Reinforcement Learning-Based Control Design For Load Frequency Control, Sara Eftekharnejad

Graduate Theses, Dissertations, and Problem Reports (ETD)

Energy balance in electric power systems is continuously disrupted by constant demand changes due to customers' switching in and out, or loss of generating units. Load frequency control (LFC) is very essential for interconnected power systems in order to maintain the energy balance which is assessed through the Area Control Error, a signal that is made up of deviations from their nominal values of the system frequency and power area interchanges. Each balancing authority is responsible for its own energy balance in accordance with North American Electric Reliability Corporation (NERC) standards.;This thesis presents a novel approach to the LFC problem. …

Environmental Variation, Stochastic Extinction, And Competitive Coexistence, Peter B. Adler, John M. Drake

Wildland Resources Faculty Publications

Understanding how environmental fluctuations affect population persistence is essential for predicting the ecological impacts of expected future increases in climate variability. However, two bodies of theory make opposite predictions about the effect of environmental variation on persistence. Single‐species theory, common in conservation biology and population viability analyses, suggests that environmental variation increases the risk of stochastic extinction. By contrast, coexistence theory has shown that environmental variation can buffer inferior competitors against competitive exclusion through a storage effect. We reconcile these two perspectives by showing that in the presence of demographic stochasticity, environmental variation can increase the chance of extinction while …

Misapplying Equity Theories: Dress Codes At Work, Jennifer L. Levi

Faculty Scholarship

This Article provides a new perspective on Title VII caselaw concerning employer-mandated, sex-specific dress codes. With few exceptions, courts have held that employer dress codes do not constitute sex discrimination even when they expressly differentiate based solely on an employee's sex. In other contexts, courts readily acknowledge that facially sex-based practices and policies are presumptively unlawful under Title VII. When it comes to dress codes, however, nearly the opposite is true. Courts generally presume a sex-based dress code to be permissible, and the burden falls heavily on the employee to show, beyond the mere fact of differential treatment, some additional …

Adult Complicity In The Dis-Education Of The Black Male High School Athlete & Societal Failures To Remedy His Plight, Kimberly Jade Norwood

Scholarship@WashULaw

This Article focuses on the educational hurdles facing many Black male student athletes in urban high schools. Academic rigor is rarely expected of these students. They are part of an active form of dis-education. By dis-education, I mean the active failure to educate. Our learning institutions have become so accustomed to excusing these students from academic rigor that doing so simply does not spark a sense of outrage or any notion that we are doing something wrong when it comes to our expectations of these students. No one really questions them when they do poorly on class work and tests. …

Measuring Deviations From Expected Voting Patterns On Collegial Courts, Stefanie A. Lindquist, Paul H. Edelman, David E. Klein

Scholarship@WashULaw

Even where idiosyncratic factors such as ideology play large and consistent roles in judges' decision-making, there are always cases where the patterns of judges' votes confound our expectations. In some ways, these are among the most interesting cases for scholars, raising important questions about judicial behavior and institutions. In the first part of this paper, we introduce a quantitative measure of deviations from expected voting patterns intended to allow scholars to systematically study unexpected votes and the questions they raise. In the second part, we illustrate the use of this new measure by developing a preliminary model to predict departures …

Seasonal Adaptation Of Vegetation Color In Satellite Images, Srinivas Jakkula, Vamsi K.R. Mantena, Ramu Pedada, Yuzhong Shen, Jiang Li, Hamid R. Arabnia (Ed.)

Electrical & Computer Engineering Faculty Publications

Remote sensing techniques like NDVI (Normal Difference vegetative Index) when applied to phenological variations in aerial images, ascertained the seasonal rise and decline of photosynthetic activity in different seasons, resulting in different color tones of vegetation. The rise and fall of NDVI values decide the biological response, either the green up or brown down [1]. Vegetation in green up period appears with more vegetative vigor and during brown down period it has a dry appearance. This paper proposes a novel method that identifies vegetative patterns in satellite images and then alters vegetation color to simulate seasonal changes based on training …

Catholic Social Teaching And Health Care For All, Patrick T. Mccormick M.S.

Verbum Incarnatum: An Academic Journal of Social Justice

Over 47 million Americans find themselves without health insurance in the richest and most Christian nation in the world. Catholic Social Teaching views this situation as an unjust violation of a basic human right to medical care, arguing that all persons have the right to those goods and services necessary for the proper development of life. In making this claim, Catholic Social Teaching advances three biblical principles: (1) that all persons are sacred and social, (2) that God hears the cries of the poor, and (3) that believers are directed to make a preferential option for the poor. In addition, …

Dominance Of Virtual Delbrück Scattering For The Photon Emission By Nuclei In Relativistic Electron-Nucleus And Nucleus-Nucleus Collisions, Ilya F. Ginzburg, Ulrich D. Jentschura, Valery G. Serbo

Physics Faculty Research & Creative Works

We consider the contribution of virtual Delbrück scattering to the photon emission by nuclei in the collision of two ultra-relativistic nuclei Z₁ Z₂ → Z₁ Z₂ γ and electron-nucleus collisions e Z → e Z γ, in the photon energy range m ≪ E_γ ≪ m γ, where m is the electron mass and γ is the Lorentz factor of the colliding nucleus. The discussed process has no infrared divergence. The total cross section is 50 barn for the Pb-Pb collisions at the LHC collider. The spectral distribution obtained is considerably larger than for ordinary …

The Biot-Savart Law: From Infinitesimal To Infinite, Jeffrey A. Phillips, Jeff Sanny

Physics Faculty Works

In this paper, we discuss a simple apparatus and accompanying class activity that we have developed to illustrate the Biot-Savart law. Since students in introductory electricity and magnetism courses often find this law a mathematical mystery, we feel that a simple experiment such as this will provide the students a better understanding of the concepts introduced. By collecting data from several finite segment lengths, students are able to infer the 1/r² distance dependence of the magnetic field for infinitesimal segments and the 1/r dependence for infinite wires.

Measuring The Elf Response Of An Acupuncture Meridian Compared To A Control Channel, Keith Spaulding

Master's Theses and Capstones

Acupuncture meridians are said to possess unique electrical characteristics; a characteristic of interest when analyzing systems is frequency response. The Extremely Low Frequency (ELF) response of the Large Intestine (LI) meridian was found by applying a Gaussian pulse signal to LI4 and detecting the signal at LI11; a Fast Fourier Transform (FFT) analysis is performed on this signal with a Power Spectral Density (PSD) measuring total power in the 2 -- 100 Hz region. This total power is compared to the total power measurement at a control point by applying the same Gaussian pulse on a control channel; this protocol …

Carbonyl Sulfide (Ocs): Large Scale Distributions Over North America During Intex-Na And Relationship To Co2, Lambert Doezema

Chemistry and Biochemistry Faculty Works

An extensive set of carbonyl sulfide (OCS) observations were made as part of the NASA Intercontinental Chemical Transport Experiment-North America (INTEX-NA) study, flown from 1 July to 14 August 2004 mostly over the eastern United States and Canada. These data show that summertime OCS mixing ratios at low altitude were dominated by surface drawdown and were highly correlated with CO2. Although local plumes were observed on some low-altitude flight legs, anthropogenic OCS sources were small compared to this sink. These INTEX-NA observations were in marked contrast to the early springtime 2001 Transport and Chemical Evolution over the Pacific experiment, which …

Should I Stay Or Should I Go? Eukaryotic Translation Initiation Factors 1 And 1a Control Start Codon Recognition, Sarah F. Mitchell

Chemistry and Biochemistry Faculty Works

Start codon selection is a key step in translation initiation as it sets the reading frame for decoding. Two eukaryotic initiation factors, eIF1 and eIF1A, are key actors in this process. Recent work has elucidated many details of the mechanisms these factors use to control start site selection. eIF1 prevents the irreversible GTP hydrolysis that commits the ribosome to initiation at a particular codon. eIF1A both promotes and inhibits commitment through the competing influences of its two unstructured termini. Both factors perform their tasks through a variety of interactions with other components of the initiation machinery, in many cases mediated …

Weight Systems For Milnor Invariants, Blake Mellor

Mathematics, Statistics and Data Science Faculty Works

We use Polyak's skein relation to give a new proof that Milnor's string link homotopy invariants are finite type invariants, and to develop a recursive relation for their associated weight systems. We show that the obstruction to the triviality of these weight systems is the presence of a certain kind of spanning tree in the intersection graph of a chord diagram.

Musical Actions Of Dihedral Groups, Alissa S. Crans, Thomas M. Fiore, Ramon Satyendra

Mathematics, Statistics and Data Science Faculty Works

The sequence of pitches which form a musical melody can be transposed or inverted. Since the 1970s, music theorists have modeled musical transposition and inversion in terms of an action of the dihedral group of order 24. More recently music theorists have found an intriguing second way that the dihedral group of order 24 acts on the set of major and minor chords. We illustrate both geometrically and algebraically how these two actions are {\it dual}. Both actions and their duality have been used to analyze works of music as diverse as Hindemith and the Beatles.

Value Monoids Of Zero-Dimensional Valuations Of Rank 1, Edward Mosteig

Mathematics, Statistics and Data Science Faculty Works

Classically, Grobner bases are computed by first prescribing a set monomial order. Moss Sweedler suggested an alternative and developed a framework to perform such computations by using valuation rings in place of monomial orders. We build on these ideas by providing a class of valuations on k(x, y) that are suitable for this framework. For these valuations, we compute ν(k[x, y] ∗ ) and use this to perform computations concerning ideals in the polynomial ring k[x, y]. Interestingly, for these valuations, some ideals have a finite Grobner basis with respect to the valuation that is not …

Cohomology Of Categorical Self-Distributivity, J. Scott Carter, Alissa S. Crans, Mohamed Elhamdadi, Masahico Saito

Mathematics, Statistics and Data Science Faculty Works

We define self-distributive structures in the categories of coalgebras and cocommutative coalgebras. We obtain examples from vector spaces whose bases are the elements of finite quandles, the direct sum of a Lie algebra with its ground field, and Hopf algebras. The self-distributive operations of these structures provide solutions of the Yang–Baxter equation, and, conversely, solutions of the Yang–Baxter equation can be used to construct self-distributive operations in certain categories. Moreover, we present a cohomology theory that encompasses both Lie algebra and quandle cohomologies, is analogous to Hochschild cohomology, and can be used to study deformations of these self-distributive structures. All …

Four Varieties Of Character-Based Virtue Epistemology, Jason Baehr

Philosophy Faculty Works

The terrain of character-based or “responsibilist” virtue epistemology has evolved dramatically over the last decade — so much so that it is far from clear what, if anything, unifies the various views put forth in this area. In an attempt to bring some clarity to the overall thrust and structure of this movement, I develop a fourfold classification of character-based virtue epistemologies. I also offer a qualified assessment of each approach, defending a certain account of the probable future of this burgeoning subfield.

Quasiclassical Description Of Bremsstrahlung Accompanying Α Decay Including Quadrupole Radiation, Ulrich D. Jentschura, A. I. Milstein, Ivan S. Terekhov, H. Boie, Heiko Scheit, Dirk Schwalm

Physics Faculty Research & Creative Works

We present a quasiclassical theory of α decay accompanied by bremsstrahlung with a special emphasis on the case of ²¹⁰Po, with the aim of finding a unified description that incorporates both the radiation during the tunneling through the Coulomb wall and the finite energy E_γ of the radiated photon up to E_γ~Q_α | √/η, where Q_α is the α-decay Q-value and η is the Sommerfeld parameter. The corrections with respect to previous quasiclassical investigations are found to be substantial, and excellent agreement with a full quantum mechanical treatment is achieved. Furthermore, we find that …

The Introduction Of A 'Learning In The Workplace' Component For An Undergraduate It Program And Its Impact On Professional Accreditation, Grace Tan, Anne Venables

EDU-COM International Conference

A new learning in the workplace and community policy (LiWC) at Victoria University has been introduced to ensure that graduates are job and career ready. The policy mandates that all programs incorporate at least a 25% workplace contextual learning component by 2010. For the IT undergraduate program, compliance with this policy poses a number of significant challenges, not least of which is the meeting of professional accreditation criteria. Acquiring a recognized professional body accreditation, like that of the Australian Computer Society (ACS), is pivotal for all IT Australian programs, in that, it is a vital quality assurance measure and it …
