Linear models based on noisy data and the Frisch scheme
linear models factor analysis identification
2015/8/7
We address the problem of identifying linear relations among variables based on noisy measurements. This is a central question in the search for structure in large data sets. Often a key assumption is...
Application of incremental Gaussian mixture models for characterization of wind field data
Application incremental Gaussian mixture models characterization
2015/6/30
Structural responses and power output of a wind turbine are strongly affected by the wind field acting on the wind turbine. Knowledge about the wind field and its variations is essential not only for ...
Comparing the Adequacy of Some Non-Homogeneous Poisson Models to Estimate Ozone Exceedances in Mexico City
MCMC Algorithms Non-Homogeneous Poisson Models Change-Points Ozone Air Pollution Mexico City
2013/3/11
We consider some non-homogeneous Poisson models to estimate the mean number of times that a given environmental threshold of interest is surpassed by a given pollutant. Seven different rate functions ...
Sensitivity Analysis of Parameters in Water Quality Models and Water Environment Management
Water Quality Model Reclaimed Water Sensitivity Analysis Degradation Coefficient Stochastic Factors
2013/3/11
The impacts of changes of various parameters and stochastic factors on water quality models were studied. The impact of deviation of the degradation coefficient on the model results was investigated. ...
Puff Models for Simulation of Fugitive Hazardous Emissions in Atmosphere
Hazardous Emissions Advection-Diffusion Equation Analytical Solutions Air Pollution Modeling Puff Models
2013/3/12
A puff model for the dispersion of material from fugitive hazardous emissions is presented. For vertical diffusion the model is based on general techniques for solving time dependent advection-diffusi...
Prediction of the Daily Mean PM10 Concentrations Using Linear Models
PM concentrations multiple linear regression principal component regression independent component regression quantile regression partial least squares regression
2009/1/4
The performance of five linear models to predict the daily mean PM10 concentrations was compared. The linear models proposed were: i) multiple linear regression; ii) principal component regression; ii...
A Sensitivity Study of the Validation of Three Regulatory Dispersion Models
Lidar ISC AERMOD UK-ADMS plume parameters regulation air quality
2008/12/18
Lidar measurements were made of the dispersion of the plume from a coastal industrial plant over three weeks between September 1996 and May 1998. 67 experimental runs were obtained, mostly of 30 min d...
