Equations for estimation of solar UV, PAR and IV in polyethylene greenhouse
(Fundacion General Univ Politecnica Madrid, 2014-01-01)
In this work are shown annual and monthly evolutions of (H) over bar (IN)(G), (H) over bar (IN)(UV), (H) over bar (IN)(PAR), (H) over bar (IN)(IV) solar radiations and (K) over bar (UV), (K) over bar (PAR) e (K) over bar ...
Low temperature performance of proton irradiated strained SOI FinFET
(Ieee, 2017-01-01)
This paper studies for the first time the low temperature characteristics of strained SOI FinFETs submitted to proton irradiation. Both types of transistors, nMOS and pMOS, were analyzed from room temperature down to 100K, ...
Cirrus clouds observation in Santa Maria, Rio Grande do Sul during the experiment Chuva - Sul.
(Chuva ProjectSão Paulo, 2013-05-08)
Cirrus clouds are an interesting point in the research of the atmosphere due their behavior and the effect on the earth radiation budget. They can affect the atmospheric radiation budget by reflecting the incoming solar ...
Weight vector estimation of circular arrays of antennas using Artificial Neural Networks
(2008-12-01)
This paper presents a model for the control of the radiation pattern of a circular array of antennas, shaping it to address the radiation beam in the direction of the user, in order to reduce the transmitted power and to ...
Annual and monthly mean global, direct and diffuse solar irradiation in Botucatu/SP/Brazil
(2011-12-01)
This paper presents a climatic and statistical analysis of global, direct horizontal and diffuse radiation from a database of solar radiation measured from 1996 to 2006 in the city of Botucatu, SP, Brazil. Variation intervals ...
Estimation of hourly, daily and monthly mean diffuse radiation based on MEO shadowring correction
(Elsevier B.V., 2014-01-01)
A statistical estimate model for the anisotropic diffuse fraction as a function of clearness index K-T is proposed to estimate hourly, daily and monthly diffuse irradiations. Global, diffuse and direct solar irradiances ...
Using solar radiation pressure to maneuver a spacecraft in the triple asteroid 2001SN263
(2016-01-01)
The number of missions which with an asteroid as a target has increased and this type of exploration will become even more frequent in the future. Space missions require high costs and methods that may reduce them should ...

(Univelt Inc, 2016-01-01)
The number of missions which with an asteroid as a target has increased and this type of exploration will become even more frequent in the future. Space missions require high costs and methods that may reduce them should ...
UV Dose Investigation for Imersed Lamp Purifier for Electronic Ballast UV Lamps design
(Ieee, 2014-01-01)
This paper presents a methodology of an electronic ballasts design for UV lamps filtering system, providing adjustable UV dose in order to ensure the inactivation of microorganisms' reproduction that are harmful to human ...
Enhanced Model for ZTC in Irradiated and Strained pFinFET
(Ieee, 2017-01-01)
This paper presents for the first time the inclusion of a p-type transistor in the CM (Camilo/Martino) ZTC (Zero Temperature Coefficient) analytical model. It was used for strained SOI pFinFETs submitted to proton radiation, ...
