Agu John paul is currently a master’s student in the Faculty of Engineering, Department of Mechanical Engineering, University of Nigeria Nsukka. His research work is focused on the Experimental Investigation of the Effects of Biomass Ash Content of Aluminum Matrix Composite On the Thermal Loading of Orthogonal Cutting Tools
In this research work, an experimental investigation will be carried out to determine the effect of varying factors such as the percentage content of biomass ash, spindle speed, depth of cut and feed on the thermal loading of orthogonal cutting tools during machining as a function of the machinability.
This experimental study when completed is expected to furnish engineers and machinists with relevant information on the thermal effects of machining aluminum-biomass ash composites of different volumes and also give information on the optimal combination of machining parameters; feed, spindle speed, and depth of cut for machining aluminum-biomass ash matrix composites.
Maxwell Ballot is currently a master of Engineering Student, Micro Electronic Engineering, University of Pretoria, South Africa.
His research is focused on a Gallium Nitride low-noise amplifier with oscillation based built-in self-testing. It explores the viability of using oscillation-based built-in self-testing to increase the reliability of wideband GaN low noise amplifiers for electronic warfare applications. Presently, there is a very limited amount of Built-in self-testing methods for wideband systems. Current built-in self-testing methods, for low noise amplifiers, focus on relatively narrow band applications.
However, adding a reliable dedicated test source is not optimal, as it is subjected to the same harsh environment as the device-under-test, therefore oscillation-based built-in self-testing could address the need for a reliable wideband test method. This will be initially applied to a wideband GaN low-noise amplifier but could be expanded on to become a generalized wideband test method. When this research is completed, the system is expected to address the reliability problems of wideband EW LNAs and should also focus on producing a system that monitors LNA health consistently. Therefore, the OBIST system’s efficacy in monitoring degradation should be determined. It is also important that the test system maintains accuracy during operation and is also relatively immune to process variation.
The research result is also expected to produce better receivers and an OBIST method that could be applied to wideband amplifiers in general. This could provide testing methods for systems in space where accessibility is a constraint.
Adefunrin Sunday Sefunmi, Master of Science Student, Faculty of Social Science, Department of Geography Obafemi Awolowo University, Ileife, Nigeria, is currently conducting research on the assessment of the Spatio-temporal effect of climate dynamics on biodiversity extinction of Okitipupa forest reserve in Ondo state.
The research methodology will involve physical observation and a pilot survey to determine the effect of climate dynamics and the present nature of the biodiversity component of the forest.
The Global Positioning System will be used to take the coordinates and calculate the area of the forest reserve. High-resolution satellite images of Okitipupa area downloaded from Google earth in the interval of 10 years spanning 1998, 2008 and 2018 will be acquired and preprocessed using ARCGIS version 10.3 software. Classification (supervised and unsupervised) will be conducted on the images to determine the changes in terms of trend and pattern that has occurred in the study area over the spread of 30 years. Spatial data analysis techniques such as krigging, neighborhood function, trend surface analysis, intersection analysis, and autocorrelation will be adopted to compare the changes that have occurred over time.
From the expected results, necessary inferences will be drawn objectively and recommendations will be made to all concerned agencies, authorities, government, corporate Organizations and potential users of the forest resource, on the condition of the bio-diversities in the forest. Strong emphasis will be made on the need to adopt tolerance, avoidance and adaptation approaches in order to ensure the sustainability of the forest ecosystem.
Hendrik Petrus Ne, a master of Engineering Student, Micro Electronic Engineering, University of Pretoria, South Africa, is conducting a research on the Implementation and design of an oscillation based testing (OBT) architecture as a calibration strategy in radiometers, more speciﬁcally in mm-wave water vapour radiometers.
By using an automated calibration technique, through his research output, one can do calibrations of radiometers more frequently, achieve better accuracy and be able to effectively calibrate arrays of radiometers used in radio astronomy.
The research work is hoped to be very useful in SKA as a radio astronomy project utilizing large arrays of antennas and radiometers. Through this research, effective and accurate calibration of the front end electronics in a timely manner which is extremely important is hoped to be achieved. The project will also attempt to use a testing strategy as a calibration technique for automated calibration.
Alemu Habtamu Marew: PhD. Student, Space Physics, Washera Geospace, and Radar Science Laboratory, Bahir Dar University, Bahir Dar, Ethiopia.
The focus of the research is to study and model ionospheric vertical drift velocity using the equatorial electric ﬁeld and equatorial electro-jet observations of Swarm-constellation satellites (obvious missions of European space agency (ESA)).
The Swarm constellation data product of equatorial electric ﬁeld and equatorial electro-jet is recently available for researchers. Using these opportunities we will develop a data-driven vertical drift velocity model and compare with the results we already obtained in earlier work (Marew et al, 2019) and to other recently developed models (e.g., Dubazane and Habarulema (2018), Habarulema et al. (2018), etc.) as well. Large data set will be introduced to study the seasonal and annual variations of equatorial electric ﬁeld, equatorial electro-jet and ﬁnally the vertical ion drift.

ABBEY, Godson Fortune – Masters Student, Astronomy and Astrophysics department, University of Nigeria Nsukka.
Abbey Godson Fortune is conducting research in Exatra-Galactic Radio astronomy, focusing on the Unification of low luminosity radio sources. The project hopes to investigate approximately 100 different low luminosity Radio sources including Blazers and other Active Galactic Nuclei (AGN). His research work hopes to characterize these radio sources based on their luminosity and also find some common property amongst them. The result will help scientists in the understanding of AGN. Though the knowledge may seem advance currently, however, this is an area of astrophysics, which will open new Windows to how Galaxies are formed and also enhance our knowledge of the Milky Way Galaxy. The social and economic importance of this work is that our results can be used by the institutions to further understand how galaxies form, This may eventually lead to building Radio Observatories which will save the government huge cost of sending students abroad to do astronomy related observations.
Obi Odinaka Patrick-Doctorate student, Department of Physics and Astronomy, University of Nigeria Nsukka.
Obi Odinaka Patrick is conducting his doctorate research in atmospheric physics in the department of Physics and Astronomy, University of Nigeria Nsukka. His research was inspired by the search for the true mechanism between the moving earth system and space events accruing from solar variability. It is intended to contribute to the existing body of knowledge in related areas most especially the climate factor that threatens man and its environment in different parts of the world.
The aim of the research is to study the relationship between ‘solar output and its terrestrial effects’ and the atmospheric dynamics. Solar data, geomagnetic data and Ozone data are primary data to be used for the study, but not limited to them, as other atmospheric data can incorporated for the research. The results from the data analysis will be able to show the relationship between the heliospheric space event and our terrestrial space changes, such as ozone redistribution/variation and climate change.
Ojo Taiwo Theophilus: Doctorate student, Atmospheric Science, Department of Physics and Electronics, Rhodes University South Africa
Ojo Taiwo Theophilus is a doctorate student of Atmospheric Science studying in Department of Physics and Electronics, Faculty of Sciences, Rhodes University. Currently, he is conducting his research work in South Africa National Space Agency (SANSA). His research work is focused on neutral winds and tides over mid-latitudes using ionosonde, satellite, and Fabry-Perot interferometer (FPI) measurements. He is very passionate towards the research and intends to derive neutral winds using the South African ionosonde network. His research work will extract, verify and analyze tidal variation of the winds and determine their effects on the Ionosphere with the recently installed FPI in Sutherland as well as satellite measurements.
Although neutral winds and their tidal components have been studied for over several decades, this will be the first of such study conducted over the African region, furthermore, the newly installed FPI would be used to derive neutral winds over this African region for the first time. This research will in no doubt contribute immensely to the understanding and study of the behavior of thermosphere-ionosphere dynamics, as well as its effects on radio waves communication, navigation and aviation.
IDOWU Temitope Ezekiel – Doctorate student, Environmental Science, Jomo Kenyatta University of Agriculture and Technology, Kenya.
This doctorate research work is focused on investigating the potentials of seawater intrusion in the coastal aquifers of kenya using a numerical model-based approach
The main objectives of the research are;
- to assess and compare the impacts of sea level rise and groundwater abstraction rates on seawater intrusion in the coastal aquifers of two study areas- Mombasa and Malindi.
- create a numerical model for predicting the impacts of sea-level rise and population induced groundwater abstraction and predicting possible scenarios
- develop a new simulation-optimization methodology for managing possible impacts of sea-level rise and groundwater abstraction in the two study areas.
The study is significant in that the outputs of the models and the new management methodology to be created will be extremely valuable for water resources and pollution management of the coastal region. Also, its objectives fit into the larger UN agenda of “ensuring the availability and sustainable management of water (Goal 6); making cities and human settlements more sustainable (Goal 11); and combating climate change and its impacts (Goal 13)” through providing empirical data that will guide decision making at the local as well as the national level. More importantly, the research will open further doors for advances in coastal water resources management in the region and other parts of sub-Saharan Africa.
