 | A method for the evaluation of military hybrid electric vehicle thermal management systems has been developed. The approach allows for the generation of a set of evaluation metrics for determination of the effectiveness of existing systems and the means to assess alternative concepts and advanced approaches. Further, through the use of a set of deterministic performance metrics the methodology allows for evaluation of performance margins for adverse boundary conditions and ... |

| The Fourth Amendment requires that a search or seizure conducted by a governmental agent be reasonable and supported by probable cause. The Supreme Court has interpreted the Fourth Amendment to include a presumptive warrant requirement on all searches and seizures conducted by the government. Any violation of these requirements could result in the suppression of any information derived therefrom. The Supreme Court, however, has also recognized situations that render obtaining ... |

|
| My thesis covers two general circulation problems that involve the stability of large scale oceanic flows and the importance of non-local effects. The first problem examines the stability of meridional boundary currents, which are found on both sides of most ocean basins because of the presence of continents. A linear stability analysis of a meridional boundary current on the beta-plane is performed using a quasi-geostrophic model in order to determine ... |

| The problems in Afghanistan are not simple and there is no single solution. Indeed, the problems in Afghanistan are not limited to Afghanistan. Instead, the problems extend to all of Afghanistan' immediate neighbors as well as, among others, the United States, NATO, Russia, Iran, and India. However, perhaps nowhere is the problem more pronounced than in Pakistan. Pakistan' relationships with Afghanistan and the rest of the world are heavily influenced ... |

| The objective of our original proposal was to use the Minimum Current Corona (MCC) model to determine where strong currents are likely to develop above an active region, and compare the locations with observed flare signatures. If there is a good correspondence, we can also estimate the energy available for the flare from the current sheet in question. In the MCC model, the magnetic field in the corona is represented ... |

| The violence from Mexico's ongoing fight against narcotraffickers has reached astounding proportions and poses a national security threat to the United States. There is currently a lack of a unified coarse of action for United States Northern Command (NORTHCOM) with respect to Mexico. United States Southern Command's (SOUTHCOM) experience during Plan Colombia can provide insight into how NORTHCOM might proceed through an integrated approach to counterinsurgency (COIN)training, border security and ... |

| The nation's homeland security strategy calls on federal, state, and local governments, businesses, communities, and individuals across the country to work together to achieve a shared vision of a secure way of life. Yet for over seven years, through attacks, threats, and disasters, the core ingredient in efforts to achieve that goal remains elusive. The American public has been left out and is largely missing in action. This elusiveness persists ... |

| Analytical solutions are derived for a one-dimensional model of the bulk temperature response of open-channel flow with unsteady and nonuniform heating at the upstream end, the water surface, and the riverbed. The solutions are explicit formulas comprised of transient terms, which play dominant roles in the upstream region, and equilibrium terms, which determine the temperature far downstream. The applicability of the solutions to practical problems is illustrated for two cases: ... |

Mie theory is used to solve the acoustic and electromagnetic scattering problems for spheres with lossless boundary conditions and an incident plane wave. It is shown that, for certain lossless sheet impedance boundary conditions there exist second ... |

| The GDEM (Generalized Digital Environment Model) has served as the U.S. Navy's global gridded ocean temperature and salinity climatology since its development began in 1975. This memorandum introduces a new version of this climatology, named GDEM-V 3.0, and discusses the techniques used in its construction. Several comparisons are shown between version 3.0 and the previous version (2.6) of GDEM to demonstrate several significant improvements. The largest change in methodology was ... |

 | How can the United States better support its partners' efforts to combat the threat of weapons of mass destruction (WMD) proliferation? Although the United States has instituted a number of programs to combat the spread of WMD, it does not have the resources necessary to stop all WMD threats. Instead, it needs to pursue a more coordinated effort to enhance partners' border security, WMD detection, interdiction, and other capabilities to ... |

| Relativistic (l MeV) electron flux increases in the Earth's radiation belts are significantly underestimated by models that only include transport and loss processes, suggesting that some additional acceleration process is required. Here we use a new, threedimensional code that includes radial diffusion and quasi-linear pitch angle and energy diffusion due to chorus waves, including cross terms, to simulate the 9 October 1990 magnetic storm. The diffusion coefficients are activity dependent, ... |

However, in order to converge to the global minimum of this cost function,the ocean model (and its adjoint) must be linear. Ocean models, especially those that are designed ... |

| Eigenanalysis of temperature and wind profiles can reveal distinct resonances at mesoscale wavelengths. Fourier transform methods are well suited to analyze resonant modes such as mountain waves due, in part, to (1) their fast computation speed for large wave number domains compared to numerical forecast models and (2) their requirements for only a coarse horizontal background state. Common traits of Fourier mountain wave models include use of the Boussinesq approximation ... |
