A neocortex-based model for pattern recognition
(2014)The information society needs to process massive volumes of data in automated ways. The data is more meaningful if it is considered as sequences of patterns rather than isolated patterns. A trained human brain has outstanding ... -
Neoliberalismo, sistema de mercado capitalista y política social durante la década de los 90's en Puerto Rico: vigencia y dimensión a considerar en el análisis crítico desde el trabajo social y la administración de los servicios sociales
(2024-05-14)Este trabajo presenta una revisión crítica sobre la relación e impacto del neoliberalismo y del sistema de mercado capitalista en las políticas del desarrollo, la política social y servicios sociales desde el trabajo social ... -
NESA neighborhood emergency support application
(2013)Weather inclement and natural disasters, such as hurricanes, tornados, earthquakes and fires, can affect communities adversely and people might suffer damages on their homes and goods. As a result, countless situations and ... -
Net-plankton diatoms of Puerto Rican water reservoirs as potential bioindicators of trophic status
(2014)Diatoms are a group of unicellular algae enclosed in a siliceous exoskeleton called the frustule. This ornamented structure allows for taxonomic identification. Diatoms are frequently used as indicators to monitor the ... -
A network simulator based on ospf routing protocol for network design and educational purposes
(2007)Computer simulation is the tool of choice for developing and testing new technologies and techniques. It is also commonly used to help teach and train students and other professionals. The Masters project done is a network ... -
A neural network approach to predict hurricane intensity in the North Atlantic basin
(2004)Upper air information and artificial neural networks (ANN) are used to predict hurricane intensity in the North Atlantic basin. Competitive neural network is used to identify analog storms to the current hurricane. Once ... -
A neural networks method to predict activity coefficients for binary systems based on molecular functional group contribution
(2006)Artificial neural network (ANN) techniques and functional group contributions were used to develop an algorithm to predict chemical activity coefficients. The ANN algorithm was trained using experimental ... -
A new approach to fight microorganisms: Termite-associated actinobacteria secondary metabolites against pathogenic bacteria and fungi
(2021-05-05)Las Actinobacterias son organismos Gram-positivos que tienen un alto contenido de GC en su genoma. Las bacterias de este filo son capaces de producir esporas y compuestos antimicrobianos. Además, estos microorganismos ... -
A new cloud classification system for rainfall detection over puerto rico using remotely sensed data
(2011)A new rainfall detection algorithm was developed to overcome challenges algorithms like the operational NOAA/NESDIS Hydro-Estimator (HE) present over Puerto Rico when detecting rainfall. The HE, a brightness temperature ... -
New constraints on crustal deformation within the Puerto Rico-Virgin Islands microplate using two decades of GPS data
(2019-05-14)Observations from Global Positioning System (GPS) along the northeastern region of the Caribbean Plate Boundary Zone have been used to evaluate crustal deformation in the Puerto Rico and Virgin Islands (PRVI) microplate ... -
New crystallographic structures of Oxy-HbII-III and CN-HbII-III forms from Lucina pectinata
(2011)The clam Lucina pectinata is found in the sulfide-rich southwest coastal sediments of La Parguera, Puerto Rico in the Caribbean Sea. This bivalve mollusk has developed a chemoautotrophic symbiotic relation with the bacteria ... -
The new face of the vampire: Autobiographical fiction in Anne Rice’s The Vampire Chronicles
(2007)This thesis studies how particular events in Anne Rice’s life have had impact in the context of her written work and how she as a writer manages to influence her works with these experiences from a twice-removed perspective. ... -
New families of 3D watermarks
(2020-07)In recent years researchers have developed families of 3D watermarks that are built by composition, using a base array and a periodic sequence of shifts. Multidimensional arrays that are constructed by composition of a ... -
New ferrocene chemotherapeutic drugs and early detection of breast cancer using a nanostructured gold biosensor
(2015)Three new ferrocene complexes were synthesized with 4-(1H-pyrrol-1-yl)phenol group appended to the cyclopentadienyl (Cp) rings. These are: 1,1’-4-(1H-pyrrol-1- yl)phenyl ferrocenedicarboxylate, (‘Fc-(CO2-Ph-4-Py)2’), ... -
New literacies: Using anime to expand teachers’ resources in the classroom
(2020-04-22)A continually changing environment of technology and communication in the modern workforce has established a new baseline for 21st-century students who require ESL educators to involve visual resources in their curriculum ... -
A new mixing rule in the modeling of the solubility of solids in supercritical fluids
(2006)Currently, supercritical-fluid technology in the pharmaceutical and microelectronics industries is increasingly applied to solve difficult processing problems. The solubility of a solute in the supercritical fluid is the ... -
A new multidimensional crystallographic fast fourier transform
(2004)The Fast Fourier Transform (FFT) describes a well known set of algorithms that allows a fast evaluation of the Discrete Fourier Transform (DFT). In FFTs, the original sequence is replaced by the sum of a shorter sequence ... -
A new preconditioner for solving linear systems with ill-conditioned Z-matrices
(2011-06)The class of Z-matrices is the set of matrices whose off-diagonal entries are non positive. Solving a linear system of the form Ax = b is possible if the coefficient matrix A has certain characteristics such as being of ... -
A new preconditions for solving linear systems with symmetric Z-matrices
