Tailoring Model‐Based Systems Engineering for Sub‐100 g PlanarSats: A Power‐First View Stack

Systems Engineering, EarlyView.
ABSTRACT This paper addresses how to apply model‐based systems engineering (MBSE) to ultrasmall planar satellites under severe power and resource constraints. PlanarSats are sub‐100‐gram spacecraft built as single printed‐circuit boards where the same surface must host both electronics and solar cells, so power generation, geometry, and component ...

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

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 ...
