Methods of Integrating Design and Cost Information to Achieve Enhanced Manufacturing Cost/Performance Trade-offs

In this paper we address problems which arise when large organizations attempt a tight integration of design and cost while developing complex products. Topics include the sources of cost and design data, the arrangement of the databases, and the interfaces required. We also discuss the management methods required to develop and implement Design/Cost Database Commonality

Feasibility of fuel switching in Boston

This report develops a simple physical model that predicts that the nighttime dispersion of S2 from the largest sources in Boston is different than the dispersion of S2 from small, low level sources. Diurnal variations in S02 levels measured in Boston over the last seven years are analyzed in the light of this theory. The comparison between theory and observation is favorable. A simple, unambiguous, criteria for defining a large source is developed. The results are used to predict the fraction of the time large sources could burn high sulfur fuels while still meeting the state standards for sulfur dioxide

Magnetohydrodynamic surface waves

This is an experimental and theoretical study of deep water gravity-like waves which are induced in a liquid metal by a changing magnetic field. The dominant feature of such waves is the emission of Alfven waves from the free surface. A linearized theory is derived and compared with experiments
