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, which is characterized by the review of previous studies that have proposed data aggregation......

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 totalTime from the other five. The resultant data showed that the crawler functions deployed in this study performed 0.6 seconds quicker than those already available in the five price comparison websites which were used as case study.

ABSTRACT: Blended learning approach combines the best of both the face to face classroom (F2F) and online learning experience.This provides a complete and enriched learning experience to the learners. This study investigated the impact of blending wiki classroom with face to face (F2F) classroom on students' academic performance in the Faculty of Education, University of Port Harcourt. Rivers State, Nigeria. A 2-group pre-test post-test quasi experimental design was adopted. Two objectives, two research questions and two hypotheses guided the study. The population comprised 100 - level undergraduate students from eight departments in the Faculty. Simple random sampling technique was used to select two departments, and all one hundred and sixty(160) students from the......

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 using descriptive and inferential statistics such as percentage distribution, mean and standard deviation as well as regression analysis. The findings revealed an overall moderate extent of ICT investments in the Niger Delta region of Nigeria, it shows that ICT investment was a significant predictor of Job Creation (F 1, 306 = 171.637.....

ABSTRACT: English learning in Nigeria has become imperative and its continuous learning cannot be waved, since it is the official language in Nigeria and an international language for communication. Despite the importance of English language, student's performance in English language in Nigerian secondary institutions has been discouraging. Research has shown that vocabulary is the most important element of any language learning including English language. This paper implemented a mobile gamification learning system for motivating learners to continue learning English vocabularies effectively on mobile devices. The system was evaluated, through an online survey, which was completed by 71 participants with different English vocabulary level abilities. Experimental results revealed that the developed system significantly improve learner's English vocabulary abilities and learning interests..
