An Interview with Cass R. Sunstein: Author of The World According to Star Wars
No full textThe guest editors of special issue 12, Jason W. Ellis and Sean Scanlan, interview Cass R. Sunstein, the Robert Walmsley University Professor at Harvard, where he is founder and director of the Program on Behavioral Economics and Public Policy. He is the author of many books, including the bestseller Nudge: Improving Decisions about Health, Wealth, and Happiness (with Richard H. Thaler). His 2016 book The World According to Star Wars attempts to understand the Star Wars universe in ten chapters through the lenses of Sunstein’s academic interests, namely: culture, sociology, psychology, behavioral science, and political science. The book is both personal and theoretical, practical and academic. It takes accurate measure of the genesis of the movies, the movies themselves, and briefly, but trenchantly, it examines concepts such as reputational cascades and speculates on what Star Wars can teach viewers about constitutional disputes
Mapping customer needs to engineering characteristics: an aerospace perspective for conceptual design
No full textDesigning complex engineering systems, such as an aircraft or an aero-engine, is immensely challenging. Formal Systems Engineering (SE) practices are widely used in the aerospace industry throughout the overall design process to minimise the overall design effort, corrective re-work, and ultimately overall development and manufacturing costs. Incorporating the needs and requirements from customers and other stakeholders into the conceptual and early design process is vital for the success and viability of any development programme. This paper presents a formal methodology, the Value-Driven Design (VDD) methodology that has been developed for collaborative and iterative use in the Extended Enterprise (EE) within the aerospace industry, and that has been applied using the Concept Design Analysis (CODA) method to map captured Customer Needs (CNs) into Engineering Characteristics (ECs) and to model an overall ‘design merit’ metric to be used in design assessments, sensitivity analyses, and engineering design optimisation studies. Two different case studies with increasing complexity are presented to elucidate the application areas of the CODA method in the context of the VDD methodology for the EE within the aerospace secto
An aerospace component cost modelling study for value driven design
No full textDemand is increasing in aero-engine products for better efficiency and environmental performance whilst keeping the cost low. Unlike performance, the physics behind cost is least understood. This paper presents a proposed unit cost modelling methodology applied to a Rolls-Royce aero-engine fan blade. An objective of the cost model is the allow engineers to understand the breakdown of cost. A value driven design concept is outlined and presents an opportunity to conduct design optimisation
A generic operational simulation for early design civil unmanned aerial vehicles
No full textContemporary aerospace programmes often suffer from large cost overruns, delivery delays and inferior product quality. This is caused in part by poor predictive quality of the early design phase processes with regards to the operational environment of a product. This paper develops the idea of a generic operational simulation that can help designers to rigorously analyse and test their early product concepts. The simulation focusses on civil Unmanned Air Vehicle products and missions to keep the scope of work tractable. The research agenda is introduced along with ideas, initial results and future work. Designers specify details about their product, its environment and anticipated operational procedures. The simulation returns information that can help to estimate the value of the product using the value-driven design approach. Information will include recurring and non-recurring mission cost items. The research aim is to show that an operational simulation can improve early design concepts, thereby reducing delays and cost overruns. Moreover, a trade-off between mission fidelity and model generality is sought along with a generic ontology of civil Unmanned Air Vehicle missions and guidelines about capturing operational informatio
Timothy (Tim) Scanlan
No full textBIOGRAPHICAL INFORMATION: Timothy (Tim) Scanlan is a Caucasian male born on September 15, 1946. He is the third out of seven kids. Both of his parents worked. He grew up Catholic. SUBJECTS DISCUSSED: Scanlan starts by describing how he came from a big family, and talks about how they were all close knit, as well as what family pets they had. He mentions how it seemed like they were financially getting by, but that his parents probably had a depression-era mentality when it came to conversations about money. He briefly discusses his religious upbringing, and how it was important in their family. He goes on to describe his experience with growing up in the neighborhood, and how everyone knew each other and would have huge neighborhood nights. Scanlan mentions the value of loyalty. Afterwards, he touches on the television shows that he watched when he was growing up, as well as how schooling was very positive. He ends the interview by describing the local issues affecting the neighborhood, such as how they grew up in a time of economic boom, the Vietnam war, Kennedy’s, and Martin Luther King Jr.\u27s assassination, and growing up with people that were different from him.https://digitalcommons.csp.edu/tc-ohp_interviews_stp/1012/thumbnail.jp
Traces of Another Time : History and Politics in Postwar British Fiction /
No full textIs the historical novel the outmoded genre that some people imagine--form inseparable from romanticism, nationalism, and the nineteenth century? In this stimulating volume, Margaret Scanlan answers a convincing "no," as she demonstrates the relevance of historical novels by well-known figures such as Anthony Burgess, John le Carr, Graham Greene, Doris Lessing, Iris Murdoch, and Paul Scott, as well as by less well established writers such as Joseph Hone and Thomas Kilroy. Scanlan shows what a skeptical, experimental approach to the relationship between history and fiction these writers adopt and how radically they depart from the mimetic conventions usually associated with historical novels. Drawing on contemporary historiography and literary theory, Scanlan defines the problem of writing historical fiction at a time when people see the subject of history as fragmentary and uncertain. The writers she discusses avoid the great events of history to concentrate on its margins: what interests them is history as it is experienced, usually reluctantly, by human beings who would rather be doing something else. The first section of the book looks at fictional representations of England's difficult history in Ireland; the second examines spies, aliens, and the loss of public confidence; and the third probes the theme of Apocalypse, nuclear or otherwise, and depicts the collapse of the British Empire as an instance of the greatly diminished importance of Western culture in the world.Originally published in 1990.The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These paperback editions preserve the original texts of these important books while presenting them in durable paperback editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.Is the historical novel the outmoded genre that some people imagine--form inseparable from romanticism, nationalism, and the nineteenth century?

On axisymmetric adhesive joints with graded interface stiffness
No full textAn improved analytical model is presented for the stress analysis of interface stiffness graded axisymmetric adhesive joints. The governing integro-differential equation of the problem is obtained through a variational method which minimizes the complementary energy of the bonded assembly. The joint is composed of similar or dissimilar polar anisotropic and/or isotropic adherends and a functionally modulus graded bondline (FMGB) adhesive. The elastic modulus of the adhesive is functionally graded along the bondlength by assuming smooth modulus profiles which reflect the behavior of practically producible graded bondline. Influence of non-zero radial stresses in the bonded system on shear and normal stresses is evaluated. The stress distribution predicted by this refined model is compared with that of mono-modulus bondline (MMB) model for the same axial tensile load in order to estimate reduction in shear and normal stress peaks in the bondline and the adherends. A systematic parametric study indicates that an optimum joint strength can be achieved by employing a stiffness graded bondline with an appropriate combination of geometrical and material properties of the adherends. This model can also be applied to examine the effects of loss of interface stiffness due to an existing defect and/or damage in the bondlin
Modeling of modulus graded axisymmetric adhesive joints
No full textThis study presents a refined theoretical framework for the stress analysis of modulus graded axisymmetric adhesive joints which takes into account the radial stresses in the bonded assembly. This semi-analytical is based on a variational method which minimizes the complementary energy of the bonded system. The joint consists of similar or dissimilar polar anisotropic composite adherends or metallic adherends and a functionally modulus graded bondline (FMGB) adhesive. The elastic modulus of the adhesive is functionally graded along the bondlength by assuming smooth modulus profiles which reflect the behavior of practically producible graded bondline. The stress distribution predicted by this refined model is compared with that of MMB model which also accounts for in the bonded system to estimate reduction in shear and peel stress peaks in the bondline. The axisymmetric stress analysis reveals that the peel and shear stress peaks in the FMGB are much smaller and the stress distribution is more uniform along its length than those of mono-modulus bondline (MMB) adhesive joints under the same axial tensile load. A systematic parametric study has been conducted by selectively perturbing the material and geometrical properties of the joint in order to study their influence onstress distribution in the bondline. Furthermore, the results suggest that the peel and shear strengths can be optimized by spatially controlling the modulus of theadhesive
Evaluating design decisions in real-time using operations modelling
No full textContemporary design processes of large aerospace products are rigidly focused on customer specifications in order to meet their expectations. Life cycle costs, design space exploration and value engineering are neglected, often leading to substantial cost overruns and delivery delays. Moreover, customer specifications are not scrutinized and design decisions are made ignoring potential operational knowledge. Value-driven design suggests a new approach using flexible customer specifications in order to find optimal designs by exploring the solution space. One aspect of this optimization is the simulation of the anticipated operational life of a product in order to gain operational knowledge and analyse customer specifications. This paper suggests that an operational simulation can be used actively or reactively by designers during the design process to improve a product. It is investigated how an operational simulation can act as a design decision support tool and how it can react to customer specifications. Answers are presented by means of a simulation model recreating the operational life of a Search-and-Rescue Unmanned Air Vehicle developed in parallel at the University of Southampton. The simulation's ability for acting as a decision support tool is explored by conducting a fuel tank size optimization. Reactive capabilities are explored by calculating the surplus value of using UAVs. This exemplifies the derivation of product specifications as the simulation reveals the value and hence usefulness of given customer specifications. It is shown that operational simulations benefit designers and overall product value by analysing product specifications and guiding designers to more informed design decision
