Gas Sensing using Terahertz Time-Domain Spectroscopy
(1998-01-15)A method for detection and identification of polar gases and gas mixtures based on the technique of terahertz time-domain spectroscopy is presented. This relatively new technology promises to be the first portable far-infared ... -
A General Hardware/Software Co-design Methodology for Embedded Signal Processing and Multimedia Workloads
(2006-11-01)This paper presents a hardware/software co-design methodology for partitioning real-time embedded multimedia applications between software programmable DSPs and hardware based FPGA coprocessors. By following a strict set ... -
General-purpose architectures for media processing and database workloads
(2000)Workloads on general-purpose computing systems have changed dramatically over the past few years, with greater emphasis on emerging compute-intensive applications such as media processing and databases. However, until ... -
Generalized Beamforming for MIMO Systems with Limited Transmitter Information
(2003-11-20)In this work, we investigate the outage performance of beamforming schemes in wireless systems equipped with multiple transmit and receive antennas. In particular, we analyze the outage performance of unit rank beamforming ... -
Generalized Digital Butterworth Filter Design
(1996-01-15)This paper presents a formula-based method for the design of IIR filters having more zeros than (nontrivial) poles. The filters are designed so that their square magnitude frequency responses are maximally-flat at <i>m</i> ... -
Generalized Digital Butterworth Filter Design
(1995-01-15)This paper presents a formula-based method for the design of IIR filters having more zeros than (nontrivial) poles. The filters are designed so that their square magnitude frequency responses are maximally-flat at <i>m</i> ... -
Generalized Joint Signal Representations and Optimum Detection
(1996-01-20)Generalized joint signal representations (JSRs) extend the scope of joint time-frequency representations (TFRs) to a richer class of nonstationary signals, but their use, just as in the case of TFRs, has been primarily ... -
Generalized likelihood ratio detection for fMRI using complex data
(1999-04-20)The majority of fMRI studies obtain functional information using statistical tests based on the magnitude image reconstructions. Recently, a complex correlation (CC) test was proposed based on teh complex image data in ... -
Generalized recovery algorithm for 3D super-resolution microscopy using rotating point spread functions
(2016)Super-resolution microscopy with phase masks is a promising technique for 3D imaging and tracking. Due to the complexity of the resultant point spread functions, generalized recovery algorithms are still missing. We introduce ... -
GENERALIZED REPLACEMENT IN ITERATIVE RESTORATION ALGORITHMS
(1983)A new formulation of an iterative restoration algorithm is presented in this dissertation for the solution of noisy, non-linear restoration problems. The constraints and distortions are assumed to be known and are modeled ... -
Generation of diffraction-free beams for applications in optical microlithography
(1997-03-01)A new concept based on a Fabry–Perot interferometer for the generation of nondiffracting Bessel beams is described and proposed for potential applications in microlithography such as the fabrication of small isolated ... -
Generation of nearly nondiffracting Bessel beams with a Fabry–Perot interferometer
(1997-11-01)A new concept for generating zero-order Bessel beams was studied theoretically. The spatial intensity distribution was calculated numerically using a wave optics model. Approximate analytical expressions were derived to ... -
Genomic Detection Using Sparsity-inspired Tools
(2011)Genome-based detection methods provide the most conclusive means for establishing the presence of microbial species. A prime example of their use is in the detection of bacterial species, many of which are naturally vital ... -
A Geometric Hidden Markov Tree Wavelet Model
(2003-08-01)In the last few years, it has become apparent that traditional wavelet-based image processing algorithms and models have significant shortcomings in their treatment of edge contours. The standard modeling paradigm exploits ... -
Geometric Methods for Wavelet-Based Image Compression
(2003-08-01)Natural images can be viewed as combinations of smooth regions, textures, and geometry. Wavelet-based image coders, such as the space-frequency quantization (SFQ) algorithm, provide reasonably efficient representations for ... -
Geometric Tools for Image Compression
(2002-11-01)Images typically contain strong geometric features, such as edges, that impose a structure on pixel values and wavelet coefficients. Modeling the joint coherent behavior of wavelet coefficients is difficult, and standard ...
