Molecular Interaction Between Perthiolated [Beta]-Cyclodextrin (Cd) And The Guests Molecules Adamantaneacetic Acid (Ad) And Ferroceneacetic Acid (Fc); And The Effect Of The Interaction On The Electron Transition Of Cd Anchored Particles, Ming Ning

Dissertations, Master's Theses and Master's Reports - Open

The molecular interactions between the host molecule, perthiolated beta-cyclodextrin (CD), and the guest molecules, adamantaneacetic acid (AD) and ferroceneacetic acid (FC), have been inestigated theoretically in both the gas and aqueous phases. The major computations have been carried out at the theoretical levels, RHF/6-31G and B3LYP/6- 31G. MP2 electronic energies were also computed based at the geometries optimized by both the RHF and B3LYP methods in the gas phase to establish a better estimate of the correlation effect.

The solvent phase computations were completed at the RHF/6-31G and B3LYP/6-31G levels using the PCM model. The most stable structures optimized in …

Estimation Of The Degree Of Polarization Through Computational Sensing, Wei Wang

Dissertations, Master's Theses and Master's Reports - Open

The degree of polarization of a refected field from active laser illumination can be used for object identifcation and classifcation. The goal of this study is to investigate methods for estimating the degree of polarization for refected fields with active laser illumination, which involves the measurement and processing of two orthogonal field components (complex amplitudes), two orthogonal intensity components, and the total field intensity. We propose to replace interferometric optical apparatuses with a computational approach for estimating the degree of polarization from two orthogonal intensity data and total intensity data. Cramer-Rao bounds for each of the three sensing modalities with …

Assessment Of A High School Geological Field Course, Eric Morgan Ruckert

Dissertations, Master's Theses and Master's Reports - Open

Fieldwork is supportive of students’ natural inquiry abilities. Educational research findings suggest that instructors can foster the growth of thinking skills and promote science literacy by incorporating active learning strategies (McConnel et al, 2003). Huntoon (2001) states that there is a need to determine optimal learning strategies and to document the procedure of assessing those optimal geoscience curricula. This study seeks to determine if Earth Space II, a high school geological field course, can increase students’ knowledge of selected educational objectives. This research also seeks to measure any impact Earth Space II has on students’ attitude towards science.

Integrated Water Resources Management And Modeling At Multiple Spatial Scales In Jordan, David E. Rosenberg

Civil and Environmental Engineering Faculty Publications

Water shortages from intermittent public supplies are a major and expanding problem in the Hashemite Kingdom of Jordan. Yet individual users, utility managers, and government officials can improve access or cope with shortages in many ways. New supplies, more efficient use of existing resources, long-term investments to expand infrastructure and reduce leakage, and short-term measures to flexibly transfer, ration, or curtail some uses represent several different approaches for management. This paper reviews three separate systems analysis that use stochastic optimization with recourse. Analysis for individual residential users, the water utility serving 2.2 million residents in the capital Amman, and the …

Shades Of Grey: A Critical Review Of Grey-Number Optimization, David E. Rosenberg

Civil and Environmental Engineering Faculty Publications

A grey number is an uncertain number with fixed lower and upper bounds but unknown distribution. Grey numbers find use in optimization to systematically and proactively incorporate uncertainties expressed as intervals plus communicate resulting stable, feasible ranges for the objective function and decision variables. This article critically reviews their use in linear and stochastic programs with recourse. It summarizes grey model formulation and solution algorithms. It advances multiple counter-examples that yield risk-prone grey solutions that perform worse than a worst-case analysis and do not span the stable feasible range of the decision space. The article suggests reasons for the poor …

Modeling Integrated Decisions For A Municipal Water System With Recourse And Uncertainties: Amman, Jordan, David E. Rosenberg, Jay Lund

Civil and Environmental Engineering Faculty Publications

Stochastic mixed-integer optimization is used to identify a portfolio of long- and short-term supply and conservation actions for a municipal water system to cost-effectively accommodate a distribution of water shortages. Alternative robust, grey-number, and best/worst case formulations systematically explore implications of uncertainties in action costs, life spans, water volumes gained or saved, shortage levels, and shortage probabilities. A detailed example for Amman, Jordan considers 23 potential actions. Results show: (1) remarkable consistency occurs across the different modeling approaches. (2) Conserving water—reducing leakage and targeting select customers to install water efficient appliances—plays an important and growing role over time. (3) A …

Flood Susceptible Mapping And Risk Area Delineation Using Logistic Regression, Gis And Remote Sensing

Journal of Spatial Hydrology

Recently, in the year 2006, 2007 and 2008 heavy monsoons rainfall have triggered floods along Malaysia's east coast as well as in different parts of the country. The hardest hit areas are along the east coast of peninsular Malaysia in the states of Kelantan, Terengganu and Pahang. The flood cost nearly millions of dollars of property and many lives. Foods are considered to be one of the weather-related natural disasters. Many methods exist to provide qualitative estimations of the risk level of flood susceptibility mapping within a watershed. This paper presents construction of a flood susceptible map for presumptive flood …

A Formal Concept Analysis Approach To Association Rule Mining: The Quicl Algorithms, David T. Smith

CCAC Theses and Dissertations

Association rule mining (ARM) is the task of identifying meaningful implication rules exhibited in a data set. Most research has focused on extracting frequent item (FI) sets and thus fallen short of the overall ARM objective. The FI miners fail to identify the upper covers that are needed to generate a set of association rules whose size can be exploited by an end user. An alternative to FI mining can be found in formal concept analysis (FCA), a branch of applied mathematics. FCA derives a concept lattice whose concepts identify closed FI sets and connections identify the upper covers. However, …

On The Approximability Of Dodgson And Young Elections, Ioannis Caragiannis, Jason Covey, Michal Feldman, Christopher Homan, Christos Kaklamanis, Nikos Karanikolas, Ariel D. Procaccia, Jeffrey S. Rosenschein

Articles

The voting rules proposed by Dodgson and Young are both designed to nd the alternative closest to being a Condorcet winner, according to two di erent notions of proximity; the score of a given alternative is known to be hard to compute under either rule. In this paper, we put forward two algorithms for ap- proximating the Dodgson score: an LP-based randomized rounding algorithm and a deterministic greedy algorithm, both of which yield an O(logm) approximation ratio, where m is the number of alternatives; we observe that this result is asymptotically optimal, and further prove that our greedy algorithm is …

Identifying Layout Classes For Mathematical Symbols Using Layout Context, Ling Ouyang, Richard Zanibbi

Articles

We describe a symbol classification technique for identifying the expected locations of neighboring symbols in mathematical expressions. We use the seven symbol layout classes of the DRACULAE math notation parser (Zanibbi, Blostein, and Cordy, 2002) to represent expected locations for neighboring symbols: Ascender, Descender, Centered, Open Bracket, Non-Script, Variable Range (e.g. integrals) and Square Root. A new feature based on shape contexts (Belongie et al., 2002) named layout context is used to describe the arrangement of neighboring symbol bounding boxes relative to a reference symbol, and the nearest neighbor rule is used for classification. 1917 mathematical symbols from the University …

Bayesian Computation Of The Intrinsic Structure Of Factor Analytic Models, Ernest Fokoue

Articles

The study of factor analytic models often has to address two important issues: (a) the determination of the “optimum” number of factors and (b) the derivation of a unique simple structure whose interpretation is easy and straightforward. The classical approach deals with these two tasks separately, and sometimes resorts to ad-hoc methods. This paper proposes a Bayesian approach to these two important issues, and adapts ideas from stochastic geometry and Bayesian finite mixture modelling to construct an ergodic Markov chain having the posterior distribution of the complete collection of parameters (including the number of factors) as its equilibrium distribution. The …

Insulation Condition Assessment Of Power Transformers Using Accelerated Ageing Tests, Mohammad Mirzaie, Ahmad Gholami, Hamid Reza Tayebi

Turkish Journal of Electrical Engineering and Computer Sciences

Thermal stress due to losses and environment temperature causes degradation to paper/oil insulation systems in transformers, even at operating temperature. Experience indicates that thermal ageing of oil and paper in power transformers leads to the change of some insulation characteristics. In this paper, insulating papers immersed in oil have been acceleratory aged at 140, 150, and 160 °C under laboratory conditions. Some of the oil properties, such as water content, breakdown voltage, acidity, together with the aged insulating paper properties such as electric strength, dielectric dissipation factor and tensile strength were measured and analyzed. Also, insulation system conditions under thermal …

Softcomputing Identification Techniques Of Asynchronous Machine Parameters: Evolutionary Strategy And Chemotaxis Algorithm, Nouri Benaïdja

Turkish Journal of Electrical Engineering and Computer Sciences

Softcomputing techniques are receiving attention as optimisation techniques for many industrial applications. Although these techniques eliminate the need for derivatives computation, they require much work to adjust their parameters at the stage of research and development. Issues such as speed, stability, and parameters convergence remain much to be investigated. This paper discusses the application of the method of reference model to determine parameters of asynchronous machines using two optimisation techniques. Softcomputing techniques used in this paper are evolutionary strategy and the chemotaxis algorithm. Identification results using the two techniques are presented and compared with respect to the conventional simplex technique …

Pca Based Protection Algorithm For Transformer Internal Faults, Erdal Kiliç, Okan Özgönenel, Ömer Usta, Dave Thomas

Turkish Journal of Electrical Engineering and Computer Sciences

In this paper a new protection scheme is introduced to detect and identify transformer winding faults. The new approach is based on artificial neural networks (ANNs) using radial basis functions (RBFs) and the principal component analysis (PCA). The nonlinear system's input and output data is manipulated without considering any model of the system. This approach is used to detect and identify internal short circuit faults of a three phase custom built transformer. The suggested technique is also able to distinguish between the fault and magnetizing inrush current. The test studies carried out shows that the proposed method leads to satisfactory …

Weak Penetration And Radiation Through Apertures In Conducting Bodies Of Revolution, Korkut Yeği̇n

Turkish Journal of Electrical Engineering and Computer Sciences

The simplest way to solve for penetration through small apertures in conducting surfaces is to treat the body as a scatterer and determine the interior field as the sum of the incident field and the scattered field contributed by the current induced on the surface of the body. However, it is well known that, if the aperture is very small or if the penetrated field is very weak this method yields very inaccurate results, which, in turn, prohibits proper design of electronic systems, especially for electromagnetic compatibility and interference. Previously, alternative integral equations formulations were proposed to remedy this problem …

Development Of A Magnetic Field Model And Insertion~Into A Commercial Electromagnetic Simulator, Priscila Fernandez Lopez, Christian Arcambal, Yolanda Vives Gilabert, Abhishek Ramanujan, David Baudry, Anne Louis, Belahcene Mazari

Turkish Journal of Electrical Engineering and Computer Sciences

To take into account~certain ElectroMagnetic Compatibility (EMC) aspects~and especially to evaluate the magnetic fields radiated by electronic components, different radiated emission models have been created. Within IRSEEM, a magnetic field model based on equivalent sources (electric dipoles) placed on a plane has been developed. Thus, this paper presents the modelling procedure that requires~magnetic near-field measurements and matrix inversion methods. Concerning the measurements of the field radiated by the component under test,~a near-field test bench with a loop antenna is used to~quantify the tangential components of the magnetic field in amplitude and phase. Then, these data are used as input to …

Cognition, Law, Stories, Stephen M. Mcjohn, Lorie Graham

Suffolk University Law School Faculty Works

This essay reviews Steven Pinker, The Stuff of Thought (Penguin 2007), which offers insights from cognitive science just where it overlaps the most with law - how we use basic cognitive categories like intent, space, time, events and causation. The Stuff of Thought might offer insights into a broad range of issues in legal theory. Legal theory could make more use of such cognitive science concepts as chunking, recursion, and the primary qualities of an object. Other topics likewise resonate in thinking about the law: The book suggests that metaphor is an important cognitive tool, but less constraining than might …

The Relationship between Positive Behavior Supports, Student Achievement, Severe Problem Behavior, and Administrative Stress

Chair: Dr. John Matt

Due to the pressures and expectations for current and future principals to create safe and welcoming schools with high student achievement, a better of understanding of the relationship between Positive Behavior Supports (PBS), student achievement, severe problem behavior, and administrative stress was needed. This study investigated the relationship between these four factors, as measured through the Effective Behavior Supports Survey (Sugai, Horner, & Todd, 2003), Adequate Yearly Progress (AYP) (OPI, 2008), suspension/expulsion rates, the …

Beyond Wilderness: Wildness As A Guiding Ideal, Christopher James Dunn

Graduate Student Theses, Dissertations, & Professional Papers

This thesis is largely a response to William Cronon’s essay “The Trouble with Wilderness or Getting Back to the Wrong Nature,” found in The Great New Wilderness Debate. Cronon is himself responding to many things, in large part to Bill McKibben’s The End of Nature and also to the wilderness vision typified by Dave Foreman; thus this thesis is also a response to McKibben and in many respects a defense of Foreman-like thought. Besides Cronon, I consider a wide variety of sources, taking from them in order to build a case for, and to explicate, wildness as a guiding ideal. …

Integration Of Higher-Order Physics In The Community Ice Sheet Model: Scientific And Software Concerns, Timothy Joseph Bocek

Graduate Student Theses, Dissertations, & Professional Papers

The Community Ice Sheet Model (CISM) is a next-generation land ice model that is designed to answer important questions regarding the response of Earth’s land ice to climate forcing. The program extends Glimmer, an ice sheet model based on the shallow ice approximation. This thesis concerns a project to ready CISM for these questions by integrating an ice velocity diagnostic based on a first-order approximation of the Navier-Stokes equations. I present in detail the derivation of the first-order momentum balance equations for both the interior of an ice sheet and a variety of boundary conditions. I discuss the numerical techniques …

Graduate Student Theses, Dissertations, & Professional Papers

The purpose of this research was to attempt to identify the population affinity of three crania (UMFC 103, 104, and 120), housed at the University of Montana Physical Anthropology Lab, using multivariate statistical analyses. A database collected by Dr. Hanihara and another collected by researchers at the University of Michigan were used for comparative purposes. Multiple populations from both databases were chosen so as to be representative of various Asian, African, Indian, and Native American populations. Two variations of each of the databases were used in the following statistical analyses: principal components analysis and discriminant function analysis. It was shown …

Mormon Cinema On The Web, Randy Astle

BYU Studies

Mormon cinema on the Internet is a moving target. Because change in this medium occurs so rapidly, the information presented in this review will necessarily become dated in a few months and much more so in the years to come. What I hope to provide, therefore, is a snapshot of online resources related to LDS or Mormon cinema near the beginning of their evolution. I believe that the Internet will become the next great force in both Mormon cinema and world cinema in general, if it has not already done so. Hence, while the current article may prove useful for …

The International Life Of A Swiss Hotelkeeper, Marianne Burkhard

Swiss American Historical Society Review

Among the papers of Ferdinand Sperl there is a

small black book in which he chronicled the stages of

his life from his childhood to the 1960s. This

chronicle is very interesting as it shows first, how the

son of a hotelier was thoroughly prepared for

following in his family's footsteps as a fourth

generation hotelier, and second, how his arrival in the

United States in 1939 and the Second World War led

him to an unexpected career in military intelligence

after which he returned to his career as hotelier.

In particular, this article details the algorithms and the software design of Radiotherapy optimAl Design (RAD).

The Impact Of Traditional And Alternative University Teacher Preparation Program Options On Secondary Teacher Candidates’ Knowledge, Skills, Dispositions, And Employment, Rebecca B. Schnabel

Student Work

The preparation of secondary teacher candidates through traditional (n = 13) or alternative (n = 15) options did not statistically significantly impact knowledge, skills or dispositions. Results for content knowledge, as measured at entrance to the program based on the Pre-Professional Skills Test, indicate that candidates who entered the traditional secondary teacher preparation program begin their studies with measured content knowledge in reading, writing, and mathematics that was congruent with the content knowledge of post-baccalaureate candidates who entered the alternative secondary teacher preparation program. Furthermore, content knowledge, based on cumulative grade point averages calculated upon completion of all …

Common Raven Nests In North Dakota After 100-Year Hiatus, Melvin P. Nenneman, Todd A. Grant, Ron E. Martin

The Prairie Naturalist

Our observations represent the first documented nesting by the common raven in North Dakota since the late 1800's. Houston (1977) suggested that the expansion of the American crow onto the Canadian prairies was limited by the scarcity of trees for nest sites, which also might have limited the extent of the common raven. Aspen woodland has increased substantially in and around J. Clark Salyer National Wildlife Refuge since European settlement, due primarily to fire suppression and extirpation of large herbivores (Grant and Murphy 2005). Thus, plausibly these increases in woodland habitat might be providing nest sites necessary for the common …
