Investigation of the effects of cloud attenuation on satellite communication systems [PDF]
, 2012 The aim of this project is to investigate the attenuation due to clouds at 20- 50GHz; to develop an accurate long-term prediction model of cloud attenuation applicable to slant-path links and evaluate the impact of cloud attenuation dynamics on the ...

Time-lapse seismic attenuation as a tool for monitoring hydrocarbons and CO2 in geological materials [PDF]
, 2011 Both laboratory experiments and theoretical models have shown seismic attenuation to be sensitive to various petrophysical properties of rock and pore fluids, making attenuation a potentially useful time-lapse attribute to measure and interpret through ...

Teleseismic P-Wave Attenuation Beneath the Arabian Plate
Geosciences, 2023 In order to prove that the Arabian Plate is a tectonically active region even in its shield areas, we obtained the attenuation structure tp* of the upper mantle beneath the Arabian Plate by applying the spectral inversion method to the newly established ...

LA LÍTOTE EN SIN RUIDO DE JOSÉ CORREDOR-MATHEOS
Perífrasis. Revista de Literatura, Teoría y Crítica, 2020 Este artículo analiza el poemario del manchego José Corredor-Matheos, Sin ruido (2013), desde la óptica de la lítote como figura de atenuación y, con mayor alcance, como mecanismo que subsume ciertos rasgos transversales característicos de la poética de ...

Validation of OSEM algorithm for attenuation correction in cardiac SPECT studies [PDF]
, 2005 Photon attenuation is believed to be one of the major causes of artefacts in cardiac SPECT studies and therefore should be corrected to improve the specificity of cardiac SPECT imaging for the detection of coronary artery disease.

Approximation through suffixation: -ḍḍu/-a in Sicilian
Zeitschrift für Wortbildung, 2023 This article investigates the use of the Sicilian suffix -ḍḍu/-a for the expression of approximation. On the basis of a survey of a corpus of ethnotexts and the outputs of a translation questionnaire, we propose that approximation is a core value in the ...
