The study of combinatorial block designs is a vibrant area of combinatorial mathematics with connections to finite geometries, graph theory, coding theory and statistics. The practice of ordering combinatorial objects can trace its roots to bell ringing which originated in 17th century England, but only emerged as a significant modern research area with the work of F. Gray and N. de Bruijn. These two fascinating areas of mathematics are brought together for the first time in this book. It presents new terminology and concepts which unify existing and recent results from a wide variety of sources. In order to provide a complete introduction and survey, the book begins with background material on combinatorial block designs and combinatorial orderings, including Gray codes -- the most common and well-studied combinatorial ordering concept -- and universal cycles. The central chapter discusses how ordering concepts can be applied to block designs, with definitions from existing (configuration orderings) and new (Gray codes and universal cycles for designs) research. Two chapters are devoted to a survey of results in the field, including illustrative proofs and examples. The book concludes with a discussion of connections to a broad range of applications in computer science, engineering and statistics. This book will appeal to both graduate students and researchers. Each chapter contains worked examples and proofs, complete reference lists, exercises and a list of conjectures and open problems. Practitioners will also find the book appealing for its accessible, self-contained introduction to the mathematics behind the applications.

A must-have for every quilter: the ultimate pattern resource, with an astounding 5,500 blocks With 5,500 blocks to copy, adapt, and combine in countless ways, no quilter will ever have to run out of patterns anymore. Some designs are classics and taken from museum collections, handed from friend to friend, or kept in a family for many years. Each pattern is drawn on a grid showing the number of squares to the block which makes it easy to mix-and-match, because they all draft to the same size. The dazzling choices include a Premium Star, Double Pyramid, Strips and Squares, Farmer's Puzzle, Sunburst, Beggar's Blocks, and countless more. They're arranged by type--including 4-, 5-, and 9-patch patterns; circles and curves; octagons; diamonds; and 8-point stars--and all indexed alphabetically by name. There's even information on each block's source. As a special bonus Maggie Malone has included a section of Alphabet Patch Patterns to use for personalizing every block. No quilter can do without this book.

Combinatorial mathematicians and statisticians have made a wide range of contributions to the development of block designs, and this book brings together much of that work. The designs developed for a specific problem are used in a variety of different settings. Applications include controlled sampling, randomized response, validation and valuation studies, intercropping experiments, brand cross-effect designs, lotto and tournaments.The intra- and inter- block, nonparametric and covariance analysis are discussed for general block designs, and the concepts of connectedness, orthogonality, and all types of balances in designs are carefully summarized. Readers are also introduced to the designs currently playing a prominent role in the field: alpha designs, trend-free designs, balanced treatment-control designs, nearest neighbor designs, and nested designs.This book provides the important background results required by researchers in block designs and related areas and prepares them for more complex research on the subject.

Presents an account of the theory and applications of incomplete block designs. This title considers various major aspects of incomplete block designs by consolidating material from the literature - the classical incomplete block designs, like the balanced incomplete block (BIB) and partially balanced incomplete block (PBIB) designs.

"Breaking designer's Block is a vast collection of some of the most varied work from the world's leading designers. This book is broken down into three core areas, color, which presents both a historical look at color palettes and collection of work that is driven by the designer's color choices, type, which also presents a historical look at various fonts as well as a collection of twelve top typographic designers, and materials, which presents a wide array of graphic design pieces that have incorporated imaginative materials to drive a message, such as fur-covered books and Christmas cards stitched on men's briefs. This exceptional collection clearly demonstrates the remarkable power that designers have to engender wonder, excitement, and a sense of ownership in today's consumers. An invaluable resource for fresh ideas, "Breaking Designer's Block will stimulate and inspire designers to open their minds--and their art--to create work that is memorable, thought provoking, and visually driven.

DIVPacked with photographs and diagrams for 75 quilt blocks, The Quilt Block Book teaches you three basic block construction methods to get you started in the world of quilt blocks. The blocks are divided into three sections by technique: quick piecing, foundation (paper) piecing, and appliqué blocks. Each section includes basic technique instruction, followed by 25 blocks. Follow the step-by-step instructions to quickly learn the order of construction and directions for pressing seam allowances, while color diagrams of the blocks show them used in multiples so you can plan out your full quilt as you go along./divDIV/divDIVThe perfect mix of original designs and modern interpretations of traditional patterns, this book offers something for both the beginner and experienced quilter. Each block can be interpreted in endless fabric combinations, so you’ll gain a wealth of inspiration. Whether you choose to use the blocks for full quilts, small décor pieces, or even fashion accents is completely up to you./divDIV/divDIVLinks to online patterns make it easy for you to print out patterns for the blocks in the size you want. Paper-pieced blocks can be printed out on paper to go straight from printer to sewing machine; no tracing necessary./divDIV/divDIVThe author's unique approach to foundation piecing provides the full patterns plus the option of individual rough-cut templates for each segment that prevent inadequate coverage. Patterns for quick-pieced and appliqué blocks include seam allowances, so you can forget about having to draw templates and add seam allowances./div

Design Theory, Second Edition presents some of the most important techniques used for constructing combinatorial designs. It augments the descriptions of the constructions with many figures to help students understand and enjoy this branch of mathematics. This edition now offers a thorough development of the embedding of Latin squares and combinatorial designs. It also presents some pure mathematical ideas, including connections between universal algebra and graph designs. The authors focus on several basic designs, including Steiner triple systems, Latin squares, and finite projective and affine planes. They produce these designs using flexible constructions and then add interesting properties that may be required, such as resolvability, embeddings, and orthogonality. The authors also construct more complicated structures, such as Steiner quadruple systems. By providing both classical and state-of-the-art construction techniques, this book enables students to produce many other types of designs.
