Hot Electron Bolometer Development for a Submillimeter Heterodyne Array Camera

We are developing Nb diffusion-cooled Hot Electron Bolometers (HEBs) for a large-format array submillimeter camera. We have fabricated Nb HEBs using a new angle deposition process. We have characterized these devices using heterodyne mixing at 20 GHz. We also report on optimizations in the fabrication process that improve device performance.Comment: 2005 International Symposium on Space Terahertz Technolog

From Analogue to Image Retrieval: Concepts of Archival Art in Daniel Blaufuks

From Analogue to Image Retrieval: Concepts of Archival Art in Daniel Blaufuks, seeks to explore a question first triggered by the viewing of Daniel Blaufuks’s Constellation series in his exhibition-project, All the Memory of the World, part one (2014): might digital databases and image retrieval systems be viewed as developments of archival processes and thinking? Has the touted rupture between analogue and digital occurred, or does archival art live in them both? With a career that spans several decades, Blaufuks has been deeply engaged with questions surrounding the Holocaust, exile, memory and postmemory. Photography, film and archival material have been the tools chosen for his excavations; nonetheless, it is impossible to overlook the influence of literature in the artist’s work. Having begun with the appropriation of physical archival material, such as photographic albums, polaroids or slides, Blaufuks has also employed digital images and image-retrieval systems such as Google Image. In the view to proceed with an analysis on the crucial argument of this thesis, I have divided it into to three sections. The first, Daniel Blaufuks: The ‘Material’ Archive, as the name indicates, focuses on considerations on the so-called material archive, meaning the analogue archive. Daniel Blaufuks: Writing with Images, the second section, is devoted to two thematic components of the artist’s oeuvre: memory and literature. Here I equally offer a comparative analysis between Blaufuks and the works of writers Georges Perec and W. G. Sebald. In Daniel Blaufuks: Traversing the Archive, the final section, I return to the theoretical frameworks surrounding the archive, yet one founded on 0s and 1s rather than paper and ink. In writing From Analogue to Image Retrieval: Concepts of Archival Art in Daniel Blaufuks, I strive to illuminate the continuities from analogue to digital archives, and analogue to digital archival art practices. Blaufuks’s ease and breadth in the incorporation of a variety of media into his projects stands as an ideal case study for the exploration of the questions I put forward in this thesis.From Analogue to Image Retrieval: Concepts of Archival Art in Daniel Blaufuks, explora uma questão desencadeada pela série Constelações de Daniel Blaufuks no seu projeto-exposição, Toda a Memória do Mundo, parte um (2014): poderão bases de dados e sistemas de recuperação de imagens ser vistos como extensões de processos e de concepções do arquivo? Terá a ruptura entre analógico e digital ocorrido, ou será que a arte arquivística é transversal a ambos? Com uma carreira que se estende por várias décadas, Blaufuks tem desenvolvido projectos relacionados com questões em torno do Holocausto, exílio, memória e pós memória. Fotografia, imagem em movimento e material de arquivo são as ferramentas escolhidas pelo artista para as suas escavações; no entanto, é impossível ignorar a influência da literatura na sua obra. Tendo começado com a apropriação de material de arquivo, como álbuns fotográficos, polaroids ou slides, Blaufuks emprega também imagens digitais e motores de busca de imagens como o Google Image nos seus projectos mais recentes. A fim de prosseguir com uma análise da questão central desta tese, a mesma foi dividida em três secções. A primeira, Daniel Blaufuks: The ‘Material’ Archive, tem como foco considerações sobre o arquivo analógico. Já Daniel Blaufuks: Writing with Images, a segunda secção, é dedicada a duas componentes temáticas da obra do artista: memória e literatura. Aqui, procedo igualmente a uma análise comparativa entre Blaufuks e as obras dos escritores Georges Perec e W. G. Sebald. Em Daniel Blaufuks: Traversing the Archive, a secção final, regresso às estruturas teóricas associadas ao arquivo, olhando no entanto para um arquivo construído sobre 0s e 1s ao invés de papel e tinta. Com From Analogue to Image Retrieval: Concepts of Archival Art in Daniel Blaufuks, procuro iluminar continuidades entre arquivos analógicos e digitais, bem como estabelecer paralelos entre o uso de sistemas analógicos e digitais em práticas de arte de arquivo. A facilidade com que Blaufuks integra uma variedade de formatos e média no seu trabalho faz com que o artista seja o estudo de caso ideal para a exploração das questões que apresento nesta tese

Memória e Intertextualidade em Mãos de Cavalo e Reparação

Segundo a crítica literária Tiphaine Samoyault, a intertextualidade é um fenômeno comum a todos os textos e consiste na relação que eles estabelecem entre si. O nosso objetivo é analisar a intertextualidade entre as narrativas Reparação de Ian McEwan e Mãos de Cavalo de Daniel Galera. Analisaremos a memória e o sentimento de culpa que a personagem-narradora Briony Tallis e Hermano, o Mãos de cavalo, carregam, bem como a maneira que encontraram para lidar com este problema.Abstract According to the literary critic Tiphaine Samoyault, intertextuality is a common phenomenon to all texts and it consists in the relationship they establish among themselves. Our goal is to analyse the intertextuality between the narratives Atonement by Ian McEwan and Horse Hands by Daniel Galera. The memory and the feeling of guilt that the character-narrator Briony Tallis and Hermano, the Horse hands, carry will be analysed, as well as the way they found to deal with this problem

Simulations of the Kelvin-Helmholtz instability driven by coronal mass ejections in the turbulent corona

Recent high resolution AIA/SDO images show evidence of the development of the Kelvin-Helmholtz instability, as coronal mass ejections (CMEs) expand in the ambient corona. A large-scale magnetic field mostly tangential to the interface is inferred, both on the CME and on the background sides. However, the magnetic field component along the shear flow is not strong enough to quench the instability. There is also observational evidence that the ambient corona is in a turbulent regime, and therefore the criteria for the development of the instability are a-priori expected to differ from the laminar case. To study the evolution of the Kelvin-Helmholtz instability with a turbulent background, we perform three-dimensional simulations of the incompressible magnetohydrodynamic equations. The instability is driven by a velocity profile tangential to the CME-corona interface, which we simulate through a hyperbolic tangent profile. The turbulent background is generated by the application of a stationary stirring force. We compute the instability growth-rate for different values of the turbulence intensity, and find that the role of turbulence is to attenuate the growth. The fact that the Kelvin-Helmholtz instability is observed, sets an upper limit to the correlation length of the coronal background turbulence

Systematic Physics Constrained Parameter Estimation of Stochastic Differential Equations

A systematic Bayesian framework is developed for physics constrained parameter inference ofstochastic differential equations (SDE) from partial observations. The physical constraints arederived for stochastic climate models but are applicable for many fluid systems. A condition isderived for global stability of stochastic climate models based on energy conservation. Stochasticclimate models are globally stable when a quadratic form, which is related to the cubic nonlinearoperator, is negative definite. A new algorithm for the efficient sampling of such negative definite matrices is developed and also for imputing unobserved data which improve the accuracy of theparameter estimates. The performance of this framework is evaluated on two conceptual climatemodels

The Orion constellation as an installation - An innovative three dimensional teaching and learning environment

Visualising the three dimensional distribution of stars within a constellation is highly challenging for both students and educators, but when carried out in an interactive collaborative way it can create an ideal environment to explore common misconceptions about size and scale within astronomy. We present how the common table top activities based upon the Orion constellation miss out on this opportunity. Transformed into a walk-through Orion installation that includes the position of our Solar system, it allows the students to fully immerse themselves within the model and experience parallax. It enables participants to explore within the installation many other aspects of astronomy relating to sky culture, stellar evolution, and stellar timescales establishing an innovative learning and teaching environment.Comment: 2 pages, submitted to The Physics Teacher - Colum
