APlus: An Intelligent Lecture Delivery System using Artificial Intelligence Learning Analytics
(IEEE, 2021-12-09) Kodagoda, C; Madampe, V; Ekanayake, R; De Silva, N; Wijesundara, M; Atapattu, P
As technology advances, new ways of teaching and learning can be discovered. Online learning platforms are able to provide easy, informative, and effective methods of delivering information since people are getting more accustomed to the use of e-learning. With the help of Artificial Intelligence, these methods can be refined to understand the users on a deeper level and provide services that are helpful and are more tailored to each user. The purpose of this project is to design an e-learning platform equipped for both educators and students. The system will be able to allow users to record/upload lecture sessions and other related study materials to the service which in return, with the use of Artificial Intelligence, try to understand the context of each lesson, segment videos, generate questions and deliver the materials to the Learner. The system will use various inputs from the Learner including video observation time, watched duration, types of videos watched, answers for questions, etc. to build a comprehensive profile of Learners. The system will use the knowledge gathered to provide services such as recommendations to the Learner, track the progress of the Learner as well as provide useful statistics of lecture materials to the Content Providers.

A Network Science-Based Approach for an Optimal Microservice Governance
(IEEE, 2020-12-10) Siriwardhana, G. S; De Silva, N; Jayasinghe, L. S; Vithanage, L; Kasthurirathna, D
In today's world of software application development, Kubernetes has emerged as one of the most effective microservice deployment technologies presently available due to its exceptional ability to deploy and orchestrate containerized microservices. However, a common issue faced in such orchestration technologies is the employment of vast arrays of disjoint monitoring solutions that fail to portray a holistic perspective on the state of microservice deployments, which consequently inhibit the creation of more optimized deployment policies. In response to this issue, this publication proposes the use of a network science-based approach to facilitate the creation of a microservice governance model that incorporates the use of dependency analysis, load prediction, centrality analysis, and resilience evaluation to effectively construct a more holistic perspective on a given microservice deployment. Furthermore, through analysis of the factors mentioned above, the research conducted, then proceeds to create an optimized deployment strategy for the deployment with the aid of a developed optimization algorithm. Analysis of results revealed the developed governance model aided through the utilization of the developed optimization algorithm proposed in this publication, proved to be quite effective in the generation of optimized microservice deployment policies.

RFID Based Theft Detection System for Automobile Parts
(IEEE, 2019-12-05) Jayakody, A; Nishshanka, S; Liyanage, N; De Silva, N; Abhayawardhana, A
Vehicle parts theft is an area of crime where less attention is being paid and weak countermeasures are being used in Sri Lanka. A survey has been conducted to find the need of an enhanced vehicle security system which can detect theft and authenticity of vehicle parts, and also to identify which vehicle parts are being commonly stolen in Colombo, Sri Lanka. In consonance with the results of the survey, it was obvious of the need for such vehicle security system. This research paper presents the design, implementation and testing of the prototype model that has been built as the proposed solution to prevent or minimize vehicle parts theft and detect the authenticity of the vehicle parts, if original parts of the vehicle were replaced with aftermarket parts without the user's consent. Theft and authenticity of vehicle parts are detected using RFID technology in the developed prototype model. To make this vehicle security system an affordable solution to the vehicle owners, a single low-cost RFID reader is used and an anti-collision mechanism is built based on TDM and signal relaying, as a cost cutting strategy to read multiple RFID tags.

A Study of the Relationship between the Job Satisfaction and Organizational Commitment of Academic Staff in Private Higher Education Institutes in Sri Lanka
(2016-12) Weerarathna, R. S; De Silva, N; Dissanayake, L. D. A. D; Kuruppu, C. L
As a developing country in Asian region, Sri Lankan higher education sector consists with government universities, private higher education institutes and semi-government universities. Irrespective of the sector, higher education institutes strongly believe about quality of their degree programmes. Higher quality of education can be achieved only by having a academic staff who are motivated, committed and satisfied to what they do. It is the usual perception that when the staff is committed to what they do, it will positively impact on their job performance, service quality and the success of the organization. Hence, it is vital to identify the importance of employees’ organizational commitment achieved through job satisfaction in private higher education sector in Sri Lanka. Therefore the primary objective of this study is to study the relationship between the job Satisfaction and organizational commitment of academic staff in private higher education institutes in Sri Lanka. The independent variable is job satisfaction and the dependent variable was organizational commitment. . This study utilized a questionnaire to collect the data which needed to achieve the research objectives. Also researchers have used standard questionnaires to measure job satisfaction which is known as Minnesota Job Satisfaction Scale and organizational commitment was measured through Allen and Mayer Organizational Commitment Scale. Current study was conducted in a natural setting where the work proceeds normally. No any artificial or contrived setting was created where none of the variables were controlled by the researchers in this study. The data was collected from the individual lecturers of five reputed academic institutions in Colombo District and unit of analysis of this study is individual.
