In this thesis I consider a scheme for quantum computation in which quantum bits (qubits) are stored in individual spectral holes of an in homogeneously broadened medium, such as a cryogenically cooled crystal of Pr:Y2 SiO ...

With the ever-increasing ubiquity of mobile consumer electronic devices comes the rising demand for portable electric power. Current battery technology gives a very modest energy return per weight or volume. Hydrocarbons ...

ASCA is a broad band (0.3 - 12 keV) x-ray astrophysical observatory in which various instruments operate with high throughput and high spectral resolution. Detailed examination of the method in which photoelectronic ...

Vector field visualization is a useful tool in science and engineering, giving us a powerful way of understanding the structure and evolution of the field. A fairly recent technique called Line Integral Convolution (LIC) ...

A periodic arrangement of atoms in a crystal presents a periodic potential for electrons. The bragg diffraction of electrons from the atoms may lead to a band gap, which represents a range of frequencies the electrons ...

This thesis describes tracking objects with low-level electric fields. A physical model is presented that describes the important interactions and the required mathematical inversions. Sophisticated hardware used to perform ...
