A multiagent system approach for a self-reconfigurable electric power distribution system
(2006)
Electric power distribution systems (EPDS) can be found almost everywhere, from ship power systems to data centers. In many critical applications, it is necessary to maintain minimal operating capabilities under fault ...
Improving nonlinear dimensionality reduction algorithms for hyperspectral data
(2010)
Dimensionality reduction is a key step in hyperspectral image processing due to the large amount of data. Linear and nonlinear approaches have been proposed. The most important parameters on the majority of nonlinear ...
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 ...
An adaptive spectrally weighted structure tensor applied to tensor anisotropic nonlinear diffusion for hyperspectral images
(2012)
The structure tensor for vector valued images is most often defined as the average of the scalar structure tensors in each band. The problem with this definition is the assumption that all bands provide the same amount ...
Design of a reconfiguration controller for a dc zonal distribution system
(2005)
The use of DC Zonal System (DCZEDS) is evaluated as a potential simulation testbed for self-reconfigurable control research in electric power distribution systems. The DCZEDS is a SIMULINKTM implementation of a Ship DC ...
M-loc: real time location system for wireless mesh networks
(2008)
This thesis presents the design and implementation of a real time location system (RTLS) for wireless mesh networks. The system uses the received signal strength as the method of distance measurement. A prototype of this ...
Gray box modeling of electric drives using radial basis functions: an experimental case
(2006)
Modeling of electric drives coupled to complex mechanical loads may be a challenging task. Since the electric drives are commonly used in the industry, for many applications is desirable to have the capability of self-tuning ...
Evaluation of different structured models for target detection in hyperspectral imagery
(2010)
Target detection is an essential component in defense, security and medical applications of hyperspectral imagery. Structured and unstructured models are used to model variability of spectral signatures for the design of ...
A variable dimension gauss-newton method for ill- conditioned parameter estimation with application to a synchronous generator
(2005)
This thesis presents a variable dimension Gauss-Newton (VDGN) parameter estimation algorithm that can be used for fault detection, and diagnosis of a synchronous generator. The algorithm is derived as an extension of the ...
Multispectral image deblurring
(2007)
In this project, we implemented iterative algorithms for deblurring multispectral images. Deblurring was performed in a per channel basis. The algorithms were applied to LANDSAT-4 imagery of Puerto Rico. Deblurring methods ...
