A future dynamically reconfigurable automotive software system

Embedded software systems in vehicles are of rapidly increasing commercial importance for the automotive industry. Current systems employ a static run-time environment; due to the difficulty and cost involved in the development of dynamic systems in a high-integrity embedded control context. A dynamic system, referring to the system configuration, would greatly increase the flexibility of the offered functionality and enable customised software configuration for individual vehicles, adding customer value through plug-and-play capability, and increased quality due to its inherent ability to adjust to changes in hardware and software. We envisage an automotive system containing a variety of components, from a multitude of organizations, not necessarily known at development time. The system dynamically adapts its configuration to suit the run-time system constraints. This paper presents our vision for future automotive control systems that will be regarded in an EU research project, referred to as DySCAS (Dynamically Self-Configuring Automotive Systems). We propose a self-configuring vehicular control system architecture, with capabilities that include automatic discovery and inclusion of new devices, self-optimisation to best-use the processing, storage and communication resources available, self-diagnostics and ultimately self-healing. Such an architecture has benefits extending to reduced development and maintenance costs, improved passenger safety and comfort, and flexible owner customisation. Specifically, this paper addresses the following issues: The state of the art of embedded software systems in vehicles, emphasising the current limitations arising from fixed run-time configurations; and the benefits and challenges of dynamic configuration, giving rise to opportunities for self-healing, self-optimisation, and the automatic inclusion of users’ Consumer Electronic (CE) devices. Our proposal for a dynamically reconfigurable automotive software system platform is outlined and a typical use-case is presented as an example to exemplify the benefits of the envisioned dynamic capabilities.

Projecting the prison: the depiction of the uncanny in The Shawshank Redemption

The space of the prison is no longer on the margins in relation to societal `centres', but instead acts as an adjunct to the urban environment. With the disappearance of the Gothic prison from the archi-texture of contemporary cities, the meaning conveyed by its façade has lost much of its potency. It is now contemporary prison drama, as opposed to the physical façade, that represents the interface between the public and the prison. This article explores a dramatic representation of the prison (The Shawshank Redemption) through the lens of Freud's (1919/1955) notion of the uncanny and Bachelard's (1958/1994) poetics of domestic space. Incarceration, as depicted in film and television, reinforces the `place myths' of the prison (Shields, 1991). Contemporary prison drama portrays the prison as a marginal space in much the way that the Gothic façades of the 19th-century prison projected a particular message. The prison, as depicted on screen, is a simulacrum. It is a facsimile of an architectural idea that only ever existed as a façade - a façade that occluded as much as it projected.
