Author:Govender, Avashna; King, SDate:Nov 2023Cognitive load of text-to-speech (TTS) synthesis systems measured in the past consistently showed that processing synthetic speech is more difficult to process than human speech in the presence of noise. However, the systems previously evaluated ...Read more
Author:Ogbodo, EU; Dorrell, D; Abu-Mahfouz, Adnan MIDate:Sep 2017The cognitive radio-based sensor network (CRSN) is envisioned as a strong driver in the development of modern power system smart grids (SGs). This can address the spectrum limitation in the sensor nodes due to interference cause by other ...Read more
Author:Onumanyi, Adeiza J; Abu-Mahfouz, Adnan MI; Hancke, GPDate:Nov 2019Some recent survey statistics suggest that low power wide area networks (LPWANs) are fast becoming the most prevalent communication platform used in many applications of the Internet of things (IoT). However, because most LPWANs are generally ...Read morecb
