The ultimate objective of this work is todevelop an environment that can be used for multiple research initiatives related to usability andsecurity. Introduction Biometrics, the science of reading measurable, biological characteristics of an individualin order to identify them to a computer or other electronic system1, has become a very popularfield of research. In recent years advancements in technology have made researching biometricsless expensive. Facial recognition, in particular, has become a field in which establishing aresearch environment has become much simpler. Current

Thework presented was done with a freshman mathematics major at Texas A&M–Corpus Christi.The student joined a continuing project of the Division of Nearshore Research which usesvarious models to predict water levels along the Texas coast. The most successful models useneural networks written in Matlab and are trained with a backpropagation algorithm. The trainingset consists of one year’s worth of hourly water level and wind data. Initially the weights andbiases of all neurons are assigned at random or with the Nguyen–Widrow algorithm. With theseweights and biases, the forecast is computed and then compared to the actual water levels. Ineach training epoch, the weights and biases are updated following

They were encouragedto contact and gain information from their counterparts at other institutions where suchcodes were in place. There were several Town Hall meetings and the entire MechanicalEngineering student body was invited to participate. This was part of a series ofMechanical Engineering Leadership Programs sponsored by Ford Motor Company, and itwas felt that these initiatives would serve to build a community of scholars, as well as asense of professionalism.

Second, the number of semesters a studentis consecutively enrolled tends to be negatively correlated with GPA. Initially, thisseems incongruent with the research showing that full-time students are more likely topersist than part-time students3,11,7,10,16, and that persistence is related toGPA2,4,11,12,14,16,18,20. However, most of the students in our study were enrolled full-timeat a tier-1 research university, and full-time students who take on too many hours maybe at a disadvantage because they can not devote as much time to each class as canfull-time students who take fewer hours

The pull-out force per unit length of interference is taken to be a measure of theeffectiveness of the fastener. The variation in the push-in and pull-out force with the insertiondepth shows that the push-in force increases with insertion depth and a sharp increase is seenas the spring begins to deform. The pull-out force is maximal while initiating separation andsignificantly affected by the bone/fastener friction.

Abstract This paper highlights recent developments in the creation and implementation ofeducational modules for the instruction of probability modeling and simulation in secondaryeducation. Each module consists of a collaboratively produced self-contained DVD thatdescribes real-world applications of probability concepts. When implemented in a problemsolving group setting, the modules create a knowledge-based environment for student learning,as is described in the How People Learn research compilation of the National Research Council.The concepts that are learned through the modules coincide with those set forth by the NationalCouncil of Teachers of Mathematics for 9-12 year secondary education students, which include1. the use of simulation
