This is a collection of research materials, discussing mathematical solutions to scientific problems like data mining, computer networks etc. Most of the real-time problems are inverse in nature and among them many are ill-posed. Such problems are a matter of concern among the researchers and scientists.

Many such problems are solved numerically to yield an approximate solution. Some articles in this book discuss these problems and its applications in the area of image and signal processing and give an insightful introduction to the possible approaches to handle them.
