INTRODUCTION Data science has received widespread attention in academic and industrial circles. New data science research institutes and organizations have continued to emerge on the scene, such as the Columbia University Institute for Data Sciences and Engineering and New York University Center for Data Science. The University of California at Berkeley, Columbia University, Fudan University, and other universities have launched data science courses and degree programs. Cleveland and Smith pr...
Abstract : A simple replication-based mechanism has been used to achieve high data reliability of Hadoop Distributed File System (HDFS). However, replication based mechanisms have high degree of disk storage requirement since it makes copies of full block without consideration of storage size. Studies have shown that erasure-coding mechanism can provide more storage space when used as an alternative to replication. Also, it can increase write throughput compared to replication mechanism. To i...
As it is known from time immemorial that everything in life is like the two side of a coin, there is always a positive and negative side of every phenomenon. But whether the effect is positive or negative the effects of Information Communication Technology (ICT) is far reaching and cannot be overemphasized. The Effects of ICT lens looks at how our lives have been changed, for better and for worse, by the impact of ICT. It includes both positive effects and negative effects and looks at how ...
Virtual local area network (VLAN), is a logical grouping of network users and resources connected to administratively define the operation of activated ports on a switch. The creation of VLAN is saddled with the ability to develop smaller broadcast domain within a layer-2 switching router; by assigning different ports on the switch to different sub networks. The application was a re-design project carried out on the Niger-Mills’ network to improve the operational short falls identified by t...
— Investigations have shown that interior places of the nation lacked capacity for high speed Internet usage; except the cosmopolitan sections. This article, therefore, conceptualizes a robust Broadband roadmap that can effectively deliver IP-wholesale and IP-retail services, through traffic convergence. The interconnect platforms are designed to ensure automatic re-routing of broadband traffic during link or node failure. The IP-wholesale services can be delivered to all main cities in Nig...

ABSTRACTOil and Gas sector includes the exploration, gathering, production, processing, storage, and transportation of petroleum liquids and natural gas. With the oil and gas sector fueling every aspect of our daily life, the protection of its critical infrastructure is crucial. It is known that digitally connected oil and gas operations help to improve production (General Electric, 2018). So, in order to sustain uninterrupted energy production and for quick recovery from major cyber incident...
The tumultuous increase in ATM attacks using eavesdropping, shoulder-surfing, has risen great concerns. Attackers often target the authentication stage where a customer may be entering his login information on the ATM and thus use direct observation techniques by looking over the customer's shoulder to steal his passwords. Existing authentication mechanism employs the traditional password-based authentication system which fails t...
With the maturation of digital manufacturing technologies like 3-D printing, a new paradigm is emerging of distributed manufacturing in both scientific equipment and consumer goods. Hardware released under free licenses is known as free and open source hardware (FOSH). The availability of these FOSH designs has a large value to those with access to digital manufacturing methods and particularly for scientists with needs for highly-customized low-volume production products. It is challenging t...
