    Accurate interpretation of the Load-settlement data obtained by static or dynamic load testing of piles is very important to understand the load carrying mechanism of the pile. Even though dynamic load test results provide ...
  • Ultra sound technique in natural dye application to textiles 
    Samudrika, UG; De Silva, NGH; De Alwis, AAP; Vankar, PS [Conference-Extended-Abstract]
    The conventional method of textile dyeing has been to boil the fabric or yarn in dye bath, till the desired color is obtained. Enormous amount of heat is consumed in terms of heating the dye bath. Some dyes, which are heat ...
  • Tsunami hazards: public awareness and response 
    Samarawickrama, SP; Ratnasooriya, AHR; Hettiarachchi, SSL; Lawrance, MKD; Kumara, GGA [Conference-Extended-Abstract]
    The objective of this research study was to assess the degree of public awareness on tsunamis. The results of the study are useful in planning awareness programs, the preparation of the Hazard Maps and in the implementation ...
  • Transient response and stability of anaerobic reactors following interm tttant feeding 
    Rathnasiri, PG; Hayun; Bakke, R [Conference-Extended-Abstract]
    Anaerobic treatment offers a number of attractive advantages in the treatment of highstrength organic waste water, but difficulties in maintaining process stability is a disadvantage. The process is sensitive to changes ...
  • The flow behavior of mineral particles through glass funnels 
    Rohitha, LPS; Dissanayaka, DMDOK; Fernando, WLW [Conference-Extended-Abstract]
    In industry the flow of mineral particles in silos playa very important role in the recovery of these particles into containers for bagging and transport. The silo design parameters and particulate properties are restricting ...
  • The effect of scaling on frictional losses in pipes 
    Wijesekera, NTS; Ratnasooriya, AHR [Conference-Extended-Abstract]
    The ability to predict the hydraulic performance of a pipe network during its working life plays an important role in the planning and design of water supply schemes. The nominal diameter and the friction factor of pipes ...
  • The effect of infill on shear behaviour of idealised joints under constant normal stiffness conditions (CNS) 
    Welideniya, HS [Conference-Extended-Abstract]
    The shear behaviour rock joints infilled with graphite, bentonite and clayey sand under eNS conditions were studied through a comprehensive laboratory testing programme to assess its influence on rock mass stability. A ...
  • Runoff coefficients of three wet zone watersheds of Sri Lanka 
    Perera, KRJ; Wijesekera, NTS [Conference-Extended-Abstract]
    Computing runoff is very important in water resources development. Estimating runoff from rainfall records in the absence of stream gauge records is extremely important. It is more so in Sri Lanka where most of our watersheds ...
  • Rice husk as a low cost adsorbent for removal of malachite green and nylosan blue from aqueous solutions 
    Jayatunga, GK; Amarasinghe, BMWPK [Conference-Extended-Abstract]
    Colored dye waste water arises as results of the production of dye and also as a consequence of its use in textile industry. Many types of dyes are used in the textile industries such as direct, reactive, acid and basic ...
  • Resistance to tsunami inundation vegetation: an experimental study by coastal 
    Ratnasooriya, AHR; Samarawickrama, SP; Hettiarachchi, SSSL; Bandara, RPSS [Conference-Extended-Abstract]
    More than two thirds of the coastline of Sri Lanka was subjected to inundation by the Indian ocean tsunami on 26 December 2004. The inundation distance and the associated damage caused by the tsunami varied widely with the ...
  • Predicting the behaviour of a distributed system 
    Femando, S; Gunawardhane, LADSS; Illangasinghe, IKMRM; Jayasooriya, AS; Jayathilake, HPID [Conference-Extended-Abstract]
    A distributed system is a set of processes that are running in a set of networked machines to perform a set of interrelated tasks. For the correct functionality of the distributed system each and every process should work ...
  • Potential of biomethane as a transport fuel and development of pilot scale co•digestion plant for treating source separated canteen waste 
    Rathnasiri, PG; Kularatna, MADIC; De Alwis, AAP [Conference-Extended-Abstract]
    In recent years the interest in bio-fuels has been increasing, motivated in the one side by the need for reducing green house gas emissions and on the other side by the desire to improve energy security by reducing our ...
  • Online sinhala handwritten character recognition for desktops 
    Dias, G; Patikirikorala, TNP; Arambewela, CI; Darshani, RPM; Alahendra, ND [Conference-Extended-Abstract]
    Online Sinhala handwritten character recognition is a fairly under-developed, albeit well researched area in the local natural language initiative. Recent attention towards this area produced an application named PanhinDA, ...
  • Numerical modelling of tsunamis - case study from Galle 
    Samarawickrama, SP; Hettiarachchi, SSL; Ratnasooriya, AHR [Conference-Extended-Abstract]
