Expected flood damage to buildings in riverine and coastal zones
(2007)
The methodologies used to estimate flood damage to buildings are typically based on aftermath surveys and statistical analyses of insurance claims data that do not consider the direct effects of floodwater hydrodynamics. ...
Magnetorheology in rotating magnetic fields
(2007)
We studied the flow of ferrofluid induced by rotating magnetic fileds. This flow was observed for first time in fi96F by Moskowitz and Rosensweig [App1. Ph4s. Gett., 10, pag. 3Ofi (fi96F)] and since then researchers has ...
Geometric scale-space framework for the analysis of hyperspectral imagery
(2007)
This work introduces a framework for a fast and algorithmically scalable multiscale representation and segmentation of hyperspectral imagery. The framework is based on the scale-space representation generated by geometric ...
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 ...
Métodos para mejorar la calidad de un conjunto de datos para descubrir conocimiento
(2007)
Today, data generation is growing exponentially in both directions; instances (rows) and features (columns). This causes that many datasets can not be analyzed without preprocessing. The large size of the dataset to be ...
High-level partitioning of discrete signal transforms for distributed hardware architectures
(2007)
Discrete signal transforms (DSTs) have numerous applications in a wide spectrum of scientific fields. To attain superior performance, the size and composition of these algorithms frequently require implementation to ...
On applications of rough sets theory to knowledge discovery
(2007)
Knowledge Discovery in Databases (KDD) is the nontrivial extraction of implicit, previously unknown and potentially useful information from data. Data preprocessing is a step of the KDD process that reduces the complexity ...
Studies of structural, electrical and ferroelectric properties of rare-earth substituted bismuth titanate-films.
(2007-05)
In the present research, Bi4Ti3O12 (BTO) and its rare earth (La, Nd, Sm, Gd)-substituted derivative thin films were synthesized using a sol-gel method and were systematically investigated. ...
