NmF2 trends at low and mid latitudes for the recent solar minima and comparison with IRI-2012 model
(Elsevier, 2017-07)
The ionospheric electron density peak (NmF2) is analyzed for the recent minima of solar activity for two mid-latitude stations, Rome (41.8°N, 12.5°E, geomagnetic latitude 41.7°N, Italy) and Gibilmanna (37.9°N, 14.0°E, ...
NeQuick 2 total electron content predictions for middle latitudes of North American region during a deep solar minimum
(Elsevier, 2017-02)
The performance of NeQuick 2 model in computing the vertical total electron content (VTEC) over a wide region placed at middle latitudes of North America during the deep solar minimum that occurred in 2008 has been checked. ...
Assessment of integrated performance and roof geometry for solar energy
(OPEN HOUSE INTERNATIONAL ASSOCIATION, 2016-01-01)
The roofs of houses located at middle latitudes receive significant solar radiation useful to supply their own energy demands and to feed back into the urban electricity network. However, solar panels should be properly ...
Analysis of hourly global, direct and diffuse solar radiations attenuation as a function of optical air mass
(Elsevier B.V., 2014-01-01)
The objective of this work is to verify the attenuation caused by atmospheric constituents through the relationship between global, direct and diffuse solar radiation with respect to optical air mass. The optical air mass ...
Comparative study of the equatorial ionosphere over Jicamarca during recent two solar minima
(American Geophysical Union, 2012-01-21)
It is a critical issue that whether or not the extremely deep solar minimum of solar cycle 23/24 brought serious influences on the Earth's space environment. In this study, we collected and manually scaled the ionograms ...
Behaviour of ionospheric magnitudes of F2 region over Tucumán during a deep solar minimum and comparison with the IRI 2012 model predictions
(Elsevier, 2014-01)
In this paper we analyze the behaviour of the critical frequency of the F2 region of the ionosphere (foF2) and the height of the maximum density of free electrons in F2 region (hmF2) over Tucumán (26.9°S, 294.6°E), during ...
Desenvolvimento de um tubo solar de baixo custo para iluminação natural
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2018-11-20)
Solar tubes are equipment used to transfer natural light into environments, generating energy savings during sunny periods and favoring the health of its occupants. This equipment, that has high cost and is little diffused ...
