Quality Analysis of Photovoltaic System Using Descriptive Statistics of Power Performance Index

open access: yesIEEE Access, 2023
The performance evaluation (PE) of the Photovoltaic(PV) system is an index representing the efficiency and reliability of the system. Most PE indicators evaluate the ratio of theoretically calculated power generation to actually measured power generation.

Hopf-cyclic homology and cohomology with coefficients [PDF]

open access: yes, 2003
Following the idea of an invariant differential complex, we construct general-type cyclic modules that provide the common denominator of known cyclic theories. The cyclicity of these modules is governed by Hopf-algebraic structures.
