Résumé :

The ability to extract figures and tables from scientific documents can solve key use-cases such as their semantic parsing, summarization, or indexing. Although a few methods have been developed to extract figures and tables from scientific documents, their performance on scanned counterparts is considerably lower than on born-digital ones. To facilitate this, we propose methods to effectively extract figures and tables from Electronic Theses and Dissertations (ETDs), that out-perform existing methods by a considerable margin. Our contribution towards this goal is three-fold. (a) We propose a

Résumé :

Seven very luminous galaxies were examined to determine the contribution of active nuclei to their luminosity, the nature of their stellar population, and the validity of previous measurements of their H₂ content. Spectra of the 2.3 μm bands of CO were used to measure the stellar velocity dispersion, and hence the mass in the central regions. The bolometric luminosity, ionizing continuum luminosity, CO index, and 2.2 μm luminosity were also determined. Models of young stellar populations were compared to the observed properties of the galaxies. It was found that four of the seven galaxies have

Résumé :

Pancreatic carcinoma or pancreatic cancer (PaCa) is an insidious disease with a prognosis of 6- to 12-month survival time for a late stage diagnosis. This problem has become crucial given that no study to date had been able to establish a definitive association between independent factors (other than a few diseases) and the survival rate of pancreatic cancer. The purpose of this quantitative, cross-sectional study was to determine whether an association exists between the independent, sociodemographic variables (marital status, age, education, income, and employment) and the outcome variable o

Educational access, achievement and opportunity for students and educators in U.S. educational institutions is influenced and often limited by gender. Although the U.S. Glass Ceiling Commission reports that the gender equity values, beliefs and commitments of institutional leaders are a key factor in reducing institutional gender inequities (U.S. Dept of Labor, 1995), very little is known about the current preparation or evaluation of educational leadership values, especially at the doctoral level (Hess & Kelly, 2007, Grogan & Andrews, 2002; Levine, 2005; Murphy & Vriesenga, 2004).

We present near-infrared images of nearly 100 host galaxies of Active Galactic Nuclei (AGN). Our quasar sample is comprised of the 50 quasars from the Palomar Green Bright Quasar Survey with redshifts z ≤ 0.3. We have restricted the redshift range to ensure adequate spatial resolution, galaxy detectability, and minimal distance-dependent effects, while still giving a large sample of objects. For lower-luminosity AGN we have chosen to image the CfA Seyfert sample. This sample is composed of 48 Seyferts, roughly equally divided among types 1, 1.5-1.9, and 2.

There is a labyrinth of complex social connections between people and places that deserves careful anthropological reflection.

Anthropology is currently experiencing a resurging emphasis on place that seeks to account for its remarkably social features.

Compounds that result in an increase in Picogreen staining represent potential topoisomerase interfacial poisons while those that reduce fluorescence report catalytic inhibitors; therefore, the solid phase assay represents a 'bimodal' readout that reveals mechanisms of acti

University of Central Florida College of Engineering Thesis<br>Psychological testing has shown that there is an early preattentive stage in the human visual system. At this level, simple features and properties of objects known as visual primitives are deteched spatially in parallel by groupings of cells in the visual cortex known as feature maps. In order to study this preattentive stage in a machine vision system, the biologically inspired, highly parallel architecture of the artificial neural network shows great promise. This paper describes how the unique architecture of the counterprop

Résumé :

University of Central Florida College of Education Thesis<br>Child growth and development pedagogy suggests that not all children are ready to learn the same thing, at the same time, in the same way. Multiage/nongraded programs allow pupils to advance from one concept or skill level to the next as they are ready, regardless of age or grade, which results in continuous progress. Multiage/nongraded education has a solid foundation or research and experience to support its use. However, many questions still exist regarding the factors that contribute to the implementation of a successful prima

Résumé :

University of Central Florida College of Engineering Thesis<br>A desirable goal of military simulation training is to provide large scale or joint exercises to train personnel at higher echelons. To help meet this goal, many of the lower echelon combatants must consist of computer generated forces with some of these echelons composed of units from different simulations. The object of the research described is to correlate the behaviors of entities in different simulations so that they can interoperate with one another to support simulation training. Specific source behaviors can be translat

University of Central Florida College of Education Thesis<br>The purpose of this study was to discover and interpret reasons Florida parents enrolled their children in Islamic schools. A selection of 30 parents from 3 different schools in Florida were interviewed by the researcher using a semistructured interview guide which used both oral and written responses. The sample was matched according to the gender of parents interviewed - 15 mothers and 15 fathers were interviewed. the sample was matched according to the gender of the referent child.

Résumé :

University of Central Florida College of Engineering Thesis<br>The use of an accepted logical database design tool, Entity-Relationship Diagrams (E-RD), is explored as a method by which conceptual and pseudo-conceptual knowledge bases may be designed. Extensions to Peter Chen's classic E-RD method which can model knowledge structure used by knowledge-based applications are explored. The use of E-RDs to design knowledge bases is proposed as a two-stage process. In the first stage, and E-RD, termed the Essential E-RD, is developed of the realm of the problem or enterprise being modeled. The

The second SBR, the Isovaleric SBR, was run for three months. During the first month, isovaleric acid was its supplemental carbon source while for the remaining time period, no supplemental carbon source was added to the feed. Steady-state data fr
