    Lex Informatica: The Formulation of Information Policy Rules through Technology

    Get PDF
    Historically, law and government regulation have established default rules for information policy, including constitutional rules on freedom of expression and statutory rights of ownership of information. This Article will show that for network environments and the Information Society, however, law and government regulation are not the only source of rule-making. Technological capabilities and system design choices impose rules on participants. The creation and implementation of information policy are embedded in network designs and standards as well as in system configurations. Even user preferences and technical choices create overarching, local default rules. This Article argues, in essence, that the set of rules for information flows imposed by technology and communication networks form a “Lex Informatica” that policymakers must understand, consciously recognize, and encourage

    Framework for the implementation of urban big screens in the public space

    In the last decade, big urban screens have appeared in town squares and on building facades across the UK. The use of these screens brings new potentials and challenges for city regulators, artists, architects, urban designers, producers, broadcasters and advertisers. Dynamic moving images form new architectural material, affecting our perception and the experience of the space around us. A new form of urban space is emerging that is fundamentally different from what we have known, and it seems that we are ill-equipped to deal with and analyse it. We are just beginning to understand the opportunities for public information, art and community engagement. Most of screens at present serve mainly commercial purposes, they do not broadcast information aimed at sharing community content nor do they support public social interactions. We need to see more negotiation between commercial, public and cultural interests. The SCREAM project addresses these new challenges by looking at the physical urban spaces and the potential spaces created by the new technologies

    Computational Contributions to the Automation of Agriculture

    The purpose of this paper is to explore ways that computational advancements have enabled the complete automation of agriculture from start to finish. With a major need for agricultural advancements because of food and water shortages, some farmers have begun creating their own solutions to these problems. Primarily explored in this paper, however, are current research topics in the automation of agriculture. Digital agriculture is surveyed, focusing on ways that data collection can be beneficial. Additionally, self-driving technology is explored with emphasis on farming applications. Machine vision technology is also detailed, with specific application to weed management and harvesting of crops. Finally, the effects of automating agriculture are briefly considered, including labor, the environment, and direct effects on farmers

    Data-driven through-life costing to support product lifecycle management solutions in innovative product development

    Get PDF
    Innovative product usually refers to product that comprises of creativity and new ideas. In the development of such a new product, there is often a lack of historical knowledge and data available to be used to perform cost estimation accurately. This is due to the fact that traditional cost estimation methods are used to predict costs only after a product model has been built, and not at an early design stage when there is little data and information available. In light of this, original equipment manufacturers are also facing critical challenges of becoming globally competitive and increasing demands from customer for continuous innovation. To alleviate these situations this research has identified a new approach to cost modelling with the inclusion of product lifecycle management solutions to address innovative product development.The aim of this paper, therefore, is to discuss methods of developing an extended-enterprise data-driven through-life cost estimating method for innovative product development

    How to choose and how to watch: an on-demand perspective on current TV practices

    In Sweden, digital TV services have until very recently not been accessible to most people through the TV set. At the same time, TV channels offer more and more content on the web and the majority of the population has access to high-speed internet connections. A web survey aimed at investigating attitudes and behavior related to on-demand TV was distributed in December 2008 to 52 households in an experimental, open (operator neutral) access network in Sweden. Questions were posed on TV arrangements, habits and attitudes; social aspects of TV watching; watching film or TV on-demand; and watching film or TV using the computer. Complementary interviews were also performed with participants that were not part of the experimental environment. Results show that participants in the studies understood and felt a need for time-shift and on-demand TV services: time-shift needs for re-scheduling, catch-up and repeats were expressed as well as on-demand needs for movies and for accessing otherwise unavailable TV content. Support for on-demand TV could also be found in that subjects reported little need for viewing TV content according to a broadcast schedule, with the main exception of news, sports events and other live broadcasts
