Automated Acquisition of Evolving Informal Descriptions
Reubenstein, Howard B.

Formato:
Enlaces:	The Listener is an automated system that unintrusively performs knowledge acquisition from informal input. The Listener develops a coherent internal representation of a description from an initial set of disorganized, imprecise, incomplete, ambiguous, and possibly inconsistent statements. The Listener can…

The Influence of Customer Scope on Supplier Learning and Performance in the Japanese Automobile Industry
Nobeoka, Kentaro - Dyer, Jeffrey

Formato:
Enlaces:	Most studies on Japanese supplier-automaker relationships have focused on the nature of the dyadic inter-firm relationship and the performance of the assembler. We examine the relationship between a Japanese supplier's "customer scope strategy" (i.e. number of customers) and the supplier's…

Internet Fish
LaMacchia, Brian A.

Formato:
Enlaces:	I have invented "Internet Fish," a novel class of resource-discovery tools designed to help users extract useful information from the Internet. Internet Fish (IFish) are semi-autonomous, persistent information brokers; users deploy individual IFish to gather and refine information related to…

A Circuit Grammar For Operational Amplifier Design
Ressler, Andrew Lewis

Formato:
Enlaces:	Electrical circuit designers seldom create really new topologies or use old ones in a novel way. Most designs are known combinations of common configurations tailored for the particular problem at hand. In this thesis I show that much of the…

Predicting the triple beta-spiral fold from primary sequence data
Scanlon, Eben Louis, 1974-

Formato:	Thesis
Enlaces:	The Triple β-Spiral is a novel protein structure that plays a role in viral attachment and pathogenesis. At present, there are two Triple β-Spiral structures with solved crystallographic coordinates - one from Adenovirus and the other from Reovirus. There is…

Dynamic power allocation and routing for satellite and wireless networks with time varying channels
Neely, Michael J. (Michael James), 1975-

Formato:	Thesis
Enlaces:	Satellite and wireless networks operate over time varying channels that depend on attenuation conditions, power allocation decisions, and inter-channel interference. In order to reliably integrate these systems into a high speed data network and meet the increasing demand for high…

Efficient on the fly maintenance of series-parallel relationships
Fineman, Jeremy T.

Formato:	Article
Enlaces:	A series-parallel directed acyclic graph, or SP-dag, contains nodes that are either in series or logically in parallel. We present a data structure and algorithm to efficiently determine, in a single serial walk of the dag, whether two nodes are…

Probabilistic risk analysis of restructured electric power systems : implications for reliability analysis and policies
Felder, Frank Andrew

Formato:	Thesis
Enlaces:	Modem society requires reliable and safe operation of its infrastructure. Policymakers believe that, in many industries, competitive markets and regulatory incentives will result in system performance superior to that under command-and-control regulation. Analytical techniques to evaluate the reliability and safety…

Cognitive and neural correlates of memory retrieval in young and older adults
O'Kane, Gail, 1965-

Formato:	Thesis
Enlaces:	(cont.) increased activity whenever recollection was attempted, independent of the level of recollection success. The results are consistent with the hypothesis that increased left-lateralized retrieval activity in older adults supports recollection attempt. Age deficits in semantic memory are more subtle…
