Towards Tractable Local Closed World Reasoning For The Semantic Web, Matthias Knorr, Jose Julio Alferes, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Recently, the logics of minimal knowledge and negation as failure MKNF [12] was used to introduce hybrid MKNF knowledge bases [14], a powerful formalism for combining open and closed world reasoning for the Semantic Web. We present an extension based on a new three-valued framework including an alternating fixpoint, the well-founded MKNF model. This approach, the well-founded MKNF semantics, derives its name from the very close relation to the corresponding semantics known from logic programming. We show that the well-founded MKNF model is the least model among all (three-valued) MKNF models, thus soundly approximating also the two-valued MKNF models from …

Neural-Network-Based Intelligent Control For Improving Dynamic Performance Of Facts Devices, Wei Qiao, Ronald G. Harley, Ganesh K. Venayagamoorthy

Electrical and Computer Engineering Faculty Research & Creative Works

Flexible ac transmission system (FACTS) devices are widely recognized as powerful controllers to improve the dynamic performance and stability of power systems. the standard FACTS controllers are linear controllers designed around a specific operating point from a linearized system model with fixed parameters. However, at other operating points their performance degrades. Neural-network-Based nonlinear intelligent control offers an attractive approach to overcome the drawbacks of the linear controllers. This paper presents two different neural-network-Based intelligent control architectures, i.e., indirect adaptive NeuroControl and adaptive critic design based optimal NeuroControl, for designing the external control of an SSSC FACTS device. Simulation studies are …

Foraging Behavior And Habitat Use By The Carolina Chickadee (Poecile Carolinensis) In West-Central Indiana, Ihan Chen

All-Inclusive List of Electronic Theses and Dissertations

I studied the effect of environmental conditions on the foraging behavior of Carolina chickadees (Poecile carolinensis) in Kiewig woods, property of Indiana State University, in West Terre Haute in west-central Indiana. My study method uses Optimal Foraging Theory (Brown 1988) to measure the giving up density (GUD) of Chickadees under different environmental conditions ( different resource abundances, different habitat types, different resource types and different seasons). For my experiment, I set up 24 feeding stations in three kinds of habitats ( open area, secondary growth woods and mature woods) within 4 sites and paired trays in each habitat X site. …

Reinterpreting The Pollen Data From Dos Cabezas, Karl J. Reinhard, Vaughn M. Bryant, Sheila D. Vinton

School of Natural Resources: Faculty Publications

The published pollen analysis of the Dos Cabezas giants, Geyer et al. (2003), lists variety of purported dietary pollen types. The paper also hypothesises that the giants were poisoned with plant toxins. We have severe reservations about the pollen evidence of diet and poisoning. We suggest that the analysts made several errors in their interpretation. Firstly, some of the discovered pollen types are not prehistoric endemics to the Dos Cabezas region of coastal Peru. These include the pollen of fava beans (cultivated in the Old World), and specified species of agave and sage. We believe that some or all of …

Statistics In The Jury Box: How Jurors Respond To Mitochondrial Dna Match Probabilities, David H. Kaye, Valerie P. Hans, B. Michael Dann, Erin J. Farley, Stephanie Albertson

Cornell Law Faculty Publications

This article describes parts of an unusually realistic experiment on the comprehension of expert testimony on mitochondrial DNA (mtDNA) sequencing in a criminal trial for robbery. Specifically, we examine how jurors who responded to summonses for jury duty evaluated portions of videotaped testimony involving probabilities and statistics. Although some jurors showed susceptibility to classic fallacies in interpreting conditional probabilities, the jurors as a whole were not overwhelmed by a 99.98% exclusion probability that the prosecution presented. Cognitive errors favoring the defense were more prevalent than ones favoring the prosecution. These findings lend scant support to the legal argument that mtDNA …

Decomposition-Based Recovery Of Absorbers In Turbid Media, S D. Campbell, I L. Goodin, S D. Grobe, Qichang Su, Rainer Grobe

Faculty publications – Physics

We suggest that the concept of the point-spread function traditionally used to predict the blurred image pattern of various light sources embedded inside turbid media can be generalized under certain conditions to predict also the presence and location of spatially localized absorbing inhomogeneities based on shadow point-spread functions associated with each localized absorber in the medium. The combined image obtained from several absorbers can then be decomposed approximately into the arithmetic sums of these individual shadow point-spread functions with suitable weights that can be obtained from multiple-regression analysis. This technique permits the reconstruction of the location of absorbers.

The Implementation Of A Repository For Data Reporting And Analysis, Christopher Haufschild

Masters Theses & Doctoral Dissertations

Data-driven decision making has become increasingly important within the context of the public school system. The benefits of having fast and accurate data available to both teachers and administrators are being touted across the country and the world. There is a need within Moorhead Area Public Schools for a system to facilitate this in a secure and user-friendly manner in order to provide necessary data to users without sacrificing instructional time for students. Within this system it is important to provide only the data that is necessary for decision making in order to keep student privacy at the highest level …

Study Of Multiple Impacts Of A Rigid Body With A Flat Surface, Florin Vasile Badiu

Mathematics Dissertations - Archive

Both analytical and numerical results are presented for two rigid body problems: a rod colliding with the ground, and a rigid thin plate colliding with the ground. The study of the succession of impacts of the rod with the ground confirms results from literature, and explores new cases. Numerical simulations can provide results in the study of the clattering impacts of a 3D body colliding with the ground. For a simplification of the analytical calculations, a rectangular plate without thickness is studied. In this case, a comparison between the numerical method, which is a continuous contact method, and the analytical …

The Influence Of Teacher Expectations On Black And White Students' Academic Achievement: A Hierarchical Linear Modeling Analysis, Syprose A. Owaja

Masters Theses

This study examined the influence of teacher expectations based on student's and teacher's race on academic achievement of white versus black students using data from the National Educational Longitudinal Study. Modeling of interaction terms in level-1 resulted in six separate models (two for reading, and four for math). A two-level hierarchical linear modeling with students at level-1 and schools at level-2 was used in each model with application of a three-step modeling procedure in each analysis.

The results of the study were consistent with previous research that black students had lower achievement, and also elicited lower teacher expectations regarding achievement …

The Global Stratotype Section And Point (Gssp) For The Base Of The Katian Stage Of The Upper Ordovician Series At Black Knob Ridge, Southeastern Oklahoma, Usa, Daniel Goldman, Stephen A. Leslie, Jaak Nõlvak, Seth Young, Stig M. Bergström, Warren D. Huff

Department of Earth, Environment and Sustainability Faculty Publications

The International Subcomission on Ordovician Stratigraphy (ISOS) of the International Commission on Stratigraphy (ICS) recently defined the base of the global Upper Ordovician Series to be at the first appearance datum (FAD) of the graptolite species Nemagraptus gracilis in the Fågelsång GSSP in southern Sweden. This designation recognized the tremendous utility for global correlation of the first appearance of a cosmopolitan taxon that occurs within a consistent succession of other first appearance datums (e.g., Finney and Bergström, 1986; Bergström et al., 2000). Current efforts by the ISOS have focused on subdividing the Upper Ordovician into three stages and choosing appropriate …

Structure And Excitations In Metal Ammonia Compounds, Xue Wang

Dissertations

This work has two parts. In the first part, inelastic x-ray scattering was used to measure the plasmon excitations in liquid lithium ammonia systems. The measurements were carried out for different metal concentrations, 8 mole per metal (MPM), 10 MPM, 11 MPM, 16 MPM and 20 MPM of temperature 200K. The data were analyzed to determine the plasmon energy and the linewidth as a function of momentum for each metal concentration. Deviations from the random phase approximation (RPA) in the jellium model increase as the concentration is lowered.

In the second part of this work, elastic x-ray scattering was used …

Nanosensors For The Detection Of Nerve Agents And Explosives, Deepak Kumar Thimmaraju

Masters Theses

The central hypothesis of this research was development of a novel nanosensor for the detection of nerve agents and explosives. The nanosensor assembly comprises a bottom up approach with nanoparticle (N), monomer (M), nanomolecule (N) and a receptor (R) as moieties of a NMNR assembly. My research was focused on evaluating receptors for their efficiency towards the target analytes such as nerve agents and explosives. Pi electron rich receptor 2-Phenyl-2-Propanol and its fluorinated analog 1,1,1,3,3,3-Hexafluoro-2-Phenyl-2-Propanol were investigated for their ability to detect nerve agents such as DCP, its analogs DMMP and HCl along with the explosives mono, di, and trinitrotoluene. …

研究生助教教學提升方案成效的初步分析, 克忠 林, 榮森 劉, 佩倫 蔡, 菁宜 吳

Journal of Medical Education

研究所學生修業與學術訓練過程裡，常需擔任大學部助教，藉以累積教學經驗，但未曾修習教育相關課程的研究生，在課前通常缺乏教學訓練。有鑑於大學教學卓越的趨勢廣受重視，各大學開始注意研究生助教的培訓，但相關訓練方案的成效報告仍欠缺。本研究針對研究生助教的教學品質，對比事前教學訓練與教學回饋兩種訓練方案，藉以探討兩種訓練方案在教學成效上的差異，以及研究生助教的自評結果。本研究以九十五學年度臺灣大學醫學院職能治療學系碩士班及長庚大學臨床行為科學研究所職能治療組的二十六名研究生助教作為研究樣本，將受試隨機分配至獨立的兩組（各十三人），分別施以「事前訓練」（教學理念與教學方法等團體介紹）與「影片回饋」（依據教學錄影，提供個別回饋與諮商）。研究結果顯示「影片回饋組」在教學意見調查的「表達能力」與「教學效果」兩項，得分顯著優於「事前訓練組」。兩組受試自評結果則無顯著差異。本研究結果支持教學過程的實務回饋，對研究生助教教學能力提升的成效。未來研究值得以更大樣本，進行研究生助教訓練對教學與生涯發展的長期成效。

Synthesis, Study Of Self-Assembly, And Trivalent Lanthanide Metal Ion Recognition Characteristics Of Amphiphilic Acylpyrazolones And Amphiphilic Acylisoxazolones, Venkat Reddy Guduru

Dissertations

This research project focused on the separation of trivalent lanthanide metal ions by HPLC using amphiphilic acylpyrazolones and amphiphilic acylisoxazolones. The central hypothesis of our research project is that the nanoscale self-assembly nature of amphiphilic ligands (chelating lingads) can influence their metal ion recognition and separation. To test the central hypothesis, we have synthesized a family of novel amphiphilic ligands and employed them as model systems for the separation of trivalent lanthanide metal ions. Several novel intermediates such as 4-acylated. N -acylated, O -acylated pyrazolones and isoxazolones, have been efficiently synthesized and fully characterized.*

The trivalent lanthanide metal ion recognition …

Proposing Measures For Assessing Systems Thinking Interventions, Megan Aline Hopper

UNLV Theses, Dissertations, Professional Papers, and Capstones

This paper presents an analysis of systems thinking interventions in educational settings. Although these interventions have been implemented in K-12 classrooms since the mid 1980s, there is still no clear definition of systems thinking or identification of the best method to test the effectiveness of interventions or methods for teaching systems thinking The goal of this paper is to answer the question: how do we assess the effectiveness of systems thinking interventions in education? In order to answer this question, I had to address the following sub questions: (1) what is systems thinking, (2) what systems thinking interventions are being …
