Automated Methods for Virtual Maintainability & Aerospace Maintenance Planning

Abstract. Modern business practices in engineering are increasingly turning to post manufacture service provision in an attempt to generate additional revenue streams and ensure commercial sustainability. Maintainability has always been a consideration during the design process but in the past it has been generally considered to be of tertiary importance behind manufacturability and primary product function in terms of design priorities. The need to draw whole life considerations into concurrent engineering (CE) practice has encouraged companies to address issues such as maintenance, earlier in the design process giving equal importance to all aspects of the product lifecycle. The consideration of design for maintainability (DFM) early in the design process has the potential to significantly reduce maintenance costs, and improve overall running efficiencies as well as safety levels. However a lack of simulation tools still hinders the adaptation of CE to include practical elements of design and therefore further research is required to develop methods by which ‘hands on’ activities such as maintenance can be fully assessed and optimised as concepts develop. Virtual Reality (VR) has the potential to address this issue but the application of these traditionally high cost systems can require complex infrastructure and their use has typically focused on aesthetic aspects of mature designs. This paper examines the application of cost effective VR technology to the rapid assessment of aircraft interior inspection during conceptual design. It focuses on the integration of VR hardware with a typical desktop engineering system and examines the challenges with data transfer, graphics quality and the development of practical user functions within the VR environment. Conclusions drawn to date indicate that the system has the potential to improve maintenance planning through the provision of a usable environment for inspection which is available as soon as preliminary structural models are generated as part of the conceptual design process. Challenges still exist in the efficient transfer of data between the CAD and VR environments as well as the quantification of any benefits that result from the proposed approach. The result of this research will help to improve product maintainability, reduce product development cycle times and lower maintenance costs.

Starbog: The Garden Virtuoso and the Turing Machine

This article will discuss a recent ensemble composition entitled Starbog which was toured and broadcast in Britain in 2006 . The composition of Starbog focused on developing working methods which combined computer-based techniques (using OpenMusic) with more subconscious means of generating musical ideas. The challenge in achieving this was as much aesthetic/philosophical as it was technical and the present article is intending as a ‘sounding’ which focuses on the influence OpenMusic has had on the composer’s music, rather than documenting the nature of the often simple application of algorithms.

Reflecting on Psycho-Social Domains in Social Work: Towards a Model of Enabling Others (Monograph Version with ISBN)

This monograph develops a model of reflexivity for social workers based on the work of Derek Layder. It examines psycho-biographical, interactional, institutional, cultural and economic factors and how they enable and constrain social work practice.

‘A dance for all the outcasts’: Class and Postcolonialism in Brendan Behan’s An Giall and The Hostage

As Susan Bassnett and Harish Trivedi argue, ‘translation does not happen in a vacuum, but in a continuum; it is not an isolated act, it is part of an ongoing process of intercultural transfer’. In understanding Brendan Behan's most celebrated and controversial translation, of his spare Irish language play An Giall (1958) to its riotous English counterpart The Hostage (1958), understanding the problematic ‘intercultural transfer’ between British and Irish life in the 1950s is crucial. Comparisons between both works reveal significant changes that illuminate Behan's relationship with both nations and provide a sometimes oblique metacommentary regarding his most pressing political and personal anxieties. Yet for all their differences, the plays also share a common desire to transcend the divisions forged by the colonial experience through critical understandings of life on either side of the Irish Sea. In this essay, I argue that Behan's act of transculturation reveals a great deal more reflexivity and depth than many of his critics would allow, developing an iconoclastic dialogue between British and Irish mid-century life.

The Potency of Pastoral in Hispanic Baroque poetry

This monograph demonstrates that aesthetic and ontological anxieties continue to find diverse expression within the contrived textual artifice of the bucolic space. Drawing upon expansive definitions of the Hispanic literary Baroque, (Beverley, 1980, 2008, Echevarría 1993, Ross 1993, Chemris 2008 , Egido 2009 ) the study analyses the pastoral verse of representative poets of the period to demonstrate that they re-enter an Arcadia that has been defamiliarized but is nonetheless inexorably connected to the classical origins of the mode. Pastoral, in common with other literary forms, is subject to a process of re-evaluation which was latent in its classical legacy. Within the intricacies of this literary construct, surface artistry sustains an effect of artless innocence that is vibrantly contested across the secular, sacred, parodic and colonial text.

Performer as perceiver: perceiver as performer

The proposition in the title of this paper is intended to draw a link between psychological processes involved in aesthetic gestural performance (e.g. music, dance) for both performers and perceivers. In the performance scenario, the player/dancer/etc., perceptually guides their actions, and acquires the skill for a performance through their previous perceptions. On the other side, the perceiver watching, listening to and experiencing another’s motor performance, simulates the actions of the performance within the range of their own motor capabilities. These phenomena are possible due to common mechanisms of action and perception, and in tandem provide the basis for the rich experience of gestural performance.
This paper reviews evidence for these claims, using examples from the domains of music and dance performance. Questions that arise from these propositions are addressed and suggested empirical explorations of these ideas are given. Further problems in incorporating these theories about gestural performance experience within Enaction are highlighted for future discussion.

Skin-reducing mastectomy and one-stage implant reconstruction with a myodermal flap: A safe and effective technique in risk-reducing and therapeutic mastectomy

Introduction: Immediate reconstruction following mastectomy for breast cancer has been shown to be oncologically safe and associated with improved psychosocial outcomes for patients. Bostwick described a technique for one-stage implant based reconstruction, combining skin-sparing mastectomy with concurrent reduction of the skin envelope. This report reviews the experience of a single centre using skin-reducing mastectomy and one-stage implant reconstruction in both early stage breast cancer and risk-reducing mastectomy, with specific reference to frequency of complications, implant loss and oncological outcomes.

Methods and results: A retrospective review was undertaken to identify women who had undergone skin-reducing mastectomy and one-stage implant reconstruction using a de-epithelialised dermal flap, between October 2008 and October 2012. One hundred and four consecutive mastectomies, with reconstruction, were performed by two surgeons on 64 patients. No complications were seen in 43.8% of patients. At three months, four implants were lost (3.8% of breast reconstructions, 6.3% of patients), due to either peri-implant infection or mastectomy skin flap necrosis. One patient required unplanned return to theatre for evacuation of a haematoma. Minor mastectomy skin flap necrosis was seen in 10 breasts (9.6% of reconstructed breasts) and superficial wound infection in 8 breasts (7.7% of reconstructed breasts). All of these complications were managed conservatively and none required operative intervention. At a median follow up of 35 months (4-53 months) there had been one episode of ipsilateral axillary nodal recurrence.

Conclusion: One-stage implant reconstruction using a myo-dermal flap technique following skin-reducing mastectomy is safe and should be considered in selected patients. Most complications are minor and will resolve with conservative management. Major complications such as implant failure or immediate reoperation, were relatively uncommon (6.3% patients, 3.8% of reconstructed breasts). Early follow-up suggests that oncological outcomes are satisfactory, but longer follow-up is required to substantiate this.

Augmentation mammoplasty: effect on diagnosis of breast cancer

Breast augmentation for cosmetic purposes is an increasingly common procedure in the USA and UK. In the USA in 2003, a total of 254 140 breast augmentation procedures were carried out [American Society of Plastic Surgeons, http://www.plasticsurgery.org/newsroom/ Procedural-Statistics-Press-Kit-Index.cfm9-1-2005; 2006.(1)]. It has been previously estimated that between 1 and 1.5 million women in the USA have prosthetic breast implants [Cook RR, Delongchamp RR, Woodbury M, et at. The prevalence of women with breast implants in the United States, 1989. J Clin Epidemiol 1995;48:519-25.(2)]. The UK National Breast Implant Registry has recorded a rise in the numbers of women receiving breast implants, with over 13 000 procedures registered in 2001; an estimated 77% of these were for cosmetic purposes. No association has been found between the presence of breast implants in a breast and an increased risk of breast cancer, and this subject has been comprehensively reviewed elsewhere [Hoshaw SJ, Klein PJ, Clark BD, et al. Breast implants and cancer: causation, delayed detection, and survival. Plast Reconstr Surg 2001; 107:1393-407.(3)]. However, as the population of women with breast implants ages, an increasing number of them will develop breast cancer; a reflection of the fact that the incidence of the disease increases with increasing age. Debate continues on the effect of breast implants on the efficacy of mammography in diagnosing breast cancer, and the role of other imaging techniques for this purpose, as well as the limitations that the presence of implants place on percutaneous biopsy techniques. We review the Literature on the radiological and tissue diagnosis of breast cancer in women with a history of previous augmentation mammaplasty.

Breast cancer following augmentation mammoplasty - a review of its impact on prognosis and management

The incidence of breast cancer in women with implants is increasing and will continue to do so for the foreseeable future due to the marked increase in breast implant insertion in recent years. Undoubtedly many of these women will wish to know whether the presence of implants worsens the prognosis of their breast cancer. Furthermore, the clinical management of such patients may be difficult, as aesthetic results are likely to be a major concern for women who have already undergone cosmetic surgery to the breast. There is no consensus on surgical approach to this scenario. This article reviews the literature on the prognosis of breast cancer patients with a history of augmentation mammoplasty and examines the available data regarding their surgical treatment.

Empowering Art: Reconfiguring narratives of trauma and hope in the Australian national imaginary

Aboriginal art has been the source of much contention between art curators, gallery owners, art critics and Aboriginal artists themselves. Early aesthetic debates about whether so-called traditional works should be considered ethnographic or artistic have led, at times, to conflicts over the rights of Aboriginal people to have their works exhibited according to the criteria applied to other kinds of Western artworks. This article explores how the dilemmas of troubled ethno-histories are critically embodied and reconfigured in texture and colour. It considers the problems that silenced histories pose for those responsible for their display to the public. As Aboriginal images often conceal troubled intercultural encounters it asks how artworks can be used to provide a counter-polemic to national rhetoric as artists seek to reshape and improve intergenerational futures. This text is published as a counterpart to the contribution to Disturbing Pasts from the artist Heather Kamarra Shearer.

Botulinum toxin A for the treatment of keloids

Keloids are the result of excessive scar tissue formation. Besides their poor aesthetic appearance, keloids can be associated with severe clinical symptoms such as pain, itching, and rigidity. Unfortunately, most therapeutic approaches remain clinically unsatisfactory. Recently, injections with botulinum toxin A (BTA) were proposed for the treatment of established keloids in a clinical trial. In this study, we aimed to verify the effects of intralesional BTA for the treatment of therapy-resistant keloids using objective measurements. In addition, the underlying molecular mechanisms were investigated using cultured keloid-derived fibroblasts.

An anatomical and analytical study of the Modiolus: Enlightening its relevance to plastic surgery

Background: This study was designed to evaluate the structures, muscles, and fasciae of which the modiolus is composed. It can aid in the understanding and, therefore, the utilization of plastic surgery for the aesthetic or reconstructive treatment of that region, especially the angle of the mouth. Methods: Dissections of the midface were done on five different cadavers. They were of different races (3 males, 2 females). The anatomy of the modiolus was studied in detail. New anatomical observations were classified as type I through type VI. Results: The perifacial artery fascia contributed to the modiolus in four (80%) specimens and was not part of it in 1 (20%) specimen. The facial artery was anterior to it in one (20%) specimen, lateral in four (80%) specimens, and never medial to it. No significant relationship was observed between the perifacial artery fascia contribution to the modiolus and gender or race. Also, the location of the facial artery lateral or anterior to the modiolus was not significantly related to gender or race. In addition, the deep and superficial fasciae of the face converged not anterior to the masseter muscle but actually at the modiolus, which was different from observations made by others. Conclusion: The modiolus is of critical importance in aesthetic and reconstructive plastic surgery of the face. © 2008 Springer Science+Business Media, LLC and International Society of Aesthetic Plastic Surgery.

Power, Pedagogy and Participation: ethics and pragmatics in research with young people

This article addresses issues of methodology and ethical reflexivity when attempting to investigate the opinions of young people. Drawing specifically on three studies of young people's understandings of citizenship and their views on topical issues, two from England and one from Lebanon, the authors present ways in which the ethical and practical challenges of such research can be met. While acknowledging the power relationship between researchers and informants, they suggest that what they call ‘pedagogical research approaches’ built on a participative methodology can open up a space where both parties benefit. They argue that, when working in schools, teacher educators can take advantage of this status to present themselves simultaneously as insiders and outsiders. The authors have devised what are intended to be non-exploitative research instruments that permit the gathering of useful qualitative data during a short encounter. They illustrate their approach with examples of classroom activities they have developed to provide simultaneously a valid learning experience and usable data.

"No Artist has Ethical Sympathies": Oscar Wilde, Aesthetics, and Moral Evolution

“There is no mode of action, no form of emotion, that we do not share with the lower animals” (137). This evolutionary claim is not attributable to Darwin, but to Oscar Wilde, who allows Gilbert to voice this bold assertion in “The True Function of Criticism.” While critics have long wrestled with the ethical stance and coherence of Wilde's writings, they have overlooked a significant influence on his work: debates concerning the evolution of morality that animated the periodicals in which he was writing. Wilde was fascinated by the proposition that complex human behaviours, including moral and aesthetic responses, might be traced back to evolutionary impulses. Significantly, he also wrote for a readership already engaged with these controversies.
