I would like to thank Harry Swinney for providing invaluable guidance throughout this project. He has made this project the high point of my undergraduate education, and it has been an honor to work with such an accomplished physicist. I thank Matthew Thrasher for helping me in the lab on a daily basis. He has taught me the ins and outs of the entire experimental process showing great insight a...
Results on charmed meson production and decay are presented from the Mark III at SPEAR. FE’ sssociated production is observed allowing a direct measurement of the F’mass. A search for the decay D+ + r+u,, in the recoil of hadronically tagged D* decays provides a stringent limit on the pseudoscalar decay constant jo . New results on DoDo mixing from semileptonic Do decays and evidence for a nonr...
We determine the masses andmagnitude difference of the components of the Hyades spectroscopic binary 2 Tauri. We find that both components appear to be less massive and/or brighter than predicted from some recent evolutionary models. The rapid rotation and unknown rotational inclination of both components introduce uncertainty in their luminosities and colors, but not enough to reconcile both o...

Functional metrics (especially IFPUG Function Point and Mark II Function Point) are gaining dominance over "technological" type metrics (Lines of Code). Although this takes place quite rapidly from the "cultural" standpoint, on a practical level the process is much slower due to the large quantity of code measurements already present in any company, and given the scepticism with which functiona...
In this paper, we propose a secure anti-counterfeiting solution based on the extraction of a unique identifier out of the random profile of laser marks that are engraved on the surface or in the bulk of physical objects. Given today’s technology, the 3D profile of a laser mark can be considered uncloneable. Indeed, reproducing a mark would be so expensive that it thwarts any attempt to build a ...
A tom interferometers have been used to make highprecision measurements in a diverse array of fields. Their more familiar optical counterparts, light interferometers, use matter elements such as mirrors and beam splitters to manipulate light waves. Atom interferometers invert these roles: laser pulses manipulate matter waves of atoms. These pulses split a matter wave into two, redirect the two ...
Focusing on the relationship between product development and economic performance measured by firm growth this paper presents empirical evidence of a positive correlation. Using two comparable questionnaire surveys from mid 1990’s and late 1990’s, accounting statistics and labor market data a logistic regression model is applied on both time periods explaining product development. Besides the p...
