Skilling Requirements in Textiles: Technical Training and Its Trainers-Sri Lanka in Perspective  [PDF]
Rohana U. Kuruppu
Journal of Textile Science and Technology (JTST) , 2018, DOI: 10.4236/jtst.2018.44007
Abstract: The textile and clothing industry has become very competitive in the world over. There are many players in the industry. The most prominent player is China. Recent statistics reveal that China continue to be the world’s largest textile and clothing producer in 2016 (Textiles outlook, 2017). China’s major export markets are EU, USA and Japan. However, rising labour costs and production costs of China will shift production to lower cost suppliers. This will give South Asia and South-East Asia an opportunity to capitalize in their exports. The question is, can these regions in Asia take this challenge? To overcome the challenges, they must be ready with highly skilled manpower. The Tertiary and Vocational Educational Training system across Asian region must be geared to take this challenge of training the new recruits. Can these countries have adequate numbers of skilled, effective and experienced trainers to train the new recruits? Qualified trainers may be in short supply. Then, how quickly can these trainers be made available for training? Half-baked trainers would turn half-baked workers that will not give right condition to meet the future challenges. A recent study by the author has revealed that there are not enough qualified trainers to impart knowledge and skill for those in the textile and clothing industry in Sri Lanka. This can be the case across Asia. It is time that responsible professionals in the training industry should consider about trainers if they are to launch a massive skilling project to meet requirements of the textile/clothing industry. Skilling the trainers must be a priority. It will be interesting to note that there is a mismatch between trainees and training courses. Also, students are not attracted to training courses. So, there is a concern about who should be trained and are they available?
High Speed Motion Tracking for Weightlifting based on Correlation Coefficient Template Matching
Gihan Kuruppu,S. R. Kodituwakku,U. A. J. Pinidiyaarachchi
International Journal of Soft Computing & Engineering , 2013,
Abstract: Tracking of motion in weightlifting is a challenging task. This paper presents a method for tracking Weightlifting bar movement of an athlete. The proposed method uses three different template creation techniques for tracking and applies Wilcoxon Signed rank test to evaluate the results. The method was tested with normally captured data (30fps) and data captured in slow motion (100fps) separately. For the normally captured data, combined dynamic templates method has the highest accuracy of 95% in tracking the trajectory. For slow motion data Wilcoxon Signed Rank generated equal results for all three template creation methods.
The Impact of Adoption of Flexible Manufacturing Technology on Price Cost Margin of Malaysian Manufacturing Industry  [PDF]
Don Ajith Rohana Dolage, Abu Bakar Sade
Technology and Investment (TI) , 2012, DOI: 10.4236/ti.2012.31005
Abstract: This paper explores the impact of the adoption of Flexible Manufacturing Technology (FMT) on the Malaysian Manu-facturing Industry. The Principal Component Analysis has been adopted to extract the most appropriate underlying dimensions of FMT to use in place of the eight FMT variables owing to the potential multicollinearity. The study has been conducted within FMT intensively adopted 16 three-digit industries that encompass 50 five-digit industries cover-ing the years 2000-2005. The results obtained from the two scenarios, one, including the industry fixed effects dummy variables and the other without these, are contrasted. It is established that the model that included the industry fixed effect dummy variables has a greater explanatory power. The two principal components that account for the greater variation in FMT show positive and moderately significant relationship with PCM. The study provides sufficient evi-dence to conclude that FMT has a direct and moderately significant relationship with PCM.
A Frontier Approach to Measuring Impact of Adoption of Flexible Manufacturing Technology on Technical Efficiency of Malaysian Manufacturing Industry  [PDF]
Don Ajith Rohana Dolage, Abu Bakar Sade
Technology and Investment (TI) , 2012, DOI: 10.4236/ti.2012.34037
Abstract: This paper examines the impact of the adoption of Flexible Manufacturing Technology (FMT) on the Technical Efficiency of Malaysia Manufacturing Industry. Owing to the potential multicollinearity, the Principal Component Analysis has been adopted to extract the most appropriate underlying dimensions of FMT in an effort to substitute the eight FMT variables. The study has been conducted within FMT intensively adopted 16 three-digit industries that encompass 50 five-digit industries covering the years 2000-2005. The results obtained from the two situations, one, including the industry fixed effects dummy variables and the other without these, are contrasted. It is found that the model that included the industry fixed effect dummy variables possesses a greater explanatory power. The two principal components that account for the greater variation in FMT show positive and moderately significant relationship with TE. The study concludes with sufficient evidence that FMT has a direct and moderately significant relationship with TE.
Life Can’t Be Any Easier than This—Introduction of the Portable and Disposable V.A.C. Machines  [PDF]
Muhammad Ali Hussain, Lalindra Kuruppu, Hardeep Jhattu, Charlotte Ying, Simon Wharton
Modern Plastic Surgery (MPS) , 2012, DOI: 10.4236/mps.2012.22006
Abstract: The application of controlled levels of negative pressure on to a wound has been shown to accelerate evacuation of dead cells, debris and fluid which eventually encourages wound healing in a verity of surgical wounds. Vacuum Assisted Closure (V.A.C.) therapy—KCI Medical Limited, the terminology by which this is widely known, became popular, especially among the plastic surgery professionals in America and soon gained recognition worldwide. It is now widely used in the UK to manage and assist healing in a wide variety of wounds. Although KCI’s V.A.C. machines were the only ones on the market for a number of years, several wound management companies have now brought out their own machines and these are now known collectively as topical negative pressure therapy (TNPT). Traditional TNPT is often considered a relatively costly procedure. It is often used in patients with large wounds to facilitate dressing management and promote rapid cleaning and granulation. This may also allow them to be discharged to the community when they would otherwise remain inpatients, thereby saving bed days. Capital purchase of the machines is expensive and hospitals often rent or lease them on a short or long term basis. This can lead to difficulties in arranging the finances for discharge to the community. Subsequent dressing changes (recommended every 48 - 72 hrs) also incur high costs and involvement of the trained medical or nursing staff. As we all know; “Need is the mother of invention”. The disposable TNPT machine (V.A.C. ViaTM KCI Medical Ltd) has been introduced to help to solve these problems. It is a single use machine, inclusive of a dressing and canister and available off the shelf. It is very cost effective, easy to use and is used for small to moderate sized wounds. Senior author is using this machine which excellent results and illustrated the use of this machine with pictures in this paper.
Reference Sequence Construction for Relative Compression of Genomes
Shanika Kuruppu,Simon Puglisi,Justin Zobel
Mathematics , 2011,
Abstract: Relative compression, where a set of similar strings are compressed with respect to a reference string, is a very effective method of compressing DNA datasets containing multiple similar sequences. Relative compression is fast to perform and also supports rapid random access to the underlying data. The main difficulty of relative compression is in selecting an appropriate reference sequence. In this paper, we explore using the dictionary of repeats generated by Comrad, Re-pair and Dna-x algorithms as reference sequences for relative compression. We show this technique allows better compression and supports random access just as well. The technique also allows more general repetitive datasets to be compressed using relative compression.
An empirical Bayes derivation of best linear unbiased predictors
Rohana J. Karunamuni
International Journal of Mathematics and Mathematical Sciences , 2002, DOI: 10.1155/s016117120211009x
Abstract: Let (Y1,θ1),…,(Yn,θn) be independent real-valued random vectors with Yi, given θi, is distributed according to a distribution depending only on θi for i=1,…,n. In this paper, best linear unbiased predictors (BLUPs) of the θi's are investigated. We show that BLUPs of θi's do not exist in certain situations. Furthermore, we present a general empirical Bayes technique for deriving BLUPs.
Tacit Knowledge Sharing and SMEs’ Organizational Performance
Rohana Ngah,Kamaruzaman Jusoff
International Journal of Economics and Finance , 2009, DOI: 10.5539/ijef.v1n1p216
Abstract: Tacit knowledge (TK) exists in every corner of SME, in its structure and relationship especially in its people. Even though knowledge management will benefit SME as they are rich of tacit knowledge but lacking in expertise, financial capital and infrastructure, knowledge management (KM) is almost impossible for Small and Medium Enterprise (SME) currently. Since SME have efficient and informal communication network, knowledge sharing is essential especially in an organization with scarce resources. Therefore, in the wake of knowledge-based economy, tacit knowledge sharing is the best tool for SME in enhancing competence and organizational performance which suit its needs and background. Tacit knowledge sharing is still at infancy especially in SME.

Rohana Basil Marasinghe
Sri Lanka Journal of Bio-Medical Informatics , 2010, DOI: doi: 10.4038/sljbmi.v1i3.2056
Abstract: Provision of healthcare at a distance is not a new concept. However, with the advancement of Information and Communication Technologies (ICT), the term ‘Telehealth’ has been cited frequently in the health/medical literature. Similar terms such as ‘Online Health’, ‘eHealth’ and Telemedicine’ are also begining to appear. The purpose of this article is to provide readers with an understanding of telehealth with special reference to Sri Lanka. First, different terms and definitions related to telehealth will be reviewed. Then, the history of telehealth and evolutionary milestones of telecommunication activities will be examined. Next, telecommunication activities in Sri Lanka and its trend will be explored. Later, telehealth effectiveness will be examined briefly. Finally, a brief overview of telehealth activities related to Sri Lanka will be presented before suggesting a way forward.
