Fabrication of plasmonic nanoparticle structures on planar substrates
(2006)Studying the optical properties of coupled plasmonic systems is important for both fundamental understanding and optimization of plasmonenhanced optical sensing applications such as surface enhanced Raman scattering (SERS), ... 
Failure Mode Analysis of a Proposed Manipulatorbased Hazardous Material Retrieval System
(19970401)Failure mode and reliability analysis is particularly important for robot manipulators to be deployed in remote environments, where inspection and repair are diffcult, and reliability is of prime importance. This is ... 
FARINFRARED PHOTOCONDUCTIVITY IN HIGH PURITY EPITAXIAL INDIUMPHOSPHIDE
(1981)Farinfrared photoconductivity from shallow donors in ntype InP was studied using Fourier transform spectroscopy. The 1s to 2p transition frequency was found to be 45.5 (+OR) 0.2 cm('1) in zero magnetic field. Spectral ... 
Fast computation of the slidingwindow Radon transform with application to attribute extraction
(19990115)We have developed a fast and robust algorithm for the extraction of 3D seismic attributes. The algorithm is based on the recursive computation of the 3D slidingwindow Radon transform. Considerable gain in computational ... 
Fast Fourier transforms for constrained data
(1988)This thesis develops several new algorithms for computing the discrete Fourier transform (DFT). The work describes algorithms for which a set of constraints on the input or the output allow the DFT to be computed more ... 
Fast, Exact Synthesis of Gaussian and nonGaussian LongRangeDependent Processes
(19990115)1/<i>f</i> noise and statistically selfsimilar processes such as fractional Brownian motion (fBm) are vital for modeling numerous realworld phenomena, from network traffic to DNA to the stock market. Although several ... 
FaultTolerant VLSI Processor Array for the SVD
(19891001)Dynamic reconfiguration techniques are presented for a twodimensional systolic array for the SVD of a matrix. Extra computation time is not required, since idle time inherent in the array is exploited. The scheme does not ... 
Feature Extraction Techniques for Classification and Identification of Spectral Signatures
(19760420)Some of the results obtained at Rice University on the extraction of features from spectral signatures for the purpose of classifying and identifying these signatures are described. 
Feedback gain in Multiple Antenna Systems
(20020520)Multiple antenna transmission and reception have been shown to significantly increase the achievable data rates of wireless systems. However, most of the existing analysis assumes perfect or no channel information at the ... 
FFTAccelerated Iterative MIMO Chip Equalizer Architecture For CDMA Downlink
(20050301)In this paper, we present a novel FFTaccelerated iterative Linear MMSE chip equalizer in the MIMO CDMA downlink receiver. The reversed form timedomain matrix multiplication in the Conjugate Gradient iteration is accelerated ... 
Finite Rate Feedback Design for Multiple Transmit Antennas
(20021020)Many practical systems employ a feedback channel to convey the channel state information to the transmitter.The capacity of the feedback channels is usually limited to a few bits per frame. We design feedback based ... 
Flexible NWay MIMO Detector on GPU
(20121017)This paper proposes a flexible MultipleInput MultipleOutput (MIMO) detector on graphics processing units (GPU). MIMO detection is a key technology in broadband wireless system such as LTE,WiMAX, and 802.11n. Existing ... 
Flexible Wavelet Transforms Using Lifting
(19980901)We introduce and discuss biorthogonal wavelet transforms using the lifting construction. The lifting construction exploits a spatialdomain, predictionerror interpretation of the wavelet transform and provides a powerful ... 
FloatingPoint CORDIC for Matrix Computations
(19881001)The CORDIC algorithms provide a VLSI hardware technique for computing the inverse tangents and vector rotations needed by many matrix decomposition algorithms. Although normally stated for fixedpoint arithmetic, the CORDIC ... 
Focused terahertz waves generated by a phase velocity gradient in a parallelplate waveguide
(2015)We demonstrate the focusing of a freespace THz beam emerging from a leaky parallelplate waveguide (PPWG). Focusing is accomplished by grading the launch angle of the leaky wave using a PPWG with gradient plate separation. ... 
Four top reasons why mutual information does not assess neural information processing
(20020720)Mutual information between stimulus and response has been advocated as an information theoretic measure of a neural system's capability to process information. Once calculated, the result is a single number that supposedly ...
