    Nalim, RM; Wijeyakulasuriya, SD [Conference-Extended-Abstract]
    Vehicles are a dominant source of urban air pollution in South Asia, due to a high population of small dirty engines. According to ADB, Asia has the world's highest concentration of two and three wheelers and in many Asian ...
  • A mutipurpose optimized directshow filter for videomixing applications 
    Udawatte, L; De Silva, CR; Chathuranga, SAK; Danansuriya, LNP; Ganegedara, KMHS; Gunasinghe, UP [Conference-Extended-Abstract]
    A video mixer [1] is used to select one or many video streams from different video sources and mix them together to form a single video output. The currently available video mixers use specific hardware devices of very ...
  • A new mathematical model to predict the iodine value of fatty oils 
    Prashantha, MAB; Premachandra, BAJK; Amarasinghe, ADUS [Conference-Extended-Abstract]
    Iodine value is defined as the number of centigrams of iodine per gram of oil sample. Drying property of fatty oils mainly depends on the type of unsaturated fatty acids and relative amounts of each type of fatty acid in ...
  • Numerical modelling of tsunamis - case study from Galle 
    Samarawickrama, SP; Hettiarachchi, SSL; Ratnasooriya, AHR [Conference-Extended-Abstract]
    In the context of Tsunamis the location of Galle is extremely vulnerable. It lies besides a wide bay and a natural headland on which is located the historic Galle Fort with very reflective vertical non-porous walls on all ...
