Visual and Near-infrared Astronomy
No full textThe first non-electromagnetic messengers from space were discovered in the early 20th century, but it is only now that multimessenger astronomy is coming into its own. The aim of Multimessenger Astronomy in Practice is to aid an astronomer who is new to research in a particular area of multimessenger astronomy. Covering electromatic radiation from radio through to gamma-rays, and moving on to neutrino, cosmic-ray and gravitational wave astronomy, it gives the reader an overview of the celestial objects detected in each region, the unique methods used to measure them, as well as the principles and methods of data collection, calibration, reduction and analysis. Further chapters cover dark matter, the multimessenger search for extraterrestrial intelligence (SETI), and data science with machine learning. The book will help educate astronomy students taking a multimessenger approach, and add to the knowledge of professional astronomers about what is available in today’s multimessenger toolbox.Key features• Prepares astronomers new to research in a particular area of multimessenger astronomy• Covers modern astrophysics across the electromatic spectrum from radio through to gamma-rays, as well as neutrino, cosmic-ray and gravitational wave astronomy• Details the celestial objects detected in each region, the detection methods used, and the principles and methods of data collection, calibration, reduction and analysis• Includes chapters on dark matter, the multimessenger search for extraterrestrial intelligence (SETI), and data science with machine learningFil: Gurovich, Sebastian.

Palazzo Te allo Specchio: una Mostra tra Classicità e Avanguardia per la Divulgazione del Patrimonio Architettonico
No full textOscar Wilde in “The Picture of Dorian Gray” denounced the double face of beauty: eternal youth at the price of corruption of the soul. Nowadays, the risk befalling architectural heritage is the same: preservation of the monument at the price of its marketing. Which perspectives may arise from such a remark? Problems connected to the 70’s methodologies of preservation appear now as out-of-date due to the cogency of a much relevant problem: the unavailability of the finances needed to carry out even the most ordinary maintenance procedures. The critical urgency is shifting from a cultural to an economical dimension and the present times are not favorable ones. It is necessary, therefore, to make the management of the monument a previous step to its preservation, also for the reason that we understand that nowadays the economic management stands to preservation as oxygen to human life. As people in charge, as being cultural operators before being economic ones, we cannot afford to be deprived of the co- ordination of the process, in order to ensure preservation to be regarded as a primary issue for architecture. How to carry this out? The purpose of the present communication idea is to create a doorway towards the future for architectural design linked to photography, to the digital world and to the survey for architectural heritage. The processing of digital techniques for the design is based upon an attentive inquiry on Luigi Ghirri’s photography and on his personal way of representing the Pianura Padana
A Light That Never Goes Out
No full textThis chapter argues that, in spite of its defeat, humanity in McCarthy’s novel is buried alive as a resilience of ethics. Using Agamben’s notion of bare life and Levinas’s writing on the absolute primacy of ethical relation, the chapter explores McCarthy’s vision of a humanity that is backed up against its limit. For Agamben, the modern paradigm of bare life, characterized by its infinite exposure to death, is the concentration camp where there is no longer any distinction between law and life. The crisis of political existence this implies as well as the divestiture of value that life is exposed to represent the ontological warrants that allow McCarthy to examine the significance of a humanity abandoned to the threshold of its presuppositions. When life is cut back to its intrinsic terms, the only value that seems to remain is pure life (zoē) or life deprived of its political value, in Agamben’s terms. In a colorless landscape of the novel where all distinctions have been burnt to cinders that cover the earth as the ubiquitous remainder of their absolute destruction, the topography of what makes us human, however, can yet be traced as an ethical intrigue that, in spite of all, still flickers in the ashes and powers the novel. For McCarthy, in other words, the call of goodness is what constitutes the gravity of being whose pull, in the end, remains stronger than its fear of death
Normative Qualitätsansprüche an algorithmischen Journalismus
No full textDie fortschreitende Digitalisierung und Automatisierung im Journalismus stellt auch professionsethisches Handeln unter Druck. Dabei erzeugen die automatisierte Textproduktion und deren Verbreitung ethische Fragen auf individueller, organisatorischer und gesellschaftlicher Ebene. Bezogen auf normative Qualitätsansprüche diskutiert der Beitrag Fragen der journalistischen Verantwortung und der Transparenz. Es zeigt sich, dass die Technologie die Dimensionen der Verantwortung vor, während und nach der Nachrichtenproduktion maßgeblich beeinflusst. Neue Akteure spielen dabei ebenso eine zentrale Rolle wie die normativen Ansprüche im Umgang und bei der Kennzeichnung algorithmisch generierter Inhalte
An MPC approach for grid-forming inverters: Theory and experiment
No full textMicrogrids (MGs) interest is growing very fast due to the environment urgency and their capability to integrate renewable energy in a flexible way. In particular, islanded MGs in which distributed energy resources (DERs) are connected to the infrastructure with power electronic converters have attracted the interest of many researchers of both academia and industry because management, control and protection of such systems is quite different from the case of traditional networks. According to their operation mode, MGs that power electronic converters can be divided into grid-forming, grid-feeding and grid-supporting inverters. In particular, grid forming inverters are asked to impose voltage and frequency in the MG. This paper aims to propose a model predictive control (MPC) based approach for grid-forming inverters in an islanded MG. The MPC strategy is implemented because of its capability to define the optimal control actions that contemporarily track the desired reference signals and accounts for equality and inequality constraints. The overall problem formulation (objective function and relevant constraints) is described step by step and considers the specificity of the considered DC source. The proposed approach allows for the obtaining of very good results in terms of readiness against disturbances, even if it requires being fed only by local measurements. In order to validate the developed method, this paper proposes an experimental validation of the designed MPC controller in order to show its correct operation on a real system in a power hardware in the loop set-up using a rapid control prototyping approach
'Goshka Macuga, "Picture Room", 2003' [republished 2017]
No full textAn essay on artist Goshka Macuga's 'Picture Room' at Gasworks in London in 2003, an exhibition of contemporary art that rethought the display space and strategies designed by John Soane for his home-museum in 1824.
A contribution to the series on 'The Artist as Curator', edited by Elena Filipovic for 'Mousse' magazine, it appeared in issue 48 (April 2015), prior to publication in this anthology.
In the interim, this essay was republished in a monograph on Goshka Macuga's work: Mario Mainetti (ed.), 'Before the Beginning and After the End', Fondazione Prada, Milan, 2016
Time-Inhomogeneous Affine Processes
No full textAffine processes are distinguished by their rich structural properties, which makes them favorite when it comes to computations in financial applications of all kind. This fact has been explored and illustrated for the time-homogeneous case in a recent paper by Duffie, Filipovic and Schachermayer. However, there are many situations which require time-dependent parameters, such as when it comes to model calibration. This paper provides a rigorous treatment and complete characterization of time-inhomogeneous affine processesCS

Elena Filipovic, The Apparently Marginal Activities of Marcel Duchamp
No full textElena Filipovic a une idée qui serre toutes ses démonstrations : c’est que Marcel Duchamp se comporte tel un curator et que, par ses actions diverses, il en a modifié le paradigme. Conservateur de musée, il le serait dès le Grand Verre en s’imposant par le choix des matériaux utilisés afin de lutter contre l’oxydation de la peinture, par cette volonté de documenter l’œuvre en collectant les notes accumulées pour son élaboration (Boîte verte) et par ce souci d’en assurer le suivi en les éditan..
Effects of specific allergen immunotherapy on biological markers and clinical parameters in asthmatic children: a controlled-real life study
No full textAbstract Background Allergen-specific immunotherapy (AIT) is the only treatment able to change the natural course of allergic diseases. We aimed at investigating the clinical efficacy of SLITOR (Serbian registered vaccine for sublingual allergen specific immunotherapy). Methods 7–18 years old children with allergic asthma and rhinitis were enrolled and addressed to the active (AIT plus pharmacological treatment) or control (standard pharmacological treatment only) group. Clinical and medications scores, lung function and exhaled FeNO were measured at baseline and at every follow-up. Results There was a significant improvement in both nasal and asthma symptom scores as well as in medication score in SLIT group. SLIT showed an important influence on lung function and airway inflammation. Conclusions Our data showed that SLITOR was effective not only in terms of patient reported outcomes but an improvement of pulmonary function and decrease of lower airway inflammation were also observed
