Hybrid approach for financial forecasting with support vector machines

Roshan, WDS [Thesis-Full-text]

Financial markets are the biggest business platforms in the world. Therefore, financial forecasting is getting a lot of attention in today’s economic context. Accurate forecast is beneficial to broker firms, governments, ...
Evaluvating the potenital of adopting clean development mecahanism for implementing renewable energy based projects in Sri Lanka

Samarasinghe, JB [Thesis-Abstract]

Sri Lanka has had a hydropower dominated electricity generation for many years with relatively high rainfall mainly in the central hilly region. This factor has led to a greater dependence on hydropower for its power ...
Multi criterion decision making based on techno-economical optimization of stand-alone hybrid energy systems

Perera, ATD [Thesis-Abstract]

Hybrid Energy System (HES)s areincreasingly becoming popular for standalone electrification due to global concerns on GHG emissions and higher depletion of fossil fuel resources. Simultaneously research work on optimal ...
Prediction of flow field of a ceiling fan by flow singularity modeling

Samaraweera, KKMNP [Thesis-Abstract]

Three dimensional flow field of a ceiling fan is modelled numerically by assuming incompressible and inviscid flow. The fan blades modelled by vortex lattice method, in which surfaces are replaced by vortex boxes. The ...
Multi agent based control and protection for an inverter based microgrid

Kulasekera, AL [Thesis-Abstract]

Legacy electrical infrastructure is failing to provide the reliability and the resiliency towards faults expected by the modern energy intensive society. Implementation of smarter microgrids, are proving to be part of the ...
Performance evaluation of an innovative tea dryer using mathematical modeling

Shantha, KYHD [Thesis-Abstract]

This entire research work is focused for the performance evaluation of an Innovative tea dryer using a technique of mathematical modeling. The innovative tea dryer was designed and fabricated targeting the group of farmers ...
Heat gains to building interiors through roofs : a study based on selected configurations in Sri Lanka

Sirimanna, MPG [Thesis-Abstract]

Roofs of residential buildings play a crucial role in the context of building heat gains and thermal comfort, since they are exposed to a significant portion of insolation during the day. Therefore, it is important to ...
Investigation of problematic issues of mould design and manufacture for plastic-based industry in Sri Lanka

Galappaththi, UIK [Thesis-Abstract]

At present the demand for high precision, high quality dies and moulds in Sri Lanka is around Rs. 1500 million. However, local supply is around Rs.300 millions. The gap of supply and demand is also increasing day by day. ...
Development of solar powered pumping for the integration of rainwater harvested in multistory houses

Sendanayake, S [Thesis-Abstract]

Rain water Harvesting (RWH) is an ancient civil practice for more than 4000 years, drawing attention among scientists in recent decades in the light of potable water shortages and water based natural disasters such as ...
Multi-dimensional numerical simulation of scavenge flow in a small two-stroke engine

Wijeyakulasuriya, SD [Thesis-Abstract]

Computational study of scavenging flow in a typical small vehicle engine is accomplished using multi-dimensional moving-mesh unsteady and quasi-steady models. A representative two-stroke 5 port engine was selected and ...
