First measurement of proton's charge form factor at very low $Q^2$ with initial state radiation

2017

We report on a new experimental method based on initial-state radiation (ISR) in e-p scattering, in which the radiative tail of the elastic e-p peak contains information on the proton charge form factor ($G_E^p$) at extremely small $Q^2$. The ISR technique was validated in a dedicated experiment using the spectrometers of the A1-Collaboration at the Mainz Microtron (MAMI). This provided first measurements of $G_E^p$ for $0.001\leq Q^2\leq 0.004 (GeV/c)^2$.

Normal pressures and frictional tractions on shallow conical hopper walls after concentric filling: Predictions and experiments

2013

Author's version of an article in the journal: Chemical Engineering Science. Also available from the publisher at: http://dx.doi.org/10.1016/j.ces.2012.11.028 A silo with a shallow hopper is designed to achieve the required silo capacity when the headroom available is limited, provided that the issue of segregation of stored particulate solids is not a problem. Several analytical models have been proposed to try to predict the design loads for such shallow silo hoppers to guarantee their structural integrity. In this study, a novel finite element analysis has been conducted to explore the development of pressures and tractions on the wall of a full scale shallow hopper when it is filled wit…

Overview of ghost correction for HDR video stream generation

2015

International audience; Most digital cameras use low dynamic range image sensors, these LDR sensors can capture only a limited luminance dynamic range of the scene[1], to about two orders of magnitude (about 256 to 1024 levels). However, the dynamic range of real-world scenes varies over several orders of magnitude (10.000 levels). To overcome this limitation, several methods exist for creating high dynamic range (HDR) image (expensive method uses dedicated HDR image sensor and low-cost solutions using a conventional LDR image sensor). Large number of low-cost solutions applies a temporal exposure bracketing. The HDR image may be constructed with a HDR standard method (an additional step ca…

Progetto professionale e soft skills negli studenti liceali

2020

In questo contributo si descrivono, in primo luogo, le metodologie educative utilizzate in alcune ricerche italiane negli ultimi venti anni per aiutare gli studenti del liceo a costruire il loro progetto di vita formativo-professionale; in secondo luogo, si presentano le fasi e i risultati della prima parte di una ricerca-intervento sull’orientamento dal liceo all’università svolta nella città di Palermo nell’anno scolastico 2018-2019; in terzo luogo, si espongono le tre attività formative (sessioni di scrittura espressiva, colloqui di orientamento e laboratori interdisciplinari Scuola-Università) previste durante la seconda annualità per consentire ai liceali di saggiare i loro interessi d…

Aborted quantitative study in the French music industry: the changes of music labels facing streaming

2020

International audience; This paper shows a failed case study of the impact of streaming on labels’ life through the exploitation of three quantitative databases. Streaming is a major external change for the music consumption and music producers. As labels are dealing with both producers and consumers, they may have been hardly impacted by this change. Yet there was a need to identify the changes that streaming brought and its impact for the organizations that decided not to adopt it. The ecology of population framework and the death vs dynamism dyad was supposed to give a clear reading of this phenomenon. In order to identify labels that did not adopt streaming, three databases were tested,…

Using eye-movement modelling examples to improve critical reading of multiple webpages on a conflicting topic

2022

This project investigates the effects of an EMME intervention on undergraduates' sourcing when reading conflicting multiple texts on the Internet. Dependent variables: eye-movements on SERP, webs header, texts authors, and texts; use of source information in summaries; ideas from texts in summaries.

Professional vision in the classroom: Teachers’ knowledge-based reasoning explaining their visual focus of attention to students

2023

This study investigated Grade 2 teachers' (N = 50) professional vision through eye-tracking methodology and retrospective think-aloud interviews. The study examined the extent to which teachers' knowledge-based reasoning explains their visual focus of attention to whole class and individual students. We found that teachers' descriptions of students' social relations and emotions associated positively with teachers' visual focus of attention to the whole class. Teachers' descriptions of teacher-related information/elaboration and pedagogy linked negatively with teachers' visual focus of attention to individual students. The findings suggest that teachers' visual focus of attention to student…

Experiences from the Use of an Eye-Tracking System in the Wild

2010

Eye-tracking systems have been widely used as a data collection method in the human–computer interaction research field. Eyetracking has typically been applied in stationary environments to evaluate the usability of desktop applications. In the mobile context, user studies with eye-tracking are far more infrequent. In this paper, we report our findings from user tests performed with an eye-tracking system in a forest environment. We present some of the most relevant issues that should be considered when planning a mobile study in the wild using eye-tracking as a data collection method. One of the most challenging finding was the difficulty in identifying where the user actually looked in th…
