Publication Embargo Impact Analysis of US Dollar Index Volatility on Imports and Import Categories of Sri Lanka(IEEE, 2018-07-31) Sahabandu, R. V; Asanka, P. P. G. DThe economic liberation in 1977 resulted in drastic changes in many aspects of Sri Lanka. Considering about 1978-2015, the country yearly import demand represents over 30% share of the gross domestic product (GDP) except 1984, 2009, 2010, 2013-2015. Investigations and the studies on a countries' imports are surprisingly overlooked as there are several studies being carried out focusing only the aggregated export volume concerning the exchange rate volatility. The monthly data of Sri Lanka imports, import categories and monthly US Dollar (USD) volatility from January 2007-December 2016 were used for the analysis. This study tries to learn the impact of US Dollar Index (USDX) volatility on import demand of Sri Lanka. The Autoregressive Distributed Lag (ARDL) Approach is employed to learn long-term and short-term cointegration among the underlying variables. There exists a 95% statistically significant short-run relationship and it is identified that the import categories, Consumer Goods (CG), Intermediate Goods (IG), Investment Goods (INV), Unclassified Items (UI), None-Oil Imports (NO) have a speed of adjustment to the equilibrium (SAE) in the long-run of 17%, 36%, 23%, 23%, 25% respectively. The total imports reveal that the disequilibrium conditions will be resolved by 27% within a period of one month that is shocked due to the USDX volatility. Knowledge of the relationship between USDX fluctuation, exchange rate volatility and import volume will support to pursuit for a beneficial trade and prevent or be prepared for a much more stable situation within Sri Lanka.Publication Embargo ATHWEL: Gamification Supportive Tool for Special Educational Centers in Sri Lanka(IEEE, 2019-12-19) Kiriwaththage, P. N; Morawaka, ALearning Disability is a neurologically-based problem which involves in learning basic skills such as reading, writing and math. Intellectual Disability is characterized by below-average intelligence. Children with Intellectual Disability can do and learn new skills, but they learn them more slowly than average children of their age. Game-based learning is an effective way of getting learners actively involved in educational activities. Educating children with Intellectual Disability is a challenging process. They usually learn and progress more slowly than average children. Such children may have issues with motivation and interest in education; the use of Gamification approach becomes important as a motivational and interested affordance. A prototype desktop Gamification Supportive Tool called “ATHWELA” is proposed which operates through Assistive Technology. Assistive technology can be a device or a service that is used to increase, maintain, or improve functional capabilities of individuals with disabilities. Children with Intellectual Disability can be less interested in Mathematics, some can be not good in reading and some can be not good in writing. ATHWELA is targeting at increasing, maintaining, or improving these three points and ATHWELA can be used in special education classrooms as a tool of gratification and extrinsic motivation. Points and rewards will be presented as the motivational technique. The main objective of our research is to help children with Intellectual Disability with their primary educational skills with less effort and in an interactive way and this prototype desktop application is developed in the Sinhala language because the Sinhala is the mother-tongue of Sri Lanka. In addition, it has used Machine Learning and Image Processing techniques to improve the educational skills of children with Intellectual Disability.Publication Embargo Use of utility based interestingness measures to predict the academic performance of technology learners in Sri Lanka(IEEE, 2018-08-08) Kasthuriarachchi, K. T. S; Liyanage, S. RKnowledge extracted from educational data can be used by the educators to obtain insights about how the quality of teaching and learning must be improved, how the factors a □ ect the performance of the students and how qualified students can be trained for the industry requirements. This research focuses on classifying a knowledge based system using a set of rules. The main purpose of the study is to analyse the most influencing attributes of the students for their module performance in tertiary education in Sri Lanka. The study has gathered data about students in a reputed degree awarding institute in Sri Lanka and used three different data mining algorithms to predict the influential factors and they have been evaluated for interestingness using objective oriented utility based method. The findings of this study will positively a □ ect the future decisions about the progress of the students' performance, quality of the education process and the future of the education provider.Publication Open Access New record of Tricondyla gounellii Horn 1900 (Coleoptera, Cicindelinae), an arboreal tiger beetle from Sri Lanka(: https://www.researchgate.net/publication/336107511, 2019-09) Abeywardhana, L; Dangalle, C; Mallawarachchi, YArboreal tiger beetles belong to tribe Collyridini of order Coleoptera, family Carabidae, subfamily Cicindelinae and can be found predominantly in the tropical and subtropical regions of Asian countries mainly in forest habitat types (Toki et al., 2017). Tribe Collyridini is divided in to five genera - Collyris, Neocollyris, Protocollyris, Derocrania and Tricondyla. According to records provided by Fowler (1912) from his studies in the Fauna of British India’ five species of genus Tricondyla reside in Sri Lanka - Tricondyla femorata , Tricondyla tumidula , Tricondyla coriacea , Tricondyla nigripalpis , Tricondyla granulifera ). Three of these species, T. coriacea, T. nigripalpis, T. granulifera are endemic to the country, while the other two species also reside in India. However, the sources of this information is far outdated and unreliable and requires current investigations and revision. Thus, the present study was conducted to investigate the current species of arboreal tiger beetles of Sri Lanka, their morphology, locations, habitats and habitat preferences.Publication Embargo Android based e-Learning solution for early childhood education in Sri Lanka(IEEE, 2013-04-26) Priyankara, K. W. T. G. T; Mahawaththa, D. C; Nawinna, D. P; Jayasundara, J. M. A; Tharuka, K. D. N; Rajapaksha, S. KPreschool age is critical for a child's development. The parents of competitive society today are challenged to meet learning needs of children. They are unable to dedicate time and are not up-to-date with change of technology. The need for easy to use and effective learning aids has become vital. This research investigates how to support self-learning of modern-day preschoolers. Kids Training e-Learning System (KTeLs) is a learning tool that facilitate self learning of preschool kids. It is based on a strong theoretical foundation and allows kids to develop cognitive and psychomotor skills such as drawing, writing, recognition of numbers, basic shapes and colors and logical thinking. It incorporates a special algorithm to detect and guide the kid to write a letter in the correct direction without guidance of parents. It comes with kids-friendly navigation. The tool was designed as an Android application for tablets and was tested with a focus group. The backgrounds, sounds and colors are especially designed to maintain the attention of kids.Publication Embargo SMEs in developed and developing countries treading similar paths towards eTransformation(IEEE, 2010-07-26) Kapurubandara, M; Hol, A; Ginige, AThe global economy has become increasingly reliant on Information and Communication Technology (ICT) toolsand systems to process and exchange information. The Small and Medium Enterprises (SMEs) are yet to reap these benefits as obtaining such opportunities rests on their ability to integrate ICT into business tasks and processes. They need to transform their companies by implementing appropriate ICT in order to compete within a busy digital economy. The aim of this study was to see how SMEs from developed and developing countries follow their eTransformation journey and also to identify the differences and similarities businesses encounter in that process. Our research confirms that the eTransformation takes place as an incremental process for both groups and that the eTransformation pattern is similar in both worlds. However, we notice that in Australia, a developed country, SMEs are more aware of eTransformation and are demanded by customers and digital economy to change, where as in Sri Lanka eTransformation is still in its early stages of development.Publication Embargo E-Commerce Adoption and Appropriation by SMEs in Sri Lanka(IGI Global, 2009) Kapurubandara, M; Lawson, RAcceptance of the Internet has paved the way towards the development of virtual communities that keep increasing in the current information society making it imperative for business, especially the small and medium enterprises (SMEs) which form the backbone of any economy, to keep abreast with e-commerce and remain competitive. To stimulate and facilitate SME participation in business activities through the Internet, it is necessary, therefore, to provide clear guidance and direction with suitable models and frameworks specifically tailored for the purpose. This chapter highlights an attempt to develop a suitable framework for the e-transformation of SMEs in Sri Lanka. In the belief that new models and frameworks can help SMEs to equip themselves to better understand their current stage and identify the main barriers at each stage of the adoption process, this attempt starts with an initial exploratory study of 17 SMEs, followed by a regional survey involving 625 SMEs from various industry sectors, along with interviews with the SME intermediary organizations. The proposed model facilitates establishing the current stage of an SME with regard ICT and e-commerce sophistication using five stage variables. It also assists to determine current position with regard to barriers towards the adoption of e-commerce and helps determine the support necessary to overcome such identified barriers. The research detailed in this chapter establishes that barriers show variance when SMEs proceed to more advanced stages in the adoption process. Likewise, the necessary support required indicates a similar trend. Going further, the chapter proposes a model for adoption of e-commerce for SMEs in Sri Lanka and identifies the essential need for support while acknowledging available support. Finally, it proposes an initial framework to e-transform SMEs in developing countriesPublication Open Access Success factors for agile software development â [euro]" A Case Study from Sri Lanka(Foundation of Computer Science, 2015-01-01) Vithana, V. N; Fernando, S. G.S; Kapurubandara, MAgile software development methods provide great flexibility to adapt to changing requirements and rapidly market products. Sri Lankan software organizations too are embracing these methods to develop software products. Being an iterative an incremental software engineering methodology, agile philosophy promotes working software over comprehensive documentation and heavily relies on continuous customer collaboration throughout the life cycle of the product. Hence characteristics of the people involved with the project and their working environment plays an important role in the success of an agile project compared to any other software engineering methodology. This study investigated the factors that lead to the success of a project that adopts agile methodology in Sri Lanka. An online questionnaire was used to collect data to identify people and organizational factors that lead to project success. The sample consisted of Sri Lankan software professionals with several years of industry experience in developing projects using agile methods. According to the statistical data analysis, customer satisfaction, customer commitment, team size, corporate culture, technical competency, decision time, customer commitment and training and learning have a influence on the success of the project.
