Implicit Curves and Surfaces: Mathematics, Data Structures and Algorithms

Implicit Curves and Surfaces: Mathematics, Data Structures and Algorithms

Implicit Curves and Surfaces: Mathematics, Data Structures and Algorithms

Product Description

Implicit objects have gained increasing importance in geometric modeling, visualisation, animation, and computer graphics, because their geometric properties provide a good alternative to traditional parametric objects. This book presents the mathematics, computational methods and data structures, as well as the algorithms needed to render implicit curves and surfaces, and shows how implicit objects can easily describe smooth, intricate, and articulatable shapes, and hence why they are being increasingly used in graphical applications.

Divided into two parts, the first introduces the mathematics of implicit curves and surfaces, as well as the data structures suited to store their sampled or discrete approximations, and the second deals with different computational methods for sampling implicit curves and surfaces, with particular reference to how these are applied to functions in 2D and 3D spaces.

Distributed Autonomous Robotic Systems 8

Product Description

The International Symposia on Distributed Autonomous Robotic Systems (DARS) started at Riken, Japan in 1992. Since then, the DARS symposia have been held every two years. The 9th DARS symposium, which was held during November 17–19 in Tsukuba, Japan, hosted 84 participants from 13 countries. The 48 papers presented there were selected through rigorous peer review with a 50% acceptance ratio. Along with three invited talks, they addressed the spreading research fields of DARS, which are classifiable along two streams: theoretical and standard studies of DARS, and interdisciplinary studies using DARS concepts. The former stream includes multi-robot cooperation (task assignment methodology among multiple robots, multi-robot localization, etc.), swarm intelligence, and modular robots. The latter includes distributed sensing, mobiligence, ambient intelligence, and multi-agent systems interaction with human beings.

This book not only offers readers the latest research results related to DARS from theoretical studies to application-oriented ones; it also describes the present trends of this field. With the diversity and depth revealed herein, we expect that DARS technologies will flourish soon.

Wastewater Treatment in Constructed Wetlands with Horizontal Sub-Surface Flow

Wastewater Treatment in Constructed Wetlands with Horizontal Sub-Surface Flow

Wastewater Treatment in Constructed Wetlands with Horizontal Sub-Surface Flow

Product Description

Constructed wetlands with horizontal sub-surface flow (HF CWs) have been used for wastewater treatment for more than four decades. HF CWs are used around the world for many types of wastewater, including municipal sewage, agricultural and industrial wastewaters, runoff waters, wastewaters containing endocrine-disrupting chemicals, and landfill leachate.

This book fills a gap in the literature by providing an extensive, worldwide overview of this treatment technology. Special attention is paid to assessing the use of this treatment technology in individual countries and treatment performance of various HF CWs with respect to major pollutants in different types of wastewater.

The book provides a broad base of knowledge, including:

  • processes occurring in wetland soils and overlying water
  • various types of constructed wetlands for wastewater treatment
  • detailed information about design parameters, functioning, operation and maintenance, and costs of HF CWs
  • evaluations of treatment efficiency of HF CWs under diverse conditions
  • information on the global use of HF CWs for various types of wastewater

The inclusion of case studies from over 50 countries and more than 250 colour photos that illustrate the science makes this an invaluable text.

This book will be useful not only to wetland scientists, teachers, and engineers, but also to landscape planners, ecologists, wastewater-treatment designers and governmental decision-makers.

Ambient Findability by Peter Morville

Ambient Findability by Peter Morville

Ambient Findability by Peter Morville

Product Description
How do you find your way in an age of information overload? How can you filter streams of complex information to pull out only what you want? Why does it matter how information is structured when Google seems to magically bring up the right answer to your questions? What does it mean to be “findable” in this day and age? This eye-opening new book examines the convergence of information and connectivity. Written by Peter Morville, author of the groundbreaking Information Architecture for the World Wide Web, the book defines our current age as a state of unlimited findability. In other words, anyone can find anything at any time. Complete navigability.

Morville discusses the Internet, GIS, and other network technologies that are coming together to make unlimited findability possible. He explores how the melding of these innovations impacts society, since Web access is now a standard requirement for successful people and businesses. But before he does that, Morville looks back at the history of wayfinding and human evolution, suggesting that our fear of being lost has driven us to create maps, charts, and now, the mobile Internet.

The book’s central thesis is that information literacy, information architecture, and usability are all critical components of this new world order. Hand in hand with that is the contention that only by planning and designing the best possible software, devices, and Internet, will we be able to maintain this connectivity in the future. Morville’s book is highlighted with full color illustrations and rich examples that bring his prose to life.

AppleScript: The Definitive Guide, 2nd Edition

AppleScript: The Definitive Guide, 2nd Edition

Product Description
Mac users everywhere–even those who know nothing about programming–are discovering the value of the latest version of AppleScript, Apple’s vastly improved scripting language for Mac OS X Tiger. And with this new edition of the top-selling AppleScript: The Definitive Guide, anyone, regardless of your level of experience, can learn to use AppleScript to make your Mac time more efficient and more enjoyable by automating repetitive tasks, customizing applications, and even controlling complex workflows.

Fully revised and updated–and with more and better examples than ever–AppleScript: The Definitive Guide, 2nd Edition explores AppleScript 1.10 from the ground up. You will learn how AppleScript works and how to use it in a variety of contexts: in everyday scripts to process automation, in CGI scripts for developing applications in Cocoa, or in combination with other scripting languages like Perl and Ruby.

AppleScript has shipped with every Mac since System 7 in 1991, and its ease of use and English-friendly dialect are highly appealing to most Mac fans. Novices, developers, and everyone in between who wants to know how, where, and why to use AppleScript will find AppleScript: The Definitive Guide, 2nd Edition to be the most complete source on the subject available. It’s as perfect for beginners who want to write their first script as it is for experienced users who need a definitive reference close at hand.

AppleScript: The Definitive Guide, 2nd Edition begins with a relevant and useful AppleScript overview and then gets quickly to the language itself; when you have a good handle on that, you get to see AppleScript in action, and learn how to put it into action for you. An entirely new chapter shows developers how to make your Mac applications scriptable, and how to give them that Mac OS X look and feel with AppleScript Studio. Thorough appendixes deliver additional tools and resources you won’t find anywhere else. Reviewed and approved by Apple, this indispensable guide carries the ADC (Apple Developer Connection) logo.

About the Author
