    Conceptual Design and Turbine Selection for a Micro Hydropower System Using Multi-Criteria Analysis
    (Nigerian Journal of Engineering, 2023) Jimada-Ojuolape, Bilkisu; Balogun, Monsurat; Adesina, Lambe
    Nigeria has grappled with a persistent electricity supply challenge characterized by surging demand, inadequate maintenance of power generation infrastructure, and a host of other issues. This ongoing predicament has given rise to frequent power outages, compelling citizens to resort to expensive alternatives like petrol and diesel generators. Moreover, a substantial number of Nigerian households rely on motorised boreholes for their water supply. Considering these circumstances, this study proposes an innovative solution in the form of a micro hydropower system that harnesses the existing tank-borehole setups within homes to generate electricity. The primary objective of this research is to define the specifications of the central subsystem, namely the turbine, by employing the multi-criteria analysis method, thereby facilitating the practical implementation of the proposed energy generation scheme. In particular, this study delves into an evaluation of two turbine options: Pelton and crossflow turbines. The results of the analysis revealed that the crossflow turbine emerges as the most suitable choice for this application, leading to the exclusion of other turbine alternatives such as the Francis and Turgo turbines.

    Development of a GSM based Vehicle Demobilizer and Tracking System
    (ABUAD Journal of Engineering Research and Development (AJERD), 2023) Jimada-Ojuolape, Bilkisu; Spencer, Oluwafunto; Balogun, Monsurat
    Vehicle hijacking remains a pervasive global issue, posing heightened risks, especially when owners face armed hijackers. Concurrently, the disposal of old mobile phones contributes significantly to the escalating electronic waste (e-waste) challenge, emphasizing the imperative of responsible recycling practices. Addressing these concerns, this paper introduces a GSM-based vehicle demobilizer and tracking system, utilizing a cost-effective mobile phone connected to the device through a SIM card and operating with an NE 555 timer IC in bistable mode. In the event of a hijacking, a call to the mobile phone triggers the device, halting the vehicle. In the prototype design presented in this paper, the result of the output is represented by an LED to show that the circuitry actually works. When the device was tested, the LED illuminated when a call was placed to the mobile phone connected to the device which signifies that the circuit works and can achieve its purpose. The resulting design also shows that the vehicle owner can prevent his car from being stolen away even after it has been hijacked without self-endangerment and within a short time frame.
