Science, technology and utopias in the work of contemporary women artists
No full textThis dissertation examines the work of artists Alice Aycock, Agnes Denes, Martha Rosler and Carolee Schneemann, created between the late 1960s and the mid-1980s, which incorporated science and technology as subject and media. It represents the first focused examination of the conceptual use of science and technology by American women artists during the Cold War. I argue that, for these artists, science and technology represented a realm of investigation replete with negative associations in the wake of the Vietnam War, but also ripe with opportunities for change. Motivated by the contemporary American women's movement, these artists leveraged theories in physics, cosmology and systems, as well as new technologies such as video, in order to subvert modernist, male-centered, heroic, painterly styles, in addition to the traditional economic structures of the gallery, museum and dealer. This study sheds new light on conceptual art by re-centering the use of technology, generally treated as a conservative trend and excised from avant-garde histories, as a means for critique of Cold War society and as a method for imagining alternative concepts of human community. At stake in this investigation are domains of knowledge and power from which women have been historically excluded.
Informed by New Left and counter-culture criticism of nuclear weapons and the Vietnam War arising from influential theorists, such as Herbert Marcuse and Lewis Mumford, these artists associated the industries of science and technology with the military-industrial complex, which was reviled as representative of a closed, mechanistic "technological society." However Marcuse, the media-acknowledged guru of the New Left (a left-wing international movement composed of social activist groups formed in the 1960s), also inspired the counter-culture to imagine an alternative society in which "science and technology are the great vehicles of liberation." Thus, while these artists subjected the patriarchal institutions and industries of science and technology to withering attack, they also redeployed their implicit notion of progress in feminist utopian visions of a different future.Ph.D.Includes bibliographical references (p. 304-331)by Christine Filippon
An evaluation of the historical issues associated with achieving non-helicopter V/STOL capability and the search for the flying car
No full textCopyright @ 2010 The Royal Aeronautical Society. This article is the final author version of the published paper.Combined Vertical and short take-off and landing, or ‘V/STOL’ capability has been of great demand and interest in the field of aeronautics since the creation of the aircraft. V/STOL capability is a targeted capability for many projected or prototype future aircraft. Past V/STOL aircraft are reviewed and analysed with regard to their performance parameters. This research has found two embedded categories in this class of aircraft based on their propulsion systems, i.e. jet and non-jet propulsion, and highlights the significant performance differences between them. In light of historical experience the performance of a relatively new class of aircraft, the flying cars, has been evaluated

The definition of the effective interaction energy for astrophysical relevant reactions
No full textExperimental studies of nuclear reactions of astrophysical interest are hampered by the exponential drop of the cross-section with decreasing energy. Generally, the effects of the projectile energy loss in the target cannot be neglected and the reaction yield is proportional to the average value of the cross-section over the interaction energies inside the target. Local cross-section values, instead of averaged, are needed to evaluate stellar reaction rates. To deal with this, several different effective interaction energy definitions have been introduced during the years, leading to potentially discrepant results. Thus, a well-defined procedure for data reduction is required. This work briefly reviews the theoretical ground for the experimental cross-section data reduction and the effective interaction energies definitions up to now introduced. The self-consistent approach introduced by B.W. Filippone et al. is discussed and its application to the data analysis of non-resonant and narrow-resonant reactions is presented. A comparison of the results obtained using the different approaches is also reported

Plausibility or truth. Archival notes and reflections on the canvas of the ‘Militant and triumphant Church’ ascribed to Jacopo Zucchi
No full textWhile retracing the traditional history of the painting, which was fi rst ascribed to Federico Zuccari and later to
Jacopo Zucchi, the author hereby presents the long and painstaking research that has gradually confi rmed this
second hypothesis. The reader will, therefore, fi nd a synthesis of the history of this painting, which was surely
enough fi rst hosted in St Peter's Basilica, then moved to the Church of St Catherine of Alexandria and fi nally to
the Vatican Sacristy. Based on a number of inconsistencies which emerged during archival research, doubts still persist with regard to
the historicity of this historical-artistic tradition. Despite the fact that scholars are fi rmly inclined to ascribe the
painting to Zucchi, some unpublished documents tend to undermine this assumption, while still implying that the
painting might be by an artist of the Zuccari famil
A comparative evaluation of stochastic-based inference methods for Gaussian process models
No full textGaussian Process (GP) models are extensively used in data analysis given their flexible modeling capabilities and interpretability. The fully Bayesian treatment of GP models is analytically intractable, and therefore it is necessary to resort to either deterministic or stochastic approximations. This paper focuses on stochastic-based inference techniques. After discussing the challenges associated with the fully Bayesian treatment of GP models, a number of inference strategies based on Markov chain Monte Carlo methods are presented and rigorously assessed. In particular, strategies based on efficient parameterizations and efficient proposal mechanisms are extensively compared on simulated and real data on the basis of convergence speed, sampling efficiency, and computational cost. © 2013 The Author(s)
