The model estimates are then combined with subsystem cost data to gauge the cost-effectiveness …

Design Methodology Of Very Large Scale Integration, Ankush D. Oberai

Retrospective Theses and Dissertations

Very Large Scale Integration (VLSI) deals with systems complexity rather than transistor size or circuit performance. VLSI design methodology is supported by Computer Aided Design (CAD) and Design Automation (DA) tools, which help VLSI designers to implement more complex and guaranteed designs. The increasing growth in VLSI complexity dictates a hierarchical design approach and the need for hardware DA tools.

This paper discusses the generalized Design Procedure for CAD circuit design; the commercial CADs offered by CALMA and the Caesar System, supported by the Berkeley design tools. A complete design of a Content Addressable Memory (CAM) cell, using the Caesar …

Energy Storage Capacity Of Reversible Liquid‐Phase Diels Alder Reaction Between Maleic Anhydride And 2‐Methyl Furan, B. G. Sparks, Bruce E. Poling

Chemical and Biochemical Engineering Faculty Research & Creative Works

Calorimetry was used to determine the heat of reaction and equilibrium constant at 318 K for the reaction between maleic anhydride (A) and 2‐methyl furan (B). The values were −60 kJ/gmol and 614 cm3/gmol, respectively. The motivation for this work was to find a single phase‐reacting system that could be used to store solar energy. Thus, the energy storage capacity was calculated for a mixture of A and B, both initially at 7 kmol/m3, in dioxane. The maximum apparent heat capacity of 7.37 J/cm3·K occurred at 334 K. This maximum value is 76% higher than the heat capacity of pure …

Sandstone As A Construction Material Ky 80, Hazard To Watergap, Gary W. Sharpe, Herbert F. Southgate, David L. Allen, James H. Havens, Robert C. Deen

Kentucky Transportation Center Research Report

KY 80 (Hazard to Watergap) was constructed using abundantly available crushed sandstone. The pavements were designed to have adequate load-carrying capibilities and stability but were considered to be experimental (see Figure 1). It was intended that performance would be monitored and that undesirable features and performance would be identified and studied. Such surveillance was discontinued before construction was completed.

Recently, the need has arisen for testing and evaluation of some of the experimental sections. Some spalls, scuffs, and artesian water have been observed. Excessive water has appeared in the shoulder, median, and mainline. There has been at least one spot …
