    Fernando, P.C.B.; Wijeratne, Agra T.; Abeysiriwardena, M. (1995)
    Some physical characteristics of spheres contained in the soot of a high temperature carbon arc, are discussed.
  • A New Method of Generating Pythagorean Triples 
    Wijeratne, Agra T.; Anurasiri, D.I. (2002)
    Pythagorean numbers have captured the imagination of the man for their beauty from the times of Pythagoras (i.e., from 582 BC) or possibly before. The most familiar Pythagorean triples are (3,4,5) and (5,12,13). ...
  • Spheres Produces in a Graphite Film Bombarded by Electrons 
    Fernando, P.C.B.; Wijeratne, Agra T. (1999)
    An approximate relationship is derived between bombarding electron characteristics and the size of carbon spheres produced. using a mechanism proposed by the authors.
  • Vibrational Modes of a Rabana (Drum) 
    Wijeratne, Agra T.; Peiris, M.G.C.; Dharmapriya, G.G. (1998)
    The vibrational modes of a "Virindu" Rabana membrane (of diameter 13 inches), which was driven by a loudspeaker, were studied by using a microphone.The vibrational modes were observed at frequencies below 500Hz. The nodal ...
