Adaptive dim point target detection and tracking infrared imagesDeMars, Thomas V. 12 1900 (has links)
Approved for public release; distribution is unlimited / The thesis deals with the detection and tracking of dim
point targets in infrared images. Research topics include
image process modeling with adaptive two-dimensional Least
Mean Square (LMS) and Recursive Least Squares (RLS) prediction
filters. Target detection is performed by significance
testing the prediction error residual. A pulse tracker is
developed which may be adjusted to discriminate target
dynamics. The methods are applicable to detection and
tracking in other spectral bands. / http://archive.org/details/adaptivedimpoint00dema / Major, United States Marine Corps

Development of a Single-Stage Modulator for Comprehensive Two-Dimensional Gas Chromatography (GC × GC)McNeish, Christopher January 2011 (has links)
The ability to effectively analyze particulate matter (PM2.5) in air is becoming increasingly pertinent. Allen Goldstein of the University of California in Berkeley is studying the semi-volatile fraction of organic compounds in PM2.5 through the use of the thermal desorption aerosol gas chromatograph (TAG) system. However, as conventional GC does not provide adequate separation power, the development of comprehensive two-dimensional gas chromatography (GC × GC) was required. GC × GC works more effectively by utilizing a modulator that periodically traps and focuses analytes from a primary column onto a secondary column. This allows for the primary and secondary columns to separate the analytes based on two different properties.
This report focuses on the continuing study and enhancement of a modulator designed by Ognjen Panić during his Masters project. Improving and testing the robustness of this dual stage modulator was originally the focus of this project. However, this study led to the development of a single stage modulator. In addition to that, the effect of modulator characteristics such as length of the restriction, total length of the modulator and wall thickness on the modulator performance were studied. A robustness test of the single stage modulator was also completed. Experiments conducted tested the characteristics of the new modulator to ensure it performed effectively and would satisfy the requirements of the TAG system. A study comparing the sensitivity of conventional gas chromatography and GC × GC was also preformed. The sensitivity of GC × GC was on average an order of magnitude better than that of 1D GC.

Reversible Attraction-Mediated Colloidal Crystallization on Patterned SubstratesFernandes, Gregory 15 May 2009 (has links)
In this dissertation we used tunable particle-particle and particle-substrate
attraction to achieve reversible two-dimensional crystallization of colloids on
homogeneous and patterned substrates. Total internal reflection and video microscopy
techniques were used to quantify the interparticle and particle-substrate interactions in
these colloidal systems. Equilibrium and dynamic simulations were then utilized to link
these colloidal interactions to the experimental colloidal phase behaviour. The
importance of the nature of the attractive interaction in successfully crystallizing colloids
has also been documented.
The first set of experiments demonstrates the use of temperature and specific ion
effects to reversibly control the net particle-substrate van der Waals (vdW) attraction.
Colloidal stabilization was achieved via the use of adsorbed polymer brush layers. By
using evanescent wave microscopy, we directly and precisely measured how temperature
and specific ion effects control the dimensions of adsorbed polymer layers and hence the
net van der Waals attraction in between the colloids and the substrate. However, the magnitude of the van der Waals attraction decays very rapidly with increasing surface
separation and is therefore not conducive to the self assembly of colloidal crystals.
We successfully used thermoresponsive polymer nanoparticles to control the
depletion attraction between micron sized silica particles and thereby induced reversible
crystallization of the micron sized silica colloids on homogeneous substrates. Video and
evanescent wave microscopy techniques were used to measure the nanoparticle-induced
attractive interaction as a function of temperature. The experimentally observed phase
behaviour was verified via simulations that utilized knowledge of the measured colloidal
depletion interactions.
Finally, patterned surface topologies were used to position attractive colloidal
crystals. Simulations were used to link the measured colloidal interactions to
experimental phase behaviour as well as substrate topology. An extension of the
concepts developed in this dissertation might suggest a general strategy to assemble
colloidal particles into robust and annealable crystals contributing to the fabrication of
photonic bandgap materials.

The study of gene expression induced by manganese of Deinococcus radioduransHuang, Kwun-lun 27 August 2004 (has links)
Deinococcus radiodurans is a highly UV and radio resistant bacterium. The addition of Mn2+ could induce an Mn-CD effect in this bacterium. In this study, we used two-dimensional polyacrylamide gel electrophoresis to compare and analyze the expressed-proteins under various growth conditions, such as temperature and the presence of Mn2+ or not. The results showed that Mn2+ could affect the similarity proteins expression. As the time of Mn-CD effect elapsed longer, the similarity of the proteins from different growth phages became lower. This indicated that Mn2+ indeed could induce or repress the gene expression. From the 2-D gel analysis, there were fourteen proteins had been induced or overexpressed. Five of them were the proteins with the functions for the synthesis and decomposition of proteins and DNA, others were ATP-binding cassette¡]ABC¡^transporter¡Bsuperoxide dismutase[Mn], and the rest five were the hypothetical proteins with unclear function. In addition, this study also found that the cultivation temperatures caused conformational and physiological modification of the cell. The addition of Mn2+ could enhance the viability of the bacterium at higher temperature.
