The filtered-orthogonal frequency division multiplexing (F-OFDM) scheme has gained attention as a promising solution in the field of visible light communication (VLC) systems. One crucial aspect in VLC is the conversion of the complex F-OFDM signal into a real signal that corresponds with direct detection and intensity modulation. Traditionally, achieving a real F-OFDM signal has involved imposing Hermitian symmetry (HS) on the samples of the Inverse Fast Fourier transform (IFFT), which require...

This study aimed to explore the perspectives of EFL instructors working in a variety of universities in the UAE on the effectiveness of AI applications in the EFL classroom. EFL teachers need to use AI applications in ways that are aligned with instructional goals and support student learning. A quantitative approach was used, and data was gathered from a survey of 46 EFL instructors. The results showed that the instructors strongly relied on AI applications to facilitate tasks, offer datadrive...
Ownership structures and corporate governance: A systematic analysis

Feb 20, 2024
This study aimed to analyze the ownership structures and corporate governance. Good corporate governance helps companies become more efficient, improve access to finance, reduce risk, and avoid substandard governance (Kontogeorga et al., 2022; Mustafa & Morina, 2022; Prasad et al., 2022; Lapina et al., 2016; Raja & Kostyuk, 2015). The study has followed a qualitative research paradigm and systematic review protocol, specifically the PRISMA technique, and included 65 papers published in journals...
