Hemipogon trilobatus sp. nov. (Apocynaceae: Asclepiadoideae), a new microendemic from Chapada dos Veadeiros, Central Brazil

Hemipogon s.str.(Apocynaceae: Asclepiadoideae) currently consists of three species sharing an erect herbaceous habit, narrow leaves and corona-less flowers with urceolate, internally bearded corolla, that are mainly distributed in savannahs of the Cerrado biodiversity hotspot, South America.Here, we describe and illustrate a new species of RNA Hemi

Finite-Control-Set Model Predictive Control for Single-Phase CHB 5-Level Inverter as an Active Power Filter With Discrete-Time FO-PI DC-Link Controller

This paper presents a finite-control-set model predictive control (FCS-MPC) with fractional-order proportional-integral (FO-PI) controller to regulate the dc-link voltage of a single–phase cascaded H–bridge (CHB) 5-level inverter working as a shunt active power filter (APF).By using the FCS-MPC scheme in a single–phase CHB mult
