Development of a Bluetooth-Based Contactless Automated Attendance Capture System for Large Halls and Auditoriums

Abstract-The g Attendance capture for large populations still remains a challenge for organizations such as Schools, Universities and Event organizers. This is due to the fact that the attendance capture process is sequential requiring individual identification and autentification process. This process usually takes up a lot of time and generates a lot of inconvenience for the attendees. This process is also subject to manipulations as the most common identification model involves the use of ID cards embedded with either RFIDs or identification methods to tie the user to the card. These cards can be given to third parties for the purpose of taking the attendance. This paper presents the development of a Bluetooth based system and a local identification system for the development of a contactless identification capture system for large halls. The system identifies the user using his fingerprint. When the identification is completed, the data is transmitted to a central data base using the Bluetooth transmission technology. This system will enable a contactless capturing of the attendance in large halls resulting in a system with a very high security level and no inconvenience for the attendees

Capacity Integration into a Microgrid, a Tool for Electrical Energy Supply Cost Reduction in Nigeria- Covenant University as a Case Study

Abstract -The cost implication of running a cluster of stand-alone power generating plants was investigated using the generating capacities of the generators and consumption (load) profile obtained from a campus based substation. Analysis of the results revealed a lot of unused available capacity within the system which invariably increases the operating cost of power generation within the campus. Integrating the power generators into a microgrid was suggested where there will be a common pool of energy sources and all loads attached to the network. The proposed network model seeks to reduce power plant engagement by integrating the generating power plants into a microgrid system. To overcome the challenge of synchronization in the AC platform as the power generators are dissimilar, the network is designed to operate as a DC microgrid where the AC generating plants and loads will be interfaced by converters (rectifiers) and inverters respectively. This method reduced the unused capacity being wasted by reducing power plant engagement and consequently reducing the running cost of power generation in the campus
