Online Hindi Handwritten Recognition
Online handwritten word is generated as X-Y coordinates of pen like device applied on touch sensitive screen. X-Y coordinates of pen tip are recorded as time dependent signal. Pen-down state occurs when the pen touches the screen and pen-up state occurs when pen is lifted from the screen.

Speech Enhancement Approaches
In the past decade, there has been tremendous improvements in the field of automatic speech recognition (ASR). Despite these, the performance of an ASR system degrades significantly in the presence of noise due to the mismatch be- tween the training and test environments.
