    This research investigates the reasons for inverter building project failures. Most of the projects which are based on inverter circuit design fail due to switching spikes and/or malfunction of IGBT/MOSETs. This paper ...
  • Experimental Investigation of an Efficient Retrofitting Technique for Corroded Concrete Structures 
    Ahamed, M.Z.S.; Rathnayake, R.M.M.C.; Ifham, M.R.M.; Sanjeewa, H.V.A.N.; Appuhamy, J.M.R.S. (Faculty of Engineering, University o f Ruhuna,Hapugala, Galle, Sri Lanka., 2017-01-05)
    The repair and rehabilitation of reinforced concrete structures in coastal areas is a major challenge to civil engineers. These structures often require repairs due to concrete deterioration caused by reinforcement ...
  • Reduction of Dynamic Strength Capacities of Reinforced Concrete Structures under Different Corrosion Conditions 
    Ifham, M.R.M.; Ahamed, M.Z.S.; Rathnayake, R.M.M.C.; Sanjeewa, H.V.A.N.; Appuhamy, J.M.R.S. (Faculty of Engineering, University o f Ruhuna,Hapugala, Galle, Sri Lanka., 2017-01-05)
    Steel reinforcement corrosion is one of the major deterioration mechanisms of Reinforced Concrete (RC) structures. Once the corrosion signs appear on the concrete surface, it'll intensify further corrosion and as a result, ...
  • Prediction of Residual Strength Capacities of Reinforced Concrete Structures under Different Corrosion Conditions 
    Rathnayake, R.M.M.C.; Ifham, M.R.M.; Ahamed, M.Z.S.; Sanjeewa, H.V.A.N.; Appuhamy, J.M.R.S. (Faculty of Engineering, University o f Ruhuna,Hapugala, Galle, Sri Lanka., 2017-01-05)
    Corrosion of reinforcement embedded in concrete is a significant problem in the world. Chloride induced corrosion is a major problem for reinforced concrete (RC) structures. Due to corrosion, cross-sectional steel area ...
  • Investigation of Safety Allocation for Construction Projects Using Accident Cost Analysis 
    Premawardhana, E.M.T.P.; Malkanthi, S.N. (Faculty of Engineering, University o f Ruhuna,Hapugala, Galle, Sri Lanka., 2017-01-05)
    Construction sector in Sri Lanka has tremendously grown in the recent past. Since the construction industry is based on manpower, health and safety of workers should be in higher position. However, healdr and safety has ...
  • Field-Scale Anaerobic Filter System with Low-Cost Packing Media for the Treatment of Landfill- Leachate 
    Fernando, D.M.T.; Chamenuka, K.G.D.; Dayanthi, W.K.C.N. (Faculty of Engineering, University o f Ruhuna,Hapugala, Galle, Sri Lanka., 2017-01-05)
    Anaerobic filter is a major concern in the treatment of landfill-leachate and one major drawback is the usage of expensive packing media. Hence the investigations on low-cost and locally available packing media would be ...
  • Low-Cost Anaerobic Treatment Method for Landfill-Leachate 
    Herath, H.M.L.V.K.; Tharanga, K.H.S.S.; Nanayakkara, B.S.R.; Dayanthi, W.K.C.N. (Faculty of Engineering, University o f Ruhuna,Hapugala, Galle, Sri Lanka., 2017-01-05)
    Anaerobic treatment methods are usually suitable for landfill-leachate. However, most of the anaerobic methods are quite expensive due to the high cost of artificial filtration media. Hence the aim of this study was to ...
  • Validation of a Phytoplankton Model Over a Coastal Fishing Reef Using Satallite Data 
    Yapa, C.J.D.; Vithana, H.P.V. (Faculty of Engineering, University o f Ruhuna,Hapugala, Galle, Sri Lanka., 2017-01-05)
    Due to current patterns and heavy nutrient loads from rivers, phytoplankton production rates can cause algal blooms. Since earth observation delivers a synoptic view of the ocean, together spatially and temporally, ...
