Performing Beauty in Participatory Art and Culture (Routledge Advances in Art and Visual Studies)
by Falk HeinrichThis book investigates the notion of beauty in participatory art, an interdisciplinary form that necessitates the audience’s agential participation and that is often seen in interactive art and technology-driven media installations. After considering established theories of beauty, for example, Plato, Alison, Hume, Kant, Gadamer and Santayana through to McMahon and Sartwell, Heinrich argues that the experience of beauty in participatory art demands a revised notion of beauty; a conception that accounts for the performative and ludic turn within various art forms and which is, in a broader sense, a notion of beauty suited to a participatory and technology-saturated culture. Through case studies of participatory art, he provides an art-theoretical approach to the concept of performative beauty; an approach that is then applied to the wider context of media and design artefacts.

Performing Image (The\mit Press Ser.)
by Isobel HarbisonAn examination of how artists have combined performance and moving image for decades, anticipating our changing relation to images in the internet era.In Performing Image, Isobel Harbison examines how artists have combined performance and moving image in their work since the 1960s, and how this work anticipates our changing relations to images since the advent of smart phones and the spread of online prosumerism. Over this period, artists have used a variety of DIY modes of self-imaging and circulation—from home video to social media—suggesting how and why Western subjects might seek alternative platforms for self-expression and self-representation. In the course of her argument, Harbison offers close analyses of works by such artists as Robert Rauschenberg, Yvonne Rainer, Mark Leckey, Wu Tsang, and Martine Syms.Harbison argues that while we produce images, images also produce us—those that we take and share, those that we see and assimilate through mass media and social media, those that we encounter in museums and galleries. Although all the artists she examines express their relation to images uniquely, they also offer a vantage point on today's productive-consumptive image circuits in which billions of us are caught. This unregulated, all-encompassing image performativity, Harbison writes, puts us to work, for free, in the service of global corporate expansion. Harbison offers a three-part interpretive framework for understanding this new proximity to images as it is negotiated by these artworks, a detailed outline of a set of connected practices—and a declaration of the value of art in an economy of attention and a crisis of representation.

Peridynamics and Its Applications Using Ansys
by Yanan Zhang Erdogan Madenci Sundaram Vinod AnicodeThis book introduces a unified implementation of bond- and state-based peridynamic theory (PD) within a commercial finite element framework, Ansys, utilizing its native elements. It details the implementation of the PD theory and its integration with traditional finite elements. The primary objective is to equip students, researchers, and practicing engineers with both theoretical and practical knowledge of the PD theory, along with the skills necessary for analyzing engineering problems using Ansys. The book demonstrates that, unlike the conventional finite element method (FEM), the PD theory is highly suitable for progressive failure analysis, the multi-scale analysis of materials involving fracture and failure, and multi-physics analysis, including electromigration, corrosion, and electrodeposition. Additionally, it provides a step-by-step illustration of the specific procedures in the pre-processing, solution, and post-processing phases of the analysis through the Graphical User Interface (GUI) for various applications. The book is designed to be introductory and self-contained, minimizing the need for additional reference material.

Periodic Pattern Mining: Theory, Algorithms, and Applications
by Jerry Chun-Wei Lin Anirban Mondal Philippe Fournier-Viger R. Uday Kiran Jose M. LunaThis book provides an introduction to the field of periodic pattern mining, reviews state-of-the-art techniques, discusses recent advances, and reviews open-source software. Periodic pattern mining is a popular and emerging research area in the field of data mining. It involves discovering all regularly occurring patterns in temporal databases. One of the major applications of periodic pattern mining is the analysis of customer transaction databases to discover sets of items that have been regularly purchased by customers. Discovering such patterns has several implications for understanding the behavior of customers. Since the first work on periodic pattern mining, numerous studies have been published and great advances have been made in this field. The book consists of three main parts: introduction, algorithms, and applications. The first chapter is an introduction to pattern mining and periodic pattern mining. The concepts of periodicity, periodic support, search space exploration techniques, and pruning strategies are discussed. The main types of algorithms are also presented such as periodic-frequent pattern growth, partial periodic pattern-growth, and periodic high-utility itemset mining algorithm. Challenges and research opportunities are reviewed.The chapters that follow present state-of-the-art techniques for discovering periodic patterns in (1) transactional databases, (2) temporal databases, (3) quantitative temporal databases, and (4) big data. Then, the theory on concise representations of periodic patterns is presented, as well as hiding sensitive information using privacy-preserving data mining techniques.The book concludes with several applications of periodic pattern mining, including applications in air pollution data analytics, accident data analytics, and traffic congestion analytics.
Periodic Review Inventory Systems
by Thomas WensingThe focus of the work is twofold. First, it provides an introduction into fundamental structural and behavioral aspects of periodic review inventory systems. Second, it includes a comprehensive study on analytical and optimization aspects of a specific class of those systems. For the latter purpose, general solution methods for problems of inventory management in discrete time are described and developed along with highly specialized methods to solve very specific problems related to the model variants examined. The work is thus addressed to students and practitioners who seek a deeper understanding of managing inventories in discrete time as well as to software developers who require implementation aids on specific problems of inventory management.
Peripheral Interaction
by Saskia Bakker Doris Hausen Ted SelkerComputing devices havebecome ever more present in our everyday environments, however embedding thesetechnologies into our routines has remained a challenge. This book exploresthe novel theory of peripheral interaction to rectify this. This theory examines how interactivesystems canbe developed in such a way to allow people to seamlessly interact withtheir computer devices, but only focus on them at relevant times, building onthe way in which people effortlessly divide their attention over severaleveryday activities in day to day life. Capturing the currentstate of the art within the field, this book explores the history and foundationaltheories of peripheral interaction, discussesnovel interactive styles suitable for peripheral interaction, addressesdifferent application domains which can benefit from peripheral interaction andpresents visions of how thesedevelopments can have a positive impact on our future lives. As such, thisbook's aim is to contribute to research and practice in fields such ashuman-computer interaction, ubiquitous computing and Internet of Things, a viewon how interactive technology could be redesigned to form a meaningful, yetunobtrusive part of people's everyday lives. Peripheral Interaction will be highly beneficial to researchers anddesigners alike in areas such as HCI, Ergonomics and Interaction Design.
Peripheral Vision
by Zabet PattersonIn 1959, the electronics manufacturer Stromberg-Carlson produced the S-C 4020, a device that allowed mainframe computers to present and preserve images. In the mainframe era, the output of text and image was quite literally peripheral; the S-C 4020 -- a strange and elaborate apparatus, with a cathode ray screen, a tape deck, a buffer unit, a film camera, and a photo-paper camera -- produced most of the computer graphics of the late 1950s and early 1960s. At Bell Laboratories in Murray Hill, New Jersey, the S-C 4020 became a crucial part of ongoing encounters among art, science, and technology. In this book, Zabet Patterson examines the extraordinary uses to which the Bell Labs SC-2040 was put between 1961 and 1972, exploring a series of early computer art projects shaped by the special computational affordances of the S-C 4020. The S-C 4020 produced tabular data, graph plotting and design drawings, grid projections, and drawings of axes and vectors; it made previously impossible visualizations possible. Among the works Patterson describes are E. E. Zajac's short film of an orbiting satellite, which drew on the machine's graphic capacities as well as the mainframe's calculations; a groundbreaking exhibit of "computer generated pictures" by Béla Julesz and Michael Noll, two scientists interested in visualization; animations by Kenneth Knowlton and the Bell Labs artist-in-residence Stan VanDerBeek; and Lillian Schwartz's "cybernetic" film Pixillation.Arguing for the centrality of a peripheral, Patterson makes a case for considering computational systems not simply as machines but in their cultural and historical context.

Perl Best Practices: Standards and Styles for Developing Maintainable Code
by Damian ConwayMany programmers code by instinct, relying on convenient habits or a "style" they picked up early on. They aren't conscious of all the choices they make, like how they format their source, the names they use for variables, or the kinds of loops they use. They're focused entirely on problems they're solving, solutions they're creating, and algorithms they're implementing. So they write code in the way that seems natural, that happens intuitively, and that feels good.But if you're serious about your profession, intuition isn't enough. Perl Best Practices author Damian Conway explains that rules, conventions, standards, and practices not only help programmers communicate and coordinate with one another, they also provide a reliable framework for thinking about problems, and a common language for expressing solutions. This is especially critical in Perl, because the language is designed to offer many ways to accomplish the same task, and consequently it supports many incompatible dialects.With a good dose of Aussie humor, Dr. Conway (familiar to many in the Perl community) offers 256 guidelines on the art of coding to help you write better Perl code--in fact, the best Perl code you possibly can. The guidelines cover code layout, naming conventions, choice of data and control structures, program decomposition, interface design and implementation, modularity, object orientation, error handling, testing, and debugging.They're designed to work together to produce code that is clear, robust, efficient, maintainable, and concise, but Dr. Conway doesn't pretend that this is the one true universal and unequivocal set of best practices. Instead, Perl Best Practices offers coherent and widely applicable suggestions based on real-world experience of how code is actually written, rather than on someone's ivory-tower theories on howsoftware ought to be created.Most of all, Perl Best Practices offers guidelines that actually work, and that many developers around the world are already using. Much like Perl itself, these guidelines are about helping you to get your job done, without getting in the way.Praise for Perl Best Practices from Perl community members:"As a manager of a large Perl project, I'd ensure that every member of my team has a copy of Perl Best Practices on their desk, and use it as the basis for an in-house style guide."-- Randal Schwartz"There are no more excuses for writing bad Perl programs. All levels of Perl programmer will be more productive after reading this book."-- Peter Scott"Perl Best Practices will be the next big important book in the evolution of Perl. The ideas and practices Damian lays down will help bring Perl out from under the embarrassing heading of "scripting languages". Many of us have known Perl is a real programming language, worthy of all the tasks normally delegated to Java and C++. With Perl Best Practices, Damian shows specifically how and why, so everyone else can see, too."-- Andy Lester"Damian's done what many thought impossible: show how to build large, maintainable Perl applications, while still letting Perl be the powerful, expressive language that programmers have loved for years."-- Bill Odom"Finally, a means to bring lasting order to the process and product of real Perl development teams."-- Andrew Sundstrom"Perl Best Practices provides a valuable education in how to write robust, maintainable Perl, and is a definitive citation source when coaching other programmers."-- Bennett Todd"I've been teaching Perl for years, and find the same question keeps being asked: Where can I find a reference for writing reusable, maintainable Perl code? Finally I have a decent answer."-- Paul Fenwick"At last a well researched, well thought-out, comprehensive guide to Perl style. Instead of each of us developing our own, we can learn good practices from one of Perl's most prolific and experienced authors. I recommend this book to anyone who prefers getting on with the job rath
