Environmental Implications of Digital Technologies

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.
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.
This book is the second volume of proceedings of the 8th conference on "Finite Volumes for Complex Applications" (Lille, June 2017). It includes reviewed contributions reporting successful applications in the fields of fluid dynamics, computational geosciences, structural analysis, nuclear physics, semiconductor theory and other topics. The finite volume method in its various forms is a space discretization technique for partial differential equations based on the fundamental physical principle of conservation, and recent decades have brought significant advances in the theoretical understanding of the method. Many finite volume methods preserve further qualitative or asymptotic properties, including maximum principles, dissipativity, monotone decay of free energy, and asymptotic stability. Due to these properties, finite volume methods belong to the wider class of compatible discretization methods, which preserve qualitative properties of continuous problems at the discrete l evel. This structural approach to the discretization of partial differential equations becomes particularly important for multiphysics and multiscale applications. The book is useful for researchers, PhD and master’s level students in numerical analysis, scientific computing and related fields such as partial differential equations, as well as for engineers working in numerical modeling and simulations.
A total revision of the author’s previous work, Thermal Computations for Electronics: Conductive, Radiative, and Convective Air Cooling is a versatile reference that was carefully designed to help readers master mathematical calculation, prediction, and application methods for conductive, radiative, and convective heat transfer in electronic equipment. Presenting material in a way that is practical and useful to engineers and scientists, as well as engineering students, this book provides very detailed text examples and their solutions. This approach helps users at all levels of comprehension to strengthen their grasp of the subject and detect their own calculation errors. The beginning of this book is largely devoted to prediction of airflow and well-mixed air temperatures in systems and heat sinks, after which it explores convective heat transfer from heat sinks, circuit boards, and components. Applying a systematic presentation of information to enhance understanding and computational practice, this book: Provides complete mathematical derivations and supplements formulae with design plots Offers complete exercise solutions (MathcadTM worksheets and PDF images of Mathcad worksheets), lecture aids (landscape-formatted PDF files), and text-example Mathcad worksheets for professors adopting this book Addresses topics such as methods for multi-surface radiation exchange, conductive heat transfer in electronics, and finite element theory with a variational calculus method explained for heat conduction Presents mathematical descriptions of large thermal network problem formulation Discusses comprehensive thermal spreading resistance theory, and includes steady-state and time-dependent problems This reference is useful as a professional resource and also ideal for use in a complete course on the subject of electronics cooling, with its suggested course schedule and other helpful advice for instructors. Selected sections may be used as application examples in a traditional heat transfer course or to help professionals improve practical computational applications.

The public generally regards the media with suspicion and distrust. Therefore, the media's primary concern is to regain that trust through the production of sincerity. Advancing the field of media studies in a truly innovative way, Boris Groys focuses on the media's affect of sincerity and its manufacture of trust to appease skeptics. Groys identifies forms of media sincerity and its effect on politics, culture, society, and conceptions of the self. He relies on different philosophical writings thematizing the gaze of the other, from the theories of Heidegger, Sartre, Mauss, and Bataille to the poststructuralist formulations of Lacan and Derrida. He also considers media "states of exception" and their creation of effects of sincerity—a strategy that feeds the media's predilection for the extraordinary and the sensational, further fueling the public's suspicions. Emphasizing the media's production of emotion over the presentation (or lack thereof) of "facts," Groys launches a timely study boldly challenging the presumed authenticity of the media's worldview.
