Journal ArticleDOI
The signals and systems concept inventory
TL;DR: The three-year development of the Signals and Systems Concept Inventory is summarized and results obtained from testing with a pool of over 900 students from seven schools are presented.
Journal ArticleDOI

TL;DR: Comparisons of measurements of a commercially available UWB antenna performance in an anechoic chamber and in various indoor multipath environments indicate that while the human body creates a deep null in a light multipath environment, this null is drastically reduced in a dense multipATH environment.
Journal ArticleDOI
Use of one-dimensional iris signatures to rank iris pattern similarities
TL;DR: A one-dimensional approach to iris recognition that uses the Du measure as a matching mechanism, and generates a set of the most probable matches (ranks) instead of only the best match.
Proceedings ArticleDOI
A new approach to iris pattern recognition
TL;DR: An iris identification algorithm is proposed based on adaptive thresholding that could possibly be utilized for partial iris recognition since it relaxes the requirement of using a majority of the iris to produce an iris template to compare with the database.
