The effects of using a wind acceleration device (wind lens) with vertical-axis wind turbines in wind tunnel experiments were examined. A wind lens consists of a diffuser and flanges, and this study investigated the optimum parameters of their configuration with regard to the power augmentation of the turbines. The wind lens with a flat-panel-type diffuser demonstrated power augmentation by a fa...
Note: This essay was written for the catalog that accompanied the exhibition: Eigenwelt der Apparatewelt: Pioneers of Electronic Art. The exhibition was presented as part of Ars Electronica 1992, in Linz, Austria and was curated by Woody and Steina Vasulka. It consisted of a comprehensive, interactive display of vintage electronic tools for video and audio generation/processing from the 1960's ...
Today’s public displays effectively disappear: people have become so accustomed to their low utility that they ignore them. In contrast to Mark Weiser’s influential vision of the “Computer for the 21st Century,” however, public displays of the 21st century should not disappear. Instead they should become the backbone of a new global communications medium. The creation of this new communications...
The Survey of Labour and Income Dynamics (SLID) has been a source of longitudinal data since 1993. Respondents are surveyed twice a year—once on labour and once on income—for six consecutive years. Each six-year period is called a panel, and new panels are begun every three years. Presently, longitudinal data are available from two complete panels, 1993 to 1998 and 1996 to 2001, which have been...
We present a dictator game experiment where the recipients are local charities that serve the poor. Donors consist of approximately 1000 participants from a nationally representative respondent panel that is maintained by a private survey research firm, Knowledge Networks. We randomly manipulate the perceived race and worthiness of the charity recipients by showing respondents an audiovisual pr...
This paper presents and discusses several methods for reasoning from inconsistent knowledge bases. A so-called argumentative-consequence relation, taking into account the existence of consistent arguments in favor of a conclusion and the absence of consistent arguments in favor of its contrary, is particularly investigated. Flat knowledge bases, i.e. without any priority between their elements,...
A purpose of this study is to examine how a firm without fundamental technology is able to gain the competitive advantage. This paper examines three case studies, Sony in the flat display TV industry, Casio in the digital camera industry and Nintendo in the home game machine industry. This paper maintain the firms without fundamental technology construct two advantages, economic advantage and o...
The sequence of source and detector positions in a CT scan determines reconstructable volume and data completeness. Commonly this is regarded already in the design phase of a scanner. Modern flatpanel scanners, however, allow to acquire a broad range of positions. This enables many possibilities for different scan paths. However, every new path or trajectory implies different data completeness....
