Proposed algorithm MPPT for Photovoltaic system

International Journal of Energetica, 2018
A proposed algorithm MPPT (Maximum Power Point Tracking) is proposed in this paper. When the insolation change rapidly, the P&O (Perturb and Observe) algorithm is used to adjust the operating point of the PV (Photovoltaic) array close to the MPP (Maximum Power Point) for fast tracking; also, the INC (Incremental Conductance) algorithm and the fuzzy

Efficacy of Biologics for Surgical Treatment of Periodontal Suprabony Defects: A Systematic Review and Meta‐Analysis of Controlled Clinical Trials

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim Limited bone support in suprabony defects hinders predictable regeneration, but adjunctive biologics can improve results. This systematic review and meta‐analysis aimed to evaluate the clinical efficacy of adjunctive biologics combined with open flap debridement (OFD) compared with OFD alone when treating suprabony defects.

Patient‐reported outcome measures and health economics in regenerative periodontal therapy: A systematic review and meta‐analysis

Periodontology 2000, EarlyView.
Abstract Understanding patient responses to periodontal regeneration is crucial. This systematic review and meta‐analysis addressed two key questions: (a) the impact of periodontal regeneration on patient‐reported outcome measures (PROMs) for intrabony and furcation involvement and (b) the cost‐effectiveness of periodontal regeneration for treating ...

Long‐term clinical outcomes of periodontal regeneration of intrabony defects: A systematic review and meta‐analysis

Periodontology 2000, EarlyView.
Abstract This systematic review and meta‐analysis aimed to evaluate the long‐term clinical outcomes of regenerative procedures compared with access flap surgery for the treatment of intrabony defects, with a minimum follow‐up period of 5 years. A systematic review protocol following PRISMA guidelines was conducted.

Towards Contactless Daylight Photoluminescence of PV Strings During Operation by Electrical Modulation

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 2, Page 200-216, February 2026.
dPL usually requires two states (ON/OFF) to distinguish light from the panels from ambient light. dPLS(N): an electronic device forces a sub‐string of S‐N panels (a string of S panels) to work at two different points on the I‐V curve. In this example (S = 20), dPL20(6) shows a perfect square modulation of the current intensity throughout the ...
