Potpourri of Research Articles - T V Ananthapadmanabha (Ed.):

Each volume of the series is a collection of research articles written by the author either alone or with some research collaborators that have not been formally published in peer reviewed journals. The articles are written in an informal style as Technical Notes with emphasis on the main idea and results. Thus, no attempt has been made to present an exhaustive review of the previous works or to cite all the relevant references. The purpose is to share the ideas or thoughts with co-researchers in the field with the hope that these thoughts or ideas may trigger interest in the researchers ultimately resulting in publications in peer reviewed Journals or in some technological applications.
