Abstracts -- Fall 2017

September 14, 2017: Dr. Ying Liu: "Securing Birth Certificate Documents with DNA Profiles"
Abstract: The birth certificate is a document used by a person to obtain identification and licensing documents throughout their lifetime. For identity verification, the birth certificate provides limited information to support a person’s claim of identity. Authentication to the birth certificate is strictly a matter of possession. DNA profiling is becoming a commodity analysis that can be done accurately in under two hours with little human intervention. The DNA profile is a superior biometric to add to a birth record because it is stable throughout a person’s life and beyond. Acceptability of universal DNA profiling will depend heavily on privacy and safety concerns. The U.S. FBI CODIS profile is used as a basis to discuss the effectiveness of DNA profiling and to provide a practical basis for a discussion of potential privacy and authenticity controls. It is important to note that adopting DNA profiles to improve document security should be done cautiously.

September 28, 2017: Dr. Satyanand Singh: "A look at the radical side of trigonometry"
Abstract: In this presentation we will illustrate by geometric and algebraic means how one can calculate the exact values of sin(3n), where n takes on integral values in the interval 0 ≤ n ≤ 9. In this journey we will encounter different shapes such as 
and travel along a complex path to derive a multitude of ways to represent sin(1◦). These notions readily extends to other trigonometric functions.
