Comparative analysis of acoustic emission signals generated by electrical discharges measured by the hydrophone and the wideband contact transducer
2005
The paper presents a comparative analysis of the acoustic emission (AE) pulses and signals generated by PDs. For this purpose the measurements of the acoustic emission signals generated by PDs were taken in the multipoint-plane system using a hydrophone placed directly in the area of discharge generation, and the AE pulses using a piezoelectric contact transducer which was on a side wall of a power transformer tub. Next, time runs and amplitude density spectra were drawn. Also the descriptors describing signals in the frequency domain were determined and the time-frequency analysis was carried out, which determined spectrograms for the energy density spectrum.

L’école à la maison, quelles leçons sociologiques ?
2020
International audience; S’appuyant sur les résultats de ses propres recherches et d’études portant sur les inégalités sociales et les disparités familiales en termes de suivi scolaire et style éducatif, la sociologue Marie Duru-Bellat propose une première analyse des conséquences possibles de cette période d’« école à la maison ».
Investigating the level of significance of the coherence function in cardiovascular variability analysis
2002
Although the presence of significant coupling between cardiovascular variability series is usually verified according to the threshold value of 0.5 in the coherence function (CF), spectral estimator parameters should also be considered. In this study, the surrogate data technique was introduced to define the level of significance of the CF. The proposed method determined a frequency-dependent threshold over which the hypothesis of zero coherence was rejected. The weighted covariance method and the autoregressive method were used to estimate the CF on simulated series with different degrees of linear coupling and on real cardiovascular data. The threshold was dependent on the type and parame…
The Navier–Stokes equations in exterior Lipschitz domains: L -theory
2020
Abstract We show that the Stokes operator defined on L σ p ( Ω ) for an exterior Lipschitz domain Ω ⊂ R n ( n ≥ 3 ) admits maximal regularity provided that p satisfies | 1 / p − 1 / 2 | 1 / ( 2 n ) + e for some e > 0 . In particular, we prove that the negative of the Stokes operator generates a bounded analytic semigroup on L σ p ( Ω ) for such p. In addition, L p - L q -mapping properties of the Stokes semigroup and its gradient with optimal decay estimates are obtained. This enables us to prove the existence of mild solutions to the Navier–Stokes equations in the critical space L ∞ ( 0 , T ; L σ 3 ( Ω ) ) (locally in time and globally in time for small initial data).
Découverte d'un ex-voto particulier sur le site cultuel d'Essarois (Côte-d'Or) : un cas de polydactylie chez les Gallo-Romains ?
2011
During geo-archaeological research on the slope where the source associated with the Essarois (Côte-d'Or) cult site is located, in the locality of La Cave, an anatomic votive offering of a human foot was discovered in the alluvial sedimentary deposits. Carved from local oolitic limestone, it is rather crude in appearance but it is possible to make out that it has the unusual number of six toes. Although it may have been a blunder or the result of negligence by the sculptor, the phenomenon may equally have been a deliberate representation of a case of polydactyly, a malformation that was known in Antiquity.

I Vaticana fragmenta a due secoli dalla riscoperta
2022
Two centuries have passed since the palimpsest that transmits a Roman legal work known as the Vaticana fragmenta was rediscovered by Angelo Mai in the Vatican Apostolic Library in Rome. This paper reviews the main issues relating to this work and suggests some reasons why a new edition of the text is desirable. 1820 hat Angelo Mai in der Vatikanischen Apostolischen Bibliothek in Rom ein Palimpsest wiederentdeckt, welches ein römisches Rechtswerk – die so genannte Vaticana Fragmenta – überliefert. 200 Jahre sind seitdem genau vergangen. Dieser Beitrag gibt einen Überblick über die wichtigsten Aspekte dieses Werks und zeigt Gründe auf, warum eine neue Ausgabe dieses Textes wünschenswert ist.
Angiotensin Receptor Neprilysin Inhibition Compared With Enalapril on the Risk of Clinical Progression in Surviving Patients With Heart Failure
2015
Background— Clinical trials in heart failure have focused on the improvement in symptoms or decreases in the risk of death and other cardiovascular events. Little is known about the effect of drugs on the risk of clinical deterioration in surviving patients. Methods and Results— We compared the angiotensin-neprilysin inhibitor LCZ696 (400 mg daily) with the angiotensin-converting enzyme inhibitor enalapril (20 mg daily) in 8399 patients with heart failure and reduced ejection fraction in a double-blind trial. The analyses focused on prespecified measures of nonfatal clinical deterioration. In comparison with the enalapril group, fewer LCZ696-treated patients required intensification of med…
