Hertzian Tales: Electronic Products, Aesthetic Experience, and Critical Design

Anthony Dunne’s Hertzian Tales is an exploration of the aesthetic and conceptual aspects of industrial design and its potential to bring about social change for the users of electronic objects. It is a provoking and – to first-time readers – positively alarming social commentary on the interrelationship between electronic product design and culture, and the powerful but largely under-explored potential of electronic innovation to trigger social awareness. Hertzian Tales proposes an innovative approach to critical design and therefore serves as a reflection on and a critique of the commercial design practices at large. In this second edition, Dunne reiterates the original rationale for his project: a concern that the majority of industrial designers have unwittingly joined a treadmill culture of post-industrial mass-production – turning out electronic goods that have long simply met the brief of an optimally functioning and eagerly consumable technology.

Numerical treatment of a two-dimensional variable-order fractional nonlinear reaction-diffusion model

A two-dimensional variable-order fractional nonlinear reaction-diffusion model is considered. A second-order spatial accurate semi-implicit alternating direction method for a two-dimensional variable-order fractional nonlinear reaction-diffusion model is proposed. Stability and convergence of the semi-implicit alternating direct method are established. Finally, some numerical examples are given to support our theoretical analysis. These numerical techniques can be used to simulate a two-dimensional variable order fractional FitzHugh-Nagumo model in a rectangular domain. This type of model can be used to describe how electrical currents flow through the heart, controlling its contractions, and are used to ascertain the effects of certain drugs designed to treat arrhythmia.
