- CH-Resilience Project (Cultural Heritage: Resilience of Built Heritage and Built Environment): Internationalization and Research Network within the “Universitas Montium” (UNITA) AlliancePublication . Martins, Ana M. T.; Nepomuceno, Miguel C. S.; Simão, Inês Cunha; Juan García, Natalia; Campelo-Gaínza, Carlos; Pedro Lorente, Jesús; Salvado, João Pedro Ferreira; Rodrigues, Tiago; Cabeleira, João; Amoreira, SofiaThis paper presents the research work within the international Consortium Alliance "Universitas Montium" (UNITA) according one of many UNITA’s Research Projects: the Portuguese Project CH-RESILIENCE “Cultural Heritage: Resilience of Built Heritage and Built Environment” at the University of Beira Interior (UBI) within Universitas Montium Aliance which is included in UNITA's Research & lnnovation Cartography WP4, concerning Cultural Heritage. and soon to be included in the consortium RE-UNITA (UNITA 2.0). Within this research line two international PhD cotutelle were achieved, but also two other PhD thesis are being prepared within CH-RESILIENCE. The Department of Civil Engineering and Architecture (DECA), of the University of Beira Interior (UBI), has developed, a concern regarding Built Heritage, ln fact, over the last two decades there has been a cross-interdisciplinary interest, which has allowed a transdisciplinary research, based on the Architectural Heritage, Built Heritage, thus Cultural Heritage. Dissertation themes have focused on traditional aspects of Portuguese Architecture and Traditional Building Technologies, but also doctoral Thesis and Research Projects with competitively-based contests with funding (as The ORFEUS project which was one of the highlights of this line of research). In fact, Building Culture encompasses existing buildings, monuments, and other elements of Cultural Heritage, as well as the design and construction of contemporary buildings, infrastructures, public spaces, and landscapes. The actual technical requirements are not always compatible with older buildings. Regular maintenance of these buildings may include preservation, rehabilitation, restoration, reconstruction, refurbishment, adaptation, and interpretation of existing buildings and their environment. ln fact, this research lays on the Resilience of Built and Cultural Heritage. UNITA’s Research and innovation is centred in the needs of rural and mountain territories regarding, not only Cultural Heritage, but also Renewable Energy and Circular Economy. This paper presents four case study of international research based on the UNITA’s Alliance and interconnected with CH Resilience Project: “The Art of Place”, Cotutelle (UBI -Portugal / UNIZAR-SPAIN); “The involvement of local museums with their territorial and historical environment”, Cotutelle (UNIZAR-SPAIN / UBI -Portugal); Corbelled Dome Constructions: architectural elements of a vernacular Identity in Beira Baixa (Portugal); Resilience and Sustainability: Monastic Spaces of Cistercian origins in contemporary times. Besides these four cases it is highlighted, a fifth which is the first project, within the CH Resilience research group, in collaboration with other institutions with affinity to the theme and in the borderline of UNITA Alliance. This is the ongoing PhD thesis “Theory, Design and Construction of the Bulwark Defensive System in the Minho River Valley. From the Reign of King Philip III to the End of the Seven Years' War, 1621-1763”. Consequently, this paper will bring to discussion these specific case studies and its relationship with UNITA's Alliance. This is, through Cultural heritage it will be brought to debate methods, objectives, experiences, outputs, and discussions which allow the formation of wider networks for research and resources exchange.
- Design of Communication and Control for Swarms of Aquatic Surface DronesPublication . Christensen, Anders Lyhne; Oliveira, Sancho; Postolache, Octavian; Oliveira, Maria João de; Sargento, Susana; Santana, Pedro; Nunes, Luis; Velez, Fernando J.; Sebastião, Pedro; Costa, Vasco; Duarte, Miguel; Gomes, Jorge; Rodrigues, Tiago; Silva, FernandoThe availability of relatively capable and inexpensive hardware components has made it feasible to consider large-scale systems of autonomous aquatic drones for maritime tasks. In this paper, we present the CORATAM and HANCAD projects, which focus on the fundamental challenges related to communication and control in swarms of aquatic drones. We argue for: (i) the adoption of a heterogeneous approach to communication in which a small subset of the drones have long-range communication capabilities while the majority carry only short-range communication hardware, and (ii) the use of decentralized control to facilitate inherent robustness and scalability. A heterogeneous communication system and decentralized control allow for the average drone to be kept relatively simple and therefore inexpensive. To assess the proposed methodology, we are currently building 25 prototype drones from off-the-shelf components. We present the current hardware designs and discuss the results of simulation-based experiments involving swarms of up to 1,000 aquatic drones that successfully patrolled a 20 km-long strip for 24 hours.
- Experimental Characterization of WSNs Applied to Swarms of Aquatic Surface DronesPublication . Velez, Fernando J.; Nadziejko, Aleksandra K. N.; Christensen, Andersen; Oliveira, Sancho; Rodrigues, Tiago; Costa, Vasco; Duarte, Miguel; Silva, Fernando; Gomes, JorgeANCAD project aims at developing technologies and communication protocols for swarms of aquatic inexpensive surface drones. The goal is to perform maritime tasks such as sea border patrolling or environmental monitoring, keeping the cost of the drones low. The exchange of information within the swarm is essential for the success of the mission. The most recent solution for control and communications within the current prototypes are supported by Raspberry Pi 2 and XBee-PRO S1 allowing for low power consumption while expanding the range of transmission. Field trial results enabled to verify the potential of the proposed solution, in terms of coverage range and multi-hop capabilities, in actual maritime scenarios.
- Wireless Sensor and Networking Technologies for Swarms of Aquatic Surface DronesPublication . Velez, Fernando J.; Nadziejko, Aleksandra; Christensen, Anders Lyhne; Oliveira, Sancho; Rodrigues, Tiago; Costa, Vasco; Duarte, Miguel; Silva, Fernando; Gomes, JorgeIn this paper, we discuss wireless sensor and networking technologies for swarms of inexpensive aquatic surface drones in the context of the HANCAD project. The goal is to enable the swarm to perform maritime tasks such as sea-border patrolling and environmental monitoring, while keeping the cost of each drone low. Communication between drones is essential for the success of the project. Preliminary experiments show that XBee modules are promising for energy efficient multi-hop drone-to-drone communication.
