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 ...
Sieve bootstrap en series de tiempo de nubosidad en el caribe
(2006)
The Sieve Bootstrap is a resampling method, designed to deal with autocorrelated data, specifically a sequence of information taken at equal time intervals. Formally, the Sieve Bootstrap approximates a linear process by a ...
Estimation of relative humidity in Mesoamerica and Caribbean region using satellite data
(2017)
This work addresses the estimation of the relative humidity (RH), which is related to the way the body reacts under extreme hot events, and in consequence has influence in human health. RH is commonly obtained from ground ...
Detection of climate changes over the global and Caribbean basin
(2007)
The statistical test developed in this research was able to find punctual changes at any time series. In this way the studied variables including sunspot, global carbon dioxide, air surface temperature, cloud cover and sea ...
Statistical techniques for testing batch to batch variability and accelerated testing
(2011)
The purpose of stability studies is to determine the shelf life of drug products. The
period between the date of manufacture and expiration date of a given product is known as
the shelf life, and consequently the shelf ...
Modelo con retraso y correlación cruzada para predecir intensidad de la lluvia a corto plazo
(2012-08)
El uso de los sistemas de cómputo, permitido el mejor acondicionamiento de las predicciones que se realizan de los fenómenos atmosféricos. Sin embargo, aún este tipo de predicciones es un reto que se les presenta a la ...
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 ...
Diseño de un algoritmo de secuenciación aplicado a la manufactura de implantes para las arterias coronarias
(2009)
This study presents first a method to assign a number of lots to a given set of manufacturing modules to maximize productivity, taking into account the constraints of production capacity, demand, and designing an appropriate ...
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 ...
Redes neuronales artificiales y funciones de transferencia aplicados a la estimación de humedad de suelo y temperatura del aire
(2007)
Statistical, mathematical and artificial neural networks techniques were used to estimate the
behavior of the following variables: the air temperature (AT) and the soil moisture (SM).
The AT plays an important role in ...
