Virtual tool mark generation for efficient striation analysis in forensic science

Description: In 2009, a National Academy of Sciences report called for investigation into the scienti#12;c basis behind tool mark comparisons (National Academy of Sciences, 2009). Answering this call, Chumbley et al. (2010) attempted to prove or disprove the hypothesis that tool marks are unique to a single tool. They developed a statistical algorithm that could, in most cases, discern matching and non-matching tool marks made at di#11;erent angles by sequentially numbered screwdriver tips. Moreover, in the… more

International Legal Framework for Denuclearization and Nuclear Disarmament – Present Situation and Prospects

Description: This thesis is the culminating project for my participation in the OECD NEA International School of Nuclear Law. This paper will begin by providing a historical background to current disarmament and denuclearization treaties. This paper will discuss the current legal framework based on current and historical activities related to denuclearization and nuclear disarmament. Then, it will propose paths forward for the future efforts, and describe the necessary legal considerations. Each treaty or a… more

Measuring the Weak Charge of the Proton and the Hadronic Parity Violation of the N -> {Delta} Transition

Description: Qweak will determine the weak charge of the proton, Q{sup p}{sub W}, via an asymmetry measurement of parity-violating elastic electron-proton scattering at low four momentum transfer to a precision of 4%. Q{sup p}{sub W} has a firm Standard Model prediction and is related to the weak mixing angle, sin{sup 2} {Theta}{sub W}, a well-defined Standard Model parameter. Qweak will probe a subset of new physics to the TeV mass scale and test the Standard Model. The details of how this measurement was … more
