Spherical harmonics and distance transform for image representation and retrieval

In this paper, we have proposed a method for 2D image retrieval based on object shapes. The method relies on transforming the 2D images into 3D space based on distance transform. Spherical harmonics are obtained for the 3D data and used as descriptors for the underlying 2D images. The proposed method is compared against two existing methods which use spherical harmonics for shape based retrieval of images. MPEG-7 Still Images Content Set is used for performing experiments; this dataset consists of 3621 still images. Experimental results show that the performance of the proposed descriptors is significantly better than other methods in the same category.

Computing the numerical scale of the linguistic term set for the 2-tuple fuzzy linguistic representation model

When using linguistic approaches to solve decision problems, we need the techniques for computing with words (CW). Together with the 2-tuple fuzzy linguistic representation models (i.e., the Herrera and Mart´ınez model and the Wang and Hao model), some computational techniques for CW are also developed. In this paper, we define the concept of numerical scale and extend the 2-tuple fuzzy linguistic representation models under the numerical scale.We find that the key of computational techniques
based on linguistic 2-tuples is to set suitable numerical scale with
the purpose of making transformations between linguistic 2-tuples
and numerical values. By defining the concept of the transitive
calibration matrix and its consistent index, this paper develops an optimization model to compute the numerical scale of the linguistic term set. The desired properties of the optimization model are also presented. Furthermore, we discuss how to construct the transitive calibration matrix for decision problems using linguistic preference relations and analyze the linkage between the consistent index of the transitive calibration matrix and one of the linguistic preference relations. The results in this paper are pretty helpful to complete the fuzzy 2-tuple representation models for CW.

Impact of context and representation on year 10 students' expression of conceptions of rate

Rate is an important, but difficult mathematical concept. More than twenty years of research, especially with calculus students, report difficulties with this concept. This paper reports on an alternative analysis, from the perspective of multiple representations and context, of interviews probing twenty Victorian Year 10 students’ conceptions of rate. This analysis shows that multiple representations of functions provide different rate-related
information for different students. Understandings of rate in one representation or context are not necessarily transferred to another representation or context.

Will these glasses help? Holocaust videotestimony and the transfer of intangible heritage

An analysis of Erica's videotestimony, presented at the Jewish Holocaust Museum and Research Centre in Melbourne, reveals how audio-visual history can act as a medium for the transfer of cultural heritage, despite claims that the trauma of the Holocaust has destroyed the possibility of any meaningful transmissíon. It is argued that the discussion of personal photographs from before and after the Holocaust forms a key component of the videotestimony and constitutes the primary mechanism for intergenerational transfer of Jewish communal heritage, Transfer is further facilitated by the interviewer whose questioning explicitly encourages Erica to reflect on issues of cultural continuity. Significantly, Erica's answers do not always conform to the interviewer's expectations about Jewish communal and religious identification and this can result in tension between the
two. Here too the photographs play an important role in resolving tension between Erica and the interviewer.

Reading indigeneity : the ethics of interpretation and representation

The transmission of indigenous stories is a fraught enterprise. In contrast to Western practices of the free circulation of ideas, many indigenous cultures view their stories as sacred, and have strict rules about who may tell certain tales, and in what settings and with whom they may be shared. Indigenous storytellers and novelists who want to tell contemporary stories also face the minefields of a history of (mis)representation of their cultures' values and practices. Australian literary scholar Clare Bradford picks her way carefully through this minefield, identifying its perils and proposing a self-reflexive practice that enables scholars to approach these works with sensitivity; Abenaki children's author Joseph Bruchac adds his own impressions and frustrations as an author to Clare's frank assessment of the possibilities of criticism, cross-talk, and mutual understanding in the fìeld.

Negotiating memory and identity : the Hyde Park Holocaust Memorial, London

In 1983, 38 years after the end of World War II, Britain gained its first public memorial dedicated solely to victims of the Holocaust: the Hyde Park Holocaust Memorial Garden. Organized by the Board of Deputies of British Jews, this campaign revealed the ways that memorialization of the Holocaust in Britain during the 1980s was cross cut with issues of identity, memory and history. In attempting to restore the «biography» of the memorial, this paper examines the way the memorial's relationship with its potential locations is important in the making of meaning and shows how debates over the perceived appropriateness of the sites were structured by, and in turn structure, various discourses concerning Anglo-Jewish identity.

On representation and construction in a tectonic design studio

This study investigates the roles of representationand construction in enhancing students' learning in a tectonic design studio.  Students of architecture use 3D CAD, physical models and drawings, either alone or in hybrid combinations in the the design, development and communication of their design process.  Each of these media has intrinsic attributes that limit or enhance students' ability to engage in issues of architecture.  This can have a significant influence on students' learning of conceptual and tectonic design, in particularly in their early years of study.  Tectonic design, as an element of the architectural design process that involves the designerly consideration of issues of construction, is an important skill that is integral to architectural practice.  The unique problem based learning environment of the design studio offers opportunities for the development of deep learning approaches to tectonic design, however these are limited by the way students engage in representational media.  This research is based on an ethnographis case study of a cohort of second year architecture students at Deakin University, Geelong, in 2002.

Inclusive schooling : representation and textual practice

This paper reports on a larger study carried out in the island state of Tasmania, Australia, between 1996 and 1998. The research reviewed the impact of the Inclusion of Students with Disabilities Policy (ISDP) within the government school system. The qualitative study describes the interpretations of five key informants: a parent; two teachers—a support teacher and a class teacher—a policy-maker and a university academic, during the early period of the implementation of the ISDP. The visual and literary ‘data stories’ of the research are woven together to narrate inclusive schooling in the Tasmanian context as a ‘detective story’ of the special education knowledge tradition. Drawing from poststructuralist methodology and narrative theory the multi-voiced text is a deliberate attempt to enter into conversations with the reader rather than tell the story. Researching inclusive schooling policy through representation and textual practice, I question dominant research practices in the special education field and populist slogans of ‘inclusion’.

Representation of female offender types within the pathways model of assault

Research into the heterogeneity of female violent offending is sparse, even though females constitute a growing part of the prisoner population. There is evidence that the majority of female violent offenders display over-controlled traits related to uncharacteristic offending. This hypothesis was explored through a multivariate model, the Pathways Model of Assault, with interview data from 17 female assault offenders. Five different offence types were displayed, reflecting the same offence styles as male offenders. However, only two participants displayed an over-controlled offence type. Qualitative differences within the data suggested that offender rehabilitation should be tailored specifically for different gender needs in addition to the needs suggested by the different offence types.

Subjective wellbeing in Australian families of Holocaust survivors

This thesis explored the idea that trauma experienced by Holocaust survivors has been transferred to their children and grandchildren. Findings provided evidence for an ' intergenerational transmission of trauma, revealing children of two Holocaust survivors to be particularly at risk. The transmission oftrauma was best explained through an attachment model.

A method for the visual representation of historic multivariate point data

The visual representation of multivariate spatial and temporal data is important for interpreting and analyzing historical geographic patterns that change over time. The introduction of geospatial technologies in historical scholarship has challenged the suitability of current visual representations due to the need for greater temporal emphasis and the tracking of historical events over time. This research presents a holistic multivariate approach to historical visual representation for point based historical data. The method has been developed through extending the spatial presence in information graphics and through meaningful spatial classification. This paper demonstrates the benefits gained from integrating historical, geographic, temporal, and attribute data through the development of a case study on the history of Melbourne’s cinema venues between 1946 and 1986.
