This paper looks at the role of emerging ICT on the general operations of Federal Radio Cooperation of Nigeria in achieving an objective of information decimation. This study shows that the ICT facilities have brought significant improvement to the FRCN service delivery which is important factor for growth and development in the society even though there are still some problems militating the use of ICT in the FRCN. The highest factor militating against the use of ICT is shortage of power supply followed by poor funding and lastly poor network facilities.

Researchers through high degree scalability have proposed several spatial indexing structures towards this effect. Among these indexing structures is the X-tree. The existing X-trees and its variants are designed for dynamic environment, with the capability for handling insertions and deletions. Notwithstanding, the X-tree degrades on retrieval performance as dimensionality increases and brings about poor worst-case performance than sequential scan. We propose a new X-tree packing techniques for static spatial databases which performs better in space utilization through cautious packing. This new improved structure yields two basic advantage: It reduces the space overhead of the index and produces a better response time, because the aX-tree has a higher fan-out and so the tree always ends up shorter. New model for super-node construction and effective method for optimal packing using an...

The only widely accepted way of securely and reliably authorizing electronic payment transactions is through the use of digital signatures in a public key infrastructure (PKI) framework which is computationally expensive. This paper presents an electronic payment(E-Payment) authorization system where two factor authentication (T-FA) was utilized for the authorization of payment transactions. The description approach is based on UML notation ,the functional processes are presented as use cases, the classes that make up the system structures were presented and the system was implemented on java technology with MS ASP for the web presentation and MS SQL for the DBMS. The system enables securely authorizing payment transactions using the Internet channel. Keyword:E-Payment, E-payment Security, E-payment Syste...

Spatial databases describe the fundamental representation of the object of a dataset that comes from spatial or geographic entities. A spatial database supports aspects of space and offers spatial data types in its data model and query language. The spatial or geographic referencing attributes of the objects in a spatial database permits them to be positioned within a two (2) dimensional or three (3) dimensional space. This chapter looks into the fundamentals of spatial databases and describes their basic component, operations and architecture. The study focuses on the data models, query Language, query processing, indexes and query optimization of a spatial databases that approves spatial databases as a necessary tool for data storage and retrieval for multidimensional data of high dimensional spaces.

The increased use of electronic based learning systems has also amplified the amount of data available and more readily accessible for decisions making. The improvements in the data mining algorithms also make analysis of this volume of data easier. In recent times, there has been increased interest and research in the field of Educational Data Mining [1]. With the increasing research interests in the use of data mining in educational system and with the emerging field of Educational Data mining, which is concerned with developing methods that discover knowledge from data originating from educational Institutes [2]. These data can be collected from different educational system where the data reside in their databases. The data can be personal records or academic records that can be used to understand students' learning behavior, to assist instructors, in ...

The features of dataset used in training a machine learning model have a huge influence on the performance of the model. In this paper, we present two feature selection techniques; a filter approach; the correlation based feature selection using best fit as search method and wrapper approach. these were used to illustrate the importance of feature subset selection for classifying students’ performance. The reduced feature subset obtained is then tested using the Naïve Bayes supervised classification algorithm. Experimental results show that the feature subsets selected by wrapper resulted in marginal improvement over the reduced subset from CFS filter.
