The emergence of the COVID-19 pandemic earlier this year destabilised the operations in the education sector, particularly in institutions of higher learning. Most of these institutions are now expected to teach online, assess their students using non-venue examinations and offer remote laboratory practical and experiments. However, many of these institutions were not prepared for such…

The pressing and most urgent challenge for most of the Posts in Southern Africa is to transit from its historical reputation of being a snail-paced, inefficient, loss-making and ineffective service provider to an agile, innovative, solution-driven and highly competitive service provider that strive for excellence. In this context, adoption, and diffusion of technology and digital…

This paper proposes a photovoltaic (PV) integrated shunt active power filter (SAPF) for reactive power compensation, uneven loading and compensation of harmonic current. The control of SAPF is implemented by using adaptive based current estimation algorithm to maintain power factor near to unity and source current sinusoidal at source side. The weights are calculated online…

The filter bank multi-carrier (FBMC) technique is being considered as the major candidates for the 5G schemes. The orthogonal frequency division multiplexing (OFDM) technique is used in 4G but it has drawbacks such as higher Out-of-Band (OOB) power reduction, and higher peak to average power ratio (PAPR). OFDM uses cyclic prefix (CP) extension to overcome…

This research presents the outcomes of thin layer convective drying of ginger rhizomes with different treatments using the ARS-0680 environmental chambers for the drying process. TD 1002A – Linear Heat Conduction Experimental equipment was used in measuring the thermal conductivity of the ginger samples at varied temperature levels ranging from 10oC – 60oC and drying…

Phasor Measurement Unit (PMU) is an integral device for tracking, protection, and regulation of the power network. PMU gives synchronised calculations of actual-time data for voltage phasor, current phasor, and the frequency. Placing PMU in every node to observe the power network is not realistic from an economic standpoint and even for big data management.…

This study is based on the challenges related to the low quality of education in Indonesia. One of the reasons for these challenges is the low ability of teachers to conduct professional tasks. Future demands for teachers’ professionalization will be higher, considering the rapid development of society, science and technology, and current global competitiveness. In…

In 2020, a great change occurred around the world due to the covid-19 pandemic, daily activities were restructured and thanks to technological advance it has been an ideal means to carry out remote work. With regard to education in Peru, it was paralyzed for a long time and only obtained in later months the option…

The population living in the residential area in two villages, including Pohuwato village and Pohuwato Timur village, are mostly fishermen, who live under the poverty line, meaning that the people there have low income. The objective of the present study was to explore the living condition in terms of the physical, social, and economic aspects…
