Uma ferramenta de monitoração para um núcleo de resolução distribuída de problemas orientado a objetos. / A monitoring fool for an object oriented distributed problem solving kernelr .

Sichman, Jaime Simão 19 June 1991 (has links)
Este trabalho consiste no projeto e implementação de uma ferramenta de monitoração para um núcleo de resolução distribuída de problemas denominado dpsk+p. Tal núcleo permite que diversos agentes, desenvolvidos em diferentes linguagens que suportam o paradigma de objetos, compartilhem dados e métodos entre si, de modo a cooperarem no processo de resolução de determinado problema. A ferramenta de monitoração é baseada em eventos de comunicação e controle entre agentes, utilizando a técnica de animação de processos para efeito de exibição dos resultados. Além disso, propõe um método eficiente de exibição do fluxo de comunicação em sistemas baseados em memória compartilhada, aproveitando a compacidade presente nas hierarquias de classes que compõem um sistema orientado a objetos.PCS. / This work consists of the design and implementation of a monitoring facility for an object-oriented distributed problem solving kernel named DPSK+P. This kernel allows both data and method sharing between agents, that may have been developed in different object-oriented programming languages, so that they can cooperate in a problem solving activity. The monitoring facility is based on control and communication events, and its exhibition of results uses process animation techniques. It also presents an efficient framework for the exhibition of the communication flow in shared memory based systems, which profiles the existing compactness in object-oriented class hierarchies.

Télédétection et atlas de paysages : approche multiscalaire des paysages en Bretagne / Remote sensing and landscape Atlas : a multiscalar approach of landscapes in Brittany

Bourget, Emilie 13 December 2011 (has links)
A l’échelle de la Bretagne comme de la France, la gestion et la protection des paysages passe en premier lieu par leur connaissance, ainsi que le stipule la Convention Européenne du Paysage (2000). La présente recherche propose une approche objectivée du paysage, considéré comme une partie visible du territoire, dont les caractères peuvent s’étudier àdifférentes échelles. Un état de l’art de la définition et de la cartographie des unités paysagères permet tout d’abord de passer en revue les différentes approches, scientifiques et plus usuelles, de la délimitation des paysages, et conduit à proposer une méthode alliant traitements d’une classification pixel à moyenne résolution spatiale et connaissances expertes, afin de produire un découpage harmonisé des ensembles paysagers à l’échelle régionale. Une seconde méthodologie basée sur le traitement « orienté-objet » de données télédétectées à haute résolution spatiale aboutit ensuite à la définition des unités paysagères à l’échelle infradépartementale sur deux zones d’étude (le Pays de Saint-Brieuc et l’ensemble paysager des Landes de Lanvaux), et à l’approche renouvelée du traitement des limites de ces unités :l’utilisation de buffers permet d'établir une typologie quantitative de ces limites, du passage franc au continuum paysager. Enfin, l’analyse paysagère et les cartographies produites dans les deux premières parties de la réflexion sont appliquées, dans une optique écopaysagère, à la problématique actuelle de délimitation des Trames Vertes et Bleues impulsée par le Grenelle de l’Environnement ; elles peuvent constituer un socle de réflexion dans la caractérisation des réseaux écologiques par l’approche « habitat », mais également permettre spécifiquement une délimitation plus fine des paysages de vallées, dans une optique d’aide à la décision dans ces politiques publiques / At the level of France or of Brittany, landscapes management and protection cannot be undertaken without an identification of landscape units, as noted in the European Landscape Convention (2000). The present research proposes a descriptive approach of landscape, as an area visible on a territory, which characters can be studied on several scales. A state of art ofthe definition and the cartography of landscape units allows reviewing the different approaches, scientific or more usual, of landscapes delimitation, and then leads to propose a method which combines some automatic processing of a medium spatial resolution, per-pixel classification, with expert-knowledge, in order to produce a harmonized delimitation oflandscape sets at regional scale. A second methodology based on the “object-oriented” processing of high-resolution remote sensed data leads to the definition of landscape units at infradepartmental scale, on two different study areas (the Pays de Saint-Brieuc and the landscape group of Lanvaux moorland, in Brittany). It also leads to the renewed approach ofthe analysis of landscape unis boundaries: using buffers provide a quantitative typology of these boundaries, from straight crossing to landscape continuum. Finally, landscape analysis and cartographies produce in the first two parts of the research are applied to the actual question of greenways and blueways delimitation, in order to set up an eco-landscapeapproach; they can frame a first step in the characterization of ecological networks with the habitat approach, but also allows a finer delimitation of landscape valleys, in order to contribute to public policies

全球化製造資訊系統之架構與分析方法的研究 / The Research on Developing an Architecture and a System Analysis Approach for Global Manufacturing Information System

許祐嘉, Hsu, Yow-Jia Unknown Date (has links)
隨著全球化生產型態的轉變以及區域製造中心的形成,傳統位於單一地點的製造環境早已不符合企業實際的需求,取而代之的是一個全球化的製造環境。而由於全球化的環境容易造成溝通與協調上的不便,因此如何利用資訊科技發展出一個完善的資訊系統來支援製造功能,乃是一件刻不容緩的事情。本研究首先探討全球化製造環境的特性,並依據此特性提出一個符合此環境需求之製造資訊系統的架構,再就此架構建立出一簡單的概念模型。最後,並提出一個以物件導向方法為基礎的系統分析方法,來協助企業管理人員發展出符合其企業特質之製造資訊系統。 / Due to the change of production type and the development of regional manufacturing centers, the traditional and stand-alone manufacturing environment is no longer suitable to the operations of modern manufacturing enterprise. Instead of it, a global manufacturing environment is to be paid much attention to recently. Since the global environment is easy to make the communication and coordination be inconvenient, how to apply information technology to develop a well-defined information system for supporting manufacturing functions of the enterprise is an important task to be accomplished.In this research, firstly, we try to clarify the properties of a global manufacturing environment, then propose an architecture for the manufacturing information system based on these properties. Secondly, we intend to establish a model of the global manufacturing information system based on the architecture that we proposed. Finally, we will develop an object-oriented analysis approach to help the system analysts to build a manufacturing information system for their own-purpose and own-characteristics.

Compréhension et modélisation des processus hydrologique dans un petit bassin versant périurbain à l'aide d'une approche spatialisée orientée objet et modulaire. Application aux sous-basins de la chaudanne et du mercier (bassin de l'Yzeron, France) / Understanding and modelling of hydrological processes in small peri-urban catchments using an object-oriented and modular distributed approach. Application to the Chaudanne and Mercier sub-catchments (Yzeron catchment, France).

Jankowfsky, Sonja 15 December 2011 (has links)
La densification actuelle de l'urbanisation conduit à un changement d'occupation du sol et du réseau de drainage en zone péri-urbaine. L'écoulement est concentré dans des fossés ou des réseaux d'assainissement et ainsi accéléré. Ces phénomènes peuvent avoir des conséquences importantes pour les nappes et les cours d'eau, comme par exemple l'aggravation des crues et des sécheresses et l'altération de la qualité chimique et/ou biologique du milieu. Sous la pression réglementaire (Directive Cadre Européenne sur l'Eau) et la demande sociale, les gestionnaires sont donc confrontés à des choix complexes en terme d'aménagement. Ainsi, il est nécessaire de mettre au point des méthodes et des modèles capables de quantifier l'impact de l'augmentation de l'urbanisation sur la vulnérabilité des hydro-systèmes péri-urbains. Dans ce travail, nous formulons l'hypothèse qu'une modélisation hydrologique spatialisée continue, prenant explicitement en compte les objets des paysages périurbains (parcelles urbaines, agricoles, forestières, haies,..) et les éléments déterminant les chemins de l'eau (topographie, mais aussi réseaux d'assainissement ou de routes) peut aider à comprendre et hiérarchiser le rôle des différents objets du paysage sur la réponse hydrologique. Pour ce faire, le modèle distribué PUMMA (Peri-Urban Model for landscape Management) adapté aux bassins versants péri-urbains, a été développé dans le cadre de cette thèse. Il consiste en une intégration du modèle existant URBS, décrivant des processus hydrologiques urbains à l'échelle d'une parcelle cadastrale, dans la plate-forme de modélisation LIQUID, qui contient déjà des modules représentants des processus hydrologiques en zone rurale. PUMMA a également été complété par de nouveaux modules simulant les déversoirs d'orage, les bassins de rétention et le transfert du ruissellement de surface. Le modèle suit une approche orientée objet dans laquelle le paysage est divisé en mailles irrégualières, correspondant aux parcelles cadastrales en zone urbaine et aux unités de réponse hydrologiques (HRUs) en zone rurale. Afin de pouvoir appliquer le modèle à l'échelle d'un bassin versant, des méthodes automatiques pour la préparation des données géographiques ont été mises au point. De plus, une méthode a été développée pour déterminer les contours de bassins versants péri-urbains, en distinguant les surfaces contributives de temps sec et humide. Le modèle a été appliqué au bassin versant de la Chaudanne, un sous-bassin de l'Yzeron, situé en zone péri-urbaine lyonnaise pour deux années en conditions contrastées (sèche et humide). Les paramètres du modèle ont été spécifiés à partir des observations disponibles et des données de la littérature. Les résultats montrent un comportement du modèle réaliste et une aptitude à représenter les comportements différents en période sèche et humide, en lien avec des degrés de saturation des sols différents, même si les pics de débits d'été sont en général surestimés. Différents tests de sensibilité sur certains processus/paramètres montrent l'importance des processus urbains sur la réponse hydrologique du bassin, comme en particulier la génération de ruissellement de surface par les surfaces imperméables et naturelles urbaines, le drainage de l'eau du sol par les réseaux d'assainissement et les connexions entre les îlots urbains et le réseau hydrographique naturel et artificiel. L'épaisseur des sols et la conductivité hydraulique à saturation latérale jouent aussi un rôle important sur la dynamique du débit de base. Nous montrons aussi le potentiel du modèle pour tester différents scenarii d'aménagement ou de gestion des eaux pluviales. / Urban expansion mainly affects peri-urban areas. These areas are subject to rapid modifications such as an increase of impervious areas or concentration of runoff in sewer systems. These changes have an impact on local hydrology and can induce floods, pollution or decrease of groundwater resource. Modelling tools allowing a quantification of the sensitivity of peri-urban catchments to urbanization are therefore useful in this context. The hypothesis underlying this PhD is that a continuous distributed hydrological model, taking explicitly into account the spatial organization of the landscape (urban, agricultural, forest areas, hedges,..) and the water pathways, as determined by topography but also roads and sewer networks, can help to understand and hierarchize the role of various landscape elements on the hydrological response of small hydrosystems. We therefore designed the Peri-Urban Model for landscape MAnagement (PUMMA) simulating the rainfall-runoff processes both in urban and in rural areas. For this, the urban model URBS was integrated into the LIQUID modelling framework already containing modules describing hydrological processes in rural areas. Additionally, three process modules were developed describing sewer overflow devices, overland flow as well as retention basins and lakes. PUMMA follows an object-oriented approach. The landscape is discretized into cadastral parcels in urban areas and irregular hydrological response units in rural areas. In order to apply PUMMA to the catchment scale, automatic methods were developed for the pre-processing of the geographical data. Furthermore, a method for the delineation of suburban catchments including the separation into dry and wet weather contributing areas was developed. The model was then applied to the Chaudanne catchment, a sub-basin of the Yzeron, located in the peri-urban area of Lyon, France. The model was run continuously for two contrasting years (dry and humid) using parameters values taken from observations and the literature. Although summer peak discharge is often overestimated, the results show that, the model is able to simulate realistically the observed discharges and in particular different responses under dry and wet conditions, controlled by the soil saturation. Sensitivity tests to various processes/parameters showed the importance of the urban influenced processes on the hydrological response, in particular surface runoff generation on impervious and natural urban surfaces, infiltration into the sewer system and the connexion of urban areas to the natural hydrographic network. Soil depth and lateral saturated hydraulic conductivity were also found influential on the base flow dynamics. We finally showed the model potential for the evaluation of various rain water management scenarios.
