Book Description
Le présent travail concerne le développement d'une méthode d'éco-conception pour la création de produits impliquant des indicateurs environnementaux pour l'aide à la prise de décision au stade de la conception conceptuelle. La méthode proposée s'appuie sur la définition et la génération d'un TRIPLET, c'est-à-dire une relation cohérente entre matériaux, procédés et formes. Une taxonomie de formes caractérise les différentes formes réalisables par les procédés de fabrication. Un tableau de description du concept (DCT) regroupe certaines dimensions globales de la pièce imaginée ainsi que les procédés d'enlèvement de matière de finition venant s'additionner au procédé de base sélectionné. Un indicateur environnemental basé sur la base RECIPE et adapté à la méthode peut être alors évalué. La démarche d'aide à la conception conçue intègre deux approches, déductive et inductive basées sur l'expérience du concepteur. Le DCT comprend le choix d'un solide de base qui suggère, à partir des surfaces fonctionnelles définies dans la démarche, une réflexion vers une esquisse du concept de pièce. Les différents concepts élaborés sont hiérarchisés à partir d'une aide à la décision multicritère basée sur l'indicateur environnemental, sur un coût de fabrication, sur un indice de performance et sur un indice de combinaison obtenu par logique floue. La démarche s'appuie sur une base de données lié aux connaissances requises et sur un outil logiciel « ECOTRIAL ». Une application de reconception d'une pièce de liaison clôt la thèse et montre l'applicabilité de la méthode proposée.

Book Description
Life Cycle Assessment (LCA) has developed in Australia over the last 20 years into a technique for systematically identifying the resource flows and environmental impacts associated with the provision of products and services. Interest in LCA has accelerated alongside growing demand to assess and reduce greenhouse gas emissions across different manufacturing and service sectors. Life Cycle Assessment focuses on the reflective practice of LCA, and provides critical insight into the technique and how it can be used as a problem-solving tool. It describes the distinctive strengths and limitations of LCA, with an emphasis on practice in Australia, as well as the application of LCA in waste management, the built environment, water and agriculture. Supported by examples and case studies, each chapter investigates contemporary challenges for environmental assessment and performance improvement in these key sectors. LCA methodologies are compared to the emerging climate change mitigation policy and practice techniques, and the uptake of ‘quick’ LCA and management tools are considered in the light of current and changing environmental agendas. The authors also debate the future prospects for LCA technique and applications.

Book Description
This important and insightful book provides, for the first time, a broad presentation of ongoing research into public participation in landscape conservation, management and planning, following the 2000 European Landscape Convention which came into force in 2004. The book examines both the theory of participation and what lessons can be learnt from specific European examples. It explores in what manner and to what extent the provisions for participation in the European Landscape Convention have been followed up and implemented. It also presents and compares different experiences of participation in selected countries from northern, southern, eastern and western Europe, and provides a critical examination of public participation in practice. However, while the book’s focus is necessarily on Europe, many of the conclusions drawn are of global relevance. The book provides a valuable reference for researchers and advanced students in landscape policies and management, as well as for professionals and others interested in land-use planning and environmental management.

Book Description
It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

Book Description
This book presents topics on the basics of materials selection and design which will give a better understanding on the selection methods and then find suitable materials for the applications. This book draws the simple and straightforward quantitative methods followed by knowledge-based expert system approach with real and tangible case studies to show how undergraduate or post-graduate students or engineers can apply their knowledge on materials selection and design. Topics discussed in this book contain special features such as illustration, tables and tutorial questions for easy understanding. A few published books or documents are available, hence this book will be very useful for those who use (or want to use) materials selection approach without the advantages of having had comprehensive knowledge or expertise in this materials’ world.

Book Description
The first book in inference for stochastic processes from a statistical, rather than a probabilistic, perspective. It provides a systematic exposition of theoretical results from over ten years of mathematical literature and presents, for the first time in book form, many new techniques and approaches.

Book Description
This book summarizes current knowledge regarding the theory of estimation for semiparametric models with missing data, in an organized and comprehensive manner. It starts with the study of semiparametric methods when there are no missing data. The description of the theory of estimation for semiparametric models is both rigorous and intuitive, relying on geometric ideas to reinforce the intuition and understanding of the theory. These methods are then applied to problems with missing, censored, and coarsened data with the goal of deriving estimators that are as robust and efficient as possible.
