ABSTRACT: A lot has been said about different techniques of aggregating data in a smart grid communications. What is yet to be extensively explored is the concept of smart grid application in Nigeria's power sector. The smart grid can exchange data about current electricity status, pricing data and control commands in real-time. Due to these specific characteristics, the process of electricity's generation, transmission and distribution in the smart grid environment can be managed efficiently and reliably. However, smart grid technology may not be right for all power networks due to requirement for substantial resources. This work has studied the data aggregation scheme in smart grid communication........

ABSTRACT: This paper examined the difficulty in getting suitable and frequently updated prices for goods while shopping on e-commerce websites with the aid of price comparison websites. The study proposed to develop a price comparison search engine for e-commerce websites that will be faster, and possess a dynamic database frequently updated with prices of goods. This process is online-based, and the prices on the labels of displayed results of goods are hyper-linked to websites of different merchants who have these goods on their websites up for sale. Five price comparison websites were used as case study. The Representational State Transfer (REST) API was used to carry out search and time efficiency analysis of two goods across the five price comparison websites. This analysis was also carried out on the enhanced price comparison website as well with its own distinctive properties that differentiated its queryTime and..........

ABSTRACT: The advent of ICT has profoundly changed almost all aspects of human society. It is central to how people communicate, interact, make decisions and do business including the way governments operate and deliver services. This study examined the interaction between Information and Communication Technology (ICT) investment and job creation in the Niger Delta Development Commission (NDDC), Nigeria. The study adopted the survey research design. 440 out of the population of 879 employees of the commission was used for the study. Data analysis was done.......

ABSTRACT: Students' management information in Chukwuemeka Odumegwu Ojukwu University (COOU), Anambra State, Nigeria is carried out manually. Students are restricted to so many online educational activities because of the current procedure of information management. Students do not have educational interactive platforms where they interact with their lecturers pertaining to a course; lecturers cannot give assignments online and get feedback unless it is done through a social network or private electronic mail. Students' parents or guardians find it difficult to interact with their ward's lecturers because of the manual method. This necessitated an urgent need to develop a system that manages student information online. It is then the objectives of this paper: to develop a centralized.......

ABSTRACT: With the development of the telecommunication technologies and the big market size of telecom products has given rise to interconnect bypass fraud. Interconnect fraud is a bypass fraud that occurs when international traffic that should be routed through a legitimate international gateway is routed to bypass those gateways using voice over internet protocol VOIP through the Internet and terminated via Simboxes as local calls. In this paper, we examined the framework and issues associated with this type of fraud and identified that the Simbox bypass fraud has become a challenging threat to telecom companies in some parts of Africa and Asia. In grappling with the challenges.......

ABSTRACT: Mixed Reality is an upcoming domain that focuses on enhancing the user experience to become more interactive with Virtual Reality. Hand is a part of body that allows human to touch and feel different things. VR glove is the most efficient and newest tool for a user to interact with a virtual object. VR glove is basically providing input to the Virtual World as a Virtual Object controlled by user. From the many applications of Mixed reality, a game is the best application to efficiently display the use of VR Glove. Arduino Uno connected with Flex sensors and Accelerometer gives input to the Processing IDE which acts as translator to the game, and game components act as they are provided with Keyboard input. This implementation of VR glove can further be developed to interact with various Virtual realities and Augmented realities dynamically such that the user feels as if he or she is inside the VR or AR..
