Book Description
Computers are now being used virtually everywhere in arts, drafting, and design to generate curves and surfaces ranging from the elementary to the intricate. Practical Handbook of Curve Design and Generation is a ready reference that presents the basic mathematics of curves in a complete, clear manner that enables you to apply the material to your own work with minimum effort. By knowing how curves are mathematically generated and how their shape is controlled, you can more fully exploit available computer tools, modify these tools themselves, and provide input for others to modify them. It will also help you to identify mathematical equations required to produce specific curves. The book does not require a heavy mathematical background-if you understand elementary algebra and trigonometry, you can fully apply the material presented. Essential mathematical concepts are repeated in the book to reinforce your knowledge of those topics. Featuring some 300 graphic examples, the book is organized so that early chapters cover fundamental polynomial, trigonometric, and exponential forms. The mathematical transformation of curves is then treated in order to give you a general approach for modifying known curves. Later chapters introduce complex curves that can be composed from the building blocks presented in earlier chapters. The final chapters cover interesting ideas in space curves and in surfaces.

Book Description
Langston Hughes electrified readers and launched a renaissance in Black writing in America—the poems in this collection were chosen by Hughes himself shortly before his death and represent stunning work from his entire career. The poems Hughes wrote celebrated the experience of invisible men and women: of slaves who "rushed the boots of Washington"; of musicians on Lenox Avenue; of the poor and the lovesick; of losers in "the raffle of night." They conveyed that experience in a voice that blended the spoken with the sung, that turned poetic lines into the phrases of jazz and blues, and that ripped through the curtain separating high from popular culture. They spanned the range from the lyric to the polemic, ringing out "wonder and pain and terror—and the marrow of the bone of life." The collection includes "The Negro Speaks of Rivers," "The Weary Blues," "Still Here," "Song for a Dark Girl," "Montage of a Dream Deferred," and "Refugee in America." It gives us a poet of extraordinary range, directness, and stylistic virtuosity.

Book Description
The ultimate ophthalmic dispensing reference, this book provides a step-by-step system for properly fitting and adjusting eyewear. It covers every aspect of dispensing — from basic terminology to frame selection to eyewear fitting, adjusting, and repairing. Perfect for both students who are just learning about dispensing and practitioners who want to keep their skills up to date, this resource offers in-depth discussions of all types of lenses, including multifocal, progressive, absorptive, safety, recreational, aspheric, and high index. Plus, it goes beyond the basics to explore the "how" and "why" behind lens selection, to help you better understand and meet your patients' vision needs. - A glossary of key terms provides easy access to definitions. - Proficiency tests at the end of each chapter reinforce your understanding of the material through multiple-choice, fill-in-the-blank, matching, and true/false questions. - A new full-color design with hundreds of illustrations that clearly demonstrate key procedures, concepts, and techniques. - Updated coverage of the latest dispensing procedures and equipment. - Detailed information on the newest types of lenses, including progressive, absorptive, aspheric, and atoric. - Updated photos feature more current frames and lenses, keeping the book up to date with today's eye care trends.

Book Description
Handbook of Grid Generation addresses the use of grids (meshes) in the numerical solutions of partial differential equations by finite elements, finite volume, finite differences, and boundary elements. Four parts divide the chapters: structured grids, unstructured girds, surface definition, and adaption/quality. An introduction to each section provides a roadmap through the material. This handbook covers: Fundamental concepts and approaches Grid generation process Essential mathematical elements from tensor analysis and differential geometry, particularly relevant to curves and surfaces Cells of any shape - Cartesian, structured curvilinear coordinates, unstructured tetrahedra, unstructured hexahedra, or various combinations Separate grids overlaid on one another, communicating data through interpolation Moving boundaries and internal interfaces in the field Resolving gradients and controlling solution error Grid generation codes, both commercial and freeware, as well as representative and illustrative grid configurations Handbook of Grid Generation contains 37 chapters as well as contributions from more than 100 experts from around the world, comprehensively evaluating this expanding field and providing a fundamental orientation for practitioners.
