Shaping The Surface

Shaping the Surface explores the history of modern British architecture through the lens of surface, materiality and decoration. Picking up on a trait that art historian Nikolaus Pevsner first identified as a 'national mania for beautiful surface quality', this book makes a new contribution to architectural history and visual culture in its detailed examination of the surfaces of British architecture from the middle of the 19th century up to the turn of the 21st century. Tracing this continuing sensibility to surface all the way through to the modern era, it explores how and why surface and materiality have featured so heavily in recent architectural tradition, examining the history of British architecture through a selection of key cultural moments and movements from Romanticism and the Arts and Crafts, to Brutalism, High-Tech, Post-Modernism, Neo-Vernacular, and the New Materiality. Embedded within the narrative is the question of whether such national characters can exist in architecture at all – and indeed the extent to which it is possible to identify a British architectural consciousness in an architectural tradition characterised by its continuous importation of theories, ideas, materials and people from around the globe. Shaping the Surface provides a deep critique and meditation on the importance of surface and materiality for architects, designers, and historians everywhere - in Britain and beyond - while it also serves as a thematic introduction to modern British architectural history, with in-depth readings of the works of many key British architects, artists, and critics from Ruskin and William Morris to Alison and Peter Smithson, Eduardo Paolozzi, Richard Rogers and Caruso St John.

Laser Beam Shaping: Theory and Techniques addresses the theory and practice of every important technique for lossless beam shaping. Complete with experimental results as well as guidance on when beam shaping is practical and when each technique is appropriate, the Second Edition is updated to reflect significant developments in the field. This authoritative text: Features new chapters on axicon light ring generation systems, laser-beam-splitting (fan-out) gratings, vortex beams, and microlens diffusers Describes the latest advances in beam profile measurement technology and laser beam shaping using diffractive diffusers Contains new material on wavelength dependence, channel integrators, geometrical optics, and optical software Laser Beam Shaping: Theory and Techniques, Second Edition not only provides a working understanding of the fundamentals, but also offers insight into the potential application of laser-beam-profile shaping in laser system design.

This book is the printed edition of the Special Issue published in Materials. The book provides an overview of current international research activities in the field of friction and wear management through the laser processing of periodic surface micro- and nanostructures for technical and medical applications. Contributions of renowned scientists from academia and industry provide a bridge between the fields of tribology and laser material processing in order to foster current knowledge and present new ideas for future applications and new technologies.

Describes how erosion caused by water, wind, ice, and weathering are part of the rock cycle and are responsible for the changes in the Earth's surface.

While light is required to make a photograph, light alone is not enough. More often, it is the way the light has been modified and shaped that brings an image to life. In this book, Glenn Rand and Tim Meyer offer a comprehensive approach to the tools and techniques photographers can use to shape the light—creating the style, energy, emotion, and feeling that make a photograph exceptional. Clear text is paired with ample before-and-after images and diagrams to make learning easy. Beginning with the physics of light, the authors show you how to predict light’s interaction with the surface of the subject/object you are photographing. Based on this, you can begin to make informed decisions about what kinds of modifiers will help you achieve the look you want. Using softboxes, umbrellas, masks, gels, reflectors, and more, you’ll learn to precisely control the light’s diffused edge and ratio for precise, flawless results.

This new edition details the important features of beam shaping and exposes the subtleties of the theory and techniques that are best demonstrated through proven applications. New chapters cover illumination light shaping in optical lithography; optical micro-manipulation of live mammalian cells through trapping, sorting, and transfection; and laser beam shaping through fiber optic beam delivery. The book discusses applications in lithography, laser printing, optical data storage, stable isotope separation, and spatially dispersive lasers. It also provides a history of the field and includes extensive references.

Selective Laser Melting (SLM), also referred to as Laser Powder Bed Fusion (L-PBF), offers significant advantages for the manufacturing of complex, high-quality parts. However, its market share is still small compared to conventional manufacturing technologies. Major drawbacks hindering an industrial ramp-up are low productivity, high part costs and issues with quality and reproducibility. Comprehensive research has been done to overcome these challenges, but little attention has been paid to addressing them by optimizing the laser beam profile. Therefore, the author examines the effect of the laser beam profile on the productivity and process stability through both numerical and experimental investigations. The results show clear advantages an optimized laser beam profile offers.
