ABSTRACT This research work is concerned with the detection, analysis and fixing of software bugs. The objective of this work was to identify software development process with a focus of identifying cost effective methods of developing and managing software systems by introducing a post-deployment debugging approach which helps track software’s stability and at same time serve as a software bug-data repository. To achieve this objective, a web-based application –BugTracker was developed t...
ABSTRACT Statistical, analytical and numerical methods have been used to develop a model for phenomenology and dynamical evolution of Compact Steep Spectrum (CSS) sources through the ambient medium of density, e n , within a characteristic time, T . Results show that the empirical relation between spectral turnover, n p , and D implies that 0.34 n p e ~ n , suggesting that the spectral turnover constitutes a characteristic signature of dense gases around CSS sources. However, since the charac...

ABSTRACT The rocks and soils underlying Lambata-Minna and Minna-Bida roads in central Nigeria were mapped with the view to determine their impact on the stability of the roads underlain by them. Vertical electrical sounding was done along the roads to determine the soil profile of the roads and statistics of the roads utilization was also done to infer if the roads are overused by vehicles. The geophysical studies revealed that the soil profiles of the two roads are composed of laterite, sand...
ABSTRACT Human Resource (HR) unit is a vital department in any institution of higher learning. The unit manages the staff welfare, recruits new staff and keep track of their records until retirement. The unit is also responsible for adequate dissemination of information through official memo and online communication to the entire stake holders of the institutions and beyond. The main objective of this study was to introduce a substantial improvement to the existing website that was been used ...
ABSTRACT The purpose of this work was to examine the patterns and determinants of fertility in Nsukka region, Enugu State, Nigeria. This was necessarily because most fertility studies across the nation lay emphasis on single or selected determinants, and using the findings to make recommendations on generalized terms which may not be applicable in different parts of the country. The data for this work was generated from questionnaire survey administered to 840 women of the reproductive age co...
Abstract CT scan is one of the most valuable tools used in the centers of modern health care and are accompanied by radiation dose greater than that of the normal radiographic and must be therefore use carefully to protect patients from radiation. The aim of this study to compare between radiation dose and image quality and to compare between CT brain protocols and radiation dose . Random samples consist of 30 patients who underwent CT brain examination. The patients data registered(age, gend...
ABSTRACT The Nanka Sand (~ocene, Ypresian Stage) is one of the several lithostratigraphic units comprising the lithic fill of the Anambra Basin, southeastern Nigeria. Its unitstratotype has been selected from a system of gullies in the Nanka town. Here the unit is 305 metres thick and is underlain by the Imo Shale and, farther southwest, overlain by the Ogwashi-Asaba Formation. The stratigraphic column may be divided into four cross-bedded and burrowed tabular sand subunits ranging from 50 to...
ABSTRACT We have modelled an open channel flow through a porous media (River). In the model, we considered water as an incompressible fluid; the flow as steady and uniform; the system is assumed to be isothermal and the flow, also a laminar flow. We have solved the resulting equation using analytical method. By some mathematical operations, the momentum partial differential equation (PDE) was reduced to ordinary differential equation (ODE) and the resulting equations are solved analytically u...
ABSTRACT The majority of software development organizations all over the world are small enterprises. Successful implementation of SPI methodologies in small software enterprises (SEs) is generally not possible because such organizations are not capable of investing the cost of implementing these programs and limited resources. Software Process Improvement (SPI) activities have been reported to result in remarkable improvements in the quality of software, reduced time to market and increased ...
ABSTRACT Petrophysical evaluation and 3D seismic interpretation were carried out on the hydrocarbon bearing reservoirs of Stroh field with the aim of maximizing the benefits of petrophysical evaluation and structural interpretation in the production and development of hydrocarbon in the reservoir of the ‘Stroh field’ in Niger Delta. Eight hydrocarbon bearing reservoirs – sands ST1, ST3, ST6, ST7, ST8, ST11, ST13 and ST14 were identified from well logs and correlated across six Stroh wel...
ABSTRACT The aim of this project was to develop a web-based system that will contain all the information about the private sector assets for tax assessment. The objective was to register and assess all the assets of the entire private sectors establishment in a particular area for tax payment. These assets include: land, heavy equipment, light equipment, motor/vehicle, residential building, commercial building, and industrial building etc. The system will carry out tax assessment of the asset...
ABSTRACT Two main geological formations outcrop in the area which is within latitudes 6"45'N-7"00tN and longitudes 7O15'E - 70301E, being part of the Anambra basin of southeast Nigeria. These are the Ajalli Sandstone that is of Middle Maastrichtian age covering most of the area and the Nsukka Formation of Upper Maastrichtian age that is less prominent and overlies the Ajalli Sandstone. These two formations belong to the same hydrostratigraphic unit and give rise to thick and extensive water t...
ABSTRACT In this work, the seven-factor central composite design () is studied in respect of a pair of missing values using the minimax loss criterion. It was observed empirically that seven-factor central composite design with k = 7 , = 128 f n , = 14 a n , = 3 c n and n = 145 is robust at a = 2.6 and variance robust at a = 2.45. We also observed that the loss effect of missing a pair of factorial points is a decreasing function of increasing a , while the loss effect of a pair of axial poin...
For many years to. come, the oil and gas industry in Nigeria will continue to play a mostimportant role in the economy of the country. The prospects for meeting up with an oil reserve base target of 50 billion barrels by the year 2010 as set in the country's Vision 2010 are quite good. The country's deep offshore from all indications will continue to be a beehive of activities for many years to come. However, a lot of the anticipated success will depend in real terms on our abi'lity to cope s...
