    Kathana - fluent speech recognition system based on hidden markov model for Sinhala language
    (Computer Science & Engineering Society c/o Department of Computer Science and Engineering, University of Moratuwa., 2010-09) Jayasena, S; Wimalawame, K; Munasinghe, TR; Cooray, NMP; Yatawattc, HR; Rajapakse, DCP; Gunasekara, C; Wijegunawardana, P; Pavalanathan, U
    This paper discusses speech recognition based on Hidden Markov Model for Sinhala language. There are two main speech technology concepts in this scenario as speech synthesis and speech recognition. Speech synthesis is the artificial production of human speech. Speech recognition is the process of converting an acoustic signal, captured by a microphone or a telephone, to a set of words. This paper is based on KATHANA speech recognition system where the intention is to develop a system which is capable of converting human speech done in Sinhalese to text/ command.

    Lbnest - layout based news extraction and syndication
    (Computer Science & Engineering Society c/o Department of Computer Science and Engineering, University of Moratuwa., 2009-07) Fernando, S; Perera, AS; Wimalawame, K; Buddhika, T; Kahawala, V; Fonseka, P; Karunanayake, T; Nanayakkara, V; Gunasinghe, UP
    Layout Based News Extraction and are Syndication is an attempt to implement a mechanism for extracting information from the news web sites. This research and development is carried out around some of the identified methodologies and finally the results obtained in each of the approach are discussed. Finally a hybrid approach is proposed which has been identified as the most accurate and efficient approach.

    Programmatic implementation of the karmarkar’s algorithm for vacation package synthesis process optimization
    (Computer Science & Engineering Society c/o Department of Computer Science and Engineering, University of Moratuwa., 2009-07) Ganepola, H; Padukka, J; Prasad, R; Samarakoon, L; Wimalawame, K; Nanayakkara, V; Gunasinghe, UP
    Vacation Packages are a basic component of the modern travel industry. Putting together a set of vacation packages, which can generate the highest revenue to the tour operator, is a hectic task which will need a lot of man hours. In this paper, we present a linear programming approach which ensures the maximum revenue to the tour operator, where all the contract constraints are satisfied. From LP model formulation to the solving algorithm and its results will be presented in this paper. Karmarkar’s Projective Scaling algorithm, which is the solving algorithm will be explained in the process, with its implementation approach
