Heliotropic dust rings for Earth climate engineering [PDF]
, 2013 This paper examines the concept of a Sun-pointing elliptical Earth ring comprised of dust grains to offset global warming. A new family of non-Keplerian periodic orbits, under the effects of solar radiation pressure and the Earth's J(2) oblateness ...

Orbital dynamics of "smart dust" devices with solar radiation pressure and drag [PDF]
, 2011 This paper investigates how perturbations due to asymmetric solar radiation pressure, in the presence of Earth shadow, and atmospheric drag can be balanced to obtain long-lived Earth centred orbits for swarms of micro-scale 'smart dust' devices, without ...

PV system sizing using observed time series of solar radiation [PDF]
, 2006 Sizing represents an important part of photovoltaic system design. This paper describes a sizing procedure based on the observed time series of solar radiation. Using a simple geometrical construction, the sizing curve is determined as a superposition of

Computation of irradiance in a solar still by using a refined algorithm [PDF]
, 2013 A refined solar algorithm from the ESP-r system has been used to calculate the distribution of solar irradiation inside a basin-type solar still. In the approach, surface finish, view factors and multiple reflections are taken into consideration in the ...
