Assessing the performance of physical transposition models in photovoltaic power forecasting: A comprehensive micro and macro accuracy analysis

Energy Conversion and Management: X
Accurate power prediction is crucial for the design, simulation, and performance assessment of Photovoltaic (PV) systems. Achieving this accuracy relies significantly on the precise plane-of-array (POA) irradiance data, which is seldom directly measured.

Solar Energy Potential on Surfaces with Various Inclination Modes in Saudi Arabia: Performance of an Isotropic and an Anisotropic Model

Applied Sciences, 2022
The present work investigated the performance of an isotropic (Liu–Jordan, L–J) and an anisotropic (Hay) model in assessing the solar energy potential of Saudi Arabia. Three types of solar collectors were considered: with southward fixed-tilt (mode (i)),

Transposition in plants: a molecular model [PDF]

The EMBO Journal, 1985
A molecular model for transposition of plant transposable elements is described. This process may occur via excision and re-integration of the element. Excision generates DNA sequence diversity which suggests the participation of DNA repair enzymes in the healing of the donor molecule.
