  • Controllability of a system of coupled harmonic oscillators 
    De Silva, R. N. S.; Hansameenu, W. P. T. (Research Symposium on Pure and Applied Sciences, 2018 Faculty of Science, University of Kelaniya, Sri Lanka, 2018)
    In general, it is worthwhile to understand and control the dynamics of an existing system whose output behaves somewhat closer to the desired output rather than developing a new system which tracks the desired output, since ...
  • Design of heat sink and simulation of electronic cooling of power transistor circuit 
    Gunasinghe, L. M.; Samaranayake, W. J. M.; Hansameenu, W. P. T. (Faculty of Science, University of Kelaniya Sri Lanka, 2022)
    Heat sinks are utilized in industrial equipment to disperse surplus heat from heat-generating components to the surrounding environment. In recent years, efforts have been made to develop mechanical or electronic devices ...
  • The Holt-Winters’ method for forecasting water discharge in Attanagalu Oya 
    Anuruddhika, M. L. P.; Premarathna, L. P. N. D; Perera, K. K. K. R.; Hansameenu, W. P. T.; Weerasinghe, V. P. A. (Faculty of Science, University of Kelaniya, Sri Lanka., 2021)
    Forecasting river water discharge is significant in developing flood and agriculture management plans. Annual flood events damage properties, agricultural field, and infrastructures, etc. can be observed in Attanagalu Oya ...
  • Numerical evaluation of wave energy absorption and performance of a selection of wave energy converters in southern sea conditions of Sri Lanka 
    Vishvanath, N. A. V.; Weerasinghe, M. H. L.; Hansameenu, W. P. T. (Faculty of Science, University of Kelaniya Sri Lanka, 2022)
    Ocean wave energy is undoubtedly the next crucial step in Sri Lanka’s energy sector. The abundance of this source of green energy, mainly in the Southern seas of Sri Lanka, has been identified and estimated in a handful ...
  • Study of the improvement of Ozone production: A simulation 
    Amarakoon, A. M. M. N. B.; Hansameenu, W. P. T.; Samaranayake, W. J. M. (Faculty of Science, University of Kelaniya Sri Lanka, 2022)
    Ozone is an unstable, colourless gas that has a pungent odour which occurs naturally in small amounts in the stratosphere. Ozone is one of the strongest oxidants. Major applications of ozone are disinfection, deodorization, ...
  • Tracking problem of 1D damped translational mechanical system for harmonic signals 
    Leelarathne, H. M. A. K.; Hansameenu, W. P. T. (4th International Research Symposium on Pure and Applied Sciences, Faculty of Science, University of Kelaniya, Sri Lanka, 2019)
    The translational mechanical systems play a major role in engineering systems such as automobile shock absorbing system, stock bridge damper, motion sensor etc. However, the damping influence of the translational mechanical ...
  • Viscous Dissipation and thermal radiation of Williamson fluid flow over an exponentially stretching sheet 
    Karunathilake, N. G. A.; Hansameenu, W. P. T.; Wijesiri, G. S. (Karunathilake N. G. A.; Hansameenu W. P. T.; Wijesiri G. S. (2023), Viscous Dissipation and thermal radiation of Williamson fluid flow over an exponentially stretching sheet, Proceedings of the International Conference on Applied and Pure Sciences (ICAPS 2023-Kelaniya) Volume 3, Faculty of Science, University of Kelaniya Sri Lanka. Page 78., 2023)
    This study investigates the viscous dissipation and thermal radiation of Williamson fluid flow over an exponentially stretching sheet. The analysis has been started with the governing equations of the fluid flow derived ...
