Average case completeness
(Elsevier, 1991-06)
We explain and advance Levin's theory of average case completeness. In particular, we exhibit examples of problems complete in the average case and prove a limitation on the power of deterministic reductions.
SCFS: A UNIX Filesystem for Smartcards
(Center for Information Technology Integration, 1998-12-03)
Smartcard software developers suffer from the lack of a standard communication framework between a workstation and a smartcard. To address this problem, we extended the UNIX filesystem to provide access to smartcard storage, ...
Measurement scheduling for recursive team estimation
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1996-06)
We consider a decentralized LQG measurement scheduling problem in which every measurement is costly, no communication between observers is permitted, and the observers' estimation errors are coupled quadratically. This ...
Long range, high resolution laser radar
(Elsevier, 1994-01-15)
A high energy, chirped pulse laser was used to demonstrate long range, high resolution radar. A broadband nanosecond chirped pulse propagated to a target, and upon compression sub-millimeter surface resolution was obtained. ...
A graph-theoretic optimal control problem for terminating discrete event processes
(Kluwer Academic Publishers; Springer Science+Business Media, 1992-11)
Most of the results to date in discrete event supervisory control assume a “zero-or-infinity” structure for the cost of controlling a discrete event system, in the sense that it costs nothing to disable controllable events ...
A high-performance microflowmeter with built-in self test
(Elsevier, 1993-03)
This paper reports the development of a high-performance readout scheme based on a switched-capacitor circuit and intended for use with an ultrasensitive microflowmeter. The microflow transducer improves significantly on ...
Spectral Analysis Using Regularized Non-Negative Least-Squares Estimation
(IEEE, 1995-10-21)
The implementation of spectral analysis techniques involves solving a highly underdetermined linear system equation and is prone to the effect of measurement noise. The authors propose to use a regularized non-negative ...
Low-temperature silicon wafer-to-wafer bonding using gold at eutectic temperature
(Elsevier, 1994-05)
Micromechanical smart sensor and actuator systems of high complexity become commercially viable when realized as a multi-wafer device in which the mechanical functions are distributed over different wafers and one of the ...
