Transparency of cosmic radio waves caused by seismic and volcano activities
(Scientific Research Publishing Inc, 2014)
Evaluation of uncertainty in gravity wave potential energy calculations through GPS radio occultation measurements
(Elsevier Sci Ltd, 2013-05)
The application of the Global Positioning System (GPS) radio occultation (RO) method to the atmosphere enables the determination of height profiles of temperature, among other variables. From these measurements, gravity ...
Estimated errors in a global gravity wave climatology from GPS radio occultation temperature profiles
(Elsevier, 2010-07)
In a previous paper by Schmidt et al. (2008), from CHAllenging Minisatellite Payload (CHAMP) Global Positioning System (GPS) radio occultation data, a comparison was made between a Gaussian filter applied to the "complete" ...
Radio and optical techniques for locating equatorial plasma irregularities
(University of Illinois, 2009)
Irregularities in the plasma density, especially dynamic, turbulent irregularities, may have profound effects on radio waves passing through the ionosphere. A class of these equatorial F-region irregularities is the subject ...
Estudo de modelos de radiopropagação para a recepção de TV utilizando antena de transmissão na polarização horizontal e elíptica
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2018-10-04)
Due to the need for more and more elaborate and precise television projects, this work consists of a study on the application of propagation models for broadcasting projects based on the data obtained from the field tests ...
Radio-frequency spectroscopy of (6)Li p-wave molecules: Towards photoemission spectroscopy of a p-wave superfluid
(AMER PHYSICAL SOC, 2010)
We study rf spectroscopy of a lithium gas with the goal to explore the possibilities for photoemission spectroscopy of a strongly interacting p-wave Fermi gas. Radio-frequency spectra of quasibound p-wave molecules and of ...
Prospects for radio observations of Particle-Accelerating Colliding-Wind Binaries with the Giant Metrewave Radio Telescope
(Societè Royale de Sciences de Liege, 2020)
Synchrotron radiation identified in the radio domain for several tens of binary systems made of massive stars provides compelling evidence that a particle acceleration process is at work in these objects, hence their ...
An improvement of the sensitivity of GPS radio occultation data to detect gravity waves through observational and modeling factors
(Elsevier, 2015-10)
There is a mid-latitude region to the East of the Andes Range in the Southern Hemisphere that exhibits ideal conditions for the generation of gravity waves (GW) by topography mainly during winter. The configuration favors ...
On the determination of gravity wave momentum flux from GPS radio occultation data
(European Geosciences Union, 2013-11)
Global Positioning System (GPS) radio occultation (RO) is a well-established technique for obtaining global gravity wave (GW) information. RO uses GPS signals received by low Earth-orbiting satellites for atmospheric limb ...
