This thesis examines the evolution of Internet based knowledge networks (e-knowledge networks) in the domain of sustainable development. The objective of this thesis is to use an engineering systems approach to understand knowledge networks, identify the barriers to their sustainability…

This paper describes a natural language system START. The system analyzes English text and automatically transforms it into an appropriate representation, the knowledge base, which incorporates the information found in the text. The user gains access to information stored in…

Signature schemes are fundamental cryptographic primitives, useful as a stand-alone application, and as a building block in the design of secure protocols and other cryptographic objects. In this thesis, we study both the uses that signature schemes find in protocols,…

Public authorities and private developers around the world are attempting to create and sustain hubs within the innovation-based economy by fostering successful urban environments. These large-scale developments succeed an earlier generation of post-industrial "technopoles" named after the French word popularized…

Oligomeric mini-proteins, short peptides with protein-like features, constitute valuable minimal models for the study of oligomeric proteins. Oligomerization is a common feature of cellular proteins that may confer structural and functional advantages. Oligomerization is proposed to have arisen by several…

In plasma etching process it is critical to know when the film being etched has cleared to the underlying film, i.e. to detect endpoint, in order to achieve the desired device performance in the resulting integrated circuit. The most highly…

The state of business in the U.S. automobile industry is such that competition is fierce, and consumers have a perplexing number of alternatives from which to choose. The final purchase decision by the consumer is where most industry experts focus…

Intelligent autonomous agents working cooperatively accomplish tasks more efficiently than single agents, as well as tasks that were infeasible for the single agent. For example, a single agent transporting a ton of blocks will need to take multiple trips, possibly…
