Book Description
While digital media give us the ability to communicate with and know the world, their use comes at the expense of an immense ecological footprint and environmental degradation. In Finite Media Sean Cubitt offers a large-scale rethinking of theories of mediation by examining the environmental and human toll exacted by mining and the manufacture, use, and disposal of millions of phones, computers, and other devices. The way out is through an eco-political media aesthetics, in which people use media to shift their relationship to the environment and where public goods and spaces are available to all. Cubitt demonstrates this through case studies ranging from the 1906 film The Story of the Kelly Gang to an image of Saturn taken during NASA's Cassini-Huygens mission, suggesting that affective responses to images may generate a populist environmental politics that demands better ways of living and being. Only by reorienting our use of media, Cubitt contends, can we overcome the failures of political elites and the ravages of capital.

Collision Course

Author: Kerryn Higgs
Publisher: MIT Press
ISBN: 0262529696
Category : Science
Languages : en
Pages : 411

Book Description
The story behind the reckless promotion of economic growth despite its disastrous consequences for life on the planet. The notion of ever-expanding economic growth has been promoted so relentlessly that “growth” is now entrenched as the natural objective of collective human effort. The public has been convinced that growth is the natural solution to virtually all social problems—poverty, debt, unemployment, and even the environmental degradation caused by the determined pursuit of growth. Meanwhile, warnings by scientists that we live on a finite planet that cannot sustain infinite economic expansion are ignored or even scorned. In Collision Course, Kerryn Higgs examines how society's commitment to growth has marginalized scientific findings on the limits of growth, casting them as bogus predictions of imminent doom. Higgs tells how in 1972, The Limits to Growth—written by MIT researchers Donella Meadows, Dennis Meadows, Jorgen Randers, and William Behrens III—found that unimpeded economic growth was likely to collide with the realities of a finite planet within a century. Although the book's arguments received positive responses initially, before long the dominant narrative of growth as panacea took over. Higgs explores the resistance to ideas about limits, tracing the propagandizing of “free enterprise,” the elevation of growth as the central objective of policy makers, the celebration of “the magic of the market,” and the ever-widening influence of corporate-funded think tanks—a parallel academic universe dedicated to the dissemination of neoliberal principles and to the denial of health and environmental dangers from the effects of tobacco to global warming. More than forty years after The Limits to Growth, the idea that growth is essential continues to hold sway, despite the mounting evidence of its costs—climate destabilization, pollution, intensification of gross global inequalities, and depletion of the resources on which the modern economic edifice depends.

Finite-Element Modelling of Unbounded Media

ISBN:
Category : Mathematics
Languages : en
Pages : 360

Book Description
Dynamic unbounded medium-structure interactions occur in many fields of engineering and physical science, such as wave propagation in soil-structure and fluid-structure interactions, acoustics and electromagnetism and as diffusion in heat conduction and consolidation. This book presents three novel concepts, based on the finite-element methodology, to model the unbounded medium: The consistent infinitesimal finite-element cell method, a boundary finite-element procedure, requires the discretization of the structure-medium interface only and is exact in the finite-element sense. It is applied to unbounded media governed by the hyperbolic, parabolic and elliptic differential equations. The damping-solvent extraction method permits the analysis of a bounded medium only. The doubly-asymptotic multi-directional transmitting boundary is exact for the low- and high-frequency limits at preselected wave propagation directions. All concepts are explained using simple examples that the reader can follow step by step. A computer program of the consistent infinitesimal finite-element cell method available on disk analyses two- and three-dimensional unbounded and bounded media for the scalar and vector wave equations and the diffusion equation in the frequency and time domains.

FEFLOW

Author: Hans-Jörg G. Diersch
Publisher: Springer Science & Business Media
ISBN: 364238739X
Category : Science
Languages : en
Pages : 1018

Book Description
FEFLOW is an acronym of Finite Element subsurface FLOW simulation system and solves the governing flow, mass and heat transport equations in porous and fractured media by a multidimensional finite element method for complex geometric and parametric situations including variable fluid density, variable saturation, free surface(s), multispecies reaction kinetics, non-isothermal flow and multidiffusive effects. FEFLOW comprises theoretical work, modeling experiences and simulation practice from a period of about 40 years. In this light, the main objective of the present book is to share this achieved level of modeling with all required details of the physical and numerical background with the reader. The book is intended to put advanced theoretical and numerical methods into the hands of modeling practitioners and scientists. It starts with a more general theory for all relevant flow and transport phenomena on the basis of the continuum approach, systematically develops the basic framework for important classes of problems (e.g., multiphase/multispecies non-isothermal flow and transport phenomena, discrete features, aquifer-averaged equations, geothermal processes), introduces finite-element techniques for solving the basic balance equations, in detail discusses advanced numerical algorithms for the resulting nonlinear and linear problems and completes with a number of benchmarks, applications and exercises to illustrate the different types of problems and ways to tackle them successfully (e.g., flow and seepage problems, unsaturated-saturated flow, advective-diffusion transport, saltwater intrusion, geothermal and thermohaline flow).

Finite State Machine Datapath Design, Optimization, and Implementation

Author: Justin Davis
Publisher: Springer Nature
ISBN: 3031797760
Category : Technology & Engineering
Languages : en
Pages : 113

Book Description
Finite State Machine Datapath Design, Optimization, and Implementation explores the design space of combined FSM/Datapath implementations. The lecture starts by examining performance issues in digital systems such as clock skew and its effect on setup and hold time constraints, and the use of pipelining for increasing system clock frequency. This is followed by definitions for latency and throughput, with associated resource tradeoffs explored in detail through the use of dataflow graphs and scheduling tables applied to examples taken from digital signal processing applications. Also, design issues relating to functionality, interfacing, and performance for different types of memories commonly found in ASICs and FPGAs such as FIFOs, single-ports, and dual-ports are examined. Selected design examples are presented in implementation-neutral Verilog code and block diagrams, with associated design files available as downloads for both Altera Quartus and Xilinx Virtex FPGA platforms. A working knowledge of Verilog, logic synthesis, and basic digital design techniques is required. This lecture is suitable as a companion to the synthesis lecture titled Introduction to Logic Synthesis using Verilog HDL.

Frictionlessness

Author: Jakko Kemper
Publisher: Bloomsbury Publishing USA
ISBN:
Category : Technology & Engineering
Languages : en
Pages : 201

Book Description
Frictionlessness provides an examination of the environmentally destructive digital design philosophy of "frictionlessness" and the critical significance of a technological aesthetic of imperfection. If there is one thing that defines digital consumer technologies today, it is that they are designed to feel frictionless. From smart technologies to cloud computing, from from one-click shopping to the promise of seamless streaming-digital technology is framed to host ever-faster operations while receding increasingly into the background of perception. The environmental costs of this fetishization of frictionlessness are enormous and unevenly distributed; the frictionless experience of the end user tends to be supported by opaque networks of exploited labor and extracted resources that disproportionately impact the Global South. This situation marks an urgent need for alternate, less destructive aesthetic relations to technology. As such, this book examines imperfection, as an aesthetic concept that highlights existential conditions of finitude and fragility, as a particularly powerful counterweight to the dominant digital design philosophy of frictionlessness. While frictionlessness aims to draw the user's perception away from the exploitative and destructive conditions of digital production, imperfection forms an aesthetic source of friction that alerts users to the fragile nature of technology and the finite resources on which it relies. These arguments are elaborated through a close reading of three technological objects-a video game that was programmed to expire, an audiovisual performance that laments the fate of disused technology and a collection of music albums that dramatize a techno-cultural logic of relentless consumerism. Together, these case studies underline the value of technological aesthetics of imperfection and point to the need for a renewed ethics of care in relation to technology.

Publisher: Springer Science & Business Media
ISBN: 3540716971
Category : Mathematics
Languages : en
Pages : 330

Book Description
This book presents a mathematical structure modeling a physical or biological system that can be in any of a number of states. Each state is characterized by a set of binary features, and differs from some other neighbor state or states by just one of those features. The book considers the evolution of such a system over time and analyzes such a structure from algebraic and probabilistic (stochastic) standpoints.
