Book excerpt: [résumé en français]Cette thèse est dédiée à la gestion des objets complexes, persistants et évolutifs propres aux nouvelles applications des bases de données. Nous nous intéressons plus spécialement aux bases de données pour les environnements du génie logiciel. Notre contribution concerne la modélisation de ces objets et l'évolution ainsi que intégration des schémas des bases de donnnées qui les contiennent. Nous proposons également, des mécanismes permettant l'adaptation de ces bases de données (données et programmes) aux différents types d'évolution. Nous avons d'abord défini un modèle de données générique à typage fort et englobant les concepts communément admis dans les modèles sémantiques et le paradigme objet (agrégation, groupement, héritage etc.). Ce modèle est formalisé par des types abstraits graphes. Une étude systématique de ces types abstraits nous a permis de définir un ensemble de modifications élémentaires de schémas qui sont elles-mêmes formalisées comme des opérations associées aux types graphes. Cette approche nous a permis de définir de façon rigoureuse, la gestion des impacts des modifications de schémas.Un processus d'intégration de schémas d'objets complexes a également été proposé, il se caractérise par sa phase de comparaison de schémas qui s'effectue à l'aide d'un raisonnement hypothétique. Du point de vue de la gesiton de l'impact de l'évolution de schémas sur les bases de données existantes, nous proposons un mécanismes permettant l'adaptation des instances et de sprogrammes ainsi qu"une gestion de versions de schémas. Ce mécanisme se base sur la définition, dans certains cas automatique, de fonctions de correspondance formalisées par des homorphismes. Ces fonctions peuvent en effet, être utilisées pour réaliser la conversion des instances ou pour implanter un polymorphisme ad hoc avec crcion de types. Les propositions de cette thèse ont fait l'objet d'une implantation sur une plate-forme orientée objet (smalltalk object-works)

This book was released on 2019-02-28 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Open Access book presents feedback from the ‘Territorial Agroecological Transition in Action’- TATA-BOX research project, which was devoted to these specific issues. The multidisciplinary and multi-organisation research team steered a four-year action-research process in two territories of France. It also presents: i) the key dimensions to be considered when dealing with agroecological transition: diversity of agriculture models, management of uncertainties, polycentric governance, autonomies, and role of actors’ networks; ii) an operational and original participatory process and associated boundary tools to support local stakeholders in shifting from a shared diagnosis to a shared action plan for transition, and in so doing developing mutual understanding and involvement; iii) an analysis of the main effects of the methodology on research organisation and on stakeholders’ development and application; iv) critical analysis and foresights on the main outcomes of TATA-BOX, provided by external researchers.

Download or read book Persistence Theory From Quiver Representations to Data Analysis written by Steve Y. Oudot and published by American Mathematical Soc.. This book was released on 2017-05-17 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Persistence theory emerged in the early 2000s as a new theory in the area of applied and computational topology. This book provides a broad and modern view of the subject, including its algebraic, topological, and algorithmic aspects. It also elaborates on applications in data analysis. The level of detail of the exposition has been set so as to keep a survey style, while providing sufficient insights into the proofs so the reader can understand the mechanisms at work. The book is organized into three parts. The first part is dedicated to the foundations of persistence and emphasizes its connection to quiver representation theory. The second part focuses on its connection to applications through a few selected topics. The third part provides perspectives for both the theory and its applications. The book can be used as a text for a course on applied topology or data analysis.

Download or read book Veracity of Data written by Laure Berti-Équille and published by Morgan & Claypool Publishers. This book was released on 2015-12-01 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Web, a massive amount of user-generated contents are available through various channels (e.g., texts, tweets, Web tables, databases, multimedia-sharing platforms, etc.). Conflicting information, rumors, erroneous and fake contents can be easily spread across multiple sources, making it hard to distinguish between what is true and what is not. This monograph gives an overview of fundamental issues and recent contributions for ascertaining the veracity of data in the era of Big Data. The text is organized into six chapters, focusing on structured data extracted from texts. Chapter One introduces the problem of ascertaining the veracity of data in a multi-source and evolving context. Issues related to information extraction are presented in chapter Two. It is followed by practical techniques for evaluating data source reputation and authoritativeness in Chapter Three, including a review of the main models and Bayesian approaches of trust management. Current truth discovery computation algorithms are presented in details in Chapter Four. The theoretical foundations and various approaches for modeling diffusion phenomenon of misinformation spreading in networked systems is studied in Chapter Five. Finally, truth discovery computation from extracted data in a dynamic context of misinformation propagation raises interesting challenges that are explored in Chapter Six. Supplementary material including source codes, datasets, and slides are offered online. This text is intended for a seminar course at the graduate level. It is also to serve as a useful resource for researchers and practitioners who are interested in the study of fact-checking, truth discovery or rumor spreading.
Download or read book Facilitating Sustainable Agriculture written by N. G. Roling and published by Cambridge University Press. This book was released on 2000-09-21 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: A move towards more flexible, sustainable agricultural practices is increasingly being seen as the way to address or avoid environmental and economic problems associated with existing, predominantly intensive, farming systems. Through case studies taken from around the world, this book examines the implications of adopting more ecologically sound agricultural practices, both at the level of individual farmers and at the level of larger-scale agro-ecosystems such as water catchments. The emphasis of the book is on human and social aspects, rather than on agronomic or economic considerations, focusing on the learning processes necessary for change to be implemented and, in turn, on the facilitation of that learning through participatory approaches and appropriate institutional support and policy structure.

Download or read book System Architecture and Complexity written by Jacques Printz and published by John Wiley & Sons. This book was released on 2020-07-16 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emergence of a true systemic science - the systemic one - capable of rigorously addressing the many problems posed by the design and management of the evolution of modern complex systems is therefore urgently needed if wants to be able to provide satisfactory answers to the many profoundly systemic challenges that humanity will have to face at the dawn of the third millennium. This emergence is of course not easy because one can easily understand that the development of the systemic is mechanically confronted with all the classical disciplines which can all pretend to bring part of the explanations necessary to the understanding of a system and which do not naturally see a good eye a new discipline claim to encompass them in a holistic approach ... The book of Jacques Printz is therefore an extremely important contribution to this new emerging scientific and technical discipline: it is indeed first of all one of the very few "serious" works published in French and offering a good introduction to the systemic. It gives an extremely broad vision of this field, taking a thread given by the architecture of systems, in other words by the part of the systemic that is interested in the structure of systems and their design processes, which allows everyone to fully understand the issues and issues of the systemic. We can only encourage the reader to draw all the quintessence of the masterful work of Jacques Printz which mixes historical reminders explaining how the systemic emerged, introduction to key concepts of the systemic and practical examples to understand the nature and the scope of the ideas introduced.
Download or read book Classical Architecture written by Alexander Tzonis and published by MIT Press. This book was released on 1986-10-16 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fascinating introduction to classical art and architecture is the first book to investigate the way classical buildings are put together as formal structures. It researches the generative rules, the poetics of composition that classical architecture shares with classical music, poetry, and drama, and is enriched by a variety of examples and an extensive analysis of compositional rules. The 205 line drawings make up a discourse of their own, a pictorial text that serves as an introductory theory of composition or basic design aid. Drawing from Vitruvius, the poetics of Aristotle, the theories of classical architecture, music, and poetry since the Renaissance, and the poetics of the Russian formalists, the authors present classical architecture as a coherent system of architectural thinking that is capable of producing a tragic humanistic discourse, a public art with critical, moral, and philosophical meaning.
