Book excerpt: DANS LE CONTEXTE DE MARCHES DE PLUS EN PLUS CONCURRENTIELS, LES ENTREPRISES MANUFACTURIERES SE DOIVENT DE PROPOSER DES GAMMES DE PRODUITS LES PLUS VASTES POSSIBLES AFIN DE RESTER COMPETITIVES. L'APPROCHE METHODOLOGIQUE PROPOSE VISE A ELABORER UNE DEMARCHE DE CONCEPTION DES SYSTEMES D'ASSEMBLAGE DEDIEE A CES ENSEMBLES DE PRODUITS. UNE PREMIERE PARTIE DEFINIT LA NOTION DE FAMILLE DE PRODUITS BASEE SUR LES FONCTIONS QU'ILS ASSURENT ET PRESENTE UNE METHODE D'ANALYSE DE CES FAMILLES. DANS UN PREMIER TEMPS, L'UTILISATION DES CONCEPTS DE DESCRIPTEUR ET D'ATTRIBUT PERMET DE CARACTERISER LES DIFFERENTS PRODUITS D'UNE FAMILLE ET DE CONSTITUER DES SOUS-FAMILLES. LES ELEMENTS DE DESCRIPTION (INTERFACE INTERNE, INTERFACE EXTERNE, SIGNATURE) ET LE ROLE FONCTIONNEL DES COMPOSANTS DANS LEURS PRODUITS RESPECTIFS CONSTITUENT LA BASE DE LEUR COMPARAISON. CETTE DEUXIEME ETAPE DE L'ANALYSE CONDUIT A LA CREATION DE CLASSES DE CORRESPONDANCE DE COMPOSANTS. L'ELABORATION D'UN MODELE COMMUN A L'ENSEMBLE DES PRODUITS DE LA FAMILLE EST PRESENTEE DANS UNE SECONDE PARTIE. LE GRAPHE GENERIQUE ETIQUETE REPOSE SUR LA DOUBLE CORRESPONDANCE SOMMET/COMPOSANT ELEMENTAIRE ET ARETE/LIAISON FONCTIONNELLE ET ASSOCIE A CHAQUE SOMMET ET ARETE UNE ETIQUETTE PRECISANT LES PRODUITS AUXQUELS APPARTIENT LE COMPOSANT OU LA LIAISON FONCTIONNELLE CORRESPONDANT. L'EXPLOITATION DE CE MODELE CONDUIT A LA GENERATION DES GAMMES D'ASSEMBLAGES DEDIEES A LA FAMILLE. UNE MATRICE ASSOCIEE A CHAQUE GAMME TRADUIT L'ADMISSIBILITE DES OPERATIONS QUI LA COMPOSENT POUR LES DIFFERENTS PRODUITS DE LA FAMILLE. DIFFERENTES STRATEGIES D'ASSEMBLAGE DE FAMILLES DE PRODUITS SONT ETUDIEES DANS UNE TROISIEME PARTIE. LES GAMMES A VARIABILITE MINIMALE CONSTITUENT DES REPONSES INTERESSANTES A LA FLEXIBILITE REQUISE POUR L'ASSEMBLAGE DE PRODUITS DIFFERENTS. LA SELECTION DES GAMMES MET EN UVRE DES CRITERES PROPRES A CHAQUE PRODUIT ET DES CRITERES LIES A LA FAMILLE. LES TAUX DE VARIATION CALCULES POUR CHAQUE OPERATION DEFINISSENT LA COMPLEXITE DYNAMIQUE D'UNE GAMME PAR RAPPORT A L'ORDONNANCEMENT DES PRODUITS DE LA FAMILLE SUR LE SYSTEME D'ASSEMBLAGE

This book was released on 2013-11-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

Download or read book Terra 2008 written by Leslie Rainer and published by Getty Publications. This book was released on 2011-06-14 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

That the terms "fish" and "invertebrates" do not indicate scientific groupings? All this is the result of major changes in classification. This book diagrams the tree of life according to the most recent methods of this system.

Download or read book Biomimicry written by Janine M. Benyus and published by Harper Collins. This book was released on 2009-08-11 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Repackaged with a new afterword, this "valuable and entertaining" (New York Times Book Review) book explores how scientists are adapting nature's best ideas to solve tough 21st century problems. Biomimicry is rapidly transforming life on earth. Biomimics study nature's most successful ideas over the past 3.5 million years, and adapt them for human use. The results are revolutionizing how materials are invented and how we compute, heal ourselves, repair the environment, and feed the world. Janine Benyus takes readers into the lab and in the field with maverick thinkers as they: discover miracle drugs by watching what chimps eat when they're sick; learn how to create by watching spiders weave fibers; harness energy by examining how a leaf converts sunlight into fuel in trillionths of a second; and many more examples. Composed of stories of vision and invention, personalities and pipe dreams, Biomimicry is must reading for anyone interested in the shape of our future.

Download or read book Product Life Cycle Management written by Max Giordano and published by John Wiley & Sons. This book was released on 2012-12-17 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a comprehensive view of the most recent major international research in the field of tolerancing, and is an excellent resource for anyone interested in Computer Aided Tolerating. It is organized into 4 parts. Part 1 focuses on the more general problems of tolerance analysis and synthesis, for tolerancing in mechanical design and manufacturing processes. Part 2 specifically highlights the simulation of assembly with defects, and the influence of tolerances on the quality of the assembly. Part 3 deals with measurement aspects, and quality control throughout the life cycle. Different measurement technologies and methods for estimating uncertainty are considered. In Part 4, different aspects of tolerancing and their interactions are explored, from the definition of functional requirement to measurement processes in a PLM approach.

This book was released on 2019-02-28 with total page 335 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 Numerical Methods for Partial Differential Equations written by Sandip Mazumder and published by Academic Press. This book was released on 2015-12-01 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical Methods for Partial Differential Equations: Finite Difference and Finite Volume Methods focuses on two popular deterministic methods for solving partial differential equations (PDEs), namely finite difference and finite volume methods. The solution of PDEs can be very challenging, depending on the type of equation, the number of independent variables, the boundary, and initial conditions, and other factors. These two methods have been traditionally used to solve problems involving fluid flow. For practical reasons, the finite element method, used more often for solving problems in solid mechanics, and covered extensively in various other texts, has been excluded. The book is intended for beginning graduate students and early career professionals, although advanced undergraduate students may find it equally useful. The material is meant to serve as a prerequisite for students who might go on to take additional courses in computational mechanics, computational fluid dynamics, or computational electromagnetics. The notations, language, and technical jargon used in the book can be easily understood by scientists and engineers who may not have had graduate-level applied mathematics or computer science courses. Presents one of the few available resources that comprehensively describes and demonstrates the finite volume method for unstructured mesh used frequently by practicing code developers in industry Includes step-by-step algorithms and code snippets in each chapter that enables the reader to make the transition from equations on the page to working codes Includes 51 worked out examples that comprehensively demonstrate important mathematical steps, algorithms, and coding practices required to numerically solve PDEs, as well as how to interpret the results from both physical and mathematic perspectives

Download or read book On the Take written by Lindy Muzila and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite broad international recognition of the criminalization of illicit enrichment, it has not been universally accepted as an anti-corruption measure. Instead, criminalization of illicit enrichment continues to generate extensive debate and controversy. Against this background, this volume aims to provide an analysis of how illicit enrichment works, and attempts to shed light on any contributions that it has made to the fight against corruption and the recovery of stolen assets. Rather than delving into the theoretical and academic debates around illicit enrichment, this study focuses primarily on the analysis of current practice, case law, and existing literature to offer a new perspective to the on-going discussions. More specifically, the volume addresses the legal framework upon which the concept of illicit enrichment rests, and the resulting policy implications of that legal framework. It also focuses on illicit enrichment as an anti-corruption mechanism, from its roots as a response to the problems inherent to prosecutions involving corruption, to an examination of elements and inchoate offenses relating to illicit enrichment under international conventions. It examines illicit enrichment jurisprudence in the global context. An extensive survey was carried out to determine the countries where the offense exists, what form it takes, how often it is used, and for countries where it doesn't, what other measures are used in its place. The authors neither recommend nor oppose the adoption of illicit enrichment provisions, but rather aim to assist jurisdictions considering such steps by highlighting key questions that might arise during implementation, including how the offense is defined and enforced domestically by States. Similarly, the authors do not endorse nor criticize any practice carried out by States in the implementation of the criminalization of illicit enrichment. Ultimately, it is also hoped that this study provides a basis for further discussion amongst policy makers and practitioners, and fuels upcoming discussions by the Conference of State parties of the UNCAC and its Working Groups
