Profanación de los cuerpos muertos femeninos
2021
En la historia del arte y de la cultura visual aparecen cuerpos muertos femeninos, habitualmente remarcando su belleza y juventud, sobre los que se ejerce una serie de consideraciones bien distintas a las que merecen los muertos masculinos. Entre ellas la curiosidad científica, el erotismo o la atracción convergen para justificar la exhibición y contemplación de las muertas femeninas. Paralelamente, el imaginario literario ha alimentado mitos sobre el poder que procesaban dichos cuerpos fenecidos en los varones, recalando con el tiempo en los medios de comunicación de masas, especialmente en el cine. Otra vertiente que considerar ha sido la proliferación de fotografías post mortem en donde …
Cruces procesionales y cruces de término. Alcance teológico y social de sus particularidades iconográficas
2018
El reino de Valencia, como otros de la Corona de Aragón y del resto de la Península Ibérica, se mostró especialmente propicio al levantamiento de cruces de término; pero los pocos estudios académicos que les han prestado atención se han detenido en su aspecto estilístico, lo que ha llevado a no pocos investigadores a comparar estas cruces con las de orfebrería. Más allá de su decoración, sin embargo, sus respectivas tipologías iconográficas presentan sustanciales diferencias. La ubicación de las cruces de término, fuera del ámbito eclesiástico, su medio material y, sobre todo, su función, podrían haber determinado las diferencias iconográficas respecto a otras cruces y, por ende, las implic…
O conceito de imagem-presença na arte da idade média
2011
Este artigo propõe situar as principais correntes de leitura da imagem na arte medieval e sublinha a aparição de uma matriz original de pensamento, o pensamento pela arte, entre 1950 e 2000. No centro dessa nova épistémé, afirmou-se o conceito de imagem-presença, discutido a partir de três exemplos de entre o ano mil e c., 1450 e de um diálogo interdisciplinar com a antropologia social e a filosofia das ciências. This article aims to contextualize the main currents in the interpretation of medieval images, underlining to appearance of an original matrix of thought, thinking through art, between 1950 and 2000. At the heart of the new épistémè, the concept of image-presence is put forward and…
iHERITAGE Project : AR/VR for the enhancement and accessibility of the norman architecture of the Unesco site of Palermo
2023
In the context of conservation and dissemination of cultural heritage, noninvasive technologies for the generation of digital models have produced exponential growth in the quality of the data acquired. The digital contents processed allow the use of architectural contexts that no longer exist or sites that are di cult to access, thanks to the visualisation of high-resolution and immersive products. However, the process from acquisition to visualisation requires optimisation strategies and specific operational choices, depending on the design goals. The study describes some results of a broader research within the iHERITAGE Project funded by the ENI CBC MED Program 2014-2020, critically des…
Modes de représentation des trajectoires quotidiennes des habitants
2007
Representing the daily trajectories of individuals Current research on inhabitants' daily mobilities has confirmed that individual mobility strategies are based on activity programmes. In France, the Household Travel Survey (HTS) is one of the principal sources of information about individual travel behaviour. Despite some drawbacks, they are rich sources of spatio-temporal data, as well as providing information on individual and household characteristics. However, for daily mobilities to be analysed, the raw data need to be reorganized. This study is based on the Grenoble-area Household Travel Survey, carried out in 2002. We propose to explore the HTS data through examples of individual mo…
Realism Score for Immersive Virtual Reality Systems and Driving Simulators
2016
International audience; Traditional 2D or 3D quality assessment methods are not sufficient to assess the realism of the outputs of a simulator/immersive virtual reality system. We propose an assessment method based on a scoring system through a new approach. The objective of this paper is to propose a score scale for any simulator or immersive display system that would represent how close to the human visual system the signals that are sent through the display are. Weighted items considered are contrast, acuity, frames per seconds, brightness, field of view and the number of color available.
TBSSvis: Visual Analytics for Temporal Blind Source Separation
2020
Temporal Blind Source Separation (TBSS) is used to obtain the true underlying processes from noisy temporal multivariate data, such as electrocardiograms. TBSS has similarities to Principal Component Analysis (PCA) as it separates the input data into univariate components and is applicable to suitable datasets from various domains, such as medicine, finance, or civil engineering. Despite TBSS’s broad applicability, the involved tasks are not well supported in current tools, which offer only text-based interactions and single static images. Analysts are limited in analyzing and comparing obtained results, which consist of diverse data such as matrices and sets of time series. Additionally, p…
Creating images / Feigning objects. Dialogues between the artistic projects of Isidro Ferrer, Sean Mackaoui & Chema Mado
2013
[EN] As a tribute to the opening of a new exhibition space, the present text traces the common thread that links together three contemporary artists, active in the Spanish context —Chema Madoz, Sean Mackaoui and Isidro Ferrer— tightly linked all of them to visual poetry, from photography, collage and objects. Close existing connections between images and texts, according to the double direction which, on the one hand, creatively relate texts with images (hypotyposis) are also studied and, on the other hand, descriptively linked images with texts (ekphrasis). Both strategies are two fundamental ways for the explanation and interdisciplinary interpretation from the current aesthetics, referri…
Feasibility study of VoIP in 3GPP UMTS release 5 interworking with fixed networks
2003
Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad The Universal Mobile Telecommunications System (UMTS) is denoted as a 3rd generation cellular system and has been designed with the objective to be a system with global coverage. With improvement of bandwidth capabilities, the UMTS system has the ability to support real time multimedia services. The focus in this thesis is Voice over IP (VoIP) which enables a user to make phone calls in the packet switched network in UMTS. This thesis starts with a presentation of VoIP with the quality requirements related to a voice session. A voice conversation needs a guaranteed quality to satisfy the participants…
Wavelet-based video compression: A glimpse of the future?
2004
Masteroppgave i informasjons- og kommunikasjonsteknologi 2004 - Høgskolen i Agder, Grimstad Even though wavelet-based video compression has been an area of research for more than a decade, motion estimation and compensation has been considered complex and inefficient until recently. We have carried out a thorough investigation of existing research work in this field, and found that fundamental problem with wavelet-based temporal removal while obtaining highly scalability (the wavelet-properties of multiresolution structure in combination with embedded coding), has been solved by performing motion compensated temporal filtering within the wavelet domain of a overcomplete three-dimensional li…
