| The North Korean nuclear crisis needs to be understood comprehensively, taking into account both international relations and the domestic political dynamics of the countries involved. This thesis analyzes North Korean and U.S. policies during two nuclear crises (1993-1994 and 2002-present) and proposes an option for reaching a nuclear-free Korean Peninsula. The results show that North Korea has pursued nuclear weapons with a unique historical, cultural, and political strategy. It has ... |

| The Frozen Rock Experiment (FRE) was conducted in central Alaska in August 2006 to provide empirical data on seismically-estimated yield from explosions in frozen rock. Laboratory studies have demonstrated that frozen rock is significantly stronger than unfrozen rock, and it has been hypothesized that this increased strength, due to ice in the pores and cracks, can alter seismic yield. Central Alaska has abrupt lateral boundaries in discontinuous permafrost, and we ... |

| Science Applications International Corporation (SAIC) is testing a semi-empirical signal processing approach to estimate the yield of explosions. Under Air Force Research Laboratory contract FA8718-05-C-0019, SAIC developed a technique to combine the `truth' of empirical observation with the flexibility of synthetics to generate empirical filters that can be applied to the synthetic seismogram. Specifically, our approach is to design filters that transform the synthetic waveforms to match observed referenced waveforms. ... |

| In spite of extensive prior research on the generation of seismic waves by underground nuclear explosions, it is still not possible to provide a complete explanation for the observed wavefields, particularly at regional distances. Spherically symmetric explosion models embedded in layered elastic media effectively model the P phases generated by explosions and the major characteristics of some reflected and transmitted phases. Nonlinear axisymmetric finite difference calculations of explosions, including gravity ... |

| To improve seismic calibration for nuclear explosion monitoring, we use 3D sensitivity kernels of finite-frequency body and surface waves to develop models of the crustal and mantle structures beneath eastern Eurasia. We have collected and processed available broadband data from both permanent stations and temporary networks in eastern Eurasia. We obtained a regional P-wave velocity model for the mantle structures down to 1,500 km beneath the eastern Eurasia. We also ... |

It also is controversial because the United States is agreeing to recognize India as a nuclear power even though India is not a signatory to the 1968 Nuclear Nonproliferation Treaty (NPT). The primary purpose of this thesis is to assess China's reactions to ... |
