Exploiting EDCA for Feedback Channels in Hybrid VLC/WiFi Architectures
2021
In this paper, we consider integrating VLC and WiFi technologies in a scenario in which Light-Emitting-Diodes (LEDs), acting as network access points (APs) for ultra-dense Internet of Things applications, are deployed into an indoor lighting infrastructure. In such a scenario, RF-links can be exploited for complementing VLC-links in dealing with mobility and bidirectional communications, which can be problematic due to the limited coverage areas and self-generated interference of VLC APs. In particular, we consider the possibility of supporting a technology-based duplexing scheme, in which downlink and uplink transmissions are performed by means, respectively, of VLC and WiFi interfaces int…
Managed Multiculturalism in Finnish Media Initiatives
2007
This paper focuses on Finnish mainstream journalism featuring multiculturalism. Three different initiatives are analysed with a qualitative text method founded on discourse and frame analysis. Finnish mainstream journalism took a multicultural turn in the mid-990s, two decades later than in neighbouring Sweden where similar initiatives were launched in the 1970s. The paper takes a critical look at the power relations these initiatives assert or transgress, how multicultural discourses position various actors in society, and how the mainstream media encounter cultural and ethnic differences in a changing demographic situation with a positive intention.
Balancing the Frame of Threat: Uninvited Migrants in the Finnish News
2010
This chapter analyzes Finnish news journalism concerning asylum seekers and undocumented migration. It focuses on 'the variety of others', the media not only construct a division between 'us' and 'them,' but also create varieties of 'others.' The solution to the problems related to otherness is not, however, to recognize that we are all different, as the currently popular discourse that celebrates 'cultural diversity' often claims. This chapter scrutinizes the frames of 'threat' and 'victim' which are typical of the media’s coverage of asylum seekers and undocumented migrants. To identify the narrative, I have analyzed what is defined as problems and what is offered as the causes of and sol…
Address Event Representation (AER) approach to resistive sensor arrays
2020
Address event representation (AER) has become an excellent strategy when approaching traditional frame based applications, mainly vision sensors. In this paper, and Within this scope, the potential of the AER paradigm is demonstrated when considering resistive (non-vision) sensor arrays. For showing quantitative evidences, MOS AMS 0.35 μm versions of some of the circuit cells typically used in AER systems, such as Winner-Take-All (WTA) circuits, have been implemented and analyzed. In these unit-cells, basic resistance-controlled sources are considered as per sensing devices. Preliminary simulation results demonstrate that this approach is valid for a wide range of resistive sensors.
Frame-based and frameless endoscopic procedures in the third ventricle.
1997
Stereotactic guidance is useful for planning an accurate trajectory to the third ventricle. A guiding block with a ball joint was developed for frame-based endoscopy and adaptors for arm-based and armless navigation systems. Between 1992 and 1996, 52 patients were operated on endoscopically in the third ventricle under stereotactic guidance. Thirty-eight ventriculostomies, 13 biopsies and 10 cystic lesions were performed. The coordinates of two points were calculated; one in the foramen of Monro and the second in the third ventricle. The ventriculostomy was performed under endoscopic control bluntly with a Fogarty catheter in front of the basilar artery. Twenty-seven (71%) of the patients h…
Análisis de contenido de la representación del cuerpo en un libro de texto de Educación Preescolar
2012
La construccion social y cultural del cuerpo influye en el conocimiento personal y de los otros. Los libros de texto transmiten el capital cultural de una sociedad a sus ciudadanos mas pequenos. El objetivo del estudio consiste en describir la forma en que se representa el cuerpo en las imagenes de un libro de texto de educacion preescolar. Se realizo un analisis de contenido de las imagenes a traves de un codigo elaborado en estudios previos. Las ninas y ninos son representados con gran diferencia respecto a otros sectores poblacionales y se observo igualdad de presencia de mujeres y hombres independientemente de su edad. Con gran diferencia se representa un cuerpo entero vestido con ropa …
A note on modified Gabor frames
2001
In this paper we generalize a procedure, originally proposed by Kaiser, which produces a family of (A, B)-frames in ℒ2(R), starting from a given Gabor (A, B)-frame. The procedure is applied to several examples. © Società Italiana di Fisica.

Ranking lists and European Framework Programmes: Does university status matter for performance in Framework Programmes?
2011
The operational context for higher education institutions has become increasingly competitive: universities have to compete on national and international markets for students, staff, funding and prestige. In this context, universities have increasingly become to think of themselves as actors who are in direct competition with others, and adapt their strategies to increase their status and survive in the new environment. The possibly best-known approach to measuring the status of universities is through the various ranking lists. Though focusing on different indicators like scientific performance or reputation, ranking lists can be considered as a mechanism for highlighting and even creating…
The Protection of the Right of Freedom on the European Union Level: The European Arrest Warrant and Non-custodial Pre Trial Measures. The Guideline o…
2012
“Protection of fundamental rights in particular must be central to the operation of the system:” this formula, found at the heart of the most recent official assessment of the EAW (2011), perfectly summarizes, in terms of political policy, the progressive shift of emphasis from efficiency and security towards the primacy of the protection of individual rights across the entire field of EU measures restricting individual liberty. The experience gained in terms of the principle of proportionality thus becomes a basic paradigm for the interpretation of the system in terms of applied law. The three levels through which the filter of proportionality has operated in the system of the EAW (multile…
