Comparative Evaluation of SVPWM Duty-Cycle Calculation Methods for Two-Level and Quasi-Two-Level Flying-Capacitor Inverters

Abstract This paper presents a controlled and reproducible comparison between two duty-cycle computation routes for space vector pulse width modulation (SVPWM) applied to three-phase two-level inverters: the classical trigonometric formulation and the algebraic g , h approach. Bo...

Strategic Lignin Fractionation: Sustainable Encapsulation and Controlled Release of Pelargonic Acid

Abstract Interest in bio-based herbicides, such as pelargonic acid (PA), a naturally occurring fatty acid with rapid post-emergent herbicidal activity, has increased in response to the growing demand for sustainable and effective weed-control strategies. However, its practical ap...

Integrating the Classical and Molecular Approaches Toward Passion Fruit Resistance Against CABMV

Abstract Passion fruit, a tropical species cultivated across various nations, faces challenges in expanding its cultivation areas due to several constraints, including total crop losses, caused by the fruit woodiness virus. In Brazil, this condition is attributed to the cowpea ap...

An asymptotic model for drug dissolution in a standardized flow-through apparatus

Abstract Asymptotic methods are employed to analyse, interpret and improve on an often-used model for the dissolution of drug particles in a standardized flow-through dissolution cell, United States Pharmacopeia Apparatus 4 (USP4). The model is based on a simplified description f...

Blending PCI Coal and Biochar as Sustainable Alternative for Blast Furnace Fuels

The aim of this study was to investigate the feasibility of using biochar or its blends with pulverized coal injection (PCI) coal as a potential blast furnace (BF) fuel. A comparison was conducted between the properties of biochar obtained from the pyrolysis of coconut shell and...
