This book was released on 2007-10-23 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a course given to talented high-school students at Ohio University in 1988, this book is essentially an advanced undergraduate textbook about the mathematics of fractal geometry. It nicely bridges the gap between traditional books on topology/analysis and more specialized treatises on fractal geometry. The book treats such topics as metric spaces, measure theory, dimension theory, and even some algebraic topology. It takes into account developments in the subject matter since 1990. Sections are clear and focused. The book contains plenty of examples, exercises, and good illustrations of fractals, including 16 color plates.

You will learn how to make those tweaks on some of the ready-made filters, and in the final recipe we will create a filter from scratch. This practical book also contains recipes showing how to use Inkscape as a raster editor and how to achieve photo-realistic effects in Inkscape. For each important technique and skill, you'll see some simple recipes, then some more advanced recipes followed by an explanation of how Inkscape works to produce the desired effects in your illustrations. By the end of this book you will be confident enough to create your own vector-based graphics with Inkscape. Get solutions to common graphic problems to achieve photo-realistic effects with Inkscape.

Download or read book Handbook to Roman Legionary Fortresses written by M.C. Bishop and published by Pen and Sword. This book was released on 2013-01-08 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: An extensive guide to the legionary fortresses of the Roman Empire, including locations, history, layout, and more. This is a reference guide to Roman legionary fortresses throughout the former Roman Empire, of which approximately eighty-five have been located and identified. With the expansion of the empire and the garrisoning of its army in frontier regions during the 1st century AD, Rome began to concentrate its legions in large permanent bases. Some have been thoroughly explored while others are barely known, but this book brings together for the first time the legionary fortresses of the whole empire. An introductory section outlines the history of legionary bases and their key components. At the heart of the book is a referenced and illustrated catalogue of the known bases, each with a specially prepared plan and an aerial photograph. A detailed bibliography provides up-to-date publication information. The book includes a website providing links to sites relevant to particular fortresses and a Google Earth file containing all of the known fortress locations.

Available in PDF, EPUB and Kindle. Book excerpt: You've experienced the shiny, point-and-click surface of your Linux computer--now dive below and explore its depths with the power of the command line. The Linux Command Line takes you from your very first terminal keystrokes to writing full programs in Bash, the most popular Linux shell (or command line). Along the way you'll learn the timeless skills handed down by generations of experienced, mouse-shunning gurus: file navigation, environment configuration, command chaining, pattern matching with regular expressions, and more. In addition to that practical knowledge, author William Shotts reveals the philosophy behind these tools and the rich heritage that your desktop Linux machine has inherited from Unix supercomputers of yore. As you make your way through the book's short, easily-digestible chapters, you'll learn how to: • Create and delete files, directories, and symlinks • Administer your system, including networking, package installation, and process management • Use standard input and output, redirection, and pipelines • Edit files with Vi, the world's most popular text editor • Write shell scripts to automate common or boring tasks • Slice and dice text files with cut, paste, grep, patch, and sed Once you overcome your initial "shell shock," you'll find that the command line is a natural and expressive way to communicate with your computer. Just don't be surprised if your mouse starts to gather dust.

Download or read book Human Chemistry (Volume One) written by Libb Thims and published by Lulu.com. This book was released on 2007-09-01 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human chemistry is the study of bond-forming and bond-breaking reactions between people and the structures they form. People often speak of having either good or bad chemistry together: whereby, according to consensus, the phenomenon of love is a chemical reaction. The new science of human chemistry is the study of these reactions. Historically, human chemistry was founded with the 1809 publication of the classic novella Elective Affinities, by German polymath Johann von Goethe, a chemical treatise on the origin of love. Goethe based his human chemistry on Swedish chemist Torbern Bergman's 1775 chemistry textbook A Dissertation on Elective Attractions, which itself was founded on Isaac Newton's 1687 supposition that the cause of chemical phenomena may 'all depend upon certain forces by which the particles of bodies, by some causes hitherto unknown, are either mutually impelled towards each other, and cohere in regular figures, or are repelled and recede from one another'; which thus defines life.
