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

project demonstrates the ...Read more
Author:Eng, Jeanine; Inggs, MRDate:Dec 2016Differential interferometry techniques are well known for its ability to provide centimeter to millimeter scale deformation measurements. However, in natural and agricultural areas, the presence of vegetation and the evolution of the land ...Read more
Author:De Clercq, LE; Botha, LR; Du Plessis, A; Rohwer, EGDate:Jul 2009The purpose of this study was to develop a model of the coherent excitation of the first few vibrational modes in the electronic ground state of the molecule. The model will be used in combination with an optimization algorithm to optimize a ...Read more
Author:Lynch, RADate:Jun 2002The SIMRAC project COL816 investigated the feasibility of a small, independent device monitoring local seismicity and extracting similar activity information to what can be recorded by a temporary network of seismometers. To do this seismic ...Read more
Author:Erasmus, JDate:Oct 2015The competitiveness of manufacturing in South Africa has dramatically decreased and ways must be found to increase local production. Most products are becoming more complex, calling for more sophisticated and advanced ways to design, manufacture ...Read more
Author:Takyi, A; Densmore, M; Johnson, DDate:Sep 2016Collaborative sensing among secondary users in television white space (cognitive radio) networks can considerably increase the probability of detecting primary or secondary users. In current collaborative sensing schemes, all collaborative ...Read more
