Cs 790-01: Knowledge Representation For The Semantic Web, Pascal Hitzler 2010 Wright State University - Main Campus

Cs 790-01: Knowledge Representation For The Semantic Web, Pascal Hitzler

Computer Science & Engineering Syllabi

Semantic Web is a maturing field of technology that continues to be the emphasis of much focused research and industrial investigation. The central idea behind Semantic Web is to enhance data on the World Wide Web by so-called metadata, which describes the meaning (semantics) of the data and thus makes it available for processing in intelligent systems. In this course we cover in depth the standardized knowledge representation languages for expressing metadata, called ontology languages. We will in particular cover the Resource Description Framework RDF and the Web Ontology Language OWL, both of which are recommended standards by the World ...

Simulating Human Activities For Synthetic Inputs To Sensor Systems, Jan Allbeck, Norman I. Badler 2010 University of Pennsylvania

Simulating Human Activities For Synthetic Inputs To Sensor Systems, Jan Allbeck, Norman I. Badler

Departmental Papers (CIS)

We are developing human activity simulations that could be used to test distributed video sensor networks. Our ultimate goals are to build statistical models of pedestrian density and flows at a number of urban locations and to correlate those flows with population movement and density models represented in a spatiotemporal modeling system. In order to create known populace flows, we have built a virtual populace simulation system, called CAROSA, which permits the authoring of functional crowds of people going about role-, context-, and schedule-dependent activities. The capabilities and authoring tools for these functional crowd simulations are described with the intention ...


Empirical Limitations On High Frequency Trading Profitability, Michael J. Kearns, Alex Kulesza, Yuriy Nevmyvaka 2010 University of Pennsylvania

Empirical Limitations On High Frequency Trading Profitability, Michael J. Kearns, Alex Kulesza, Yuriy Nevmyvaka

Departmental Papers (CIS)

Addressing the ongoing examination of high-frequency trading practices in financial markets, we report the results of an extensive empirical study estimating the maximum possible profitability of the most aggressive such practices, and arrive at figures that are surprisingly modest. By “aggressive” we mean any trading strategy exclusively employing market orders and relatively short holding periods. Our findings highlight the tension between execution costs and trading horizon confronted by high-frequency traders, and provide a controlled and large-scale empirical perspective on the high-frequency debate that has heretofore been absent. Our study employs a number of novel empirical methods, including the simulation of ...


Structural Features For Predicting The Linguistic Quality Of Text: Applications To Machine Translation, Automatic Summarization And Human-Authored Text, Ani Nenkova, Jieun Chae, Annie Louis, Emily Pitler 2010 Univesity of Pennsylvania

Structural Features For Predicting The Linguistic Quality Of Text: Applications To Machine Translation, Automatic Summarization And Human-Authored Text, Ani Nenkova, Jieun Chae, Annie Louis, Emily Pitler

Departmental Papers (CIS)

Sentence structure is considered to be an important component of the overall linguistic quality of text. Yet few empirical studies have sought to characterize how and to what extent structural features determine fluency and linguistic quality. We report the results of experiments on the predictive power of syntactic phrasing statistics and other structural features for these aspects of text. Manual assessments of sentence fluency for machine translation evaluation and text quality for summarization evaluation are used as gold-standard. We find that many structural features related to phrase length are weakly but significantly correlated with fluency and classifiers based on the ...

About The Chemistry Of The Terminating 5f-Planes In I-Alpdmn : A Comparison Between Models And Surface Studies, M. Quiquandon, Baris Unal, Patricia A. Thiel, D. Gratias

Chemistry Conference Papers, Posters and Presentations

Structural arguments are proposed that support the hypothesis that the equilibrium 5f-surfaces of i-AlPdMn icosahedral alloys are actual cuts of the bulk structure with almost pure Al termination planes [1, 2] corresponding to actual bulk properties with no need for possible Al segregation on the surface. Most of the 5f termination planes in i-AlPdMn are made of two close planes containing essentially Al at the upper one and Al and Pd at the second one (see for instance [3]). Here, perfect unrelaxed structural models that differ only in the chemical distribution of the atomic species are devised, close to the ...


Toward A Whole-Landscape Approach For Sustainable Land Use In The Tropics, R. DeFries, C. Rosenzweig 2010 Columbia University

Toward A Whole-Landscape Approach For Sustainable Land Use In The Tropics, R. Defries, C. Rosenzweig

NASA Publications

Increasing food production and mitigating climate change are two primary but seemingly contradictory objectives for tropical landscapes. This special feature examines synergies and trade-offs among these objectives. Four themes emerge from the papers: the important roles of both forest and agriculture sectors for climate mitigation in tropical countries; the minor contribution from deforestation-related agricultural expansion to overall food production at global and continental scales; the opportunities for synergies between improved food production and reductions in greenhouse gas emissions through diversion of agricultural expansion to already-cleared lands, improved soil, crop, and livestock management, and agroforestry; and the need for targeted policy ...


Super-Resolution Using Adaptive Wiener Filters, Russell C. Hardie 2010 University of Dayton

Super-Resolution Using Adaptive Wiener Filters, Russell C. Hardie

Electrical and Computer Engineering Faculty Publications

The spatial sampling rate of an imaging system is determined by the spacing of the detectors in the focal plane array (FPA). The spatial frequencies present in the image on the focal plane are band-limited by the optics. This is due to diffraction through a finite aperture. To guarantee that there will be no aliasing during image acquisiton, the Nyquist criterion dictates that the sampling rate must be greater than twice the cut-off frequency of the optics. However, optical designs involve a number of trade-offs and typical imaging systems are designed with some level of aliasing. We will refer to ...

Electrical and Computer Engineering Faculty Publications

We describe preliminary results of a set of laser beam propagation experiments performed over a long (149 km) near-horizontal propagation path between Mauna Loa (Hawaii Island) and Haleakala (Island of Maui) mountains in February 2010. The distinctive feature of the experimental campaign referred to here as the Coherent Multi-Beam Atmospheric Transceiver (COMBAT) experiments is that the measurements of the atmospheric-turbulence induced laser beam intensity scintillations at the receiver telescope aperture were obtained simultaneously using three laser sources (laser beacons) with different wavelengths (λ1 = 0.53 μm, λ2 = 1.06 μm, and λ3 = 1.55 μm). The presented experimental results on ...

Open Policy For Wireless Computers In Classrooms: What Makes It A Good Or A Bad Idea?, Zdeslav Hrepic, Kimberly Shaw 2010 Columbus State University

Open Policy For Wireless Computers In Classrooms: What Makes It A Good Or A Bad Idea?, Zdeslav Hrepic, Kimberly Shaw

Faculty Bibliography

Increasingly, studies and media articles have been looking into possible adverse effects of open policies for using wireless ready computers in classrooms. Tablet PCs, as indicated by some of those authors, are under suspicion more than laptops because they make it harder for instructor to determine whether they are used productively or for off-the-task purposes. In this study students were invited to voluntarily bring their personal wireless computers to introductory physics classes in order to utilize them with DyKnow software. We compare performance of students who consistently used computers in classroom with those who did so less frequently or not ...
