Predição de cobertura radioelétrica em terrenos irregulares iluminados por fonte de onda esférica: uma abordagem via equações integrais e CBFM
(Universidade Federal de Minas GeraisUFMG, 2011-10-03)
This work deals with the forward and backward propagation prediction of electromagnetic fields over irregular terrains in the VHF-UHF bands (30 MHz to 3 GHz) that is necessary in wireless planning. The terrain is modeled ...
Groundwater favorability map using GIS multicriteria data analysis on crystalline terrain, Sao Paulo State, Brazil
(ELSEVIER SCIENCE BV, 2008)
This paper presents the groundwater favorability mapping on a fractured terrain in the eastern portion of Sao Paulo State, Brazil. Remote sensing, airborne geophysical data, photogeologic interpretation, geologic and ...
Multiscale Analysis of Topographic Surface Roughness in the Midland Valley, Scotland
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
Surface roughness is an important geomorphological variable which has been used in the Earth and planetary sciences to infer material properties, current/past processes, and the time elapsed since formation. No single ...
Predição de cobertura radioelétrica em terrenos irregulares usando método de funções de base características
(Universidade Federal de Minas GeraisUFMG, 2011-11-16)
This work deals with the propagation of electromagnetic waves in the VHF (Very High Frequencies) and UHF (Ultra High Frequencies) bands over irregular terrain. This study is concerned in development an computationally ...
TOPOGRAPHIC REGISTERS OF PALEO-VALLEYS ON THE SOUTHEASTERN BRAZILIAN CONTINENTAL SHELF
(INST OCEANOGRAFICO, UNIV SAO PAULO, 2009)
The evolution of paleo-incised-valleys in the Sao Paulo State region of the southeastern Brazilian continental shelf is presented in this study in relation to the post Last Glacial Maximum (LGM) sea-level rises based on ...
Perception of wheeled mobile robots in agriculture: phenotyping and mobility assessment
(2019)
Agricultural production must double by 2050 in order to meet the expected food demand due to population growth. Within the technologies employed and developed to achieve this goal, research on development of intelligent ...
Testing stabilization of high-plasticity clays used in sloping terrain by adding sodium silicate
(Journal of Physics: Conference SeriesReino Unido, 2020-08-05)
High-plasticity clays can be stabilized by the addition of a small percentage of sodium silicate. Sixteen mixtures of 4000 g with different concentrations of sodium silicate at difference percentage were designed, to which ...
