Approximate localisation of imperfections in fixed domain
No full textNiniejsza praca przedstawia procedurę przybliżonego wyznaczania loka-lizacji uszkodzenia w zadanym obszarze. Definiujemy problem spektralny, którego roz-wiązaniami są wartości własne. Wartości te zależą od położenia i wielkości uszkodzenia.Głównym celem postawionym w pracy jest rozwiązanie zadania odwrotnego, które polegana lokalizowaniu uszkodzenia obszaru na podstawie wektora wartości własnych. Z uwagi nabrak jednoznaczności rozwiązań definiujemy nowe zadanie w innym obszarze, dla któregozagwarantowane jest istnienie przybliżonego rozwiązania zadania odwrotnego.W celu wyznaczenia lokalizacji uszkodzenia definiujemy nowe odwzorowanie, którymjest warunkowa wartość oczekiwana położenia uszkodzenia pod warunkiem, że znamyskończony ciąg wartości własnych. Odwzorowanie to jest aproksymowane przez tak zwanyciąg aproksymujący, którym jest rodzina sieci neuronowych Elmana. Sieć jest budowanaw sposób dynamiczny. Jej wielkość jest zależna od liczby elementów należących do zbioruuczącego. Stosowana metoda aproksymacji jest zbieżna.Słowa kluczowe: Sieci neuronowe, Wartości własne, Aproksymacja, Warunkowa wartośćoczekiwana.In this paper we present a procedure for determining the approximate locationof imperfection in a fixed domain. We define the spectral problem whose solutions areeigenvalues. These values depend on the location and the size of the imperfection. Themain aim in this work is to find the solution of the inverse problem. It means that we findthe location of the imperfection in our domain based on the vector of eigenvalues. For theinverse problem we don’t have the uniqueness of the solutions so we Define a new problemin new domain.For the new problem we obtain the existence of the approximate solution of the inverseproblem. In order to determine the location of imperfection we define a new mapping.This mapping is defined as the conditional expectation of the location of imperfection,provided that we know the finite number of eigenvalues. The mapping is approximated bythe Elman’s neural networks. The networks are built in a dynamic way. Their size dependson the size of the learning set. The approximation method is convergent.Keywords: Neural networks, Eigenvalues, Approximation, Conditonal expectation
Stages for the More Sustainable Farm
Full text linkCurrently, agricultural farm units are faced with a double and most times contradictory challenge, in order to be successful: on the one hand the invested capital has to be profitable and the economic performance has to be maximised. On the other hand, given the socio-environmental situation, it is necessary to preserve and to protect the environment and natural resources. Given the potential conflict of the two aims, since the satisfaction of one implies the underperformance of the other (and vice versa), the question then is: which is the solution to choose? We intend, in this work, to formulate a farm plan with the purpose of reconciling the criteria of environmental sustainability with that of economic competitiveness. For this achievement we proceed to the comparative study of sustainability of different groups of farms identified in the study area (first evaluation cycle) through MESMIS (“Marco para la Evaluación de Sistemas de Manejo de Recursos Naturales Mediante Indicadores de Sustentabilidad” - Framework for Evaluation of Natural-Resource Systems Handling through Sustainability Indicators) methodology, that allowed to select the more sustainable group of farms. Based on the found potentialities and weakness on these production systems, we stepped to the planning of a production unit of bovine meat, which obeys simultaneously to economic and environmental objectives, using Multicriteria Decision. We finished the work with the sustainability evaluation between groups of farms identified previously and the planned farms (second evaluation cycle), based, again, in the MESMIS methodology, to confirm (or not) the greatest sustainability of the last ones. Analyses of the results allow us to confirm the greatest relative sustainability of the planned farm, for the diverse traced scenarios.Decision taking, planning, sustainability, Environmental Economics and Policy, Farm Management,

In 2009, she was awarded the Premio Scenario per Ustica for E bello vivere liberi!, first show of a trilogy on female resistance, followed by La semplicità ingannata (2012) and Sorry, boys (2015). These three texts are published in Resistenze femminili (Udine: Forum, 2019). In 2018 she created Il canto della caduta. Earthbound (2021) is her last devised show, which brings in the themes of ecofeminism, taking cues from the theories of Donna Haraway and Bruno Latour. In 2021 she became associate artist at the Piccolo Teatro in Milan. In 2023, she is guest of honor at the 11th Biennale internationale des arts de la marionette in Paris. She was awarded the prizes Rete Critica (2017), Premio della Critica – ANCT (2018) and Premio Hystrio - Altre Muse (2019).Animation de la discussion avec Marta Cuscunà, performeuse, metteuse en scène, marionnettiste et autrice italienne.

Marta Fraenkel Collection 1890-1968 Bulk dates: 1945-1950
No full textThe Marta Fraenkel Collection holds the papers of the German physician Marta Fraenkel. Particularly prominent in this collection is its family correspondence.Other papers include personal, official, and educational papers, short writings of family members, family trees and postcards. Correspondence of family members, especially that which was sent to Marta Fraenkel, will be found in the first three series of this collection. Series I contains several folders of letters sent to her, including several from her aunt Else Epstein. A number of these letters are also from friends, acquaintances and former colleagues still in Germany, but they all date from the years just following World War II. These letters, especially those of her aunt, describe conditions in occupied Germany and relate their experiences and losses during the war. A number of such letters are from unidentified individuals. Series II also contains an assortment of letters sent by Marta Fraenkel's brother Ernst, including one folder of letters he sent to her. His letters also date from the late 1940s and were all sent while he worked at the U.S. mission in Seoul, Korea. They include many typed circular letters. Ernst Fraenkel's letters clearly convey the experiences of himself and his wife Hanna while in Korea. Particularly prominent is a detailed sixteen-page letter that describes the first days of the Korean War and the evacuation of American personnel from Korea.The following individuals are mentioned in this collection:Berman, William; Bethe, Hans; Brill, Norman; Edinger, Tilly; Epstein, Else; Epstein, Josef; Francken-Schwann, Hans Georg; Geller, Else; Guminski, Jan; Klemperer, Ralph; Löwenthal, Ernst G.; Metzger, Ernst; Möllering, Leonie; Müller, Ernst; Sander, Arnold; Wachenheim, Hedwig; Zwingenberg, M.Marta Fraenkel was born in Cologne on September 19, 1896, the daughter of Georg and Therese (née Epstein) Fraenkel. Following the death of their parents, she and her younger brother Ernst went to live with their maternal uncle Josef Epstein in Frankfurt am Main, where they completed their educations. Her brother Ernst would later become a lawyer, author and political scientist.Marta Fraenkel studied medicine in Bonn and Frankfurt, receiving her medical degree from the University of Frankfurt in 1923. Following her studies she entered public service, holding various positions in research, advisement and consulting capacities. From 1924-1927 she worked as scientific secretary at the GeSoLei (Große Ausstellung für Gesundheitspflege, soziale Fürsorge und Leibesübungen) in Düsseldorf in 1926. From 1928-1933 she was director of the Deutsches Hygiene-Museum in Dresden. While in Dresden she met the editor of the Dresdner Neueste Nachrichten, Theodor Schulz. In 1931 they married; four years later they divorced.In 1935 Marta Fraenkel left Germany for Brussels, where she worked at the National Belgian Cancer League (Ligue nationale Belge centre le Cancer) until her immigration to New York City in 1938. There she worked in various capacities, including for the Welfare Council from 1938-1944. She lived briefly in Washington, D.C. and was a medical advisor for the Social Security administration there from 1944-1947.
