Algorithms for coherence checking and propagation of conditional probability bounds
2001
In this paper, we propose some algorithms for the checking of generalized coherence (g-coherence) and for the extension of imprecise conditional probability assessments. Our concept of g-coherence is a generalization of de Finetti’s coherence principle and is equivalent to the ”avoiding uniform loss” property for lower and upper probabilities (a la Walley). By our algorithms we can check the g-coherence of a given imprecise assessment and we can correct it in order to obtain the associated coherent assessment (in the sense of Walley and Williams). Exploiting some properties of the random gain we show how, in the linear systems involved in our algorithms, we can work with a reduced set of va…
Mappings of Lp-integrable distortion: regularity of the inverse
2016
Let be an open set in ℝn and suppose that is a Sobolev homeomorphism. We study the regularity of f–1 under the Lp-integrability assumption on the distortion function Kf. First, if is the unit ball and p > n – 1, then the optimal local modulus of continuity of f–1 is attained by a radially symmetric mapping. We show that this is not the case when p ⩽ n – 1 and n ⩾ 3, and answer a question raised by S. Hencl and P. Koskela. Second, we obtain the optimal integrability results for ∣Df–1∣ in terms of the Lp-integrability assumptions of Kf.
Envelopes for sets and functions II: generalized polarity and conjugacy
2018
International audience; Let X,Y be two nonempty sets, Φ an extended real-valued bivariate coupling function on X × Y and Γ a subset of X × Y. The present paper provides extensions to the well-known generalized Φ-conjugacy and Γ-polarity of diverse results of our previous work [2] related to φ-conjucacy and Λ-polarity, where Λ is a subset of a vector space E and φ is a function on E defining the particular coupling function (x,y)→φ(x−y) on E × E. A particular attention is devoted to the conjugacy functions (resp. polarity sets) which are mutually generating. Finally, for a superadditive conjugacy function Φ, we obtain a full description of the class of Φ-envelopes.
Conceptions of healthcare professionals about rehabilitees’ participation in goal setting in an acute hospital : a phenomenographic study
2022
Purpose: In acute care, effective goal-setting is an essential phase of a successful rehabilitation process. However, professionals’ knowledge and skills in rehabilitee-centered practice may not always match the ways of implementing goal-setting. This study aimed to describe the variation in how acute hospital professionals perceive and comprehend rehabilitee participation in rehabilitation goal-setting. Methods: Data were collected by interviewing 27 multidisciplinary rehabilitation team members in small groups shortly after rehabilitation goal-setting sessions. A qualitative research design based on phenomenography was implemented. Results: We identified four conceptions of rehabilitee pa…
Active disturbance rejection control of linear induction motor
2017
This paper proposes the theoretical framework and the experimental application of the active disturbance rejection control to linear induction motors. Such a nonlinear control (ADRC) technique can be viewed as a particular kind of input-output linearization control, where the nonlinear transformation of the state is not computed by means of the model, but it is estimated online. Such an approach permits to cope with unmodelling dynamics, as well as uncertainty in the knowledge of the model parameters and exogenous disturbances. The effectiveness of the proposed ADRC control law has been verified both by numerical simulations and experimentally on a suitably developed test setup. Moreover, t…
Jet fragmentation transverse momentum distributions in pp and p-Pb collisions at √s, √sNN = 5.02 TeV
2021
Jet fragmentation transverse momentum (jT) distributions are measured in proton-proton (pp) and proton-lead (p-Pb) collisions at √sNN = 5.02 TeV with the ALICE experiment at the LHC. Jets are reconstructed with the ALICE tracking detectors and electromagnetic calorimeter using the anti-kT algorithm with resolution parameter R = 0.4 in the pseudorapidity range |η| < 0.25. The jT values are calculated for charged particles inside a fixed cone with a radius R = 0.4 around the reconstructed jet axis. The measured jT distributions are compared with a variety of parton-shower models. Herwig and Pythia 8 based models describe the data well for the higher jT region, while they underestimate the low…
"We will hunt Merkel": Representations of the German elections 2017 in British and American newspapers
2018
Uutisvälineiden tehtävä on tiedottaa maailman tapahtumista objektiivisesti suurelle yleisölle, mutta usein mediainstituutioiden tavoitteet määrittävät uutisraportoinnin näkökulman. Kielen käytöllä on tärkeä rooli mediadiskursseissa, ja erityisesti representaatioiden luomisessa. Median kuvaukset voivat vaikuttaa yleisön mielipiteeseen aiheista, joihin ihmisillä ei ole kosketusta jokapäiväisessä elämässä. Maan ulkopolitiikka ja väestön mielipide muista maista kuten esimerkiksi Saksasta, joka on johtavassa asemassa Euroopassa, on tärkeä globalisoituneessa maailmassamme. Tämän tutkielman tarkoituksena on tarkastella miten Saksan parlamenttivaaleja 2017 representoidaan brittiläisessä ja amerikka…
Social innovation in a post-conflict setting : examining external factors affecting social service NGOs
2021
While the study of the influence of external environmental factors on non-governmental organizations (NGOs) is well explored in the international development literature, the importance of these factors on NGOs’ transformative roles in a post-conflict development setting remains less understood. Nevertheless, external environmental factors could have a crucial impact on NGOs in such a context, especially when NGOs want to integrate a socially innovative approach into the social services they provide. Using survey data of staff members of social service NGOs from post-conflict Bosnia and Herzegovina (N = 120) and applying resource dependence theory, this study identifies three environmental f…
Nasium : Sondage archéologique à Saint-Amand-sur-Ornain " Le Cul de Breuil "
2010
Ce rapport de fouille présente les résultats d'un sondage archéologique mené au cœur du site de Nasium, à l'interface entre l'oppidum celtique et l'agglomération antique. Le système de voirie qui relie ces deux , dans le prolongement d'une des portes principales de l'oppidum, a été ainsi révélé, associé à des structures à caractère funéraire ou rituel. La chronologie de ces vestiges, centrée sur les dernières décennies du Ier siècle avant J.-C., correspond à la période durant laquelle l'oppidum est abandonné au profit de la plaine alluviale de l'Ornain. Par ailleurs, la découverte de plusieurs centaines de clous de chaussure militaires et de céramiques d'origine italique pose la question du…
Arredi e suppellettili liturgiche in stile neoclassico nella Chiesa Madre di Petralia Sottana
2015
Il contributo, utilizzando documenti inediti, esamina alcune suppellettili liturgiche in stile neoclassico della Chiesa Madre di Petralia Sottana. Tra questi l’ostensorio del 1817 in argento e pietre preziose commissionato dall’arciprete don Antonio Mancusi agli argentieri di Acireale (Ct) Alfio e Salvatore Strano che lo hanno realizzato avvalendosi della collaborazione di Antonino Sirretta e Salvatore Maddalena. Interessante, inoltre, si rivela l’arredo, composto da vasi, candelabri, paliotto, leggio e cornice di cartagloria, tutti in argento e in stile neoclassico, della cappella dedicata alla Vergine Immacolata della stessa Matrice, commissionato grazie alla volontà testamentaria di don …
