Mapping the dilemmatic space of early childhood education and care practitioners when challenged by children’s curiosity
2018
This article explores the notion of curiosity as a gateway to value dilemmas in early childhood education and care practices. The concept of dilemmatic space (Honig) is used to highlight the complexity of educational practices. Through an ethnographic approach based on video-observation and stimulated recall interviews, the reflections of the practitioners in three early childhood education and care institutions in Norway are analysed regarding situations in which curiosity was challenging and in which explorative behaviour was stopped, transferred or adjusted. The analyses allowed the construction of several axes of dilemmatic space, such as Equality versus Supporting the Individual, Socia…

A study of mobility and reachability in ad hoc networks using stochastic activity networks
2006
The integration of ad-hoc networks into real environments is now becoming more and more common and supervision and control systems are no exception. The efficiency of the communication in these networks as well as various other factors, are governed by the working area, the number of nodes, mobility, transmission power, etc. In this paper, the mobility and reachability of mobile nodes appearing spontaneously in a large installation such as can be found in a water purification system are studied. These nodes form an ad-hoc network and communicate between each other in order to finally reach a fixed node which can offer them information from the rest of the system in real time or act as a gat…
DEMO: Unconventional WiFi-ZigBee communications without gateways
2014
Nowadays, the overcrowding of ISM bands is becoming an evident limitation for the performance and widespread usage of 802.11 and 802.15.4 technologies. In this demo, we prove that it is possible to opportunistically exploit the inter-technology interference between 802.11 and 802.15.4 to build an unconventional low-rate communication channel and signalling protocol, devised to improve the performance of each contending technology. Differently from previous solutions, inter-technology communications do not require the deployment of a gateway with two network interfaces, but can be activated (when needed) directly between two heterogeneous nodes, e.g. a WiFi node and a ZigBee node. This capab…
Espressioni territoriali in evoluzione: cause, effetti, ipotesi di sviluppo
2013
I fenomeni della globalizzazione, dell’economia mondiale, dell’economia dell’informazione e della conoscenza stanno producendo trasformazioni nell’assetto spaziale dei sistemi urbani. Essendo i luoghi espressione delle dinamiche economiche e sociali, le città, tornate ad essere al centro dell’attenzione in quanto rappresentano gli spazi in cui le dinamiche globali si esprimono e si territorializzano, sono in costante riorganizzazione e necessitano di un’adeguata pianificazione del loro sviluppo al fine di creare nuove configurazioni spazio-funzionali, nuove espressioni territoriali strutturate per far convergere i flussi globali e generarne nuovi.
Real-Life Experiments based on IQRF IoT Testbed: From Sensors to Cloud
2018
Master's thesis Information- and communication technology IKT590 - University of Agder 2018 Internet of things (IoT) is the next generation internet technology which connects devices and objects intelligently to control data collected by diverse types of sensors, radio frequency identification and other physical objects. To address the challenges in IoT such as integrating artificial intelligent techniques with IoT concept, developing green IoT technologies and combining IoT and cloud computing, various platforms which support reliable and low power wireless connectivity are required. IQRF is a recently developed platform for wireless connectivity. It provides low power, low speed, reliable…
Multi-purpose embedded communication gateway : system design and testbed implementation
2014
Masteroppgave i Informasjons- og kommunikasjonsteknologi IKT590 Universitetet i Agder 2014 This dissertation revolves around developing a multi-purpose embedded communication gateway. The gateway is equipped with multiple communication interfaces including Ethernet, Bluetooth, WiFi, Zigbee, LTE, and it can be configured and utilized for many purposes, such as a failover of an Ethernet cable via 4G in order to maintain the network connectivity. Raspberry Pi circuit board and the operating system Raspbian are selected as the hardware and the software platforms respectively. Different communication interfaces are coordinated by the Raspberry Pi and are configured via Linux scripts according to…
The spreading of the invasive italian wall lizard on Vulcano, the last island inhabited by the critically endangered aeolian wall lizard
2018
[EN] The Aeolian Wall Lizard (Podarcis raffoneae) is an endemic species of the Aeolian Archipelago of Italy (Mediterranean Sea). Its distribution is limited to three islets and two relict populations on a relatively large island: Vulcano (a population on the summit of Gran Cratere volcano and another on Capo Grosso promontory). The critically endangered Aeolian Wall Lizard is threatened by the introduction of the Italian Wall Lizard (Podarcis siculus), which successfully competes and hybridizes with the endemic lizard. The invasive lizard is widespread on Vulcano, although the literature does not provide the exact distribution. Our first aim was updating the distribution of the Italian Wall…
Internet of Things : a gateway centric solution for providing IoT connectivity
2016
The Internet of Things (IoT) is revolutionising the traditional Internet by extending it with smart everyday objects. Wearables, smart grids and home automation systems are just a few examples of the IoT. A noteworthy point is that the amount of devices connected to the Internet will rapidly grow with the IoT. The IoT typically involves devices that are constrained in terms of energy, memory and processing resources. Therefore, they also limit applying the existing Internet protocols to the IoT. New protocols have been designed for the IoT, all the way from the physical layer, to the application layer. This thesis presents an implementation for an IoT gateway, which enables connectivity to …
