Compound conditionals, Fr\'echet-Hoeffding bounds, and Frank t-norms
2021
Abstract In this paper we consider compound conditionals, Frechet-Hoeffding bounds and the probabilistic interpretation of Frank t-norms. By studying the solvability of suitable linear systems, we show under logical independence the sharpness of the Frechet-Hoeffding bounds for the prevision of conjunctions and disjunctions of n conditional events. In addition, we illustrate some details in the case of three conditional events. We study the set of all coherent prevision assessments on a family containing n conditional events and their conjunction, by verifying that it is convex. We discuss the case where the prevision of conjunctions is assessed by Lukasiewicz t-norms and we give explicit s…
Fractal Dimension Logarithmic Differences Method for Low Voltage Series Arc Fault Detection
2021
Series arc faults introduce singularities in the current signal and changes over time. Fractal dimension can be used to characterize the dynamic behaviour of the current signal by providing a degree of signal chaos. This measure of irregularity exhibits changes in signal behaviour that can suitably be used as a basis for series arc fault detection. In this paper, an efficient low voltage series arc fault detection method based on the logarithmic differences of the estimate of the fractal dimension of the current signal using the multiresolution length-based method is presented. The discrete wavelet transform and the hard thresholding denoising with the universal threshold are also used. Exp…
Thermofluid-dynamic assessment of the EU-DEMO divertor single-circuit cooling option
2023
Until 2019, the thermo-hydraulic development of the EU-DEMO divertor was based on the “double-circuit” concept, in which two independent cooling circuits served by two different Primary Heat Transfer Systems were used to cool the Plasma-Facing Components (PFC) and the Cassette Body (CB). During the Divertor Final Design Review Meeting, held in May 2020, the possibility to adopt a single cooling circuit to serve both components was suggested. This new cooling circuit was originally conceived with the aim of simplifying remote maintenance, with potential benefits for some aspects of safety and balance of plant design and integration. During the years from 2020 to 2022, in the fram…
"Table 8" of "First measurement of the quark to photon fragmentation function"
1995
4-JET events. Variable Z has been defined as E(gamma)/(E(gamma)+E(had)), where E(gamma) is the energy of the hard photon in 'photon-jet', E(had) is the energy of the rest hadrons in jet. Ycut is jet resolution parameter (see paper).
EMNCS – LESSONS ON THE WAY TO AN INNOVATION-BASED DEVELOPMENT. EMPIRICAL FINDINGS
2015
The main focus of (the two parts of) this article is on the emerging countries and their development paths. Particularly, it emphasizes on the role and contribution of innovation (of all kinds, in all its forms) for multinational companies from emerging economies (EMNC); the entire research endeavor is placed under the auspices of the knowledge-based society – the one that makes knowledge the ultimate source of power, enabling entities to use and potentially multiply it at the same time at global scale. Analyzing the situation of some emerging economies (starting from their best ranked multinationals), the article draws some empirical and theoretical conclusions on the ways knowledge and in…

Guava (Psidium guajava L.) Leaf Extract as Bioactive Substances for Anti-Androgen and Antioxidant Activities
2022
Leaves of guava (Psidium guajava L.) have been used in Thai folk medicine without any supporting evidence as a traditional herbal remedy for hair loss. Androgenetic alopecia (AGA) is chronic hair loss caused by effects of androgens in those with a genetic predisposition, resulting in hair follicle miniaturization. Our objectives were to provide the mechanistic assessment of guava leaf extract on gene expressions related to the androgen pathway in well-known in vitro models, hair follicle dermal papilla cells (HFDPC), and human prostate cancer cells (DU-145), and to determine its bioactive constituents and antioxidant activities. LC-MS analysis demonstrated that the main components of the et…
The Effect of Nominal Exchange Rate Volatility on Real Macroeconomic Performance in the CEE Countries
2011
Working Paper Gate 09-34; International audience; This paper analyzes the relation between nominal exchange rate volatility and several macroeconomic variables, namely real per output growth, excess credit, foreign direct investment (FDI) and the current account balance, in the Central and Eastern European EU Member States. Using panel estimations for the period between 1995 and 2008, we find that lower exchange rate volatility is associated with higher growth, higher stocks of FDI, higher current account deficits, and higher excess credit. The results are economically and statistically significant, and robust.
Beam test results of IHEP-NDL Low Gain Avalanche Detectors(LGAD)
2020
A High-Granularity Timing Detector (HGTD) is proposed based on the Low-Gain Avalanche Detector (LGAD) for the ATLAS experiment to satisfy the time resolution requirement for the up-coming High Luminosity at LHC (HL-LHC). We report on beam test results for two proto-types LGADs (BV60 and BV170) developed for the HGTD. Such modules were manufactured by the Institute of High Energy Physics (IHEP) of Chinese Academy of Sciences (CAS) collaborated with Novel Device Laboratory (NDL) of the Beijing Normal University. The beam tests were performed with 5 GeV electron beam at DESY. The timing performance of the LGADs was compared to a trigger counter consisting of a quartz bar coupled to a SiPM read…
La aceptación tecnológica de las Apps y su influencia en la co-creación, el engagement y la calidad de la relación: crear valor para el cliente en el…

Impulsada por la acelerada proliferación de las tecnologías de la información y la comunicación, la economía colaborativa ha surgido como una tendencia emergente en el comportamiento del consumidor que cambia la forma en que se proporcionan y consumen los productos y servicios. El propósito de este estudio fue crear y probar un modelo holístico que explique las intención de uso y de co-creación de los usuarios de aplicaciones de entrega de comida a domicilio – FDA en Colombia a partir del contexto de la economía colaborativa. Sobre la base de varios enfoques académicos, este estudio se propuso a partir del Modelo de Aceptación Tecnológica – TAM, la lógica dominante del servicio, la teoría d…
