Image Processing Based Control For Scaled Automated Vehicles, N. Schlegel, Pushkin Kachroo, Joseph A. Ball, J. S. Bay

Electrical & Computer Engineering Faculty Research

This paper presents a way to design a lateral controller for an automated vehicle using information gained through image processing with the control objective being to stay on a desired path. Two possible ways to obtain the information necessary for lateral control by image processing are presented, one based on pixel intensity summation and the other on vanishing point calculations. The paper also describes two algorithms for the actual lateral control, one based on classical control theory and the other on modern H∞ control. The resulting control algorithms were implemented on a scaled autonomous vehicle system.

Modeling And Control Of Electromagnetic Brakes For Enhanced Braking Capabilities For Automated Highway Systems, Ming Qian, Pushkin Kachroo

Electrical & Computer Engineering Faculty Research

In automatic highway systems, a faster response and a robust braking system are crucial part of the overall automatic control of the vehicle. This paper describes electromagnetic brakes as a supplementary system for regular brakes. This system provides better time for emergency situations, and in general keeps the friction brake working longer and safer. A modified mathematical model for electromagnetic brakes is proposed to describe their static characteristics (angular speed versus brake torque). The performance of the modified mathematical model is better than the other three models available in the literature. To control the brakes, a robust sliding mode controller …

Making Constitutional Doctrine In A Realist Age, Victoria Nourse

Georgetown Law Faculty Publications and Other Works

In this article the author considers three examples of modern constitutional doctrine that show how judges have stolen bits and pieces from popularized skepticisms about the job of judging and have molded this stolen rhetoric into doctrine. In the first example, she asks whether constitutional law's recent penchant for doctrinal rules based on "clear law" could have existed without the modern age's obsession with legal uncertainty. In the second, the author considers whether our contemporary rhetoric of constitutional "interests" and "expectations" reflects modern critiques of doctrine as failing to address social needs. In the third, she asks how an offhand …

Was Slavery Unconstitutional Before The Thirteenth Amendment? Lysander Spooner’S Theory Of Interpretation, Randy E. Barnett

Georgetown Law Faculty Publications and Other Works

In 1843, radical abolitionist William Lloyd Garrison called the Constitution of the United States, "a covenant with death and an agreement with hell." Why? Because it sanctioned slavery, one of the greatest crimes that one person can commit against another. Slavery was thought by abolitionists to be a violation of the natural rights of man so fundamental that, as Lincoln once remarked: "If slavery were not wrong, nothing is wrong." Yet the original U.S. Constitution was widely thought to have sanctioned this crime. Even today, many still believe that, until the ratification of the Thirteenth Amendment prohibiting involuntary servitude, slavery …

Timing Of Basaltic Volcanism Along The Mesa Butte Fault In The San Francisco Volcanic Field, Arizona, From 40Ar/39Ar Dates: Implications For Longevity Of Cinder Cone Alignments, F. M. Conway, David A. Ferrill, Chris M. Hall, Alan P. Morris, John A. Stamatakos, Charles B. Connor, Alex N. Halliday, Christopher Condit

School of Geosciences Faculty and Staff Publications

Using high‐precision stepwise‐heating 40Ar/39Ar methods, we dated volcanic products of at least 12 vents cropping out along the northern segment of the Mesa Butte Fault in the San Francisco Volcanic Field, Arizona, where the relationship between fault and vent alignment is unambiguous. The 40Ar/39Ar isochron dates indicate that the Mesa Butte Fault hosted five episodes of volcanism over a 1 million year interval, from 1400 to 300 ka. The first episode occurred 1 km northwest of the trace of the Mesa Butte Fault, whereas the next two episodes were centered near the intersection of the Mesa Butte and Cedar Ranch …

Can We Indict A Sitting President?, Susan Low Bloch

Georgetown Law Faculty Publications and Other Works

This symposium addresses the difficult question of whether a President can be criminally prosecuted while still in office or whether indictment and prosecution must await his leaving. The question is difficult because the text of the Constitution gives us some hints but no dispositive answers. At first reading, Section 3 of Article I seems to suggest that impeachment must precede any criminal prosecution: "Judgment in Cases of Impeachment shall not extend further than to removal from Office, and disqualification to hold and enjoy any Office of honor, Trust, or Profit under the United States; but the Party convicted shall nevertheless …

Hrotswitha Of Gandersheim's Dulcitius And Callimachus In A New Translation, Mark L. Damen

Quidditas

Even without external corroborating evidence, we may infer from her works that the nun Hrotswitha (Hrotsvit in Saxon) lived in Saxony during the second half of the tenth century. Because she seems to have had considerable freedom of movement and expression for a woman at that time, writing about worldly affairs evidently with some personal knowledge of them, she was most likely a canoness, that is, not fully cloistered. She must have visited the courts of the Saxon kings, probably more than once, since she chronicles their exploits and composes poetry of a type briefly popularized by a scholar in …

Demythifying Multicultural Education: Social Semiotics As A Tool Of Critical Pedagogy, Stephanie Urso Spina

Publications and Research

This article discusses the assumptions and curricular implications of a social semiotic approach to education. Semiotics refers to the meaning we make with language as well as other objects. events, and actions. Social semiotics emphasizes the social, cultural, historic, and political contexts that shape that meaning. A social semiotic approach to education can help teachers and teacher educators to deconstruct the reproduction of class, politicize the ideology of colonialism, and overcome the inequities they engender. By providing a way to challenge selectively reproduced cultural politics, social semiotics provides a way to reconstruct and democratize schools and society.

Fuzzy Thinking: A Borrowed Paradigm For Crisper Lawyering, David F. Chavkin

Clinical Law Review

The answer to Ed's question is that by applying bivalent or crisp thinking Catherine has reached an apparently unresolvable paradox. By contrast, by applying fuzzy thinking, Ed has found a real-life answer to this longstanding problem. Fuzzy logic thereby has bridged a gap and permitted a waltz that would not otherwise have been possible. On that basis alone, fuzzy logic deserves a careful examination. This article analyzes whether the "fuzzy thinking" paradigm has potential benefits for our clinical teaching and for improved performance of lawyering tasks by ourselves and by our students. It reviews the development of "fuzzy thinking" and …

Law And Phrenology, Pierre Schlag

Publications

As the intellectual credentials of American law become increasingly dubious, the question arises: how has this discipline been intellectually organized to sustain belief among its academic practitioners? This Commentary explores the nineteenth-century pseudo-science of phrenology as a way of gaining insight into the intellectual organization of American law. Although there are, obviously, significant differences, the parallels are at once striking and edifying. Both phrenology and law emerged as disciplinary knowledges through attempts to cast them in the form of sciences. In both cases, the "sciences" were aesthetically organized around a fundamental ontology of reifications and animisms -- "faculties" in the …

Azo Dyes Based On 1,10-Phenanthroline, Minchong Mao

Masters Theses

A series of new phenanthroline based azo-dye ligands, produced by diazotizing 5-amino-1,10-phenanthroline (5-NH₂-phen) and then coupling this intermediate to a variety of coupling components, has been synthesized and characterized. The coupling components used were β-naphthol, phenol, and 2,6-dimethylphenol, and the three dye ligands were named phen-azo-β-naphthol, phen-azo-p-phenol, and phen-azo-2,6-dimethylphenol, respectively. ¹H-NMR and IR spectra showed that the dyes exist primarily in the azo form in DMSO solution and as solids. UV-Vis spectra (in MeOH) showed intense (ε ≅ 10⁴ M^-1cm^-1) absorptions ranging from 380 nm to 500 nm for these ligands.

Hartogs' Phenomenon For Polyregular Functions And Projective Dimension Of Related Modules Over A Polynomial Ring, W. W. Adams, P. Loustaunau, V. P. Palamadov, Daniele C. Struppa

Mathematics, Physics, and Computer Science Faculty Articles and Research

In this paper we prove that the projective dimension of Mn = R^4/(An) is 2n -1, where R is the ring of polynomials in 4n variables with complex coefficients and (An) is the module generated by the columns of a 4x4n matrix which arises as the Fourier transform of the matrix of differential operators associated with the regularity condition for a function of n quaternionic variables. As a corollary we show that the sheaf R of regular functions has flabby dimension 2n -1, and we prove a cohomology vanishing theorem for open sets in the space Hn of quaternions. We …

Science And Christianity: The Positive Attitude, C. Gordon Winder

Journal of Hindu-Christian Studies

The Judeo-Christian Scriptures have been considered by literalists as true in every aspect, including references to the sciences. Scripture states that earth has four corners suggesting that the earth is flat. The sun rises in the morning suggesting that the sun goes around the earth, and earth with humankind is at the centre of the universe. The six days in the Genesis account along with the genealogical chronologies were used by Irish Bishop James Ussher (1581-1652) to calculate that the earth's origin was in 4004 B.C. The Genesis account relates that the origin of humankind, and all the plants and …

Vendanta And Modern Science: Some Demarcation Criteria And Commonalities, Varadaraja V. Raman

Journal of Hindu-Christian Studies

In the past centuries, Western scholars who studied the complexities of Indian thought had at least two motivations. First, there was a need to understand the alien mind-set which they were eager to ameloriate (convert), for they worked on the conviction that they were bringing truth, light, and salvation to a misguided lot. They felt that it was their evangelical responsibility to redeem lost souls. Some of them, whether overtly or subtly, wanted to give moral ammunition to the colonial governments which were summarily imposing Western values and worldview on the subject peoples.

About Some Normal Subgroups Of Hecke Groups, İsmail Naci Cangül

Turkish Journal of Mathematics

In this work we study the suucture of some special normal subgroups of Hecke groups. Particwarly those of genus O and 1 are studied by means of the regwar map theory which has been a growing subject in recent years. As a nice application, we calcwate the total number of genus 1 normal subgroups for a given index.

Locally Topological Groupoids, Osman Mucuk

Turkish Journal of Mathematics

The notion of Iocally topological groupoid was introduced by Aof and Brown in [2]. On the other hand in [6] by Mackenzie a topological groupoid MG, called monodromy groupoid, is constructed. In this paper we prove that this groupoid MG gives a Iocally topological groupoid.

The Spectra And Fine Spectra For P-Cesáro Operators, Cafer Coşkun

In [6], Rhaly computed the spectrum of p-Cesaro operator on the Hilbert space l_2 = {x = (x_k): \Sigma_k IX_kl^2 < infinite}. In the present paper, we study the spectrum and fine spectrum for p-Cesáro operators acting on C_o, the space of null sequences.

Painlevé Analysis And Infinite Lie Symmetries Of The Complex Modified Korteweg-De Vries-Ii Equation, Abulgassim Ali Muhammad, Mehmet Can

Turkish Journal of Mathematics

The Painleve analysis developed by Weiss et al. [9] for nonlinear partial differential equations is applied to the CMKdV-II equation. It has been shown that this equation passes the Painleve test. By specializing the arbitrary functions that appear in the phi series expansions found in the test, one obtains a system of partial differential equations for the formally arbitrary data. For specific systems, and conjectured in general, these equations are integrable. The form of the resulting reduction enables the identification of integrable reductions of the original systems. Assuming u_i = \upsilon_i = 0, i >= 2 we obtain conditions to …
