    Mohamed Rilji, MR; Bandara, HMND; Ranathunga, S [Conference-Abstract]
    We describe a solution for real-time matching of microblogging messages related to product selling or buying. C2C buy/sell interest matching in real time is nontrivial due to the complexities of interpreting social media ...
  • A profit maximization approach for organic short food supply chains 
    Jayalath, MM; Perera, HN; Thibbotuwawa, A; Hettiarachchi, BD [Conference-Full-text]
    Demand for organic food is rapidly increasing. This is despite several constraints in the process of producing organic foods. Producers should aim to maximize their profit by catering to the rising demand of this niche ...
  • Programmable fault path indicator for power distribution networks 
    De Silva, N; Kumarawadu, S; Selvarasa, A; Ratnayaka, SRMCD; Ranawaka, DMD; Kankanamge, TN [Conference-Extended-Abstract]
    The increase in electricity demand and expansion of transmission and distribution system is leading to a more complex electrical network. As a result of complex networks, fault identification takes a longer time posing a ...
  • A programming framework for robot swarms 
    Dassanayaka, M; Bandara, T; Adikari, N; Nawinne, I; Ragel, R [Conference-Full-text]
    Swarm robotics is a well-evolved research area over the past couple of decades. In this paper, we introduce a framework for programming swarm robots in a novel approach based on behaviour categorization, pheromone ...
  • Project manager to combat corruption in procurement: some issues with special reference to Sri Lanka 
    Kodikara, GW [Conference-Full-text]
  • Property analysis of cellulose fibers extracted from traditional rice straw varieties 
    Ratnakumar, A; Samarasekara, AMPB; Amarasinghe, DAS; Karunanayake, L [Conference-Full-text]
