Scientific Papers
On this page are reprints of two general categories of papers written by Dr Timothy A. Hovanec.
- This includes peer-reviewed research papers written or co-authored by Dr. Timothy A. Hovanec. Peer-reviewed means that before the paper was published in a scientific journal it was first anonymously reviewed by other researchers not connected with the research. These reviewers judged the paper for content and scientific worthiness. Only papers determined to meet sufficient scientific criteria are accepted for publication. This is part of the self-policing of scientists.
- Research papers dealing with a specific topic or subject of research. These papers would have been published in the proceedings of a special conference or workshop, a manual or other type of technical report.
The abstract of each paper is presented to give you a quick review of the paper. All the articles are copyrighted and may not be reprinted or copied in any fashion without the written consent of the copyright holder.
