    A Parallel Simulator of Quench in Superconducting Magnets

    No full text
    In a superconducting magnet the null resistivity of the cable allows to run a very intense electrical current without dissipating heat. During operation, a region of the superconducting wire can turn to normal state (quench) with possible damage due to intense heat dissipation. Quench simulation is thus a necessary step during magnet design; it is a multi-physics computational problem that ends up very easily with tens of millions of equations in as many unknowns. In this paper we attempt an HPC approach for quench simulation

    Hermann Kant. Ein bio- bibliografisches Profil

    No full text
    The proximity to the power apparatus has cast dark shadows on the literary work of Hermann Kant, who is regarded as one of the most read authors of the GDR. Valerio Furneri embeds Kant's life and work in the all-German context of the 20th century and reinterprets his classics such as Die Aula or Der Aufenthalt. The author does not pursue the claim to rehabilitate the GDR, nor to trivialise Kant's role in it. Instead, the attempt is made to look at Kant's entire work from a temporal distance and to re-evaluate it. Through his works, Kant was able to accompany and depict not only the German-German history, but also European history.Die Nähe zum Machtapparat hat dunkle Schatten auf das literarische Werk von Hermann Kant, der als meistgelesener Schriftsteller der DDR gilt, geworfen. Valerio Furneri bettet Kants Leben und Werk in den gesamtdeutschen Kontext des 20. Jahrhunderts ein und interpretiert vor diesem Hintergrund Klassiker wie Die Aula oder Der Aufenthalt neu. Der Autor verfolgt dabei weder den Anspruch, die DDR zu rehabilitieren, noch Kants Rolle darin kleinzureden. Stattdessen wird der Versuch unternommen, Kants Gesamtwerk aus zeitlicher Distanz zu betrachten und neu zu bewerten. Durch seine Werke gelang es Kant nämlich nicht nur die deutsch-deutsche, sondern auch die europäische Geschichte zu begleiten und abzubilden

    Space Safety and Human Performance

    No full text
    Space Safety and Human Performance provides a comprehensive reference for engineers and technical managers within aerospace and high technology companies, space agencies, operators, and consulting firms. The book draws upon the expertise of the world’s leading experts in the field and focuses primarily on humans in spaceflight, but also covers operators of control centers on the ground and behavior aspects of complex organizations, thus addressing the entire spectrum of space actors. During spaceflight, human performance can be deeply affected by physical, psychological and psychosocial stressors. Strict selection, intensive training and adequate operational rules are used to fight performance degradation and prepare individuals and teams to effectively manage systems failures and challenging emergencies. The book is endorsed by the International Association for the Advancement of Space Safety (IAASS)

    The Limits of Space Radiation Magnetic Shielding: An Updated Analysis

    No full text
    A major problem of long-duration manned missions in the deep space is the flow of high energy charged particles of solar (SPE) and galactic (GCR) origin. SPE has short duration but can be extremely intense and can lead to acute, even lethal, effects. GCR flow is much less intense but is continuous, isotropic, and more energetic; it increases the risk of carcinogenesis and can affect the nervous and cardiovascular systems, restricting the endurance of missions to few months. It is commonly believed that the problem of space radiation can be solved by surrounding the spacecraft habitats with large superconducting magnets, even though a considerable technological effort would be required. However, magnetic shielding has several basic limitations, which restrict the reduction of the radiation dose: they range from the biological effect of the particles in the high region of the GCR spectrum, higher than the shield cutoff energy, to the generation of secondary particles due to the interaction of cosmic rays with magnet and spacecraft materials. The physical and technological constraints of space radiation magnetic shields are discussed in this paper. Despite such limitations, a superconducting magnet could completely eliminate the risk due to SPE. Moreover, it could reduce the GCR adsorbed dose enough to make acceptable the risk of developing long term diseases after a return trip to Mars

    The intentionality of matter: the personal character of nature in Edith Stein's "Potency and act"

    No full text
    In the closing chapter, Francesco Valerio Tommasi elaborates upon the analogy between person and nature in Stein. As he emphasizes, Stein attributes to nature an objectively spiritual dimension, a hidden form of intentionality. As the author suggests, for Stein nature turns out to be a living sign of the spirit—thus, a sign expressing spiritual values, such as emotions. This perspective is present in both the lectures on The Constitution of the Human Person and Potency and Act: the phenomenological reflection on personhood is combined, Tommasi argues, with a Thomist view that brings Stein to conceiving the life of the entire cosmos as a spirit (or act) informing it and shaping it into a living sign of the creation

    Proceedings of the LREC 2020 workshop on Resources and Techniques for User and Author Profiling in Abusive Language (ResT-UP 2020)

    This volume documents the Proceedings of the 1st Workshop on Resources and Techniques for User and Author Profiling in Abusive Language (ResT-UP), held online on 12 May 2020 as part of the LREC 2020 conference (International Conference on Language Resources and Evaluation). The workshop aimed at bringing together researchers and scholars working on author profiling and automatic detection of abusive language on the Web, e.g., cyberbullying or hate speech, with a twofold objective: improving the existing LRs, e.g., datasets, corpora, lexicons, and sharing ideas on stylometry techniques and features needed for profile information extraction and classification. ResT-UP targeted Profiling scholars and research groups, experts in Statistic and Stylistic Analysis of texts as well as computational linguists who investigate author profile and personality both in short texts (social media posts, blog texts and email) and in long texts (such as pamphlets, (fake) news and political documents). ReST-UP represented an opportunity to share profiling experiments with the scientific community and to show automatic detection techniques of abusive language on the Web. Despite the cancellation of LREC 2020 due to the COVID-19 international emergency, ResT-UP was organized online on Microsoft Teams on May 12th 2020 and the programme included three oral presentations and featured an invited talk by Paolo Rosso. ResT-UP was attended by about fifty representatives of academic and industrial organisations

    Welcome to Hell. Dante’s “Inferno” in Valerio Evangelisti’s Eymerich Cycle

    No full text
    The paper examines how Valerio Evangelisti took inspiration from Dante’s Inferno for his Eymerich saga. Evangelisti considers the Middle Ages a mirror of the present and depicts history as a complex system of interrelated events and characters which are mutually linked. In creating a medieval atmosphere which is synchronous with other eras, the author often evokes images and characters from Dante’s Inferno.Nell’articolo si mostra come Valerio Evangelisti si sia ispirato all’Inferno di Dante nella scrittura della sua saga di Eymerich. Evangelisti considera il Medioevo alla stregua di uno specchio del presente, e raffigura la storia come un sistema complesso di eventi interrelati e di personaggi reciprocamente legati l’uno all’altro. Nel creare un’atmosfera medievale che si presenta sincrona rispetto ad altre epoche, Evangelisti evoca soprattutto immagini e personaggi dell’Inferno dantesco
