NICE-MRP: a Near-Optimal Radio-Interference Aware Multi-path Routing Protocol for MANETs
2013
International audience; Nowadays, with the miniaturization of communication devices, dense and highly mobile ad-hoc networks are very common. Besides, more and more devices have several radio interfaces. In such an environment, multi-path routing should be considered. Yet, only few multi-path ad-hoc routing protocols take into account the radio-interferences which might arise between two geographically close routes. Moreover, they generally only forbid the addition of interfering paths rather than looking for a different, more optimized, solution. This paper presents NICE-MRP, a novel multi-path routing protocol for mobile ad-hoc networks giving efficient solutions with respect to physical …

Abstract This article explores trolling as a form of literary activity. It presents a number of specific types of trolling on the Russian-language Internet in connection with digital literature and the literary practices of various groups of Internet users. Techniques for writing provocative “troll-texts” were created and developed within subcultural groups in the 1990s. Later, from being a subversive practice known only to a few insiders, it became a mass technique described in meta-texts that identified rules for trolling and shared facts about its culture with all interested users. In the 2010s, the now popularised techniques of trolling came to be seen as effective strategies to deploy …
Learning Platforms: How to Make the Right Choice
2018
Learning through online platform opportunities is one way of organizing a technology-enhanced learning process. This chapter provides an overview of the place and role of learning platforms in the pedagogical process, defines the differences between learning platforms and learning management systems and offers a toolkit for evaluating learning platforms. The toolkit includes 22 criteria divided into 43 sub-criteria, which can be evaluated at 3 levels. This tool can help teachers, school administrators and other stakeholders to make a pedagogically based choice when it comes to choosing which learning platform solutions to use to scaffold student learning in a transformed learning process th…
UAV Communication Strategies in the Next Generation of Mobile Networks
2020
| openaire: EC/H2020/857031/EU//5G!Drones The Next Generation of Mobile Networks (NGMN) alliance advocates the use of different means to support vehicular communications. This aims to cope with the massive data generated by these devices which could affect the Quality of Service (QoS) of the associated applications, but also the overall operation carried out by the vehicles. However, efficient communication strategies must be considered in order to select, for each vehicle, the communication mean ensuring the best QoS. In this paper, we tackle this issue and we propose efficient communication strategies for Unmanned Aerial Vehicles (UAVs). In addition to direct UAV-to-Infrastructure communi…
Electronic surveillance in the couple: The role of self-efficacy and commitment
2021
Abstract Researchers have shown a significant effect of using social networking sites (SNSs) on romantic relationships. Surveillance is one of the motives for social network use. Social networking surveillance is related to controlling a romantic partner's online behaviours. The purpose of the study was to search for antecedents of electronic surveillance (Study 1) and to examine their role in behaviours related to electronic surveillance among romantic couples (Study 2). Following the uses and gratification theory and technology acceptance model of using SNSs, antecedents of electronic surveillance in adult Facebook users were examined. In Study 1, the relationship between electronic surve…
Work-Family Border Styles and Mobile Technology
2018
Technological innovations and particularly mobile technology have many, complex implications for social life. All in all, mobile technology creates a paradox for employed parents: mobile phones enable better coordination and lower parents’ anxiety over family routines, yet the use of mobile technology increases the need for multitasking and increases the emotional burden of managing multiple roles. It is important to identify differences between workers as not everyone is able to use the possibilities of constant connectivity. This chapter addresses two interlinked topics: first, the possibility for employed parents to occupy different social domains concurrently with mobile technology and …
Automatic Detection of Hemangioma through a Cascade of Self-organizing Map Clustering and Morphological Operators
2016
Abstract In this paper we propose a method for the automatic detection of hemangioma regions, consisting of a cascade of algorithms: a Self Organizing Map (SOM) for clustering the image pixels in 25 classes (using a 5x5 output layer) followed by a morphological method of reducing the number of classes (MMRNC) to only two classes: hemangioma and non-hemangioma. We named this method SOM-MMRNC. To evaluate the performance of the proposed method we have used Fuzzy C-means (FCM) for comparison. The algorithms were tested on 33 images; for most images, the proposed method and FCM obtain similar overall scores, within one percent of each other. However, in about 18% of the cases, there is a signif…
MAC design on real 802.11 devices: From exponential to Moderated Backoff
2016
In this paper we describe how a novel backoff mechanism called Moderated Backoff (MB), recently proposed as a standard extension for 802.11 networks, has been prototyped and experimentally validated on a commercial 802.11 card before being ratified. Indeed, for performance reasons, the time critical operations of MAC protocols, such as the backoff mechanism, are implemented into the card hardware/firmware and cannot be arbitrarily changed by third parties or by manufacturers only for experimental reasons. Our validation has been possible thanks to the availability of the so called Wireless MAC Processor (WMP), a prototype of a novel wireless card architecture in which MAC protocols can be p…
Foreign literature as poison: (self-)censorship in the translation of German popular fiction in Italy during the 1930s
2018
Between the 1920s and 1930s, the translation of foreign contemporary novels into Italian was encouraged by publishers, meeting the needs of a new readership, which was larger and more heterogeneous than before the war. However, the sharp rise in the number of imported novels provoked strong disapproval. In a context of heightened nationalism and cultural autocracy, translation was considered a polluting, anti-patriotic and servile practice. The censorship that took place, however, was mostly implemented via a tacit compromise between the publishers and the regime, rather than by repressive institutional actions. In order to protect themselves from sanctions and requisitions, publishers and …
The Dimensions of Facebook Addiction as Measured by Facebook Addiction Italian Questionnaire and Their Relationships with Individual Differences
2017
Abstract The studies reported analyze the factorial structure of Facebook Addiction Italian Questionnaire (FAIQ), a variant of 20-item Young's Internet Addiction Test (IAT). In Study 1, we tested FAIQ psychometric properties using exploratory factor analysis (EFA). In Study 2, we performed a confirmatory factor analysis (CFA) to verify the FAIQ factorial structure identified through EFA. Results from CFA confirm the presence of a four-factor model accounting for 58 percent of total variance, plus a general higher order factor that best fits the data. Further relationships between FAIQ factor scores, personality, and Facebook usage have been explored.
