System identification for robust control
(1998)
In the design of a robust control system, one needs a nominal model together with a quantitative bound on the uncertainty that results from under-modeling and disturbances. In this thesis we do not intentionally seek a ...
Longitudinal recording on FePt and FePtX (X = B, Ni) intermetallic compounds
(1999)
Near field recording on high coercivity FePt intermetallic compound media using a high Bsat write element was investigated. Untextured FePt media were prepared by magnetron sputtering on ZrO2 disks at a substrate temperature ...
Low-frequency noise in spin valve sensors
(1999)
Low frequency noise in giant magnetoresistive spin valves has been studied as a means of optimizing signal to noise ratios and characterizing device performance. The devices studied were sputter deposited NiFe/Cu/NiFe/FeMn ...
Optical characterization of lithium niobate thin film waveguides sputtered on sapphire substrates
(1991)
Thin films of lithium niobate on various oriented sapphire substrates were fabricated by the rf sputtering method. Polarized He-Ne laser light with a wavelength of 6328 A was successfully coupled into the optical waveguides ...
Statistical and biophysical modeling of binaural interaction in the lateral superior olive
(1996)
The Lateral Superior Olive (LSO) is believed to be involved in encoding high frequency localization information based on interaural level difference (ILD) and interaural time difference (ITD) cues. Details of how this ...
Functionalization of scanning tunneling microscope probes with buckminsterfullerenes
(1996)
This dissertation analyzes the feasibility and advantages of molecular functionalization of scanning tunneling microscope (STM) probes with buckminsterfullerenes. The C$\sb{60}$ molecules are adsorbed onto the tunneling ...
Pulsed ultraviolet laser ablation: Theoretical considerations and applications in medicine
(1990)
Pulsed ultraviolet lasers can be used to induce clean etching in organic and some inorganic materials. This effect is called photoablation or ablative photodecomposition. Although the precise cause remains unknown, this ...
Generation of broad bandwidth UV pulses via sum frequency mixing
(1994)
Focusing effects on phase front curvature are important in determining the band-width generated in the near vacuum ultraviolet by sum frequency mixing of ultrashort pulses. Noncollinear sum frequency mixing is utilized to ...
Methods of electrically characterizing zinc selenide epitaxial layers on gallium arsenide substrates
(1994)
A number of different methods for electrically characterizing ZnSe thin films are presented. These include the Hall effect, current-voltage profiling, and capacitance-voltage profiling. The planar Schottky technique is ...
Development of a high power, ultrashort pulse laser system
(1990)
This work focuses on the development of a new high power, ultrashort pulse dye laser system based on solid state Nd:YAG pump sources for a synchronously pumped dye laser and a series of dye amplifiers. This system will be ...
