Résumé :
Abstract. The morphological segmentation of binary patterns provides an effective method for characterising spatial patterns with emphasis on connections between their parts as measured at varying analysis scales. The method is widely used for the analysis of landscape patterns such as those related to the fragmentation of forests or other natural land cover classes. This can be explained by its effectiveness at capturing the complexity of binary patterns and their connections by partitioning the foreground pixels of the corresponding binary images into mutually exclusive classes. While the principles of the method are conceptually simple, the definition of the classes relies on a series of advanced mathematical morphology operations whose actual implementation is not straightforward. In this paper, we propose an open source code for MSPA and detail its main components in the form of pseudo-code. We demonstrate its effectiveness for asynchronous processing of tera-pixel images and the synchronous exploratory analysis and rendering with Jupyter notebooks.

Résumé :
Conservation areas are essential for preserving green spaces and biological diversity. Although previous studies have demonstrated that spatial optimization techniques are effective for balancing the relationship between ecological importance and spatial pattern during conservation practices, the design of ecological corridors still requires an efficient, intelligent, and flexible workflow. In addition, functional connectivity information is usually unavailable or very difficult to obtain. To alleviate these problems, this paper has developed a new spatial optimization-based model that combines morphological spatial pattern analysis (MSPA) with ecological importance assessment. The consideration of MSPA can guarantee enough ecological corridors in the conservation plan, while the regions with higher ecological importance can be discovered through an ecological importance assessment. This method has been applied to the planning of conservation areas in a highly developed city. Several experiments have indicated that our proposed model could achieve much better performance than conventional models in terms of spatial pattern. Therefore, this new model is expected to assist decision processes during the planning and regulation of green spaces in fragmented urban ecosystems. Furthermore, it can be applied to ecological management and planning in many other aspects because the above-mentioned research gaps are not unique to only Asian or less-developed countries.

Résumé :
Madagascar is a biodiversity hotspot, containing a large proportion of endemic species. To make conservation efforts more effective, it is necessary to understand the spatial distribution of this huge biodiversity. In this study, the patterns of morphological variation and diversity in the adult anurans of Madagascar were evaluated and compared across different climatic regions. These patterns were investigated for 370 species (2360 specimens), and the variation in 13 morphological traits obtained from taxonomic databases was assessed. The results revealed differences in body size distribution across climatic regions and that the most morphologically distinctive species occur in humid regions. The analysis also showed that anuran assemblages tend to be more species-rich, more morphologically diverse, and more morphologically clustered in tropical rainforests. These patterns are attributable to regional variations in the amount and seasonality of precipitation. An understanding of the complex patterns of spatial diversity could be useful for regional prioritization in the conservation of Madagascan anurans.

Résumé :
High-density urban areas have spatial characteristics, such as complex functions, population gathering, and complex forms, that lead to more severe urban heat island effects. Systematically evaluating the thermal environmental benefits of urban spatial forms to optimize the urban physical environment is important. In this study, Tianjin’s central urban area, which is a typical representative of high-density urban areas, was selected to invert the multi-period land surface temperature by relying on the existing two- and three-dimensional morphological data set of communities. The multi-scale geographically weighted regression model was used to fit the regression relationship between the urban land surface temperature and spatial morphological parameters. From this, the influencing factors of different types of existing community spaces and their spatial stabilities were explored. The results show the following: (1) The summer surface temperature varies greatly in the central urban area, and the high-temperature areas are mainly distributed in the industrial, residential, and commercial districts. (2) The MGWR model has the better model-fitting ability. The positive influence coefficients of temperature include ISP and BD, while the negative influence coefficients are BSD, BH, NDVI, and SVF. (3) There is significant spatial heterogeneity in the impact coefficients among the blocks that can be targeted to mitigate the heat island effect. This study provides ideas for optimizing the spatial morphological parameters of surface temperature in urban centers. Future challenges include increasing the spatial morphological parameter selection range, dissecting the interactive relationships between spatial morphological parameters and their effectiveness on the surface temperature, and refining the study’s spatial and temporal granularity.

Résumé :
Current approaches applied in the historical analysis on the morphological evolution of early Malay towns primarily focused on describing how cities were formed and transformed without much emphasis on how they can be analysed. Considering cities as urban organisms experiencing rapid growth, achieving a sustainable urban transition would be impossible without understanding the process of initial formation and spatial uniqueness that comprise the Malay town. However, analysing the particular kind of processes requires a comprehensive understanding of each hierarchical level of morphological elements, which, therefore, posed a greater challenge in excerpting Malay town's dynamic and organic growth pattern-development. This study attempt to develop the methodological process of urban morphological analysis framework concerning the Malay town context. With the adoption of the historic-geographical approach as the method of analysis, the study applied two different spatial scales as the basis of the analysis process, that is, plan-units analysis and morphological evolution analysis. The findings unveiled the inherent morphogenesis processes of Malay towns central to the spatial structure of Kota, represent a town that functioned as a territorial base with settlements of Kampung as the archetype of the morphological unit. Through depicting the spatial boundary of Dalam Kota and Luar Kota, the fixation line of the growth process in Malay town can be identified, which is imperative to the functioning system of the town. Accordingly, developing the systematic morphological analysis process aids in providing a clear and responsive strategy for managing the changing process of Malay towns to ensure a sustainable transition for resilient communities and territories

Résumé :
The present paper develops a general methodology for the morphological segmentation of hyperspectral images, i.e., with an important number of channels. This approach, based on watershed, is composed of a spectral classification to obtain the markers and a vectorial gradient which gives the spatial information. Several alternative gradients are adapted to the different hyperspectral functions. Data reduction is performed either by Factor Analysis or by model fitting. Image segmentation is done on different spaces: factor space, parameters space, etc. On all these spaces the spatial/spectral segmentation approach is applied, leading to relevant results on the image.

Résumé :
The North Krembangan area is an old city area in Surabaya, right next to the Kalimas River. This area has experienced several changes from time to time, both in terms of natural context, roads, blocks/lots, and buildings. These changes were influenced by several factors and actors, both from the Dutch government and from the Surabaya government due to the existence of several new needs that were no longer relevant in the conditions during the colonial era. Objectives: To identify the morphology of urban tissue in the North Krembangan area which consists of permanent, non-permanent elements and street front quality Methodology and Results: This research uses the urban tissue methodology by Romice et al as a theory that helps to analyze this area. Conclusion, Significance and Implications: This research found that although the North Krembangan area has relatively low street front quality, this area is still busy and active as a commercial center. Suggestions to improve the area were also made at the end of this research.

Abstract In the following paper, the analyses of morphology of settlements were conducted using graph methods. The intention of the author was to create a quantifiable and simple measure, which, in a quantitative way, would express the degree of development of a graph (the spatial pattern of settlement). When analysing examples of graphs assigned to a set of small towns and large villages, it was noticed that the graph development index should depend on: a relative number of edges in relation to the number of nodes (β index), the number of cycles (urban blocks), which evidences the complexity of the spatial pattern of settlement, and the average rank of nodes of a graph, which expresses the degree of complexity of a street network.

Résumé :
Abstract Following the publication of ‘European Spatial Development Perspective’ in 1999, a large number of theoretical and empirical studies have been carried out on polycentric spatial development especially in European settlements. The relationship between polycentricity and economic competitiveness, environmental sustainability and social cohesion are some of the main concerns of these studies. This study aims to clarify ‘the meaning of polycentricity’ in the case of Turkey, as a developing country and analyse the relationship between polycentric spatial development and economic competitiveness, environmental sustainability and social cohesion. After calculation of morphological polycentricity of the regions at NUTS-5 level, the propositions on the positive effects of polycentric spatial development on economic competitiveness, environmental sustainability and social cohesion is tested by using Pearson correlation and OLS regression models. The results of the empirical study are mixed for these three subjects. Polycentric spatial development has not positive effects on economic competitiveness and social cohesion in Turkey case. Conversely, a positive effect exists in terms of environmental sustainability. It can be said, that to reach those policy aims highlighted by European Spatial Development Perspective, could not be realised by only taken into account polycentric spatial development in Turkey case.

Résumé :
L’objectif principal de ce travail est d’optimise la tomographie par coupe sériée dans un microscope ‘FIB’, en utilisant soit l’imagerie électronique du microscope à balayage (tomographie FIB-MEB), soit la diffraction des électrons rétrodiffusés (tomographie dite EBSD 3D). Dans les 2 cas, des couches successives de l’objet d’étude sont abrasées à l’aide du faisceau ionique, et les images MEB ou EBSD ainsi acquises séquentiellement sont utilisées pour reconstruire le volume du matériau. A cause de différentes sources de perturbation incontrôlées, des dérives sont généralement présentes durant l'acquisition en tomographie FIB-MEB. Nous avons ainsi développé une procédure in situ de correction des dérives afin de garder automatiquement la zone d'intérêt (ROI) dans le champ de vue. Afin de reconstruction le volume exploré, un alignement post-mortem aussi précis que possible est requis. Les méthodes actuelles utilisant la corrélation-croisée, pour robuste que soit cette technique numérique, présente de sévères limitations car il est difficile, sinon parfois impossible de se fier à une référence absolue. Ceci a été démontré par des expériences spécifiques ; nous proposons ainsi 2 méthodes alternatives qui permettent un bon alignement. Concernant la tomographie EBSD 3D, les difficultés techniques liées au pilotage de la sonde ionique pour l'abrasion précise et au repositionnement géométrique correct de l’échantillon entre les positions d'abrasion et d’EBSD conduisent à une limitation importante de la résolution spatiale avec les systèmes commerciaux (environ 50 nm)3. L’EBSD 3D souffre par ailleurs de limites théoriques (grand volume d'interaction électrons-solide et effets d'abrasion. Une nouvelle approche, qui couple l'imagerie MEB de bonne résolution en basse tension, et la cartographie d'orientation cristalline en EBSD avec des tensions élevées de MEB est proposée. Elle a nécessité le développement de scripts informatiques permettant de piloter à la fois les opérations d’abrasion par FIB et l’acquisition des images MEB et des cartes EBSD. L’intérêt et la faisabilité de notre approche est démontrée sur un cas concret (superalliage de nickel). En dernier lieu, s’agissant de cartographie d’orientation cristalline, une méthode alternative à l’EBSD a été testée, qui repose sur l’influence des effets de canalisation (ions ou électrons) sur les contrastes en imagerie d’électrons secondaires. Cette méthode corrèle à des simulations la variation d’intensité de chaque grain dans une série d’images expérimentales obtenues en inclinant et/ou tournant l’échantillon sous le faisceau primaire. Là encore, la méthode est testée sur un cas réel (polycritsal de TiN) et montre, par comparaison avec une cartographie EBSD, une désorientation maximale d'environ 4° pour les angles d’Euler. Les perspectives d’application de cette approche, potentiellement beaucoup plus rapide que l’EBSD, sont évoquées
The aim of current work is to optimize the serial-sectioning based tomography in a dual-beam focused ion beam (FIB) microscope, either by imaging in scanning electron microscopy (so-called FIB-SEM tomography), or by electron backscatter diffraction (so-called 3D-EBSD tomography). In both two cases, successive layers of studying object are eroded with the help of ion beam, and sequentially acquired SEM or EBSD images are utilized to reconstruct material volume. Because of different uncontrolled disruptions, drifts are generally presented during the acquisition of FIB-SEM tomography. We have developed thus a live drift correction procedure to keep automatically the region of interest (ROI) in the field of view. For the reconstruction of investigated volume, a highly precise post-mortem alignment is desired. Current methods using the cross-correlation, expected to be robust as this digital technique, show severe limitations as it is difficult, even impossible sometimes to trust an absolute reference. This has been demonstrated by specially-prepared experiments; we suggest therefore two alternative methods, which allow good-quality alignment and lie respectively on obtaining the surface topography by a stereoscopic approach, independent of the acquisition of FIB-SEM tomography, and realisation of a crossed ‘hole’ thanks to the ion beam. As for 3D-EBSD tomography, technical problems, linked to the driving the ion beam for accurate machining and correct geometrical repositioning of the sample between milling and EBSD position, lead to an important limitation of spatial resolution in commercial softwares (~ 50 nm)3. Moreover, 3D EBSD suffers from theoretical limits (large electron-solid interaction volume for EBSD and FIB milling effects), and seems so fastidious because of very long time to implement. A new approach, coupling SEM imaging of good resolution (a few nanometres for X and Y directions) at low SEM voltage and crystal orientation mapping with EBSD at high SEM voltage, is proposed. This method requested the development of computer scripts, which allow to drive the milling of FIB, the acquisition of SEM images and EBSD maps. The interest and feasibility of our approaches are demonstrated by a concrete case (nickel super-alloy). Finally, as regards crystal orientation mapping, an alternative way to EBSD has been tested; which works on the influence of channelling effects (ions or electrons) on the imaging contrast of secondary electrons. This new method correlates the simulations with the intensity variation of each grain within an experimental image series obtained by tilting and/or rotating the sample under the primary beam. This routine is applied again on a real case (polycrystal TiN), and shows a max misorientation of about 4° for Euler angles, compared to an EBSD map. The application perspectives of this approach, potentially faster than EBSD, are also evoked

Résumé :
In tropical and sub-tropical regions, whiteflies are common pests causing severe losses on food-crops and a threat to food-security. I the sub-tropics, a critical issue is the lack of spatial information about whiteflies. Moreover, outdated information is available about the current status of their parasitoid fauna. On the contrary, in the tropics no or incomplete information is available regarding the diversity of whiteflies and their parasitoids. Methods: Morphological, molecular and geostatistical methods were used to assess the whitefly and parasitoid fauna on herbaceous plants in a subtropical environment (Sicily) and in the tropics (Tanzania). Morphological techniques were adopted first to identify specimens. Moreover, molecular markers were used to confirm cryptic species. Bio-climatic aspects have been taken into account in the aim to understand which factors influence the spread of whitefly pest species. For this reason, diversity and distributional information was first accumulated to build a database. The database was then analyzed by Geographical Information System for (i) mapping richness and abundance, (ii) modeling the potential distribution of a pest species and (iii) revealing zones for parasitoid reserve selection. Finally, we showed how elevation gradient can be an additional instrument to study the cryptic species Principal findings: In Sicily, a measure of the current status of whitefly and parasitoid fauna was given. Nine whitefly species were identified: Aleurolobus marlatti, Aleurothrixus floccosus, Aleyrodes elevatus, Aleyrodes proletella, Bemisia afer, Bemisia tabaci, Dialeurodes citri, Trialeurodes lauri and T. vaporariorum. Moreover, three cryptic species were identified in the B. tabaci species complex: B. tabaci Mediterranean, B. tabaci Middle East-Asia 1 and B. tabaci Italy. Modelling the potential distribution of these major whitefly pests at regional scale revealed suitable areas where they can occur. A striking finding in this study was the replacement of the exotic invader B. tabaci Middle East Minor 1 by the B. tabaci Mediterranean species, which is at present the predominant. Another important finding was the fact that the elevational gradient functions as a filter, selecting the species of B. tabaci group. As for the parasitoid fauna, nine species were identified belonging to the genera Encarsia and Erermocerus. A reserve selection model permitted to identify two main areas that seem to function as reservoir for whitefly parasitoids. In Tanzania the diversity of whitefly species infesting cassava and other herbaceous plants was investigated. Ten whitefly species were identified: Aleurodicus dispersus; Aleurothrixus floccosus; B. tabaci species group (B. tabaci Sub-Saharan Africa 1, B. tabaci Mediterranean and B. tabaci Indian Ocean); B. afer, Bemisia sp. (formerly Asterobemisia sp.), Dialeurodes citri, Paraleyrodes bondari and T. vaporariorum. The potential distribution of super-abundant B. tabaci was modelled, revealing the presence of suitable areas extending also further to neighbouring countries such as Zambia. Moreover, unsuitable area was identified serving as an environmental barrier and avoiding the spread of the pest to the south-eastern part of the country. Six Encarsia, four Eretmocerus and one Cales species were identified, adding more species to the previous list of parasitoids recorded in East-Africa and discovering of a probable new species of Eretmocerus. For the first time En. mineoi and En. sp. pr. circumsculpturata were recorded in Tanzania. Parasitoids have been detected at very low numbers, showing the occurrence of a relatively scarce natural enemies complex. Conclusions: The research presented here documents the whitefly and parasitoid fauna colonizing herbaceous plants in the two sites chosen, respectively tropical and sub-tropical regions. Combining the methods mentioned above was useful in understanding the diversity and distribution of these insects.

Résumé :
From a global point of view, as argued by Levy (1999), the modern city has undergone radical changes in its physical form, either in terms of territorial expansion as well as in terms of interna! physical transformations. Today, approximately 75% of the European population lives in urban areas ,which makes the urban fulure of the conlinent a major cause of concern (Brazil, Cavalcanti, & Longo, 2014). lndeed, the demand for urban land, both within and around the cities, is becoming increasingly acule (European Environmenl Agency, 2006). Ouring the last decades, also Spain has been undergoing an important process of urban growth, which has implied the consumption of a large amounl of land, al hough the overall population growth rale, mostly along certain specific geographic areas, has remained at least unchanged or even, in sorne cases, il has also decreased. Such a phenomenon has been quite remarkable along the Mediterranean side. As argued by Gaja (2008), the urban development in Spain has been strongly linked to the model of economic development , which relies, since its launch in the 50's, onlhree main factors , i.e.:emigration, building, and mass tourism. Nowadays , in Spain, and mostly along the Medilerranean side, several urban areas are facing important phenomena of urban sprawl, also feared by he European Union. An accurate information about the pattern of land use/land cover, over time, is a fundamental requirement for a better understanding of the urban models. Currently, even though plenty of approaches to the image classification, through Remote Sensing (RS) techniques, have been advanced, Land Cover/Land Use classification is still an exciting challenge (Weng, 2010). Actually, the increasing development of RS and GIS technologies, during the last decades, has provided further capabiliies for measuring, analysing, understanding, modelling the "physical expressions" of urban growth phenomena, either in terms of pattern and process (Bhatta, 2012), and based on land use/land cover mapping and change delection over time. Based on such a technological approach, here we first aim to set up a suitable methodology for detecting generalized land cover classes based on an assisted automatic (or semi-aulomatic) pixel-based approach, calibrated upon Landsat Thematic Mapper (TM) mullispectral imagery, at 30 meters of spatial resolution. Beside, through the use of Geographical lnformation Syslem (GIS) we provide a spatial analysis and modelling of different urban models, from a morphological standpoint, in order to define the main pattern of land occupation al municipal scale, and along the Mediterranean side of Spain, al the year 2011. We focus on two main issues. On one hand, RS techniques have been used to set up a proper semi-automatic classification methodology, based on the use of Landsat imagery, capable of handling huge geographical areas quickly and efficiently. This process is basically aimed to detect the urban areas, at the year 2011, along the Mediterranean side of Spain, depending on the administrative division of Autonomous Communities. On the other hand, the spatial patterns of urban settlements have been analysed by using a GIS platform for quantifying a set of spatial metrics about the urban form. Hence, once get the quantification of different morphological features, including the analysis aboul either the urban profile, the urban texture, and the street network pattern, an automatic classification of different urban morphological models has been proposed, based on a stalistical approaches, namely factor and cluster analysis
Desde un punto de vista global,como sostiene Levy (1999), la ciudad moderna ha experimentado cambios radicales en su forma física, ya sea en términos de expansión territorial, así como en términos de transformaci ones internas. Hoy en día, aproximadamente el 75% de la población europea vive en zonas urbanas, lo que hace del futuro urbano delcontinente, una causa importante de preocupación (Brasil, Cavalcanti, y Longo, 2014). De hecho, la demanda de suelo urbano, dentro y alrededor de las ciudades , es cada vez más aguda (Agencia Europea de Medio Ambiente,2006). Durante las últimas décadas, también España ha experimentado un importante proceso de crecimiento urbano que ha implicado el consumo de una gran cantidad de tierra, aunque la tasa de crecimiento de la población en general, sobre todo a lo largo de ciertas áreas geográficas específicas , se ha mantenido al menos sin cambios o incluso, en algunos casos, también ha disminuido. Este fenómeno ha sido muy evidente a lo largo de la vertiente mediterránea. Como sostiene Gaja (2008), el desarrollo urbano en España se ha visto fuertemente vinculado con el modelo de desarrollo económico, que se basa, desde su lanzamiento en la década de los 50,en tres factores principales, a saber: la emigración, la construcción y el turismo de masas. Hoy en día, en España, y sobre todo a lo largo de la vertiente mediterránea, varias zonas urbanas se enfrentan a fenómenos importantes de expansión urbana, también temidos por la Unión Europea. Al respecto,un requisito fundamental para mejorar la comprensión y el estudio de los modelos urbanos es obtener en eltiempo una información precisa sobre los patrones de cubiertas y uso de suelo. Actualmente, a pesar de la existencia de numerosos métodos para la clasificación de imágenes digitales a través de técnicas de teledetección, para ext raer información sobre cobertura/uso de suelo, este enfoque sigue siendo un reto apasionante (Weng, 2010). El creciente desarrollo de las tecnologías de RS y GIS, durante las últimas décadas, ha proporcionado nuevas capacidades para medir, analizar, comprender, y modelar las "expresiones físicas" de los fenómenos de crecimiento urbano, en términos de patrones y procesos (Bhatta, 2012), y con base en el mapeo y análisis de cambios de cobertura/uso de suelo a través el tiempo. Basándose en un enfoque tecnológico, el primero objetivo es establecer una metodología adecuada para la detección de clases de cobertura de la tierra generalizadas que encuentra su fundamento en una asistido automático (o semiautomático), enfoque basado en píxeles, calibradas en Landsat Thematic Mapper (TM) imágenes multiespectrales, a 30 metros de resolución espacial. Al lado, a través del uso del Sistema de Información Geográfica (SIG), es posible proveer un análisis espacial y la modelización de diferentes modelos urbanos, desde un punto de vista morfológico, con el fin de definir el patrón principal de la ocupación del suelo a escala municipal a lo largo de la vertiente mediterránea de España, en el año 2011. En particular no enfocamos en dos cuestiones principales. Por un lado, las técnicas de RS se han utilizado para establecer una metodología de clasificación semi-automático adecuada, basada en el uso de imágenes Landsat, capaz de manejar grandes zonas geográficas de forma rápida y eficiente. Este proceso, básicamente, va dirigido a detectar las áreas urbanas, en el año 2011, a lo largo de la vertiente mediterránea de España, según la división administrativa de las Comunidades Autónomas. Por otro lado, los patrones espaciales de asentamientos urbanos han sido analizados mediante el uso de una plataforma GIS para cuantificar un conjunto de métricas espaciales sobre la forma urbana. Finalmente, una vez obtenida la cuantificación de diferentes características morfológicas, se ha proporcionado una clasificación automática de los diferentes modelos morfológicos urbanos, basada en un enfoque estadístico, es decir, análisis factorial y clúster.

Résumé :
L'histopathologie a pour objectif d'analyser des images de tissus biologiques pour évaluer l’état pathologique d'un organe et établir un diagnostic. L'apparition des scanners de lames a haute résolution a ouvert la voie a des nouvelles possibilités d'acquisition de très grandes images (whole slide imaging), de multiplexage de marquages, d'extraction exhaustive d'informations visuelles et d'annotations multiples a large échelle. Cette thèse propose un ensemble de méthodes algorithmiques visant a faciliter et optimiser ces différents aspects. Dans un premier temps, nous proposons une méthode de recalage multiculturelle d'images histologiques multi-marquées reposant sur les propriétés des B-splines pour modéliser, de fawn continue, une image discrète. Nous proposons ensuite de nouvelles approches d'analyse morphologique sur des polygones faiblement simples, généralisés par des graphes a segments droits. Elles reposent sur le formalisme des squelettes droits (une approximation de squelettes courbes définis par des segments droits), construits a l'aide de graphes de motocyclettes. Cette structure permet de réaliser des opérations de morphologie mathématiques sur des polygones avec une complexité réduite. La précision des opérations sur des polygones bruites est obtenue en raffinant la construction des squelettes droits par ajout adaptatif de sommets. Nous avons aussi propose un algorithme de détection de l'axe médian et montre qu'il est possible de reconstruire la forme d'origine avec une approximation arbitraire. Enfin, nous avons explore les squelettes droits pondérés qui permettent des opérations morphologiques directionnelles. Ces approches d'analyse morphologique offrent un support consistant pour améliorer la segmentation des objets grâce a l'information contextuelle et réaliser des études liées a l'analyse spatiale des interactions entre les différentes structures d’intérêt au sein du tissu. Tous les algorithmes proposes sont optimises pour le traitement d'images gigapixels et garantissent une reproductibilité des analyses, notamment grâce a la création du plugin Icytomine, interface entre Icy et Cytomine
Histopathology aims to analyze images of biological tissues to assess the pathologi¬cal condition of an organ and to provide a diagnosis. The advent of high-resolution slide scanners has opened the door to new possibilities for acquiring very large im¬ages (whole slide imaging), multiplexing stainings, exhaustive extraction of visual information and large scale annotations. This thesis proposes a set of algorith¬mic methods aimed at facilitating and optimizing these different aspects. First, we propose a multi-scale registration method of multi-labeled histological images based on the properties of B-splines to model, in a continuous way, a discrete image. We then propose new approaches to perform morphological analysis on weakly simple polygons generalized by straight-line graphs. They are based on the formalism of straight skeletons (an approximation of curved skeletons defined by straight segments), built with the help of motorcycle graphs. This structure makes it possible to perform mathematical morphological operations on polygons. The precision of operations on noisy polygons is obtained by refining the construction of straight skeletons. We also propose an algorithm for computing the medial axis from straight skeletons, showing it is possible to approximate the original polygonal shape. Finally, we explore weighted straight skeletons that allow directional mor¬phological operations. These morphological analysis approaches provide consistent support for improving the segmentation of objects through contextual information and performing studies related to the spatial analysis of interactions between dif¬ferent structures of interest within the tissue. All the proposed algorithms are optimized to handle gigapixel images while assuring analysis reproducibility, in particular thanks to the creation of the Icytomine plugin, an interface between Icy and Cytomine

Résumé :
Nous nous intéresserons dans cette thèse à l'étude et la caractérisation des Textures Dynamiques (TDs), avec comme application visée l'indexation dans de grandes bases de vidéos. Ce thème de recherche étant émergent, nous proposons une définition des TDs, une taxonomie de celles-ci, ainsi qu'un état de l'art. La classe de TD la plus représentative est décrite par un modèle formel qui considère les TDs comme la superposition d'ondes porteuses et de phénomènes locaux. La construction d'outils d'analyse spatio-temporelle adaptés aux TDs est notre principale contribution. D'une part, nous montrons que la transformée en curvelets 2D+T est pertinente pour la représentation de l'onde porteuse. D'autre part, dans un objectif de décomposition des séquences vidéos, nous proposons d'utiliser l'approche par Analyse en Composantes Morphologiques. Notre contribution consiste en l'apport et l'étude de nouvelles stratégies de seuillage. Ces méthodes sont testées sur plusieurs applications: segmentation spatio-temporelle, décomposition de TDs, estimation du mouvement global d'une TD, ... Nous avons de plus montré que l'Analyse en Composantes Morphologiques et les approches multi-échelles donnent des résultats significatifs pour la recherche par le contenu et l'indexation de Textures Dynamiques de la base de données DynTex. Cette thèse constitue ainsi un premier pas vers l'indexation automatique de textures dynamiques dans des séquences d'images, et ouvre la voie à de nombreux développements sur ce sujet nouveau. Enfin, le caractère générique des approches proposées permet d'envisager leurs applications dans un cadre plus large mettant en jeu par exemple des données 3D.

Résumé :
Eliot Glacier is a small (1.6 km2), relatively well-studied glacier on Mount Hood, Oregon. Since 1901, glacier area decreased from 2.03 ± 0.16 km2 to 1.64 ± 0.05 km2 by 2004, a loss of 19%, and the terminus retreated about 600 m. Mount Hood's glaciers as a whole have lost 34% of their area. During the first part of the 20th century the glacier thinned and retreated, then thickened and advanced between the 1940s and 1960s because of cooler temperatures and increased winter precipitation and has since accelerated its retreat, averaging about 1.0 m a-1 thinning and a 20 m a-1 retreat rate by 2004. Surface velocities at a transverse profile reflect ice thickness over time, reaching a low of 1.4 m a-1 in 1949 before increasing to 6.9 ± 1.7 m a-1 from the 1960s to the 1980s. Velocities have since slowed to about 2.3 m a-1 , about the 1940 speed.

Résumé :
Порцеляновий жовчний міхур є рідкісним проявом хронічних захворювань жовчного міхура, характеризується кальцифікацією своєї стінки і зустрічається у 0,06-0,8% холецистектомій [4]. За повідомленнями різних авторів кальцифікація стінки жовчного міхура (ЖМ) асоціюється з раком жовчного міхура (РЖМ) у 12-61% випадків [1, 2]. За результатами різних досліджень, у 0-62% випадків пацієнти з ПЖМ виникає рак жовчного міхура. Метою нашої роботи був морфологічний аналіз 3 клінічних випадків порцелянового жовчного міхура. Матеріали і методи. Впродовж 2012-2014 років у хірургічному відділенні Сумської обласної клінічної лікарні перебувало 3 хворих жінок (58, 66 та 64 років), у яких був виявлений порцеляновий жовчний міхур. У роботі були використані рутинні гістологічні і гістохімічні методики. Результати дослідження. Загальною рисою макропрепаратів жовчних міхурів був сіруватий або білувато-рожевий колір, щільна консистенція стінок і збереження форми органа. Макропрепарат першого випадку мав вигляд «порцелянового глечика», який мав ригідні стінки, не спадався при пальпації. На розрізі стінка жовчних міхурів потовщена до 1,0-1,2 см. Мінералізовані ділянки слизової оболонки були білувато-жовтавого кольору, гладенькі, блискучі та тверді. При механічному втручанні слизова оболонка відшаровувалася у вигляді тонких мінералізованих пластинок. На поверхні кальцифікованої слизової оболонки виявлялися тріщини, подібні до таких, які бувають на порцеляновому або полив'яному посуді. Гістологічне дослідження ПЖМ показує у всіх досліджуваних випадках у слизовій оболонці виявлялась помірна змішаноклітинна запальна інфільтрація. Депозити сполук кальцію відкладалися переважно у м’язовому шарі. Кальцифіковані маси розміщувалися вздовж м’язових та сполучнотканинних волокон, формували біомінеральні утворення в діапазоні від дрібних піскоподібних до грубо дисперсних фрагментів. Також виявлялися ознаки фіброзу, м’язової гіпертрофії, застою, крововиливи, гіалінозу. Висновок. У нашому дослідженні серед трьох клінічних випадків ПЖМ (один повний та два неповних типи) раку жовчного міхура не було виявлено. Ґрунтуючись на результатах досліджень та аналізу сучасних джерел літератури, можна зробити висновок, що біомінеральні утворення значних розмірів і поширеності у стінці жовчного міхура є відносно прогностично сприятливими і не асоціюються з раком жовчного міхура.
There are two types o f porcelain gallbladder, depending on the calcification degree: complete (covers the entire body, penetrates the muscle layer) and incomplete (multifocal, point deposits) \ The combination of gallbladder cancer and porcelain gallbladder with incomplete calcification type, according to various data, is ranging between 0 and 5% 2. There was no information about the combination of complete type of porcelain gallbladder and malignant tumors. This can indicate that two types o f calcification cause different risk of gallbladder cancer development.The aim o f our work was to evaluate the morphological haracteristics o f GB wall and to compare them with the results, which were obtained during the study o f other GB pathologies with mineralization. Materials and methods Ethics Statement. A written informed consent was obtained from all subj ects. This research was approved by the Medical Ethics Committee o f The Regional Clinical Hospital o f Sumy and Medical Institute o f Sumy State University (Protocol No.1, 14.01.14). Sample collection There were 3 female patients (1,2, 3 case — respectively 58, 66 and 64 years old) in the surgical department of Sumy Regional Hospital during 2012-2014 years. Porcelain gallbladder was revealed in these patients. All patients were routinely hospitalized with a diagnosis o f cholelithiasis and chronic calculous cholecystitis. All 3 cases o f PGB are estimated as random clinical findings. Research results Gallbladder macropreparations differed in the degree o f the spread o f the biomineralization processes in the wall of the organ, ranging from the calcification of large areas of the gallbladder wall (more than 50% o f the wall in the second case and 70% of the wall in the third case) to the total wall calcification (the first case). The common features o f gallbladders’ macropreparations were grayish or whitish-pink color, firm walls’ texture and save of the organ’s form. Macropreparation of the first case looked like a «porcelain ju g» , which has a rigid wall, did not drop during the palpation. The gallbladder wall is thickened to 1.0-1.2 cm at the section. Mineralized areas of mucous membrane were whitish-yellowish color, smooth, shiny and hard. During the mechanical intervention the mucous membrane exfoliated as thin mineralized plates. On the surface o f the calcified mucous membrane cracks, which were similar to those that can be in porcelain or glazed crockery, were detecteHistological examination o f the gallbladder shows typical pathological changes in organ’s tissues. In the mucous membrane o f all investigated cases moderate chronic inflammatory infiltration was detected. Deposits of calcium compounds deposited mainly in the muscular layer. Calcified mass located along the muscle and connective tissue fibers, formed biomineral formation ranging from small sand like to roughly dispersed fragments. Also the signs o f fibrosis, muscular hypertrophy, congestion, hemorrhage, hyalinosis were found. Conclusion. Gallbladder cancer was not found in our study of three clinical cases of PBC (one full and two partial types). Based on research and analysis o f modern literature sources, we can conclude that biomineral formations in considerable size and distribution in the gallbladder are relatively prognostic favorable and they are not associated with gallbladder cancer.

Résumé :
AbstractWe present the methodology employed for the study of an architectural type within the Lisbon Metropolitan Area spanning over eight hundred years with two chief epochs of exponential growth and commonly referred today as the gated community. Covering the use of remote sensing, georeferencing, data scraping, contemporary census, early modern period population counts, spatial disaggregation, spatial analytics, network analysis and new network-based socio-urban measures, the methodology offers a single semi-automated design for the reproducible urban analysis of a metropolitan area, culminating with the production of eight urban models covering periods from the late XVI to the early XXI centuries. Evaluation carried out on the models through statistical analysis and probabilistic unsupervised learning methods shows the resurgence of morphological and socio-urban patterns separated in time by centuries of urban development.

Résumé :
AbstractThe focus of this volume is speciesism. While the concepts of species and speciation remain the focus of a great deal of research, it is worth exploring how in recent decades evolutionary biology has, in several ways, moved away from species as the key unit of analysis of biological questions. I begin by outlining how phylogenetic comparative methods have become essential methodological tools in statistical analyses of relationships between traits. Species are not statistically independent observations, because the reality is that they are related, genetically and statistically, on a phylogenetic tree. Phylogeny also plays a key role in modern analyses of spatial patterns in biodiversity, and in fact relying on phylogenetic biodiversity measures can avoid a number of problems created by attempting to impose a uniform species rank across different continents and clades. Similarly, a major challenge in modern studies of diversification and extinction concerns the units of analysis and how they are defined and recognized. Both “genus” and “species” are human-defined ranks imposed on the phylogenetic tree. The phylogenetic tree is the more fundamental reality that is produced by the macroevolutionary process, and it could include every level of gradation of genetic and morphological divergence. Once ranks are imposed upon it, a variety of methodological problems are created as scientists attempt to make these ranks standardized and comparable across different datasets and timescales. I outline how phylogenetic thinking might help provide a solution. I conclude with other examples where cutting-edge science is done with phylogenies without much need of the “species” rank—for example, in the battle against Covid-19.

Résumé :
AbstractUnlike traditional empiricism-based building design, the data-oriented quantitative analysis method is more rigorous and intuitive, taking into account a variety of factors such as site conditions, functional requirements and design specifications, and combining computer technology to propose a more rational and efficient design strategy. This study takes the design logic process and algorithm rule screening as the entry point to explore the design method of using multi-agent body algorithm planning to realize the spatial layout of university education buildings. Based on multi-agent algorithms, spatially rich and morphologically complex architectural solutions can be quickly generated, and new designs with generality and universality can be produced by changing the initial shape and syntax rules. The authors attempt to design a program based on a multi-agent body system, where architects only need to set initial parameters to quickly construct a variety of initial volume solutions, offering a wide range of possibilities for initial design.

Résumé :
Borders may be built for security reasons however; they also demarcate administrative, economic, socio-cultural, ethnic or religious divergence. Borders change the destinies of the societies at both sides because they affect the process of urban development and delimit the economic and socio-cultural interactions. Cyprus has been experiencing an interrupted continuity along the border, i.e. green line, under the rule of UN that divides north from the south. In this regard the aim of the study is to figure out how the de facto borders affect the configuration of villages upon their existing position. As a part of an ongoing research which investigates all eleven frontier villages and towns located along the border line, this paper only focuses on the morphological and syntactic comparison of four frontier villages. Within this context, initial exploration is about the village morphologies by means of Morphological Regions based on the evolutionary insights of Conzen (2004) and Whitehand (2009). Additionally, considering shifted centrality and transformed social gathering spaces, research discusses the applicability of the comparative analyses of syntactic and morphological methods in order to reveal the characteristics of the frontier villages. The preliminary findings of the research indicates that edge villages located along the green line have a controlled spatial development with dead ends and loop layouts, where the spatial configuration presents an introverted structure. On the other hand, villages divided by the green line, presents a relatively integrated spatial structure developed on both sides of the border, maintaining traditional centrality along with emphasizing forced territoriality.

Résumé :
Abstract The recent development of the Enriched Analytical Solution Method (EASM) for evaluating the spatio-temporal distribution of the temperature fields generated during the Laser Powder Bed Fusion (LPBF) Additive Manufacturing (AM) processes is provides an opportunity to study the sensitivity of the morphological parameters characterizing the associated melt-pools as a function of process parameters. The present work exercises the EASM for the case of a single-path trace over a 316L base plate under LPBF heat deposition conditions. To assist in the evaluation of solidification parameters, the spatial derivatives of the EASM are also derived. A process parameter subspace spanned by the scan velocity and the laser power is considered and the EASM is utilized for deriving a number of geometrical morphological characteristics of the melt pool as well as the quantities controlling the evolution of the solidification front. Finally, comparisons with initial experimental results obtained by in-situ high speed synchrotron X-ray imaging, capturing the spatio-temporal evolution of the melt pool profile are also presented.

Résumé :
Society creates architectural styles and neighborhood types to communicate and promote values. Geographers and architects accordingly classify neighborhoods by historical periods, urban design, planning paradigms and plan elements, density, building types and architectural detail. This paper juxtaposes typo-morphological (historical emergence of urban forms through urban elements and pattern typologies) and spatial analytic (city defined by urban form factors and formulas) approaches in urban morphology to assess what explains neighborhood type statistically. The analyses of variance show that many urban form factors (residential and employment density, mix of residences and jobs, Floor Space Indexes (FSI), location, income, etc.) are statistically significant in neighborhood type (as a nominal composite variable). This means that neighborhood typologies be applied in spatial analyses and urban modelling as classes (context variables). The approach can be used in typo-morphological tradition to offer quantitative description to the persistent ‘problem of type’ and enrich the classification methodology.

Résumé :
Several mitigation and adaptation strategies are proposed to tackle the environmental issues associated to massive urbanization and climate change. All these solutions are highly related to the utilization of urban surfaces (i.e. building envelopes, streets, public spaces, etc.). However, the existing trends demonstrate the lack of a systemic approach able to integrate multiple possible functions and avoid sub-optimal solutions. In this context, urban planning can play an essential role in managing conflicts among different surface uses and ensuring their integration. This involves making spatially explicit decisions about the types of surface use allowable, and their extent and location. The decision-making process needs to be supported by accurate and detailed knowledge about the spatial distribution of a variety of parameters that influence the surface uses in cities. This study presents a systematic framework to support planning decisions based on accurate, diverse and spatially explicit information, and discusses its application in a residential district located in Bolzano (Italy). The proposed method implies the assembly of a multivariate spatial database of significant morphological and environmental parameters acquired through environmental simulation techniques and on-site data collection. The three-dimensional visualization of this database represents a solid base to relate urban planning decisions on surface uses to their effects in terms of microclimatic conditions, thermal comfort, and on-site renewable energy production.

Résumé :
A Study of Chinese Traditional Wetland Island Settlement Combining Morphological and Narrative Analyses Dongxue Lei¹, Andong Lu² School of Architecture and Urban Planning, Nanjing UniversityHankou Road 22#, Gulou District, Nanjing, ChinaE-mail: dxlei@outlook.com, andonglu@gmail.com Keywords (3-5): wetland island settlement, morphology, townscape, cognitive map Conference topics and scale: Tools of analysis in urban morphology The Lixiahe region, a low-lying wetland located to the eastern side of the Huaiyang section of the Grand Canal, is characterized by a complex hydrological environment and has changed slowly in the urbanization process. The historical town of Shagou, a representative case of island settlements in this region, has a recorded history of continuous morphological change over six hundred years. Regarding Shagou as a cultural-geographical entity, this article aims at combining morphological analysis and narrative-based cognitive mapping to revel the characteristic townscape that strongly depends on cultural-geographic complexity. Based on survey work, this article will first define distinguishable plan elements that underpins the spatial form of Shagou: 1) natural context; 2) streets system; 3) plots system, and then investigate diachronically different phases of the formation of its spatial structure. On the other hand, based on archiving and data analysis of the oral history study, this article will generate a narrative cognitive map, in terms of paths, nodes, landmarks and areas. In conjunction with fieldwork and documentary record, this study testifies that the method derived from the plan analysis developed by Conzon is applicable to the study of wetland island settlement form in China and that narrative spatial analysis provides important supplemental spatial information. A careful combination of these methods might be used for understanding culturally embedded settlement forms in China. References (100 words) Conzen, M. R. G.

Résumé :
This paper presents the results of an experimental study comparing cortical activation in the brain when generating solutions using brainstorming, morphological analysis, and TRIZ. Twelve engineering students were given the same three design tasks, respectively, using the three solution generation techniques. Students generated solutions while change in oxygenated blood along the prefrontal cortex (PFC) was measured using functional near-infrared spectroscopy. The results show that generating solutions using brainstorming, morphological analysis, and TRIZ leads to differences in cortical activation, specifically along the region of the brain associated with spatial working memory, cognitive flexibility, and abstract reasoning, called the left dorsolateral prefrontal cortex (left DLPFC). Brainstorming evokes a high average blood oxygenation level dependent (BOLD) response in the left DLPFC early during the solution generation process but this high response is not sustained. In comparison, morphological analysis and TRIZ evoke multiple high average BOLD responses across the solution generation process. Not only was the high average BOLD response sustained but the density of network coordination among brain regions across the PFC was greater for morphological analysis and TRIZ. Higher density is a proxy for higher cognitive effort. The brain regions most central to coordination also varied. During brainstorming the right hemisphere, in a region associated with memory encoding (right PFC), was most activated. During morphological analysis, the left hemisphere, the left DLPFC was most activated. During TRIZ, both the middle and left hemisphere included regions of high activation. These results indicate neuro-cognitive differences of activation patterns, cognitive effort over time, and brain regions central for coordination when using these three concept generation techniques. Future research can begin to explore neuro-cognitive differences as a result of these techniques over multiple uses and the effects of design education.

Résumé :
This report documents the geomorphic assessment component of the Old River, Mississippi River, Atchafalaya River, and Red River System Technical Assessment. The overall objectives of the geomorphic assessment are to utilize all available data to document the historic trends in hydrology, sedimentation, and channel geometry for the rivers in the vicinity of the Old River Control Complex and to summarize the changes observed at locations where repetitive datasets exist and at key reaches that are determined during the study. The geomorphic assessment tasks include data compilation, geometric data analysis, gage and discharge analysis, dredge record analysis, sediment data analysis, development of an events timeline, and integration of results. Geomorphic reaches were developed, and the morphological trends during different time periods were identified. The geomorphic assessment highlighted the importance of considering spatial and temporal variability when assessing morphological trends.

Résumé :
A complete Rasch multi-faceted analysis was performed on the draft Spatial Reasoning Assessment. While the psychometric report presents the complete analysis for the examination, this discussion proceeds step-by-step to understand the way in which the analysis proceeded, and the findings therein. The findings were that holistically, the instrument performed admirably. As a pretest, it is likely that students were not expected to demonstrate certain reasoning skills (e.g., GIS) as indeed they did not. The rating scale functions well to capture the examiner judgement. Overall, the instrument works together as a functional assessment, capturing the general construct of Spatial Reasoning.
