Material properties under drawing and extrusion with cyclic torsion

A copper bar was drawn while a lead bar was extruded through a cyclically twisting die in a specifically designed experimental rig. The drawing/extrusion load fluctuated at the same frequency as that of die twisting. The load tended to be at a level of monotonic deformation when the die was changing direction. The degree of the reduction in load for both the drawing and extrusion processes depended on the deformation conditions and requires optimisation for industrial application.

Interaction between the coating characteristics of galvanneal steel and forming parameters during flat die drawing

Galvanneal steel is considered to be better for automotive applications than its counterpart, galvanized steel, mainly because of its superior coating and surface properties. Galvanneal steel is produced by hot dipping sheet steel in a bath of molten zinc with small, controlled, levels of aluminium, followed by annealing which creates a Fe-Zn intermetallic layer. This intermetallic layer of the coating improves spot weldability and improves subsequent paint appearance. However, if the microstructure of the coating is not properly controlled and forming parameters are not properly selected, wear of the coating could occur during stamping. Frictional sliding of the sheet between the tool surfaces results in considerable amount of coating loss. An Interstitial Free steel with a Galvanneal coating of nominally 60g/m2 was used for the laboratory experiments. Flat Face Friction (FFF) tests were performed with different forming conditions and lubricants to simulate the frictional sliding in stamping. Glow-Discharge Optical Emission Spectrometry (DG-OES) was used to measure the change in the coating thickness during sliding. Optical microscopy was considered for imaging the surfaces as well as an optical method to compare the changes in the coating thickness during the forming. The change to the Galvanneal coating thickness was found to be a function of forming parameters.

Selection, exclusion and assimilation: the project lambert of 1931 on the reform of French immigration policy

The unemployment crisis of 1926-7 focused attention onto the question of immigration. Historians of this period have generally focused on the crisis of public policy and popular antipathies towards foreigners; more recently historians have become attuned to voices of racism. Less attention has been paid to attempts to redress the policy weaknesses through a new legislative regime on immigration. This paper reviews one such proposal, made by Charles Lambert, a deputy from the Rhone, in 1931. Instrumental in a revision of the naturalization law in 1927 to encourage the assimilation of foreigners through the acquisition of French citizenship, Lambert proposed a comprehensive statute on immigration to select “desirable” foreigners and exclude the “undesirables” to promote the assimilation of the “better” elements. The paper argues that his rationale betrays a profound fear of mounting French weakness in the face of economic and demographic decline, and grave anxieties for the future health of the French nation.

Of personalities and personae: a French victory for film producers and authors

The international medium of film poses many challenges for authors and copyright owners. So do the practices of the advertising industry. Each jurisdiction approaches these challenges differently. In a recent French decision three issues that are of interest in Australia were discussed – the copyright status of a literary or dramatic character, the use of such a persona in character merchandising, and the moral right of film directors to control the exploitation of the persona. This article examines the 2004 decision of the Paris Court of Appeal in the matter of the film “The Fifth Element”. It compares the protection offered to author and copyright owner under French law with the protection offered by Australian legislation and common law.

A general rooted tree drawing algorithm

A general rooted tree drawing algorithm is designed in this paper. It satisfies the basic aesthetic criteria and can be well applied to binary trees. Given an area, any complex tree can be drawn within the area in users' favorite styles. The algorithm is efficient with O(LxNxlogN) time complexity and self-adaptive as well.

Cross-discipline collaboration and innovation in the design studio : drawing on the Bath model

As information expands and comprehension becomes more complex, so the need increases to develop focused areas of knowledge and skill acquisition. However, as the number of specialty areas increases so the languages that define each separate knowledge base become increasingly remote. Hence, concepts and viewpoints that were once considered part of a whole become detached. This phenomenon is typical of the development of tertiary education, especially within professional oriented courses, where disciplines and sub-disciplines have grown further apart and the ability to communicate has become increasingly fragmented.
One individual and visionary who was well acquainted with the shortcomings of the piecemeal development between the disciplines was Professor Sir Edmond Happold, the leader of the prestigious group known as Structures 3 at Ove Arup and Partners, who were responsible for making happen some of the landmark buildings of their time, including Sydney Opera House and the Pompidou Centre, and the founding professor of the Bath school of Architecture and Civil Engineering in 1975. While still having a profound respect for the knowledge bases of the different professions within the building and construction industry, Professor Happold was also well aware of the extraordinary synergies in design and innovation which could come about when the disciplines of Architecture and Civil Engineering were brought together at the outset of the design process.
This paper discusses the rational behind Professor Happold’s cross-discipline model of education and reflects on the method, execution and pedagogical worth of the joint studio-based projects which formed a core aspect of the third year program at the School of Architecture and Civil Engineering at the Bath University.

Drawing and the subjectivity of the 'other'

Scenes of the Aboriginal family sitting around a table in the film The Fringe Dwellers present the boy quietly drawing, while other members of the family are engaged in discussion. The boy is less visible, more passive and contemplative, and his subjectivity is suggested rather than explored in the film. He repeats the same activity and the same inward concentration. My hypothesis is that the boy's subjectivity and agency are projected elsewhere, towards an imaginary field beyond the film's structure and beyond the social reality of the film's outside. What is the aboriginal boy drawing? In one scene, is a glimpse of his 'projection', he draws a house. The boy is mesmerised and pre-occupied by his drawing. We have seen the mystery of this preoccupation in images of heroic modernist architects (Le Corbusier, Frank Lloyd Wright, Oscar Niemeyer come to mind) presenting a connection between the hand of the architect and his sketch as an essential gift in the making of a 'master architect'. Through this visual association, the 'Aboriginal boy drawing' is associated with the field of 'a universal human subject' and the essay investigates how his practice might participate in new subjective positions across disciplines. Through his inscriptions, the Aboriginal boy expresses more than a wish: he articulates and inhabits another dwelling, an imaginary dwelling of a subjectivity and 'identity' beyond the black and white divide. The boy, however, is not a 'master', making his drawing a subversive and risky practice.

The design studio: fabricating a sense of architecture in drawing

The purpose of this paper is to provide a platform for investigating the relationship between the student and the tutor via the design drawing and in particular the idea that what gives grounds for architecture to embody something is what is imagined is expressed in the design drawing. It is suggested that in architectural education the sense of architecture's fabricated properties find their apparent expression from the convergence of the tutor and student toward these drawings. In an act of perceptual contortion, there is an endeavour to reconcile what they see with what they think the drawing might suggest. Part of this mental reconstruction is based on the expectation that something is in the drawing to see. The drawing is produced based on the supposition that it will be read, generating a particular conditioning of the student's attitude toward the relevance of the drawing. It is engaged as the receptacle of ideas about what architecture is. The result is that sometimes the emphasis on the drawing as something to be consumed implies a permeation of the supposed sensory qualities of architecture imagined by the student designer, the portrayal of which is indubitably a product of the medium. While this might be commonly experienced in studios, it is proposed that this may be perpetuated in architectural education not merely by the act of drawing itself and what the drawing is, but how the student/tutor exchange contributes to the consciousness of what is portrayed.

Human resource practices, unionization and the organizational efficiency of French industry

Organizational performance improves through several channels, including changes in efficiency, innovation and technological change. Most of the extant research has focused on overall performance, often measured by partial measures of productivity, with little attention given to the components of performance. The aim of this paper is to analyze the impact of HR practices and unionization on one important channel - organization efficiency - as measured by technical and scale efficiency. Using French industry survey data, the paper shows that HR practices do influence efficiency, but this is moderated by the existence of unions. The results show a rather complex set of associations. We find robust results that show that in France, HR practices have a positive effect on scale efficiency but this effect is dampened in the presence of unions. On their own, HRpractices have no effect on technical efficiency. However, some of the results suggest that HR practices can exert a positive influence when combined with unions.

Exchange rate exposure, foreign currency derivatives and the introduction of the euro: French evidence

We investigate the impact of the introduction of the Euro on exchange rate exposures for French corporations and examine the corporate use of foreign currency derivatives to hedge exchange rate exposure post-Euro. Our findings indicate that the introduction of the Euro is associated with both a reduction in the number of firms that have significant exchange rate exposure and the absolute size of exposure. Consistent with these reduced exposures, French firms use foreign currency derivatives less intensively. Furthermore, the use of foreign currency derivatives is found to be associated with lower exchange rate exposure but there is insufficient evidence that these instruments are more effective in the post-Euro environment.
