Developing a framework to adapt FOSS for IT companies in Sri Lanka
(University of Kelaniya, 2011) Nayanajith, B.; Thelijjagoda, S.
With the introduction of intellectual property rights and copyright laws, most of the software consumers have been facing major issues with increased cost; due to purchase of expensive proprietary software. As an alternative, free and open source software (FOSS) has become increasingly popular around the world, particularly in the government sector. However, in Sri Lanka, most of the computer users are still reluctant to use the Open Source Operating Systems and Software, mainly due to lack of awareness and knowledge in this area. Low software costs, growing local software development industry and bridging the digital divide are the reason for FOSS to be seen as a viable option. As a matter of fact, IT companies have the option to reduce the IT Operational cost by 50%, by switching to FOSS. However, most of the IT sector employees and organizations are reluctant to switch to FOSS due to many disasters faced by some companies during the phase of transition. It is noted that various challenges and obstacles hamper the full FOSS implementation within the IT companies. The contribution of this research paper is on FOSS expansion framework, which is proposed as a possible solution to migrate existing Software environment to FOSS successfully. There are five specific objectives covered in this research: identify the most widely used operating systems and software in Sri Lankan IT sector, the reasons behind their wide applications, employee readiness for FOSS, create framework for migration to FOSS and test the framework. In order to create this framework we have extensively re-sorted primary and secondary data collection methods, including findings of prior literature reviews, by building up questionnaires and surveys focused on general IT sector as the target audience. The findings from the participants will be helpful in identifying the gaps between the resource base provided by the IT sector and the employees in respective IT companies. By doing so, it would generate a transparent environment with an approach of rectifying possible deadlocks in FOSS migration.
An exploratory study on how technology makes changes in railway transportation in Sri Lanka
(University of Kelaniya, 2011) Halpita, A.S.; Thelijjagoda, S.
“Sri Lanka Railway” is one of the government departments of the Democratic Socialist Republic of Sri Lanka. Sri Lanka Government Railway operates the country‟s railway network which includes 1449 kilometers of track and 333 stations. Under the prevailing situation, the railway transports over 86 million passengers and 1million tons of goods per year. After analyzing the current railway system through questionnaires and interviews with passengers, Station Masters, and observations, it was clear that most of the work related to Sri Lanka Railway service is done manually. Most of the passengers are not satisfied with the services rendered by the present public railway transportation system and they are compelled to travel by roads which result in congestion during peak hours. Although the number of passengers using the railway is increasing, and the quantity of goods transported by the railway is becoming higher year by year, government railway seems to be running at a loss. There are three specific objectives of this research: identifying the drawbacks of the existing railway service and resolving them by applying technology, providing suggestions to improve the public sector transportation by applying technology, providing passengers a quality service as well as streamlining the work procedure and identifying the ways which can bring additional revenue to the Railway Department by applying technology. By this research study, the researcher was able to find the drawbacks of the current railway system and the ways in which the railway service could be improved to satisfy the challenging market environment. The researcher also found some solutions like on-line tickets, unreserved ticketing system, automatic ticket machines, passenger reservation system, time table system, railway freight transportation, advanced cargo information system, short message service, railway signal and control system, railway smartcard, railway tour package, passenger information system, customer information system, railway yield management system, automatic ticket gates, railway CRM, railway facilities, tailor made reporting system for Station Masters, railway announcement system, etc.

With the advancement of the technology the transition from forum and blog-based Internet communication among users to social networking sites such as Facebook and Twitter, allow users to create and share content related to different subjects, which expose their activities feelings and opinions. The purpose of this research article is to provide a web application in order to detect one's personality using linguistic feature analysis. The personality of a person is classified according to Eysenck’s Three Factor model including Extrovert - Introvert, Neuroticism - Emotional Stability, and Psychoticism - Tender. The proposed technique is based on ontology based text classification, linguistic feature-vector matrix using LIWC (Linguistic Inquiry and Word Count) features and semantic analysis using supervised machine learning algorithm named Naïve Bayes. The extracted data provides extraordinary information about the personality of a person under human feelings and social interaction. It conveys who the users are and what their qualities are. This is vital for the areas such as HR management systems, R&D Psychologists and all the other API users. Considering HR management sector this would be an advantage in recruiting process, salary increments and providing allowances. R&D Psychologists will gain the advantage of the dynamic ontology to make their research result in a more efficient manner. System will be exposed as an API for universities, sports and social clubs when recruiting individuals to those organizations. According to the test results the proposed system is in an accuracy level of 91% when tested with a real world questionnaire based application. Experiments have been carried out comparing with a real world personality detection questionnaire based system and results demonstrate that the proposed technique can detect the personality of a person with acceptable accuracy and a speed.
