ERU - 2002: Recent submissions

  • Design of a high performance impeller for solid liquid mixing in low viscosity systems 
    Perera, SAS; Hatharasinghe, RC [Conference-Extended-Abstract]
    Mixing impellers are used to dissolve solutes in solvents, disperse solids in liquids and emulsify immiscible liquids. A system that needs mixing can be classified as a low viscosity system, a medium viscosity system or a ...
  • Critical investigation of tongue and groove joint in wooden furniture design and manufacture in Sri Lanka 
    Fernando, MARV [Conference-Extended-Abstract]
    Furniture manufacture during early days was a highly skilled craft where appearance and functions were innovatively designed, but the joints were done in the traditional manner. Though high quality timber was invariably ...
  • Computational modelling of cook-stoves 
    Weerasinghe, R; Bandara, P [Conference-Extended-Abstract]
    Combustion inside a cooking stove is complicated to understand and describe. The process is highly dependant on the inlet conditions, fuel used and the geometry of the stove. It is very difficult to predict the distributions ...
  • Business process re-engineering with IT as a tool 
    Madanayake, OC; Jayawardane, AKW; Wickramarachchi, N [Conference-Extended-Abstract]
    This paper explains the application of Business Process Re-engineering (BPR) combined with IT as a tool to re-engineer the process of issuing transcripts to the graduates of the University of Moratuwa. The deep-set ...
  • Biogas reactors as a resource recovery system in coffee pulp processing 
    Chanakya, HN; De Alwis, AAP [Conference-Extended-Abstract]
    Coffee is an important global product. In fact it ranks only second to oil in traded price volatile commodities of the world - a relatively unknown fact! In most countries where coffee is produced it is for external trade ...
  • BIOCOM-MSW: A composting system for Sri Lankan solid waste management 
    Manipura, A; Jayawardhana, LC; De Alwis, AAP; Pilapitiya, S; Ranasinghe, M; Pathinathar, S; Abeygunawardhana, I [Conference-Extended-Abstract]
    Municipal solid waste has become a major problem in every country in terms of public health and environmental damage. As a developing country, Sri Lanka too faces the same challenge not only through public health and ...
  • Assessment of slope stabilization techniques through a probabilistic approach 
    Kulathilaka, SAS; Mettananda, DCA [Conference-Extended-Abstract]
    Stabilization of slopes that are unstable, or that do not possess a sufficient safety margin, is a major challenge faced by geotechnical engineers. Different techniques are adopted for the stabilization purpose. In central ...
  • Application of GIS in 3G modelling 
    Wijesekara, GN; Thilakasiri, HS; Wickramasinghe, AM; Wickramanayaka, AN [Conference-Extended-Abstract]
    The research primarily was based on application of principles of GIS (Geographical Information System) technology in the field of Geotechnical Engineering. With the objectives being laid towards a model to be applied in ...
  • An information technology (it) approach in developing a solution to a local environmental problem 
    Jayawardhana, LC; Manipura, A; De Alwis, A; Ranasinghe, M; Pilapitiya, S; Abeygunawardena, I [Conference-Extended-Abstract]
    Solid waste (mis)management is one of the most serious local environmental problems in Sri Lanka (Figure 1). It has become a big threat to public health, the beautiful environment and a burden to the national economy.
  • An architecture for advanced proxying based on user requests 
    Fernando, MSD; Dias, G [Conference-Extended-Abstract]
    Much research has been done on issues related to congestion over a data communication link connecting one or more networks to the Internet or a similar network. The main driving force behind such research has been to avoid ...
  • A novel low-cost process for chemical treatment of timber and investlgation of its comparative performance 
    Fernando, MARV [Conference-Extended-Abstract]
    Use of "Rubber" (Hevea basiliensis) timber in furniture manufacture is very common today. Though it has very good strength and nail holding properties, comparable with best quality timber such as "Teak" (Techtona randis), ...
  • A layered beam model to analyse composite truss girders 
    Weerasinghe, MD [Conference-Extended-Abstract]
    In non-steel manufacturing countries like Sri Lanka, where the cost of heavy rolled steel sections are very high, composite floor trusses tend to provide an economical solution in achieving moderate spans in the range of ...
