A Study For The Development Of Seismic Design Specifications For Coastal Structures

Gozpinar, Erdem 01 January 2003 (has links) (PDF)
An evolving design philosophy for port structures in many seismically active regions reflects the observations that: -The deformations in ground and foundation soils and the corresponding structural deformation and stress states are key design parameters. -Conventional limit equilibrium-based methods are not well suited to evaluating these parameters. -Some residual deformation may be acceptable. Performance-based design is an emerging methodology whose goal is to overcome the limitations present in conventional seismic design. Conventional building code seismic design is based on providing capacity to resist a design seismic force, but it does not provide information on the performance of structure when the limit of the force-balance is exceeded. If we demand that limit equilibrium not be exceeded for the relatively high intensity ground motions associated with a rare seismic event, the construction cost will most likely be too high. If forcebalance design is based on amore frequent seismic event, then it is difficult to estimate the seismic performance of the structure when subjected to ground motions that are greater than those used in design. In this thesis a case study will be carried out on a typical port structure to show the performance evolution aspects and its comparison with damage criteria and performance grade in performance-based methodology.

Calibrating Intuition: A Defense of Standard Philosophical Analysis

Jalea, Justin 11 1900 (has links)
Intuition has fallen from grace. Its authority to act as a source of evidence in philosophical discourse has recently been called into question by philosophers and cognitive psychologists alike, who claim that because of the many difficulties that plague intuition, it should not hold the evidential role it does presently. This is exceedingly troubling, since appeals to intuition are pervasive throughout, and infiltrate every level of, philosophical discourse. This paper explores the extent of intuitions infiltration in philosophy and whether intuition is warranted in those positions. I argue that by focusing on virtues exhibited by philosophical methodology, many of the arguments made against them are defused. In spite of this, we can largely carry on utilizing the methodology which houses intuitions Standard Philosophical Analysis while continually attempting to revise and refine that methodology.

Variation and change in university teachers' ways of experiencing teaching

January 2003 (has links)
This thesis explores how university teachers' ways of experiencing teaching change from teacher focused to student focused and why some teachers experience this change while others do not. The exploration adopts the theoretical perspective of variation, learning and awareness (Marton and Booth, 1997) and is based on a two-year longitudinal interview study of 27 university teachers. Classical and new phenomenographies were used to constitute teachers' ways of experiencing teaching and teachers' ways of experiencing change in teaching. Changes in individual teachers' ways of experiencing were described and interpreted through focusing on teachers' awareness of critical aspects and related dimensions of variation, creating individual vignettes, and constituting themes in the critical experiences and orientations related to change. The outcomes included six ways of experiencing teaching and their complementary patterns of critical aspects, a set of themes related to change in ways of experiencing and five ways of experiencing change in teaching. Combining these outcomes resulted in four patterns which illuminated why some teachers' ways of experiencing teaching became student focused while others remained teacher focused. Teachers who became capable of experiencing teaching in student-focused ways focused on understanding teaching in relation to students' learning. They experienced change in teaching as becoming more student-focused or as relating teaching to development or change in student understandings, and were oriented towards putting teaching into focus and reflecting in ways informed by formal learning. These teachers experienced relevance structures which brought the critical aspects of student-focused ways of experiencing teaching to the foreground of their awareness so that they experienced corresponding dimensions of variation. Their awareness of teaching expanded and this corresponded to a shift in the focus and meaning of teaching.

The Construction of the Meaning and Significance of an 'Author' among Information Behaviour Researchers. A Social Constructivist approach.

January 2003 (has links)
This study identifies and explores the social processes that influence the construction by academic researchers of the meaning/s and significance/s of an author and her work prominent in the literature of their field. It examines the construction by 15 information behaviour researchers of Brenda Dervin and her work, using semi-structured interviewing and inductive analysis techniques. In focussing theoretical attention on social processes, the study seeks to address critiques of prevailing approaches to information behaviour research, such as: a focus on individual cognition at the expense of social and affective factors; a construction of information users defined by their areas of ignorance and uncertainty, rather than their expertise; and a focus on purposive rather than non-purposive information behaviour. Conceptually, the study has been influenced by a range of theoretical approaches from both information behaviour research and a variety of other disciplines, including Dervin's Sense-Making and Foucauldian discourse analysis. The study found that participants' initial contact with the author and her work, and the subsequent important events in their relationship, occurred not because of purposeful searching, but rather 'socially' - as a part of non-purposive events and relationships related to the participants' role as academic researchers. The source most frequently discussed by participants was informal discussions with colleagues, and participants' interactions with 'author texts' were commonly mediated by their interpersonal communication. The study found that the significant influences on participants' constructive processes were people and texts with whom they had a long-term relationship. Participants' constructions of the author and her work were an essentially social process. Their sense-making was inextricably linked to their social context/s: their interactions with their colleagues and mentors; their engagement with the literature and theories of information science and other fields; their research interests and specialisations; and their educational and cultural backgrounds. Participants' constructive processes largely involved elaborating existing constructions - radical changes in construction were both rare and traumatic. Participants' constructions were neither objective nor wholly subjective, but intersubjective - based on shared understandings, conventions and social practices. Participants' constructive processes had two interdependent aspects: the construction of meaning and the construction of authority (knowledge/power). Participants' informal behaviour, as well as their engagement with formal information sources, involved constructions of authority. Their constructions of the authority of their informant/s determined whether they accepted or rejected the constructions of the author conveyed to them. Participants were able to strategically use shared constructions to add to the credibility and authority of their own work

Reuse of industrial products - a technical and economic model for decision support

Anityasari, Maria, Mechanical & Manufacturing Engineering, Faculty of Engineering, UNSW January 2008 (has links)
In the field of sustainable manufacturing, a wide range of research has been carried out to attain the more effective use of natural resources and the reduction of environmental impacts during the whole product life cycle. This goal can be best achieved by promoting multiple-reuse of parts, sub-assemblies, or entire products. However, the decision toward reusing an old product depends on a variety of parameters with many uncertainties. Therefore, a comprehensive model to assess the reusability of products prior to the reuse decision is urgently needed. The objective of this research has been to develop a comprehensive assessment model, integrating technical, environmental, social, and economic aspects to evaluate the reusability of industrial products. The assessment model consists of four sub-models, which are a methodology to assess the quality and reliability of products, a model to translate the social responsibility aspect into warranty cost, a methodology to integrate environmental costs, and an economic model to accumulate total life cycle cost as the basis of the evaluation. The model also facilitates trade-offs between the factors to investigate the possibility to improve the reusability of a product. To apply the assessment model in the real business environment, a set of decisionmaking methodologies under different take-back scenarios has been developed as a guideline for manufacturers. Furthermore, as the existence of uncertainty in the reuse strategy is undeniable, a methodology to integrate uncertainties into the assessment model is also developed. The model validation, using three real cases collected from industrial partners on consumer and commercial products, has confirmed the applicability of the model to provide a useful tool to evaluate products at the end of their life cycle. The model also enables decision makers to disclose the risk associated with the decision, thus improving the quality of the decision. The results are in good agreement with the basic theory that the reuse and remanufacturing strategy is highly recommended from both environmental and economic reasons.

The Restoration of Israel: Ezekiel 36-39 in Early Jewish Interpretation: A textual-comparative study of the oldest extant Hebrew and Greek manuscripts.

Ashley@harvestwest.edu.au, Ashley Stewart Crane January 2006 (has links)
While many have noted the differences between the Hebrew and Greek manuscripts for Ezekiel, they have done so largely to rediscover an earlier Hebrew text, or to determine which variant preserves the better reading, frequently with the aim of establishing a ‘critical text’ for their commentaries. This often leaves the other variant(s) in a sense ‘incorrect’, often attributed to various forms of scribal error. This thesis adopts a ‘textual-comparative’ methodology that accords each textual witness equal status as an interpretive trajectory, enabling each to be ‘heard’ in its own right. The aim of this thesis is to examine these different witnesses with a view to determine what they might tell us about the way Ezekiel 36-39 was interpreted by each particular community. This entails comparing the oldest extant Hebrew and Greek texts both intra-linguistically and trans-linguistically, noting any variants, and exploring possible interpretive reasons for them. This study finds that the Greek translators were familiar with both languages, and that they often exegetically and interpretively interacted with the text before them. The Greek (LXX) is both translation and interpretation of the Hebrew. Other interpretations are found in ‘inserts’ or ‘plusses’, occurring in both the Hebrew and Greek texts. Included is an examination of Papyrus 967 (G967), which exhibits a different chapter order (chapter 37 follows 38-39), and is minus 36:23c-38. Rather than finding that these differences result from error, or that G967 is a maverick text, we find that it is closest to what was probably the Hebrew Urtext. All other extant Hebrew and Greek texts then exhibit theological interaction; the change of chapter order exhibiting a ‘call to arms’, and the inserted pericope (36:23c-38) exhibiting a ‘call to purity’. Our research methodology thus elucidates the earliest Jewish interpretation of the Restoration of Israel in Ezekiel 36-39 (ca. 200-50 BCE).
