ABSTRACT A simple method is described for the construction of a set of orthogonal polynomials for any case where the proportions of observations follow a binomial distribution. The least squares equation which fits the data is determined using the properties of orthogonal polynomials and the analysis of variance technique. The computations required for determining orthogonal […]
ABSTRACT This paper presents the design and construction of a small loop antenna which has been used in the reception of standard time and frequency signals in the Very Low Frequency (VLF) range. The loop antenna was used, along with other components of a receiver system, to receive some of the transmissions. Some stations of […]
ABSTRACT The study area lies in the rainforest belt of sourtheastern Nigeria, an area of about 15, 600Km2, devastated by acute Fourier transformation of aeromagnetic anomaly data of Calabar Flank from space domain to frequency domain yielded a method for source depth determination. From the analysis of the magnetic data, progressively deeper sources correspond to […]
ABSTRACT The study area lies in the rainforest belt of sourtheastern Nigeria, an area of about 15, 600Km2, devastated by acute and chronic gully erosion. It is underlain by a sequence of Creaceous to Recent sedimentary rocks, which are dominantly shally, tending formations towards the top. The region is characterized by steep slopes, complex geological […]
ABSTRACT There has been persistent hue and cry against the rate at which our environment is being abused. This outcry of alarm is global in nature which demands sincere comments and contributions from well meaning individuals towards achieving possible remedies. This paper examines how poverty is seen to be one of the greatest factors inducing […]
ABSTRACT This work is centered on the deductive enterprise model (DEM) as a better approach to enterprise modeling and integration of any information system that will be able to deduce answers to questions that one would normally assume can be answered if one has a commonsense understanding of the enterprise. Review of other models is […]
ABSTRACT The solutions of linear programming problems using super convergent line series’ approach is considered in this paper. It is found that the results compare reasonably well with values obtained using simplex method. An algorithm known as line search exchange algorithm is used. Download Full Article
ABSTRACT We consider estimation of the mean and variance in two-stage sampling of equal clusters with large sizes. The subgroups of respondents in the different clusters are assumed to be equal. An extension of the sample mean to the nonoresponse group is obtained by combining means of subsamples of nonrespondents in each of the selected […]
ABSTRACT An algorithm that is designed essentially to find a path of minimum length between two specified vertices of a connected weighted graph is known as shortest path algorithm. The algorithm for solving a class of these kind of problem was developed by E. W. Dijkstra in 1959. The fundamental aim of this research paper […]
ABSTRACT A new numerical method of solving linear delay differential equations based on the concept of step-by-step approximation of the system equation is formulated. The solution is presented in the of nth finite series of kth order for n + 1-subinterval. Its application to numerical problems confirmed its suitability. Download Full Article
