A systematic approach to statistical simulation for large scale analog circuits is presented. The statistical model takes into account mismatch between devices due to variations in the process and noise, as well as interdie ...

We present a computational spectral factorization method to solve the optimal state feedback control problem for flexible structures with the following features: (1) Mathematically rigorous (2) Wide range of applicability ...

Decisions made during the design of a machined part can significantly affect the product's cost, quality, and lead time. Thus, in order to address the goals of concurrent engineering, it is important to evaluate the ...

In an approach recently proposed for the yield enhancement of programmable gate arrays (PGAs), an initial placement of a circuit is first obtained using a standard technique such as simulated annealing on a defect-free ...

For machining purposes, a part is often considered to be a feature-based model (FBM), i.e., a collection of machining features. However, often there can be several different FBM's of the same part. These models correspond ...

Vector Quantization has emerged as an efficient data compression tool for compressing speech and image data. We develop efficient systolic architecture implementations of Tree-Search Vector Quantizers (TSVQ) and Finite-State ...

Controlled experiments with novice treemap users and real data highlight the strength of treemaps and provide direction for improvement. Issues discussed include experimental results, layout algorithms, nesting offsets, ...

ESPRIT is a successful algorithm for determining the constant directions of arrival of a set of narrowband signals on an array of sensors. Unfortunately, its computational burden makes it unsuitable for real time processing ...

A major challenge addressed by conventional database systems has been to efficiently implement the transaction model, which provides the properties of atomicity, serializability, and permanence. Real-time applications have ...

As tolerance as a percent of feature size increases for sub- micron technologies with increased scaling, yield loses due to circuit performance fluctuations will increase. Therefore for sub-micron technologies a tradeoff ...
