Cmos Image Sensor With Bi-Directional Column Sensor, Philip D. Thorpe Ii

Theses

CMOS image sensors have been around since the 1960's. However due to poor light sensitivity and poor signal-to-noise ratios (SNR) the architecture was not popular. Since then many improvements have been made to the architecture, making camera designs that use CMOS imagers more prevalent. Much of the improvement in SNR has been due to fixed-pattern noise reduction. Correlated double sampling (CDS) is a popular technique to reduce the effects of this source of noise. The circuitry required to implement CDS can be complex and hinders other areas of an image sensor performance in some schemes. This thesis proposes a new …

Jointly Hyponormal Pairs Of Commuting Subnormal Operators Need Not Be Jointly Subnormal, Raúl E. Curto, Jasang Yoon

School of Mathematical & Statistical Sciences Faculty Publications

We construct three different families of commuting pairs of subnormal operators, jointly hyponormal but not admitting commuting normal extensions. Each such family can be used to answer in the negative a 1988 conjecture of R. Curto, P. Muhly and J. Xia. We also obtain a sufficient condition under which joint hyponormality does imply joint subnormality.

Recent Developments In Understanding Two-Dimensional Turbulence And The Nastrom-Gage Spectrum, Eleftherios Gkioulekas, Ka Kit Tung

School of Mathematical & Statistical Sciences Faculty Publications

Two-dimensional turbulence appears to be a more formidable problem than three-dimensional turbulence despite the numerical advantage of working with one less dimension. In the present paper we review recent numerical investigations of the phenomenology of two-dimensional turbulence as well as recent theoretical breakthroughs by various leading researchers. We also review efforts to reconcile the observed energy spectrum of the atmosphere (the spectrum) with the predictions of two-dimensional turbulence and quasigeostrophic turbulence.

Quantum Dot Potentials: Symanzik Scaling, Resurgent Expansions, And Quantum Dynamics, Andrey S. Surzhykov, Michael Lubasch, Jean Zinn-Justin, Ulrich D. Jentschura

Physics Faculty Research & Creative Works

This article is concerned with a special class of the "double-well- like" potentials that occur naturally in the analysis of finite quantum systems. Special attention is paid, in particular, to the so-called Fokker-Planck potential, which has a particular property: the perturbation series for the ground-state energy vanishes to all orders in the coupling parameter, but the actual ground-state energy is positive and dominated by instanton configurations of the form exp (-a g), where a is the instanton action. The instanton effects are most naturally taken into account within the modified Bohr-Sommerfeld quantization conditions whose expansion leads to the generalized perturbative …

Constitutional Crisis In The Commonwealth: Resolving The Conflict Between Governors And Attorneys General, Michael Signer

University of Richmond Law Review

In this article, I argue the solution to agency conflict and the broader problem of establishing the proper scope of executive authority lies in establishing that Virginia has a "statutory" rather than a "common-law" model of the Attorney General's powers, and that the Office of the Attorney General is therefore circumscribed by statute. Contrary to popular understanding, I will argue that Wilder v. Attorney General of Virginia effectively establishes Virginia as a statutory state and resolves the conflict in favor of the Governor. Because the Supreme Court of Virginia is unlikely to act more strongly in favor of the statutory …

Low Voltage Electrochemical Hydrogen Production, Eric P. Weaver

USF Tampa Graduate Theses and Dissertations

Hydrogen production is dependent on natural gas, 90% in the U.S. and 48% of the world’s production. Natural gas supply is dwindling and it’s price is increasing. Greenhouse gases and air pollutants are emitted when natural gas is used. In a single product production facility, coal is not competitive with natural gas for hydrogen production at current prices. Hydrogen production by direct electrochemical dissociation of water requires a relatively high voltage.

Techniques have been developed for manufacturing hydrogen as a lucrative byproduct of IGCC electric power generation, refinery sulfur production and sulfuric acid production for fertilizer production. Laboratory experiments have …

The Nato-Russia Partnership: A Marriage Of Convenience Or A Troubled Relationship?, Stephen J. Blank Dr.

Books, Monographs & Collaborative Studies

Four years after the NATO-Russia Council came into being, it represents a picture in ambivalence and incomplete realization of partnership. This monograph focuses on the Russian side of this growing estrangement. It finds the Russian roots of this ambivalence or alienation in the increasingly visible manifestations of an autocratic and neo-imperial Russian state and foreign and defense policy. These strong trends in Russian policy inhibit the formation of a genuine security partnership that can provide for Eurasian security in the face of multiple contemporary threats. Indeed, it is debatable whether Russia really wants a comprehensive partnership with NATO. The author …

Transmission Electron Goniometry And Its Relation To Electron Tomography For Materials Science Apoplications, Peter Moeck, P. Fraundorf

Physics Faculty Publications and Presentations

Aspects of transmission electron goniometry are discussed. Combined with high resolution phase contrast transmission electron microscopy (HRTEM) and atomic resolution scanning TEM (STEM) in the atomic number contrast (Z-STEM) or the phase contrast bright field mode, transmission electron goniometry offers the opportunity to develop dedicated methods for the crystallographic characterization of nanocrystals in three dimensions. The relationship between transmission electron goniometry and electron tomography for materials science applications is briefly discussed. Internet based java applets that facilitate the application of transmission electron goniometry for cubic crystals with calibrated tilt-rotation and double-tilt specimen holders/goniometers are mentioned. The so called cubic-minimalistic tilt …

On The Effective Communication Of The Results Of Empirical Studies, Part Ii, Lee Epstein, Andrew D. Martin, Matthew M. Schneider

Vanderbilt Law Review

In an important and certainly timely article published in the N.Y. U. Law Review, Nancy C. Staudt demonstrates that, in taxpayer standing cases, judges are motivated by politics but can be constrained when the law is clear and oversight exists. As part of that demonstration, Professor Staudt offers an empirical analysis of the decision to grant standing to federal taxpayers-the results of which we reproduce in Table 1.2

What are we to make of this rather ominous-looking table? Professor Staudt suggests two key takeaways. First, the analysis, she reports, shows that doctrine helps explain standing decisions even when political factors …

Juror Questions During Trial: A Window Into Juror Thinking, Shari Seidman Diamond, Mary R. Rose, Beth Murphy, Sven Smith

Vanderbilt Law Review

The jury has undergone a dramatic transformation from its earliest incarnation when jurors acted as witnesses, investigators, and tribunal. In the modern American jury trial, the parties determine what jurors learn during the proceedings. Jurors of today, assigned the role of audience members until deliberations begin, typically speak in the courtroom only during jury selection and through their verdict at the end of the trial. In light of their enforced silence throughout the trial, jurors have no opportunity to clarify or check on their interpretation of the evidence and they provide few external indications about their thinking as the trial …

In Texas, Life Is Cheap, Frank Cross, Charles Silver

Vanderbilt Law Review

What is the life of a Texan worth? Some might suggest very little. Payments in thousands of tort cases in which Texans died provide some evidence for this hypothesis. Although Texas has been a focus of much of the national controversy over the costs of tort litigation, payments in death cases have seen relatively little disciplined research. Existing research often misses the primary effect of the system because it focuses on trial outcomes rather than settlement payments. This Article provides some evidence of the actual payments made in Texas in death cases, their determinants, and the implications of those findings …

Through a unique series of events, I was selected and attended the Brazilian Army's ECEME, a ten-month CGSC equivalent, where I studied brigade and division-level operations through the lens of a foreign military. This rare opportunity not only afforded me a unique and valuable professional development experience, it …

Tuition Reduction Incentive Program Application (Compuscrip), Steve Williams

Masters Theses & Doctoral Dissertations

Often, private organizations such as schools, clubs, and non-profits operate on modest budgets in order to keep tuition, dues, or other types of fees associated with their organization affordable for its members. An option to help supplement tuition costs or fees is for the organization to partner with local businesses that will provide a "kick back" to the organization or members for purchasing debit cards from the businesses. The standard/generic term for this type of program is SCRIP. SCRIP is "a Latin term that means anything used instead of money" (United Scrip). This paper will describe a plan to create …

Buccal And Palatal Talon Cusps With Pulp Extensions On A Supernumerary Primary Tooth, Esin Siraci, H. Cem Güngör, Zafer C. Cehreli, B. Taner

School of Dentistry Faculty Research and Publications

This paper reports an unusual occurrence of talon cusp on a supernumerary primary incisor, presenting on both labial and palatal sides. The tooth was scheduled for extraction due to its interference with the occlusion. Morphometric analysis of the taloned cusps was performed on digitized replicas of the tooth crown using open-source image analysis toolkit (ImageJ). Further non-destructive investigation of the taloned crown under cone-beam X-ray computed tomography revealed pulpal extensions in both talon cusps.

Fluorescence Polarization Of Helium Negative-Ion Resonances Excited By Polarized Electron Impact, J. W. Maseberg, Timothy J. Gay

Timothy J. Gay Publications

We have investigated helium (1s3d) ³D → (1s2p) ³P (588 nm) fluorescence produced by electron impact excitation in the vicinity of the (2s²2p) ²P and (2s2p²) ²D negative-ion resonances at 57.2 and 58.3 eV, respectively. In contrast to previous work, we use spin-polarized incident electrons and report the relative Stokes parameters P₁, P₂, and P₃ in the 55–60 eV region. Our failure to see discernable resonance effects in P₂ indicates that even though the lifetime of these resonances is significant (~10 fs), magnetic forces acting on …

Production Of Excited Atomic Hydrogen And Deuterium From H2 And D2 Photodissociation, J. D. Bozek, J. E. Furst, Timothy J. Gay, H. Gould, A. L. D. Kilcoyne, J. R. Machacek, F. Martin, K. W. Mclaughlin, J. L. Sanz-Vicario

Timothy J. Gay Publications

We have measured the production of both Lyα and Hα fluorescence from atomic H and D for the photodissociation of H₂ and D₂ by linearly polarized photons with energies between 24 and 60 eV. In this energy range, excited photofragments result primarily from the production of doubly excited molecular species which promptly autoionize or dissociate into two neutrals. Our data are compared with ab initio calculations of the dissociation process, in which both doubly excited state production and prompt ionization (non resonant) channels are considered. Agreement between our experimental data and that of earlier work, and with our …

Multi-User Uwb-Ir Systems With Interleaved Coding-Modulation On Multipath Fading Channels, Michal M. Pietrzyk, Keni Popovski, Tadeusz Wysocki, Beata J. Wysocki, Jos H. Weber

Department of Electrical and Computer Engineering: Faculty Publications (to 2015)

Interleaved coding-modulation (ICM) is a recently proposed method for ultra-wideband impulse radio (UWBIR) systems. ICM exploits the concept of chip interleaving, allowing to alleviate the problem of inter-symbol and inter-pulse interference commonly present in high data rate UWB-IR systems. In this paper, we extend previous work on ICM to scarcely populated multi-user scenarios. We propose a design of a deterministic chip interleaver based on time-hopping hyperbolic congruence sequences. We also review the main parameters of the random and hyperbolic interleavers. Our results indicate that the proposed type of interleaver yields similar performance to random interleavers but with the advantage of …

A Rhetoric For Ratification: The Argument Of The Federalist And Its Impact On Constitutional Interpretation, Dan T. Coenen

Duke Law Journal

Courts, lawyers, and scholars have long assumed that The Federalist Papers supply important information for use in constitutional argument and interpretation. In recent years, commentators have questioned this view. Their skepticism grows out of two major concerns. First, Justice Scalia's challenge to the use of legislative history in the statutory context casts a cloud over judicial use of background texts such as The Federalist in seeking the meaning of the Constitution. Second, even if courts may rely on some background materials in interpreting the Constitution, there is reason to conclude that The Federalist. does not qualify as the sort of …

Further Evidence For Variable Synchrotron Emission In Xte J1118+480 In Outburst, Robert I. Hynes, Edward L. Robinson, Kevin J. Pearson, Dawn M. Gelino, Wei Cui, Yongquan Xue, Matt A. Wood, Todd K. Watson, Don Earl Winget, Isaac M. Silver

Aerospace, Physics, and Space Science Faculty Publications

We present simultaneous multicolor infrared and optical photometry of the black hole X-ray transient XTE Jill 8+480 during its short 2005 January outburst, supported by simultaneous X-ray observations. The variability is dominated by short timescales, ∼10 s, although a weak superhump also appears to be present in the optical. The optical rapid variations, at least, are well correlated with those in X-rays. Infrared JHKS photometry, as in the previous outburst, exhibits especially large-amplitude variability. The spectral energy distribution (SED) of the variable infrared component can be fitted with a power law of slope α = -0.78 ± 0.07, where Fᵧ …

Analysis Of Free Drug Fractions Using Near-Infrared Fluorescent Labels And An Ultrafast Immunoextraction/Displacement Assay, Corey M. Ohnmacht, John E. Schiel, David S. Hage

David Hage Publications

A chromatographic method was developed for measuring free drug fractions based on the use of an ultrafast immunoextraction/displacement assay (UFIDA) with near-infrared (NIR) fluorescent labels. This approach was evaluated by using it to determine the free fraction of phenytoin in serum or samples containing the binding protein human serum albumin (HSA). Items considered in the design of this method included the dissociation rate of HSA-bound phenytoin, the rate of capture of free phenytoin by immunoextraction microcolumns, the behavior of NIR fluorescent labels in a displacement format, and the overall response and stability of the resulting assay. In the final UFIDA …
