- Physics, Medicine
- Applied optics
- 15 May 1985

Optical implementation of content addressable associative memory based on the Hopfield model for neural networks and on the addition of nonlinear iterative feedback to a vector-matrix multiplier is… Expand

The Bifurcating Neuron Network 2: an analog associative memory

- Gee-Hyuk Lee, N. Farhat
- Medicine, Computer Science
- Neural Networks
- 2002

The Bifurcating Neuron (BN), a chaotic integrate-and-fire neuron, is a model of a neuron augmented by coherent modulation from its environment. The BN is mathematically equivalent to the sine-circle… Expand

Prospects for three‐dimensional projective and tomographic imaging radar networks

Results of a study demonstrating the feasibility of broadband and speckle-free projective imaging of a complex shaped scattering object in the 6-17 GHz range with centimeter resolution are presented.… Expand

Corticonics: the way to designing machines with brainlike intelligence

- N. Farhat
- Engineering, Computer Science
- SPIE Optics + Photonics
- 17 November 2000

Present day neural net and connectionist models of the cortex have not been effective in duplicating higher-level brain function and specially the ability of the cortex/brain to process dynamic input… Expand

Self-Organization in a Parametrically Coupled Logistic Map Network: A Model for Information Processing in the Visual Cortex

- R. Pashaie, N. Farhat
- Computer Science, Medicine
- IEEE Transactions on Neural Networks
- 1 April 2009

In this paper, a new model seeking to emulate the way the visual cortex processes information and interacts with subcortical areas to produce higher level brain functions is described. We developed a… Expand

Millimeter wave holographic imaging of concealed weapons

Experiments are described in which optical images of small metallic objects were reconstructed from millimeter wave phasigrams (phase-only holograms). Since the well-established term HOLOGRAM… Expand

GBOPCAD: a synthesis tool for high-performance gain-boosted opamp design

- G. Yuan, N. Farhat, J. D. Spiegel
- Computer Science, Mathematics
- IEEE Transactions on Circuits and Systems I…
- 15 August 2005

A systematic design methodology for high-performance gain-boosted opamps (GBOs) is presented. The methodology allows the optimization of the GBO in terms of ac response and settling performance and… Expand

A low-cost millimeter-wave glow-discharge detector

- N. Farhat, N. S. Kopeika
- Physics
- 1 June 1972

A low-cost millimeter-wave glow-discharge detector characterized by a responsibility of 0.177 V/W, a rise time of 2.5 µs, and a noise equivalent power (NEP) of ∼10-13W/Hz when used in a synchronous… Expand

A new iterative algorithm for extrapolation of data available in multiple restricted regions with application to radar imaging

A new iterative method for extrapolation of incomplete segmented data available in multiple separated bands is proposed and tested. The method uses the Burg algorithm to find the linear prediction… Expand

Parametrically Coupled sine Map Networks

- Gee-Hyuk Lee, N. Farhat
- Mathematics, Computer Science
- Int. J. Bifurc. Chaos
- 1 July 2001

Due to an inversion symmetry and a bimodal nature, the sine map, defined in R, exhibits bistability which is subject to an attractor-merging crisis. Such dynamical characteristics of the sine map… Expand
