In this paper, we consider the problem of approximately answering general aggregate SQL queries over continuous data streams with limited memory.

In this paper, we consider the problem of approximately answering aggregate SQL queries over continuous data streams with limited memory.

There is a growing interest in on-line algorithms for analyzing and querying data streams, that examine each stream element only once and have at their disposal, only a limited amount of memory.

In this paper, we present the skimmed-sketch-algorithm for estimating the join size of two streams.

We report theoretical calculations and experimental verification of an increase in memory SEU tolerance when Sandia's 2micron- technology 16K SRAMs are fabricated with ATT-BL's 1micron process.

Melt-textured-growth of polycrystalline YBa sub 2 Cu sub 3 O sub (7-delta) superconductor created a new microstructure which exhibited significantly improved transport J sub c values at 77K of ` 17

Analyzing and processing large graphs is of fundamental importance for an ever-growing number of applications.

Interest in GaAs Heterostructure FETs has increased significantly in recent years because of the potential benefits in circuit performance over conventional MESFET devices.

The science and technology of ferrite processing have been evolving, more like a step function, over the past thirty years.

Alternative to vapor deposition are being sought to provide less expensive processing of waveguides as well as new compositions and structures.
