    Application of Inverse method to Reconstruct the form of Pulse During Impulsive damage to Pipelines
    (International Engineering Conference (IEC), 2015) O. A. Olugboji; J. Hale; J. Y. Jiya; C. K. Jack
    Petroleum pipelines damages if untimely detected, poses a tremendous challenge to the oil sector of an economy as it causes oil spillage, theft or explosion of the petroleum products while on transit. It is against this backlash an inverse pulse propagation method for reconstructing the form of pulse generated during pipeline defects was devised and presented in this paper. Inverse problem occurs in several branches of science and engineering. It involves the determination of the parameters of a model that describes or explains a set of observed data .This work deals with an inversion technique that was developed to reconstruct the form of a pulse after it has been propagated along a pipe. To test the suitability of the developed technique, a mathematical model was developed. The theoretical model was validated by experiment using a developed pipeline system. The experimental test rig comprises of a flexible hose pipe 23m long and 19mm diameter with four pressure sensors distributed along the pipeline and connected to the data acquisition system. Static and flowing air in the pipeline were use in the experimental test to validate the developed inverse technique model. The inverse method showed a close relationship to the original pulse.

    Event Reconstruction by Digital Filtering
    (Horizon Research Publishing. Advances in Signal Processing, 2013) O. A. Olugboji; J. Y. Jiya; J. M. Hale
    This work deals with a digital filtering technique that was developed to reconstruct a pulse after it has propagated along a pipe; a complex pulse that is progressively distorted. The technique developed makes use of the theory of digital filtering used in communications to remove distortion in long telephone links.

    Design and Fabrication of Rice De-Stoning Machine
    (Food Science and Technology, 2014) O. A. Olugboji; J. Y. Jiya
    This work aims at meeting the ever increasing demands of quality rice, avoiding losses and improving the income of local farmers. Mild steel was used in the construction of the machine. Standard equations were used to determine the dimension of the parts. The machine is driven by a 1Hp electric motor with 688.17 W required power. The machine has a capacity of 47.39 Kg/hr and an efficiency of 82.47 %

    Design, Fabrication and Testing Of a Motorized Paper Perforation Machine
    (International Journal of scientific research and management (IJSRM), 2015) J. Y. Jiya; M. S. Abolarin; O. A. Olugboji; R. I. Ngoffia; C. K. Ajani
    This is concern with design and fabrication of a powered paper perforating machine with efficiency and less cost for bindery department in printing industries. It is a machine that will compete favorably with the manually operated ones and reduce human efforts with minimum time consumption. It perforates up to 15 sheets of paper at each stroke and is powered by a horse power electric motor whose rotational motion is converted to a reciprocating motion in the perforation pin by the principle of eccentricity.
