Abstract. The project Viable Alternative Mine Operating System (iVAMOS!) develops a novel underwater mining technique for extracting inland mineral deposits in flooded open-cut mines. From a floating launch and recovery vessel a remotely-operated underwater mining vehicle with a roadheader cutting machine is deployed. The cut material is transported to the surface via a flexible riser hose. Since there is no direct intervisibility between the operator and the mining machine, the data of the sens...

O topico da maldicao de Ham foi um instrumento central na construcao do pensamento europeu sobre a alteridade do africano e, em particular, como estrategia justificativa para a escravidao e o trafico atlântico. A regiao centro-ocidental do continente africano foi, ao mesmo tempo, a regiao mais intensamente envolvida no trafico de escravos e aquela onde a relacao cultural com a Europa se revelou mais duradoura. No estudo presente analisa-se o uso do topos da maldicao de Ham na literatura missiona...

This paper presents the positioning, navigation and awareness (PNA) system developed for the Underwater Robotic Mining System of the !VAMOS! project [1]. It describes the main components of the !VAMOS! system, the PNA sensors in each of those components, the global architecture of the PNA system, and its main subsystems: Position and Navigation, Realtime Mine Modeling, 3D Virtual reality HMI and Real-time grade system. General results and lessons learn during the first mining field trial in Lee ...

This paper describes the UX-l underwater mine exploration robotic system under development in the context of the UNEXMIN project. UNEXMIN is an international innovation action funded under the EU H2020 program, aiming to develop new technologies and services allowing the exploration of flooded underaround mines. The system is comprised by the UX-l robot prototype, launch and recovery system, command and control subsystem and a data management and post-processing computational infrastructure. The...

This paper presents EVA, a new concept for an hybrid ROV/AUV designed to support the underwater operation of an underwater mining machine, developed in the context of the European H2020 R&D iVAMOS! Project. This project is briefly presented, introducing the main components and concepts, providing the reader with clear picture of the operational scenario and allowing to understand better the functionality requirements of the support robotic vehicle developed. The design of EVA is detailed present...

AbstractThe purpose of this study was twofold: (1) to analyse the influence of the level of competition (First and Second Divisions) on the magnitude of home advantage (HA) in Portuguese futsal; (2) to examine whether the HA has changed over the recent years in Portugal. Data from 6.558 matches contested in First (n = 2.002) and Second (n = 4.556) Divisions of Portuguese futsal over the last 11 seasons (from 2006–07 to 2016–17) were collected and analysed. The mean values of HA were significantl...

O cristianismo constitui uma das principais marcas da presenca europeia no espaco cultural da Africa Central. Desde o batismo do soberano de Mbanza Kongo, ocorrido em 1491, simbolos, rituais, praticas cerimoniais foram incorporadas em algumas sociedades, ao ponto de alguns autores falarem de um “cristianismo africano”. O presente texto debruca-se sobre tres guias para a acao missionaria elaborados por religiosos capuchinhos que passaram pela regiao entre o ultimo quartel do seculo XVII e meados ...

This paper aims at presenting the STRONGMAR Summer School 2016 that took place at the Base Naval de Lisboa, of the Portuguese Navy. The STRONGMAR project ideal motivates the development of maritime and marine science research and technology through the knowledge transfer between INESC TEC and promising, and prestigious, leading research European institutions. This process takes place through theoretical lectures and training, and via experimental application of the concepts discussed in order to...

This study aimed to examine the influence of level of competition (amateur, semi-professional and professional) on the magnitude of home advantage (HA) in Portuguese football, and to verify whether the HA has changed over time. Archival data from 32,400 matches contested in the three levels of competition over 11 seasons (from 2005/2006 to 2015/2016) were analysed. HA was quantified each season for each league as the number of points won at home expressed as a percentage of all points won at hom...
