O papel das transcrições do reportório erudito no desenvolvimento do acordeão d...
Santos, Pedro MiguelO presente Relatório Final da Prática de Ensino Supervisionada, que se insere no âmbito do Mestrado em Ensino de Música da Universidade de Aveiro, encontra-se dividido em duas partes. A primeira parte consiste num Projeto de Investigação que visa à verificação da função das transcrições do reportório erudito no desenvolvimento do acordeão desde o século XX. Foram empregues, igualmente, metodologias de pesquisa,...
Assessing short-range Shore-to-Shore (S2S) and Shore-to-Vessel (S2V) wifi commu...
D'Orey, Pedro; Gutiérrez Gaitán, Miguel; Santos, Pedro Miguel; Ribeiro, Manuel; Sousa, J. Borges de; Almeida, LuísWireless communications increasingly enable ubiquitous connectivity for a large number of nodes, applications and scenarios. One of the less explored scenarios are aquatic ecosystems, specially when enabled by near-shore and short-range communications. Overwater communications are impaired by a number of distinguishing dynamic factors, such as tides, waves or node mobility, that lead to a widely fluctuating and...
CoWiPS: Cooperative wireless positioning to identify position mis-reports in ve...
Lam, Luis; Santos, Pedro MiguelAutonomous driving (AD) is advancing rapidly, but enhancing situational awareness beyond the internal sensors (cameras, radar, and Lidar) requires cooperative perception services enabled by Vehicle-to-Everything (V2X) links. However, some vehicles can inject incorrect information, either intentionally or by hardware malfunction. Wireless positioning offers a set of physical-layer mechanisms, such as Angle-of-Ar...
Energy savings and emissions reduction of BEVs at an isolated complex intersection
Reddy, Radha; Almeida, Luis; Santos, Pedro Miguel; Kurunathan, Harrison; Tovar, EduardoImproving urban dwellers quality of life requires mitigating traffic congestion, minimizing waiting delays, and reducing fuel wastage and associated toxic air pollutants. Battery-electric vehicles (BEVs) are envisioned as the best option, thanks to zero exhaust emissions and regenerative braking. BEVs can be human-driven or autonomous and will co-exist with internal combustion engine vehicles (ICEVs) for years....
Cooperative Vehicular Platooning: A Multi- Dimensional Survey Towards Enhanced ...
Vasconcelos Filho, Ênio; Santos, Pedro Miguel; Koubaa, Anis; Tovar, Eduardo; Severino, RicardoCooperative Vehicular Platooning (Co-VP) is a paradigmatic example of a Cooperative Cyber-Physical System (Co-CPS), which holds the potential to vastly improve road safety by partially removing humans from the driving task. However, the challenges are substantial, as the domain involves several topics, such as control theory, communications, vehicle dynamics, security, and traffic engineering, that must be coup...
A WSSL Implementation for Critical Cyber-Physical Systems Applications
Rocha, Márcia; Vasconcelos Filho, Ênio; Alves, Fernando; Penna, Sergio; Santos, Pedro Miguel; Tovar, EduardoThe advancements in wireless communication technologies have enabled unprecedented pervasiveness and ubiquity of Cyber-Physical Systems (CPS). Such technologies can now empower true Systemsof-Systems, which cooperate to achieve more complex and efficient functionalities. However, for CPS applications to become a reality, safety and security must be guaranteed, particularly in critical systems, since they rely o...
Towards Safe Cooperative Autonomous Platoon systems using COTS Equipment
Kurunathan, John Harrison; Santos, José; Moreira, Duarte; Santos, Pedro MiguelThe domain of Intelligent Transportation Systems (ITS) is becoming a key candidate to enable safer and efficient mobility in IoT enabled smart cities. Several recent research in cooperative autonomous systems are conducted over simulation frameworks as real experiments are still too costly. In this paper, we present a platooning robotic test-bed platform with a 1/10 scale robotic vehicles that functions based o...
Joint Scheduling, Routing and Gateway Designation in Real-Time TSCH Networks
Gutiérrez Gaitán, Miguel; Almeida, Luis; Watteyne, Thomas; D'Orey, Pedro; Santos, Pedro Miguel; Dujovne, DiegoThis research proposes a co-design framework for scheduling, routing and gateway designation to improve the real-time performance of low-power wireless mesh networks. We target time-synchronized channel hopping (TSCH) networks with centralized network management and a single gateway. The end goal is to exploit existing trade-offs between the three dimensions to enhance traffic schedulability at systems' design ...
Improving the Performance of Cooperative Platooning with Restricted Message Tri...
Vasconcelos Filho, Ênio; Santos, Pedro Miguel; Severino, Ricardo; Koubaa, Anis; Tovar, EduardoCooperative Vehicular Platooning (Co-VP) is one of the most prominent and challenging applications of Intelligent Traffic Systems. To support such vehicular communications, the ETSI ITS G5 standard specifies event-based communication profiles, triggered by kinematic parameters such as speed. The standard defines a set of threshold values for such triggers but no careful assessment in realistic platooning scenar...
Work-in-Progress: Exploring the Composition of Synchronous Intelligent Intersec...
Reddy, Radha; Almeida, Luís; Santos, Pedro Miguel; Tovar, EduardoPrivate vehicles are expected to continue representing a large share of the urban traffic requiring intelligent management to provide safe and efficient urban mobility. In this context, it is imperative to mitigate traffic congestion and associated travel delays to improve the quality of life of urban dwellers. This paper explores the global performance of grid networks of independent intersections using differ...
