Most discussion about Web design seems to focus on the creative process, yet turning concept into reality requires a strong set of deliverablesthe documentation (concept model, site maps, usability reports, and more) that serves as the primary communication tool between designers and customers. Here at last is a guide devoted to just that topic. Combining quick tips for improving deliverables with in-depth discussions of presentation and risk mitigation techniques, author Dan Brown shows you how to make the documentation you're required to provide into the most efficient communications tool possible. He begins with an introductory section about deliverables and their place in the overall process, and then delves into to the different types of deliverables. From usability reports to project plans, content maps, flow charts, wireframes, site maps, and more, each chapter includes a contents checklist, presentation strategy, maintenance strategy, a description of the development process and the deliverable's impact on the project, and more.

This text offers design concepts such as interface design, design principles and elements, layout, content and typography, and color, as well as examples, projects, and code to enhance client and user interpretation and appreciation of web-based products.

This book is a comprehensive design guide summarising current best practice for the design of concrete pavements. Following an overview of the theory involved, the author details optimum design techniques and best practice, with a focus on highway and infrastructure projects. Worked examples and calculations are provided to describe standard design methods, illustrated with numerous case studies. The author provides guidance on how to use each method on particular projects, with reference to UK, European and US standards and codes of practice. Concrete Pavement Design: Guidance Notes is an essential handbook for civil engineers, consultants and contractors involved in the design and construction of concrete pavements. It will also be of interest to students of pavement design.

Crawford and Kaplan's J2EE Design Patterns approaches the subject in a unique, highly practical and pragmatic way. Rather than simply present another catalog of design patterns, the authors broaden the scope by discussing ways to choose design patterns when building an enterprise application from scratch, looking closely at the real world tradeoffs that Java developers must weigh when architecting their applications. Then they go on to show how to apply the patterns when writing realworld software. They also extend design patterns into areas not covered in other books, presenting original patterns for data modeling, transaction / process modeling, and interoperability.

This book does not provide any defined solutions or silver bullets. Integrating J2EE Platform applications with legacy systems is a difficult task that requires a thorough understanding of both legacy system applications and object-oriented design. We have tried to find a practical approach to applying the J2EE integration tier patterns in real-world situations, the main design principle being that of separation of concerns. Some of the designs described in this book are currently running in production, while others represent theoretical work that has not yet been tested in a full-scale production environment. We hope, however, that in reading this book you will gain valuable tools with which to start the long journey toward application integration.

The understanding of design in general and the structure of scientific research in design inevitably leads to discussions of the central categories for design. Constructive debate and struggles for acceptance fuel such a process—a process that, as a sign of fruitful further refinement, can never be completely finished. It is well known that such a development, especially in design, cannot be addressed without obstacles and indeed dissent. Even within a single cultural or linguistic realm, the positions are supposedly irreconcilable. Any undertaking that attempts to create understanding across cultural and linguistic borders is that much more ambitious.

Hotel architecture tends to look like office building architecture in some cases, and not that interesting office architecture, but the dull type. Fortunately, there are also cases of unique and well thought architectural plans for hotels, showcased in this article through a few examples. A small number of these are just projects or in construction, but the rest are just architectural marvels.

The software development community widely acknowledges that domain modeling is central to software design. Through domain modeling, software developers are able to express rich functionality and translate that functionality into software implementation that truly serves the needs of its users. Despite its obvious importance, however, there are few practical resources that show how to incorporate effective domain modeling into the software development process.

This unified treatment of curve and surface design concepts is the Fourth Edition of the popular text, Curves and Surfaces for Computer-Aided Geometric Design, Third Edition (Academic Press, 1992). Assuming only a background in calculus and basic linear algebra, this revised and updated classic is highly accessible and should be of interest to a wide audience; from computer graphics hobbyists to software developers for CAD/CAM systems. The author's informal style makes this book very reader-friendly, and the IBM disk included in the back of the book will allow the user to gain first-hand experience with the concepts as they are explained. This book focuses on Bezier and B-spline methods for curves, rational Bezier and B-spline curves, geometric continuity, spline interpolation, and Coons methods. In this Fourth Edition, the content has been thoroughly revised and updated to include a new chapter on recursive subdivision, new material on nonrectangular topology, surface faceting, stereo lithography, and new sections on triangulations and scattered data interpolants. The disk provided in the back of the book has also been updated to include all of the data sets and the C code used in the book.

The structural use of brick masonry has to some extent been hampered by its long history as a craft based material and some years ago its disappearance as a structural material was being predicted. The fact that this has not happened is a result of the inherent advantages of brickwork and the design of brick masonry structures has shown steady development, based on the results of continuing research in many countries. Nevertheless, structural brickwork is not used as widely as it could be and one reason for this lies in the fact that design in this medium is not taught in many engineering schools alongside steel and concrete. To help to improve this situation, the authors have written this book especially for students in university and polytechnic courses in structural engineering and for young graduates preparing for professional examination in structural design.

This book provides a consistent vocabulary and visual notation framework to describe large-scale integration solutions across many technologies.
