El uso de materiales didácticos online destinados a la preparación del nuevo examen informatizado «CBFCE»
2010
[ES] A comienzos del año 2010 se hizo oficial la aparición del Computer-based First Certificate in English Examination (CBFCE), la versión informatizada del examen oficial de nivel B2 de Cambridge First Certificate in English (FCE). Este examen, que evalúa las destrezas de aquellos candidatos que desean certificar el estar en posesión de un nivel de inglés intermedio-alto, venía realizándose desde hacía varias décadas en el formato tradicional impreso. No obstante, las exigencias actuales de la sociedad global de la comunicación, en que proporcionar la máxima eficiencia y efectividad es condición sine qua non, han motivado el que esta prestigiosa prueba adopte el formato informatizado, haci…
Suomalaiset nuoret verkkolehtien kuluttajina
2017
Digitalisaatio on muuttanut rajusti perinteistä lehdistöä sekä sisällöntuottami-sen ja jakelukanavien muuttumisen että uusien alan kilpailijoiden myötä. Samaan aikaan digitalisaation mahdollistamat muut ajanviettotavat ovat vähentäneet lukemista vapaa-ajalla, ja postmoderni, saturoitunut kulutusyhteiskunta on muuttanut kuluttajien arvomaailmaa ja kulutuskäyttäytymistä. Tämän tutkielman tarkoituksena oli selvittää nuorten kuluttajien asenteita verkkolehdistön tuotteisiin. Digitaaliajalla moniarvoiseen kulutusyhteiskuntaan syntyneet diginatiivit ovat tulevaisuuden kuluttajia. Heidän asenteidensa ja ostoaikeidensa tunteminen on tärkeää kehitettäessä digitaalisia tuotteita ja palveluita. Tutkie…
Complex dynamics, hidden attractors and continuous approximation of a fractional-order hyperchaotic PWC system
2018
In this paper, a continuous approximation to studying a class of PWC systems of fractionalorder is presented. Some known results of set-valued analysis and differential inclusions are utilized. The example of a hyperchaotic PWC system of fractional order is analyzed. It is found that without equilibria, the system has hidden attractors.
MR3631681 Reviewed Nigsch, E. A.(A-WIENM) On a nonlinear Peetre's theorem in full Colombeau algebras. (English summary) Comment. Math. Univ. Carolin.…
2017
Colombeau algebras are defined as quotients of spaces containing the representatives of generalized functions given by smooth mappings: R:C∞(Ω,D(Ω))→C∞(Ω), where Ω is an open subset of Rn. In this paper the notion of locality defined by the author for a representative R of a nonlinear generalized function is characterized in such a way that the representative depends only on its ∞-jet. Finally, the author examines the possibility of defining a notion of order for the mapping R.
On a Robin (p,q)-equation with a logistic reaction
2019
We consider a nonlinear nonhomogeneous Robin equation driven by the sum of a \(p\)-Laplacian and of a \(q\)-Laplacian (\((p,q)\)-equation) plus an indefinite potential term and a parametric reaction of logistic type (superdiffusive case). We prove a bifurcation-type result describing the changes in the set of positive solutions as the parameter \(\lambda \gt 0\) varies. Also, we show that for every admissible parameter \(\lambda \gt 0\), the problem admits a smallest positive solution.
Computation of lock-in range for classic PLL with lead-lag filter and impulse signals
2016
For a classic PLL with square waveform signals and lead-lag filter for all possible parameters lock-in range is computed and corresponding diagrams are given. peerReviewed
Hold-in, Pull-in and Lock-in Ranges for Phase-locked Loop with Tangential Characteristic of the Phase Detector
2019
In the present paper the phase-locked loop (PLL), an electric circuit widely used in telecommunications and computer architectures is considered. A new modification of the PLL with tangential phase detector characteristic and active proportionally-integrating (PI) filter is introduced. Hold-in, pull-in and lock-in ranges for given circuit are studied rigorously. It is shown that lock-in range of the new PLL model is infinite, compared to the finite lock-in range of the classical PLL. peerReviewed
Forme resilienti della convivialità durante il lockdown
2021
International audience; Il contributo si propone di cogliere le spinte tensive della convivialità durante il lockdown, sia sotto il profilo drammaturgico delle pratiche del quotidiano sconvolte dal Covid-19 sia nel quadra euristico dell tensività che restituisce la dinamica del campo tra le forme de conviviali : dallo stare a tavola alla conviviate sociale "tout court". Una volta stabilito questo quadro, l'isotopia alimentare sarà mantenuta comme forma grammatica attraverso due registri figurativi in particolare : la convivialità intra-familiale, riconfigurata durante la reclusione, e la convivialità online, altra forma resiliente, con aperativi virtuali, collegamenti solidali online e form…
Whispering Gallery Modes: Advanced Photonic Applications
2019
Los micro-resonadores basados en Whispering Gallery Modes (WGMs) han atraido un gran interés en las últimas décadas debido a su fuerte confinamiento de la luz. Tales micro-resonadores pueden ser fabricados con diferentes geometrías y materiales. Estos micro-resonadores exhiben factores de calidad Q altos y volúmenes modales pequeños, lo que permite realizar un gran número de estudios y aplicaciones, como por ejemplo el estudio de efectos no-lineales ópticos. La delgada anchura spectral que presentan las resonancias WGM permite la medida de pequeñas perturbaciones de los parámetros de los micro-resonadores, con un límite de detección bajo. Esta tesis proporciona la caracterización experiment…
The Role of Reputation on Trust and Loyalty : A Cross-Cultural Analysis of Tablet E-Tailing
2018
The purpose of this article is to empirically examine the role of online retailer's website reputation on tablet commerce and to compare the trust arbitration between reputation and loyalty in two cultures - Finland and Nigeria. Data was collected from Finland and Nigeria, using purposive and snowball sampling methods. This article uses Structural Equation Modelling and mediation analysis. The results reveal that the reputation of online retailer's website is not a direct determinant of loyalty for online shopping while trust colligates with ease of use. The effect of an online retailer's website reputation is stronger in Nigeria than in Finland and trust is a strong predictor of ease of us…
