The spontaneous polarization of thin film LiNbO$\sb3$ has been shown to be reversible with the application of an electric field at room temperature. This electric field is applied across the sample in the form of a voltage ...

This thesis presents the results of a simulation study of the performance of a message-passing multicomputer using high-speed point-to-point communication links. The multicomputer system consists of IBM RS/6000 machines ...

The activation sequence on the epicardial surface of the in vivo rabbit ventricle has been recorded and analyzed under conditions of normal sinus rhythm and controlled hemodynamic load. Data for the analysis was gathered ...

A new widely tunable mid-infrared (IR) source based on difference-frequency generation (DFG) in Gallium Selenide (GaSe) for use in high-resolution spectroscopy and trace gas detection is described. The characteristics of ...

The theory of continuous wave difference frequency generation (DFG) is studied for a mixing of two waves in a nonlinear medium, the absorption effect of the material is included and optimization conditions are studied. ...

This thesis studies the performance of multistage interconnection networks (MINs) using execution-driven simulation. The networks were studied with varying network configurations, numbers of inputs and outputs of the network ...

A model for simulation of laser produced plasmas that couples absorbed energy, plasma dynamics and radiation pressure was developed. The unusual experimental result of spectral narrowing of reflected laser pulses was ...

The application of diode-laser-pumped tunable IR sources to trace gas detection in air is discussed. The design and technology issues of CW tunable mid-infrared difference-frequency generation are addressed. Feasibility ...

In many computational systems, tasks comprising numerical or symbolic data arrive at a processor periodically. Processing of the $i\sp{th}$ task has to stop before processing of the ($i$ + 1)$\sp{th}$ task begins, causing ...

This thesis develops a software wireless communication testbed which simulates a Code Division Multiple Access (CDMA) link. CDMA is a popular technology in cellular systems due to its superior capacity and performance. The ...
