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 ...
Characterization of asymmetric annular-slot antennas and design of a tunable asymmetric annular-slot antenna with ferroelectric material
(2006)
A statistical characterization of an annular slot ring antenna using DOE is presented. The models give an understanding on the effects of the antenna design parameters on the responses of the antenna. These models are ...
Moisture effects on short term durability and mechanical properties of two Puerto Rico crushed limestone aggregates
(2009-12)
This Master of Science thesis includes an experimental characterization of the mechanical properties of two Puerto Rico crushed limestone aggregates (CLA). Specifically, the crushed limestone was obtained from two quarries ...
Purification and characterization of trypsin from intestinal and pyloric caecal tissues from the silk snapper, Lutjanus vivanus (Cuvier, 1828)
(2003)
In an effort to better understand the chemical digestion of proteins in the silk
snapper, Lutjanus vivanus (Cuvier, 1828), and thereby obtain a deeper understanding of
how this fish meets its dietary needs for amino acids ...
Análisis y reconstrucción del decaimiento hadrónico j J/ψ→ K+K−π+π−π0
(2009)
Se determinó la razón de producción para el decaimiento hadrónico J/ψ→ K+K−π+π−π0 y se realizó una comparación con los valores obtenidos en un análisis previo basado en una muestra de 3 millones de eventos de ψ(2S) para ...
Detección de patógenos antes, durante y después del proceso de cocción en alcapurrias de jueyes (Cardisoma guanhumi Latreille, 1825)
(2005)
“Alcapurrias de jueyes” are one of autochthonous Puerto Rican foods. The batter of this product is a mix of green banana (Musa paradisiaca), tannier (Xanthosoma spp.) and /or cassava (Manihot esculenta). The batter is ...
Remote sensing of suspended sediment in Mayagüez bay associated with Inland soil erosion rates
(2009)
This study combined in situ optical measurements, satellite derived reflectance and geospatial data to evaluate total suspended sediment (TSS) spatial and temporal variations in Mayagüez Bay and their relationship with ...
Effect of distributed energy storage systems in the voltage stability of an island power system
(2006)
In this work the author studies the effect of energy storage systems (ESS) used as distributed reactive compensation for voltage stability of an island power system. The dynamic voltage behavior using four load models was ...
Factores que afectan la propagación y establecimiento de Avicennia germinans L. en ambientes degradados de regiones semiáridas subtropicales
(2005)
Massive mortality in mangrove stands was reported during the 1990’s in Jobos
Bay National Estuarine Research Reserve (JOBANNER). At the present the recruitment
and growth of Avicennia germinans seedlings are negligible. ...
Fast piecewise linear predictors for lossless compression of hyperspectral imagery
(2003)
Image compression of hyperspectral is necessary because of the large storage requirements. The main objective of this research is to develop and implement fast and good predictors, for use in lossless compression of ...
