An alternate method of absolute value
The automatic means of assessment has proven to be the best solution to the process of selecting qualified prospective candidates among the growing population of candidates seeking admission into tertiary institutions and also evaluation of large population of students in the higher institutions in Nigeria. CBT (computer-based testing) is the automatic evaluation or assessment by which knowledge of students or candidates are measured or tested. It is in this regard that the Joint Admission a...
Logistic regression model deals with the relationship that exists between a dependent variable and one or more independent variables. It provides a method for modeling a binary response variable, which takes values 1 and 0. Further, Logistic regression is useful for situations in which you want to be able to predict the presence or absence of a characteristic or outcome based on values of a set of predictor variables. It is similar to a linear regression model but is suited to models where th...
The Hamiltonian approach for constrained optimization is indeed a useful tool in the hands of the economists, scientists and statisticians who applied it in the modelling of optimization problems. It can be noted that the treatise in this research work is an eye opener for a better understanding, application and utilization of the method as we exploit its vitality to solving optimization problems. Though, the approach seems to be a derived approach from existed ones but also intensified a g...
Artificial Neural Networks have proven to be very useful in areas that concern data mining. This research project borders on the use of kohenen self-Organising Map, a neural network based unsupervised, competitive learning algorithm that can seperate a given dataset of customers and their prefences into groups known as clusters.
Results Computation in Higher Institutions using PHP, HTML, CSS, MYSQL Introduction A student’s result is the criteria for the measurement of the student’s capability in terms of academic work in the school. It is also used to measure a student’s capability in each course offered by the student. Without an adequate results computation system, the aim for which results are produced may not be achieved, because the slightest mistake made during the process might lead to a very big problem...

Alpha-amylases are starch degrading enzymes and their activities have been found to be the major change that occurs in the ripening of bananas and plantains. This study was designed to basically develop a simple spectrophotometric method to monitor some of the biochemical processes involved in the ripening of Giant horned plantain (Apantu), French horned plantain (Apem) and local banana (Abibifo mpua).The pericarp from five ripening stages was collected and alpha amylases were extracted with ...
Abstract DNA, the genetic code of life itself has been the molecule of this century and certainly for the next one. The future of DNA manipulation is speed, automation and miniaturization. Perhaps it will not be good enough to play games or surf the web, things traditional computers are good at, but it certainly might be used in the study of logic, encryption, genetic programming and algorithms, automata and lots of other things that haven’t even been invented yet!! Therefore, it w...
Abstract The effect of Shea butter rich diet on gentamicin induced nephrotoxicity in rats was determined. Thirty (30) male and female albino rats grouped into 6 (normal, negative, positive, 10%, 20% and 30% Shea butter rich diet groups respectively) of 5 rats each were used for the study. Phytochemical analysis was carried out on the Shea butter used for this study which revealed the presence of saponin, tannin, alkaloid, terpenoid, flavonoid, and reducing sugar, while coumarin was absent. ...
This paper is aimed at using up-hole method of seismic refraction survey to investigate the thickness of the weathering layer as well as the velocity of seismic waves through the layer. The first events to arrive at the geophones on a refraction profile had travelled by refraction along the top of the high speed zone just below the weathering layer. Using the time- offset curves of the first arrivals for shots from different charge depths; the thickness of the weathering layer was calculated ...
In this study, digital format data comprising of aeromagnetic and remotely sensed (Landsat ETM+7) data were used for structural interpretation of the Awgu area in Enugu State, southeastern part of Nigeria, predominantly underlain by sedimentary rocks. Aeromagnetic data were analyzed using the Oasis Montaj 7.5 software and interpretation was carried out using the vertical and horizontal gradients, analytical signal, reduction to pole, tilt depth as well as Euler deconvolution. The total magnet...
Magnetic study over South Eastern Nigeria was performed as part of a multi-technique geophysical investigation. Various magnetic data enhancement procedures such as, qualitative (second vertical derivative, total horizontal derivative, analytic signal, theta map, tilt derivative, total horizontal derivative of tilt derivative and horizontal tilt angle) and quantitative (Werner and Euler deconvolutions) interpretation techniques were employed to determine their effectiveness in characte...
Amplitude variation with offset (AVO) analysis was carried out on Konga oil field, an onshore oil field in the Niger Delta, Southeastern Nigeria. The study consisted of forward modeling from rock parameters measured from well logs and AVO analysis of events on pre-stack time migrated 3D seismic gathers. Forward modeling predicted specific AVO behaviour of anomalous reservoir sands in the field. Density, compressional and shear wave velocity logs, combined with a wavelet extracted from...
Abstract Municipal solid waste disposal sites can be sources of groundwater contamination and the contamination problems are more likely to occur in humid areas, where the moisture available exceeds the ability of the waste pile absorb water. 2-D resistivity imaging has frequently been used in the subsurface pollution studies. The method maps the distribution of resistivity of subsurface materials. The 2-D resistivity image provides general information on subsurface stratification of buried w...
