The Daunting Challenges of the Nigerian Electricity Supply Industry

The future state of the Nigerian Electricity Supply Industry (NESI) is seemingly beginning to look promising amid the recent change in the country’s leadership and the increase in tariffs. Nevertheless, more still needs to be done to ensure the quality, availability and reliability of electricity supply to the citizenry; thus restoring the much-needed faith in the ongoing sector reforms as the Nigerian Electricity Regulatory Commission (NERC) set about implementing the Electric Power Sector Reform Act of 2005. With the wide array of energy sources available in the country such as biomass, large and small hydro, daily solar radiation of up to 7.5kWh/m2, coal, lignite, wind, municipal solid waste (MSW), niobium, natural gas and crude oil, sufficient electricity generation using all these available sources of energy should be a given but this is not the case. Hence this paper carefully analyses each segment of the NESI and successfully identifies the root-causes of constant power outages in the country which has led to a high unreliability of supply, with a view to proffering workable solution

Development Of An SMS Based Alert Systemusing Object Oriented Design Concept

An automated lecture alert management system has been developed using java programming concept knownfor its portability. This backend system was interfaced with the GSM network through USB port of a PC and GSM modem. The desktop SMS application was developed using C# programming language. It generates updates and reminder from a time schedule stored in a database thereby making the system a time triggered application

Development of a Radio Frequency Identification Based Attendance Management Application With A Pictorial Database Framework

Radio Frequency Identification (RFID) is a technology that incorporates the use of electromagnetic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify a person, animal, or object. The main benefit of using RFID is that it does not require direct contact scanning. This paper presents an RFID attendance system, with a pictorial database framework. In this RFID system, each individual is given an RFID tag, 125 kHz in this case, which is generated by the antenna embedded in the RFID reader. The tag contains an integrated in-built circuit that stores and processes information through modulating and demodulating of the radio frequency signal that is being transmitted, and the data stored in this card is referred to as the identification/attendance of the person

Analysis Of Telecom Base Stations Powered By Solar Energy

Improved Quality of Service and cost reduction are important issues affecting the telecommunication industry. Companies such as Airtel, Glo etc believe that the solar powered cellular base stations are capable of transforming the Nigerian communication industry due to their low cost, reliability, and environmental friendliness. Currently, there are several research efforts directed on the use of solar power in the Nigerian telecommunication industry. In this paper, the importance of solar energy as a renewable energy source for cellular base stations is analyzed. Also, simulation software PVSYST6.0.7 is used to obtain an estimate of the cost of generation of solar power for cellular base stations. The simulations were carried out for the Grid-Connected and the Stand-Alone solar power systems by using Benin City, Nigeria as a case study. The PVSYST6.0.7 simulation results shows that the power generation costs for the grid connected solar powered system is less when compared to standalone solar powered system in Benin City, Nigeri

Design and Development of a University Portal for the Management of Final Year Undergraduate Projects

Processes associated with undergraduate final year projects have always been a manual process which requires a lot of paperwork and could sometimes be a cumbersome and tiring task for the personnel in charge. The manual process sometimes leads to time wasting, impeding of project work because the student carrying out the project work is not able to update the lecturer on the level of execution of the project. Also due to unavailability of a content management system or repository, duplicity of previously carried out final year projects is experienced. It could be sensed by the project supervisors or the personnel in charge that this particular project has been done but where is the proof? Where is the system that out rightly bounces the topic back when the student puts it forward or bring forth a list of projects that has keywords present in the chosen project topic? This project work therefore, eliminates or reduces the error of allowing a student to carry out a project that has been done before as well as cutting down on the cost and time required by the student to produce a quality technical report. It also helps to prevent the forgery of signatures usually experienced during the final clearance stage of the students after the conclusion of the project work. During the clearance stages, the completed stages will be noted by the computer until the final stage of the clearance stage is completed and the print button can be clicked upon by the student to bring forth the completed clearance form. In this work, we developed an intranet portal platform that can integrate all the processes above into one syste

Modelling and Analysis of Powerline Temperature Surveillance with Optisystem Simulation

A periodic variation of the index of refraction of a fiber optics is known as the Fiber Bragg Grating. It works on the principle of wavelength shifts in response to the modulation of the light source as a result of change in temperature above the reference point. This paper presents the design and analysis of Fiber Bragg Grating Sensor to measure and monitor the temperature change in powerlines for a particular range of temperature. Simulation was carried out on Optisystem to determine the peak reflectivity of the Bragg wavelength. It is seen that a change in the reflected spectrum of light is proportional to the change in temperature as shown in the FBG interrogator

IMPACT OF ICT IN OIL AND GAS EXPLORATION: A CASE STUDY

Information and Communication Technology (ICT) is of great importance to almost all aspects of oil and gas operations, from upstream to downstream operations. ICTs help to optimize oil and gas processes and thus improves the efficiency and viability of oil and gas operations. This paper presents the core areas of application of ICTs in the oil and gas industry using Nigeria’s oil and gas industry as a case stud

Efficient Item Image Retrieval System

Content based image retrieval system is a very effective means of searching and retrieving similar images from large database. This method is faster and easy to implement compare to text based image retrieval method. Ability to extract discriminative low level feature from these images and use them with appropriate classifier is factor in determining retrieval result. In this work efficient item image retrieval system is proposed. The system utilizes Haar wavelet transform, Phase Congruency and Support Vector Machine. Haar wavelet transform acted on image to form four sub-images. Texture feature is extracted from smaller image blocks from detailed bands and it was combined with shape feature from approximation band to form feature vector. Feature distance margin is achieved between query image and images in the database using Support Vector Machine (SVM). The effectiveness of the system is confirmed from output retrieval results

INVESTIGATING THE SELECTION OF A SUITABLE SLACK BUS: A CASE STUDY OF THE MULTI-GENERATING STATIONS OF THE NIGERIAN 330-KV POWER SYSTEM NETWORK

Slack bus is a bus with generating unit and used to balance the real power (P) and reactive power (Q) in the power system while performing load flow studies. This study therefore, investigated the best slack bus suitable to be used in the load flow study of the Nigerian 330-kVtransmission network with nine (9) generating stations. The method involve the load flow analysis of the existing network with Egbin, Shiroro and Kanji generating stations chosen as a slack bus at different instances and simulated using Newton-Rapson method and Gauss Seidel. This study revealed that the use of Egbin power station as a slack bus brought about the lowest power mismatch in the network. The result also indicated violation of voltages in some of the network and high reactive power los
