Color Transparency In Qcd And Post-Selection In Quantum Mechanics, Shmuel Nussinov, Jeff Tollaksen

Mathematics, Physics, and Computer Science Faculty Articles and Research

We discuss color transparency in the nuclear QCD context from the perspective of pre- and post-selected ensembles. We show that the small size of the hadronic states can be explained by the peculiar "force of post-selection," in contrast to the more standard explanation based on external forces.

Monte Carlo Modeling Of Spatial Coherence: Free-Space Diffraction, Donald D. Duncan, David G. Fischer, Scott A. Prahl

Electrical and Computer Engineering Faculty Publications and Presentations

We present a Monte Carlo method for propagating partially coherent fields through complex deterministic optical systems. A Gaussian copula is used to synthesize a random source with an arbitrary spatial coherence function. Physical optics and Monte Carlo predictions of the first- and second-order statistics of the field are shown for coherent and partially coherent sources for free-space propagation, imaging using a binary Fresnel zone plate, and propagation through a limiting aperture. Excellent agreement between the physical optics and Monte Carlo predictions is demonstrated in all cases. Convergence criteria are presented for judging the quality of the Monte Carlo predictions.

Improved Bdfe Using A Priori Information For Turbo Equalization, Jingxian Wu, Sang-Yick Leong, Kah-Ping Lee, Chengshan Xiao, Jan C. Olivier

Electrical and Computer Engineering Faculty Research & Creative Works

Turbo equalization improves communication system performance by iteratively exchanging information between soft-input soft-output (SISO) equalizer and SISO channel decoder. The trellis-based maximum a posteriori probability (MAP) algorithm serves as the optimum SISO equalizer for turbo equalization. However, MAP algorithm is unsuitable for systems with large modulation constellation size and severe inter-symbol interference (ISI) due to its prohibitively high computational complexity. In this paper, an improved SISO block decision feedback equalizer (BDFE) is proposed for low complexity turbo equalization. Unlike other sub-optimum equalizers which perform symbol by symbol detection, the proposed equalizer generates the soft output for each data bit by …

Disintegration, Girardeau A. Spann

Georgetown Law Faculty Publications and Other Works

The silver lining behind the Supreme Court's decision to disintegrate the Seattle and Louisville public schools is that the decision also runs the risk of disintegrating judicial review. Parents Involved in Community Schools v. Seattle School District No. 1 holds that the Constitution bars voluntary, race-conscious efforts by two local school boards to retain the racial integration that they worked so hard to achieve after Brown. In so holding, the Court curiously reads the Equal Protection Clause as preventing the use of race to pursue actual equality, and instead insists on a type of formal "equality" that has historically …

Scrutiny Land, Randy E. Barnett

Georgetown Law Faculty Publications and Other Works

Scrutiny Land is the place where government needs to justify to a court its restrictions on the liberties of the people. In the 1930s, the Supreme Court began limiting access to Scrutiny Land. While the New Deal Court merely shifted the burden to those challenging a law to show that a restriction of liberty is irrational, the Warren Court made the presumption of constitutionality effectively irrebuttable. After this, only one road to Scrutiny Land remained: showing that the liberty being restricted was a fundamental right. The Glucksberg Two-Step, however, limited the doctrine of fundamental rights to those (1) narrowly defined …

The Last Straw: The Department Of Justice's Privilege Waiver Policy And The Death Of Adversarial Justice In Criminal Investigations Of Corporations, Julie R. O'Sullivan

Georgetown Law Faculty Publications and Other Works

The white-collar criminal defense bar has never been reticent to complain about U.S. Department of Justice (DOJ) policies that threaten its clients or the viability of its practice. But nothing--at least in the author's twenty-plus years of involvement in white-collar issues--has consumed the bar as much as the threats posed to the corporate attorney-client privilege and work-product doctrine. While commentators have identified a variety of assaults on these protections, the bar is most vocally outraged by the DOJ policy, pursuant to which, it charges, federal prosecutors regularly insist that corporations waive these protections to secure cooperation credit, declination of criminal …

Climate Change In The Supreme Court, Lisa Heinzerling

Georgetown Law Faculty Publications and Other Works

In Massachusetts v. Environmental Protection Agency, the Supreme Court confronted the issue of climate change for the first time. The Court held that the Clean Air Act gives the Environmental Protection Agency the authority to regulate greenhouse gases and that the agency may not decline to exercise this authority based either on factors not present in the statute or inconclusive gestures toward uncertainty in the science of climate change. I had the privilege of serving as the lead author of the winning briefs in this case. This Article provides an insider's perspective on the choices that went into bringing and …

Development Of A High-Resolution Target Movement Monitoring System For Convergence Monitoring In Mines, Tristan H. Jones

Doctoral Dissertations

"The research performed for this dissertation has been conducted with the goal of developing a ground convergence monitor that may better meet the needs of some mines, leading to increased use of ground monitoring programs and reduced fatality rates from falling and sliding rock. The developed monitor is a convergence monitor capable of achieving sensitivities similar to those of currently available convergence meters such as tape extensometers. The monitor is inexpensive and is capable of totally remote operation in some circumstances...A physical model of the meter was developed based on experimental results and compared to a derived theoretical model to …

Thin Film Techniques For The Fabrication Of Nano-Scale High Energy Density Capacitors, James N. Reck

Doctoral Dissertations

Dielectric thin films of either TiO₂ or BaTiO₃ were sputtered in O₂/Ar plasmas on Si wafers to thicknesses ranging from approximately 25 to 200 nm with patterned Ni or Pt electrodes sputtered in Ar plasmas at thicknesses from about 20 to 250 nm to form nano-capacitors. Statistical design of experiments (DOE) was used to determine the effects of the deposition power, plasma composition, and deposition temperature on the measured electrical properties of the nano-capacitors. Additional tests to determine the effects of the dielectric and electrode thickness on the measured dielectric responses of the devices were also undertaken. Characterization was performed …

Densification, Microstructure, And Mechanical Properties Of Zirconium Diboride Based Ultra-High Temperature Ceramics, Sumin Zhu

Doctoral Dissertations

"The first part of this dissertation was aimed at studying the densification of ZrB₂ ceramics by pressureless sintering techniques. Various processes have been applied to coat ZrB₂ powders with polymer precursors, which were used to produce C after charring. After sintering at 1900⁰C, relative density increased of ~70% for uncoated ZrB₂ to >99% for ZrB₂ coated with at least 1.0 wt% C. Thermodynamic analysis suggested that C reacted with and removed oxide impurities (ZrO₂ and B₂O₃) that were present on the ZrB₂ particle surfaces, which promoted densification by minimizing grain coarsening"--Abstract, page iv.

Technology And Signal Processing For Brain-Machine Interfaces, Justin C. Sanchez, Jose C. Principe, Toshikazu Nishida, Rizwan Bashirullah, John G. Harris, José A.B. Fortes

Electrical and Computer Engineering Faculty Research & Creative Works

Brain-machine interfaces (BMIs) aid disabled humans. BMI systems face challenges such as interfacing with neural tissue, selecting the most appropriate control signals, acquiring data and decoding patient intent in implantable or wearable computers. They must be able to adapt to different variety of behavioral states. Today's hybrid BMI systems consume less power and are made to chronically extract control commands from the nervous system. In terms of signal processing approaches, one challenge for BMI data analysis is learning how to handle large multi-input multi-output systems with signal representations that span continuous and discrete time. BMI systems also need sufficient information …

New Method For Approximating Vague Sets To Fuzzy Sets Based On Voting Model, Jian Liu, Zhizhan Liu, Shunxiang Wu, Yongjian Zhang

Electrical and Computer Engineering Faculty Research & Creative Works

By analyzing Vague Sets voting model, we bring forth a new method for approximating Vague Sets to Fuzzy Sets, and its general process is presented in the article. In a voting model, firstly, we suppose that the abstainers must vote for once more, and the results are close studied. Then the randomicity, uncertainty, and conformity of voting are found. As we know, an abstainer may favor somebody, oppose somebody, or just abstain. In this article, we suppose the distribution of results is consistent with a normal distribution. So, we advance the new approximation method based on Gauss Distribution. © 2008 …

Implementing An Architectural Framework To Define And Deliver Net-Centric Capability To Legacy Military Air Assets Operating Within A System Of Systems, Mark S. Anderson, S. M. Martin, Cihan H. Dagli, Ann K. Miller

Engineering Management and Systems Engineering Faculty Research & Creative Works

The United States Air Force (USAF) is implementing an integrated net-centric system of systems for airborne operations in support of the global war on terror (GWOT). The GWOT demands that a successful architecture framework transforms and delivers net-centric assets to the war-fighter in a timely manner. A critical component of this implementation is the transformation of legacy strategic air platforms into net-centric air power assets operating within a system of systems. The System Architectural (SA) framework, and the Department of Defense Architectural Framework (DoDAF) are ways of managing complexity and organizing information within a system of systems network. This paper …

Estimation Of Earthquake Loss Due To Bridge Damage In The St. Louis Metropolitan Area. Ii: Indirect Losses, David Lee Enke, Chakkaphan Tirasirichai, Ronaldo Luna

Engineering Management and Systems Engineering Faculty Research & Creative Works

An approach to estimate the indirect economic loss due to damaged bridges within the highway system from an earthquake event is presented. The indirect cost considered refers to the increased highway transportation cost only. The study zone covers the St. Louis metropolitan area and its surrounding suburban regions. An earthquake scenario centered in St. Louis, with a magnitude 7.0 is used. The direct earthquake loss was primarily damage to bridges, which causes an increase in travel time and distance within the transportation network. This information is then used as input for the indirect loss model. The indirect loss is examined …

The Effects Of Congressional Elections On Future Equity Market Returns, Vincent Louis Ovlia, David Lee Enke, Michael C. Davis

Engineering Management and Systems Engineering Faculty Research & Creative Works

As the primary entity responsible for new legislation, Congress is capable of enacting legislation that may affect future market returns. To examine potential effects, the percentage of the House of Representatives and Senate controlled by a political party is examined. Additionally, the effect on returns in a change in the percentage of seats gained or lost in Congressional elections is analyzed. To test both theories, a modified “partisan view” model is adopted. Results point to the fact that equity markets perform better in situations in which power is distributed between political parties.

Editorial: Nutrition Research Reviews, Katherine Younger

Articles

We are all familiar with the dietary guideline exhorting us to eat so many portions of oily fish per week in order to boost our intakes of n-3 long-chain PUFA, but it is perhaps not so widely realised that the fish must themselves be provided with dietary n-3 long-chain PUFA or, possibly, their precursors (though, as in humans, the ability of carnivorous fish to elongate and desaturate n-3 PUFA appears to be limited).

Post-Construction Evaluation Of Lime-Treated Soils, Chulmin Jung, Antonio Bobet

JTRP Technical Reports

Lime is used to treat weak subgrade soils during construction of highways. A small amount of lime (4 to 7%) is used to rapidly dehydrate and modify fine grained soils. The modification process improves workability and compactability of the soils. Although the lime modification process is primarily aimed at construction expediency, additional effects such as long-term improvement of stiffness and/or strength by pozzolanic and carbonation cementation reactions are expected. Lime treatment has been employed in Indiana over several decades, but the long-term performance of lime-treated soils has not been well quantified and no field tests have been done on roads …
