Several approaches in the past have been proposed that deal with problem of recognition of numerals/character depending on the type of feature extracted and way of extracting them.

Data on the burden of visceral leishmaniasis (VL) in Indian sub-continent are vital for elimination programme planners for estimating resource requirements, effective implementation and monitoring of elimination programme. In Indian sub-continent, about 200 million population is at risk of VL. Nearly 25,000-40,000 cases and 200-300 deaths are reported every year, but these are grossly underesti...

Seventeen Indian hepatitis E virus (HEV) isolates, representing epidemic and sporadic hepatitis E cases during 1976-1991, were sequenced in the RNA polymerase (RNAP) region. Five isolates were also sequenced in the non-structural hypervariable region of open reading frame 1. Open reading frames 2 and 3 were sequenced only for the prototype isolate. On the basis of the comparison of all the avai...

Sea surface temperatures (SSTs) in the equatorial Indian Ocean have warmed by about 0.6–0.8 K since the 1950s, accompanied by very little warming or even a slight cooling trend over the northern Indian Ocean (NIO). It is reported that this differential trend has resulted in a substantial weakening of the meridional SST gradient from the equatorial region to the South Asian coast during summer, ...
