Methods for scalable levels of parallelism in radix-2 ffts for fpga synthesis
(2014)
The Fast Fourier Transform (FFT) is the main block in many communication systems and signal processing applications, as it allows the fast computation of the discrete Fouier transform (DFT). The DFT, in turn, is used to ...
Computerized detection of semantic equivalence among sentences in natural language
(2011)
In natural language, different sentences can express the same meaning, or a sentence can be modified without altering its meaning. This is called “semantic equivalence”. Semantic equivalence can be resolved humans, but it ...
Unsupervised unmixing of hyperspectral imagery using the constrained positive matrix factorization
(2007)
In hyperspectral imaging, hundreds of images are taken at narrow and contiguous spectral bands providing us with high spectral resolution spectral signatures that can be used to discriminate between objects. In many ...
Object recognition using spherical harmonics shape descriptor in hyperspectral imagery
(2011)
Object recognition in hyperspectral and multispectral imagery has been studied in the last decade. The different approaches to recognition over hyperspectral images are based on spectral behavior, ignoring the shape behavior. ...
Nuevas estrategias para pronosticar la trayectoria e intensidad de los huracanes en el océano atlántico
(2007)
Durante muchos años, los científicos, matemáticos e ingenieros han estudiado sobre la formación de los huracanes. Dos aspectos muy importantes que los investigadores han tomado en consideración dentro del área de huracanes ...
A real-time manufacturing information exchange application between programmable logic controllers over a fault tolerant network
(2015)
This thesis presents the development of a test method for diagnosing the presence of embedded systems failures caused by physical defects in the printed circuit board and electronic components. Specifically, the proposed ...
Regularization in pattern reconigtion and hyperspectral data analysis
(2004)
New sensor technology provides higher spectral and spatial resolution enabling a greater number of spectrally separate classes to be identified. The Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) system, for ...
Tunable folded-slot antenna with thin film ferroelectric material Ferroelectric material
(2003)
In this work, the modeled performance of gold (Au)/ Ba0.60Sr0.40TiO3 (BSTO) ferroelectric/ magnesium oxide (MgO) two-layered tunable coplanar waveguide (CPW) fed folded–slot antenna (FSA) is presented. BSTO materials have ...
Development and analysis of the low torque generator for high efficiency applications
(2016-07)
This effort presents a novel design for a generator, named the low torque generator, as a device introduced for new applications. The main differences between the conventional generators and the low torque generator is the ...
On some algorithms for reverse engineering certain finite dynamical systems
(2005)
There are two general problems related to finite dynamical systems (FDS): the analysis and the synthesis (also known as the reverse engineering) problems. In the former, we are interested in uncovering the sequential ...
