A Multi-Platform Application Suite For Enhancing South Asian Language Pedagogy, Tao Bai, Christopher K. Chung, Konstantin Läufer, Daisy Rockwell, George K. Thiruvathukal

Computer Science: Faculty Publications and Other Works

This interdisciplinary project explores the potential for handheld/wireless (H/W) technology in the context of language education within and beyond the classroom. Specifically, we have designed and implemented a suite of multi-platform (desktop/laptop, handheld, and browser) applications to enhance the teaching of South Asian languages such as Hindi-Urdu. Such languages are very difficult to learn, let alone write, and H/W devices (with their handwriting/drawing capabilities) can play a significant role in overcoming the learning curve. The initial application suite includes a character/word tracer, a word splitter/joiner, a smart flashcard with audio, contextual augmented stories for reading comprehension, and a poetic metronome. …

Scalable Implementations Of Mpi Atomicity For Concurrent Overlapping I/O, Wei-Keng Liao, Alok Choudhary, Kenin Coloma, George K. Thiruvathukal, Lee Ward, Eric Russell, Neil Pundit

Computer Science: Faculty Publications and Other Works

For concurrent I/O operations, atomicity defines the results in the overlapping file regions simultaneously read/written by requesting processes. Atomicity has been well studied at the file system level, such as POSIX standard. In this paper, we investigate the problems arising from the implementation of MPI atomicity for concurrent overlapping write access and provide a few programming solutions. Since the MPI definition of atomicity differs from the POSIX one, an implementation that simply relies on the POSIX file systems does not guarantee correct MPI semantics. To have a correct implementation of atomic I/O in MPI, we examine the efficiency of three …

Judging Distance Across Texture Discontinuities, Cary S. Feria, M. L. Braunstein, G. J. Andersen

Faculty Publications

Sinai et al (1998 Nature 395 497 - 500) showed that less distance is perceived along a ground surface that spans two differently textured regions than along a surface that is uniformly textured. We examined the effect of texture continuity on judged distance using computer-generated displays of simulated surfaces in five experiments. Discontinuities were produced by using different textures, the same texture reversed in contrast, or the same texture shifted horizontally. The simulated surface was either a ground plane or a frontoparallel plane. For all textures and both orientations, less distance was judged in the discontinuous conditions than in continuous …

Understanding Formative Assessment In Extended Classroom Curricular Interaction, John Gulliver

Plymouth Institute of Education Theses

This thesis relates to the debates about assessment in education that marked the final years of the 20th century. It attends to the assertion, widely made in policy pronouncements within and beyond the UK, at every level of the education system, that assessment is an integral part of teaching, pronouncements seen by some writers as rhetoric-driven and atheoretical. It focuses in particular on formative assessment, with its underlying assumption that, to be effective, teaching must match the cognitive requirements of learners. The study examines the psychological and epistemological foundations of this assertion, contends that both are problematic, and confirms that …

Novel Techniques For Investigating The Permeation Properties Of Environmentally-Friendly Paper Coatings: The Influence Of Structural Anisotropy On Fluid Permeation In Porous Media, Paul Bodurtha

School of Geography, Earth and Environmental Sciences Theses

In this study, we have investigated the effects of structural anisotropy of porous media on the permeation of fluids. The motivation for the work was an increased understanding of the permeation of inks into paper coatings, which often contain platey or needle-like particles, which have been aligned during the coating process. However, the findings are also relevant to other systems, such as the sub-terranean migration of fluids, including pollutants, within shale that contains particles of high aspect ratio. Mineral pigments, comprising mainly of calcium carbonate or clay, are often are applied to the surface of paper to improve optical and …

Characterisation Of Nitric Oxide Synthase Activity In The Sea Anemone Aiptasia Pallida And An Evaluation Of Responses To Environmental Stress, Clare Emma Morrall

School of Geography, Earth and Environmental Sciences Theses

Studies were undertaken to investigate the presence of nitric oxide synthase (NOS; E.C. 1.14.13.39) activity in number of cnidarian species from shallow marine subtropical environments. Enzyme activity was assayed by measuring the conversion of 3H L-arginine to 3H L-citrulline (the citrulline assay). This assay was shown to be sufficiently sensitive for studies of this nature but was not optimised for use with cnidarian preparations. As a result, confidence in the accuracy of the generated assay results is limited. NOS activity was nevertheless demonstrated in the sea anemone A. pallida, in the zooxanthellae associated with A. pallida, Symbiodinium spp. and in …

Sediment Transport And Morphodynamics At An Estuary Mouth: A Study Using Coupled Remote Sensing And Numerical Modelling, Eduardo Siegle

School of Geography, Earth and Environmental Sciences Theses

The balance of the physical processes that drive the morphodynamics of a complex inlet system is investigated in this work. For this purpose, an innovative technique using coupled video imaging and numerical modelling has been used to study the relative importance of the driving forces that control the sandbar dynamics at the Teignmouth inlet system. The sandbars that form the ebb tidal delta are highly dynamic, leading to a cyclic morphological behaviour. Application of the numerical model (MIKE21 HD, NSW, ST) served two separate functions. The hydrodynamic model has been used for the image processing and, combined with the sediment …

Automatic Statistical Processing Of Multibeam Echosounder Data, Brian R. Calder

Center for Coastal and Ocean Mapping

This paper presents the CUBE (Combined Uncertainty and Bathymetry Estimator) algorithm. Our aim is to take advantage of statistical redundancy in dense Multibeam Echosounder data to identify outliers while tracking the uncertainty associated with the estimates that we make of the true depth in the survey area. We recognise that a completely automatic system is improbable, but propose that significant benefits can still be had if we can automatically process good quality data, and highlight areas that probably need further attention. We outline CUBE and its associated support structures, and apply it to a dataset from Woods Hole, MA, USA. …

The Role Of Acute Normovolaemic Haemodilution In Gastro-Intestinal Surgery, Grant Sanders

Other Faculty of Health Theses

Background: Allogeneic transfusion confers a risk to the recipient and the recent introduction of leucocyte depleted blood has increased cost pressure on health resources. Colorectal surgery is a high blood usage field with 43% of all patients in our unit being transfused, over a three year period. Patient perceptions: Despite the risks associated with transfusion, a majority of patients are willing to have an allogeneic transfusion (85%) and think it is safe (89%), which may have implications in the uptake of alternatives available. The effect of bowel preparation Picolax bowel preparation causes significant dehydrating effects which may impair acute normovolaemic …

Philosophies Of Colour: Gender And Acculturation, Helen V Andrew

Other Faculty of Arts, Humanities and Business Theses

My hypothesis is that 'Colour' as idea acts as a dynamic in the production of meaning and as such is part of what Le Doeuff (1991: 46-49) argues are deeply held epistemes that structure and govern our ways of thinking. I have dealt with the difficulties attendant on the analysis of a phenomenon as insubstantial as colour (as idea and as precept) by assuming Goethe's (1810: 305-323) concept of the enrobement of colour to objects without also attaching Goethe's theoretical hypothesis of moral associations to colour. Thus I combine four different methodologies to broadly related areas and cloak each in …

Indentity-In-Motion : The Narrative Duration Of The Dis/Continous Film Moment, Maria Walsh

Other Faculty of Arts, Humanities and Business Theses

The trajectorv of this thesis is set out like a journey upon which encounters are staged between two films. film theor), and philosophers. such as Slavoj Zizek. Gilles Deletize, and Maurice Merleau-Ponty. An encounter with a moment of image suspension. a cut to the blank screen- in Tacita Dean's film, Disappearance atSea (1996). motivates the beginning of this journey's narrative. My reading of this moment counters the way that suspended film moments have been discussed in terms of non-narrative in 1970s film theory and in the contemporary psychoanalýlic filin theory of Slavoj Zizek. Using Gilles Deleuze's notion of narrativization as …

From 'Le Cri De La Nature' To 'Pygmalion' : A Study Of Jean-Jacques Rousseau's Philosophy Of Music And Aesthetic And Reform Of Opera, Stephen John Xavier Baysted

Other Faculty of Arts, Humanities and Business Theses

The thesis sets Rousseau's philosophy of music and aesthetic of opera against the wider philosophical backcloth of eighteenth-centuryF rance and in contraposition to the more scopic music-theoredcabl ackdrop,o f which Rameau'sw ritings are takena s a paradigm. The first half of the thesis contends that the philosophy of music is fashioned upon a trinary model which mirrors the philosophy of nature and history. The first sector is an ideal, hypothetical state; the second (the 'fall) is the moment when the ideal state is ruptured, when societal and cultural institutions - and history - commence; the third, is the 'actual state', …

Advances In The Use Of Neurophysiologycally-Based Fusion For Visualization And Pattern Recognition Of Medical Imagery, Mario Aguilar, Joshua New, Erion Hasanbelliu

Research, Publications & Creative Work

The ever increasing number of image modalities available to doctors for diagnosis purposes has established an important need to develop techniques that support work-load reduction and information maximization. To this end, we have improved on an image fusion architecture first developed for night vision applications. This technique, presented at Fusion 2002, utilizes 3D operators to combine volumetric image sets while maximizing information content. In our approach, we have combined the use of image fusion and userdefined pattern recognition within a 3D human-computer interface. Here, we present our latest advances towards enhancing information visualization and supporting pattern recognition. We also report …

Mapping And Characterizing Subtidal Oyster Reefs Using Acoustic Techniques, Underwater Videography And Quadrat Counts, Raymond E. Grizzle, J R. Adams, Semme J. Dijkstra, Brian Smith, R W. Ward

Center for Coastal and Ocean Mapping

Populations of the eastern oyster Crassostrea virginica have been in long-term decline in most areas. A major hindrance to effective oyster management has been lack of a methodology for accurately and economically obtaining data on their distribution and abundance patterns. Here, we describe early results from studies aimed at development of a mapping and monitoring protocol involving acoustic techniques, underwater videography, and destructive sampling (excavated quadrats). Two subtidal reefs in Great Bay, New Hampshire, were mapped with side-scan sonar and with videography by systematically imaging multiple sampling cells in a grid covering the same areas. A single deployment was made …

Development And Modelling Of A Point Source Integrating Cavity Absorption Meter (Psicam), Christophe Jean-Yves Joel Lerebourg

School of Biological and Marine Sciences Theses

The absorption coefficient is a fundamental parameter in understanding the underwater light field, for solving the Radiative Tranfer Equation and understanding/interpreting remotely sensed data from the ocean. Measuring the absorption coefficient is particularly complicated in coastal areas where the optical properties of the water body are the result of a complex mixture of dissolved and particulate components, but mainly because of the interfering effect that scattering has upon the measurements. A great variety of in situ instruments and laboratory techniques have been developed to measure total absorption or the absorption by the various fractions that constitute the total absorption. They …

Reading Between The "Signs", Sarah Durchenwald/Williamson

Graduate Research Papers

Teaching reading to hearing students, with the supplemental support of American Sign • Language, is a relatively new concept. Many components associated with sign language reinforce basic concepts of English. It teaches individual letter sounds, and names, and many of the signs for words emphasize beginning sounds, as well as meaning. Another important component of sign language is its bodily kinesthetic form of learning. Many students in public schools today are not learning through traditional teaching strategies. Incorporating sign language provides a multi-sensory approach to literal hands-on learning.

The following research outlines the principles behind teaching effectively using sign language …

Creating A Successful Online Class In An Alternative Educational Environment, Cathy L. Lewis

Graduate Research Papers

This paper's objective was to describe how creating an online class for alternative education students could benefit school districts. Alternative education is a continuing problem for school districts. Small school districts have difficulty affording alternative education environments. Online alternative programs also benefit students. Creating an online learning environment allows students to work at their own pace, stay in touch with their class, and perform at their own level. This paper's conclusions indicate alternative education programs can benefit through the creation of online classes.

Us Nuclear Security Cooperation With Russia And Transparency, David W. Hafemeister

Physics

This chapter reviews the efforts of Russia and the United States to conclude agreements on the control or reduction of their inventories of nuclear warheads and military fissile materials. While some of the negotiations attempted to codify arms limitation and reduction measures, others were aimed at constraining the spread of fissile materials and technologies to the non-nuclear weapon states (NNWS). A number of the negotiations had elements of both arms control and non-proliferation.

Most of the monitoring provisions contained in nuclear agreements between Russia and the USA are in the category of transparency measures—those that give confidence that a …

Developmental Financial Institutions As Technology Policy Instruments: Implications For Innovation And Entrepreneurship In Emerging Economies, Gerard George, Ganesh N. Prabhu

Research Collection Lee Kong Chian School Of Business

Developmental financial institutions (DFIs) in emerging economies regularly assess new technology platforms to support their investments in new ventures, established firms, and technology institutions (TIs). Their financing decisions are guided by national priorities such as achieving technological self-reliance. By providing attractive financing options and related support, DFIs are well placed to consciously channel finance into designated priority technology areas. To better understand DFI roles, we conducted multiple interviews with participants affiliated with DFIs, firms and TIs in India. From data gathered from these interviews and secondary data on DFIs in emerging economies, we develop a preliminary framework to suggest that …

Afm, Cafm, And Efm Studies Of The Gan System, John C. Dickinson

Theses and Dissertations

This thesis discusses a variety of techniques based on the atomic force microscope (AFM), and their application to the GaN materials system. In particular, the local conductivity and contact potential of surfaces have been measured using the techniques of Conductive AFM (CAFM) and Surface Potential Electric Force Microscopy (SPEFM), respectively. CAFM studies of GaN surfaces have revealed that prismatic planes around islands and pits on surfaces can lead to enhanced conductivity, which may be related to leakage problems in device applications. With regard to SP-EFM work, the change in surface potential associated with inversion domains on Ga-polar GaN has been …

Normal Mixture Models For Gene Cluster Identification In Two Dimensional Microarray Data, Eric Scott Harvey

Theses and Dissertations

This dissertation focuses on methodology specific to microarray data analyses that organize the data in preliminary steps and proposes a cluster analysis method which improves the interpretability of the cluster results. Cluster analysis of microarray data allows samples with similar gene expression values to be discovered and may serve as a useful diagnostic tool. Since microarray data is inherently noisy, data preprocessing steps including smoothing and filtering are discussed. Comparing the results of different clustering methods is complicated by the arbitrariness of the cluster labels. Methods for re-labeling clusters to assess the agreement between the results of different clustering techniques …
