An investigation into the loss of the Brazilian space programme's launch vehicle VLS-1 V03

There has been a rapid increase in the complexity and integration of many safety-critical systems. In consequence, it is becoming increasingly difficult to identify the causes of incidents and accidents back through the complex interactions that lead to an adverse event. At the same time, there is a growing appreciation of the need to consider a broad range of contextual factors in the aftermath of any mishap. A number of regulators, operators and research teams have responded to these developments by proposing novel techniques to support the analysis of complex, safety-critical incidents. It is important to illustrate these different approaches by applying them to a number of common case studies. The following pages, therefore, show how STAMP and AcciMap might support the Serviço Público Federal investigation into the explosion and fire of the Brazilian launch vehicle VLS-1 VO3. © 2006 Elsevier Ltd.

Design Minds Refresh Toolkit

The Design Minds Refresh Toolkit was one of six K7-12 secondary school design toolkits commissioned by the State Library of Queensland (SLQ) Asia Pacific Design Library (APDL), to facilitate the delivery of the Stage 1 launch of its Design Minds online platform (www.designminds.org.au) partnership initiative with Queensland Government Arts Queensland and the Smithsonian Cooper-Hewitt National Design Museum, on June 29, 2012. Design Minds toolkits are practical guides, underpinned by a combination of one to three of the Design Minds model phases of ‘Inquire’, ‘Ideate’ and ‘Implement’ (supported by at each stage with structured reflection), to enhance existing school curriculum and empower students with real life design exercises, within the classroom environment. Toolkits directly identify links to Naplan, National Curriculum, C2C and Professional Standards benchmarks, as well as the student capabilities of successful and creative 21st century citizens they seek to engender through design thinking. Inspired by ideas from a design project for second year Interior Design students at QUT School of Design, this toolkit explores, through five distinct exercises, different design tools and ways to approach the future design of environments (bathrooms) to facilitate the daily washing ritual, while addressing diverse and changing social, cultural, technological and environmental challenges. The Design Minds Refresh Toolkit particularly aims to promote ‘Lateral Thinking’ attitudes and empathy as an approach to create unusual and sustainable solutions to future problems that may affect our daily behavioural routines, and the spaces that facilitate them. More generally, it aims to facilitate awareness in young people, of the role of design in society and the value of design thinking skills in generating strategies to solve basic to complex systemic challenges, as well as to inspire post-secondary pathways and idea generation for education. The toolkit encourages students and teachers to develop sketching, making, communication, presentation and collaboration skills to improve their design process, as well as explore further inquiry (background research) to enhance the ideation exercises. Exercise 1 focuses on the ‘Inquire’ and ‘Ideate’ phases, Exercise 2 and 3 build on ideation skills, and Exercise 4 and 5 concentrate on the ‘Implement’ phase. Depending on the intensity of the focus, the unit of work could be developed over a 4-5 week program (approximately 10-12 x 60 minute lessons/workshops) or as smaller workshops treated as discrete learning experiences. The toolkit is available for public download from http://designminds.org.au/refresh/ on the Design Minds website. Exercise 2 (Other People’s Shoes) and Exercise 3 (The Future Bathroom) of the toolkit were used as content for the inaugural Design Minds Professional Development Workshop on June 28, 2012 to pre-launch the website to Queensland teachers.

Design Minds The Big Picture Toolkit

The Design Minds The Big Picture Toolkit was one of six K7-12 secondary school design toolkits commissioned by the State Library of Queensland (SLQ) Asia Pacific Design Library (APDL), to facilitate the delivery of the Stage 1 launch of its Design Minds online platform (www.designminds.org.au) partnership initiative with Queensland Government Arts Queensland and the Smithsonian Cooper-Hewitt National Design Museum, on June 29, 2012. Design Minds toolkits are practical guides, underpinned by a combination of one to three of the Design Minds model phases of ‘Inquire’, ‘Ideate’ and ‘Implement’ (supported by at each stage with structured reflection), to enhance existing school curriculum and empower students with real life design exercises, within the classroom environment. Toolkits directly identify links to Naplan, National Curriculum, C2C and Professional Standards benchmarks, as well as the student capabilities of successful and creative 21st century citizens they seek to engender through design thinking. Inspired by the Unlimited: Designing for the Asia Pacific Generation Workshop 2010 (http://eprints.qut.edu.au/47762/), this toolkit explores, through three distinct exercises, ‘design for the other 90%’, addressing tools and approaches to diverse and changing social, cultural, technological and environmental challenges. The Design Minds The Big Picture Toolkit challenges students to be active agents for change and to think creatively and optimistically about solutions to future global issues that deliver social, economic and environmental benefits. More generally, it aims to facilitate awareness in young people, of the role of design in society and the value of design thinking skills in generating strategies to solve basic to complex systemic challenges, as well as to inspire post-secondary pathways and idea generation for education. The toolkit encourages students and teachers to develop sketching, making, communication, presentation and collaboration skills to improve their design process, as well as explore further inquiry (background research) to enhance the ideation exercises. Exercise 1 focuses on the ‘Inquire’ phase, Exercise 2 the ‘Inquire’ and ‘Ideate’ phases, and Exercise 3 concentrates on the ‘Implement’ phase. Depending on the intensity of the focus, the unit of work could be developed over a 4-5 week program (approximately 4-6 x 60 minute lessons/workshops) or as smaller workshops treated as discrete learning experiences. The toolkit is available for public download from http://designminds.org.au/the-big-picture/ on the Design Minds website.

Design Minds Tomorrow's Classroom Toolkit

The Design Minds Tomorrow’s Classroom Toolkit was one of six K7-12 secondary school design toolkits commissioned by the State Library of Queensland (SLQ) Asia Pacific Design Library (APDL), to facilitate the delivery of the Stage 1 launch of its Design Minds online platform (www.designminds.org.au) partnership initiative with Queensland Government Arts Queensland and the Smithsonian Cooper-Hewitt National Design Museum, on June 29, 2012. Design Minds toolkits are practical guides, underpinned by a combination of one to three of the Design Minds model phases of ‘Inquire’, ‘Ideate’ and ‘Implement’ (supported by at each stage with structured reflection), to enhance existing school curriculum and empower students with real life design exercises, within the classroom environment. Toolkits directly identify links to Naplan, National Curriculum, C2C and Professional Standards benchmarks, as well as the student capabilities of successful and creative 21st century citizens they seek to engender through design thinking. This toolkit explores, through four distinct exercises, different design tools and ways to approach the future design of environments (classrooms/schools) to facilitate the Reggio Emilia philosophy of learning, while addressing diverse and changing social, cultural, technological and environmental challenges. The Design Minds Tomorrow’s Classroom Toolkit encourages students to explore architecture and interior design, and to think about their (life-long) learning as a product of inspiring interactions with people and the environments around them, and that their potential role in contributing to both delightful and functional design solutions requires a deep understanding of the user experience. More generally, it aims to facilitate awareness in young people, of the role of design in society and the value of design thinking skills in generating strategies to solve basic to complex systemic challenges, as well as to inspire post-secondary pathways and idea generation for education. The toolkit encourages students and teachers to develop sketching, making, communication, presentation and collaboration skills to improve their design process, as well as explore further inquiry (background research) to enhance the ideation exercises. Exercise 1 focuses on the ‘Inquire’ and ‘Ideate’ phases, Exercise 2 on the ‘Inquire’, Exercise 3 builds on ideation skills, and Exercise 4 concentrates on the ‘Implement’ phase. Depending on the intensity of the focus, the unit of work could be developed over a 2-5 week program (approximately 4-10 x 60 minute lessons/workshops) or as smaller workshops treated as discrete learning experiences. The toolkit is available for public download from http://designminds.org.au/tomorrows-classroom/ on the Design Minds website. This toolkit inspired the authorship and facilitation of a 2-day design workshop entitled Learning Environment 2050 at John Paul College, Daisy Hill, Brisbane on the 15-16 August 2013. 120 Grade 7 students and their teachers, under the mentorship of two design academics, 3 QUT design students and a professional architect, as part of a QUT School of Design Project Week community engagement activity, explored the formulation of a participatory design brief for the redesign of the school’s Wesley Precinct (including classrooms, a sustainable farm and recreation areas).

Acordo Aeroespacial Teuto-Brasileiro (1969-1989; 1990-2001 e 2002-2011): uma cooperação complementar

Este projeto de dissertação se propõe a analisar a cooperação aeroespacial entre o Brasil e a Alemanha de 1969 a 2011 em três recortes temporais: 1969 a 1989, 1990 a 2001 e 2002 a 2011. Seguindo as bases teóricas de classificação da CID (Cooperação Internacional para o Desenvolvimento), e apoiada em pesquisa de campo conduzida em ambos os países, este trabalho apresenta um novo conceito de cooperação que, até onde a pesquisa bibliográfica aqui conduzida avaliou, constitui uma contribuição original deste trabalho: a Cooperação Complementar. A cooperação aeroespacial teuto-brasileira é pouco conhecida e divulgada, embora tenha completado vigorosas quatro décadas de exitosa existência. A conclusão de êxito desta cooperação encontrou lastro em pesquisa de campo conduzida pela autora no Brasil (IAE Instituto de Aeronáutica e Espaço) e na Alemanha (DLR Deutsche Zentrum für Luft- und Raumfahrt), consubstanciada por quatro entrevistas (SILVA, 2011a), (SILVA, 2011c), (SILVA, 2011d) e (SILVA, 2011e) realizadas junto a importantes representantes destes dois centros. Os conhecimentos extraídos por meio destas entrevistas agregaram, no entender desta autora, importantes informações à bibliografia específica e relativamente escassa disponível em ambos os países.O êxito defendido nesta dissertação fundamenta-se não apenas na longevidade advinda dos 40 anos de existência desta Cooperação, na sua capacidade de renovação e na complementaridade atingida, mas sobretudo pela consecução dos diversos objetivos técnico-científicos integrantes do escopo do referido Tratado, muitos dos quais responsáveis por importantes desdobramentos de tecnologias em outras áreas do saber, tais como o projeto DEBRA 25 (SCHUSTER, 2011), de energia eólica, e o projeto VLS (Veículo Lançador de Satélites), que utiliza como seus motores os foguetes desenvolvidos no escopo desta Cooperação.

Avaliação do Sistema Nacional de Desenvolvimento das Atividades Espaciais

An accident with Brazilian Satellite Launching Vehicle (SLV-1 V03) third prototype in August, 2003 at Alcântara Base, in the State of Maranhão, dramatically exposed accumulated deficiencies affecting Brazilian space sector. A report regarding this accident published by Ministry of Defense recognized the relevance of organizational dimension for the success of Brazilian space policy. In this case study, the author analyses sector organizational structure - the National Space Activities Development System (NSADS) - to evaluate its adequacy to policy development requisites. The Theory of Structural Contingency - TSC provided the analytical framework adopted in the research complemented by two organizational approaches that focuses high risk systems: Normal Accident Theory - NAT and High Reliability Theory - HRT. The last two approaches supported the analysis of NSADS's organizations which are, according to Charles Perrow definition, directly involved in developing high risk technological systems and their relationship with the System. The case study was supplemented with a brief comparison between NSADS and the organizational structures of North-American and French civilian space agencies, respectively, NASA and CNES, in order to subsidize organizational modeling of Brazilian System.

Fashion as consumer entrepreneurship : emergent risk culture, social network markets, and the launch of 'Vogue' in China

China has a reputation as an economy based on utility: the large-scale manufacture of low-priced goods. But useful values like functionality, fitness for purpose and efficiency are only part of the story. More important are what Veblen called ‘honorific’ values, arguably the driving force of development, change and value in any economy. To understand the Chinese economy therefore, it is not sufficient to point to its utilitarian aspect. Honorific status-competition is a more fundamental driver than utilitarian cost-competition. We argue that ‘social network markets’ are the expression of these honorific values, relationships and connections that structure and coordinate individual choices. This paper explores how such markets are developing in China in the area of fashion and fashion media. These, we argue, are an expression of ‘risk culture’ for high-end entrepreneurial consumers and producers alike, providing a stimulus to dynamic innovation in the arena of personal taste and comportment, as part of an international cultural system based on constant change. We examine the launch of Vogue China in 2005, and China’s reception as a fashion player among the international editions of Vogue, as an expression of a ‘decisive moment’ in the integration of China into an international social network market based on honorific values.

Knowledge unlatched announces the launch of its pilot collection [Blog]

Frances Pinter and I have been visiting fellows at the Big Innovation Centre for more than a year now. Tucked away in a corner, inspired by BIC’s open innovation vision, we have been attempting to solve a problem that continues to perplex many in the era of digital affordance: creating sustainable markets for high quality new content that include free access for end users.

An Optimal g-Guidance Scheme for Satellite Launch Vehicles

A closed-loop steering logic based on an optimal (2-guidance is developed here. The guidance system drives the satellite launch vehicle along a two- or three- dimensional trajectory for placing the payload into a specified circular orbit. The modified g-guidance algorithm makes use of the optimal required velocity vector, which minimizes the total impulse needed for an equivalent two-impluse transfer from the present state to the final orbit. The required velocity vector is defined as velocity of the vehicle on the hypothetical transfer orbit immediately after the application of the first impulse. For this optimal transfer orbit, a simple and elegant expression for the Q-matrix is derived. A working principle for the guidance algorithm in terms of the major and minor cycles, and also for the generation of the steering command, is outlined.

Editorial of "International Journal of Critical Indigenous Studies, Volume 6, Number 1, 2013"

This edition of the International Journal of Critical Indigenous Studies marks the tenth since the journal’s launch in 2008. During that time, over forty articles and eleven book reviews have been published, which is testament to the continuing upward trajectory of Critical Indigenous Studies. Although there continues to be an increasing range of areas of Indigenous research to which a critical focus is brought to bear, a consistent issue for many of the journal’s contributors has been the delineation and application of Indigenous methods and methodologies in social research. The present edition is no exception, with two articles focussing on Indigenous-centred research. The first, by Krystal Summers, reflexively explores the author’s experiences as an undergraduate student undertaking Indigenous-centred research in Peru. As an Indigenous First Nations woman, Summers was mindful that her research practice was faithful to the ethics and protocols outlined in her original project proposal. Her subsequent ‘journey of critical reflexive understanding and storytelling’ supports the proposition of current literature in Indigenous research methodologies that a properly critical Indigenous ethnography will naturally enjoin with Indigenous epistemologies and methodologies.

CXCL10, CXCL11, HLA-A and IL-1β are induced in peripheral blood mononuclear cells from women withChlamydia trachomatisrelated infertility

Chlamydia trachomatis infections can result in the development of serious sequelae such as pelvic inflammatory disease and tubal infertility. In this study, peripheral blood mononuclear cells from women who were undergoing or had recently undergone IVF treatment were cultured ex vivo with C. trachomatis to identify the immune responses associated with women who had serological evidence of a history of Chlamydia infection. Cytokines secreted into the supernatant from the cultures were measured using ELISA, and the level of IL-1β was found to be significantly higher in Chlamydia positive women than Chlamydia negative women. qRT-PCR analysis of the expression of 88 immune-related genes showed trends towards an upregulation of CXCL10, CXCL11 and HLA-A in Chlamydia positive women compared with Chlamydia negative women. These findings support that some women launch a more marked proinflammatory response upon infection with C. trachomatis and this may be associated with why C. trachomatis induces infertility in some infected women.

Determination of optimal trajectory under design constraints for a satellite launch vehicle

An optimal pitch steering programme of a solid-fuel satellite launch vehicle to maximize either (1) the injection velocity at a given altitude, or (2) the size of circular orbit, for a given payload is presented. The two-dimensional model includes the rotation of atmosphere with the Earth, the vehicle's lift and drag, variation of thrust with time and altitude, inverse-square gravitational field, and the specified initial vertical take-off. The inequality constraints on the aerodynamic load, control force, and turning rates are also imposed. Using the properties of the central force motion the terminal constraint conditions at coast apogee are transferred to the penultimate stage burnout. Such a transformation converts a time-free problem into a time-fixed one, reduces the number of terminal constraints, improves accuracy, besides demanding less computer memory and time. The adjoint equations are developed in a compact matrix form. The problem is solved on an IBM 360/44 computer using a steepest ascent algorithm. An illustrative analysis of a typical launch vehicle establishes the speed of convergence, and accuracy and applicability of the algorithm.

Launch Envelope Optimization of Virtual Sliding Target Guidance Scheme

This paper presents an optimization of the performance of a recently proposed virtual sliding target (VST) guidance scheme in terms of maximization of its launch envelope for three- dimensional (3-D) engagements. The objective is to obtain the launch envelope of the missile using the VST guidance scheme for different lateral launch angles with respect to the line of sight (LOS) and demonstrate its superiority over kinematics-based guidance laws like proportional navigation (PN). The VST scheme uses PN as its basic guidance scheme and exploits the relation between the atmospheric properties, missile aerodynamic characteristics, and the optimal trajectory of the missile. The missile trajectory is shaped by controlling the instantaneous position and the speed of a virtual target which the missile pursues during the midcourse phase. In the proposed method it is shown that an appropriate value of initial position for the virtual target in 3-D, combined with optimized virtual target parameters, can significantly improve the launch envelope performance. The paper presents the formulation of the optimization problem, obtains the approximate models used to make the optimization problem more tractable, and finally presents the optimized performance of the missile in terms of launch envelope and shows significant improvement over kinematic-based guidance laws. The paper also proposes modification to the basic VST scheme. Some simulations using the full-fledged six degrees-of-freedom (6-DOF) models are also presented to validate the models and technique used.

A Nonlinear Approach for Re-entry Guidance of Reusable Launch Vehicles Using Model Predictive Static Programming

A nonlinear suboptimal guidance scheme is developed for the reentry phase of the reusable launch vehicles. A recently developed methodology, named as model predictive static programming (MPSP), is implemented which combines the philosophies of nonlinear model predictive control theory and approximate dynamic programming. This technique provides a finite time nonlinear suboptimal guidance law which leads to a rapid solution of the guidance history update. It does not have to suffer from computational difficulties and can be implemented online. The system dynamics is propagated through the flight corridor to the end of the reentry phase considering energy as independent variable and angle of attack as the active control variable. All the terminal constraints are satisfied. Among the path constraints, the normal load is found to be very constrictive. Hence, an extra effort has been made to keep the normal load within a specified limit and monitoring its sensitivity to the perturbation.
