Outdoor systems performance and upgrade
Lopes, L.; Andringa, S.; Assis, P.; Blanco, A.; Carolino, N.; Cerda, M.A.; Clemêncio, Filomena; Conceição, R.; Cunha, O.; Dobrigkeit, C.; Ferreira, M.Over the last two decades, the possibility of using RPCs in outdoors systems has increased considerably. Our group has participated in this effort by installing several systems and continues to work on their optimization, while simultaneously studying and developing new approaches that can use RPCs in outdoor applications. In particular, four detectors were deployed in the field at the Pierre Auger Observatory ...
Influence of 3D microstructure for improving the thermal performance of buildin...
Lopes, L.; Almeida, Manuela Guedes de; Reis, D.The thermal performance of a building is highly dependent on the heat transmission through the envelope. On the other hand, additive manufacturing has been increasingly used in several industrial applications due to its possibility to produce complex structures. However, most studies of the 3d printing process focused on mechanical performance. This study aims to evaluate how the internal 3D-printed microstruct...
Projeto LouMu - Muografia no Lousal
Teixeira, Pedro; Blanco, A.; Caldeira, Bento; Tomé, B.; Matos, J.; Borges, José Fernando; Cazón, L.; Lopes, L.; Afonso, L.; Pinto, M.; Pimenta, M.A viabilidade da muografia como técnica de sondagem tem sido demonstrada em diversos trabalhos ao redor do mundo, desde os seus primeiros passos. A muografia com muógrafos em ambiente subterrâneo tem um lado fácil devido à ausência da radiação de fundo, mas, por outro lado, o fluxo de muões é muito menor em comparação com o que é medido na superfície. É uma questão de condições geológicas e subterrâneas, deteto...
TRIDENT – Technology based impact assessment tool foR sustaInable, transparent ...
Silva, E.; Viegas, D.; Martins, A.; Almeida, J.; Almeida, C.; Neves, B.; Madureira, P.; Wheeler, A. J.; Salavasidis, G.; Phillips, A.; Schaap, A.By creating a dependable, transparent, and cost-effective system for forecasting and ongoing environmental impact monitoring of exploration and exploitation activities in the deep sea, TRIDENT seeks to contribute to the sustainable exploitation of seabed mineral resources. In order to operate autonomously in remote locations under harsh conditions and send real-time data to authorities in charge of granting lic...

Muography in the university and in the museum
Afonso, L.; Alexandre, I.; Andringa, S.; Assis, P.; Blanco, O.; Bezzeghoud, M.; Borges, J.; Caldeira, B.; Cazon, L.; Costa, J.; Dobrilla, P.; Duarte, M.The LouMu team joins together specialists in particle detectors and in cosmic ray analyses, geophysicists and science communicators to muograph an underground gallery of an old mine, now open to visitors of a science museum. The muon telescope is made of Resistive Plate Chambers (RPCs) developed to operate stably and with low consumption at remote locations, and it has been tested in the Coimbra University, bef...
Muography for Underground Geological Surveys: Ongoing Application at the Lousal...
Teixeira, P.; Afonso, L.; Andringa, S.; Assis, P.; Bezzeghoud, M.; Blanco, A.; Borges, J. F.; Caldeira, B.; Cazon, L.; Dobrilla, P.; Lopes, L.The use of muons for geophysical surveys has been proved successful in numerous projects around the planet. The use of muography in an underground environment has an easy side, when compared to the surface, due to the absence of the background radiation. On the other hand, the muon flux is much lower than what is measured on the surface. Geological and underground conditions should be considered when defining t...
Combined Measurement of the Higgs Boson Mass in pp Collisions at s =7 and 8 TeV...
Aad, G.; Abbott, B.; Abdallah, J.; Abdinov, O.; Aben, R.; Abolins, M.; Abouzeid, O. S.; Abramowicz, H.; Abreu, H.; Abreu, R.; Abulaiti, Y.Made available in DSpace on 2022-05-02T18:42:56Z (GMT). No. of bitstreams: 0 Previous issue date: 2015-05-14; A measurement of the Higgs boson mass is presented based on the combined data samples of the ATLAS and CMS experiments at the CERN LHC in the H→γγ and H→ZZ→4 decay channels. The results are obtained from a simultaneous fit to the reconstructed invariant mass peaks in the two channels and for the two exp...
