152 Horch, Kenneth W.Action potential classification with dual channel intrafascicular electrodesUsing recordings of peripheral nerve activity made with carbon fiber intrafascicular electrodes, we compared the performance of three different recording techniques (single channel, differential, and dual channel) and four different unit classification methods (linear discriminant analysis, temp...Carbon fiber intrafascicular electrodes; Dual channel recording1994
153 Sobh, Tarek M.Active inspection and reverse engineeringWe propose a new design for inspection and reverse engineering environments. In particular, we investigate the use of discrete event dynamic systems (DEDS) to guide and control the active exploration and sensing of mechanical parts for industrial inspection and reverse engineering. We introduce dyn...Discrete event dynamic systems; DEDS; Industrial inspection1993
154 Horch, Kenneth W.; Lawrence, Steve M.; Dhillon, Gurpreet S.Acute peripheral nerve recording characteristics of polymer-based longitudinal intrafascicular electrodesWe examined the recording characteristics of two different types of polymer-based longitudinal intrafascicular electrodes (LIFEs) in peripheral nerve: single-stranded (s-polyLIFEs) and multistranded (m-polyLIFEs). Recordings were also made from Pt-Ir wire-based electrodes (PtIrLIFEs) as a control. T...Sciatic Nerve; Intrafascicular Electrodes, Peripheral Nerve Recording2004
155 Organick, Elliott I.ADA to silicon transformations: the outline of a methodThis report explores the contention that a high-order language specification of a machine (such as an Ada program) can be methodically transformed into a hardware representation of that machine. One series of well-defined steps through which such transformations can take place is presented in this i...ADA program; High-order language specification1982
156 Carter, Tony M.Ada-to-silicon compiler study (Final Report 30 Jan 85 - 30 Jun 86)The vision of a system design environment in which both hardware and software components could be designed, tested, and executed was proffered by the late Dr. Elliott Organick1 in 1981. He was impressed by the objectiveness of Ada and the availability of an architecture (the Intel 432) which was sp...ADA language1986
157 Mathews, V.

Such models can approximate a large class of non-linear systems adequately, and usually with considerable parsimony in the number of coeff...1991
158 Mathews, V. JohnAdaptive bilinear predictorsThis paper considers an extended recursive least squares (RLS) adaptive bilinear predictor. It is shown that the extended RLS adaptive bilinear predictor is guaranteed to be stable in the sense that the time average of the squared a-posteriori prediction error signal is bounded whenever the input...1994
159 Mathews, V. JohnAdaptive filters requiring zero multiplicationsThis paper introduces an adaptive filter structure that requires zero multiplications for its implementations. The primary input signals are quantized using DPCM and the DPCM outputs are processed by the adaptive filter. The sign algorithm. We show that if the parameters are chosen properly, hardwar...1987
160 Mathews, V. John; Nilsson, MichaelAdaptive gain processing to improve feedback cancellation in digital hearing aidsAdaptive filters are commonly used to cancel acoustic feedback in hearing aids. The sound quality of hearing aids deteriorates as the hearing aid gain is increased.

161 Mathews, V. JohnAdaptive gain processing with offending frequency suppression for digital hearing aidsDigital hearing aids identify acoustic feedback signals and cancel them continuously in a closed loop with an adaptive filter. This scheme facilitates larger hearing aid gain and improves the output sound quality of hearing aids. However, the output sound quality deteriorates as the hearing aid gai...2012
