The Mesh


Book Description

A simple, powerful idea that's reinventing the way smart, adaptive companies do business. Most businesses follow the same basic formula: create a product or service, sell it, and collect money. What Lisa Gansky calls "Mesh" businesses throw this model out the window. Instead, these companies use social media, wireless networks, and data crunched from every available source to provide people with goods and services at the exact moment they need them, without the burden and expense of owning them outright. The Mesh gives companies a better understanding of what customers really want. Already, hundreds of successful Mesh companies are redefining how we interact with the people, goods, and services in our lives. These businesses are easier to start and spreading like wildfire, from bike sharing and home exchanges to peer-to-peer lending, energy cooperatives, and open source design. Consider: • ZipCar profits from streamlined car sharing • Kickstarter connects artists with funding from enthusiastic supporters • Music Gym makes finding a recording studio as easy as joining a gym The Mesh reveals the next wave of information-enabled commerce, showing readers how to plug in and profit.




Narrating the Mesh


Book Description

A hierarchical model of human societies’ relations with the natural world is at the root of today’s climate crisis; Narrating the Mesh contends that narrative form is instrumental in countering this ideology. Drawing inspiration from Timothy Morton’s concept of the "mesh" as a metaphor for the human-nonhuman relationship in the face of climate change, Marco Caracciolo investigates how narratives in genres such as the novel and the short story employ formal devices to effectively channel the entanglement of human communities and nonhuman phenomena. How can narrative undermine linearity in order to reject notions of unlimited technological progress and economic growth? What does it mean to say that nonhuman materials and processes—from contaminated landscapes to natural evolution—can become characters in stories? And, conversely, how can narrative trace the rising awareness of climate change in the thick of human characters’ mental activities? These are some of the questions Narrating the Mesh addresses by engaging with contemporary works by Ted Chiang, Emily St. John Mandel, Richard Powers, Jeff VanderMeer, Jeanette Winterson, and many others. Entering interdisciplinary debates on narrative and the Anthropocene, this book explores how stories can bridge the gap between scientific models of the climate and the human-scale world of everyday experience, powerfully illustrating the complexity of the ecological crisis at multiple levels.




Data Mesh


Book Description

Many enterprises are investing in a next-generation data lake, hoping to democratize data at scale to provide business insights and ultimately make automated intelligent decisions. In this practical book, author Zhamak Dehghani reveals that, despite the time, money, and effort poured into them, data warehouses and data lakes fail when applied at the scale and speed of today's organizations. A distributed data mesh is a better choice. Dehghani guides architects, technical leaders, and decision makers on their journey from monolithic big data architecture to a sociotechnical paradigm that draws from modern distributed architecture. A data mesh considers domains as a first-class concern, applies platform thinking to create self-serve data infrastructure, treats data as a product, and introduces a federated and computational model of data governance. This book shows you why and how. Examine the current data landscape from the perspective of business and organizational needs, environmental challenges, and existing architectures Analyze the landscape's underlying characteristics and failure modes Get a complete introduction to data mesh principles and its constituents Learn how to design a data mesh architecture Move beyond a monolithic data lake to a distributed data mesh.




Adaptive Moving Mesh Methods


Book Description

This book is about adaptive mesh generation and moving mesh methods for the numerical solution of time-dependent partial differential equations. It presents a general framework and theory for adaptive mesh generation and gives a comprehensive treatment of moving mesh methods and their basic components, along with their application for a number of nontrivial physical problems. Many explicit examples with computed figures illustrate the various methods and the effects of parameter choices for those methods. Graduate students, researchers and practitioners working in this area will benefit from this book.




Finite Element Mesh Generation


Book Description

Highlights the Progression of Meshing Technologies and Their Applications Finite Element Mesh Generation provides a concise and comprehensive guide to the application of finite element mesh generation over 2D domains, curved surfaces, and 3D space. Organised according to the geometry and dimension of the problem domains, it develops from the basic meshing algorithms to the most advanced schemes to deal with problems with specific requirements such as boundary conformity, adaptive and anisotropic elements, shape qualities, and mesh optimization. It sets out the fundamentals of popular techniques, including: Delaunay triangulation Advancing-front (ADF) approach Quadtree/Octree techniques Refinement and optimization-based strategies From the geometrical and the topological aspects and their associated operations and inter-relationships, each approach is vividly described and illustrated with examples. Beyond the algorithms, the book also explores the practice of using metric tensor and surface curvatures for generating anisotropic meshes on parametric space. It presents results from research including 3D anisotropic meshing, mesh generation over unbounded domains, meshing by means of intersection, re-meshing by Delaunay-ADF approach, mesh refinement and optimization, generation of hexahedral meshes, and large scale and parallel meshing, along with innovative unpublished meshing methods. The author provides illustrations of major meshing algorithms, pseudo codes, and programming codes in C++ or FORTRAN. Geared toward research centers, universities, and engineering companies, Finite Element Mesh Generation describes mesh generation methods and fundamental techniques, and also serves as a valuable reference for laymen and experts alike.

Geometry and Topology for Mesh Generation


Book Description

The book combines topics in mathematics (geometry and topology), computer science (algorithms), and engineering (mesh generation). The original motivation for these topics was the difficulty faced (both conceptually and in the technical execution) in any attempt to combine elements of combinatorial and of numerical algorithms. Mesh generation is a topic where a meaningful combination of these different approaches to problem solving is inevitable. The book develops methods from both areas that are amenable to combination, and explains recent breakthrough solutions to meshing that fit into this category.The book should be an ideal graduate text for courses on mesh generation. The specific material is selected giving preference to topics that are elementary, attractive, lend themselves to teaching, useful, and interesting.
