Abstract: This paper introduces a novel single-loop control scheme for voltage regulation in islanded inverters, using a proportional-integral-lead (PI-Lead) controller designed within the synchronous ...

Discover a fast and powerful calculus-based method for finding square roots with impressive accuracy. This explanation shows how derivatives and iterative approximation can be used to quickly zero in ...

Plant material was collected from the native habitats of each taxon, and voucher specimens were deposited in the Sangji University Herbarium (SJUH) (Supplementary Figure S1, Supplementary Table S1).

Background: This systematic review and meta-analysis aimed to quantify the association between environmental and occupational lead exposure and the risk of various hypertension subtypes. We further ...

Hunters are being urged to stop using lead bullets because bald eagles and other wildlife that consume carcasses left behind are often sickened by lead poisoning. Late fall and early winter is deer ...

Abstract: The article considers the possibility of introducing modern regulation methods into the control system of NK-12ST gas turbine engine. It is proposed to use a combination of PI control and ...
