Equipment developed for the manufacture of over 100 kg of silicon ingot from one crucible by rechanging from another crucible is described. Attempts were made to eliminate the cost of raising the furnace temperature to 250 C above the melting point of silicon by using an RF coil to melt polycrystalline silicon rod as a means of rechanging the crucible. Microprocessor control of the straight growth process was developed and domonstrated for both 4 inch and 6 inch diameter. Both meltdown and melt stabilization processes were achieved using operat...

Abstract This paper presents the cost analyses required to ascertain the economic viability of HFC networks from the perspective of telephone service providers. The cost model for an HFC network delivering video is presented first in order for the installed first cost (IFC) for video to be computed. Using this HFC network as an infrastructure, the cost model for an HFC network with a telephone overlay is developed, and the incremental cost (IC) analysis for telephony is also presented

Abstract As we are catapulted into the maelstrom of 21st century server class teraflops, kilowatts, "1000 way" integration, Maturity at Birth TTM pounding, and screaming cost pressure - reliance on the rote, sequential, and evolutionary legacy processes to attain marketplace quality & reliability (Q&R) demands position test & reliability as the impediment to maintaining the industry's rate of advancement. Test and screens effectiveness erosion, insatiable customer expectations (reliability) and demands (function), perpetual revolutionary techn...
In the last two decades, a number of algorithms for the linear single-commodity Min Cost Flow problem (MCF) have been proposed, and several efficient codes are available that implement different variants of the algorithms. The practical significance of the algorithms has been tested by comparing the time required by their implementations for solving "from scratch" instances of (MCF), of different classes, as the size of the problem (number of nodes and arcs) increases. However, in many applications several closely related instances of (MCF) hav...
Abstract This paper develops an interruption cost model for households that, as well as outage duration uses activity patterns, outdoor temperature and daylight to describe the impact of different electrical power outages. For households the interruption costs usually measure the inconvenience associated with interrupted activities and uncomfortable indoor temperature due to the outage. Further, the model also captures the large variations in interruption costs for identical outages among households. The model is applied to a test system, and ...

Abstract The results of a one-year study to determine the impact of Ada on software costs, productivity, and quality are presented. A description is given of the statistical analysis and validation of the forty-one completed projects in the Ada costs database in the areas of cost, distribution of effort, error rates, productivity, and reuse potential. Also described are the development and validation of the mathematical model, the power laws formulated as a result of these activities, the development of the model into an automated cost-estimat...
