This comprehensive reference examines the changing role and design of library buildings, using a critical examination of recent examples from around the world.
The authors, who represent the views of the architect and the client, outline the history and changing typology of the library. They examine the new national, public, academic and specialist libraries using numerous international examples including Sri Lanka, Vancouver, Johannesburg, Paris and London. New design advice and technical data is presented to illustrate the many approaches that designers have taken in creating a building with many diverse functions. The book concludes with speculations about the future of the library as a place for storing, reflecting upon and exchanging knowledge.
Libraries are undergoing fundamental change as new technology liberates the library from its dependence upon the written word. Increasingly libraries are seen as learning resource centres with a smooth interface between computer-based access and traditional book and journal material.
* Comprehensive technical coverage of library planning & design gives a complete overview
* Excellent author team representing both architects and library services to give unbiased and informed opinions
* International case studies show the theory in practice

This book is intended to fill a knowledge gap in the study of contemporary high-rise living. While there has been much documentation on the engineering and technological aspects of tall buildings, relatively little has been written about the social and livability of high-rise. Much less is written about Asian cities even though Asia is the current hotbed of high-rise development. Even though traditional discourse of high-rise housing is not always positive, new forces are redefining its place in 21st century urbanity. Many cities around the world are reembracing high-rise in urban agenda under current narrative of sustainable development. High-rise is fast becoming a priority area in international research agenda. The quest is for livable and sustainable high-rise development. Against the background of current trends--globalization, urbanization, mixed-use development, and new-built taller buildings in inner city areas in both developed and developing countries, this book examines the software: design, economics, estate management, legal and property rights, physical environment, planning, community development, and social dimensions of high-rise living. Analysis is with the widely acclaimed successful high-rise public housing in Hong Kong and Singapore to understand the advantages and worries of high-rise living, and to distill the key points and lessons in the making of a ‘good’ highrise living environment. Hong Kong and Singapore have been constructing high-rise for more than four decades each. The majority of their population has moved to live in high-rise, selecting to live high-rise, and registering consistently high residential satisfaction. The height of apartment buildings in both cities continues to rise. The tallest is anticipated to be 70-storey. It is the contention of this book that contrary to earlier common negative discourses on public high-rise living, the high-rise environment may yet offer urban residents a satisfying dwelling experience. Leading housing academics, researchers and practitioners in the two cities have contributed to this book. This book presents a timely contribution to our understanding of a widening urban phenomenon that will affect a growing number of the world’s population.

The all-in-one interior detailing guide that unites creative and technical aspects
A well-executed interior space requires the successful combination of the creative and the technical. Interior Detailing bridges the gap between design and construction, and shows how to develop and transform design concepts into details that meet the constraints, functional requirements, and constructability issues that are part of any interior design element. It offers guidance on how design professionals can combine imaginative thinking and the application of technical resources to create interiors that are aesthetically pleasing, functionally superior, and environmentally sound. Interior Detailing:
* Includes 150 easy-to-understand details showing how to logically think through the design and development of an assembly so that it conforms to the designer's intent and meets the practical requirements of good construction
* Describes how to solve any detailing design problem in a rational way
* Contains conceptual and practical approaches to designing and detailing construction components thatform interior spaces
* Shows how a small number of principles can be used to solve nearly any detailing problem
This guide covers the subject of interior spaces comprehensively by balancing the contributions of physical beauty and structural integrity in one complete volume. By following the principles laid out in this book, interior designers and architects can plan for the construction of a unique interior environment more thoughtfully and with a clearer, better-defined purpose.

This book combines the essence of architecture and art, and explores how designers find new ways in which to balance the various contradictions and conflicts and to perfectly express their understanding of space and the owners' initial ideas and requirements. At the same time, each new project always contains many uncertain factors that refer to the furnishings or even space composition. Each of these factors seem to tell a never ending story and records people's feeling of excitement, confusion, recalling and longing. In order to illustrate the essence of interior design in a more accurate way, this book has systematically deconstructed every aspect of interior design that refers to space, structure, interface, decoration as well as special areas. Each aspect is highly detailed and illustrated from the point of functional area, besides, descriptive text and the corresponding plan vividly recur the transformation from plane to space, from the abstract to the intuition. Readers will not only find inspiration from the projects showcased in this book, but will also experience the peculiarity of interior design and enjoy the tactile sensation of the textured space.

A tutorial on genetic algorithms with an emphasis on practical applications
The rapidly expanding field of genetic algorithms has given rise to many new applications in a variety of disciplines. However, most of the existing books on the subject concentrate on theory. Practical Genetic Algorithms is the first introductory-level book to emphasize practical applications through the use of example problems.
In an accessible style, the authors explain why the genetic algorithm is superior in many real-world applications, cover continuous parameter genetic algorithms, and provide in-depth trade-off analysis of genetic algorithm parameter selection. Written for the end user in engineering, science, and computer programming, as well as upper-level undergraduate and graduate students, Practical Genetic Algorithms:
* Provides numerous practical example problems
* Contains over 80 illustrations
* Features many figures and tables
* Includes three appendices: a glossary of terms, a list of genetic algorithm routines in pseudocode, and a list of symbols used in the book.

Dredging is not only vital to maintain navigation, and therefore to international commerce, but also pays an important role in offshore engineering, the obtaining of aggregates for the construction industry, and in coastal defence works.
This guide highlights the particular problems of excavating from underwater sites and describes the methods and equipment developed to overcome them. All the stages of dredging are considered, from project design specification and site investigation, through production estimation and contractual issues, to supervision and management.
