Interactive Query System for Reading Patterns in Time Series Data
Published Wednesday, September 26, 2001For tasks involving retrieval of information from large data sets, query formulation is a crucial step in the process. Insufficiently precise queries often lead to empty result sets (zero-hit queries') or large result sets with potentially irrelevant results. This problem is particularly troublesome in data mining applications where query...

High-Throughput Thin Film Fabrication Vacuum Flange
Published Thursday, September 20, 2001In high-throughput thin film experimentation, otherwise known as the combinatorial approach to thin film materials, a large number of samples with different compositions are fabricated together on an individual chip. Such chips/wafers/substrates are called combinatorial libraries. Alternatively, one may choose to make a sample where the...

PhotoMesa: A Zoomable Image Browser
Published Monday, September 17, 2001PhotoMesa is a zoomable image browser. It allows the user to view multiple directories of images in a zoomable environment, and uses a set of simple navigation mechanisms to move through the space of images. It also supports grouping of images by metadata available from the file system. It requires only a set of images on disk, and does not...

Treemap 3.0
Published Sunday, June 24, 2001Treemaps are a space-filling visualization for hierarchical structures that are extremely effective in showing attributes of leaf nodes by size and color coding. Treemaps enable users to compare sizes of nodes and of sub-trees and are especially strong in spotting unusual patterns.The Treemap visualization technique, developed by Ben...

Bistro: A System for Building Scalable Wide-Area Upload Applications
Published Wednesday, May 23, 2001Tremendous increases in network traffic are a major obstacle to achieving scalability in the Internet and other large networks. At the application layer, hot spots are usually caused by either (a) high demand for some data or (b) high demand for a certain service. Hot spots in download applications mostly result from a demand for popular data...

Power Control for Active Link Quality Protection in CDMA Networks
Published Monday, May 7, 2001Broadband CDMA systems will provide a wide range of multi-media services including voice, data and video. With multi-media traffic, users present the network with a range of bandwidth and quality of services (QoS) requirements.The performance of a CDMA system is interference limited. Interference can cause disruption in the service of...

Integrated Method for Performing Scheduling, Routing and Access Control in a Computer Network
Published Monday, May 7, 2001Computer networks based upon a series of nodes and servers interconnected by physical wiring have been well known for some time (e.g. Ethernet or Token-ring network). With the rapid development of the Internet, these computer networks must not only communicate effectively within their own domain or environment, but also must communicate between...

Power Control Based Admission Methods for Maximum Throughput in DS-CDMA Networks with Multi-Media Traffic
Published Monday, May 7, 2001There is an increasing use of multi-media transmissions over cellular CDMA networks. However, a CDMA cellular network is by its very nature interference limited. The layering of each signal across the available bandwidth increases the interference and affects the overall bandwidth utilization. Attempts have been made in the past to limit the...
