the Belém Metropolitan Area in 2000, by Japan International Cooperation Agency and Pará State Government. In order to achieve the sub aim of this work, the method consisted of analyzing, using the Decision and Classification Tree, the influence of the categorical variable \"Macrozona\", which represents spatial characteristics and urban land use patterns, in trip chaining patterns carried by the individuals. Concerning the main aim, the method consisted of choosing sub-samples randomly containing 25% of the final sample of individuals and verifying (using Decision and Classification Tree and Kolmogorov-Smirnov statistical test) whether the models obtained from the reduced samples can describe the frequency of the occurrence of the individuals trip chaining patterns in the final sample well. The first conclusion is that spatial characteristics and land use of the urban area have influenced the trip chaining patterns, and therefore they were also included as independent variables in the models obtained from the sub-samples. The main conclusion was the non-rejection of the hypothesis that it is possible to reduce the sample size in home-interview surveys used for trip-chaining research. Nevertheless, several other verifications are necessary before accepting this conclusion.

Ce mémoire de maîtrise présente une nouvelle approche non supervisée pour détecter et segmenter les régions urbaines dans les images hyperspectrales. La méthode proposée n ́ecessite trois étapes. Tout d’abord, afin de réduire le coût calculatoire de notre algorithme, une image couleur du contenu spectral est estimée. A cette fin, une étape de réduction de dimensionalité non-linéaire, basée sur deux critères complémentaires mais contradictoires de bonne visualisation; à savoir la précision et le contraste, est réalisée pour l’affichage couleur de chaque image hyperspectrale. Ensuite, pour discriminer les régions urbaines des régions non urbaines, la seconde étape consiste à extraire quelques caractéristiques discriminantes (et complémentaires) sur cette image hyperspectrale couleur. A cette fin, nous avons extrait une série de paramètres discriminants pour décrire les caractéristiques d’une zone urbaine, principalement composée d’objets manufacturés de formes simples g ́eométriques et régulières. Nous avons utilisé des caractéristiques texturales basées sur les niveaux de gris, la magnitude du gradient ou des paramètres issus de la matrice de co-occurrence combinés avec des caractéristiques structurelles basées sur l’orientation locale du gradient de l’image et la détection locale de segments de droites. Afin de réduire encore la complexité de calcul de notre approche et éviter le problème de la ”malédiction de la dimensionnalité” quand on décide de regrouper des données de dimensions élevées, nous avons décidé de classifier individuellement, dans la dernière étape, chaque caractéristique texturale ou structurelle avec une simple procédure de K-moyennes et ensuite de combiner ces segmentations grossières, obtenues à faible coût, avec un modèle efficace de fusion de cartes de segmentations. Les expérimentations données dans ce rapport montrent que cette stratégie est efficace visuellement et se compare favorablement aux autres méthodes de détection et segmentation de zones urbaines à partir d’images hyperspectrales. / This master’s thesis presents a new approach to urban area detection and segmentation in hyperspectral images. The proposed method relies on a three-step procedure. First, in order to decrease the computational complexity, an informative three-colour composite image, minimizing as much as possible the loss of information of the spectral content, is computed. To this end, a non-linear dimensionality reduction step, based on two complementary but contradictory criteria of good visualization, namely accuracy and contrast, is achieved for the colour display of each hyperspectral image. In order to discriminate between urban and non-urban areas, the second step consists of extracting some complementary and discriminant features on the resulting (three-band) colour hyperspectral image. To attain this goal, we have extracted a set of features relevant to the description of different aspects of urban areas, which are mainly composed of man-made objects with regular or simple geometrical shapes. We have used simple textural features based on grey-levels, gradient magnitude or grey-level co-occurence matrix statistical parameters combined with structural features based on gradient orientation, and straight segment detection. In order to also reduce the computational complexity and to avoid the so-called “curse of dimensionality” when clustering high-dimensional data, we decided, in the final third step, to classify each individual feature (by a simple K-means clustering procedure) and to combine these multiple low-cost and rough image segmentation results with an efficient fusion model of segmentation maps. The experiments reported in this report demonstrate that the proposed segmentation method is efficient in terms of visual evaluation and performs well compared to existing and automatic detection and segmentation methods of urban areas from hyperspectral images.

The aim of this Diploma Thesis is constructionally - technological solution of the rough construction of polyfunctional house on the corner of Bánskobystrická and Medlánecká streets in Brno Řečkovice. In the Diploma Thesis I will deal with the plan of the work procedure of the execution of roof construction layers, machine sets, itemized budget, construction schedule, construction site equipment, inspection and testing plan, ecology and transport relations related to the construction. I would like to point out the complication of the construction with a lack of space because the construction is in the area of Brno Řečkovice. The plan of construction execution was more difficult due to lack of space for storage of materials and machinery handling.

Bro is an urban area located in Upplands-Bro municipality, Stockholm County. In 2020, the Stockholm Police conducted a security survey for all municipalities included in the Stockholm police region. The results of the survey for Upplands-Bro municipality show that many residents feel insecure about the risk of being exposed to crime. The residents experience that the feeling of insecurity is at its highest in Bro. The thesis is limited to investigating this in nine public spaces in central Bro. The purpose is to investigate whether previously crime-prone public spaces in built-up environments can evoke experiences of insecurity in people, despite their unawareness that they are old crime scenes. If people experience insecurity, the thesis aims to investigate which crime prevention measures can be applied in the design of public spaces to increase their security experiences there. In the essay, the student is named as the "investigator". The approach to the thesis applies several different methods. A safety survey is the thesis' main method, while a safety walk (method combination) is the secondary one. Initially, site analyzes are used as feasibility studies to carry out several site visits in the nine public spaces. (1) The first site visit is made to get to know the existing conditions of the sites and to create an overall picture. At the same time, the places are photographed in daylight. (2) Site visit no. 2 is made to photograph the sites in the evening darkness. (3) During the third site visit, the investigator conducts a safety walk, where a focus group of eight members (excluding the investigator) consisting of residents in Bro, is invited for interviews in the field. The intention with this is to take part in their experiences if the places feel unsafe and if there is a need for crime prevention measures to achieve increased security. (4) Site visit no. 4 is made to study in detail the spatial properties of the sites on the basis that the focus group has identified “insecurity problems” that are most in need of crime prevention measures for increased security. The crime prevention measures in the thesis include: (1) increased care of the outdoor environment, cutting shrubs and trees, (2) repairing broken materials, repainting, (3) removal of damage, graffiti and debris, (4) increased lighting, (5) to open up the site, remove dark spaces/hiding places, (6) increase the view of the site from buildings or through direct human supervision, (7) to add electrical safety systems such as camera surveillance/alarm/gate code or fences around the site. A safety survey is conducted with the intention of reaching out to all residents in the urban area of Bro. The survey mainly asks questions about: (1) how they experience security at the nine sites and (2) whether the sites need to be changed for increased security there, which creates a need for crime prevention measures. The questionnaire is sent out in collaboration with Upplands-Bro municipality's Street / Park / Traffic department and 247 locals answer the questionnaire. However, the response rate does not correspond to all of Bros' urban residents, which the investigator is aware of. To include all residents, the investigator has not requested biological sex or age in all methods. Thus, the investigator has disregarded what a possible distribution of answers between women and men or different age groups can look like. The answers from the safety walk and the survey are analyzed through qualitative content analysis. The method results are made visible in the form of photographs and diagrams with accompanying descriptive text about the results with the highest percentage that are perceived to be most prominent. The results are then visualized in an insecurity map, a form of heat map. The insecurity map is compared with the crime scene map to see if there is a connection between “unsafe places” and “previous crime scenes” in a combined map. In the analysis, the survey results are interpreted through the thesis' theoretical perspective and validated against the outcome of the safety walk. Based on the analysis, the investigator reads out what crime prevention measures residents point out to achieve increased security in the "unsafe places". Then the results are discussed and how they fulfill the purpose of the essay and answer the problem formulation and the questions. Finally, conclusions and recommendations for future studies are presented.

Reconstruction in the central urban area. Design public urban space objects with new restaurant, the city market and a printer object conversion. Objects and area will contain all the necessary functions associated with the movement of visitors and movement of pasants. An important part of the solution will transform the river embankment. This is a broader vision of the future and possibilities of urban centers with the potential of finding the historical core.

Parmi les formes d’organisation de l’habitat antique, il en est une qui est longtemps restée en retrait dans la recherche archéologique française. Les agglomérations antiques, qui correspondent à des formes très variées d’habitat groupé, suscitent un intérêt majeur depuis une vingtaine d’années.L’étude historiographique, à l’échelle de la Gaule, fait ressortir un espace en marge des recherches, celui des cités du Massif central. Cette thèse propose donc d’étudier les agglomérations antiques des cités arverne, vellave, gabale, rutène, cadurque et lémovice entre le Ier s. av. J.-C. et le Ve s. ap. J.-C. Les objectifs sont multiples. Il a été nécessaire dans un premier temps d’établir un corpus de sites à partir de la bibliographie régionale. Celui-ci est composé de notices normalisées au sein desquelles l’ensemble des données actuellement disponibles a été présenté. Pour répondre aux questions d’organisation spatiale et de classification, les données bibliographiques recueillies, complétées par des opérations de terrain (prospections terrestres, aériennes, géophysiques, relevés topographiques), ont été synthétisées à partir d’une série de descripteurs archéologiques développés sur le modèle d’Archaeomedes. L’emploi de ces descripteurs a permis la mise en œuvre d’analyses statistiques multivariées afin de dépasser le simple classement par niveaux de fiabilité (sites rejetés, agglomérations hypothétiques, agglomérations avérées). C’est sur la base de la classification retenue après différents tests et sur la hiérarchie urbaine proposée que les analyses spatiales et morphologiques permettent de brosser un tableau complet de l’armature urbaine des cités antiques du Massif central.Les résultats obtenus ont permis d’exposer et de comprendre à la fois les relations entre les agglomérations et le milieu naturel mais aussi avec leur environnement archéologique par l’étude de leurs relations avec l’habitat rural, les chefs-lieux, les limites des cités, leur territoire théorique, les axes de communications terrestres et fluviaux. En changeant d’échelle, l’analyse interne des agglomérations permet d’appréhender à la fois leur morphologie générale mais aussi la place des édifices monumentaux au sein des agglomérations et au sein des cités, le rôle de l’artisanat, les aménagements hydrauliques, … Pour l’analyse de l’armature urbaine, la thèse prend nécessairement en compte l’évolution chronologique des agglomérations à travers leur origine protohistorique, leur évolution durant l’Antiquité et leur devenir au début du Moyen Âge.Pour mener à bien ce travail, il a été nécessaire de croiser les approches documentaires (bibliographie, opérations de terrains), de croiser les échelles d’analyse (du site au Massif central) et de comparer les résultats à ceux des régions voisines. Passées, les analyses statistiques, c’est à partir d’un SIG et d’une base de données que l’ensemble des synthèses a pu être mené.Cette thèse constitue la première synthèse sur les agglomérations antiques des cités du Massif central. Les résultats mettent en avant l’importance des agglomérations dans le système de peuplement et des armatures urbaines variables entre les cités mais qui semblent structurées en partie par le relief et les axes de communications. Les fonctions présentes au sein des agglomérations, si elles sont variées et récurrentes, montrent des spécificités entre les cités mais aussi une hétérogénéité au sein de chacune d’elles. Enfin, l’analyse chronologique montre une réduction du nombre des agglomérations à partir du IIIe siècle mais pas leur disparition. De même, de nouvelles formes d’habitats groupés apparaissent à partir du IVe siècle attestant non pas une crise mais une évolution dans l’organisation urbaine des cités pour répondre à de nouveaux besoins. / Among the forms of organization one can observe in the ancient habitat, there is one particular structure that has been slightly ignored by French archeologists: the lesser urbanized settlements. However, in the last twenty years, small towns have attracted renewed interest.A historiographical study of the Gaul territory highlighted a less studied group of population: the ancient peoples of the Massif Central. In this thesis we intend to have a closer look at such populations as the Arvernes, the Vellaves, the Gabales, the Rutenes, the Cadurques, and the Lemovices from 1st century B.C. - 5th century A.D. We first established a corpus of sites starting with the study of the regional bibliography, which enabled us to create records for each area. We completed this first approach with several field operations such as ground, aerial, geophysical and topographical surveys. All those data were synthesized in a series of archaeological descriptors developed using the Archaeomedes model.The use of such descriptors enabled us to develop some statistical analyses and go beyond the simple reliability factor (which allows the distinction between rejected sites, hypothetical and true urbanized clusters). On the basis of our tested and proven classification, keeping in mind the suggested urban hierarchy and with the help of our spatial and morphological analyses, we were able to obtain a more complete picture of the urban framework of the ancient cities of the Massif Central.The data collected allowed us to better apprehend and understand the relation between such urban clusters and their natural environment, but also to place them in an archaeological context by studying the links between rural housing, the ancient administrative structure (chef-lieu), the city and territory limits, and the major communication routes (land and water). Through a multi-scale study of those population clusters, we were able to determine their general structure, to look at the role of local crafts and trade but also the place of major buildings, and waterworks. We took specific care to the chronological evolution in thosesmall towns by looking at them from their protohistoric beginnings through Antiquity and until early medieval times.While we cross-referenced all the different sources (bibliography and field surveys) and the analysis scales within the Massif Central, we also did a cross-comparison with other neighboring areas in order to validate such work. Besides the statistical data, we used the Geographic Information System and our database to reach our conclusions.This thesis aims at uncovering the reality of those ancient population clusters present in the Massif Central. Our results showed clearly the importance of those in the settlement system, their different forms structured according to the local geography and major trade routes. The functions/positions available in small towns were varied and recurrent but also corresponded to specific trades within each structure while remaining homogeneous.Through our chronological analysis we were able to point out a significant reduction in their numbers starting in the third century, though not their disappearing. In the 4th century new types of population clusters appeared, not as a response to an acute crisis, but more as a result of an evolution called on by new needs.

The subject of the diploma thesis is the architectural study of the mix-used urban housing situated closed to the Brno city centre. The design will allow mixing of greater amount of different functions on a relatively small built-up area, which will reduce the requirements on transport and provide the inhabitant with various forms of housing, services and employment. The mass and spatial solution respects the surrounding city blocks on south and the mass increase to the north industrial zone. The mass defines the area and respect noise protection zone on housing development. The shape of object's ground plan is based on the area, which is divided by four axes of pedestrian paths. The basic matter of object is divided into four blocks linked by common internal square. The mass solution provides private, semi-private and public courtyards.

The theme of the diploma thesis "Brno waterfront - rehabilitation of the Brno rivers and their surroundings" is creating an urban proposal in Brno, Zábrdovice, on the eastern waterfront of the Svitava river. The intention is to use the potential of the area and create the possibility of lucrative housing by river with a commercial ground floor, services, leisure time park with a multifunctional playground and easy direct access to the Svitava river. The studied location, has an area of 6.32 hectares andis defined mainly by the Zábrdovická Street and the Svitava River near the former Premonstratensian Monastery, which now serves as a Military Hospital. At present, the location has mainly low-floor industrial buildings with storage and expedition functions. The proposed buildings relate to existing buildings on the east and west banks of the Svitava River. They have the form of four to six storey blocks, which are characteristic for this area. The park connects to the revitalized eastern embankment of the river at the site of a new footbridgethat connects both rive sides and stairs. They provide space formeetings and relaxation, but also serve as a flood control in the event of a water inflow. Along the Svitava River there is a sidewalk with street alleyways and access to the river.

The territory is located in the city of Brno, district Trnitá on the embankment of the river Svitava. The subject of the diploma thesis is the architectural study of the design of the urban spatial structure with intensive use of city urban area, designed in pre-diploma project, which preceded diploma thesis. The design will allow mixing of greater amount of different functions on a relatively small built-up area, which will reduce the requirements on transport and provide the inhabitant with various forms of housing, services and employment. The shape of object's ground plan is based on area, which is connected from three sides to access roads. The mass and spatial solution respects the surrounding buildings and uses existing bike trails and sidewalks in the southeastern part of the area. The basic matter of object is divided by three axes passing through the building, into three blocks linked by common internal block. This creates a square with a tree-lined atrium with seating under the trees. The shape of these three blocks is further formed by removing of the mass, which results into forming of atriums, terraces and balconies, which brings natural light into the interior while allowing illumination of the patio and surrounding buildings within the territory. This spatial structure is horizontally divided by functions. Designed here are underground public garages, passages with shops, services, administration / commerce and housing. Despite the diversity of functions, for the facade was chosen a unified character of white horizontal lines contrasting with the dark gray lines of windows and facade cladding.

The aim of this thesis is a revitalization of the grounds once belonging to Zbrojovka Brno. These grounds are in the zoning map defined as “brownfield”. Within Brno’s limits, the area has an extremely convenient location. Since the grounds are situated in the central part of Brno, the complex is in terms of traffic and transport in the vicinity of both, the current and the newly planned ring-road. Important factors influencing the project are the river Svitava which borders the west side of the area, and a railroad corridor skirting the east side of the location. Assigned area was, for the purposes of this thesis, expanded by the grounds once belonging to Zetor and the adjoining area towards Markéty Kuncové Street. Several buildings from the former grounds, which fit in into the urban concept and were in good technical conditions, have been preserved. From a functional point of view, the newly designed grounds will meet all the requirements for a fully independent municipal district. The multifunctional development contains primarily housing complexes, administrative buildings, public facilities, recreational areas, as well as other functional structures. The urban concept of this project is a result of a study of surrounding blocks. Based on an analysis of the size and height of these buildings, an idealized block was designed and then recreated into a symmetrical raster of blocks with the street width of 20m. This raster was subsequently applied to newly designed points of entry into the area. Total urban and mass proposal of the development areahas been further influenced by principal conceptual points. Among these conceptual points belong the perspective axes which connect the conceptual points with an orientation point, in this case the former factory’s smokestack. Creating a new arm for the Svitava River is another point. Taking into account that the whole vicinity of the factory grounds is without quality public greenery elements.
