Architectural effect on the surface tension of an ABA triblock copolymer melt

The excess surface energy of lamellae formed by an ABA triblock copolymer melt oriented parallel to a neutral surface is evaluated using self-consistent field theory (SCFT). Consistent with experiments and previous SCFT calculations, we find a preference for the A-rich domains at the surface, which can only be attributed to the architectural asymmetry between the A and B blocks. The behavior was previously attributed to a loss of bridging configurations that occurs when the B-domain resides at the surface. Here we demonstrate that it is actually the presence of chain ends that reduces the excess surface energy of an A-rich domain relative that of a B-rich domain.

Investigation of support vector machine for the detection of architectural distortion in mammographic images

This paper investigates detection of architectural distortion in mammographic images using support vector machine. Hausdorff dimension is used to characterise the texture feature of mammographic images. Support vector machine, a learning machine based on statistical learning theory, is trained through supervised learning to detect architectural distortion. Compared to the Radial Basis Function neural networks, SVM produced more accurate classification results in distinguishing architectural distortion abnormality from normal breast parenchyma.

Architects and their clients : relationships analysis using habitus theory

The nature and quality of hte architect relationship is critical fror project success yet its managment remains problematic.  This interdisciplinary study draws theory from sociology to further our understanding of this built environment industry problem.  The concept of habitus, developed by french sociologist Bourdieu, helps to demystify the architect-client relationship and explain the underlaying cause of conflicts between architects and clients.  Habitus theory explains that the nature of architecture as a specialised activity places architects within an architectural habitus, distinguishing architects from clients who are not trained as professional architects.

Between theory and practice : Rudolf Steiner as philosopher and architect

The philosophy and architecture of Rudolf Steiner both aim to give formal expression to his esoteric worldview, however, the means of articulating this worldview fundamentally differ within each discipline. Philosophy and architecture are separated by both process and product, and while an interdisciplinary reading of Steiner’s work does make certain connections between them evident, the incorporeal nature of thinking and the physical reality of building inevitably require different skills of their author, as well as different standards by which to assess them. Although he had no formal training as an architect, Steiner believed that his system of Anthroposophy provided a conceptual framework that would inspire a new style of modern architecture imbued with a spiritual dimension. As such, architecture provided Steiner with a means of visually expressing what words could not, and was therefore a necessary and important part of his philosophical pursuit. This paper explores the tension that exists between Steiner’s philosophy and architecture in its translation from theoretical ideas into built form. Steiner’s approach to architectural design was less concerned with the methods and techniques of the craft than with achieving what he saw as architecture’s true purpose - namely to give voice to the inner spiritual content of the work. However, in order to achieve this ultimate goal, a certain level of architectural competence is required. Therefore, Steiner’s ability as an architect to articulate such lofty ideals will also be assessed. Conceived on the edge of theory and practice, Steiner’s work serves to demonstrate the richness and depth that such an approach has to offer the field of architecture.

Indigenous landscape change and climate change : the historical transformation of the Port Phillip bay from an indigenous and landscape architectural perspective

Currently there is a dearth of research into Australian Indigenous knowledge and their understanding of climate change especially in regard to how it fits into an Indigenous world view. Recent discussions by the National Climate Change Adaptation Research Facility (NCCARF) have highlighted this deficiency and also the need to source projects that address this perspective, and enable the incorporation of traditional ecological knowledge into the planning of climate change adaption strategies. Within this context, this paper examines the use and understanding of landscape, both urban and regional, surrounding Port Phillip Bay and the risks and opportunities climate change adaptation brings to the local Indigenous communities. This paper comprises a literature review and proposes further research with the Wurundjeri (Yarra Valley), Wathaurong (Geelong-Bellarine Peninsula) & Boon Wurrung (Mornington Peninsula - Westerport - southern Melbourne) which aim to elicit a contemporary and local response to issues raised by NCCARF but importantly to articulate a possible Indigenous position about the formation, change and direction that Port Phillip Bay and its environs should take from their perspectives. The research looks to draw on how these communities have adapted to climate change physically, mentally and spiritually over their long habitation of the region and their perceptions of climate change this century. The project looks to uncover a longitudinal perspective of adaptation focused upon Indigenous views of 'country' and custodial obligations to 'country' including accumulated cultural and environmental histories, and how this can inform the contemporary practice of landscape architecture and the design of resilient and sustainable human environments.

Internationalization to China: a model for Australian architectural, engineering and construction firms

The experiences of an architectural, an engineering, and a construction organization, when internationalizing to China, are compared to extant theories of internationalization to develop an enhanced explanation if these organizations’ internationalization. The research examines the explanatory power of both the Uppsala internationalization model and network theory for internationalization. The research determined that, whilst these organizations utilized an incremental internationalization process, the stages differed from those identified in the Uppsala model. Part of this difference reflects the fact that the participants are service organizations and the Uppsala model is more relevant to manufacturing organizations. Network theory was also found to predict some of the participant behaviors; however, it did not correctly predict the reasons for forming partnerships, which was to gain knowledge rather than develop networks. The stages of the internationalization into China identified were: (1) experiencing a motivation to internationalize; (2) adopting one of a variety of entry modes; (3) experiencing a motivation to increase internationalization to the level of a wholly-owned foreign entity; (4) establishment of a wholly-owned foreign entity (WOFE), either by acquisition or development; and (5) further horizontal expansion (such as movement to new locations). A range of different motivations for both stages one and three were identified.

An issues paper: the roots/routes of Australian architecture: elements of an alternative architectural history

The dynamism and mobility of architects in their approach to architecturaldesign practice provides a context that emphasises that architecture, likeculture, is not static or rooted in place, but is intricately configured throughthe dual processes of locality and mobility – both physical and theoretical. Theproduction of architecture in Australia, as in other immigrant-rich societies,provides a case for reinforcing the theory that architectural mobility and travelare integral to the architecture of place.This issues paper sets out to re-examine the contribution of geo-culturalinfluences upon Australia’s architectural lineage and considers a diverse rangeof themes across an equally broad timeframe; British colonial transpositions; thedissemination of Modernism in Australia; the latent contribution of mid-twentiethcentury European émigré architects; and the secreted history of Australia’sAsian architecture. Common to all, however, is the notion of architecturaltranslation as a process of influences transmitted, transposed or adapted toother contexts. It uses Australia as the focus from which to consider how globalcriticism, ideas and theories have travelled and continue to travel transverselyacross time and place, from the late-eighteenth century well into the twenty-first.This paper investigates translations through narratives, processes, networks andtraces of architectural manifestations and begins to draw lines of influence.

Fractal dimension and Shannon's entropy analyses of the architectural complexity caused by the inflammatory reactions induced by highly crystalline polyvinyl alcohol) microspheres implanted in subcutaneous tissues of the Wistar rats

The results of the histopathological analyses after the implantation of highly crystalline PVA microspheres in subcutaneous tissues of Wistar rats are here in reported. Three different groups of PVA microparticles were systematically studied: highly crystalline, amorphous, and commercial ones. In addition to these experiments, complementary analyses of architectural complexity were performed using fractal dimension (FD), and Shannon's entropy (SE) concepts. The highly crystalline microspheres induced inflammatory reactions similar to the ones observed for the commercial ones, while the inflammatory reactions caused by the amorphous ones were less intense. Statistical analyses of the subcutaneous tissues of Wistar rats implanted with the highly crystalline microspheres resulted in FD and SE values significantly higher than the statistical parameters observed for the amorphous ones. The FD and SE parameters obtained for the subcutaneous tissues of Wistar rats implanted with crystalline and commercial microparticles were statistically similar. Briefly, the results indicated that the new highly crystalline microspheres had biocompatible behavior comparable to the commercial ones. In addition, statistical tools such as FD and SE analyses when combined with histopathological analyses can be useful tools to investigate the architectural complexity tissues caused by complex inflammatory reactions. © 2012 WILEY PERIODICALS, INC.

Training organization of a middle-size company engaged in information technology services: theory and practice

In order to establish an active internal know-how -reserve~ in an information processing and engineering services . company, a training architecture tailored to the company as an whole must be defined. When a company' s earnings come from . advisory services dynamically structured i.n the form of projects, as is the case at hand, difficulties arise that must be taken into account in the architectural design. The first difficulties are of a psychological nature and the design method proposed here begjns wi th the definition of the highest training metasystem, which is aimed at making adjustments for the variety of perceptions of the company's human components, before the architecture can be designed. This approach may be considered as an application of the cybernetic Law of Requisita Variety (Ashby) and of the Principle of Conceptual Integrity (Brooks) . Also included is a description of sorne of the results of the first steps of metasystems at the level of company organization.

Nuclear Architecture: Perceptions of Architectural Technology

In this paper we explore the implications of pluralist curricula for architectural technology. This includes the potential effects on strengthening the identity of the architectural technology profession and the academic development of the discipline. This latter relies, arguably, on research being explicit in CIAT’s eight mandatory threshold standards. This work concentrates on one of the Chartered Institute of Architectural Technologist’s (CIATS’s) key subjects; 'design', defined as detail design for the architectural technologist. In postulating a philosophy of architectural technology epistemology with a focus on detail design, the pedagogy of architectural detailing in practice and academia is investigated: the associated roles of creativity and conditioning are explored. The interrelationship between conceptual design and construction processes in practice is outlined, identifying the role of the detail design specialist (architectural technologist) in the management of design and production information. Thus is identified the future architectural technologists’ specialisation of nuclear architecture: the total quality construction created by quality of thinking which permeates from and to detail design for assembly/disassembly and production within a collaboratively mechanised AEC team. A theory of nuclear architecture and an associated approach to detail design pedagogy are postulated, aiming to promote a revised perception of the definition of design for the architectural technologist. How this theory can be applied to the creation of a paradigmatic student project, themed on designing for disassembly as a key future focus of ‘Healthy Building’ design is introduced for future exploration. This future research into detail design, the authors propose, should be predicated on the appropriate methodology related to the epistemology of a design-based area of the architectural technology discipline. The roles of Professional, Statutory and Regulatory Bodies (PSRB) in the evaluation and subsequent dissemination of this detail design pedagogy, with the aim of strengthening the architectural technology discipline are emphasised.

Problem solving in architectural design

This thesis is presented in two parts. The first part is an attempt to set out a framework of factors influencing the problem solving stage of the architectural design process. The discussion covers the nature of architectural problems and some of the main ways in which they differ from other types of design problems. The structure of constraints that both the problem and the architect impose upon solutions are seen as of great importance in defining the type of design problem solving situation. The problem solver, or architect, is then studied. The literature of the psychology of thinking is surveyed for relevant work . All of the traditional schools of psychology are found wanting in terms of providing a comprehensive theory of thinking. Various types of thinking are examined, particularly structural and productive thought, for their relevance to design problem solving. Finally some reported common traits of architects are briefly reviewed. The second section is a report of u~o main experiments which model some aspects of architectural design problem solving. The first experiment examines the way in which architects come to understand the structure of their problems. The performances of first and final year architectural students are compared with those of postgraduate science students and sixth form pupils. On the whole these groups show significantly different results and also different cognitive strategies. The second experiment poses design problems which involve both subjective and objective criteria, and examines the way in which final year architectural students are able to relate the different types of constraint produced. In the final section the significance of all the results is suggested. Some educational and methodological implications are discussed and some further experiments and investigations are proposed.

Formal verification and testing of software architectural models

Ensuring the correctness of software has been the major motivation in software research, constituting a Grand Challenge. Due to its impact in the final implementation, one critical aspect of software is its architectural design. By guaranteeing a correct architectural design, major and costly flaws can be caught early on in the development cycle. Software architecture design has received a lot of attention in the past years, with several methods, techniques and tools developed. However, there is still more to be done, such as providing adequate formal analysis of software architectures. On these regards, a framework to ensure system dependability from design to implementation has been developed at FIU (Florida International University). This framework is based on SAM (Software Architecture Model), an ADL (Architecture Description Language), that allows hierarchical compositions of components and connectors, defines an architectural modeling language for the behavior of components and connectors, and provides a specification language for the behavioral properties. The behavioral model of a SAM model is expressed in the form of Petri nets and the properties in first order linear temporal logic.^ This dissertation presents a formal verification and testing approach to guarantee the correctness of Software Architectures. The Software Architectures studied are expressed in SAM. For the formal verification approach, the technique applied was model checking and the model checker of choice was Spin. As part of the approach, a SAM model is formally translated to a model in the input language of Spin and verified for its correctness with respect to temporal properties. In terms of testing, a testing approach for SAM architectures was defined which includes the evaluation of test cases based on Petri net testing theory to be used in the testing process at the design level. Additionally, the information at the design level is used to derive test cases for the implementation level. Finally, a modeling and analysis tool (SAM tool) was implemented to help support the design and analysis of SAM models. The results show the applicability of the approach to testing and verification of SAM models with the aid of the SAM tool.^
