Out-of-plane strengthening of masonry infills using textile reinforced mortar (...
Akhoundi, Farhad; Silva, Luis M.; Vasconcelos, Graça; Lourenço, Paulo B.The out-of-plane collapse of masonry infills during seismic actions resulted in human life losses and huge repair or reconstruction costs. These problems will result in disturbance of the operational functions of the buildings. The main scope of this research is to analyze the efficiency of different strengthening techniques based on textile reinforced mortar (TRM) technique and using steel connectors in the ou...
Portuguese Football Federation consensus statement 2020
Abreu, Rodrigo; Figueiredo, Pedro; Beckert, Paulo; Marques, José P.; Amorim, Samuel; Caetano, Carlos; Carvalho, Pedro; Sá, Carla; Cotovio, RicardoNutrition is an undeniable part of promoting health and performance among football (soccer) players. Nevertheless, nutritional strategies adopted in elite football can vary significantly depending on culture, habit and practical constraints and might not always be supported by scientific evidence. Therefore, a group of 28 Portuguese experts on sports nutrition, sports science and sports medicine sought to discu...
Development of a compact and low-cost weather station for renewable energy appl...
Salgado, Jose A.; Feio, Miguel C.; Silva, Luis M.; Monteiro, Vítor Duarte Fernandes; Afonso, João L.; Afonso, José A.This paper describes the development of a weather station integrating several sensors which allows the measurement and data storage of the following environmental parameters: solar irradiance, temperature, humidity, wind speed, and wind direction. The collected data is later transferred to a mobile device, where it is stored in a database and processed in order to be visualized and analyzed by the user. For suc...
Seismic performance of Portuguese masonry infill walls: From traditional system...
Silva, Luis M.; Vasconcelos, Graça; Lourenço, Paulo B.; Akhoundi sheik hahmad loo, FarhadThe use of masonry infill walls in reinforced concrete structures are a common solution in Portugal and other European countries for more than 50 years. These walls are used as exterior enclosures to build the envelope of the buildings, or as interior partitions to divide the different spaces of the houses. In the building construction practice these walls are built only after the hardening of the reinforced co...
In-plane behavior of cavity masonry infills and strengthening with textile rein...
Akhoundi, Farhad; Vasconcelos, Graça; Lourenço, Paulo B.; Silva, Luis M.; Cunha, Fernando; Fangueiro, RaúlThe seismic vulnerability of masonry infilled reinforced concrete (rc) frames observed during past earthquakes in some south European countries resulted in losses of human lives and huge repair or reconstruction costs, justifies the need of deeper study of the seismic behavior of masonry infills enclosed in rc frames. Therefore, the main goals of this study are related to: (1) better understanding of the cyclic...
SHStream: Self-Healing Framework for HTTP Video-Streaming
Cunha, Carlos Augusto da Silva; Silva, Luis M.HTTP video-streaming is leading delivery of video content over the Internet. This phenomenon is explained by the ubiquity of web browsers, the permeability of HTTP traffic and the recent video technologies around HTML5. However, the inclusion of multimedia requests imposes new requirements on web servers due to responses with lifespans that can reach dozens of minutes and timing requirements for data fragments ...
