Electromagnetic geophysical tomography: An electromagnetic tomographic method for subsurface imaging is described. It reconstructs the electrical conductivity and dielectric permittivity profiles of the medium under investigation from phase-shift measurements of the received signals. Ray-optic approximations are made so that the problem reduces to solving two linear systems of equations.....; Authors:Lopes;E.P.;Lopes;E.P.Publisher:Radar and Signal Processing;IEE Proceedings FConference Date:ISSN:0956-375XTotal Page:

Supervised robotics for space servicing: Supervised robotics is the key to success for in-space servicing or other remote servicing operations. Advanced techniques include human-assisted vision processing, automatic calibration and retargeting, and advanced force compliant control macros. A combination of these techniques was developed and assembled in a laboratory experiment, demonstrati....; Authors:Kan;E.P.Publisher:Intelligent Robots and Systems '90.

Distributed transaction processing in the TUXEDO system: The TUXEDO system, a commercially proven transaction monitor, built on open industry standards, is described. It ensures data integrity in a distributed, heterogeneous environment with an optimized two-phase commit protocol. It offers an advanced client/server programming paradigm, increased throughput, network connectivity, and runtime system moni....; Authors:Felt;E.P.Publisher:Parallel and Distributed Information Systems;1993.;Proceedings of the Second International Conference onConference Date:20-22 Jan. 1993ISSN:0-8186-3330-1Total Page:xiv+272

Autoassociative memory with 'inverted pyramid' logic networks: Probabilistic logic nodes (PLNs) arranged in pyramids can become autoassociative when a noise-training procedure is applied. The author describes the behavior of pyramidal PLNs when the recall procedure is inverted. Nodes estimate their most probable inputs and pass these values to precursor nodes. Empirical analysis of standard PLN pyramid network....; Authors:Fulcher;E.P.Publisher:Neural Networks;1991.;IJCNN-91-Seattle International Joint Conference onConference Date:8-14 July 1991ISSN:0-7803-0164-1Total Page:2 vol.

Automatic training of stochastic finite-state language models for speech understanding: The representation of language models through stochastic finite state networks offers several attractive features for speech recognition and understanding, including the ease of integration with the algorithms used for acoustic-phonetic decoding. However, the application to real-world problems is difficult because the network sizes grow very large,....; Authors:Giachin;E.P.Publisher:Acoustics;Speech;and Signal Processing;1992.

Frequency warping by dynamic programming: The author introduces dynamic frequency warping (DFW), an exact analog of dynamic time warping (DTW) in which two utterances are represented by matrices, spectrograms that have been sampled in both frequency (perhaps by a discrete Fourier transform) and time (perhaps every centisecond). DFW tests all the dilations in the frequency direction that ca....; Authors:Neuburg;E.P.Publisher:Acoustics;Speech;and Signal Processing;1988.

On estimating rate of change of pitch: Spectra formed from adjacent speech segments are likely to be similar particularly if the pitch is constant. If the pitch is going up, the peaks in the later spectrum will be farther apart; the second peak will be very like a stretched version of the first. An algorithm is given for estimating this stretch and converting it to rate of change of pit....; Authors:Neuburg;E.P.Publisher:Acoustics;Speech;and Signal Processing;1988.

Online statistical process control with NDE and computers: It is shown that, for statistical process control (SPC) using ultrasonic instruments for nondestructive evaluation (NDE) directly interfaced with a computer, a variable in every part can be measured at production line speeds and used in groups, typically of five, to generate points for control charts. The process control computer can then analyze t....; Authors:Papadakis;E.P.Publisher:Ultrasonics Symposium;1988. Proceedings.;IEEE 1988Conference Date:2-5 Oct. 1988ISSN:Total Page:2 vol. 1113

What the robot's hand should tell the robot's brain: feature detection in a biological neural network: Biological neural networks in the somatosensory system process haptic information from the hand when it grasps and manipulates objects. The author describes how tactile sensors in the skin detect surface features which are of functional importance to the organism and how this information is further transformed by the central nervous system. The par....; Authors:Gardner;E.P.Publisher:Neural Networks;1988.;IEEE International Conference onConference Date:24-27 July 1988ISSN:Total Page:2 vol. (699+651)

Design for a second-generation proton storage ring at LAMPF: A conceptual design is presented for a second-generation proton storage ring (PSR) complex at LAMPF (Los Alamos Meson Physics Facility). The facility would consist of two stacked racetrack-shaped machines that would deliver a 1.2-mA beam of 1.6-GeV protons at 48 Hz. The pulse length would be 1.75 mu s, which represents a time compression of 570. Be....; Authors:Colton;E.P.Publisher:Particle Accelerator Conference;1989.
