METHODOLOGY OF RECONSTRUCTING THE COGNITIVE FRAME OF THE CONCEPT TOLERANCJA BASED ON THE FRAME SEMANTICS MODEL BY ALEXANDER ZIEM
No full textThe principal aim of this article is to present the author’s own analysis model
for the creation of a holistic cognitive definition of ‘tolerance’, based on Alexander Ziem’s
semantic frame theory. Starting with frame and its constituent elements (slots, fillers,
default values), the author compares her own concept and Ziem’s model, demonstrating
both similarities and differences that can be explained by various aims of the analysis.
The last part discusses the advantages of the frame semantics perspective in the research,
including contrastive research concerning the meaning of linguistic expressions
New Stationary Frame Control Scheme for Three Phase PWM Rectifiers Under Unbalanced Voltage Dips Conditions
Get PDFA new stationary frame control scheme for three-phase pulsewidth-modulation (PWM) rectifiers operating under unbalanced voltage dips conditions is proposed in this paper. The proposed control scheme regulates the instantaneous active power at the converter poles to minimize the harmonics of the input currents and the output voltage ripple. This paper's novelty is the development of a new current-reference generator implemented directly in stationary reference frame. This allows using proportional sinusoidal signal integrator (P-SSI) controllers for simultaneous compensation of both positive and negative current sequence components. No phase-locked loop (PLL) strategies and coordinate transformations are needed for the proposed current-reference generator. Experimental results are presented for a 20-kV A alternative current (ac)/direct current (dc) converter prototype to demonstrate the effectiveness of the proposed control scheme. A comparison with two other existing control techniques is also performed. Fast dynamic performance with small dc-link voltage ripple and input sinusoidal currents are obtained with this control scheme, even under severe voltage dips operating condition
The Lightweight Design of a Dump Truck Frame based on Dynamic Responses
No full textThis paper develops a new scheme for the
lightweight design of heavy dump truck frames based on the
characteristics of dynamic responses. The dynamic response
is predicted using a finite element (FE) model which is
verified by an experimental mode analysis. The FE model is
then used to investigate the characteristics of dynamic
responses and frame weight changes with respect to the
mass changes of each frame component for selecting
significant components. An optimization is finally developed
for the lightweight design under constrains that maintain
required dynamic responses and static strength. The
optimization results show that the weight of frame can be
reduced by 8%, showing that the scheme is an effective way
to achieve automotive lightweight design
Alexander FRAME (2013), Communication et interculturalité : cultures et interactions interpersonnelles
No full textCet ouvrage nous amène au cœur de l’interaction interpersonnelle et explore les processus de co-construction de sens qui caractérisent les relations. L’auteur situe sa réflexion dans les contextes multiculturels, où la culture est définie de façon très large ; chaque individu appartient à de multiples groupes culturels (national et autres) et est donc confronté à l’expérience d’interculturalité lors de la rencontre interpersonnelle. Dans ce livre, Alexander Frame explore les enjeux à la fois ..

Citizen Participation and Political Communication in a Digital World
No full textInternational audienceThe arrival of the participatory web 2.0 has been hailed by many as a media revolution, bringing with it new tools and possibilities for direct political action. Through specialised online platforms, mainstream social media or blogs, citizens in many countries are increasingly seeking to have their voices heard online, whether it is to lobby, to support or to complain about their elected representatives. Politicians, too, are adopting "new media" in specific ways, though they are often criticised for failing to seize the full potential of online tools to enter into dialogue with their electorates. Bringing together perspectives from around the world, this volume examines emerging forms of citizen participation in the face of the evolving logics of political communication, and provides a unique and original focus on the gap which exists between political uses of digital media by the politicians and by the people they represent
