Sedimentation and Sustainable Use of Reservoirs and River Systems / Sédimentation et Utilisation Durable des Réservoirs et Systèmes Fluviaux

Sedimentation and Sustainable Use of Reservoirs and River Systems / Sédimentation et Utilisation Durable des Réservoirs et Systèmes Fluviaux

ICOLD Bulletin 147 discusses the upstream and downstream fluvial morphological impacts of reservoir sedimentation and possible mitigation measures. The current state of and possible future sediment deposition in reservoirs have been investigated globally with the aid of the ICOLD Register on Dams. The global mean reservoir sedimentation rate was found to be 0. 8 % of the original storage capacity per year. The book also investigates the impacts of dams on the ecology related to fluvial morphological changes and guidelines are proposed to mitigate the impacts on the downstream river morphology. Finally an economical model is presented which considers a life cycle approach for reservoir conservation. Ce CIGB Bulletin 147 traite des impacts morphologiques fluviaux en amont et en aval de la sédimentation des réservoirs et des mesures d'atténuation possibles. L'état actuel et l'avenir possible du dépôt de sédiments dans les réservoirs ont été étudiés à l'échelle mondiale à l'aide du registre des barrages de la CIGB. Le taux moyen mondial de sédimentation des réservoirs s'est avéré être de 0 8 % de la capacité de stockage initiale par an. Le livre étudie également les impacts des barrages sur l'écologie liés aux changements morphologiques fluviaux et des directives sont proposées pour atténuer les impacts sur la morphologie des rivières en aval. Enfin un modèle économique est présenté qui prend en compte une approche de cycle de vie pour la conservation des réservoirs. | Sedimentation and Sustainable Use of Reservoirs and River Systems / Sédimentation et Utilisation Durable des Réservoirs et Systèmes Fluviaux

Tailings Dam Design / Conception des Barrages de Stériles Miniers Technology Update / Mise à Jour des Technologies

Tailings Dam Design / Conception des Barrages de Stériles Miniers Technology Update / Mise à Jour des Technologies

Tailings are produced from the processing of mineral ores and are commonly stored within embankment dams. The design of the dams requires application of sound engineering principles and an understanding of the properties of the tailings. This Bulletin provides a framework for classifying different types of tailings ranging from ultra-fine to coarse based on their geotechnical properties and provides typical geotechnical parameters for the different tailings types. Technologies for dewatering tailings to reduce the risk of storage continue to be developed and the different technologies from thickening to filtration and re-application of old technologies are presented to illustrate the options available and where appropriate typical in situ properties. This bulletin is directed towards a wide audience of stakeholders: designers owners regulators communities and various organizations and provides a reference for communicating tailings properties and the benefits and limitations of technologies. All mining operations and thereby tailings operations are unique. There is no one-solution-fits-all. Tailings dam designs need to account for site-specific conditions such as climate physiography geochemistry geomorphology seismology mining processes environment and community setting with the application of technologies playing an important role in developing safe sustainable tailings facilities. Les stériles miniers sont produits à partir du traitement des minerais et sont généralement stockés derrière des barrages en remblai. La conception des barrages nécessite l'application de principes d'ingénierie solides et une compréhension des propriétés des résidus. Ce bulletin fournit un cadre pour classer différents types de résidus allant de l'ultra-fin au grossier en fonction de leurs propriétés géotechniques et propose des paramètres géotechniques typiques pour les différentes sortes de résidus. Les technologies d'assèchement des résidus pour réduire le risque de stockage continuent à être développées ; les différentes technologies de l'épaississement à la filtration en passant par l’application des anciennes technologies sont présentées pour illustrer les options disponibles et le cas échéant les propriétés in situ typiques. Ce bulletin s'adresse à un large public d'intervenants : concepteurs propriétaires régulateurs communautés et organisations diverses et fournit une référence pour communiquer les propriétés des résidus et les avantages et les limites des technologies. Toutes les opérations minières et par conséquent les traitements des résidus sont uniques. Il n'y a pas de solution unique pour tous. La conception des barrages de résidus doit tenir compte des conditions propres au site telles que le climat la physiographie la géochimie la géomorphologie la sismologie les processus miniers l'environnement et le milieu communautaire l'application de technologies jouant un rôle important dans le développement de parcs à résidus sûrs et durables. | Tailings Dam Design / Conception des Barrages de Stériles Miniers Technology Update / Mise à Jour des Technologies

VLSI Architectures for Modern Error-Correcting Codes

VLSI Architectures for Modern Error-Correcting Codes

Error-correcting codes are ubiquitous. They are adopted in almost every modern digital communication and storage system such as wireless communications optical communications Flash memories computer hard drives sensor networks and deep-space probing. New-generation and emerging applications demand codes with better error-correcting capability. On the other hand the design and implementation of those high-gain error-correcting codes pose many challenges. They usually involve complex mathematical computations and mapping them directly to hardware often leads to very high complexity. VLSI Architectures for Modern Error-Correcting Codes serves as a bridge connecting advancements in coding theory to practical hardware implementations. Instead of focusing on circuit-level design techniques the book highlights integrated algorithmic and architectural transformations that lead to great improvements on throughput silicon area requirement and/or power consumption in the hardware implementation. The goal of this book is to provide a comprehensive and systematic review of available techniques and architectures so that they can be easily followed by system and hardware designers to develop en/decoder implementations that meet error-correcting performance and cost requirements. This book can be also used as a reference for graduate-level courses on VLSI design and error-correcting coding. Particular emphases are placed on hard- and soft-decision Reed-Solomon (RS) and Bose-Chaudhuri-Hocquenghem (BCH) codes and binary and non-binary low-density parity-check (LDPC) codes. These codes are among the best candidates for modern and emerging applications due to their good error-correcting performance and lower implementation complexity compared to other codes. To help explain the computations and en/decoder architectures many examples and case studies are included. More importantly discussions are provided on the advantages and drawbacks of different implementation approaches and architectures.

Dam Safety Management / Gestion de la Sécurité des Barrages Pre operational phases of the dam life cycle / Phases de conception constructio

Dam Safety Management / Gestion de la Sécurité des Barrages Pre operational phases of the dam life cycle / Phases de conception constructio

Dam Safety Management is a major concern during the entire lifetime cycle of a dam scheme. This is particularly true for the operational phase of the scheme that represents by far the longest period in its lifetime cycle. Bulletin 154 presented a general approach and concepts to be applied to dam operation. The current Bulletin 175 extends the developed concepts to all phases preceding the operational phase. Many risks associated with the operation of existing dams have their origins in other phases preceding the actual operation. Although there are numerous ICOLD Bulletins addressing technical aspects of planning design construction and commissioning of dams there is not a single Bulletin which covers the subject in a comprehensive manner. The current document is a first attempt to capture all relevant dam safety aspects in all preoperational phases by systematically characterizing the actors involved their roles the activities and complex interactions present in different phases of the dam lifecycle. An Overarching Safety Management System is specifically developed that can be applied to all actors involved. La gestion de la sécurité des barrages est une préoccupation majeure pendant tout le cycle de vie d'un projet de barrage. Cela est particulièrement vrai pour la phase opérationnelle du système qui représente de loin la période la plus longue de son cycle de vie. Le Bulletin 154 présente une approche générale et des concepts à appliquer à l'exploitation des barrages. Le Bulletin 175 actuel étend les concepts développés à toutes les phases précédant la phase d'exploitation. De nombreux risques associés à l'exploitation des barrages existants ont leur origine dans d'autres phases précédant l'exploitation proprement dite. Bien qu'il existe de nombreux bulletins ICOLD traitant des aspects techniques de la planification de la conception de la construction et de la mise en service des barrages il n'existe pas un seul bulletin qui couvre le sujet de manière exhaustive. Le document actuel est une première tentative de capturer tous les aspects pertinents de la sécurité des barrages dans toutes les phases pré-opérationnelles en caractérisant systématiquement les acteurs impliqués leurs rôles les activités et les interactions complexes présentes dans les différentes phases du cycle de vie du barrage. Un système global de gestion de la sécurité est spécifiquement développé et peut être appliqué à tous les acteurs impliqués. | Dam Safety Management / Gestion de la Sécurité des Barrages Pre operational phases of the dam life cycle / Phases de conception constructio

Environmental Fluid Mechanics - Méchanique des Fluides Environnementaux

Environmental Fluid Mechanics - Méchanique des Fluides Environnementaux

Dams are planned constructed and operated to meet human needs - generation of energy irrigated agricultural production flood control public and industrial supply supply of drinking water and various other purposes. Dams impound water in reservoirs during times of high flood that can be used for human requirements during times with inadequate natural flows. Positive impacts of dams are improved flood control improved welfare resulting from new access to irrigation and drinking water. Without dams there would be insufficient food to feed the world’s people and energy would be generated by burning fossil fuels that produce greenhouse gases. Despite this progress there remain significant concerns about the environmental impacts of dams. These environmental impacts are complex and far reaching remote of the dam and may occur in time with the dam construction or later and may lead to a loss of biodiversity and of productivity of natural resources. This bulletin compiles improvements in knowledge and state of the art technology to avoid or mitigate environmental impacts of dams on the natural ecosystem as well as to the people that depend upon them for their livelihood and also addresses the mitigation of environmental impacts on dams and reservoirs. Les barrages sont planifiés construits et exploités de manière à répondre aux besoins humains. Les barrages retiennent l'eau dans les réservoirs pendant les périodes de forte crue une eau qui peut être utilisée pour les besoins de l'homme pendant les périodes d’insuffisance des débits naturels. Les impacts positifs de barrages sont le contrôle des crues et l'amélioration du bien-être résultant du nouvel accès à l'irrigation et à l'eau potable. Sans barrages la production alimentaire serait insuffisante pour nourrir la population du globe et l'énergie serait générée en brûlant des combustibles fossiles qui produisent des gaz à effet de serre. Malgré ces progrès d'importantes préoccupations subsistent quant aux retombées des barrages sur l’environnement. Les impacts environnementaux sont complexes et d’une grande portée. Ils peuvent se produire au moment de la construction du barrage ou plus tard et peuvent entraîner une perte de la biodiversité et de la productivité des ressources naturelles. Le présent bulletin compile l'amélioration des connaissances et des technologies les plus récentes pour éviter ou atténuer les impacts environnementaux des barrages sur l'écosystème naturel ainsi que pour les personnes qui en dépendent pour leur subsistance. Il aborde également l'atténuation des impacts environnementaux sur les barrages et les réservoirs. | Environmental Fluid Mechanics - Méchanique des Fluides Environnementaux

ERGOCHECK for a Preliminary Mapping of Risk at Work Tools Guidelines and Applications

ERGOCHECK for a Preliminary Mapping of Risk at Work Tools Guidelines and Applications

One of the latest developments being pursued by the World Health Organization (WHO) and other international organizations (ILO ISO) in relation to preventing work-related diseases and disorders concerns the creation of toolkits and within them of simple tools. This book suggests a methodology and a comprehensive simple tool (ERGOCHECK downloadable for free from the website www. epmresearch. org) for bringing together various potential risk factors to undertake a preliminary mapping of discomfort/danger in the workplaces and to assess consequent priorities for prevention especially (but not only) in small and very small businesses. The tool is primarily designed to be used by employers OSH (Occupational Health and Safety) operators and trade union representatives but it may also be useful for occupational medical staff conducting periodical inspections and drafting health surveillance protocols and for supervisory bodies (labor inspectors) conducting inspections in the workplace needing to rapidly detect potentially dangerous situations requiring specific preventive interventions. Daniela Colombini is a certified European ergonomist and a senior researcher at the Research Unit Ergonomics of Posture and Movement Milan where she developed methods for the analysis evaluation and management of risk and damage from occupational biomechanical overload.
