La aparición del debate postcolonial en América Latina: posiciones, contradicciones y problemas

2010

La aparición de la cuestión postcolonial en los estudios latinoamericanos durante la década de los noventa mostró algunas de las limitaciones del debate sobre la condición postcolonial cuando se aplicaba a contextos históricos diferentes a aquellos en los que había nacido. En las últimas décadas, conceptos como subalternidad, postoccidentalismo o pensamiento fronterizo han sido reconceptualizados para superar dichas limitaciones. En este artículo se trata de detectar las contradicciones y problemas fundamentales de esas aproximaciones.

: une évaluation des perceptions des enseignants

2017

International audience; Le discours des experts et des organisations internationales, de même que les initiatives des politiques et mouvements en faveur de l'émancipation des personnes handicapées sont orientés vers la construction d'une école pour tous (Ainscow et al., 2003 ; Déclaration de Salamanque, 1994 ; Conférence de Dakar, 2000 ; Convention relative aux droits des personnes handicapées, 2006). L'inclusion scolaire implique des modifications et des bouleversements tant dans les pratiques enseignantes que sur le plan de l'organisation scolaire dans son ensemble. Il importe de s'intéresser aux perceptions des enseignants envers la politique nationale visant l'inclusion à l'école ordina…

Approximated overlap error for the evaluation of feature descriptors on 3D scenes

2013

This paper presents a new framework to evaluate feature descriptors on 3D datasets. The proposed method employs the approximated overlap error in order to conform with the reference planar evaluation case of the Oxford dataset based on the overlap error. The method takes into account not only the keypoint centre but also the feature shape and it does not require complex data setups, depth maps or an accurate camera calibration. Only a ground-truth fundamental matrix should be computed, so that the dataset can be freely extended by adding further images. The proposed approach is robust to false positives occurring in the evaluation process, which do not introduce any relevant changes in the …

Reduced Order Models for Pricing European and American Options under Stochastic Volatility and Jump-Diffusion Models

2016

European options can be priced by solving parabolic partial(-integro) differential equations under stochastic volatility and jump-diffusion models like the Heston, Merton, and Bates models. American option prices can be obtained by solving linear complementary problems (LCPs) with the same operators. A finite difference discretization leads to a so-called full order model (FOM). Reduced order models (ROMs) are derived employing proper orthogonal decomposition (POD). The early exercise constraint of American options is enforced by a penalty on subset of grid points. The presented numerical experiments demonstrate that pricing with ROMs can be orders of magnitude faster within a given model p…

Use of wavelet for image processing in smart cameras with low hardware resources

2013

International audience; Images from embedded sensors need digital processing to recover high-quality images and to extract features of a scene. Depending on the properties of the sensor and on the application, the designer fits together different algorithms to process images. In the context of embedded devices, the hardware supporting those applications is very constrained in terms of power consumption and silicon area. Thus, the algorithms have to be compliant with the embedded specifications i.e. reduced computational complexity and low memory requirements. We investigate the opportunity to use the wavelet representation to perform good quality image processing algorithms at a lower compu…

Everyday Appropriations of Information Technology: A Study of Creative Uses of Digital Cameras

2011

Repurposive appropriation is a creative everyday act in which a user invents a novel use for information technology (IT) and adopts it. This study is the first to address its prevalence and predictability in the consumer IT context. In all, 2,379 respondents filled in an online questionnaire on creative uses of digital cameras, such as using them as scanners, periscopes, and storage media. The data reveal that such creative uses are adopted by about half of the users, on average, across different demographic backgrounds. Discovery of a creative use on one's own is slightly more common than is learning it from others. Most users discover the creative uses either completely on their own or wh…

A Case for Raising the Camera: A Driving Simulator Test of Camera-Monitor Systems

2021

Objective This experiment provides a first-of-its-kind driving-simulator study to investigate the feasibility of camera-monitor systems (CMS) with displaced side-mounted cameras in sedans. Background Among the increasing number of studies investigating the replacement of side-mounted rearview mirrors with CMS, the placement of side-mounted cameras has been largely neglected. Moreover, user preferences with respect to camera placement have not been validated in a driving simulator. Past research merely has shown that the vertical camera position can affect distance perception. Method In a driving simulator experiment, we investigated the effects of rearward camera placement on driver accepta…
