Joint Sub-Carrier and Power Allocation for Efficient Communication of Cellular UAVs
2020
| openaire: EC/H2020/857031/EU//5G!Drones Cellular networks are expected to be the main communication infrastructure to support the expanding applications of Unmanned Aerial Vehicles (UAVs). As these networks are deployed to serve ground User Equipment (UEs), several issues need to be addressed to enhance cellular UAVs’ services. In this paper, we propose a realistic communication model on the downlink, and we show that the Quality of Service (QoS) for the users is affected by the number of interfering BSs and the impact they cause. The joint problem of sub-carrier and power allocation is therefore addressed. Given its complexity, which is known to be NP-hard, we introduce a solution based …
Industrial Robot Collision Handling in Harsh Environments
2014
Doktorgradsavhandling i mekatronikk, Universitetet i Agder, 2014 The focus in this thesis is on robot collision handling systems, mainly collision detection and collision avoidance for industrial robots operating in harsh environments (e.g. potentially explosive atmospheres found in the oil and gas sector). Collision detection should prevent the robot from colliding and therefore avoid a potential accident. Collision avoidance builds on the concept of collision detection and aims at enabling the robot to find a collision free path circumventing the obstacle and leading to the goal position. The work has been done in collaboration with ABB Process Automation Division with focus on applicatio…
An exploratory study of gazing behavior during live performance
2009
It is known that the visual information given by performers during a performance works as a useful channel of communication to the audience. In my previous studies, many performers referred to the importance of gazing behavior or eye contact. The purpose of this research is to explore the role of gaze during live performance by measuring the timing and direction of gazing. The hypotheses are as follows: [1] Gazing behavior depends on the musical structure. [2] Gazing behavior is used for the communication between performers which is necessary during performance. [3] Performers set their gazing direction in order to contribute to the audience’s understanding of the music. This research was e…
Type of Delivery, Neuropsychological Development and Intelligence in Twin Births
2019
Based on a retrospective cohort design with six-year-old children born in twin births, the relationship between verbal, non-verbal, global neuropsychological development, general intelligence and type of delivery has been studied. To this end, the possible effect of third gestational, obstetric and neonatal variables, such as maternal age at delivery, fetal presentation, gestational age, newborn weight and Apgar at minute one, was controlled. The exposed cohort includes children born by cesarean section, and the unexposed cohort is composed of children born vaginally with or without induction. A total of 124 children were evaluated in their first year of primary school using the Child Neuro…
La costruzione simbolica del conflitto generazionale nei discorsi politici di Renzi e Grillo
2018
L’età dei parlamentari italiani e dei principali leader politici è stata al centro delle ultime campagne elettorali nazionali ed europee. In entrambi gli schieramenti, dalla “rottamazione” di Matteo Renzi agli “zombie in poltrona” di Beppe Grillo, gli slogan incitavano a uno svecchiamento della classe politica italiana. Ma chi è il giovane e chi l’anziano al quale si riferiscono i due leader? Quali sono i ruoli che essi prospettano per giovani e anziani? Quali sono le soglie costruite nei discorsi pubblici e nei post sui siti web ufficiali e sui profili nei social network dei due leader? Quale dialettica si è sviluppata? Quali analogie e differenze rispetto alle rappresentazioni proposte da…
Identity construction in a pwnage video on YouTube
2012
Internet on viimeisen vuosikymmenen aikana synnyttänyt lukemattomia uusia genrejä, joista huomattava osa pohjautuu vanhoihin, jo olemassaolleisiin genreihin. Toimintatavat, tarkoitukset ja saavutukset näissä genreissä ovat vielä melko tuntemattomia tutkimuskohteita kielitieteessä. Tässä tutkimuksessa toissijaisena tavoitteena oli selvittää uuden YouTube-genren, josta tässä käytän nimitystä argument pwnage, tyypillisiä piirteitä. Ensisijainen tavoite oli yhtä kyseiseen genreen kuuluvaa videota analysoiden tutkia, miten videon tekijän sosiaalinen identiteetti rakentuu pwnage-toiminnassa. Pwnage käsittää tässä yhteydessä vastustajan voittamista ideologisessa, yksipuolisessa väittelyssä, joka e…
A New Small Drifter for Shallow Water Basins: Application to the Study of Surface Currents in the Muggia Bay (Italy)
2016
A new small drifter prototype for measuring current immediately below the free surface in a water basin is proposed in this paper. The drifter dimensions make it useful for shallow water applications. The drifter transmits its GPS location via GSM phone network. The drifter was used to study the trajectory of the surface current in the Muggia bay, the latter containing the industrial harbor of the city of Trieste (Italy). The analysis has been carried out under a wide variety of wind conditions. As regards the behavior of the drifter, the analysis has shown that it is well suited to detect the water current since its motion is marginally affected by the wind. The study has allowed detecting…
Maldivian Tourist Resorts and their Environmental Impact
1993
In the past two decades, the Maldivians have built up a flourishing tourist industry. Tourist resorts have been established on hitherto uninhabited small islands and by 1990 the number of tourists has increased to nearly 200 000. The Maldivian tourist resorts represent a special type of tropical beach resorts catering only to the tourists’ needs for accommodation, board, leisure and recreation. They are distinctly separate from the islands inhabited by the Maldivians and intercultural communication does not take place. These resorts are in effect ‘tourist enclaves’. Holiday facilities in the resorts are clearly geared to the coastal environment - the beach, lagoon and reef. The impact of to…
Le forme della multimodalità. Segni, gesti e parole in classe.
2020
La comunicazione umana è un evento complesso e multimodale: nella interazione faccia a faccia, la maggior parte del significato viene veicolato attraverso il canale non verbale e l’analogico del linguaggio. L’attenzione a tale aspetto risulta cruciale nella relazione educativa tra insegnanti e alunni e nella didattica in classe . Il presente contributo intende quindi approfondire la nozione di multimodalità nelle diverse forme in cui si realizza esplorando cosa accade con le lingue vocali (in cui si utilizza il canale acustitco vocale) e con le lingue segniche (in cui si utilizza il canale visivo-gestuale). Viene definito, in primo luogo, il concetto di multimodalità nel linguaggio facendo …
Global connectedness in higher education : student voices on the value of cross-cultural learning dialogue
2015
The study explores how sense of global connectedness can be enhanced by creating opportunities for cross-cultural dialogue in higher education. Thematic analysis of randomly selected 15 learning journals, students’ reflections on their learning during an international seminar was used to identify students’ significant learning experiences. The results emphasise the added value of diversity (geographical, disciplinary, cultural and social) among students, faculty and invited presenters for creating meaningful learning. Furthermore, they suggest that designing an integrated approach of contents, contexts and activities for critical engagement in global dialogue and knowledge generation in hig…
