“…In more recent times, the traditional power grid has expanded to include wind, solar and hydro energy sources without much reference to intelligent grid construction that balances integration of different energy sources to the grid [2,6,7,8]. In the past, the power grid was designed to accommodate a distribution network (Example one to multiple distributions), where national or regional electricity is feed by the central generator (power stations), and the electricity is distributed to customers by a large network cable and sub-converters/transformers [9,10,11,12,13]. The challenge of balancing power demand by the power companies and the power demand of end users is common in the historical power grid [3].…”

A smart grid is an intervention technology for the massive energy demand of the world today. It combines cyber-physical technologies, information communication technology, and electrical power networks from the generating company stations to the end-users while ensuring bidirectional communication among the actors. The smart grid is a complex growing technology that is yet to reach its maturity state. This paper seeks to examine the literature on the state of the art of smart grid technology both from the industry perspective and from academia. To this end, a literature review with a qualitative deductive approach built on the National Institute of Standards and Technology (NIST) guideline and the simplified International Telecommunication Union Telecommunication Standardization Sector (ITU-T) five-domain model were used as a guide to this research. Furthermore, the paper reviewed Smart Grid data centre topologies and identified prospects in spine-leaf architecture as a promising architecture that can be adapted in a smart grid ecosystem data centre design. The literature was searched from the databases: IEEE Xplore Digital Library, Springer Link Digital Library, and Google Scholar, IET Digital Library, Frontiers Library, ACM Digital Library repositories resulting in 151 papers after several exclusions. The work reviewed relevant literatures published from 2002 to 2021 and grouped the reviewed papers according to the key domains of the NIST/ITU-T model. Based on the evaluated literature, the need for more built-in predictive learning curves in smart grid systems and robust Smart grid architecture with enhanced data centre design for Smart grid systems is observed and recommended Keywords: Smart Grid, Smart Metre, Data Centre Computing, Distributed Energy, Protocols

“…Information and Communication Technologies (ICT) Can be defined as a different set of Technological tools and resources used to communicate, create, disseminate, store and manage information [4]. ICT has a pivotal role to play in human life ranging from cyber security to speech translations [5][6] [7]. However, its role in an educational system in which primary education is the basic can never be neglected.…”

The integration of Information and Communication Technology (ICT) in the educational systems of both public and private primary schools in Africa has become a crucial factor in enhancing teaching and learning. This paper explores the role of ICT tools in education, including computers, interactive whiteboards, learning management systems, educational apps, online collaboration tools, television, and online assessment tools. It discusses their applications and the advantages they offer, such as fostering creativity, improving academic performance, increasing motivation and responsibility, and promoting teamwork. However, it also acknowledges the challenges associated with ICT integration, including distractions, excessive usage, exposure to false information, data theft, reduced human contact, and cyberbullying. Moreover, the paper highlights key challenges in African education, such as the lack of computer literacy among instructors, low teledensity, unstable power supply, inadequate financing, and the absence of a comprehensive ICT curriculum. It concludes by emphasizing the need for a holistic approach to ICT integration, addressing infrastructure, teacher training, curriculum development, and organizational support to realize the full potential of ICT in education especially at the Primary school level.

<span lang="EN-US">Pathloss is a key element that causes signal deterioration in the channel as the signal power reduces inversely with propagation distance, this deterioration experienced by the channel is majorly as a result of reflection, absorption, and scattering of the signal. This study however takes into consideration the radio path loss for precise base station (BS), frequency, and power adjustment prediction evaluated over a frequency of 2.3 GHz. With a distance range between 0.1 and 1.5 km for collection of data on the measured received signal strength (MRSS), five empirical models and a modified model were used to validate the measured data to determine their suitability for pathloss prediction at Federal University of Technology, Owerri (FUTO), Imo state, Nigeria. The results shows that the root mean square error (RMSE) for the Okumura-Hata, COST 231-Hata, Ericsson model, Lee, Stanford University Interim (SUI), ECC-33, and modified models are 14.33, 9.73, 25.79, 48.4, 33.76, and 8.31 dB respectively. Additionally, the Ericsson model provided 0.498 dB, the COST 231-Hata recorded 0.733 dB, and the modified model provided 0.453 dB for mean absolute percentage error (MAPE). Therefore, the improved model produces the best results, consequently, be deployed to approximately predict path loss for mobile radio coverage in Owerri, Nigeria.</span>
