Differential evolution-based pulse-width modulation technique for multiphase MC
(
Institution of Engineering and Technology
, 2019 , Article)
This paper addresses multiphase matrix converter (MPMCs) modulated with Venturini's classical scalar approach. The solution to obtain time-varying modulation functions was limited to 3 × 3 configuration, which was later ...
Eggshell membrane as a novel bio sorbent for remediation of boron from desalinated water
(
Academic Press
, 2018 , Article)
This study investigated the use of eggshell membrane (ESM) as a bio-sorbent and the effect of temperature, pH, and initial concentration on its efficiency. Furthermore, by altering the chemical composition, modified eggshell ...
Analysis of spatial data with a nested correlation structure
(
Blackwell Publishing Ltd
, 2018 , Article)
Spatial statistical analyses are often used to study the link between environmental factors and the incidence of diseases. In modelling spatial data, the existence of spatial correlation between observations must be ...
The Ramsey number for two graphs of order 5
(
Taylor and Francis Ltd.
, 2018 , Article)
For two graphs F1 and F2, the Ramsey number R(F1, F2) is the smallest positive integer r such that for every graph G on r vertices, G contains F1 as a subgraph or the complement of G contains F2 as a subgraph. We present ...
Epigenetic mechanisms, trauma, and psychopathology: Targeting chromatin remodeling complexes
(
