Automated Identification of Relative Clauses in Child Language SamplesMichaelis, Hali Anne 12 February 2009 (has links) (PDF)
Previously existing computer analysis programs have been unable to correctly identify many complex syntactic structures thus requiring further manual analysis by the clinician. Complex structures, including the relative clause, are of interest in child language samples due to the difference in development between children with and without language impairment. The purpose of this study was to assess the comparability of results from a new automated program, Cx, to results from manual identification of relative clauses. On language samples from 10 children with language impairment (LI), 10 language matched peers (LA), and 10 chronologically age matched peers (CA), a computerized analysis based on probabilities of sequences of grammatical markers agreed with a manual analysis with a Kappa of 0.88.

Comparison of P-Delta Analyses of Plane Frames Using Commercial Structural Analysis Programs and Current AISC Design SpecificationsSchimizze, Angela Marie 08 May 2001 (has links)
Several different approaches to determining second-order moments in plane frames were studied during this research. The focus of the research was to compare the moments predicted by four different commercially available computer analysis programs and the current design specification, the AISC LRFD moment magnification method. For this research, the second-order moments for ten commonly designed frames were compared.
An overview of various second-order analysis procedures is presented first. The solution procedure utilized by each computer program and the AISC moment magnification method are explained. Also, the frames considered in the research are described.
Next the frames are analyzed and the results between each of the computer programs and the current design specifications are compared.
Finally, conclusions are drawn concerning the consistency of the second-order moments predicted by each of the solution procedures and recommendations for their use are discussed. In general, each of the four computer analysis programs evaluated and the AISC moment magnification method can consistently and adequately predict the second-order moments in plane frames. / Master of Science

Experimental Evaluation and Computer Analysis of Multi-Spiral Confinement in Reinforced Concrete ColumnsBrubaker, Briana January 1900 (has links)
Master of Science / Department of Civil Engineering / Asadollah Esmaeily / Bridge and building construction in areas that sustain frequent seismic activity require the use of heavy lateral steel reinforcement within concrete columns to handle the lateral loads. Multi-spiral lateral reinforcement has been recently introduced to the construction field to offer an alternative to the traditional hoop and tie reinforcement. This report evaluates the experimental data observed in multiple experimental studies done on different concrete specimens. These specimens include multiple rectilinear reinforcement and several multi-spiral configurations in both rectangular and oblong columns. Due to multi-spiral reinforcement being a relatively new design, traditional computer programs have yet to include design analysis for this type of reinforcement in computer programs. Dr. Asad Esmaeily developed the program KSU RC 2.0 that can implement multiple analytical models to evaluate different multi-spiral configurations, as well as traditional hoop and tie confinement, that may be compared with experimental data. This report illustrates the comparative data from several different reinforced concrete column models. The data clearly indicates that multi-spiral reinforced columns exhibit higher compressive strength in the axial direction as well as higher ductility capabilities when compared to traditional rectilinear reinforcement of similar lateral steel reinforcement ratios. The use of multi-spiral reinforcement is also shown to lower costs for both the work time needed to install the structures as well as lowering the required steel ratio; all while maintaining the structural integrity of the columns.

A computer assisted analysis of literary text : from feature analysis to judgements of literary meritCrosbie, Tess January 2016 (has links)
Using some of the tools developed mainly for authorship authentication, this study develops a toolbox of techniques towards enabling computers to detect aesthetic qualities in literature. The literature review suggests that the style markers that indicate a particular author may be adapted to show literary style that constitutes a "good" book. An initial experiment was carried out to see to what extent the computer can identify specific literary features both before and after undergoing a "corruption" of text by translating and re-translating the texts. Preliminary results were encouraging, with up to 90 per cent of the literary features being identifi ed, suggesting that literary characteristics are robust and quanti fiable. An investigation is carried out into current and historic literary criticism to determine how the texts can be classified as "good literature". Focus groups, interviews and surveys are used to pinpoint the elements of literariness as experienced by human readers that identify a text as "good". Initially identified by human experts, these elements are confirmed by the reading public. Using Classics as a genre, 100 mainly fiction texts are taken from the Gutenberg Project and ranked according to download counts from the Gutenberg website, an indicator of literary merit (Ashok et al., 2013). The texts are equally divided into five grades: four according to the download rankings and one of non- fiction texts. From these, factor analysis and mean averages determine the metrics that determine the literary quality. The metrics are qualified by a model named CoBAALT (computer-based aesthetic analysis of literary texts). CoBAALT assesses texts by Jane Austen and D. H. Lawrence and determines the degree to which they conform to the metrics for literary quality; the results demonstrate conformity with peer reviewed literary criticism.

Towards a Problem-Oriented Library for the Computer Analysis of Stratified Flow PhenomenaElsayed, E.M. 07 1900 (has links)
<p> Flows in channels or estuaries may exhibit variations in density
arising· from differences in temperature, salinity or suspended solids.
In the absence of significant vertical mixing, stable, discrete layers
may form with distinct density interfaces. </p> <p> This thesis presents a computational approach for the analysis of
two-layer, vertically stratified, one-dimensional horizontal flows in
open channels. A variety of such problems are identified and a critical
survey of the existing literature is presented. A framework is defined
against which these problems are classified and decomposed into
analytical problems of the simplest possible scope. Based on the
conditions that lead to changes in flow characteristics, four research
areas are examined. These are energy balance, interfacial hydraulic
jump, lock exchange flows, and long transitions. Although restricted to
essentially one-dimensional flows, the analytical study of these four
areas is extended to allow for non-uniform velocity distribution the
introduction of boundary-layer displacement thicknesses and correction
factors for kinetic energy and momentum. Also, a significant feature of
the study is the ability to handle channels of arbitrary cross-sectional
geometry. </p> <p> The basic philosophy of the approach followed in this study is to
develop a relatively simple and computationally econaoical procedure
which is applicable to a wide variety of problems involving channels systems of arbitrary geometry and boundary conditions. A library of
computer subroutines provides a convenient means of developing an
open-ended system of computational techniques for the solution of a wide
range of problems. Such a library of computational algorithms may also
promote. cooperation and collaboration among researchers and engineers
concerned with stratified flow hydraulics. Such algorithms should
provide solutions for frequently recurring problems, should be mutually
compatible and allow the construction of relatively complex analytical
models in a modular fashion. A comprehensive library of routines is
developed which consists of fourty-four subroutines and functions. This
evolves as a well-defined hierarchy of algorithms in which the most
basic algorithms are nested within the more sophisticated ones to the
sixth or seventh level. </p> <p> The computational algorithms are tested for theoretical and computational performance. Numerical predictions are compared with
available experimental and field data. Moreover, an experimental
program is described which is designed and carried ·out to verify the
numerical predictions obtained for the first of the above-mentioned four
topics. </p> <p> An important aspect of the study is the illustration of the
application of the routines in the solution of typical practical
problems such as selective withdrawal from stratified water bodies and
recirculation of cooling water from power plants. In addition, to
facilitate utilization of the programs by others, complete documentation
and listings are provided. </p> / Thesis / Doctor of Philosophy (PhD)

The role of qualitative methods in production management research.Beach, Roger, Muhlemann, Alan P., Price, D.H.R., Paterson, A., Sharp, J.A. January 2001 (has links)
No / This paper examines previous approaches to the identification and measurement of strategic flexibility and concludes that the use of quantitative methods alone cannot capture the essence of such a complex and intangible subject. It is reasoned that a holistic approach to research design should be adopted when carrying out particular categories of production management research. A research design used to investigate the concept of strategic flexibility in manufacturing industry is briefly outlined as an illustration. The role of the case study within this and the contribution it was able to make to the investigation is described.

Computational Analysis For Performance Prediction Of Stirling CryocoolersCakil, Semih 01 December 2010 (has links) (PDF)
Stirling cryocoolers are required for a wide variety of applications, especially in military equipment, due to their small size, low weight, long lifetime and high reliability considering their efficiency. Thus, it is important to be able to investigate the operating performance of these coolers in the design stage.
This study focuses on developing a computer program for simulating a Stirling cryocooler according to the second order analysis. The main consideration is to simulate thermodynamic, fluid dynamic and heat transfer behavior of Stirling cryocoolers. This goal is achieved by following the route of Urieli (1984), which was focused on Stirling cycle engines.
In this research, a simulation for performance prediction of a Stirling cryocooler is performed. In addition to that, the effects of system parameters are investigated. This attempt helps to understand the real behavior of Stirling cryocoolers using porous regenerator material. Results implied that first order analysis methods give optimistic predictions where second order method provides more realistic data compared to first order methods. In addition to that, it is shown that regenerator porosity has positive effect on heat transfer characteristics while affecting flow friction negatively.
As a conclusion, this study provides a clear understanding of loss mechanisms in a cryocooler. Performed numerical analysis can be used as a tool for investigation of
effects of system parameters on overall performance.
