Observation Of And Model For Nonlinear Mode Conversion In A Non-Neutral Plasma, Grant W. Hart, Bryan G. Peterson, Ross L. Spencer Jul 2003

Observation Of And Model For Nonlinear Mode Conversion In A Non-Neutral Plasma, Grant W. Hart, Bryan G. Peterson, Ross L. Spencer

Faculty Publications

The nonlinear interaction of the two lowest Trivelpiece-Gould modes in a non-neutral plasma has been observed. Because of coupling in the nonlinear terms of the continuity and momentum equations, the two modes can exchange energy and convert one to the other. This can be modeled using the cold fluid equations and the averaging method. Experimentally, this process always stops with the lower frequency mode dominating the final state. Numerical integration of the model suggests that this occurs because the higher frequency mode is more strongly damped than the lower frequency mode.

Quality Of Dehydrated Whole Egg Packaged In No. 10 Cans, T.A. Gnadt, Lynn V. Ogden, Oscar A. Pike Jul 2003

Quality Of Dehydrated Whole Egg Packaged In No. 10 Cans, T.A. Gnadt, Lynn V. Ogden, Oscar A. Pike

Faculty Publications

Dehydration reduces egg mass and increases shelf-life without significantly affecting most functional properties. This has created a demand for dehydrated whole egg in military rations, emergency relief programs and personal storage. However, because such products are usually stored before use, the buyer may be unaware of product quality until long after purchase. The purpose of this study was to investigate the quality of several brands of dehydrated whole egg commercially packaged in No. 10 cans. Eight brands of dehydrated whole egg were obtained from food retailers. All but 1 brand were labeled as having a low oxygen environment. A 50 …

Focusing Of Spin Polarization In Semiconductors By Inhomogeneous Doping, Yuriy V. Pershin Dr, Vladimir Privman Jun 2003

Focusing Of Spin Polarization In Semiconductors By Inhomogeneous Doping, Yuriy V. Pershin Dr, Vladimir Privman

Faculty Publications

We study the evolution and distribution of nonequilibrium electron spin polarization in n-type semiconductors within the two-component drift-diffusion model in an applied electric field. Propagation of spin-polarized electrons through a boundary between two semiconductor regions with different doping levels is considered.We assume that inhomogeneous spin polarization is created locally and driven through the boundary by the electric field.We show that an initially created narrow region of spin polarization can be further compressed and amplified near the boundary. Since the boundary involves variation of doping but no real interface between two semiconductor materials, no significant spin polarization loss is expected. …

A Self-Retracting Fully Compliant Bistable Micromechanism, Nathan D. Masters, Larry L. Howell Jun 2003

A Self-Retracting Fully Compliant Bistable Micromechanism, Nathan D. Masters, Larry L. Howell

Faculty Publications

A new class of fully compliant bistable mechanisms with the added benefit of integrated self-retraction has been developed (hereafter identified as Self-Retracting Fully compliant Bistable Mechanism or SRFBM). A technique using tensural pivots to manage compressive loading in compliant mechanisms is introduced and implemented in the SRFBM. The elimination of traditional kinematic joints and their associated clearance allows a total displacement between stable positions of 8.5 m, and the mechanism size is less than 300 m square when using 2.0 m minimum line widths. Maximum actuation force is approximately 500 N. The SRFBM's small linear displacement and reasonable actuation force …

Minimal Graphs In R3 Over Convex Domains, Michael Dorff Jun 2003

Minimal Graphs In R3 Over Convex Domains, Michael Dorff

Faculty Publications

Krust established that all conjugate and associate surfaces of a minimal graph over a convex domain are also graphs. Using a convolution theorem from the theory of harmonic univalent mappings, we generalize Krust's theorem to include the family of convolution surfaces which are generated by taking the Hadamard product or convolution of mappings. Since this convolution involves convex univalent analytic mappings, this family of convolution surfaces is much larger than just the family of associated surfaces. Also, this generalization guarantees that all the resulting surfaces are over close-toconvex domains. In particular, all the associate surfaces and certain Goursat transformation surfaces …

Religiousness And Depression: Evidence For A Main Effect And The Moderating Influence Of Stressful Life Events, Timothy B. Smith, Michael E. Mccullough, Justin Poll Jun 2003

Religiousness And Depression: Evidence For A Main Effect And The Moderating Influence Of Stressful Life Events, Timothy B. Smith, Michael E. Mccullough, Justin Poll

Faculty Publications

The association between religiousness and depressive symptoms was examined with meta-analytic methods across 147 independent investigations (N = 98,975). Across all studies, the correlation between religiousness and depressive symptoms was –.096, indicating that greater religiousness is mildly associated with fewer symptoms. The results were not moderated by gender, age, or ethnicity, but the religiousness–depression association was stronger in studies involving people who were undergoing stress due to recent life events. The results were also moderated by the type of measure of religiousness used in the study, with extrinsic religious orientation and negative religious coping (e.g., avoiding difficulties through religious activities, …

Effects Of Solvent Model Flexibility On Aqueous Electrolyte Behavior Between Electrodes, Richard L. Rowley, John N. Harb, Clint G. Guymon, Matthew L. Hunsaker, Douglas Henderson Jun 2003

Effects Of Solvent Model Flexibility On Aqueous Electrolyte Behavior Between Electrodes, Richard L. Rowley, John N. Harb, Clint G. Guymon, Matthew L. Hunsaker, Douglas Henderson

Faculty Publications

Molecular dynamics simulations have been carried out for aqueous electrolyte solutions between model electrode surfaces. The effect of solvent model flexibility on bult and double layer properties was observed for electrode surface charge densities of 0, 0.1 and 0.2 and ion concentrations of 0, 0.5 and 1 M. Two flexible models were used to isolate the effects of flexibility from the effects of a change in the condensed-phase dipole moment. Model flexibility increases the pure water self-diffusion coefficient while a larger liquid diple moment substantially decreases it. There is an increase in ion contact adsorption and counter ion affinity with …

A Self-Adapting Healthcare Information Infrastructure Using Mobile Computing Devices, James K. Archibald, Eric S. Hall, Charles D. Knutson, David K. Vawdrey Jun 2003

A Self-Adapting Healthcare Information Infrastructure Using Mobile Computing Devices, James K. Archibald, Eric S. Hall, Charles D. Knutson, David K. Vawdrey

Faculty Publications

Despite recent improvements in the gathering and sharing of patient medical information among healthcare providers, there remains a gap in the electronic medical record infrastructure. Patient data is not available in some situations, either because the infrastructure is inaccessible (as in a natural disaster) or because there is no way to link the patient to the infrastructure (e.g., the patient cannot supply necessary identification information). This paper describes the Poket Doktor System, an architecture that allows an individual to carry personal electronic medical information on a wireless handheld device such as a smart card, cell phone, or PDA. Medical workers …

Can All Beings Potentially Attain Awakening? Gotra-Theory In The Mahāyānasūtrālaṃkāra, Mario D'Amato Jun 2003

Can All Beings Potentially Attain Awakening? Gotra-Theory In The Mahāyānasūtrālaṃkāra, Mario D'Amato

Faculty Publications

Given that for the MSA/Bh gotra is indicative of a sentient being’s soteriological potentiality, an important issue is whether gotra is able to be acquired by every sentient being or whether there are some beings who are excluded from ever acquiring a gotra; and furthermore if some beings are excluded, in what sense they are excluded . It will be necessary to understand these issues in order to address the question of whether, from the perspective of the MSA/Bh, all sentient beings can potentially attain awakening. And so I will begin by discussing the meanings of the term gotra in …

Thermal Management Of Algan-Gan Hfets On Sapphire Using Flip-Chip Bonding With Epoxy Underfill, Jie Sun, H. Fatima, Alexei Koudymov, A. Chitnis, X. Hu, H.-M Wang, J. Zhang, Grigory Simin, J. Yang, Asif Khan Jun 2003

Thermal Management Of Algan-Gan Hfets On Sapphire Using Flip-Chip Bonding With Epoxy Underfill, Jie Sun, H. Fatima, Alexei Koudymov, A. Chitnis, X. Hu, H.-M Wang, J. Zhang, Grigory Simin, J. Yang, Asif Khan

Faculty Publications

Self-heating imposes the major limitation on the output power of GaN-based HFETs on sapphire or SiC. SiC substrates allow for a simple device thermal management scheme; however, they are about a factor 20-100 higher in cost than sapphire. Sapphire substrates of diameters exceeding 4 in are easily available but the heat removal through the substrate is inefficient due to its low thermal conductivity. The authors demonstrate that the thermal impedance of GaN based HFETs over sapphire substrates can be significantly reduced by implementing flip-chip bonding with thermal conductive epoxy,underfill. They also show that in sapphire-based flip-chip mounted devices the heat …

That Every Man Might Speak In The Name Of God The Lord: A Study Of Official Declaration 2, Richard Bennett Jun 2003

That Every Man Might Speak In The Name Of God The Lord: A Study Of Official Declaration 2, Richard Bennett

Faculty Publications

Official Declaration 2, tucked away quietly at the very tail end of the Doctrine and Covenants, is in many ways a fitting conclusion to the preface of the Doctrine and Covenants recorded 147 years before. In section 1 the Lord reveals much about the Restoration and about the divine pulley of the First Vision in particular. The term pulley emphasizes the two-way nature of the First Vision, for although Joseph prayed to know heaven's will, God "called upon" his servant to initiate the Restoration. Although much has been said about the boy prophet's request, surely God's intent counts for just …

Dynamic Joint Action Perception For Q-Learning Agents, Nancy Fulda, Dan A. Ventura Jun 2003

Dynamic Joint Action Perception For Q-Learning Agents, Nancy Fulda, Dan A. Ventura

Faculty Publications

Q-learning is a reinforcement learning algorithm that learns expected utilities for state-action transitions through successive interactions with the environment. The algorithm's simplicity as well as its convergence properties have made it a popular algorithm for study. However, its non-parametric representation of utilities limits its effectiveness in environments with large amounts of perceptual input. For example, in multiagent systems, each agent may need to consider the action selections of its counterparts in order to learn effective behaviors. This creates a joint action space which grows exponentially with the number of agents in the system. In such situations, the Q-learning algorithm quickly …

Image Segmentation With Ratio Cut, Song Wang, Jeffrey Mark Siskind Jun 2003

Image Segmentation With Ratio Cut, Song Wang, Jeffrey Mark Siskind

Faculty Publications

This paper proposes a new cost function, cut ratio, for segmenting images using graph-based methods. The cut ratio is defined as the ratio of the corresponding sums of two different weights of edges along the cut boundary and models the mean affinity between the segments separated by the boundary per unit boundary length. This new cost function allows the image perimeter to be segmented, guarantees that the segments produced by bipartitioning are connected, and does not introduce a size, shape, smoothness, or boundary-length bias. The latter allows it to produce segmentations where boundaries are aligned with image edges. Furthermore, the …

Ethnic Identity And Racial Attitudes In A Minority Group Of Mixed Racial Origin, Timothy B. Smith, Joy Stratton, Christopher R. Stones, Anthony Naidoo May 2003

Ethnic Identity And Racial Attitudes In A Minority Group Of Mixed Racial Origin, Timothy B. Smith, Joy Stratton, Christopher R. Stones, Anthony Naidoo

Faculty Publications

Limited information exists on the racial attitudes and ethnic identities of groups of mixed racial origin. The present research tested the hypotheses that the construct of ethnic identity is valid among such groups and that ethnic identity is related to out-group prejudice, as predicted by social identity theory. The Multigroup Ethnic Identity Measure, the Anti-White Scale, and the Subtle Racism Scale were administered to 70 South Africans of mixed racial decent, the so-called Coloureds. A factor analysis supported the structural validity of the measure of ethnic identity with this sample, but correlations between scales did not support the prediction that …
