This book covers water quality indices (WQI) in depth - it describes what purpose they serve, how they are generated, what are their strengths and weaknesses, and how to make the best use of them. It is a concise and unique guide to WQIs for chemists, chemical/environmental engineers and government officials.
Whereas it is easy to express the quantity of water, it is very difficult to express its quality because a large number of variables determine the water quality. WQIs seek to resolve the difficulty by translating a set of a large number of variables to a one-digit or a two-digit numeral. They are essential in communicating the status of different water resources in terms of water quality and the impact of various factors on it to policy makers, service personnel, and the lay public. Further they are exceedingly useful in the monitoring and management of water quality.
With the importance of water and water quality increasing exponentially, the importance of this topic is also set to increase enormously because only with the use of indices is it possible to assess, express, communicate, and monitor the overall quality of any water source.
- Provides a concise guide to WQIs: their purpose and generation
- Compares existing methods and WQIs and outlines strengths and weaknesses
- Makes recommendations on how the indices should be used and under what circumstances they apply

Exploiting Nonlinear Behavior in Structural Dynamics
Author: Lawrie Virgin, David Wagg (auth.), David J. Wagg, Lawrence Virgin (eds.) | Size: 6 MB | Format:PDF | Quality:Original preprint | Publisher: Springer Vienna | Year: 2012 | pages: 280 | ISBN: 978-3-7091-1186-4, 978-3-7091-1187-1
The articles in this volume give an overview and introduction to nonlinear phenomena in structural dynamics. Topics treated are approximate methods for analyzing nonlinear systems (where the level of nonlinearity is assumed to be relatively small), vibration isolation, the mitigation of undesirable torsional vibration in rotating systems utilizing specifically nonlinear features in the dynamics, the vibration of nonlinear structures in which the motion is sufficiently large amplitude and structural systems with control.

Stochastic Structural Dynamics: Application of Finite Element Methods
Author: Cho W. S. To | Size: 13 MB | Format:PDF | Quality:Unspecified | Publisher: Wiley | Year: 2013 | Pages: 350 | ISBN: 1118342356, 9781118342350
The parallel developments of the Finite Element Methods in the 1950’s and the engineering applications of stochastic processes in the 1940’s provided a combined numerical analysis tool for the studies of dynamics of structures and structural systems under random loadings. In the open literature, there are books on statistical dynamics of structures and books on structural dynamics with chapters dealing with random response analysis. However, a systematic treatment of stochastic structural dynamics applying the finite element methods seems to be lacking. Aimed at advanced and specialist levels, the author presents and illustrates direct integration methods for analyzing the statistics of the response of structures to stochastic loads. The analysis methods are based on structural models represented via the Finite Element Method. In addition to stationary linear problems the text also addresses non-stationary excitation and systems with spatially stochastic property variations.
Key features:
- A systematic treatment of stochastic structural dynamics applying the finite element methods
- Highly illustrated throughout and aimed at advanced and specialist levels, it focuses on computational aspects instead of theory
- Emphasizes results mainly in the time domain with limited contents in the frequency domain
- Presents and illustrates direct integration methods for analyzing the statistics of the response of structures to stochastic loads.

Optimization techniques offer immense potential for the improvement of performance-driven design, since they allow the adoption of an holistic approach. This can lead to great advantages: optimal design solutions can be properly identified only if all criteria are considered at the same time, rather than separately. There are two barriers which obstruct optimization from being applied to building design: a technological barrier (applying the algorithms is not easy and can be quite time-consuming) and a cultural one (architects and engineers are required to change their perspectives as the design process has to be handled in a new way). This book explores these barriers from the perspective of both engineers and architects, and proposes a change in the attitudes of these two “actors”: an engineer and an architect develop a dialog which helps them understand each other’s perspective; in this way they find how they must both make a step forward.

Author: Robert W. Sarsby | Size: 70 MB | Format:PDF | Quality:Original preprint | Publisher: Institution of Civil Engineers (ICE) | Year: 2013 | Pages: 520 | ISBN: 9780727741875, 072774187X
Environmental Geotechnics is a forward-thinking guide to aid engineers in applying geotechnical principles, processes and techniques in a way that will not only reduce their environmental impact but aim to benefit the environment.
The major construction-environment interface is geotechnical in nature. For engineers to be able to foresee environmental problems and modify construction projects, or derive novel approaches, to prevent negative impacts from their works, they need a thorough knowledge of their subject and a constant awareness of the ‘pollution-output’ of any construction operation.
Environment Geotechnics draws on the author’s extensive personal experience to provide a thorough coverage of the key components of environmental geotechnics, enabling engineers to identify and convert complex environmental problems into situations which can be accurately analysed. Revisions in this second edition include a new chapter on foundations and the key elements of design using Eurocode 7, and revised coverage of radioactive waste management and the requirements for safe disposal; construction waste management, including the use of waste as a construction material; geosynthetics and geomembranes.
With illustrative examples on a variety of geotechnical topics, investigation methods and common problems, Environmental Geotechnics demonstrates the applications of geotechnical principles to practical construction, uniquely coupling comprehensive coverage of all aspects of geotechnical engineering with in-depth explanation of ground engineering situations which involve major interaction with the environment.
Environmental Geotechnics is an essential guide for construction professionals wishing to understand the latest concerns and developments on the construction-environmental interface as well as a textbook for all those involved in the study of civil engineering, engineering geology and environmental geotechnics.

How to adapt existing building stock is a problem being addressed by local and state governments worldwide. In most developed countries we now spend more on building adaptation than on new construction and there is an urgent need for greater knowledge and awareness of what happens to commercial buildings over time.
Sustainable Building Adaptation: innovations in decision-making is a significant contribution to understanding best practice in sustainable adaptations to existing commercial buildings by offering new knowledge-based theoretical and practical insights. Models used are grounded in results of case studies conducted within three collaborative construction project team settings in Australia and the Netherlands, and exemplars are drawn from the Americas, Asia, Japan, Korea and Europe to demonstrate the application of the knowledge more broadly.
Results clearly demonstrate that the new models can assist with informed decision-making in adaptation that challenges some of the prevailing solutions based on empirical approaches and which do not accommodate the sustainability dimension. The emphasis is on demonstrating how the new knowledge can be applied by practitioners to deliver professionally relevant outcomes.
The book offers guidance towards a balanced approach that incorporates sustainable and optimal approaches for effective management of sustainable adaptation of existing commercial buildings.
