Selected AbstractsAn architecture for an intelligent support system for design validation and manufacturing of aerospace componentsINTERNATIONAL TRANSACTIONS IN OPERATIONAL RESEARCH, Issue 4 2003Costas Lambrinoudakis Abstract This paper presents the architecture of a multi-agent system that aims to support the design and manufacturing processes of composite material components for the aerospace, automobile, ship and other industries. The major goals are to accelerate the design process while minimising cost; support users in selecting the optimum material in terms of its properties, cost and environmental impact; and enhance the efficiency of the component manufacturing phase by extending the decision support capabilities of the existing real-time monitoring software. An important requirement for achieving these objectives is to enable the more efficient utilisation of existing distributed information on composite materials. To this end, state-of-the-art advances in metadata concepts were adopted and extended. By implementing metadata structures for each data category available, the searching and retrieval mechanisms are improved both in terms of speed and usage. In addition, large amounts of knowledge about the design and manufacturing processes themselves are incorporated into a multi-agent environment in order to enhance the ability to support the user groups involved in the various stages of component design and manufacturing. In order to present the system architecture here, an example from the aerospace industry has been used. [source] Evidence on the Incremental Information Contained in the Components of Restructuring ChargesJOURNAL OF BUSINESS FINANCE & ACCOUNTING, Issue 5-6 2002Thomas J. Lopez Among the new disclosures required by EITF 94,3 is the requirement that firms disclose the nature and amounts of the material components of a restructuring charge. The objective of this paper is to assess whether these components provide information to financial statement users beyond that contained in the aggregate charge. The evidence is consistent with the decomposition of the charge providing incremental information that would be lost if only the aggregate number is reported. The results also appear to suggest that analysts interpret restructurings as bad news and that inventory writedowns and employee terminations are interpreted as the most negative restructuring components. [source] The monolithic multicell: a tool for testing material components in dye-sensitized solar cellsPROGRESS IN PHOTOVOLTAICS: RESEARCH & APPLICATIONS, Issue 2 2007Henrik Pettersson Abstract A multicell is presented as a tool for testing material components in encapsulated dye-sensitized solar cells. The multicell is based on a four-layer monolithic cell structure and an industrial process technology. Each multicell plate includes 24 individual well-encapsulated cells. A sulfur lamp corrected to the solar spectrum has been used to characterize the cells. Efficiencies up to 6·8% at a light-intensity of 1000,W/msu2 (up to 7·5% at 250,W/m2) have been obtained with an electrolyte solution based on ,-butyrolactone. Additionally, a promising long-term stability at cell efficiencies close to 5% at 1000,W/m2 has been obtained with an electrolyte based on glutaronitrile. The reproducibility of the cell performance before and after exposure to accelerated testing has been high. This means that the multicell can be used as an efficient tool for comparative performance and stability tests. Copyright © 2006 John Wiley & Sons, Ltd. [source] | ||||||||||
