Physiologically-Based Vision Modeling Applications And Gradient Descent-Based Parameter Adaptation Of Pulse Coupled Neural Networks, Randy P. Broussard
Physiologically-Based Vision Modeling Applications And Gradient Descent-Based Parameter Adaptation Of Pulse Coupled Neural Networks, Randy P. Broussard
Theses and Dissertations
In this research, pulse coupled neural networks (PCNNs) are analyzed and evaluated for use in primate vision modeling. An adaptive PCNN is developed that automatically sets near-optimal parameter values to achieve a desired output. For vision modeling, a physiologically motivated vision model is developed from current theoretical and experimental biological data. The biological vision processing principles used in this model, such as spatial frequency filtering, competitive feature selection, multiple processing paths, and state dependent modulation are analyzed and implemented to create a PCNN based feature extraction network. This network extracts luminance, orientation, pitch, wavelength, and motion, and can be cascaded …

A Qualitative Study Of A College Visual Arts Course: A Multicultural Perspective, Jacqueline A. Badman
A Qualitative Study Of A College Visual Arts Course: A Multicultural Perspective, Jacqueline A. Badman
Theses and Dissertations
The United States is a multicultural place. With its ever increasing cultural and ethnic diversity, multicultural education is important. Since the visual arts have always been produced and perceived within cultures and offer students unique opportunities to explore human expression and experience, the analysis of an introductory art course taught within a multicultural context at a Midwestern university was a sensible starting point. This was especially timely since little research exists in relation to the visual arts taught from a multicultural perspective at the higher education level, and more theoretical works regarding multicultural visual arts exist than do actual studies. …
Distribution And Success Of Galling Insects On Upland Willow (Salix Humilis) In Itasca State Park, Minnesota, Erik J. Harris
Distribution And Success Of Galling Insects On Upland Willow (Salix Humilis) In Itasca State Park, Minnesota, Erik J. Harris
Theses and Dissertations
A comparison was made of the distribution of six galling insects on varying-sized shoots and different ages of their host plant, Salix humilis. Survivorship of the most numerous galler, Iteyomia salicifolia, was used to determine if host use patterns were correlated with galler success. In northern Minnesota, all six gallers were non-randomly distributed among shoots of different length; each occurred at greater numbers than expected on the longest shoots. Two of the six gallers were at higher densities on juvenile ramets of S. humilis, than on mature ones. Densities did not vary between juvenile and mature clones.
A comparison was …

Involvement Of The Amino Terminal Of Actin In Actin-Aldolase Interactions., Tim Jeffrey Keith
Involvement Of The Amino Terminal Of Actin In Actin-Aldolase Interactions., Tim Jeffrey Keith
Theses and Dissertations
Interactions between glycolytic enzymes and cytoskeletal proteins are electrostatic in nature. Studies conducted with derivatizing agents show that the amino side chains of basic amino acids on aldolase interact with carboxyl side chains of acidic amino acids on tubulin. In this study we used the techniques of covalent cross-linking, non-enzymatic cleavage and enzymatic cleavage to determine the amino acids in actin which are involved in the actin-aldolase interaction.Actin and aldolase were covalently cross-linked using the zero length cross-linker 1-ethyl-3- (3-dimethylaminopropyl) -carbodiimide to form a direct covalent link between the two proteins. The cross-linking procedure resulted in the formation of one …

Quantification Of Weather Effects On Imaging Laser Radar, Clifton D. Stargardt
Theses and Dissertations
The Air Force is investigating the use of imaging laser radar systems as autonomous guidance systems on future precision guided munitions. The Air Force's Wright Laboratory is currently testing a 1.06 micron wavelength laser radar (ladar) at Eglin Air Force Base. Since laser radiation can be susceptible to propagation problems through weather, quantitative understanding of these effects is important to the development of this weapon system. Ladar image degradation, in the form of target dropouts and false returns, was evaluated in various weather conditions. Statistical analysis of the images presented expected degrees of degradation according to visibility and rain fall …
Modeling A Chemical Battlefield And The Resulting Effects In A Theater-Level Combat Model, Todd M. Gesling
Modeling A Chemical Battlefield And The Resulting Effects In A Theater-Level Combat Model, Todd M. Gesling
Theses and Dissertations
This thesis describes the development of a methodology to model chemical weapons use in the Joint Staff's Joint Warfare Analysis Experimental Prototype (JWAEP) and to quantify the resulting effects. The methodology incorporates organic unit assets and theater-level chemical assets into JWAEP by using the three principles of nuclear, biological, and chemical defense (NBC) which reflect joint and Army doctrine, and combines them with the basic concepts already used in existing theater-level models. Other aspects of the problem include representing chemical 'packages' on the battlefield, determining attrition and time effects, adjusting unit effectiveness, determining chemical package intelligence acquisition procedures, identifying solution …

In Search Of The Meandering Absolute: The Prints Of Mitzi Humphrey, Mitzi Humphrey
In Search Of The Meandering Absolute: The Prints Of Mitzi Humphrey, Mitzi Humphrey
Theses and Dissertations
Art is more than just a bridge to (or a reflection of) the natural world; it is a natural force in itself. The author is a strong advocate of "artist's prints," prints which are conceived and printed by the artist. She believes that there is a natural sequence of actions and thoughts which cannot be approximated by the substitution of an artist/printer collaboration unless the artist is truly involved with the printer or assistant in every step of the decision-making and mark-making processes.
The prints of this series are not about realistic pictorial space; they are about interior space--that of …

Electrophysiological Effects Of Lysoplasmenylcholine On Rabbit Ventricular Myocytes, Ray Caldwell
Electrophysiological Effects Of Lysoplasmenylcholine On Rabbit Ventricular Myocytes, Ray Caldwell
Theses and Dissertations
Myocardial ischemia activates a phospholipase A2 that targets plasmalogen phospholipids and liberates 1-0-alkenyl-Iysoplasmenylcholine (LPLC) in preference to 1-0- acyl-Iysophosphatidylcholine (LPC). Although LPC is a pro arrhythmic ischemic metabolite, the effect of LPLC on cardiac electrophysiology is unknown. At the lowest doses investigated, LPLC induced spontaneous contractions in otherwise quiescent rabbit ventricular myocytes significantly faster than LPC. Spontaneous contractions developed with median times of 16.4 (n = 64), 27.4 (n = 36), and >60 min (n = 25) during exposure to 5, 2.5, and 1 JlM LPLC compared with 38.0 (n = 48) and >60 min (n = 29) for 5 …
