  • Vigneswaran, R.; Thilaganathan, S. (World Academy of Science, Engineering and Technology, 2016-05-12)
    Variable time-stepping algorithms for solving dynamical systems performed poorly for long time computations which pass close to a fixed point. To overcome this difficulty, several authors considered phase space error ...
  • Kayanan, M.; Wijekoon, P. (International Statistical Institute, 21-08-19)
    The Ordinary Least Square Estimator (OLSE) has been widely used to estimate unknown parameters in the linear regression model. Since OLSE produces high variance on the estimates when multicollinearity exists among the ...

    Wavelength division multiplexing (WDM) divides the huge bandwidth available on a fiber into several non-overlapping wavelength channels and enables data transmission over these channels simultaneously. Failure of the optical ...
  • Gayani, C.; Kokul, T.; Amalka, P. (Springer, 17-12-19)
    Convolutional Neural Networks (CNNs) showed state-of-the-art accuracyin image classification on large-scale image datasets. However, CNNs showconsiderable poor performance in classifying tiny data since their large number ...
  • Loganathan, P.; Vijitharan, S. (Postgraduate of Institute of Science, University of Peradeniya, 06-08-16)
    Consumer awareness is the best way to reduce pesticide related health effects. Many vegetables in the market are contaminated with agrochemicals. Therefore, the present study was designed to investigate the importance of ...
  • Kokul, T.; Fookes, C.; Sridharan, S.; Ramanan, A.; Pinidiyaarachchi, U.A.J. (IEEE, IEEE International Conference on Image Processing (ICIP)., 07-10-18)
    Visual tracking frameworks employing ConvolutionalNeural Networks (CNNs) have shown state-of-the-art performancedue to their hierarchical feature representation. Whileclassification and update based deep neural net tracking ...
  • Vijitharan, S.; Nanthakumaran, A.; Gunatilake, J. (Postgraduate Institute of Science, University of Peradeniya, 10-09-19)
    In Sri Lanka, Aedesaegypti and Aedesalbopictus are reported to be the vectors transmitting dengue fever to human. Socio-economic conditions of the community contribute to mosquito breeding either directly or indirectly. ...
  • Poh, J.S.; Li, Y.; Nagulan, R.; Fortier, M.V.; Chong, Y.S.; Kwek, K.; Saw, S.M.; Gluckman, P.D.; Meaney, M.J.; Qiu, A. (ElSEVIER/NeuroImage, 01-08-15)
    The thalamus is a deep gray matter structure and consists of axonal fibers projecting to the entire cortex, which provide the anatomical support for its sensorimotor and higher-level cognitive functions. There is limited ...
  • Lojenaa, N.; Nawarathna, Ruwan D.; Suthaharan, S. (IRCICT 2018, Edhat International Ltd, 23-11-18)
    The fundamental activity of a bank is money related transactions. To perform such transactions, the banking service providers expect a valid and accurate signature from the customer to ensure correct identification and ...
  • Suthaharan, S; Ratnam, K; Ragel, R.G (IEEE 7th International Conference on Information and Automation for Sustainability (ICIAfS'14), 2014)
    In this paper, we address the problem of providing survivability in elastic optical networks (EONs). EONs use fine granular frequency slots or flexible grids, when compared to the conventional fixed grid networks and ...
  • Amrithaa, P.; Shorubiga, P.; Thanoojan, T.; Kartheeswaran, T. (IEEE, 03-12-20)
    Electricity is one of the inevitable sources of energy in our day to day life. Almost every single device we use from the moment we wake up until going to bed is electrically powered. Meanwhile, there is always a problem ...
  • Gopinath, S.; Nagulan, R. (IEEE, 2020-12-10)
    The deployment of IoT devices in different domains enables technical innovations and value-added services to users but also creates multiple requirements in terms of effective communication and security. IoT devices are ...

    The water hyacinth (Eichhornia crassipes) is a free-floats aquatic plant that has invaded the waterways and reservoirs in the Dry Zone of Sri Lanka. The study focused on preparing a compost using water hyacinth using the ...
  • Suthaharan, S; Sharfana, F A; Thiruvanantharajah, S (IEEE International Conference on Industrial and Information Systems (ICIIS), 2017)
    The advantage of a huge amount of data transmission in form of multimedia broadband services can be benefited using a technique called wavelength division multiplexing (WDM) technology. In WDM, the huge amount of bandwidth ...
  • Vijitharan, S (Vavuniya Campus of the University of Jaffna, 2017)
    Home gardens are conventional agro-forestry systems and characterized by the complexity of their structure and multiple functions. The objective of the study was to investigate the socioeconomic features of the study ...
  • Chowuraya, T.; Kirushanth, S.; Kabaso, B. (Academic Conference International (ACI), 2018-11-12)
    Information is an important part of creating knowledge. We live at a time when so much information is created. Unfortunately, much of the information is redundant. There is huge amount of online information in the form of ...
  • Vijitharan, S (International Institute of Knowledge Management, 17-08-18)
    Home composting is a simple, cost effective and environmentally friendly method to manage the household biodegradable waste. The objectives of the study were to investigate the domestic waste management at household level, ...
