Lexical processing in children and adults during word copying.
No full textCopying text may seem trivial, but the task itself is psychologically complex. It involves a series of sequential visual and cognitive processes, which must be co-ordinated; these include visual encoding, mental representation and written production. To investigate the time course of word processing during copying, we recorded eye movements of adults and children as they hand-copied isolated words presented on a classroom board. Longer and lower frequency words extended adults' encoding durations, suggesting whole word encoding. Only children's short word encoding was extended by lower frequency. Though children spent more time encoding long words compared to short words, gaze durations for long words were extended similarly for high- and low-frequency words. This suggested that for long words children used partial word representations and encoded multiple sublexical units rather than single whole words. Piecemeal word representation underpinned copying longer words in children, but reliance on partial word representations was not shown in adult reader
Numerical Analysis of Damage Iinitiation and Development in Bends of Steel Pipelines
No full textGasses and fluids are transported via an extensive infrastructure of steel pipelines. In the design of pipeline systems the use of elbows (pipe bends) is important because their flexibility makes them able to sustain significant deformations. These bends can be subjected to permanent deformations due to various load combinations which can lead to progressive material damage. There are three stages commonly observed in ductile damage: void nucleation, growth and coalescence. When subjected to varying bending loads low cycle fatigue damage may occur. Within this research project Finite Element Analysis is used to simulate the response of pipeline bends. Two element types are implemented to model a pipe bend, the classical shell element and an efficient tube element (pipe elbow element), respectively. To predict the structural response when subjected to monotonic loading a damage model is implemented for both elements. When subjected to cyclic loading three phases can be identified. During the first few cycles the permanent deformation increases rapidly. After some cycles, the rate of permanent deformation stabilizes until the point of response degradation. In order to capture this response a new material model, based upon the afore mentioned model, is proposed. Experiments have indicated that this model is well suited to determine the point of material failure.Structural MechanicsCivil Engineering and Geoscience

The A.E. Coppard Papers at Syracuse
No full textSome of the most choice collections in the Manuscript Department of Syracuse University Libraries are also among the most modest in extent. The papers of English author and poet A.E. Coppard fit into both categories. Housed comfortably in a single box, fifty-five letters, three short stories in holograph and one speech provide a close look at Coppard\u27s literary theories, criticism, opinions of his own work and that of a few others, reaction to approaches regarding dramatizing, filming or televising his prose works, dealings with publishers, and his activities on behalf of world peace through the Authors\u27 World Peace Appeal in the early 1950\u27s
Stability of singular spectral types under decaying perturbations
No full textAbstractWe look at invariance of a.e. boundary condition spectral behavior under perturbations, W, of half-line, continuum or discrete Schrödinger operators. We extend the results of del Rio, Simon, Stolz from compactly supported W's to suitable short-range W. We also discuss invariance of the local Hausdorff dimension of spectral measures under such perturbations
