This implementation paper introduces principles for the informationarchitecture of an educational digital library, principles that address the distinction between designing digital libraries for education and designing digital libraries for information retrieval in general. Design is a key element of any successful product. Good designers and their(More)
An interface for software that creates a natural environment for engineering graphics students to improve their spatial reasoning and 3D visualization skills is described. The skills of interest involve spatial transformations and rotations, specifically those skills that engineers use to reason about 3D objects based on 2D representations. The software(More)
In equipment monitoring and diagnostics, it is very important to distinguish between a sensor failure and a system failure. In this paper, we develop a comprehensive methodology based on a hybrid system of AI and statistical techniques. The methodology is designed for monitoring complex equipment systems, which validates the sensor data, associates a degree(More)
Conceptual design requires processing information from diverse sources in order to define the functional requirements, operating constraints, and evaluation criteria pertinent to accomplishing a prescribed goal. This goal has traditionally been focused on the functionality of an artifact to be provided to a customer. Concurrent engineering redefines this(More)
An algorithm for automated construction of a sparse Bayesian network given an unstructured probabilis­ tic model and causal domain information from an expert has been developed and implemented. The goal is to obtain a network that explicitly reveals as much information regarding conditional indepen­ dence as possible. The network is built incrementally(More)
An emerging model in concurrent product design and manufacturing is the federation of workgroups across traditional functional " silos. " Along with the benefits of this concurrency comes the complexity of sharing and accessing design information. The primary challenge in sharing design information across functional workgroups lies in reducing the complex(More)
Energy efficient office lighting systems can save 40% in electricity consumption in areas that receive significant amounts of daylight. In spite of the savings they can generate, daylighting systems are not widely used in the commercial office building. Barriers prohibiting adoption include high retrofitting costs, and difficulty estimating and maintaining(More)
