The advent of online social networks (OSNs) paired with the ubiquitous proliferation of smartphones have enabled social sensing systems. In the last few years, the aptitude of humans to spontaneously collect and timely share context information has been...
A novel approach to modeling online user behavior extracts and analyzes digital DNA-inspired sequences from users’ online actions. Standard DNA analysis techniques can then discriminate between genuine and spambot accounts.
Inspired by biological DNA, we model the behaviour of online users as “Digital DNA” sequences, introducing a strikingly novel, simple, and effective approach to discriminate between genuine and spambot online accounts.
Fake followers are those Twitter accounts specifically created to inflate the number of followers of a target account. Fake followers are dangerous for the social platform and beyond, since they may alter concepts like popularity and influence in the...
The descriptor function framework is used as tool for the control management of a swarm of dynamic agents. In this framework, a provision is made for obstacle and collision avoidance, thus improving the potential of the methodology from previous...
Car pooling is expected to significantly help in reducing traffic congestion and pollution in cities by enabling drivers to share their cars with travellers with similar itineraries and time schedules. A number of car pooling matching services have been...
Human-machine interfaces for command and control of teams of autonomous agents is an enabling technology for the development of reliable multi-agent systems. Tools for proper modelling of these systems are sought in order to ease the creation of...
A Serious Game (SG) system for the assessment of the potential of the multi-vehicle surveillance is presented. The SG system is applied to the problem of protection of strategic assets from underwater asymmetric threats. The SG platform integrates the...
This work proposes a game theoretic approach to tackle the problem of multi-robot coordination in critical scenarios where communication is limited and the robots must accomplish different tasks simultaneously. An important application falls in...
This paper presents a cooperative, distance-based, distributed control law for multiple Autonomous Underwater Vehicles (AUVs) executing a mission while meeting mutual communications constraints. The classic graph theory provides the essential tools to...
Published in: Acoustics, Speech and Signal Processing (ICASSP), 2016 IEEE International Conference on In this paper we focus on the relative position and orientation estimation between rigid bodies in an anchorless scenario. Several sensor units are...
This paper presents a cooperative and distributed control law for multiple Autonomous Underwater Vehicles (AUVs) executing a mission while meeting mutual communication constraints. Virtual couplings define interaction control forces between neighbouring...
Both TASTE and Overture have successfully demonstrated that method integration is a very promising strategy to create robust and effective tool suites. We show how the automated generation of bidirectional translation functions between VDM and ASN.1...
This paper shows a technique for the fabrication of an electrical (and thermal) contact on the top ends of a large number of vertical silicon nanowires, which are fabricated perpendicularly to a silicon wafer ( silicon nanowire forest). The technique is...
A complete embedded system implementing a SpaceFibre Link Analyser has been presented. SpaceFibre is the forthcoming standard for on-board satellite communications and there is a strong necessity for a test equipment able to validate the devices that...
IEEE 802.15.4e Time Slotted Channel Hopping (TSCH) standard has gained a lot of attention within the Industrial Internet of Things research community due to its effectiveness in improving reliability and providing ultra-low power consumption for...

Sensing, computing and communication are the main features of a wireless sensor network (WSN) which serves a wide range of applications. Despite its versatility and simplicity, it brought up various challenges such as limited storage, power consumption...
Nowadays, Software-Defined Networking (SDN) is a powerful architectural model, decoupling control and forwarding planes through the abstraction of network elements and functionalities. As known, in SDN networks the controller is the key element since...
In this paper, we propose a Virtual Machine (VM) allocator for Cloud Computing Data Center (DC). We allocate a set of VMs on servers that are interconnected through a three-tier fat-tree network topology. VMs require four different resources: CPU,...
