Publication Open Access A study of factors affecting the exports of the garment industry in sri lanka(Faculty of Graduate Studies and Research, 2017-01-26) Abeynanda, H.K.Since the export of textiles and apparel products is one of the biggest industries in Sri Lanka, and one which plays a key role in advancing the country's economy, this paper examines the main factors affecting the exports of the garment industry in Sri Lanka. After detailed analysis of the Sri Lankan garment industry, garment exports by direct competitors to the United States and the European Union, Inflation rate, Foreign Exchange rate, Generalised System of Preferences Plus scheme, wage of workers, number of unskilled migrants, tsunami disaster have been considered in this study to identify the main factors which influence the exports of the garment industry. After identifying the main factors, this paper aims to develop a factor model to forecast the garment exports of Sri Lanka. For this purpose this paper has used MINITAB and SPSS as main statistical software.Publication Embargo Relationship between Refractive Index and Compositions of Building Windows Non Float Processed Glasses(Faculty of Humanities and Sciences,SLIIT, 2021-09-25) Guruge, M. L; Edirisinghe, P. MRefractive index is one of the physiochemical properties of substances which is mostly used in optical sciences and provides very important information about the behavior of ray of light in various materials. This study was conducted to identify highly associated compositions of building windows non float processed glasses with refractive index and to develop a linear model to represent such relationships. Results of this study will provide a clear indication on how rays of light behave when passing through building windows non float processed glasses according to its composition. For compositions of glass, it was considered elements contained in corresponding oxide other than oxide type. A multiple linear regression model fitted for the data found that only sodium (Na), aluminum (Al), silicon (Si) and calcium (Ca) are highly associated with refractive index of building windows non float processed glasses. There was a strong positive linear relationship between refractive index and calcium (Ca) while a moderately strong negative linear relationship between refractive index and silicon (Si) for building windows’ non float processed glasses. Both sodium (Si) and aluminum (Al) had weak negative linear relationships with refractive index.
