    (2020-09-25) Ahinon, Justin, Sègbédji; Arafat, Hisham; Ahmad, Umar; Achampong, Joyce; Aldirdiri, Osman; Ayodele, Obasegun, Tekena; Bezuidenhout, Louise; Okelo, Luke; Cary, Michael; Fath, Nada; Ksibi, Nabil, Aziz; Zimmer, Niklas, Carl; Nasr, Fayza; Nguemeni, Carine; Maina, Mahmoud, Bukar; Mensah, Priscilla; Obanda, Johanssen; Owango, Joy; Ogunlaja, Ahmed; Simpson, Gregory; Havemann, Johanna
    AfricArXiv is a community-led digital archive for African research working towards building an Africa-owned open scholarly repository; a knowledge commons of African scholarly works. We are partnering with established scholarly repository services to provide a platform for African scientists of any discipline to present their research findings and connect with other researchers – on the African continent and globally. It is our aim to promote discoverability of African research output according to sfDORA : https://sfdora.org/read/ FAIR principles: https://www.go-fair.org/fair-principles/ Helsinki Initiative on Multilingualism: https://www.helsinki-initiative.org/en To contextualize the above to the African scholarly community we have postulated 10 African Principles for Open Access in Scholarly Communication: https://info.africarxiv.org/african-oa-principles/

    Development of a Competitive and Collaborative Platform for Block Diagram and Resistive Circuit Reduction in a Basic Electrical Engineering Course
    (2018-09-10) Ayodele, Obasegun, Tekena
    Competition and collaboration are two universal ingredients in all human cultures. Competition has been observed over time as a phenomenon that has helped people achieve the very best of their potentials in their various fields. Competition has also helped individuals achieve feats they would not have ordinarily achieved as they are pushed beyond their limits. The same can also be said of cooperation and collaboration, which can be used to achieve specific goals or objectives. Hence, both competition and collaboration can be vital in creating a healthy learning process among students. This paper discusses a competitive and collaborative platform on the learning process for two selected online courses in Electrical Engineering. Using a platform developed in LabVIEW programming language, a community of students were encouraged to compete online as they try to reduce block diagrams of subsystems in Control Engineering as well as reduce given Series-Parallel Resistor Circuits in the shortest time and amount of steps possible. At the end of each trial, students can view the finish time of other students and can share, online, their individual solutions with the community as well as discuss ideas such as reduction techniques they find most expedient via a public online notepad. This creates a means of learning from the community. The platform helps to passively induce a competitive and collaborative perspective in the learning pathway of students, thereby improving the interest and experience of students in the selected subject areas. The platform uses an online server to maintain communications from all the students in their various locations. Students can view the timed performance of their counterparts on a leadership board thereby engendering induced competition in the learning community. The instructor or administrator can also monitor activities in the community from a server portal.

    Development of a Module to Teach Basic Concepts of Interfacing and Connectivity in Internet of Things
    (2018-09-10) Ayodele, Obasegun, Tekena
    This paper presents a basic laboratory training module aimed at helping undergraduate students understand the interfacing and connectivity issues involved in the Internet of things (IoT). The training module uses a sequential teaching approach to draft quasi-experiments for teaching basic IoT concepts. Interfacing includes identification, embedded sensing and embedded actuating while connectivity includes wireless connectivity and web/ mobile services. An IoT function (control and/or measurement) is first selected by users based on the physical variable of interest and the action to be carried out. The user will also select a connectivity option based on network types and transmission technologies available for communication between a sensor and/or an actuator and a gateway. The available connectivity options in this work are Bluetooth and RF. An interface is then setup based on the choices made using Arduino Pro Mini as microcontroller. Arduino Yun and a smartphone are the available gateway options depending on the connectivity option of the interface. When Bluetooth is the connectivity type on the interface, the smartphone is used as gateway while Arduino Yun serves as the gateway when RF is the connectivity option on the interface. The training module is accompanied with an instruction manual which contains instructions on the set ups and short notes on signals and systems, Analog to Digital Converters (ADC), Digital to Analog Converters (DAC), Wireless Sensor Networks (WSN), etc. The training module was tested with 100 randomly selected students. A few students had problems setting up the interface correctly. Coding the Arduino boards was a challenge for some of the students while a few others had challenges with creating sensor nodes. Choosing the correct connectivity type to match a gateway was the most challenging for the students.
