| Discussions of U.S. and global energy supply refer to oil, natural gas, and coal using several terms that may be unfamiliar to some. The terms used to describe different types of fossil fuels have technically precise definitions, and misunderstanding or misuse of these terms may lead to errors and confusion in estimating energy available or making comparisons among fuels, regions, or nations. Fossil fuels are categorized, classified, and named using ... |

| Like High Altitude Electromagnetic Pulse (HEMP), high power microwaves (HPM) produce intense energies, which may overload or damage various electrical system components such as microcircuits. This thesis investigates possible effects of a hypothetically designed HEMP-like weapon, an e-bomb, on electronically equipped target systems. The procedure to determine these possible effects is to estimate the electromagnetic coupling from first principles and simulations using a coupling model program (CEMPAT), pursuing a feasible ... |

| Wireless distributed microsensor systems offer reliable monitoring and control of a myriad of applications ranging from machine state and perimeter security to nuclear/chemical/biological and other military applications. Historically, batteries have supplied power to mobile, embedded, and ultra-low power microsensors. While there are many obvious short-term advantages of using batteries, they do have a long-term negative environmental impact. An alternative to batteries exists in harnessing the ambient energy surrounding the system ... |

|
| We calculate the energy decay rate of Josephson qubits and superconducting resonators from nonequilibrium quasiparticles. The decay rates from experiments are shown to be consistent with predictions based on a prior measurement of the quasiparticle density nqp 10=micrometers3, which suggests that nonequilibrium quasiparticles are an important decoherence source for Josephson qubits. Calculations of the energy-decay and diffusion of quasiparticles also indicate that prior engineered gap and trap structures, which reduce ... |
