INTRODUCTION The new case detection rate of leprosy and new cases among children remain high in Sri Lanka indicating ongoing transmission. Identification of the positive contacts and the source of infection would break this chain of transmission. Contact tracing is known to identify early disease and thus prevent disabilities. However, in the recent past little emphasis has been laid on contact...

The T(4)-free thyroxine index was used as the thyroid function test of first choice in a district general hospital for one year. Ninety-two patients were assessed both initially and at follow up by a single physician. The index agreed with clinical assessment in 69 out of 74 patients in whom diagnosis was unequivocal. There was initial doubt about thyroid status in 14 patients; after re-assessm...

Energy saving is one of the most important issues in wireless mobile computing. Among others, one viable approach to achieving energy saving is to use an indexed data organization to broadcast data over wireless channels to mobile units. In this paper, we explore the issue of indexing data with skewed access for sequential broadcasting in wireless mobile computing. We propose methods to build i...

A lot of research and various techniques have been devoted for finding the topological descriptor Wiener index, but most of them deal with only particular cases. There exist three regular plane tessellations, composed of the same kind of regular polygons namely triangular, square, and hexagonal. Using edge congestion-sum problem, we devise a method to compute the Wiener index and demonstrate th...
