SURF-FAST BASED PARTICLE FILTER TRACKING OF ARAPAIMA GIGAS

F. S. Bala*, A. A. Shafie, U. U. Bello

Invasive Alien Species (IAS) of fish has recently become issue of concern, due to their adverse ecological effect, as well as potential risk and danger to humans. Method of containment mostly employed to invasive fish without harming indigenous fish species would involve direct human effort. The involvement of humans in physical and direct containment of invasive fish species can be very tedious, ...

MODULAR MULTILEVEL CONVERTER WITH HARMONICS COMPENSATION FOR STATE-FEEDBACK CONTROLLER

A.U. Lawan*, A.Abdulkarim, I.S Madugu, A. B. Kunya, G.S. Shehu

The voltage variations among the sub-module (SM) capacitors result in harmonicssuperimposed unto the circulating current. The conventional control of the SM voltages usesa closed-loop proportional Integral (PI) controller based on carrier shifted pulse widthmodulation (CSPWM). The PI-controller provides a dc reference circulating current for thecontrol of the modular multilevel converter (MMC) mea...

IMPACT OF NUMBER OF CHANNELS ON THE CAPACITY OF SINGLE AND MULTI-CHANNEL WIRELESS NETWORKS

S. A. Babale*, D. D. Dajab, S. H. Lawan, L. U. Daura, S. G. Mohammed

Radio Frequency (RF) suffers lot of impairments and perturbations resulting in counterssuch as call drops rate, failure rate and congestion rate on one hand and beam-width, fading,shadowing and attenuation on the other hand. These factors seriously affect systemscapacity. To combat the effect of these impairments on the signal, the information can betransmitted via multiple channels by deploying m...

A CONCEPTUAL FRAMEWORK FOR PRACTICAL IMPLEMENTATION OF LI-FI FOR V2V VANET COMMUNICATION

H. Bello-Salau*, A. J. Onumanyi, B. Yahaya, A. M. Aibinu, Z. Attah, M. O. Momoh

The emergence of light fidelity (Li-Fi) has revolutionized the way information are sent froma source to destination. Despite the expensiveness of Li-Fi, it still found application in mosttime critical information transmission between a source and destination due to its fastness.Consequently, this paper presents a Li-Fi mimic approach for communicating sensed roadanomalies among vehicles in a Vehic...

ANALYSIS OF LMS DALTONIZATION ALGORITHM FOR ADJUSTING IMAGE COLOR FOR DEUTERANOPIA

Aisha Badamasi Muhammad*, Ja’afar Zubairu Maitama, Amir Bature, Zainab Yunusa

Color Blindness is a vision deficiency that leads to missing out of some colors present in animage or video. This in turn affects the lives (both personal and professional) of peoplesuffering from it. In order to limit or solve color blindness problems, digital imageprocessing algorithms for adjusting image color have been proposed in the literature.Amongst the most prevalent, RGB color contrastin...
