Les restes animaux de la nécropole de Povegliano-Ortaia (IIe-Ier siècle avant notre ère)
2012
International audience; Plus d'un millier de restes animaux ont été recueillis dans vingt-deux inhumations, dix-sept crémations et six sépultures au rite indéterminé. Deux espèces se distinguent par leur fréquence, le porc et la volaille. Le bœuf et les caprinés sont moins fréquents, alors que le cheval, le chien, l'oie et l'ours sont rares. La plupart des porcs sont très jeunes, avec notamment des sujets périnataux. Ils sont souvent déposés sous forme d'épaules, de jambons ou de séries de côtes. La volaille est souvent représentée par des squelettes, tous les sujets dont le sexe a pu être déterminé sont des poules, la plupart adultes.Dans les incinérations, le porc (80 %) et la volaille (1…
A Performance Evaluation of Fusion Techniques for Spatio-Temporal Saliency Detection in Dynamic Scenes
2013
International audience; Visual saliency is an important research topic in computer vision applications, which helps to focus on regions of interest instead of processing the whole image. Detecting visual saliency in still images has been widely addressed in literature. However, visual saliency detection in videos is more complicated due to additional temporal information. A spatio-temporal saliency map is usually obtained by the fusion of a static saliency map and a dynamic saliency map. The way both maps are fused plays a critical role in the accuracy of the spatio-temporal saliency map. In this paper, we evaluate the performances of different fusion techniques on a large and diverse datas…
How cyber breeds crime and criminals
2014
Understanding how cyber breeds novel crime and new criminals is a contribution to criminological models with significant applied value. It is highly important for law enforcement and particularly pivotal for preventive intervention. In this paper we propose a human rights-based crime definition, present explanatory models for cybercrime, and outline future arenas and drivers to suggest to the stakeholder community prevention focuses and priorities. The presented work ultimately aims towards supporting two crime preventive design initiatives, one targeted at accounting for and narrowing the cybercriminal space of means, opportunities, and motives; the other aiming at augmenting early and pro…
Future of the media : sights from the inside
2012
Journalists as workers and makers of news are a very important stakeholder group for news media companies. It is vital for organizations to acknowledge the needs and expectations of their stakeholders, because fulfilled expectations lead to stakeholder favor and good organizational reputation. Unmet expectations lead to loss of stakeholder trust and bad organizational reputation. The purpose of this master’s thesis was to map the expectations and experiences of journalists and freelancer journalists working for major Finnish media companies. The aim was to find out how journalists see the future of media and their own future roles as journalists, how social media has affected journalists’ w…
Adaptive variable structure fuzzy neural identification and control for a class of MIMO nonlinear system
2013
This paper presents a novel adaptive variable structure (AVS) method to design a fuzzy neural network (FNN). This AVS-FNN is based on radial basis function (RBF) neurons, which have center and width vectors. The network performs sequential learning through sliding data window reflecting system dynamic changes, and dynamic growing-and-pruning structure of FNN. The salient characteristics of the AVS-FNN are as follows: (1) Structure-learning and parameters estimation are performed automatically and simultaneously without partitioning input space and selecting initial parameters a priori. The structure-learning approach relies on the contribution of the size of the output. (2) A set of fuzzy r…
MATHEMATICS IN THE CONTEXT OF FUZZY SETS: BASIC IDEAS, CONCEPTS, AND SOME REMARKS ON THE HISTORY AND RECENT TRENDS OF DEVELOPMENT
2011
The main aim of this paper is to discuss the basic ideas and concepts of the so called ‘Fuzzy Mathematics’ and to give a brief survey of the history and of some trends in recent development of mathematics and its applications in the context of fuzzy sets. As a potential reader we imagine a mathematician, who is not working in the field of ‘fuzzy mathematics’, but wishes to have some idea about this vast field in modern science.

Determinismo vs probabilidad en la enseñanza de la Física
1999
Incluye resumen en inglés. Este artículo pertenece al Monográfico: La Ciencia a las puertas del Tercer Milenio (II) Debido a la reducción del tiempo para enseñar Física en todos los niveles (secundaria y universidad), es muy importante seleccionar contenidos. Un buen criterio es que los contenidos sean importantes para la propia disciplina, pero otro es que esos contenidos puedan ser interesantes para los alumnos. Ideas tales como determinismo, reversibilidad y probabilidad, reunen ambas características. Pero si un concepto, ley, etc. merece ser seleccionado, merece ser bien enseñado y, por ello, es conveniente que se use más de una vez y, a ser posible, en diferentes contextos. Esto es lo …
The XMM Cluster Outskirts Project (X-COP): Thermodynamic properties of the Intracluster Medium out to $R_{200}$ in Abell 2319
2018
We present the joint analysis of the X-ray and SZ signals in A2319, the galaxy cluster with the highest signal-to-noise ratio in Planck maps and that has been surveyed within our XMM Cluster Outskirts Project (X-COP). We recover the thermodynamical profiles by the geometrical deprojection of the X-ray surface brightness, of the SZ comptonization parameter, and an accurate and robust spectroscopic measurements of the temperature. We resolve the clumpiness of the density to be below 20 per cent demonstrating that most of this clumpiness originates from the ongoing merger and can be associated to large-scale inhomogeneities. This analysis is done in azimuthally averaged radial bins and in eigh…
