Improved RCC-Based MPPT Strategy for Enhanced Solar Energy Harvesting in Shaded Environments

IEEE Access
An improved ripple correlation control (iRCC) algorithm is proposed to enable conventional ripple correlation control (cRCC) to track maximum power under uniform and partial shading condition (PSC). The proposed iRCC has two parts; the first part detects

Impact of partial shading on the output power of PV systems under partial shading conditions

IET Power Electronics, 2014
A major challenge in the photovoltaics (PV) systems is to make it energy efficient. Partial shading reduces the energy yield of PV systems and introduces multiple peaks in the P – V characteristics.

The (2√3×3)rect. phase of alkylthiolate self-assembled monolayers on Au(111): a symmetry-constrained structural solution [PDF]

, 2009
Low-energy electron-diffraction (LEED) patterns of the Au(111)(2√3×3)rect.-butylthiolate surface phase (a structure also seen in longer alkane chain thiolate self-assembled monolayers) show missing diffracted beams characteristic of glide symmetry, but ...

A Lipschitz Optimization-Based MPPT Algorithm for Photovoltaic System Under Partial Shading Condition

IEEE Access, 2019
The power–voltage curve of a photovoltaic (PV) array shows multiple power peaks under partially shading conditions (PSCs). Hence, conventional maximum power point tracking (MPPT) algorithms can not guarantee the maximum power output of the PV ...

Begin, After, and Later: a Maximal Decidable Interval Temporal Logic

, 2010
Interval temporal logics (ITLs) are logics for reasoning about temporal statements expressed over intervals, i.e., periods of time. The most famous ITL studied so far is Halpern and Shoham's HS, which is the logic of the thirteen Allen's interval ...
