Driving training‐based optimization (DTBO) for global maximum power point tracking for a photovoltaic system under partial shading condition

IET Renewable Power Generation, 2023
The presence of bypass diodes in photovoltaic (PV) arrays can mitigate the negative effects of partial shading conditions (PSCs), which can cause multiple peak characteristics at the output.

Sand cat swarm optimization based maximum power point tracking technique for photovoltaic system under partial shading conditions

International Journal of Electrical Power & Energy Systems
Maximum power point tracking (MPPT) plays a crucial role in photovoltaic systems (PVS). In partial shading conditions (PSCs), the P-V characteristic curves of PVS exhibit multiple peaks. Traditional MPPT algorithms, like perturbation and observation (P&O)

Transcriptional profiling directs the classification of acute leukemias of ambiguous lineage into AML, B-ALL, or T-ALL. [PDF]

Hemasphere
Abstract Acute leukemia of ambiguous lineage (ALAL) is a rare, poor‐prognosis acute leukemia subtype that cannot be assigned to a single hematopoietic lineage. Although ALAL patients are typically treated with acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL) regimens, optimal treatment choice is hindered by their lineage ambiguity ...

Maximum power point tracking in partially shaded photovoltaic systems using grasshopper optimization algorithm

IET Renewable Power Generation, 2023
The P–V curve of photovoltaic (PV) arrays has several peaks under partial shading conditions (PSCs). Therefore, to extract maximum power, it is necessary to detect its global maximum power point (GMPP). The conventional maximum power point tracking (MPPT)
