    De Silva, N; Thurairajah, N; Ransinghe, M [Conference-Abstract]
    Assembling of nemal networks refened to as "Ensemble nemal networks·· consist with many small "expei1 networks" that leam small parts of the complex problem. which are established by decomposing it into its sub leYels. ...
  • Forecasting stock price of a company considering macroeconomic effect from news events 
    Waduge, N; Ganegoda, U [Conference-Full-text]
    Investment perspective, Stock Market is the most popular potential investment market around the globe currently, because of this reason the need of an effective stock prediction approach was a target of many researchers. ...
  • Mathematical modeling of hidden layer architecture in artificial neural networks 
    Wagarachchi, NM; Karunananda, AS [Conference-Abstract]
    The performance of a multilayer artificial neural network is very much depends on the architecture of the hidden layers. Therefore, modeling of hidden layer architecture has become a research challenge. At present most ...
  • Predicting unsafe behaviour of construction workers 
    Manjula, NHC; De Silva, N [Conference-Full-text]
    The construction industry is known to be one of the most accident-prone of work sectors around the globe. Although the construction output is less in Sri Lanka, compared to developed countries in general, the magnitude ...
  • Risk analysis in maintainability of high-rise buildings under tropical conditions using ensemble neural network 
    De Silva, N; Ranasinghe, M; De Silva, CR [Article-Full-text]
    Purpose – The aim of this research study is to develop a risk-based framework that can quantify maintainability to forecast future maintainability of a building at early stages as a decision tool to minimize increase of ...
  • Sizing of reinforced concrete structural members based on Sri Lankan design data 
    Konara, MRN [Thesis-Abstract]
    The majority of building structures in Sri Lanka, are of reinforced concrete. Often it is required to estimate structural member sizes at the initial stage of a building construction project for load evaluation, cost ...
  • Spatial electric load forecasting model for Sri Lanka 
    Madawala, MK [Thesis-Full-text]
    With the high level of city expansion observed during the last few decades, distribution utilities currently face new challenges when planning network expansion with profitable operations. Thus distribution utilities should ...
  • Use of ANNs in complex risk analysis applications 
    De Silva, N; Ranasinghe, M; De Silva, CR [Article-Full-text]
    Purpose – Artificial neural network (ANN) has been used for risk analysis in various applications such as engineering, financial and facilities management. However, use of a single network has become less accurate when ...
  • Utilisation of rice husk ash for soil stabilisation 
    Ranathunga, RJKPN; Sampath, KHSM [Conference-Abstract]
    Rice husk ash (RHA) is one attractive additive that can be used for the enhancement of engineering properties of problematic soils as a full/partial replacement of cement/lime. The present study reviews the production ...
