Orbital dynamics of "smart dust" devices with solar radiation pressure and drag [PDF]

open access: yes, 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 ...

Computation of irradiance in a solar still by using a refined algorithm [PDF]

open access: yes, 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 ...

Visibility and potential of solar energy on horizontal surface at Kuwait Area [PDF]

open access: yes, 2011
In this paper, an overview of the production and consumption of Kuwait electrical energy, installed capacity and peak loads are presented. The results show that Kuwait has a serious situation because of the electrical energy lacking and load peaking ...

Orbital dynamics of earth-orbiting 'smart dust' spacecraft under the effects of solar radiation pressure and aerodynamic drag [PDF]

open access: yes, 2010
This paper investigates how the perturbations due to asymmetric solar radiation pressure, in presence of Earth's shadow, and atmospheric drag can be balanced to obtain long-lived Earth centered orbits for swarms of SpaceChips, without the use of active ...

PV system sizing using observed time series of solar radiation [PDF]

open access: yes, 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

Performance Evaluation of Artificial Neural Networks in Estimating Global Solar Radiation, Case Study: New Borg El-arab City, Egypt

open access: yesEnvironmental Science and Sustainable Development, 2017
The most sustainable source of energy with unlimited reserves is the solar energy, which is the main source of all types of energy on earth. Accurate knowledge of solar radiation is considered to be the first step in solar energy availability assessment.
