European multidecadal solar variability badly captured in all centennial reanalyses except CERA20C

Environmental Research Letters, 2020
Long-term historic climate datasets are valuable tools to investigate climate variability, validate climate models and contextualize anticipated climate change.

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 ...

Solar Activity and Solar Oscillations [PDF]

Symposium - International Astronomical Union, 1997
Helioseismology provides us with the tools to probe solar activity. So that we can consider how the solar oscillations are influenced by that activity, we first consider the phenomena that we associate with the active Sun. The surface of the Sun is not quiet but shows evidence of convection on a wide range of scales from a few hundred kilometres ...

Standard Solar Neutrinos [PDF]

, 1996
An improved standard solar model has been used to calculate the fluxes of standard solar neutrinos. It includes premain sequence evolution, element diffusion, partial ionization effects, and all the possible nuclear reactions between the main elements ...

A Capabilities-Led Approach to Assessing Technological Solutions for a Rural Community

Energies, 2021
To improve access to affordable, reliable and sustainable energy in rural areas of the global south, off-grid systems using renewable generation and energy storage are often proposed. However, solution design is often technology-driven, with insufficient

The Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory (SDO)

, 2011
The Atmospheric Imaging Assembly (AIA) provides multiple simultaneous high-resolution full-disk images of the corona and transition region up to 0.5 R⊙ above the solar limb with 1.5-arcsec spatial resolution and 12-second temporal resolution.

The thermal and stored heat energy driving a Stirling engine for power generation

Revue des Énergies Renouvelables, 2023
South Africa’s national power grid is currently in dire straits. The lack of a dependable power supplier and rising electricity costs force the public and businesses to look for alternatives to meet their energy needs.

Asymptotic convergence to pushed wavefronts in a monostable equation with delayed reaction

, 2014
We study the asymptotic behaviour of solutions to the delayed monostable equation $(*)$: $u_{t}(t,x) = u_{xx}(t,x) - u(t,x) + g(u(t-h,x)),$ $x \in R,\ t >0,$ with monotone reaction term $g: R_+ \to R_+$.

The radial evolution of solar wind speeds [PDF]

, 2011
The WSA-ENLIL model predicts significant evolution of the solar wind speed. Along a flux tube the solar wind speed at 1.0 AU and beyond is found to be significantly altered from the solar wind speed in the outer corona at 0.1 AU, with most of the change ...

SOLAR WATER HEATER SYSTEM CONTROLLER [PDF]

Fiabilitate şi Durabilitate, 2019
A solar water heater is a solar energy system that uses the sun to heat domestic hot water. Just like a solar electric system, it uses panels to collect solar energy.
