Comparison of methods to estimate lake-surface-water temperature using Landsat 7 ETM+ and MODIS imagery : case study of a large shallow subtropical lake in southern Brazil
(2019) [Artigo de periódico]Water temperature regulates many processes in lakes; therefore, evaluating it is essential to understand its ecological status and functioning, and to comprehend the impact of climate change. Although few studies assessed ... -
Comparison of CALMET and WRF/CALMET coupling for dispersion of NO2 and SO2 using CALPUFF modelling system
(2016) [Artigo de periódico]This study aims to compare the wind and concentration field generated by a coupling of WRF/CALMET model and CALMET/CALPUFF with no introduction of any gridded wind field. The domain was located at the city of Linhares, ... -
On the reconstruction of concentration distributions form comparison of deterministic predictions to observational data
(2016) [Artigo de periódico]The dispersion of pollutants in the atmospheric boundary layer is a stochastic process but many approaches make use of deterministic models, such as the advection-diffusion equation, that determines average values. Comparison ... -
Air quality assessment and dispersion of pollutants in the region of the Thermoelectric Plant President Médici using WRF/CALMET/CALPUFF models
(2016) [Artigo de periódico]The study and monitoring of air quality is a problematic faced especially in large population and industrial centers. Regions around coal-fired thermoelectric power plants suffer with pollution caused by combustion processes. ... -
Caracterização do processo de fratura utilizando o método dos elementos discretos e as técnicas de emissão acústica
(2015) [Artigo de periódico]A aplicação de técnicas de Emissão Acústica está revolucionando a caracterização da ruptura em sólidos quase frágeis. Neste contexto a modelagem numérica deste tipo de problema pode ser de utilidade para facilitar a ... -
Employing wind tunnel data to evaluate a turbulent spectral model
(2016) [Artigo de periódico]In this study, spectra obtained from wind tunnel data are compared with a model that describes observed atmospheric neutral spectra. The investigation points out that there is a good conformity between both spectra for the ... -
Derivation of a decorrelation timescale depending on source distance for inhomogeneous turbulence in a shear dominated planetary boundary layer
(2016) [Artigo de periódico]In the literature there exists a variety of pollution of dispersion models and in general, Lagrangian stochastic models are efficient and fundamentals tools in the investigation and study of turbulent diffusion phenomenon ... -
Considerations on the diffuse seismicity assumption and validity of the G-R law in stable continental regions (SCR)
(2015) [Artigo de periódico]It is well known that seismic activity is much higher along inter-plate boundaries, decreasing markedly in intra-plate regions. Although a few locations in so-called Stable Continental Regions (SCRs) around the globe, like ... -
On a model for pollutant dispersion in the atmosphere with partially reflective boundary conditions
(2016) [Artigo de periódico]The present work is an attempt to simulate stochastic effects in a deterministic model for pollutant dispersion in the atmospheric boundary layer by the use of a probability weighted boundary condition. More specifically, ... -
Flow in the wake of wind turbines : turbulance spectral analysis by wind tunnel test
(2016) [Artigo de periódico]The interaction between the incident wind and wind turbines in a wind farm causes mean velocity deficit and increased levels of turbulence in the wake. The turbulent flow is characterized by the superposition of wind turbine ...
