This volume contains topics such as algorithms and data structures, approximation algorithms, combinatorial optimization, computational biology, computational complexity, computational geometry, cryptography, experimental algorithm methodologies, graph drawing and graph algorithms, internet algorithms, online algorithms, parallel and distributed algorithms, quantum computing and randomized algorithms.

Welcome to the world of dinosaurs! Here you will find work-jobs and activities to make your Dinosaur Learning Center more complete. The work-jobs included can be photocopied or duplicated directly onto construction paper or manila tag. Instructions are included for each and are easy to follow. Some of the topics included are: Meat Eaters, Plant Eaters, Two Legs, Four Legs, I am a Dinosaur, Dinosaur Country, Fossil Match, Dinosaur Bone Hunt, Dinosaur Songs, Mega Puzzles, and Activity Cards. The center book pages are for creative development. Each child can create a booklet of his or her dinosaur studies. This Animal Science lesson provides a teacher and student section with reading passages, activities, word search, and board game to create a well-rounded lesson plan.

This book introduces a range of image color feature extraction techniques. Readers are encouraged to try implementing the techniques discussed here on their own, all of which are presented in a very simple and step-by-step manner. In addition, the book can be used as an introduction to image color feature techniques for those who are new to the research field and software. The techniques are very easy to understand as most of them are described with pictorial examples. Not only the techniques themselves, but also their applications are covered. Accordingly, the book offers a valuable guide to these tools, which are a vital component of content-based image retrieval (CBIR).

Imagine a softly striped crib blanket knit in the comforting colors of the nursery. Or a sophisticated cashmere wrap featuring rich jewel tones that set off a favorite black dress. Knitting teacher and author Margaret Radcliffe presents a world of color techniques in a single comprehensive reference that you’ll consult every time two or more yarn colors are in play. Stitchers of every ability level will love the color-combining methods and professional secrets revealed in The Essential Guide to Color Knitting Techniques. Multicolor knitting techniques are explained with step-by-step illustrations and photographs accompanied by instructive text. Complete chapters on stripes, stitch effects, succeeding with multicolor yarns, stranded knitting, and intarsia cover the theory and how-to behind each method and offer creative solutions for handling tangled yarn, estimating yarn quantities of each color, holding on to all those ends, and employing stunning finishing techniques. A final chapter describes more unusual techniques, such as helix, shadow, mosaic, and modular knitting.
