Download or read book On the Problem of Equal ripple Power Pattern Synthesis written by Hans Steyskal and published by . This book was released on 1969 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report on antenna array pattern synthesis deals with the approximation of power patterns rather than the usual problem of approximating field patterns. After a qualitative comparison of the different characteristics an optimum approximation is formulated in general terms. The possibility of finding an exact 'equal ripple' solution is discussed, and an approximate 'equal ripple' solution is offered as an approach to this as yet unsolved mathematical problem. (Author).

Download or read book The Power of Pattern written by Susanna Salk and published by Rizzoli Publications. This book was released on 2018-09-11 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Featuring interiors by today’s top designers, The Power of Pattern shows how wallpaper and fabric designs can be used to elevate and personalize every room. Both a beautiful interiors book and a resource guide, it features a diversity of interiors and styles, showcasing the patterns themselves in full-page splendor. Best-selling interiors author Susanna Salk turns her focus to patterns, celebrating their versatility and creative possibilities, from a dash of colorful pattern in the entryway to the whimsy of a uniquely upholstered chair in the dining room or a luxuriously textured bedroom curtain. A practical primer on the many motifs available—“Nature”, “Animal”, “Floral”, “Ikat”, “Chinoiserie”, “Stripes”, and “Toile” are some of the chapters—this volume presents myriad versions of each, with inspiring examples of how to decorate with them. Salk also provides tips on how to use pattern in a particular space—for example, stripes create the illusion of a bigger room, and floral patterns look modern and bold (not fussy) when used on a big scale in bright colors. Presenting rooms by design stars such as Alessandra Branca, Miles Redd, Martyn Lawrence Bullard, and Mary McDonald, among others, The Power of Pattern teaches how to mix and match to make a house look effortlessly decorated. And Salk’s encouraging design tips give inspirational ideas and practical tips, opening up a world of decorating creativity.

Download or read book Radiation Pattern Reactive Power and Resistive Aperture Antennas written by Giorgio V. Borgiotti and published by . This book was released on 1975 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main purpose of the report is to establish certain structural properties of a peculiar class of Plane Wave Spectra (PWS) representing an aperture field (or, equivalently of radiation patterns) which make the aperture reactive power equal to zero. To achieve this objective the entire question of the representation of an aperture field through a PWS is reexamined from a novel viewpoint. The Fourier transform (FT) of the transverse electric field on the aperture is considered as a two-dimensional vector field on the wavenumber plane, represented through two scalar functions, which are its coordinates in a chosen vector basis (Section 3). The choice of the latter has an important physical significance since it corresponds to the decomposition of the PWS into two components having differently polarized radiation patterns and different reactive properties. In Section 4, it is shown that the conductance and the susceptance of an aperture can be expressed as integrals (extended over the visible and invisible space) of two quadratic forms (whose explicit expressions depend upon the basis chosen to represent the PWS).

Download or read book Taylor s Power Law written by R.A.J. Taylor and published by Academic Press. This book was released on 2019-06-20 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: Taylor's Power Law: Order and Pattern in Nature is a broad synthesis of this ubiquitous property of natural and man-made phenomena. This stimulating and approachable work surveys the biological and non-biological empirical data, describes the statistical uses of Taylor’s power law (TPL) and its relationship to statistical distributions, exposes the mathematical connections to other power laws, covers the competing explanatory models; and develops an argument for TPL's genesis. Taylor’s power law relates the variability of a process or population to its average value. It was first described in relation to insect populations and then more broadly to other animal and plant populations. Subsequently it has been recognized in microbiology, genetics, economics, astronomy, physics, and computer science, and it is thought to be one of the few general laws in ecology where it is routinely used to describe the spatial and temporal distributions of populations. Biologists who know the law as Taylor's power law and physical scientists who know it as fluctuation scaling will be interested in the bigger picture on this fascinating subject. As the relationship between variance and mean is found in so wide a range of disciplines, it seems possible it is a deep property of number, not just a phenomenon in ecology as was thought originally. Although theories abound that purport to explain or predict TPL, none is entirely satisfactory either because it fails to be very predictive, or it does not account for all the available empirical data. To uncover such a property requires a synthesis across disciplines, an acute need that is approached by this exciting work. Provides a single reference describing the properties, scope, and limitations of Taylor’s power law Reports the empirical, analytical, and theoretical work without opinion and ends with a critique of the work in order to develop a synthesis Collects together thoughts and suggestions of the hundreds who have written and speculated about Taylor’s power law in order to review examples (and counter-examples), as well as examine the various models developed to account for it

Download or read book A Pattern Language written by Christopher Alexander and published by Oxford University Press. This book was released on 2018-09-20 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: You can use this book to design a house for yourself with your family; you can use it to work with your neighbors to improve your town and neighborhood; you can use it to design an office, or a workshop, or a public building. And you can use it to guide you in the actual process of construction. After a ten-year silence, Christopher Alexander and his colleagues at the Center for Environmental Structure are now publishing a major statement in the form of three books which will, in their words, "lay the basis for an entirely new approach to architecture, building and planning, which will we hope replace existing ideas and practices entirely." The three books are The Timeless Way of Building, The Oregon Experiment, and this book, A Pattern Language. At the core of these books is the idea that people should design for themselves their own houses, streets, and communities. This idea may be radical (it implies a radical transformation of the architectural profession) but it comes simply from the observation that most of the wonderful places of the world were not made by architects but by the people. At the core of the books, too, is the point that in designing their environments people always rely on certain "languages," which, like the languages we speak, allow them to articulate and communicate an infinite variety of designs within a forma system which gives them coherence. This book provides a language of this kind. It will enable a person to make a design for almost any kind of building, or any part of the built environment. "Patterns," the units of this language, are answers to design problems (How high should a window sill be? How many stories should a building have? How much space in a neighborhood should be devoted to grass and trees?). More than 250 of the patterns in this pattern language are given: each consists of a problem statement, a discussion of the problem with an illustration, and a solution. As the authors say in their introduction, many of the patterns are archetypal, so deeply rooted in the nature of things that it seemly likely that they will be a part of human nature, and human action, as much in five hundred years as they are today.

Download or read book Pattern Calculus written by Barry Jay and published by Springer Science & Business Media. This book was released on 2009-07-30 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over time, basic research tends to lead to specialization – increasingly narrow t- ics are addressed by increasingly focussed communities, publishing in increasingly con ned workshops and conferences, discussing increasingly incremental contri- tions. Already the community of programming languages is split into various s- communities addressing different aspects and paradigms (functional, imperative, relational, and object-oriented). Only a few people manage to maintain a broader view, and even fewer step back in order to gain an understanding about the basic principles, their interrelation, and their impact in a larger context. The pattern calculus is the result of a profound re-examination of a 50-year - velopment. It attempts to provide a unifying approach, bridging the gaps between different programming styles and paradigms according to a new slogan – compu- tion is pattern matching. It is the contribution of this book to systematically and elegantly present and evaluate the power of pattern matching as the guiding paradigm of programming. Patterns are dynamically generated, discovered, passed, applied, and automatically adapted, based on pattern matching and rewriting technology, which allows one to elegantly relate things as disparate as functions and data structures. Of course, pattern matching is not new. It underlies term rewriting – it is, for example, inc- porated in, typically functional, programming languages, like Standard ML – but it has never been pursued as the basis of a unifying framework for programming.
