Study of some forms of expression of emotions and feelings in the context of new forms of communication

2018

This thesis focuses on the linguistic expression of feelings and emotions in a corpus until now little questioned in this type of studies, in this case the forms of instantaneous communication made possible by a new technology and that seems predisposed to many expressive markers. It moves the cursor studies on the linguistic expression of these emotional categories of the system to employment, interviewing a corpus formed by four forms of communication: blogs, discussion forums, Facebook and Twitter. The work anchors reflection cognitively seeking to show, in a dynamic perspective, how to build this type of discourse in mediated interaction. It studies the different linguistic and extra-li…

Realistic model of compact VLSI FitzHugh–Nagumo oscillators

2013

In this article, we present a compact analogue VLSI implementation of the FitzHugh–Nagumo neuron model, intended to model large-scale, biologically plausible, oscillator networks. As the model requires a series resistor and a parallel capacitor with the inductor, which is the most complex part of the design, it is possible to greatly simplify the active inductor implementation compared to other implementations of this device as typically found in filters by allowing appreciable, but well modelled, nonidealities. We model and obtain the parameters of the inductor nonideal model as an inductance in series with a parasitic resistor and a second order low-pass filter with a large cut-off freque…

A VLSI for deskewing and fault tolerance in LVDS links

2005

The device presented at this work is a switch implemented in a 0.35 mum CMOS process for compensating the skew which affects parallel data signal transmissions and for providing fault tolerance in large scale scalable systems, for instance used in trigger farms for high energy physics experiments. The SWIFT chip (SWItch for Fault Tolerance) is part of a cluster built around commercially components which has been inspired by the LHCb experiment. The skew is extremely important because it directly affects the sample window available to the receiver logic and either forces to use quality and expensive cables in order to minimize its effects or reduces the maximum signal transmission range or d…

Le marketing tribal électronique: vers une rationalisation sociale généralisée de la socialisation en ligne ?

2010

International audience; L’instrumentalisation marchande du phénomène de socialisation électronique, sans nous questionner plus avant ici sur son efficacité économique réelle, réactualise la question de la rationalisation du lien social à l’heure de la massification d’Internet. Cette rationalisation est considérée par beaucoup de penseurs critiques, à la suite des travaux d’Habermas sur l’Espace Public, comme un affaiblissement, voire une disparition d’un être-ensemble détaché pour partie de la raison calculatoire, de la logique de l’intérêt. Ainsi, les stratégies marketing ciblant la population internaute, que l’on pourrait rassembler en nous inspirant de Bernard Cova et de Michel Maffesoli…

Implementation of green harvesting in the Sicilian wine industry: Effects on the cooperative system

2015

This paper contributes to assessing the effectiveness of the GH measure to contribute in reducing the supply of wine grapes, and thus contrasting the fall of wine prices in those years when especially abundant productions are expected. By analysing the application of this measure to the Sicilian wine sector during the three-year period (2010–2012), we assess its effects on the regional wine cooperative system. The results from the analysis of the statistical data show that the GH measure was successful in terms of the number of applications, the supported area and financial expenditures, and contributed with other factors to determining a reduction in wine grape production. The empirical su…

The IXO Wide-Field Imager

2010

The Wide Field Imager (WFI) of the International X-ray Observatory (IXO) is an X-ray imaging spectrometer based on a large monolithic DePFET (Depleted P-channel Field Effect Transistor) Active Pixel Sensor. Filling an area of 10 × 10 cm² with a format of 1024 × 1024 pixels it will cover a field of view of 18 arcmin. The pixel size of 100 × 100 μm² corresponds to a fivefold oversampling of the telescope's expected 5 arcsec point spread function. The WFI's basic DePFET structure combines the functionalities of sensor and integrated amplifier with nearly Fano-limited energy resolution and high efficiency from 100 eV to 15 keV. The development of dedicated control and amplifier ASICs allows for…

The Wide Field Imager (WFI) is one of the two instruments of the ATHENA astrophysics space mission approved by ESA as the second large mission in the Cosmic Vision 2015-2025 Science Programme. The WFI, based on a large array of depleted field effect transistors (DEPFET), will provide imaging in the 0.2-15 keV band over a 40'x40' field of view, simultaneously with spectrally an…

A 1.3 megapixel FPGA-based smart camera for high dynamic range real time video

2013

International audience; A camera is able to capture only a part of a high dynamic range scene information. The same scene can be fully perceived by the human visual system. This is true especially for real scenes where the difference in light intensity between the dark areas and bright areas is high. The imaging technique which can overcome this problem is called HDR (High Dynamic Range). It produces images from a set of multiple LDR images (Low Dynamic Range), captured with different exposure times. This technique appears as one of the most appropriate and a cheap solution to enhance the dynamic range of captured environments. We developed an FPGA-based smart camera that produces a HDR liv…
