Abstract

This paper gives the report of the experimental set-up to evaluate the effectiveness of Hybrid blended learning system (HBLS) in teaching mathematics among engineering students in Nigeria. A total of 1197 students was sampled. We first conducted and investigative research with questionnaire to assess the student's readiness to use of social medias networks. We discovered that 93% (1113) of the sampled population has internet enable mobile phone and they make use of facebook or WhatsApp account at least 5hrs in a week. We use both face-to-face method in the physical classroom while virtual classroom was created in facebook and WhatsApp where course content is delivered before physical class, also for after physical classroom interactions among the students and lecturers. Another questionnaire was given to the sample population to assess their learning experiences after which the exams was given to evaluate the students' performance. Exam result was compared with previous result where teaching was done through face to face method. It was discovered that about 89% (1065) of sample population had 50 and above in the collated result which is sharply defer when compared with the previous semester where only face-to-face method was adopted.

Abstract

Quality assurance in education system is paramount to the global sustainable development, therefore conventional surveillance systems that use cameras and process large amounts of data to extract features from a classroom environment may be essential. This work presents the design and implementation of automated classroom monitoring and security system with CCTV cameras and PIR sensors to monitor student's behavior and observe teacher performance during classroom activities. An active central control system and PIR sensors was designed. CCTV cameral, DVD system, and PIR sensors were networked to implementing the e-monitoring system. The control system supply power to both cameras and PIR sensor. The PIR sensors senses the movement within the monitoring area, and then activate the cameras, then the DVD system start recording the activities for online or offline view by human agent.

Keywords

CCTV, PIR Sensors, Student’s Behavior, Teacher’s Performance, Quality Assurance.

Abstract

The shortest path problem is an approach towards finding the shortest and quickest path or route from a starting point to a final destination, four major algorithms are peculiar to solving the shortest path problem. The algorithms include Dijkstra's Algorithm, Floyd-Warshall Algorithm, Bellman-Ford Algorithm and Alternative Path Algorithm. This research work is focused on the design of mobile map application for finding the shortest route from one location to another within Yaba College of Technology and its environ. The design was focused on Dijkstra's algorithm that source node as a first permanent node, and assign it 0 cost and check all neighbor nodes from the previous permanent node and calculate the cumulative cost of each neighbor nodes and make them temporary, then chooses the node with the smallest cumulative cost, and make it as a permanent node. The different nodes that lead to a particular destination were identified, the distance and time from a source to a destination is calculated using the Google map. The application then recommends the shortest and quickest route to the destination.

Abstract

In recent time the use of communication gadgets (mobile phones, laptop, desktop etc.) and service for online communication between two parties over a long distance has become sine-qua-non. Some criminal minded people are using this online communication method to deceive their prey via proxy communication where individual claiming to be discussing is not really the one. In this paper, we focus on prevention of identity impersonation attacks in an Online Communication System. Peer-peer Audio Visual Communication System is design to enhance security through online communication system by revealing the identity of the communicators and records the communication if necessary. Embedded application system was design for mobile and desktop devices for audio visual charting using modern IT devices.

Keywords

Audio Visual Communication System, Online Communication, Sybil Attacks.

Abstract

This report present the outcome of an investigative research conducted to examine the modu-operandi of academic staff union of polytechnics (ASUP) YabaTech. The investigation covered the logistics and cost implication for spreading union activities among members. It was discovered that cost of management and dissemination of information to members was at high side, also logistics problem constitutes to loss of information in transit hence cut away some members from union activities. To curtail the problem identified, we proposed the design of secure and dynamic website for spreading union activities among members and public. The proposed system was implemented using HTML5 technology, interface frameworks like Bootstrap and jquery which enables the responsive feature of the application interface. The backend was designed using PHP MYSQL. It was discovered from the evaluation of the new system that cost of managing information has reduced considerably, and logistic problems identified in the old system has become a forgotten issue.

Abstract

Computer and Internet-Based Communication Technologies aka Cybernetic Communication play important role in communication over a distance. This work gauged uses of cybernetic communication as major means of communication during COVID-19 outbreak based on measured (Social Distance, Self-Quarantine, Isolation, Lockdown) put in place by the government to curtail spreading of the disease in Nigeria. Data were randomly collected through online publication, newsprints, and telephone calls from 290 sampled population. Data Collected were discussed and analyses using Pie chart, Percentile, and Histogram as statistical tools. Findings shows that Cybernetic communication play major role to bridge the communication gaps between the Nigerian people during the outbreak of the Covid-19 outbreak as majority of Nigerians spent more hours using cybernetic tools to communicate and more money was spent on airtime and data to keep their mobile phone running during the trying period of COVID-19 rash. Majority of the sampled population spent their useful time on social medial as in Facebook, whattsapp, Instagram, YouTube and for social interactions and meetings. The implications of our findings are: majority of Nigeria may have computer linked diseases or syndrome such Sleeping Problems and others due to prolong uses of computers; the cybernetic tools (mobile phones, computer, laptop etc.) used by the infected people may be a carrier of the symptoms in the nearest future; Nigerians spent more on data and airtime credit in this trying period and it may affect their financial economy later. This work ends with proposal for roles to be played by Nigeria government and other stakeholders in cybernetic sustained communication processes for pandemic response and to prevent future outbreak of covid-19 after overcoming recent happenings, and also recommended organization strategy for workforce continuity and recovery.
